Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies All references to the “Company” and “Kratos” refer to Kratos Defense & Security Solutions, Inc., a Delaware corporation, and its subsidiaries. (a) Basis of Presentation The information as of March 27, 2016 and for the three months ended March 27, 2016 and March 29, 2015 is unaudited. The condensed consolidated balance sheet as of December 27, 2015 was derived from the Company’s audited consolidated financial statements at that date. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results have been prepared in accordance with the instructions to Form 10-Q and do not necessarily include all information and footnotes necessary for presentation in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s audited annual consolidated financial statements for the fiscal year ended December 27, 2015 , included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 11, 2016 (the “Form 10-K”). Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole. As discussed in Note 2 - Discontinued Operations, the amounts related to the first quarter of fiscal 2015 in these condensed consolidated financial statements have been recast to reflect the August 21, 2015 disposition of the Company’s 100% owned subsidiary Herley Industries, Inc. (“Herley”) and certain of Herley’s subsidiaries, including Herley-CTI, Inc., EW Simulation Technology, Ltd. and Stapor Research, Inc. (collectively, the “Herley Entities”) as discontinued operations. (b) Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its 100% owned subsidiaries for which all inter-company transactions have been eliminated in consolidation. (c) Fiscal Year The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year, with interim fiscal periods ending on the last Sunday of each calendar quarter. The three month periods ended March 27, 2016 and March 29, 2015 consisted of 13-week periods. There are 52 calendar weeks in the fiscal years ending on December 25, 2016 and December 27, 2015 . (d) Accounting Estimates There have been no significant changes in the Company’s accounting estimates for the three months ended March 27, 2016 as compared to the accounting estimates described in the Form 10-K. (e) Accounting Standards Updates In April 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2016-10 (“ASU 2016-10”), Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing . ASU 2016-10 provides additional guidance on identifying performance obligations and clarifies the implementation guidance on licensing. In March 2016, the FASB issued ASU 2016-08 (“ASU 2016-08”), Revenue from Contracts with Customers, Principal versus Agent Considerations. ASU 2016-08 clarifies the implementation guidance and illustrations in the new revenue standard. In August 2015, the FASB issued ASU 2015-14 (“ASU 2015-14”), Revenue from Contracts with Customers, Deferral of the Effective Date that deferred the effective date of ASU 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers. Pursuant to ASU 2015-14, public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The FASB issued ASU 2014-09 in May 2014. ASU 2014-09 affects any entity using GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards ( e.g ., insurance contracts or lease contracts). ASU 2014-09 will supersede the revenue recognition requirements in Topic 605, Revenue Recognition , and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in FASB Accounting Standards Codification (“ASC”) Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented or apply the requirements in the year of adoption, through a cumulative adjustment. The Company has not yet selected a transition method nor has it determined the impact of adoption on its condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases . ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes . The ASU eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments apply to all organizations that present a classified balance sheet. For public companies, the amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The FASB also decided to permit earlier application by all entities as of the beginning of any interim or annual reporting period. The amendment provides the reporting entity with an option to apply the amendment prospectively, or retrospectively to all prior periods presented in the financial statements. The Company adopted ASU 2015-17 prospectively for the fiscal year ended December 27, 2015. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting . ASU 2015-15 supplements the requirements of ASU 2015-03 by allowing an entity to defer and present debt issuance costs related to a line of credit arrangement as an asset and subsequently amortize the deferred costs ratably over the term of the line of credit arrangement. The Company adopted ASU 2015-15 for the fiscal year ended December 27, 2015. Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs . ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years and early adoption of the amendments is permitted for financial statements that have not been previously issued and should be applied on a retrospective basis. The Company adopted ASU 2015-03 for the fiscal year ended December 27, 2015 In January 2015, the FASB issued ASU 2015-01 (“ASU 2015-01”), Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company adopted this standard in the quarter ended March 27, 2016, which did not have a material impact on its condensed consolidated financial statements. In August 2014, the FASB issued ASU 2014-15 (“ASU 2014-15”), Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. Financial reporting under this presumption is commonly referred to as the going concern basis of accounting. The going concern basis of accounting is critical to financial reporting because it establishes the fundamental basis for measuring and classifying assets and liabilities. Currently, GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. ASU 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company does not believe that the adoption of this guidance will have a material impact on its condensed consolidated financial statements. There have been no changes in the Company’s significant accounting policies, other than the adoption of ASU 2015-01, for the three months ended March 27, 2016 as compared to the significant accounting policies described in the Form 10-K. (f) Fair Value of Financial Instruments The carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at March 27, 2016 and December 27, 2015 are presented in Note 8. The carrying value of all other financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued expenses, billings in excess of cost and earnings on uncompleted contracts, income taxes payable and short-term debt, approximated their estimated fair values at March 27, 2016 and December 27, 2015 due to the short-term nature of these instruments.