Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Interim Presentation	Organization and Basis of Interim Presentation Spirit AeroSystems Holdings, Inc. ("Holdings" or the "Company") was incorporated in the state of Delaware on February 7, 2005, and commenced operations on June 17, 2005 through the acquisition of Boeing's operations in Wichita, Kansas; Tulsa, Oklahoma; and McAlester, Oklahoma (the "Boeing Acquisition") by an investor group led by Onex Partners LP and Onex Corporation (together with its affiliates, "Onex"). Holdings provides manufacturing and design expertise in a wide range of fuselage, propulsion and wing products and services for aircraft original equipment manufacturers ("OEM") and operators through its subsidiary, Spirit AeroSystems, Inc. ("Spirit"). The Company has its headquarters in Wichita, Kansas, with manufacturing facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina and Subang, Malaysia. The Company has assembly facilities in Saint-Nazaire, France, and Chanute, Kansas. The Company is the majority participant in the Kansas Industrial Energy Supply Company ("KIESC"), a tenancy-in-common with other Wichita companies established to purchase natural gas. The Company participates in a joint venture, Taikoo Spirit AeroSystems Composite Co. Ltd. ("TSACCL"), of which Spirit's ownership interest is 31.5% . TSACCL was formed to develop and implement a state of the art composite and metal bond component repair station in the Asia-Pacific region. In August 2014, Onex sold its remaining investment in the Company in a secondary offering of the Company's class A common stock. In December 2014, Spirit divested its G280 and G650 programs, consisting of the design, manufacture and support of structural components for the Gulfstream G280 and G650 aircraft in Spirit’s facilities in Tulsa, Oklahoma, to Triumph Aerostructures - Tulsa, LLC, a wholly-owned subsidiary of Triumph Group Inc. ("Triumph"). The accompanying unaudited interim condensed consolidated financial statements include the Company’s financial statements and the financial statements of its majority-owned or controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the instructions to Form 10-Q and Article 10 of Regulation S-X. The Company's fiscal quarters are 13 weeks in length. Because the Company's fiscal year ends on December 31, the number of days in the Company's first and fourth quarters varies slightly from year to year. The year-end condensed balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. The Company's investment in TSACCL, in which the Company does not have a controlling interest, is accounted for under the equity method. KIESC is fully consolidated as the Company owns 77.8% of the entity’s equity. All intercompany balances and transactions have been eliminated in consolidation. The Company’s U.K. subsidiary uses local currency, the British pound, as its functional currency; the Malaysian subsidiary uses the British pound and the Singapore subsidiary uses the Singapore dollar. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency. As part of the monthly consolidation process, the Company's international entities that have functional currencies other than the U.S. dollar are translated to U.S. dollars using the end-of-month translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of operations for the interim periods. The results of operations for the six months ended July 2, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. Certain reclassifications have been made to the prior year financial statements and notes to conform to the 2015 presentation. In connection with the preparation of the condensed consolidated financial statements, the Company evaluated subsequent events through the date the financial statements were issued. The interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company's 2014 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 13, 2015 and subsequently amended on Form 10-K/A filed with the SEC on March 6, 2015 (the "2014 Form 10-K").

