Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION During the second quarter, Kaman Corporation and subsidiaries (collectively "the Company") announced an agreement to sell Kaman Industrial Technologies Corporation and its subsidiaries (the "Distribution segment") to affiliates of Littlejohn & Co., LLC for $700.0 million in cash, subject to customary closing conditions and working capital adjustments. As a result of the agreement, the Distribution segment met "held for sale" criteria in the fiscal quarter ended June 28, 2019. The Distribution segment's results of operations and the related cash flows from this business have been reclassified to earnings from discontinued operations in the Condensed Consolidated Statement of Operations and cash flows from discontinued operations in the Condensed Consolidated Statement of Cash Flows, respectively, for all periods presented. The assets and liabilities of the Distribution segment have been reclassified to assets held for sale and liabilities held for sale, respectively, in the Condensed Consolidated Balance Sheets as of June 28, 2019 and December 31, 2018. The sale is expected to close during the third quarter of 2019, subject to customary closing conditions and the receipt of certain required consents and approvals. See Note 4, Discontinued Operations , to the Condensed Consolidated Financial Statements for further information. In the opinion of management, the condensed consolidated financial information reflects all adjustments necessary for a fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented, but do not include all disclosures required by accounting principles generally accepted in the United States of America ("US GAAP"). All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . The results of operations for the interim periods presented are not necessarily indicative of trends or of results to be expected for the entire year. The Company has a calendar year-end; however, its first three fiscal quarters follow a 13-week convention, with each quarter ending on a Friday. The second quarters for 2019 and 2018 ended on June 28, 2019 , and June 29, 2018 , respectively.

Recent Accounting Standards

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Standards	RECENT ACCOUNTING STANDARDS Recent Accounting Standards Adopted In February 2018, the FASB issued ASU 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income". The objective of this standard is to address the concern that tax effects of items within accumulated other comprehensive income do not appropriately reflect the tax rate because the Tax Cut and Jobs Act of 2017 ("Tax Reform") required the adjustment of deferred taxes be recorded to income. This ASU provides an entity the election to reclassify stranded tax effects resulting from Tax Reform to retained earnings from accumulated other comprehensive income. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The adoption of ASU 2018-02 resulted in an increase to retained earnings of $23.1 million , primarily related to the stranded tax effects resulting from Tax Reform for pension and other post-retirement benefits. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities". The objective of this standard update is to improve the financial reporting of hedging relationships to better reflect the economic results of an entity's risk management activities in its financial statements. This ASU expands hedge accounting for both nonfinancial and financial risk components and refines the measurement of hedge results to better reflect an entity's hedging strategies. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Adopted - continued In October 2018, the FASB issued ASU 2018-16, "Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes". The Federal Reserve Board and the Federal Reserve Bank of New York initiated an effort to introduce an alternative reference rate to LIBOR in the United States. This standard update permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption was permitted. The amendments in this ASU were required to be adopted concurrently with the amendments in ASU 2017-12. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Under this ASU as amended, lessees are required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged under this ASU as amended. This standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. On January 1, 2019, the Company adopted ASC 842 using the modified retrospective transition method allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result, the Company applied ASC 842 only to leases that existed as of January 1, 2019 and did not restate prior periods. The adoption of ASC 842 resulted in a net increase of approximately $90.0 million to its assets and liabilities as of January 1, 2019 due to the addition of right-of-use assets and lease liabilities for operating leases on the balance sheet; however, it did not have a material impact on the Company's cash flows, results of operations or debt covenant compliance. The majority of the right-of-use assets and lease liabilities recorded on January 1, 2019 for operating leases relate to the Distribution segment and were included in assets held for sale and liabilities held for sale, respectively, on the Company's Condensed Consolidated Balance Sheet as of June 28, 2019 . The Company has elected the following practical expedients (which must be elected as a package and applied consistently to all leases): an entity need not reassess whether any expired or existing contracts are or contain leases, an entity need not reassess the lease classification for any expired or existing leases and an entity need not reassess initial direct costs for any existing leases. Additionally, the Company has elected the practical expedient to not separate nonlease components from the associated lease component and account for those components as a single component for real estate leases. Nonlease components for the Company's vehicle and other equipment leases are not material. The Company has elected not to apply the recognition requirements to short-term leases, and will recognize the lease payments in profit or loss on a straight-line basis over the lease term and variable payments in the period in which the obligation for those payments is incurred. Subsequent to the issuance of ASU 2016-02, the FASB has issued the following updates: ASU 2018-10, "Codification Improvements to Topic 842, Leases", ASU 2018-11, "Leases (Topic 842): Targeted Improvements - Transition - Comparative Reporting at Adoption" and ASU 2019-01, "Leases (Topic 842): Codification Improvements". The amendments in these updates affect the guidance contained within ASU 2016-02 and were similarly adopted on January 1, 2019. See Note 3, Significant Accounting Policies Update , for further information on the impact of these standard updates. Recent Accounting Standards Yet to be Adopted In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses". The amendment clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 and impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Yet to be Adopted - continued In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". The objective of the standard update is to provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract to address the diversity in practice. The ASU requires an entity in a hosting arrangement that is a service arrangement to determine which costs to capitalize as an asset related to a service contract and which costs to expense, and to determine which project stage implementation activities relate to. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and postimplementation stages are expensed as the activities are performed. Capitalized implementation costs of a hosting arrangement are expensed over the term of the hosting arrangement in the same line item in the statement of operations as the fees associated with the hosting element of the arrangement. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. The amendments in this standard update should be applied either retrospectively or prospectively to all implementation costs incurred after the inception date. The Company has elected to adopt the standard update prospectively. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Disclosure Framework - Changes to Disclosure Requirements for Defined Benefit Plans". The objective of the standard update is to improve the effectiveness of disclosure requirements for defined benefit pension and other postretirement plans. This standard update removes disclosures that are no longer considered cost beneficial, clarifies specific requirements of disclosures and adds new disclosure requirements identified as relevant. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020. Early adoption is permitted. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurement". The objective of this standard update is to improve the effectiveness of disclosures for recurring and nonrecurring fair value measurements. This standard update removes certain disclosure requirements that are no longer considered cost beneficial, modifies existing disclosure requirements and adds new disclosure requirements identified as relevant. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of the ASU and delay adoption of the additional disclosures until the effective date. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The objective of this standard update is to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Under this ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. The standard update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The impact of the adoption of this standard update is dependent on the Company's goodwill impairment assessment. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". The objective of this standard update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. An entity will apply the amendments in this ASU through a cumulative-effect adjustment to retained earnings as of the first reporting period in which the guidance is effective. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Yet to be Adopted - continued Subsequent to the issuance of ASU 2016-13, the FASB has issued the following updates: ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments- Credit Losses", ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments" and ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326) - Targeted Transition Relief". The amendments in these updates affect the guidance within ASU 2016-13 and have been assessed with ASU 2016-13.