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On August 21, 2015, the Company completed the sale of the U.S. and U.K. operations of its Electronic Products Division to Ultra Electronics Holdings plc (“Ultra”), a public limited company formed under the laws of England and Wales and traded on the London Stock Exchange, and Ultra Electronics Defense Inc. (the “Buyer”), a Delaware corporation ultimately owned by Ultra (the “Transaction”). Pursuant to the terms of that certain Stock Purchase Agreement, dated May 31, 2015, by and among the Company, Ultra and the Buyer (the “Purchase Agreement”), the Company sold to the Buyer all of the issued and outstanding capital stock of its wholly owned subsidiary Herley and the Herley Entities, for $260.0 million and $5.0 million for taxes incurred as part of the Transaction, less a $2.0 million escrow to satisfy any purchase price adjustments, and an estimated working capital adjustment of $8.3 million . The Purchase Agreement also contains certain non-compete and indemnification provisions. Under the Purchase Agreement, the Company entered into an agreement to indemnify the Buyer for any pre-acquisition tax liabilities. As a result of this arrangement, the Company recorded amounts that have historically been classified as unrecognized tax benefits into other long-term liabilities. The Company also agreed to indemnify Ultra for pre-existing environmental conditions for a period of five years from the closing date, with a maximum indemnification payment of $34.0 million . The Company does not believe payments will be required under the indemnification provision, and the assessment of the fair value is immaterial. Under the terms of the Purchase Agreement, a joint 338(h)(10) election has been made for income tax purposes, providing a “step up” in tax basis to Ultra. The Company incurred approximately $11.5 million in transaction-related costs. The gain on sale of $80.8 million is subject to changes in the indemnification obligations. In accordance with ASC 360-10-45-9, Property, Plant, and Equipment (Topic 360) and ASC 205-20-45-3 Presentation of Financial Statements (Topic 205), the Herley Entities were classified as discontinued operations in the accompanying condensed consolidated financial statements for all periods presented. Immediately prior to the closing of the Transaction, the outstanding shares of the capital stock of (i) General Microwave Corporation, a New York corporation, and its direct and indirect wholly owned subsidiaries General Microwave Israel Corporation, a Delaware corporation, General Microwave Israel (1987) Ltd., an Israeli company, and Herley GMI Eyal Ltd., an Israeli company, (ii) MSI Acquisition Corp., a Delaware corporation and its wholly owned subsidiary Micro Systems, Inc., a Florida corporation, and (iii) Herley-RSS, Inc., a Delaware corporation, were distributed as a dividend by Herley to the Company and will continue their current operations as wholly owned subsidiaries of the Company. In November 2015, the Company and Ultra settled the working capital adjustment at $8.1 million , and the net cash position at closing, resulting in a net payment to the Company of $2.7 million . This represents the payment from escrow to the Company of $2.0 million , as well as the payment from Ultra of $0.7 million , reflecting the difference in the estimated working capital and actual working capital and the net cash position at the close of the Transaction. In January 2016, Ultra reimbursed the Company the $5.0 million maximum for taxes incurred as part of the Transaction. The following table presents the results of discontinued operations (in millions): Three Months Ended March 27, 2016 March 29, 2015 Revenue $ — $ 25.5 Cost of sales — 16.9 Selling, general and administrative expenses — 6.1 Interest expense, net — 3.4 Other net expense items that are not major — 0.4 Loss from discontinued operations before income taxes — (1.3 ) Income tax expense — (0.4 ) Loss from discontinued operations $ — $ (1.7 ) Depreciation and amortization expense included in selling, general and administrative expenses was $1.7 million for the three months ended March 29, 2015 . Interest expense is included based on an allocation consistent with the redemption of $175.0 million of the Company’s 7% Senior Secured Notes due 2019 (the “Notes”) and the repayment of $41.0 million in outstanding borrowings on that certain Credit and Security Agreement, dated May 14, 2014 (the “Credit Agreement”), by and among the Company, the lenders from time to time party thereto, SunTrust Bank, as Agent (the “Agent”), PNC Bank, National Association, as Joint Lead Arranger and Documentation Agent, and SunTrust Robinson Humphrey, Inc., as Joint Leader Arranger and Sole Book Runner, that was repaid upon the completion of the sale of the Herley Entities in accordance with the terms and conditions of the Indenture (as defined below) and the Credit Agreement, respectively. Refer to Note 8 for further discussion. The following is a summary of the liabilities of discontinued operations in the accompanying condensed consolidated balance sheets as of March 27, 2016 and December 27, 2015 (in millions): March 27, December 27, Accrued compensation $ 0.8 $ 0.9 Other current liabilities 0.6 1.0 Current liabilities of discontinued operations $ 1.4 $ 1.9 Non-current liabilities of discontinued operations $ 3.9 $ 4.1