Changes in Estimates

Changes in Estimates [Abstract]
Change In Estimate [Text Block]	3. Changes in Estimates The Company has a Company-wide quarterly Estimate at Completion (EAC) process in which management assesses the progress and performance of the Company's contracts. This process requires management to review each program’s progress towards completion by evaluating the program schedule, changes to identified risks and opportunities, changes to estimated contract revenues and estimated contract costs over the current contract block, and any outstanding contract matters. Risks and opportunities include management's judgment about the cost associated with a program’s ability to achieve the schedule, technical requirements (e.g., a newly-developed product versus a mature product), and any other contract requirements. The majority of the Company's fixed priced contracts are life of aircraft program contracts. Due to the span of years it may take to complete a contract block and the scope and nature of the work required to be performed on those contracts, the estimation of total revenue and costs at completion is complicated and subject to many variables and, accordingly, is subject to change. When adjustments in estimated total contract block revenue or estimated total cost are required, any changes from prior estimates for delivered units are recognized in the current period as a cumulative catch-up adjustment for the inception-to-date effect of such changes. Cumulative catch-up adjustments are driven by several factors including improved production efficiencies, assumed rate of production, the rate of overhead absorption, changes to scope of work and contract modifications. When estimates of total costs to be incurred on a contract block exceed estimates of total revenue to be earned, a provision for the entire loss on the contract block is recorded in the period in which the loss is determined. Changes in estimates are summarized below: For the Three Months Ended For the Six Months Ended Changes in Estimates July 2, 2015 July 3, 2014 July 2, 2015 July 3, 2014 Favorable (Unfavorable) Cumulative Catch-up Adjustment by Segment Fuselage $ 10.8 $ 2.7 $ 10.3 $ 8.6 Propulsion 6.6 5.0 14.4 8.3 Wing (0.8 ) 11.7 (0.6 ) 13.3 Total Favorable Cumulative Catch-up Adjustment $ 16.6 $ 19.4 $ 24.1 $ 30.2 Changes in Estimates on Loss Programs and (Forward Loss) Fuselage Boeing - All other platforms $ 3.5 $ — $ 6.4 $ — Other Platforms — — — (0.9 ) Total Fuselage Change in Estimate on Loss Programs and (Forward Loss) $ 3.5 $ — $ 6.4 $ (0.9 ) Propulsion Boeing - All other platforms $ (1.3 ) $ — $ (1.3 ) $ — Total Propulsion Forward Loss $ (1.3 ) $ — $ (1.3 ) $ — Wing Other Platforms $ — $ — $ — $ (0.3 ) Total Wing Forward Loss $ — $ — $ — $ (0.3 ) Total Change in Estimate on Loss Programs and (Forward Loss), net $ 2.2 $ — $ 5.1 $ (1.2 ) Total Change in Estimate $ 18.8 $ 19.4 $ 29.2 $ 29.0 EPS Impact (diluted per share based upon statutory rates) $ 0.08 $ 0.09 $ 0.13 $ 0.13 The Company is currently working on several new and maturing programs which are in various stages of development, including the B787, A350 XWB and Rolls-Royce BR725 programs. These programs carry risks associated with design responsibility, development of production tooling, production inefficiencies during the initial phases of production, hiring and training of qualified personnel, increased capital and funding commitments, supplier performance, delivery schedules and unique customer requirements. The Company has previously recorded forward loss charges on these programs. If the risks related to these programs are not mitigated, then the Company could record additional forward loss charges.

Inventory Disclosure [Abstract]
Inventory	Inventory Inventories are summarized as follows: July 2, December 31, 2014 Raw materials $ 256.7 $ 254.5 Work-in-process 845.1 885.7 Finished goods 64.1 46.7 Product inventory 1,165.9 1,186.9 Capitalized pre-production 205.4 223.4 Deferred production 1,270.6 1,244.3 Forward loss provision (884.1 ) (901.6 ) Total inventory, net $ 1,757.8 $ 1,753.0 Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant statement of work changes considered not reimbursable by the customer can also cause pre-production costs to be incurred. These costs are typically amortized over a certain number of shipset deliveries. Deferred production includes costs for the excess of production costs over the estimated