Accounting Policies [Abstract]
Significant Accounting Policies Update	SIGNIFICANT ACCOUNTING POLICIES UPDATE The Company's significant accounting policies are detailed in Note 1, Summary of Significant Accounting Policies of its Annual Report on Form 10-K for the year-ended December 31, 2018. Significant changes to our accounting policies as a result of adopting new accounting standards are discussed below: Leasing Under Accounting Standards Codification ("ASC") 842, the Company determines if a contract contains a lease at the inception date of the contract. To determine if the contract contains a lease, the Company evaluates if there is an identified asset in the contract and if the Company has control over the use of the identified asset. There is an identified asset in the contract if the asset is explicitly or implicitly specified in the contract, the asset is physically distinct or the Company has the right to receive substantially all of the asset's capacity, and if the supplier does not have substantive substitution rights. The Company has control over the use of the identified asset if the Company obtains substantially all economic benefits from the use of the asset and can direct the use of the asset. The Company applied the practical expedient for any contracts that existed prior to January 1, 2019; therefore, the contracts were not reassessed to determine if they contain leases. The Company must classify each lease as a finance lease or operating lease. A lease is classified as a finance lease if the Company will own the asset by the end of the lease term, the Company is reasonably certain to exercise the purchase option, the lease term covers a major part of the asset's economic life, the sum of the present value of the lease payments and the present value of the residual value guarantee not included in the lease payments equal or exceed substantially all of the fair value of the underlying asset at lease commencement or if the lessor has no alternative use for the asset. If any of these criteria are not met, the lease is classified as an operating lease. The Company applied the practical expedient for any leases that existed prior to January 1, 2019; therefore, the lease classifications of existing leases were not reassessed (all existing leases classified as operating leases under ASC 840 were classified as operating leases under ASC 842 on January 1, 2019 and all existing leases classified as capital leases under ASC 840 were classified as finance leases under ASC 842 on January 1, 2019). The Company's operating leases consist of rent commitments under various leases for office space, warehouses, land and buildings at varying dates from January 2019 to December 2024. The terms of most of these leases are in the range of 3 to 7 years, with certain leases renewable for varying periods and certain leases including options to terminate the leases. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so. It is expected that in the normal course of business leases that expire will be renewed or replaced by leases on other similar property. Some of the Company's leases have fixed amount rent escalations or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. The terms for most machinery and equipment leases range from 3 to 5 years. The majority of the Company's finance leases consist of assets purchased under the Company's master leasing agreement with PNC Equipment Finance ("PNC"), and are included in machinery, office furniture and equipment and construction in process. At June 28, 2019 , the Company's master leasing agreement with PNC had a maximum capacity of $20.0 million . The terms of these leases are 5 years. Amortization of these assets is included in depreciation and amortization expense. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued At the commencement date, the right-of-use asset and lease liability are recorded to the Company's Condensed Consolidated Balance Sheets when the Company obtains control of the use of the asset. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments upon entering into a lease agreement. The initial measurement of the lease liability is equal to the present value of the unpaid lease payments. Subsequent to the initial measurement, the lease liability continues to be measured at the present value of unpaid lease payments throughout the lease term. The lease liability is remeasured if the lease is modified and the modification is not accounted for as a separate contract, there is a change in the assessment of the lease term, the assessment of a purchase option exercise or the amount probable of being owed under a residual value guarantee, or a contingency is resolved resulting in some or all of the variable lease payments becoming fixed payments. The initial measurement of the right-of-use asset is equal to the total of the initial measurement of the lease liability, incremental costs to obtain the lease and prepaid lease payments, less any lease incentives received. Subsequent to the initial measurement, the right-of-use asset for a finance lease is equivalent to the initial measurement less accumulated amortization and any accumulated impairment losses. Generally, amortization of finance leases is recorded to cost of sales on a straight-line basis over the lease term. Subsequent to initial measurement, the right-of-use asset for an operating lease is equivalent to initial measurement less accumulated amortization (the difference between the straight-line lease cost for the period and the accretion of the lease liability using the effective interest method). The Company has elected not to apply the recognition requirements of ASC 842 to short-term leases (leases that, at the commencement date, have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise) as permissible under the standard. For short-term leases, the Company recognizes lease payments on a straight-line basis and variable payments in the period in which the obligation for those payments is incurred. Leasing contracts can be separated into lease components, non-lease components and items that are not components of the contract (items that do not transfer a good or service to the Company). Two or more contracts may be combined if at least one of which is or contains a lease entered into or near the same time with the same counterparty and consider the contracts as a single transaction if the contracts are negotiated as a package with the same objective, the amount of consideration to be paid in one contract depends on the price of performance of the other contract or the rights to use the underlying assets conveyed in the contracts are a single lease component. Lease components are considered separate if the Company can benefit from the right to use either on its own or together with other resources readily available to the Company and the right to use is not highly dependent or highly interrelated with the other rights to use the underlying assets in the contract. Consideration in the contract is allocated only to lease and non-lease components of a contract. The Company has elected the practical expedient allowing the Company to combine lease and non-lease components by class as a single lease component for its real estate leases. Nonlease components for the Company's vehicles and other equipment leases are not material. The lease term is the noncancellable period for which a lessee has the right to use an underlying asset, including periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. For renewal options, the Company performs an assessment at commencement if it is reasonably likely to exercise the option. The assessment is based on the Company's intentions, past practices, estimates and factors that create an economic incentive for the Company. Generally, the Company is not reasonably certain to exercise the renewal option in a lease contract as it performs an assessment for most real estate leases within six months prior to termination comparing the renewal rents under the option with the fair market returns for equivalent property under similar terms and conditions. Although the Company does not historically change locations often, it is not reasonably certain the Company will exercise the renewal option; therefore, the periods covered by the renewal option are not typically included in the lease term at commencement. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so; therefore, the Company does not typically consider the termination option in its lease term at commencement. Consideration in the contract is the sum of lease payments relating to the use of the underlying asset, fixed payments and other in-substance fixed payments, less any incentives received. Remeasurement of variable lease payments based on an index is only required if remeasurement is required for another reason, such as a change in lease term or change in estimates of probable payments under residual value guarantees. If remeasured, the remeasurement date becomes the new date for updating the payments based on the index. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued The Company uses the discount rate implicit in a lease contract, if available. As most of the Company's leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. For any leases that existed prior to the adoption of the standard, the Company used the incremental borrowing rate as of January 1, 2019 based on the type of asset and term of the lease. The Company separated its real estate leases by classes of lease terms and used the incremental borrowing rate consistent with its lease term class to determine the present value of lease payments. As most of the Company's vehicles have a four-year lease term, the Company used the incremental borrowing rate consistent with a four-year lease term for all vehicles. For all other equipment leases, the Company used the incremental borrowing rate consistent with a five-year lease term as the majority of the Company's leases for other equipment have a five-year lease term.