Under Topic 260, basic net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the reporting period. Diluted net loss per common share reflects the effects of potentially dilutive securities. Shares from stock options and awards, excluded from the calculation of diluted net loss per share because their inclusion would have been anti-dilutive, were 2.5 million and 2.3 million for the three months ended March 27, 2016 and March 29, 2015 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes A reconciliation of the income tax benefit from continuing operations computed by applying the statutory federal income tax rate of 35% to loss from continuing operations before income taxes to the income tax provision for the three months ended March 27, 2016 and March 29, 2015 was as follows (in millions): March 27, March 29, Income tax benefit at federal statutory rate $ (6.5 ) $ (4.4 ) State and foreign taxes, net of federal tax benefit and valuation allowance 0.4 0.4 Nondeductible expenses and other 0.4 0.3 Impact of deferred tax liabilities for indefinite-lived assets 1.5 1.5 Increase in reserves for uncertain tax positions 1.7 0.1 Increase in federal valuation allowance 6.1 4.0 Total income tax provision $ 3.6 $ 1.9 In assessing the Company’s ability to realize deferred tax assets, management considers, on a periodic basis, whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As such, management has determined that it is appropriate to maintain a full valuation allowance against the Company’s U.S. federal, combined state and certain foreign deferred tax assets, with the exception of an amount equal to its deferred tax liabilities, which can be expected to reverse over a definite life. Federal and state income tax laws impose restrictions on the utilization of net operating loss (“NOL”) and tax credit carryforwards in the event that an “ownership change” occurs for tax purposes, as defined by Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”). In general, an ownership change occurs when shareholders owning 5% or more of a “loss corporation” (a corporation entitled to use NOL or other loss carryovers) have increased their ownership of stock in such corporation by more than 50 percentage points during any three-year period. The annual base Section 382 limitation is calculated by multiplying the loss corporation’s value at the time of the ownership change by the greater of the long-term tax-exempt rate determined by the Internal Revenue Service in the month of the ownership change or the two preceding months. This base limitation is subject to adjustments, including an increase for built-in gains recognized in the five -year period after the ownership change. In March 2010, an “ownership change” occurred that will limit the utilization of NOL carryforwards. In July 2011, another “ownership change” occurred. The March 2010 ownership change limitation is more restrictive. In prior years, the Company acquired corporations with NOL carryforwards at the date of acquisition (“Acquired NOLs”). The Acquired NOLs are subject to separate limitations that may further restrict the use of Acquired NOLs. As a result, the Company’s federal annual utilization of NOL carryforwards were limited to at least $27.0 million a year for the five years succeeding the March 2010 ownership change and at least $11.6 million for each year thereafter subject to separate limitations for Acquired NOLs. If the entire limitation amount is not utilized in a year, the excess can be carried forward and utilized in future years. For the three months ended March 27, 2016 , there was no impact of such limitations on the income tax provision, since the amount of taxable income did not exceed the annual limitation amount. In addition, future equity offerings or acquisitions that have equity as a component of the purchase price could also cause an “ownership change.” If and when any other “ownership change” occurs, utilization of the NOL or other tax attributes may be further limited. As discussed elsewhere, deferred tax assets relating to the NOL and credit carryforwards are offset by a full valuation allowance. In addition, utilization of state tax loss carryforwards is dependent upon sufficient taxable income apportioned to the states. The Company is subject to taxation in the U.S. and various state and foreign tax jurisdictions. The Company’s tax years for 2000 and later are subject to examination by the U.S. and state tax authorities due to the existence of the NOL carryforwards. Generally, the Company’s tax years for 2002 and later are subject to examination by various foreign tax authorities. As of December 27, 2015 , the Company had $17.2 million of unrecognized tax benefits that, if recognized, would impact the effective income tax rate, subject to possible offset by an increase in the deferred tax asset valuation allowance. During the three months ended March 27, 2016 , unrecognized tax benefits were increased by $1.4 million relating to various current year and prior positions. In connection with the Company’s disposition of the Electronic Products Division, the Company entered into an agreement to indemnify the Buyer for any pre-acquisition tax liabilities. As a result of this arrangement, the Company recorded amounts that have historically been classified as unrecognized tax benefits into other long-term liabilities. The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. For the three months ended March 27, 2016 and March 29, 2015 , a $0.6 million expense and $0.1 million expense, respectively, were recorded related to interest and penalties. The Company believes that no significant amount of the liabilities for uncertain tax positions will expire within twelve months of March 27, 2016 .