average cost per shipset, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per shipset for units delivered under the current production blocks. Recovery of excess-over-average deferred production costs is dependent on the number of shipsets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. The Company believes these amounts will be fully recovered. Sales significantly under estimates or costs significantly over estimates could result in losses on these contracts in future periods. Provisions for anticipated losses on contract blocks are recorded in the period in which they become evident (“forward losses”) and included in inventory with any remaining amount reflected in accrued contract liabilities. Non-recurring production costs include design and engineering costs and test articles. Inventories are summarized by platform and costs below: July 2, 2015 Product Inventory Inventory Non-Recurring Capitalized Pre- Production Deferred Production Forward Loss Provision Total Inventory, net July 2, 2015 B787 217.0 — 71.3 541.6 (606.0 ) 223.9 Boeing - All other platforms (1) 475.0 18.4 5.9 (19.2 ) (23.6 ) 456.5 A350 XWB 154.1 56.2 97.5 646.3 (120.1 ) 834.0 Airbus - All other platforms 86.0 — — 8.8 — 94.8 Rolls-Royce BR725 (2) 14.9 — 30.7 88.8 (134.4 ) — Aftermarket 53.7 — — — — 53.7 Other platforms 82.4 8.2 — 4.3 — 94.9 Total $ 1,083.1 $ 82.8 $ 205.4 $ 1,270.6 $ (884.1 ) $ 1,757.8 December 31, 2014 Product Inventory Inventory Non-Recurring Capitalized Pre- Production Deferred Production Forward Loss Provision Total Inventory, net December 31, 2014 B787 227.9 — 102.7 551.6 (606.0 ) 276.2 Boeing - All other platforms (1) 497.4 7.7 7.4 (8.9 ) (38.8 ) 464.8 A350 XWB 148.7 35.6 76.4 607.6 (120.1 ) 748.2 Airbus - All other platforms 82.1 — — 5.6 — 87.7 Rolls-Royce BR725 (2) 17.5 — 35.4 83.8 (136.7 ) — Aftermarket 45.2 0.2 — — — 45.4 Other platforms 113.5 11.1 1.5 4.6 — 130.7 Total $ 1,132.3 $ 54.6 $ 223.4 $ 1,244.3 $ (901.6 ) $ 1,753.0 (1) Forward loss charges recorded in prior periods on a program within Boeing - All other platforms exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability and reported in other current liabilities on the Condensed Consolidated Balance Sheet. The total contract liability was $1.8 and $2.1 as of July 2, 2015 and December 31, 2014, respectively. (2) Forward loss charges recorded in prior periods on the Rolls-Royce BR725 program exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability and reported in other current liabilities on the Condensed Consolidated Balance Sheet. The total contract liability was $14.6 and $12.2 as of July 2, 2015 and December 31, 2014, respectively. The following is a roll forward of the capitalized pre-production costs included in the inventory balance at July 2, 2015 : Balance, December 31, 2014 $ 223.4 Charges to costs and expenses (41.7 ) Capitalized costs 23.7 Balance, July 2, 2015 $ 205.4 The following is a roll forward of the deferred production costs included in the inventory balance at July 2, 2015 : Balance, December 31, 2014 $ 1,244.3 Charges to costs and expenses (428.6 ) Capitalized costs 454.4 Exchange rate 0.5 Balance, July 2, 2015 $ 1,270.6 Significant amortization of capitalized pre-production and deferred production inventory will occur over the following contract blocks: Model Contract Block Quantity Orders (1) B787 500 803 A350 XWB 400 781 Rolls-Royce BR725 350 196 (1) Orders are from the published firm-order backlogs of Airbus and Boeing. For Rolls-Royce BR725, orders represent purchase orders received from OEMs and are not reflective of OEM sales backlog. Orders reported are total block orders, including delivered units. Current block deliveries are as follows: Model Current Block Deliveries B787 348 A350 XWB 42 Rolls-Royce BR725 164 Contract block quantities are projected to fully absorb the balance of deferred production inventory. Capitalized pre-production and deferred production inventories are at risk to the extent that the Company does not achieve the orders in the forecasted blocks or if future actual costs exceed current projected estimates, as those categories of inventory are recoverable over future deliveries. In the case of capitalized pre-production this may be over multiple blocks. Should orders not materialize in future periods to fulfill the block, potential forward loss charges may be necessary to the extent the final delivered quantity does not absorb deferred inventory costs.