Restructuring Costs [Abstract]
Restructuring Costs	RESTRUCTURING COSTS During the third quarter of 2017, the Company initiated restructuring activities at its Aerospace segment to support the ongoing effort of improving capacity utilization and operating efficiency to better position the Company for increased profitability and growth. Such actions include workforce reductions and the consolidation of operations, beginning in the third quarter of 2017 through the planned completion of restructuring activities in 2019. The Company currently expects these actions to result in approximately $9.5 million in pre-tax restructuring and transition charges and, beginning in 2019, will result in total cost savings of approximately $4.0 million annually. The following table summarizes the accrual balances by cost type for the restructuring actions: Severance Other (1) Total In thousands Restructuring accrual balance at December 31, 2018 $ 1,022 $ 558 $ 1,580 Provision (15 ) 196 181 Cash payments (777 ) (378 ) (1,155 ) Changes in foreign currency exchange rates (8 ) (15 ) (23 ) Restructuring accrual balance at June 28, 2019 $ 222 $ 361 $ 583 (1) Includes costs associated with consolidation of facilities. The above accrual balance was included in other current liabilities on the Company's Consolidated Balance Sheets. Since the announcement of these restructuring activities, restructuring expense as of June 28, 2019 was $9.1 million . For the three-month and six-month fiscal periods ended June 28, 2019 , the Aerospace segment incurred $0.2 million and $ 0.5 million in costs, respectively, associated with the restructuring activities described above. Included in the expense for the three-month and six-month fiscal periods ended June 28, 2019 was $0.2 million and $0.3 million , respectively, of cost that relates to the write-off of inventory for various small order programs that the Company will no longer continue to manufacture as a result of the consolidation of operations. For the three-month and six-month fiscal periods ended June 29, 2018 , the Aerospace segment incurred $1.5 million and $ 2.3 million in costs, respectively, associated with the restructuring activities described above. 5. RESTRUCTURING COSTS (CONTINUED) Other Matters In addition to the restructuring above, for the three-month and six-month fiscal periods ended June 29, 2018 , the Aerospace segment incurred $0.3 million and $1.2 million in costs, respectively, associated with the termination of certain distributor agreements and separation costs for certain employees not covered by the restructuring activities noted above. These amounts are not included in the table above. The Distribution segment incurred $0.1 million in separation costs for certain employees in the three-month fiscal period ended June 29, 2018

Revenue from Contract with Customer [Abstract]
Contract Assets, Contract Costs and Contract Liabilities	CONTRACT ASSETS, CONTRACT COSTS AND CONTRACT LIABILITIES Contract assets consist of unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract costs consist of costs to obtain and fulfill a contract. Costs to fulfill a contract primarily consist of nonrecurring engineering costs incurred at the start of a new program for which such costs are expected to be recovered under existing and future contracts. Such costs are amortized over the estimated revenue amount of the contract. Costs to obtain a contract consist of commissions and agent fees paid in connection with the award of a contract. Contract liabilities consist of advance payments and billings in excess of costs incurred and deferred revenue. 7. CONTRACT ASSETS, CONTRACT COSTS AND CONTRACT LIABILITIES (CONTINUED) Reconciliation of Contract Balances Activity related to contract assets, contract costs and contract liabilities is as follows: June 28, December 31, 2018 $ Change % Change In thousands Contract assets (1) $ 118,774 $ 99,261 $ 19,513 19.7 % Contract costs, current portion $ 5,114 $ 5,993 $ (879 ) (14.7 )% Contract costs, noncurrent portion $ 9,187 $ 10,666 $ (1,479 ) (13.9 )% Contract liabilities, current portion (1) $ 30,707 $ 28,865 $ 1,842 6.4 % Contract liabilities, noncurrent portion (1) $ 72,081 $ 78,562 $ (6,481 ) (8.2 )% (1) Contract assets and contract liabilities of the Distribution segment were included in assets held for sale and liabilities held for sale, respectively, on the Company's Condensed Consolidated Balance Sheets. See Note 4, Discontinued Operations , for further information on the Company's agreement to sell the Distribution segment. Contract Assets The increase in contract assets was primarily due to the recognition of revenue related to the satisfaction or partial satisfaction of performance obligations during the six-month fiscal period ended June 28, 2019 . This increase was primarily related to work performed and not yet billed on the JPF program with the USG, and certain metallic structures programs, partially offset by amounts billed on the SH-2G program with Peru. There were no significant impairment losses related to the Company's contract assets during the three-month and six-month fiscal periods ended June 28, 2019 and June 29, 2018 . Contract assets includes amounts for matters such as contract changes, negotiated settlements and claims for unanticipated contract costs. These amounts are as follows: June 28, December 31, In thousands Contract changes, negotiated settlements and claims for unanticipated contract costs $ 3,574 $ 2,909 Contract Costs At June 28, 2019 , costs to fulfill a contract and costs to obtain a contract were $6.3 million and $8.0 million , respectively. At December 31, 2018 , costs to fulfill a contract and costs to obtain a contract were $8.9 million and $7.8 million , respectively. These amounts are included in contract costs, current portion and contract costs, noncurrent portion on the Company's Condensed Consolidated Balance Sheets at June 28, 2019 and December 31, 2018 . The decrease in contract costs, current portion was primarily attributable to the amortization of contract costs, partially offset by the reclassification of a portion of costs to obtain a JPF DCS contract and costs to fulfill certain metallic structures programs from contract costs, noncurrent portion. For the three-month and six-month fiscal periods ended June 28, 2019 , amortization of contract costs was $2.0 million and $3.0 million , respectively. For the three-month and six-month fiscal periods ended June 29, 2018 , amortization of contract costs was $ 1.0 million and $ 1.7 million , respectively. The decrease in contract costs, noncurrent portion was due to the reclassification of a portion of costs to obtain a JPF DCS contract and costs to fulfill certain metallic structures programs to contract costs, current portion. 7. CONTRACT ASSETS, CONTRACT COSTS AND CONTRACT LIABILITIES (CONTINUED) Contract Liabilities The increase in contract liabilities, current portion was primarily due to the reclassification of a portion of the advance payments received for a JPF DCS contract from contract liabilities, noncurrent portion and an advance payment received on the K-MAX® program, partially offset by revenue recognized on the K-MAX® program and a JPF DCS contract. For the three-month and six-month fiscal periods ended June 28, 2019 , revenue recognized related to contract liabilities, current portion was $6.0 million and $14.0 million , respectively. For the three-month and six-month fiscal periods ended June 29, 2018 , revenue recognized related to contract liabilities, current portion was $1.4 million and $ 6.4 million , respectively. The decrease in contract liabilities, noncurrent portion was due to the reclassification of a portion of the advance payments received for a JPF DCS contract to contract liabilities, current portion. For the three-month and six-month fiscal periods ended June 28, 2019 and June 29, 2018 , the Company did not recognize revenue against contract liabilities, noncurrent portion.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The following table presents the carrying value and fair value of financial instruments that are not carried at fair value: June 28, 2019 December 31, 2018 Carrying Value Fair Value Carrying Value Fair Value In thousands Debt (1) $ 312,796 $ 361,886 $ 299,124 $ 325,251 (1) These amounts are classified within Level 2. The above fair values were computed based on quoted market prices and discounted future cash flows (observable inputs), as applicable. Differences from carrying values are attributable to interest rate changes subsequent to when the transactions occurred. The fair values of cash and cash equivalents, accounts receivable, net and accounts payable - trade approximate their carrying amounts due to the short-term maturities of these instruments. Recurring Fair Value Measurements The Company holds derivative instruments for foreign exchange contracts that are measured at fair value using observable market inputs such as forward rates and its counterparties’ credit risks. Based on these inputs, the derivative instruments are classified within Level 2 of the valuation hierarchy. At June 28, 2019 and December 31, 2018 , the derivative instruments were included in other current liabilities on the Consolidated Balance Sheets. Based on the Company's continued ability to trade and enter into forward contracts and interest rate swaps, the Company considers the markets for its fair value instruments to be active. 