Debt

Debt Disclosure [Abstract]
Debt	Debt (a) Issuance of 7.00% Senior Secured Notes due 2019 In May 2014, the Company refinanced its $625.0 million 10% Senior Secured Notes due in 2017 (the “ 10% Notes ”) with $625.0 million of newly issued Notes, as defined above. The net proceeds of the Notes was $618.5 million after an original issue discount of $6.5 million . The Company incurred debt issuance costs of $8.8 million associated with the new Notes. The Company utilized the net proceeds from the Notes, a $41.0 million draw on the Credit Agreement discussed below, as well as cash from operations to extinguish the 10% Notes . The total reacquisition price of the 10% Notes was $661.5 million including a $31.2 million early termination fee, the write-off of $15.5 million of unamortized issue costs, $12.9 million of unamortized premium, along with $5.3 million of additional interest while in escrow, which resulted in a loss on extinguishment of $39.1 million . The Company completed the offering of the Notes in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Act”). The Notes are governed by the Indenture, dated May 14, 2014 (the “Indenture”), among the Company, certain of the Company’s subsidiaries (the “Subsidiary Guarantors”) and Wilmington Trust, National Association, as Trustee and Collateral Agent. A Subsidiary Guarantor can be released from its Guarantee (as defined in the Indenture) if (a) all of the Capital Stock (as defined in the Indenture) issued by such Subsidiary Guarantor or all or substantially all of the assets of such Subsidiary Guarantor are sold or otherwise disposed of; (b) the Company designates such Subsidiary Guarantor as an Unrestricted Subsidiary (as defined in the Indenture); (c) if the Company exercises its legal defeasance option or its covenant defeasance option; or (d) upon satisfaction and discharge of the Indenture or payment in full in cash of the principal of, premium, if any, and accrued and unpaid interest. The holders of the Notes have a first priority lien on substantially all of the Company’s assets and the assets of the Subsidiary Guarantors, except with respect to accounts receivable, inventory, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property), on which the holders of the Notes have a second priority lien to the Company’s $110.0 million Credit Agreement. The Company pays interest on the Notes semi-annually, in arrears, on May 15 and November 15 of each year. The Notes include customary covenants and events of default as well as a consolidated fixed charge ratio of 2.0 :1 for the incurrence of additional indebtedness. Negative covenants include, among other things, limitations on additional debt, liens, negative pledges, investments, dividends, stock repurchases, asset sales and affiliate transactions. Events of default include, among other events, non-performance of covenants, breach of representations, cross-default to other material debt, bankruptcy, insolvency, material judgments and changes in control. As of March 27, 2016 , the Company was in compliance with the covenants contained in the Indenture governing the Notes. On or after May 15, 2016, the Company may redeem some or all of the Notes at 105.25% of the aggregate principal amount of such Notes through May 15, 2017, 102.625% of the aggregate principal amount of such Notes through May 15, 2018 and 100% of the aggregate principal amount of such Notes thereafter, plus accrued and unpaid interest to the date of redemption. In addition, the Company may redeem up to 35% of the Notes at 107% of the aggregate principal amount of such Notes plus accrued and unpaid interest before May 15, 2016 with the net proceeds of certain equity offerings. The Company may also redeem some or all of the Notes before May 15, 2016 at a redemption price of 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the redemption date, plus a “make whole” premium. In addition, at one time prior to May 15, 2016, the Company may redeem up to 10% of the original aggregate principal amount of the Notes issued under the Indenture at a redemption price of 103% of the principal amount thereof, plus accrued and unpaid interest to the date of redemption. On October 16, 2014, the Company exchanged the outstanding Notes for an equal amount of new Notes that have been registered under the Act. The terms of the Notes issued in the exchange offer are identical in all material respects to the terms of the Notes, except the Notes issued in the exchange offer have been registered under the Act. The terms of the Indenture require that the net cash proceeds from asset dispositions be either utilized to (i) repay or prepay amounts outstanding under the Company’s Indenture and Credit Agreement unless such amounts are reinvested in similar collateral, (ii) make an investment in assets that replace the collateral of the Notes or (iii) a combination of both (i) and (ii). To the extent there are any remaining net proceeds from the asset disposition after application of (i) and (ii), such amounts are required to be utilized to repurchase Notes at par after 360 days following the asset disposition. Following the sale of the Herley Entities (see Note 2 of these Notes to the Condensed Consolidated Financial Statements), the Company, on August 21, 2015, paid down the $41.0 million outstanding on the Company’s $110.0 million Credit Agreement and on September 22, 2015, repurchased $175.0 million of the Notes at par, in accordance with the Indenture. At March 27, 2016 , the Company has approximately $2.0 million to $4.0 million of estimated remaining net proceeds. The Company intends to invest the remaining proceeds in replacement collateral under the Indenture within the 360 days following the asset disposition. Related to the $175.0 million repurchase, the Company wrote off $1.8 million of unamortized issue costs, $1.4 million of unamortized discount, and incurred $0.2 million of legal fees, which resulted in a loss on extinguishment of debt of $3.4 million . As of March 27, 2016 , there was $450.0 million in Notes outstanding. (b) Other Indebtedness $110.0 Million Credit Agreement On May 14, 2014, the Company replaced its credit facility with KeyBank National Association and entered into the Credit Agreement. The Credit Agreement established a five -year senior secured revolving credit facility in the maximum amount of $110.0 million (subject to a potential increase of the maximum principal amount to $135.0 million , subject to the Agent’s and applicable lenders’ approval as described therein), consisting of a subline for letters of credit in an amount not to exceed $50.0 million , as well as a swingline loan in an aggregate principal amount at any time outstanding not to exceed $10.0 million . The Credit Agreement is secured by a lien on substantially all of the Company’s assets and the assets of the guarantors thereunder, subject to certain exceptions and permitted liens. The Credit Agreement has a first priority lien on accounts receivable, inventory, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property). On all other assets, the Credit Agreement has a second priority lien junior to the lien securing the Notes. The Credit Agreement contains certain covenants, which include, but are not limited to, restrictions on indebtedness, liens, and investments, and limits on other various payments, as well as a financial covenant relating to a minimum fixed charge coverage ratio of 1.15 :1. Events of default under the terms of the Credit Agreement include, but are not limited to: failure of the Company to pay any principal of any loans in full when due and payable; failure of the Company to pay any interest on any loan or any fee or other amount payable under the Credit Agreement within three business days after the date when due and payable; failure of the Company or any of its subsidiaries to comply with certain covenants and agreements, subject to applicable grace periods and/or notice requirements; or any representation, warranty or statement made in or pursuant to the Credit Agreement or any related writing or any other material information furnished by the Company or any of its subsidiaries to the Agent or the lenders shall prove to be false or erroneous; and the occurrence of an event or condition having or reasonably likely to have a material adverse effect, which includes a material adverse effect on the business, operations, condition (financial or otherwise) or prospects of the Company or the ability of the Company to repay its obligations. Where an event of default arises from certain bankruptcy events, the commitments shall automatically and immediately terminate and the principal of, and interest then outstanding on, all of the loans shall become immediately due and payable. Subject to certain notice requirements and other conditions, upon the occurrence of an event of default, including the occurrence of a condition having or reasonably likely to have a material adverse effect, commitments may be terminated and the principal of, and interest then outstanding on, all of the loans may become immediately due and payable. At March 27, 2016 , no event of default had occurred and the Company believed that events or conditions having a material adverse effect, giving rise to an acceleration of any amounts outstanding under the Credit Agreement, had not occurred and was remote. Borrowings under the revolving Credit Agreement may take the form of a base rate revolving loan, Eurodollar revolving loan or swingline loan. Base rate revolving loans and swingline loans will bear interest at a rate per annum equal to the sum of the applicable margin from time to time in effect plus the highest of (i) the Agent’s prime lending rate, as in effect at such time, (ii) the federal funds rate, as in effect at such time, plus 0.50% per annum, and (iii) the adjusted London Interbank Offered Rate (“LIBOR”) determined at such time for an interest period of one month, plus 1.00% per annum. Eurodollar revolving loans will bear interest at a rate per annum equal to the sum of the applicable margin from time to time in effect plus the adjusted LIBOR. The applicable margin varies between 1.50% - 2.00% for base rate revolving loans and swingline loans and 2.50% - 3.00% for Eurodollar loans, and is based on several factors including the Company’s then-existing borrowing base and the Lender’s total commitment amount and revolving credit exposure. The calculation of the Company’s borrowing base takes into account several items relating to the Company and its subsidiaries, including amounts due and owing under billed and unbilled accounts receivables, then-held eligible raw materials inventory, work-in-process inventory, and applicable reserves. On May 31, 2015, the Company entered into a third amendment (the “Third Amendment”) to the Credit Agreement. Under the terms of the Third Amendment, the definitions of certain terms of the Credit Agreement were modified, the disposition of the Herley Entities was approved by the lenders, a minimum $175.0 million repurchase of the Notes by the Company was required and the payment in full of the outstanding balance of the Credit Agreement was required upon consummation of the sale of the Herley Entities. Additionally, the measurement of the fixed charge coverage ratio of 1.15 :1 was modified as follows: (i) the fixed charge coverage ratio will not be measured as of the quarterly reporting period ending as of the end of any quarterly reporting period ending after June 30, 2015, if on such date (a) there are no outstanding revolving loans or swingline loans and (b) the aggregate amount outstanding under letters of credit is less than or equal to $17.0 million , and (ii) as to any subsequent quarterly reporting period ending after June 30, 2015, and not covered by (i) above, a fixed charge coverage ratio of at least 1.05 :1 will be applied if the percentage of (a) outstanding revolving loans plus the sum of the outstanding swingline loans and outstanding letters of credit that are in excess of $17.0 million , to (b) the revolving credit commitment, minus the Herley Disposition Proceeds Reinvestment Reserve, as defined below, is greater than 0.00% but less than 15.00% or a fixed charge coverage ratio of 1.10 :1 will be applied if the aforementioned percentage is equal to or greater than 15.00% but less than 25.00% . In all other instances, the fixed charge coverage ratio remains at 1.15 :1. For purposes of computing the fixed charge coverage ratio, the associated reduction in consolidated interest expense in connection with the