Advance Payments And Deferred Revenue Credits [Abstract]
Advance Payments And Deferred Revenue Credits	Advance Payments and Deferred Revenue/Credits Advance payments. Advance payments are those payments made to Spirit by customers in contemplation of the future performance of services, receipt of goods, incurrence of expenditures, or for other assets to be provided by Spirit under a contract and are repayable if such obligation is not satisfied. The amount of advance payments to be recovered against production units expected to be delivered within a year is classified as a short-term liability on the Company's consolidated balance sheet, with the balance of the unliquidated advance payments classified as a long-term liability. On April 8, 2014, the Company signed a memorandum of agreement with Boeing which suspended advance repayments related to the B787 program for a period of twelve months beginning April 1, 2014. Repayment recommenced on April 1, 2015 and any repayments which otherwise would have become due during such twelve-month period will be offset against the purchase price for shipset 1,001 and beyond. Deferred revenue/credits. Deferred revenue/credits generally consist of nonrefundable amounts received in advance of revenue being earned for specific contractual deliverables or amounts that could be required to be refunded if certain performance obligations or conditions are not met. These payments are classified as deferred revenue/credits on the Company's Condensed Consolidated Balance Sheet when received and recognized as revenue as the production units are delivered or performance obligations or conditions are met. Advance payments and deferred revenue/credits are summarized by platform as follows: July 2, December 31, 2014 B787 $ 748.5 $ 581.1 Boeing — All other platforms 15.1 16.4 A350 XWB 211.0 224.3 Airbus — All other platforms 3.6 4.1 Other 13.0 24.0 Total advance payments and deferred revenue/credits $ 991.2 $ 849.9

Government Grants [Abstract]
Government Grants	Government Grants The Company received grants in the form of government funding for a portion of the site construction and other specific capital asset costs at the Company's Kinston, North Carolina and Subang, Malaysia sites. Deferred grant income is being amortized as a reduction to production cost. This amortization is based on specific terms associated with the different grants. In North Carolina, the deferred grant income related to the capital investment criteria, which represents half of the grant, is being amortized over the lives of the assets purchased to satisfy the capital investment performance criteria. The other half of the deferred grant income is being amortized over a ten -year period, which began in 2010, in a manner consistent with the job performance criteria. Under the agreement, failure to meet job performance criteria, including creation of a targeted number of jobs, could result in Spirit making incremental rent payments to the North Carolina Global TransPark Authority over the initial term of the lease. The amount of the incremental rent payments would vary depending on Spirit’s level of attainment of these requirements not to exceed a certain dollar threshold. In Malaysia, the deferred grant income is being amortized based on the estimated lives of the eligible assets constructed with the grant funds as there are no performance criteria. The assets related to deferred grant income are consolidated within property, plant and equipment. Deferred grant income liability, net consists of the following: Balance, December 31, 2014 $ 106.3 Grant liability amortized (1.0 ) Grant income recognized (3.9 ) Total liability related to deferred grant income, July 2, 2015 $ 101.4 The asset related to the deferred grant income consists of the following: Balance, December 31, 2014 $ 113.2 Amortization (2.5 ) Exchange rate 0.1 Total asset value related to deferred grant income, July 2, 2015 $ 110.8

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB’s authoritative guidance on fair value measurements defines fair value 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 on the measurement date. It also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance discloses three levels of inputs that may be used to measure fair value: Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Observable inputs, such as current and forward interest rates and foreign exchange rates, are used in determining the fair value of the interest rate swaps and foreign currency hedge contracts. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company has historically entered into interest rate swap agreements to reduce its exposure to the variable rate portion of its long-term debt. On the inception date, the Company designates a derivative contract as either a fair value or cash flow hedge and links the contract to either a specific asset or liability on the balance sheet, or to forecasted commitments or transactions. The Company assesses, both at the hedges' inception and on a quarterly basis, whether the derivative item is effective in offsetting changes in fair value or cash flows. Any gains or losses on hedges are included in earnings when the underlying transaction that was hedged occurs. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. The Company has historically entered into derivative instruments covered by master netting arrangements whereby, in the event of a default as defined by the senior secured credit facility or termination event, the non-defaulting party has the right to offset any amounts payable against any obligation of the defaulting party under the same counterparty agreement. See Note 12, Debt for discussion of the Company's senior secured credit facilities. Interest Rate Swaps During the first quarter of 2015, as a result of Amendment No. 5 to its Credit Agreement, the Company unwound its interest rate swap agreements which had a notional amount of $250.0 . The company recognized a loss of $0.4 as a result of settling these interest rate swaps. This loss on derivatives not designated as hedging instruments is included in Other Expense on the Consolidated Statement of Operations for the six months ended July 2, 2015. In total, the Company paid $2.0 as a result of the settlement of the interest rate swap agreements. As of July 2, 2015, the Company had no outstanding interest rate swap agreements. At December 31, 2014, the fair value of interest rate swaps designated as hedging instruments was a liability of $1.1 . The impact on earnings from interest rate swaps that were no longer effective was a loss of $1.6 and $0.1 for the six months ended July 2, 2015 and July 3, 2014, respectively. The amount reclassified from accumulated other comprehensive income into income from interest rate swaps that were effective was a loss of $0.5 and zero for the six months ended July 2, 2015 and July 3, 2014, respectively. There were no gains or losses recognized in income from interest rate swaps during the second quarter of 2015 or 2014.