8. FAIR VALUE MEASUREMENTS (CONTINUED) Recurring Fair Value Measurements - continued The Company evaluated the credit risk associated with the counterparties to these derivative instruments and determined that as of June 28, 2019 , such credit risks have not had an adverse impact on the fair value of these instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risks relating to its ongoing business operations, including market risks relating to fluctuations in foreign currency exchange rates and interest rates. Derivative financial instruments are recognized on the Condensed Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in the fair values of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedged transaction. Gains and losses on derivative instruments reported in accumulated other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not use derivative instruments for speculative purposes. Forward Exchange Contracts The Company holds forward exchange contracts designed to hedge forecasted transactions denominated in foreign currencies and to minimize the impact of foreign currency fluctuations on the Company’s earnings and cash flows. Some of these contracts are designated as cash flow hedges. The Company will include in earnings amounts currently included in accumulated other comprehensive income upon recognition of cost of sales related to the underlying transaction. These contracts were not material to the Company's Condensed Consolidated Balance Sheets as of June 28, 2019 and December 31, 2018 . The activity related to these contracts was not material to the Company's Condensed Consolidated Financial Statements for the three-month and six-month fiscal periods ended June 28, 2019 and June 29, 2018 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Pension Freeze Effective December 31, 2015, the Company's qualified pension plan was frozen with respect to future benefit accruals. Under USG Cost Accounting Standard (“CAS”) 413 the Company must determine the USG’s share of any pension curtailment adjustment calculated in accordance with CAS. Such adjustments can result in an amount due to the USG for pension plans that are in a surplus position or an amount due to the contractor for plans that are in a deficit position. During the fourth quarter of 2016, the Company accrued a $0.3 million liability representing its estimate of the amount due to the USG based on the Company's pension curtailment adjustment calculation, which was submitted to the USG for review in December 2016. The Company has maintained its accrual at $0.3 million as of June 28, 2019 . There can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on the Company's results of operations, financial position and cash flows. New Hartford Property In connection with the sale of the Company’s Music segment in 2007, the Company assumed responsibility for meeting certain requirements of the Connecticut Transfer Act (the “Transfer Act”) that applied to the transfer of the New Hartford, Connecticut, facility leased by that segment for guitar manufacturing purposes (“Ovation”). Under the Transfer Act, those responsibilities essentially consist of assessing the site's environmental conditions and remediating environmental impairments, if any, caused by Ovation's operations prior to the sale. The site is a multi-tenant industrial park, in which Ovation and other unrelated entities lease space. The environmental assessment process, which began in 2008, has been completed and site remediation is in process. The Company's estimate of its portion of the cost to assess the environmental conditions and remediate this site is $2.3 million , all of which has been accrued. The remediation has been substantially completed and the Company continues to monitor the results of the remediation. The total amount paid to date in connection with these environmental remediation activities is $1.6 million . At June 28, 2019 , the Company had $0.7 million accrued for these environmental remediation activities. A portion ( $0.1 million ) of the accrual related to this property is included in other current liabilities and the balance is included in other long-term liabilities. The remaining balance of the accrual reflects the total anticipated cost of completing these environmental remediation activities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Bloomfield Property In connection with the Company’s 2008 purchase of the portion of the Bloomfield campus that Kaman Aerospace Corporation had leased from NAVAIR, the Company assumed responsibility for environmental remediation at the facility as may be required under the Transfer Act and is currently remediating the property under the guidance of the Connecticut Department of Environmental Protection ("CTDEP"). The assumed environmental liability of $10.3 million was determined by taking the undiscounted estimated remediation liability of $20.8 million and discounting it at a rate of 8% . This remediation process will take many years to complete. The total amount paid to date in connection with these environmental remediation activities is $14.0 million . At June 28, 2019 , the Company had $2.2 million accrued for these environmental remediation activities. A portion ( $0.3 million ) of the accrual related to this property is included in other current liabilities, and the balance is included in other long-term liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. 14. COMMITMENTS AND CONTINGENCIES (CONTINUED) Rimpar Property In connection with the Company's purchase of GRW, the Company assumed responsibility for the environmental remediation at the Rimpar, Germany facility. In 2016, the Company completed an assessment which determined the estimated remediation liability was $0.5 million . The total amount paid to date in connection with these environmental remediation activities is $0.2 million . The balance ( $0.3 million ) of the accrual related to this property is included in other current liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Aerospace Claim Matter In October 2017, the Company received a letter from its customer seeking to recover $12.4 million associated with the rework of certain aerostructures components previously delivered by the Company and related costs incurred by the customer; however, the Company estimated the cost to rework these aerostructure components was $0.2 million . During April 2019, the Company and the customer reached an agreement to settle the matter for $0.2 million , which was paid subsequent to the second quarter of 2019. Offset Agreement During January 2018, the Company entered into an offset agreement as a condition to obtaining orders from a foreign customer for the Company's JPF product. This agreement is designed to return economic value to the foreign country by requiring the Company to engage in activities supporting local defense or commercial industries, promoting a balance of trade, developing in-country technology capabilities or addressing other local development priorities. The offset agreement may be satisfied through activities that do not require a direct cash payment, including transferring technology, providing manufacturing, training and other consulting support to in-country projects and the purchase by third parties of supplies from in-country vendors. This agreement may also be satisfied through the Company's use of cash for activities, such as subcontracting with local partners, purchasing supplies from in-country vendors, providing financial support for in-country projects and making investments in local ventures. At June 28, 2019 , the offset agreement had an outstanding notional value of approximately $194.0 million , which is equal to sixty percent of the contract value of $324.0 million as defined by the agreement between the customer and the Company. The amount ultimately applied against the offset agreement is based on negotiations with the customer and may require cash outlays that represent only a fraction of the notional value in the offset agreement. The Company continues to work with the customer to further define the requirements to satisfy the offset agreement. The satisfaction of the offset requirements will be determined by the customer and is expected to occur over a seven-year period. In the event the offset requirements of the contract are not met, the Company could be liable for potential penalties up to $16.5 million payable to the customer. The Company has not recognized any revenue associated with this contract and has considered the potential penalties of $16.5 million as a reduction to the transaction price in its determination of the value of the remaining performance obligations within this contract. Employee-Related Tax Matter During 2018, the Company identified certain individuals at one of its foreign subsidiaries who were potentially misclassified as self-employed persons performing services for the subsidiary, as opposed to being classified as employees of the subsidiary. The Company investigated the misclassification of these individuals and the potential liability for any associated social contributions, interest and fines and/or penalties as a result of the misclassification. Following the internal investigation, the foreign subsidiary made a voluntary disclosure of the matter to the appropriate legal and regulatory authorities. The Company has accrued $2.5 million , which represents the Company's best estimate of potentially unpaid social security contributions, related interest and possible penalties. There can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on the Company's results of operations, financial position and cash flows.