repurchase of Notes with proceeds from the sale of the Herley Entities shall be deemed to have occurred on the first day of the most recently completed four quarterly reporting periods prior to the sale. The terms of the Third Amendment also included the establishment of a reserve (the “Herley Disposition Proceeds Reinvestment Reserve”) that reduced the maximum $110.0 million total borrowing base on the Credit Agreement. With the sale of the Herley Entities, a $50.8 million reserve was established based upon the collateral carrying value under the Credit Agreement of the Herley Entities disposed. The reserve and therefore the maximum borrowing base were adjusted monthly for the subsequent cumulative reinvestment in similar collateral assets over a period not to have exceeded 360 days from the sale of the Herley Entities. As of March 27, 2016 , there was no reserve on the maximum borrowings, resulting from a cumulative reinvestment in similar collateral assets since the sale of the Herley Entities in excess of the $50.8 million reserve established at the date of the sale of the Herley Entities. The Company made investments in assets that replaced the collateral, which has reinstated the maximum facility to the full $110.0 million as of the end of the first quarter of 2016. On August 19, 2015, the Company entered into a fourth amendment (the “Fourth Amendment”) to the Credit Agreement. Among other things, the Fourth Amendment provides for a modification of the Third Amendment as it relates to when the minimum fixed charge coverage ratio will be measured based upon the Company’s outstanding borrowings. Outstanding borrowings for purposes of computing the applicable minimum fixed charge coverage ratio exclude any letter of credit exposure outstanding of $17.0 million plus the amount of letters of credit outstanding for the divested Herley Entities for which a cash deposit has been placed in escrow by the Buyer to cover the amount of such outstanding letters of credit, should the letters of credit be pulled. As of March 27, 2016 , there were no borrowings outstanding on the Credit Agreement and $10.1 million outstanding on letters of credit, resulting in net borrowing base availability of $52.8 million . The Company was in compliance with the financial covenants of the Credit Agreement and its amendments as of March 27, 2016 . Debt Acquired in Acquisition The Company has a $10.0 million ten -year term loan with a bank in Israel entered into on September 16, 2008 in connection with the acquisition of one of its wholly owned subsidiaries. The balance as of March 27, 2016 was $2.5 million , and the loan is payable in quarterly installments of $0.3 million plus interest at LIBOR plus a margin of 1.5% . The loan agreement contains various covenants, including a minimum net equity covenant as defined in the loan agreement. The Company was in compliance with all covenants as of March 27, 2016 . Fair Value of Long-term Debt Carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at March 27, 2016 and December 27, 2015 are presented in the following table: As of March 27, 2016 As of December 27, 2015 $ in millions Principal Carrying Fair Value Principal Carrying Fair Value Total long-term debt including current portion $ 452.5 $ 445.4 $ 359.5 $ 452.7 $ 445.1 $ 315.2 The fair value of the Company’s long-term debt was based upon actual trading activity (Level 1, Observable inputs -quoted prices in active markets). As of March 27, 2016 , the difference between the carrying amount of $445.4 million and the principal amount of $452.5 million presented in the previous table is the net unamortized original issue discount of $3.1 million and the unamortized debt issuance costs of $4.0 million , which are being accreted to interest expense over the term of the related debt.

Segment Reporting [Abstract]
Segment Information	Segment Information The Kratos Government Solutions (“KGS”) reportable segment is comprised of an aggregation of KGS operating segments, including our microwave electronic products, satellite communications, modular systems and defense and rocket support operating segments. The Unmanned Systems (“US”) reportable segment consists of our unmanned aerial, ground, seaborne and command, control and communications system business. The KGS and US segments provide products, solutions and services for mission critical national security programs. KGS and US customers primarily include national security related agencies, the U.S. Department of Defense (the “DoD”), intelligence agencies and classified agencies, and to a lesser degree, international government agencies and domestic and international commercial customers. The Public Safety & Security (“PSS”) reportable segment designs, engineers, deploys, operates, integrates into command and control infrastructure, maintains and operates security and surveillance solutions for homeland security, public safety, critical infrastructure, government and commercial customers. PSS customers include those in the critical infrastructure, power generation, power transport, nuclear energy, financial, IT, healthcare, education, transportation and petro-chemical industries, as well as certain government and military customers. The Company organizes its reportable segments based on the nature of the products, solutions and services offered. Transactions between segments are generally negotiated and accounted for under terms and conditions similar to other government and commercial contracts. This presentation is consistent with the Company’s operating structure. In the following table total operating income (loss) from continuing operations of the reportable business segments is reconciled to the corresponding consolidated amount. The reconciling item “unallocated corporate expense, net” includes costs for certain stock-based compensation programs (including stock-based compensation costs for stock options, employee stock purchase plan and restricted stock units), the effects of items not considered part of management’s evaluation of segment operating performance, merger and acquisition expenses, corporate costs not allocated to the segments, and other miscellaneous corporate activities. As discussed in Note 2 - Discontinued Operations, the Company began reporting the Herley