Some the Company's lease obligations have rent escalations or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. The terms for most machinery and equipment leases range from 3 to 5 years.

Earnings Per Share Reconciliation [Abstract]
Computation of Earnings Per Share	COMPUTATION OF EARNINGS PER SHARE The computation of basic earnings per share is based on net earnings divided by the weighted average number of shares of common stock outstanding for each period. The computation of diluted earnings per share reflects the common stock equivalency of dilutive options granted to employees under the Company's stock incentive plan, shares issuable on redemption of its convertible notes and shares issuable upon redemption of outstanding warrants. For the Three Months Ended For the Six Months Ended June 28, June 29, June 28, June 29, In thousands, except per share amounts Earnings from continuing operations $ 6,389 $ 4,778 $ 12,211 $ 9,748 Earnings from discontinued operations, net of tax 7,077 10,316 15,380 19,412 Net earnings $ 13,466 $ 15,094 $ 27,591 $ 29,160 Basic: Weighted average number of shares outstanding 27,961 27,971 27,935 27,911 Earnings per share from continuing operations $ 0.23 $ 0.17 $ 0.44 $ 0.35 Earnings per share from discontinued operations 0.25 0.37 0.55 0.69 Basic earnings per share $ 0.48 $ 0.54 $ 0.99 $ 1.04 Diluted: Weighted average number of shares outstanding 27,961 27,971 27,935 27,911 Weighted average shares issuable on exercise of dilutive stock options 162 237 162 228 Weighted average shares issuable on exercise of convertible notes — 108 — 54 Weighted average shares issuable on redemption of warrants related to the 2017 Notes — 33 — 65 Total 28,123 28,349 28,097 28,258 Earnings per share from continuing operations $ 0.23 $ 0.17 $ 0.43 $ 0.34 Earnings per share from discontinued operations 0.25 0.36 0.55 0.69 Diluted earnings per share $ 0.48 $ 0.53 $ 0.98 $ 1.03 Equity awards For the three-month and six-month fiscal periods ended June 28, 2019 , respectively, 374,660 and 379,946 shares issuable under equity awards granted to employees were excluded from the calculation of diluted earnings per share as they were anti-dilutive based on the average stock price during the period. For the three-month and six-month fiscal periods ended June 29, 2018 , respectively, 182,040 and 190,775 shares issuable under equity awards granted to employees were excluded from the calculation of diluted earnings per share as they were anti-dilutive based on the average stock price during the period. 2024 Convertible Notes For the three-month and six-month fiscal periods ended June 28, 2019 and June 29, 2018 , shares issuable under the Convertible Notes due 2024 were excluded from the diluted earnings per share calculation because the conversion price was more than the average market price of the Company's stock during the periods. Warrants For the six-month fiscal period ended June 29, 2018 , shares issuable under the warrants issued in connection with the Company's 2017 Notes were included in the calculation for diluted earnings per share as the strike price of the warrants was less than the average price of the Company's stock.

Share-based Arrangements

Share-based Compensation [Abstract]
Share-based Arrangements	SHARE-BASED ARRANGEMENTS The Company accounts for stock options, restricted stock awards, restricted stock units and performance shares as equity awards and measures the cost of all share-based payments, including stock options, at fair value on the grant date and recognizes this cost in the statement of operations. The Company also has an employee stock purchase plan which is accounted for as a liability award. Compensation expense for stock options, restricted stock awards and restricted stock units is recognized on a straight-line basis over the vesting period of the awards. Share-based compensation expense recorded for continuing operations for the three-month and six-month fiscal periods ended June 28, 2019 was $1.9 million and $3.5 million , respectively. Share-based compensation expense recorded for continuing operations for the three-month and six-month fiscal periods ended June 29, 2018 , was $2.0 million and $3.3 million , respectively. These amounts were included in selling, general and administrative expense on the Company's Condensed Statement of Operations. Share-based compensation expense recorded for discontinued operations for the three-month fiscal period ended June 28, 2019 was not material. Share-based compensation expense recorded for discontinued operations for the six-month fiscal period ended June 28, 2019 was $0.3 million . Share-based compensation expense recorded for discontinued operations for the three-month and six-month fiscal periods ended June 29, 2018 , was $0.3 million and $0.5 million , respectively. These amounts were included in earnings from discontinued operations, net of tax on the Company's Condensed Statement of Operations. As a result of the Company entering into a definitive agreement to sell its Distribution segment and the closing of the sale being considered probable, the vesting dates of all outstanding unvested stock options and restricted stock awards for certain Distribution employees were accelerated to vest on the anticipated closing date. Most of these stock options and awards would not have vested prior to the closing date; therefore, the related stock-based compensation expense previously recognized through the modification date was reduced to zero and a new fair value of the options and awards was established on the date the Company entered into the definitive agreement. The expense will be recognized ratably from the date of signing the definitive agreement to the anticipated closing date of the sale. While the acceleration of these awards is subject to Board of Directors approval, the Company estimates $2.8 million in incremental stock-based compensation to be recorded in 2019 in earnings from discontinued operations due to the acceleration of vesting. Of this amount, $0.2 million was recorded in the three-month fiscal period ended June 28, 2019 . From time-to-time, the Company has issued stock awards with market and performance based conditions. Throughout the course of the requisite service period, the Company monitors the level of achievement compared to the target and adjusts the number of shares expected to be earned, and the related compensation expense recorded thereafter, to reflect the most probable outcome. The number of shares earned under an award granted in 2016 has been determined at a 130% achievement level, representing 925 shares delivered in 2019. The number of shares earned were pro-rated to reflect the number of days the participant was employed by the Company during the performance period. There are no outstanding awards with these conditions that have not been settled. Compensation expense for these awards for the three-month and six-month fiscal periods ended June 28, 2019 , and June 29, 2018 , was not material. Stock option activity was as follows: For the Three Months Ended For the Six Months Ended June 28, 2019 June 28, 2019 Options Weighted - average exercise price Options Weighted - average exercise price Options outstanding at beginning of period 1,097,087 $ 49.04 935,252 $ 45.91 Granted — $ — 194,470 $ 61.02 Exercised (33,417 ) $ 38.43 (63,139 ) $ 33.38 Forfeited or expired (15,040 ) $ 57.30 (17,953 ) $ 58.01 Options outstanding at June 28, 2019 1,048,630 $ 49.26 1,048,630 $ 49.26 17.

Segment Reporting [Abstract]
Segment and Geographic Information	SEGMENT AND GEOGRAPHIC INFORMATION The Company is organized based upon the nature of its products and services, and is composed of two operating segments each overseen by a segment manager. These segments are reflective of how the Company’s Chief Executive Officer, who is its Chief Operating Decision Maker (“CODM”), reviews operating results for the purposes of allocating resources and assessing performance. The Company has not aggregated operating segments for purposes of identifying reportable segments. The Aerospace segment produces and markets proprietary aircraft bearings and components; super precision, miniature ball bearings for the medical, industrial and aerospace markets; complex metallic and composite aerostructures for commercial, military and general aviation fixed and rotary wing aircraft; and safe and arming solutions for missile and bomb systems for the U.S. and allied militaries. The segment also markets the design and supply of aftermarket parts to businesses performing maintenance, repair and overhaul ("MRO") in aerospace markets; performs helicopter subcontract work; restores, modifies and supports the Company's SH-2G Super Seasprite maritime helicopters; and manufactures and supports the Company's K-MAX® manned and unmanned medium-to-heavy lift helicopters. The Distribution segment is a leading power transmission, automation and fluid power industrial distributor with operations throughout the United States. The segment provides electro-mechanical products, bearings, power transmission, motion control and electrical and fluid power components, along with engineered integrated solutions for its customers' most challenging applications serving a broad spectrum of industrial markets, including both MRO and original equipment manufacturer ("OEM") customers. In the second quarter of 2019, the Company entered into a definitive agreement to sell its Distribution segment to affiliates of Littlejohn & Co., LLC; therefore, results for the Distribution segment were included in earnings from discontinued operations. 18.

SEGMENT AND GEOGRAPHIC INFORMATION (CONTINUED) Disaggregation of Revenue - continued The following table illustrates the approximate percentage of revenue recognized for performance obligations satisfied over time versus the amount of revenue recognized for performance obligations satisfied at a point in time for the Aerospace segment: For the Three Months Ended For the Six Months Ended In thousands June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Revenue recognized for performance obligations satisfied: Over time 50 % 48 % 47 % 50 % Point-in-time 50 % 52 % 53 % 50 % Total revenue 100 % 100 % 100 % 100 % For contracts that recognize revenue over time, the Company performs detailed quarterly reviews of the progress and execution of its performance obligations under these contracts. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the schedule (e.g. the number and type of milestone events), technical requirements (e.g., a newly-developed product versus a mature product) and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation (e.g. to estimate increases in wages and prices for materials and related support cost allocations), execution by subcontractors, the availability and timing of funding from customers and overhead cost rates, among other variables. Based upon these reviews, the Company will record the effects of adjustments in profit estimates each period. If at any time management determines that in the case of a particular contract total costs will exceed total contract revenue, a provision for the entire anticipated contract loss is recorded at that time. The amount of revenue recognized in the three-month fiscal period ended June 28, 2019 from performance obligations satisfied (or partially satisfied) in previous periods was $0.5 million . This amount was primarily related to favorable cost performance on the JPF contract with the USG, partially offset by cost growth on certain legacy fuzing contracts and the the SH-2G contract with Peru. The Company recognized a reduction in revenue of $0.3 million in the six-month fiscal period ended June 28, 2019 . This amount was primarily related to cost growth on the SH-2G program with Peru, certain legacy fuzing contracts, and a certain metallics structures contract, partially offset by favorable cost performance on certain Aerospace contracts, more specifically the JPF contract with the USG and the FMU-139 fuzing contract. The amount of revenue recognized in the three-month and six-month fiscal periods ended June 29, 2018 from performance obligations satisfied (or partially satisfied) in previous periods was $1.4 million and $3.0 million , respectively. These amounts were primarily related to changes in the estimates of the stage of completion of Aerospace contracts, more specifically the JPF contract with the USG, the AH-1Z contract and the SH-2G contract with Peru.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For the Three Months Ended For the Six Months Ended June 28, June 29, June 28, June 29, Effective Income Tax Rate from continuing operations (8.3 )% 2.5 % 7.2 % 15.7 % The effective income tax rate represents the combined federal, state and foreign tax effects attributable to pretax earnings from continuing operations for the period. The decrease in the effective tax rate from continuing operations for the three-month and six-month fiscal periods ended June 28, 2019 , compared to the corresponding rates in the prior year was primarily due to the partial reversal of valuation allowances which had been recorded against deferred tax assets related to state net operating loss carryforwards. The reversal was caused by a legislative change which made it more likely than not that more of the benefits from the loss carryforwards will be realized. A valuation allowance for deferred tax assets, including those associated with net operating loss carryforwards, is recognized when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. To assess that likelihood, the Company uses estimates and judgment regarding future taxable income, and considers the tax consequences in the jurisdiction where such taxable income is generated, to determine whether a valuation allowance is required. Such evidence can include current financial position, results of operations, both actual and forecasted, the reversal of deferred tax liabilities, and tax planning strategies, as well as the current and forecasted business economics. 20. INCOME TAXES (CONTINUED) The Company has assessed both positive and negative evidence to estimate whether sufficient future taxable income will be generated to utilize the $47.3 million of deferred tax assets recorded as of June 28, 2019 . Through the end of the second quarter of 2019, the Company believes it is more likely than not that only $39.8 million of these deferred tax assets will be realized and, as such, has recorded a valuation allowance of $7.5 million . Going forward, management will continue to assess the available positive and negative evidence to determine whether it is likely sufficient future taxable income will be generated to permit the use of these deferred tax assets. The amount of the deferred tax asset considered realizable could be adjusted if estimates of future taxable income are reduced or increased, or if additional weight is given to subjective evidence such as future expected growth because objective negative evidence in the form of cumulative losses is no longer present.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On July 15, 2019, the Company and U.S. Bank National Association, as trustee, entered into a first supplemental indenture (the “Supplemental Indenture”) to the Indenture, dated May 12, 2017 (as amended by the Supplemental Indenture, the “Indenture”), governing the Company’s 3.25% Convertible Senior Notes due 2024. The Supplemental Indenture expressly provides that the sale of the Company’s Distribution Segment will not violate the terms and provisions of the Indenture. The Supplemental Indenture became effective upon execution thereof, but the amendments embodied therein will not become operative until payment of the applicable consent fee, which is expected to occur on the date on which the sale transaction is consummated. On July 24, 2019, the Company entered into Amendment No. 4 to the Amended and Restated Credit Agreement, dated as of May 6, 2015, by and among the Company, the subsidiary borrowers from time to time party thereto, the Lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, Bank of America, N.A. and Citizens Bank, N.A., as Co-Syndication Agents, and SunTrust Bank, KeyBank National Association, TD Bank, N.A., Branch Banking and Trust Company and Fifth Third Bank, as Co-Documentation Agents (as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4 thereto, the “Credit Agreement”), to permit the sale of the Company’s Distribution Segment under the Credit Agreement and to provide for the release of certain subsidiary guarantees and collateral in connection therewith upon the closing of the sale transaction. The Company has evaluated subsequent events through the issuance date of these financial statements. Other than the matters noted above, no material subsequent events were identified that require disclosure.

Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION During the second quarter, Kaman Corporation and subsidiaries (collectively "the Company") announced an agreement to sell Kaman Industrial Technologies Corporation and its subsidiaries (the "Distribution segment") to affiliates of Littlejohn & Co., LLC for $700.0 million in cash, subject to customary closing conditions and working capital adjustments. As a result of the agreement, the Distribution segment met "held for sale" criteria in the fiscal quarter ended June 28, 2019. The Distribution segment's results of operations and the related cash flows from this business have been reclassified to earnings from discontinued operations in the Condensed Consolidated Statement of Operations and cash flows from discontinued operations in the Condensed Consolidated Statement of Cash Flows, respectively, for all periods presented. The assets and liabilities of the Distribution segment have been reclassified to assets held for sale and liabilities held for sale, respectively, in the Condensed Consolidated Balance Sheets as of June 28, 2019 and December 31, 2018. The sale is expected to close during the third quarter of 2019, subject to customary closing conditions and the receipt of certain required consents and approvals. See Note 4, Discontinued Operations , to the Condensed Consolidated Financial Statements for further information. In the opinion of management, the condensed consolidated financial information reflects all adjustments necessary for a fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented, but do not include all disclosures required by accounting principles generally accepted in the United States of America ("US GAAP"). All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . The results of operations for the interim periods presented are not necessarily indicative of trends or of results to be expected for the entire year. The Company has a calendar year-end; however, its first three fiscal quarters follow a 13-week convention, with each quarter ending on a Friday. The second quarters for 2019 and 2018 ended on June 28, 2019 , and June 29, 2018 , respectively.
Recent Accounting Standards	RECENT ACCOUNTING STANDARDS Recent Accounting Standards Adopted In February 2018, the FASB issued ASU 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income". The objective of this standard is to address the concern that tax effects of items within accumulated other comprehensive income do not appropriately reflect the tax rate because the Tax Cut and Jobs Act of 2017 ("Tax Reform") required the adjustment of deferred taxes be recorded to income. This ASU provides an entity the election to reclassify stranded tax effects resulting from Tax Reform to retained earnings from accumulated other comprehensive income. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The adoption of ASU 2018-02 resulted in an increase to retained earnings of $23.1 million , primarily related to the stranded tax effects resulting from Tax Reform for pension and other post-retirement benefits. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities". The objective of this standard update is to improve the financial reporting of hedging relationships to better reflect the economic results of an entity's risk management activities in its financial statements. This ASU expands hedge accounting for both nonfinancial and financial risk components and refines the measurement of hedge results to better reflect an entity's hedging strategies. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Adopted - continued In October 2018, the FASB issued ASU 2018-16, "Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes". The Federal Reserve Board and the Federal Reserve Bank of New York initiated an effort to introduce an alternative reference rate to LIBOR in the United States. This standard update permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption was permitted. The amendments in this ASU were required to be adopted concurrently with the amendments in ASU 2017-12. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Under this ASU as amended, lessees are required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged under this ASU as amended. This standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. On January 1, 2019, the Company adopted ASC 842 using the modified retrospective transition method allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result, the Company applied ASC 842 only to leases that existed as of January 1, 2019 and did not restate prior periods. The adoption of ASC 842 resulted in a net increase of approximately $90.0 million to its assets and liabilities as of January 1, 2019 due to the addition of right-of-use assets and lease liabilities for operating leases on the balance sheet; however, it did not have a material impact on the Company's cash flows, results of operations or debt covenant compliance. The majority of the right-of-use assets and lease liabilities recorded on January 1, 2019 for operating leases relate to the Distribution segment and were included in assets held for sale and liabilities held for sale, respectively, on the Company's Condensed Consolidated Balance Sheet as of June 28, 2019 . The Company has elected the following practical expedients (which must be elected as a package and applied consistently to all leases): an entity need not reassess whether any expired or existing contracts are or contain leases, an entity need not reassess the lease classification for any expired or existing leases and an entity need not reassess initial direct costs for any existing leases. Additionally, the Company has elected the practical expedient to not separate nonlease components from the associated lease component and account for those components as a single component for real estate leases. Nonlease components for the Company's vehicle and other equipment leases are not material. The Company has elected not to apply the recognition requirements to short-term leases, and will recognize the lease payments in profit or loss on a straight-line basis over the lease term and variable payments in the period in which the obligation for those payments is incurred. Subsequent to the issuance of ASU 2016-02, the FASB has issued the following updates: ASU 2018-10, "Codification Improvements to Topic 842, Leases", ASU 2018-11, "Leases (Topic 842): Targeted Improvements - Transition - Comparative Reporting at Adoption" and ASU 2019-01, "Leases (Topic 842): Codification Improvements". The amendments in these updates affect the guidance contained within ASU 2016-02 and were similarly adopted on January 1, 2019. See Note 3, Significant Accounting Policies Update , for further information on the impact of these standard updates. Recent Accounting Standards Yet to be Adopted In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses". The amendment clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 and impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Yet to be Adopted - continued In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". The objective of the standard update is to provide additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract to address the diversity in practice. The ASU requires an entity in a hosting arrangement that is a service arrangement to determine which costs to capitalize as an asset related to a service contract and which costs to expense, and to determine which project stage implementation activities relate to. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and postimplementation stages are expensed as the activities are performed. Capitalized implementation costs of a hosting arrangement are expensed over the term of the hosting arrangement in the same line item in the statement of operations as the fees associated with the hosting element of the arrangement. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. The amendments in this standard update should be applied either retrospectively or prospectively to all implementation costs incurred after the inception date. The Company has elected to adopt the standard update prospectively. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Disclosure Framework - Changes to Disclosure Requirements for Defined Benefit Plans". The objective of the standard update is to improve the effectiveness of disclosure requirements for defined benefit pension and other postretirement plans. This standard update removes disclosures that are no longer considered cost beneficial, clarifies specific requirements of disclosures and adds new disclosure requirements identified as relevant. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020. Early adoption is permitted. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurement". The objective of this standard update is to improve the effectiveness of disclosures for recurring and nonrecurring fair value measurements. This standard update removes certain disclosure requirements that are no longer considered cost beneficial, modifies existing disclosure requirements and adds new disclosure requirements identified as relevant. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of the ASU and delay adoption of the additional disclosures until the effective date. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The objective of this standard update is to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Under this ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. The standard update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The impact of the adoption of this standard update is dependent on the Company's goodwill impairment assessment. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". The objective of this standard update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted. An entity will apply the amendments in this ASU through a cumulative-effect adjustment to retained earnings as of the first reporting period in which the guidance is effective. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Yet to be Adopted - continued Subsequent to the issuance of ASU 2016-13, the FASB has issued the following updates: ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments- Credit Losses", ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments" and ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326) - Targeted Transition Relief". The amendments in these updates affect the guidance within ASU 2016-13 and have been assessed with ASU 2016-13.