Entities as discontinued operations effective in the second quarter of fiscal 2015. Prior to the decision to sell the Herley Entities, the Company reported their financial results in the KGS reportable segment. Accordingly, segment results for the first quarter of fiscal 2015 have been recast to reflect the disposition of the Herley Entities as discontinued operations. As certain overhead type costs previously allocated to the Herley Entities are not allocable to discontinued operations, prior period corporate costs have been reallocated amongst the continuing reportable segments. During the three months ended March 27, 2016 , the PSS reportable segment recorded a $1.9 million charge related to a litigation settlement of a contract dispute and the KGS reportable segment recorded a $3.0 million impairment charge of the carrying value of inventories as a result of the decision to close one of its manufacturing facilities and the exit of certain lower margin product business lines. The Company expects to complete the restructuring and record any additional related charges in the second fiscal quarter. Revenues, depreciation and amortization, and operating income (loss) generated by the Company’s reportable segments for the three month periods ended March 27, 2016 and March 29, 2015 are as follows (in millions): Three Months Ended March 27, 2016 March 29, 2015 Revenues: Kratos Government Solutions Service revenues $ 52.4 $ 49.8 Product sales 56.2 57.4 Total Kratos Government Solutions 108.6 107.2 Public Safety & Security Service revenues 30.2 37.5 Product sales — — Total Public Safety & Security 30.2 37.5 Unmanned Systems Service revenues — — Product sales 14.2 12.4 Total Unmanned Systems 14.2 12.4 Total revenues $ 153.0 $ 157.1 Depreciation & amortization: Kratos Government Solutions $ 4.1 $ 5.1 Public Safety & Security 0.1 0.2 Unmanned Systems 1.9 1.6 Total depreciation and amortization $ 6.1 $ 6.9 Operating income (loss) from continuing operations: Kratos Government Solutions $ (1.8 ) $ 2.4 Public Safety & Security (2.7 ) — Unmanned Systems (4.2 ) (4.2 ) Unallocated corporate expense, net (1.5 ) (2.1 ) Total operating loss from continuing operations $ (10.2 ) $ (3.9 )

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In addition to commitments and obligations in the ordinary course of business, the Company is subject to various claims, pending and potential legal actions for damages, investigations relating to governmental laws and regulations and other matters arising out of the normal conduct of the Company’s business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its condensed consolidated financial statements. An estimated loss contingency is accrued in the Company’s condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including but not limited to the procedural status of the matter in question, the presence of complex or novel legal theories, and the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes and, as such, are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. The amount of ultimate loss may differ from these estimates. It is possible that cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies. Whether any losses finally determined in any claim, action, investigation or proceeding could reasonably have a material effect on the Company’s business, financial condition, results of operations or cash flows will depend on a number of variables, including the timing and amount of such losses; the structure and type of any remedies; the monetary significance any such losses, damages or remedies may have on the Company’s condensed consolidated financial statements; and the unique facts and circumstances of the particular matter that may give rise to additional factors. Legal and Regulatory Matters U.S. Government Cost Claims. The Company’s contracts with the DoD are subject to audit by the Defense Contract Audit Agency (“DCAA”). As a result of these audits, from time to time the Company is advised of claims concerning potential disallowed, overstated or disputed costs. For example, during the course of recent audits of the Company’s contracts, the DCAA is closely examining and questioning certain of the established and disclosed practices that it had previously audited and accepted. The Company’s personnel regularly scrutinizes costs incurred and allocated to contracts with the U.S. Government for compliance with regulatory standards. On July 28, 2015, the Company received a determination letter from the Defense Contract Management Agency (“DCMA”) regarding what the DCMA believed were certain unallowable costs for one of the Company’s subsidiaries with respect to fiscal year 2007. In April 2016, the Company reached agreement with the DCAA to settle matters related to unallowable costs for this subsidiary for fiscal years 2007 and 2008 for approximately $0.2 million . For those Company subsidiaries and fiscal years which have not yet been audited by the DCAA or for those audits which are in process which have not been completed by the DCAA, the Company cannot reasonably estimate the range of loss, if any, that may result from audits and reviews in which it is currently involved given the inherent difficulty in predicting regulatory action, fines and penalties, if any, and the various remedies and levels of judicial review available to the Company in the event of an adverse finding. As a result, the Company has not recorded any liability related to these matters. Other Litigation Matters. The Company is subject to normal and routine litigation arising from the ordinary course and conduct of business and, at times, as a result of acquisitions and dispositions. Such disputes include, for example, commercial, employment, intellectual property, environmental and securities matters. The aggregate amounts accrued related to these matters are not material to the total liabilities of the Company. The Company intends to defend itself in any such matters and does not currently believe that the outcome of any such matters will have a material adverse impact on the Company’s financial condition, results of operations or cash flows. In the first quarter of fiscal 2016, the Company recorded a charge of $1.9 million related to a litigation settlement of a contract dispute in the PSS segment.