Lessee, Leases [Policy Text Block]	3. SIGNIFICANT ACCOUNTING POLICIES UPDATE The Company's significant accounting policies are detailed in Note 1, Summary of Significant Accounting Policies of its Annual Report on Form 10-K for the year-ended December 31, 2018. Significant changes to our accounting policies as a result of adopting new accounting standards are discussed below: Leasing Under Accounting Standards Codification ("ASC") 842, the Company determines if a contract contains a lease at the inception date of the contract. To determine if the contract contains a lease, the Company evaluates if there is an identified asset in the contract and if the Company has control over the use of the identified asset. There is an identified asset in the contract if the asset is explicitly or implicitly specified in the contract, the asset is physically distinct or the Company has the right to receive substantially all of the asset's capacity, and if the supplier does not have substantive substitution rights. The Company has control over the use of the identified asset if the Company obtains substantially all economic benefits from the use of the asset and can direct the use of the asset. The Company applied the practical expedient for any contracts that existed prior to January 1, 2019; therefore, the contracts were not reassessed to determine if they contain leases. The Company must classify each lease as a finance lease or operating lease. A lease is classified as a finance lease if the Company will own the asset by the end of the lease term, the Company is reasonably certain to exercise the purchase option, the lease term covers a major part of the asset's economic life, the sum of the present value of the lease payments and the present value of the residual value guarantee not included in the lease payments equal or exceed substantially all of the fair value of the underlying asset at lease commencement or if the lessor has no alternative use for the asset. If any of these criteria are not met, the lease is classified as an operating lease. The Company applied the practical expedient for any leases that existed prior to January 1, 2019; therefore, the lease classifications of existing leases were not reassessed (all existing leases classified as operating leases under ASC 840 were classified as operating leases under ASC 842 on January 1, 2019 and all existing leases classified as capital leases under ASC 840 were classified as finance leases under ASC 842 on January 1, 2019). The Company's operating leases consist of rent commitments under various leases for office space, warehouses, land and buildings at varying dates from January 2019 to December 2024. The terms of most of these leases are in the range of 3 to 7 years, with certain leases renewable for varying periods and certain leases including options to terminate the leases. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so. It is expected that in the normal course of business leases that expire will be renewed or replaced by leases on other similar property. Some of the Company's leases have fixed amount rent escalations or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. The terms for most machinery and equipment leases range from 3 to 5 years. The majority of the Company's finance leases consist of assets purchased under the Company's master leasing agreement with PNC Equipment Finance ("PNC"), and are included in machinery, office furniture and equipment and construction in process. At June 28, 2019 , the Company's master leasing agreement with PNC had a maximum capacity of $20.0 million . The terms of these leases are 5 years. Amortization of these assets is included in depreciation and amortization expense. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued At the commencement date, the right-of-use asset and lease liability are recorded to the Company's Condensed Consolidated Balance Sheets when the Company obtains control of the use of the asset. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments upon entering into a lease agreement. The initial measurement of the lease liability is equal to the present value of the unpaid lease payments. Subsequent to the initial measurement, the lease liability continues to be measured at the present value of unpaid lease payments throughout the lease term. The lease liability is remeasured if the lease is modified and the modification is not accounted for as a separate contract, there is a change in the assessment of the lease term, the assessment of a purchase option exercise or the amount probable of being owed under a residual value guarantee, or a contingency is resolved resulting in some or all of the variable lease payments becoming fixed payments. The initial measurement of the right-of-use asset is equal to the total of the initial measurement of the lease liability, incremental costs to obtain the lease and prepaid lease payments, less any lease incentives received. Subsequent to the initial measurement, the right-of-use asset for a finance lease is equivalent to the initial measurement less accumulated amortization and any accumulated impairment losses. Generally, amortization of finance leases is recorded to cost of sales on a straight-line basis over the lease term. Subsequent to initial measurement, the right-of-use asset for an operating lease is equivalent to initial measurement less accumulated amortization (the difference between the straight-line lease cost for the period and the accretion of the lease liability using the effective interest method). The Company has elected not to apply the recognition requirements of ASC 842 to short-term leases (leases that, at the commencement date, have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise) as permissible under the standard. For short-term leases, the Company recognizes lease payments on a straight-line basis and variable payments in the period in which the obligation for those payments is incurred. Leasing contracts can be separated into lease components, non-lease components and items that are not components of the contract (items that do not transfer a good or service to the Company). Two or more contracts may be combined if at least one of which is or contains a lease entered into or near the same time with the same counterparty and consider the contracts as a single transaction if the contracts are negotiated as a package with the same objective, the amount of consideration to be paid in one contract depends on the price of performance of the other contract or the rights to use the underlying assets conveyed in the contracts are a single lease component. Lease components are considered separate if the Company can benefit from the right to use either on its own or together with other resources readily available to the Company and the right to use is not highly dependent or highly interrelated with the other rights to use the underlying assets in the contract. Consideration in the contract is allocated only to lease and non-lease components of a contract. The Company has elected the practical expedient allowing the Company to combine lease and non-lease components by class as a single lease component for its real estate leases. Nonlease components for the Company's vehicles and other equipment leases are not material. The lease term is the noncancellable period for which a lessee has the right to use an underlying asset, including periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. For renewal options, the Company performs an assessment at commencement if it is reasonably likely to exercise the option. The assessment is based on the Company's intentions, past practices, estimates and factors that create an economic incentive for the Company. Generally, the Company is not reasonably certain to exercise the renewal option in a lease contract as it performs an assessment for most real estate leases within six months prior to termination comparing the renewal rents under the option with the fair market returns for equivalent property under similar terms and conditions. Although the Company does not historically change locations often, it is not reasonably certain the Company will exercise the renewal option; therefore, the periods covered by the renewal option are not typically included in the lease term at commencement. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so; therefore, the Company does not typically consider the termination option in its lease term at commencement. Consideration in the contract is the sum of lease payments relating to the use of the underlying asset, fixed payments and other in-substance fixed payments, less any incentives received. Remeasurement of variable lease payments based on an index is only required if remeasurement is required for another reason, such as a change in lease term or change in estimates of probable payments under residual value guarantees. If remeasured, the remeasurement date becomes the new date for updating the payments based on the index. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued The Company uses the discount rate implicit in a lease contract, if available. As most of the Company's leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. For any leases that existed prior to the adoption of the standard, the Company used the incremental borrowing rate as of January 1, 2019 based on the type of asset and term of the lease. The Company separated its real estate leases by classes of lease terms and used the incremental borrowing rate consistent with its lease term class to determine the present value of lease payments. As most of the Company's vehicles have a four-year lease term, the Company used the incremental borrowing rate consistent with a four-year lease term for all vehicles. For all other equipment leases, the Company used the incremental borrowing rate consistent with a five-year lease term as the majority of the Company's leases for other equipment have a five-year lease term.