Condensed Consolidating Financial Statements	Condensed Consolidating Financial Statements The Company has $450.0 million in outstanding Notes (see Note 8). The Notes are guaranteed by the Subsidiary Guarantors and are collateralized by the assets of all of the Company’s 100% owned subsidiaries. The Notes are fully and unconditionally guaranteed on a joint and several basis by each Subsidiary Guarantor and the Company. There are no contractual restrictions limiting cash transfers from Subsidiary Guarantors by dividends, loans or advances to the Company. The Notes are not guaranteed by the Company’s foreign subsidiaries (the “Non-Guarantor Subsidiaries”). The following tables present condensed consolidating financial statements for the parent company, the Subsidiary Guarantors and the Non-Guarantor Subsidiaries, respectively. The condensed consolidating financial information below follows the same accounting policies as described in the condensed consolidated financial statements, except for the use of the equity method of accounting to reflect ownership interests in 100% owned subsidiaries, which are eliminated upon consolidation. Also, as discussed in Note 2 - Discontinued Operations, the following condensed consolidating financial statements for the first quarter of fiscal 2015 have been recast to reflect the disposition of the Herley Entities as discontinued operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The information as of March 27, 2016 and for the three months ended March 27, 2016 and March 29, 2015 is unaudited. The condensed consolidated balance sheet as of December 27, 2015 was derived from the Company’s audited consolidated financial statements at that date. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results have been prepared in accordance with the instructions to Form 10-Q and do not necessarily include all information and footnotes necessary for presentation in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s audited annual consolidated financial statements for the fiscal year ended December 27, 2015 , included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 11, 2016 (the “Form 10-K”). Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole. As discussed in Note 2 - Discontinued Operations, the amounts related to the first quarter of fiscal 2015 in these condensed consolidated financial statements have been recast to reflect the August 21, 2015 disposition of the Company’s 100% owned subsidiary Herley Industries, Inc. (“Herley”) and certain of Herley’s subsidiaries, including Herley-CTI, Inc., EW Simulation Technology, Ltd. and Stapor Research, Inc. (collectively, the “Herley Entities”) as discontinued operations.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its 100% owned subsidiaries for which all inter-company transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year, with interim fiscal periods ending on the last Sunday of each calendar quarter. The three month periods ended March 27, 2016 and March 29, 2015 consisted of 13-week periods. There are 52 calendar weeks in the fiscal years ending on December 25, 2016 and December 27, 2015 .
Accounting Estimates	Accounting Estimates There have been no significant changes in the Company’s accounting estimates for the three months ended March 27, 2016 as compared to the accounting estimates described in the Form 10-K.
Accounting Standards Updates	Accounting Standards Updates In April 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2016-10 (“ASU 2016-10”), Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing . ASU 2016-10 provides additional guidance on identifying performance obligations and clarifies the implementation guidance on licensing. In March 2016, the FASB issued ASU 2016-08 (“ASU 2016-08”), Revenue from Contracts with Customers, Principal versus Agent Considerations. ASU 2016-08 clarifies the implementation guidance and illustrations in the new revenue standard. In August 2015, the FASB issued ASU 2015-14 (“ASU 2015-14”), Revenue from Contracts with Customers, Deferral of the Effective Date that deferred the effective date of ASU 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers. Pursuant to ASU 2015-14, public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The FASB issued ASU 2014-09 in May 2014. ASU 2014-09 affects any entity using GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards ( e.g ., insurance contracts or lease contracts). ASU 2014-09 will supersede the revenue recognition requirements in Topic 605, Revenue Recognition , and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in FASB Accounting Standards Codification (“ASC”) Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented or apply the requirements in the year of adoption, through a cumulative adjustment. The Company has not yet selected a transition method nor has it determined the impact of adoption on its condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases . ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes . The ASU eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments apply to all organizations that present a classified balance sheet. For public companies, the amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The FASB also decided to permit earlier application by all entities as of the beginning of any interim or annual reporting period. The amendment provides the reporting entity with an option to apply the amendment prospectively, or retrospectively to all prior periods presented in the financial statements. The Company adopted ASU 2015-17 prospectively for the fiscal year ended December 27, 2015. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting . ASU 2015-15 supplements the requirements of ASU 2015-03 by allowing an entity to defer and present debt issuance costs related to a line of credit arrangement as an asset and subsequently amortize the deferred costs ratably over the term of the line of credit arrangement. The Company adopted ASU 2015-15 for the fiscal year ended December 27, 2015. Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs . ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years and early adoption of the amendments is permitted for financial statements that have not been previously issued and should be applied on a retrospective basis. The Company adopted ASU 2015-03 for the fiscal year ended December 27, 2015 In January 2015, the FASB issued ASU 2015-01 (“ASU 2015-01”), Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company adopted this standard in the quarter ended March 27, 2016, which did not have a material impact on its condensed consolidated financial statements. In August 2014, the FASB issued ASU 2014-15 (“ASU 2014-15”), Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. Financial reporting under this presumption is commonly referred to as the going concern basis of accounting. The going concern basis of accounting is critical to financial reporting because it establishes the fundamental basis for measuring and classifying assets and liabilities. Currently, GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. ASU 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company does not believe that the adoption of this guidance will have a material impact on its condensed consolidated financial statements. There have been no changes in the Company’s significant accounting policies, other than the adoption of ASU 2015-01, for the three months ended March 27, 2016 as compared to the significant accounting policies described in the Form 10-K.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at March 27, 2016 and December 27, 2015 are presented in Note 8. The carrying value of all other financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued expenses, billings in excess of cost and earnings on uncompleted contracts, income taxes payable and short-term debt, approximated their estimated fair values at March 27, 2016 and December 27, 2015 due to the short-term nature of these instruments.
Net Income (Loss) Per Common Share	Net Loss Per Common Share The Company calculates net loss per share in accordance with FASB ASC Topic 260, Earnings per Share (Topic 260). Under Topic 260, basic net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the reporting period. Diluted net loss per common share reflects the effects of potentially dilutive securities.