Share-based Compensation [Abstract]
Stock Compensation	Stock Compensation Holdings has established various stock compensation plans which include restricted share grants and stock purchase plans. Compensation values are based on the value of Holdings' common stock at the grant date. The common stock value is added to equity and charged to period expense or included in inventory and cost of sales. The Executive Incentive Plan, Short-Term Incentive Plan ("STIP"), Long-Term Incentive Plan ("LTIP") and Director Stock Plan (collectively referred to as "Prior Plans") were replaced by the Omnibus Incentive Plan (the "Omnibus Plan") in 2014. No new awards will be granted under such Prior Plans. Outstanding awards under the Prior Plans will continue to be governed by the terms of such plans until exercised, expired or otherwise terminated or canceled. The Omnibus Plan provides for a Long-Term Incentive Award ("LTIA") for the 2014 plan year and forward. The LTIAs provide both time and performance based incentives. • 75% of the LTIA is service-based restricted stock that will vest in equal installments over a three -year period. • 25% of the LTIA is performance-based restricted stock that will vest in the third year contingent upon total shareholder return ("TSR") compared to the Company’s peers. For the three months ended July 2, 2015, the Company recognized a net total of $5.0 of stock compensation expense, which is net of stock forfeitures, and includes expense for the Prior Plans and the LTIA under the Omnibus Plan. For the three months ended July 3, 2014, the Company recognized $4.3 of stock compensation expense, net of forfeitures. The entire stock compensation expense of $5.0 and $4.3 , for the three months ended July 2, 2015 and July 3, 2014, respectively, was recorded as selling, general and administrative. For the six months ended July 2, 2015, the Company recognized a net total of $11.9 of stock compensation expense, which is net of stock forfeitures, and includes expense for the Prior Plans and the LTIA under the Omnibus Plan.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The process for calculating the Company's income tax expense involves estimating actual current taxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. Deferred tax assets are periodically evaluated to determine their recoverability. The total net deferred tax liability at July 2, 2015 and December 31, 2014 were $9.5 and $5.0 , respectively. The difference is primarily due to temporary differences reducing taxable income in the United Kingdom (U.K.). The Company files income tax returns in all jurisdictions in which it operates. The Company establishes reserves to provide for additional income taxes that may be due upon audit. These reserves are established based on management’s assessment as to the potential exposure attributable to permanent tax adjustments and associated interest. All tax reserves are analyzed quarterly and adjustments made as events occur that warrant modification. In general, the Company records income tax expense each quarter based on its best estimate as to the full year’s effective tax rate. Certain items, however, are given discrete period treatment and the tax effects for such items are therefore reported in the quarter that an event arises. Events or items that give rise to discrete recognition may include finalizing amounts in income tax returns filed, finalizing audit examinations for open tax years, expiration of statutes of limitations and changes in tax law. However, the Company has determined that a calculation of an annual effective tax rate would not represent a reliable estimate for its U.S. operations due to historical differences between forecasted and actual U.S. pre-tax earnings and the effect of the Company's U.S. deferred tax valuation allowance, which create results with significant variations in the customary relationship between income tax expense and pre-tax income for the interim periods. Under the discrete method, the Company determines tax expense based upon actual results as if the interim period were an annual period. The discrete method was used for the Company's U.S. pre-tax income and an annual effective rate was used for its international pre-tax income. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, management assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses. Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding the Company's prior earnings history including the forward losses previously recognized in the U.S., management determined that it was necessary to continue to maintain a valuation allowance against nearly all of its net U.S. deferred tax assets as of July 2, 2015. At each reporting date, management considers all available positive and negative evidence, both new and historical, that could impact the future realization of deferred tax assets. Management will consider a release of the valuation allowance once there is sufficient positive evidence that it is more likely than not that the deferred tax assets will be realized, or when it is clearly demonstrated that the underlying deferred tax asset has been realized due to positive taxable income in the period the temporary difference was reversed. Any release of the valuation allowance will be recorded as a tax benefit increasing net income or other comprehensive income. The net valuation allowance was decreased by $44.1 for the six months ended July 2, 2015. The reduction reflects the realization of certain deferred tax assets within the Company’s discrete method taxable income calculation and changes in deferred tax assets associated with certain state income tax credits for the three months ended July 2, 2015. The Company's income tax expense for 2015 does not reflect any benefit of the U.S. Federal Research Tax Credit attributable to 2015 as the legislation has not been extended beyond December, 2014. Should the legislation be extended during the year, the Company may record additional tax benefits for 2015 Research Tax Credit. The 23.1% effective tax rate for the six months ended July 2, 2015 differs from the 18.0% effective tax rate for the same period of 2014 primarily due to the effect of certain non-deductible expenses within the company’s income tax provision in 2015 and the release of the Malaysia tax reserve and deferred tax liabilities in the first quarter of 2014 as a result of formal approval of the tax holiday by the Malaysian tax authorities. The Company is participating in the Internal Revenue Service’s Compliance Assurance Process (“CAP”) program for its 2014 tax year. Additionally, the Company has been selected for the Compliance Maintenance phase of the CAP program for its 2015 tax year. The CAP program’s objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. The HM Revenue & Customs completed its examination of the Company's 2009-2011 U.K. income tax returns and the statute of limitations has lapsed on the 2012 tax return. The Directorate General of Public Finance is currently examining the Company's 2011-2013 France income tax returns. While a change could result from the ongoing examinations, the Company expects no material change in its recorded unrecognized tax liability in the next 12 months.

Stockholders' Equity Note [Abstract]
Equity	Equity Earnings per Share Calculation Basic net income per share is computed using the weighted-average number of outstanding shares of common stock during the measurement period. Diluted net income per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential outstanding shares of common stock during the measurement period. Subject to preferences that may apply to shares of preferred stock outstanding at the time, holders of the Company’s outstanding common stock are entitled to any dividend declared by the Board of Directors out of funds legally available for this purpose. The Company did not pay any cash dividends in the six months ended July 2, 2015. The Company's dividend policy is dependent on the requirements of financing agreements to which the Company is party to. Any future determination to pay dividends will be at the discretion of the Company's Board of Directors and will depend upon, among other factors, the Company's results of operations, financial condition, capital requirements and contractual restrictions. The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ equity. As of July 2, 2015 , no treasury shares have been reissued or retired.

Commitments Contingencies And Guarantees [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Litigation From time to time the Company is subject to, and is presently involved in, litigation or other legal proceedings arising in the ordinary course of business. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available, it is the opinion of the Company that none of these items, when finally resolved, will have a material adverse effect on the Company’s long-term financial position or liquidity. The Company had outstanding obligations in respect of litigation or other legal proceedings of $55.5 and $96.3 as of July 2, 2015 and December 31, 2014, respectively. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations and cash flows in a particular quarter or fiscal year. From time to time, in the ordinary course of business and similar to others in the industry, the Company receives requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. The Company reviews such requests and notices and take appropriate action. The Company has been subject to certain requests for information and investigations in the past and could be subject to such requests for information and investigations in the future. Additionally, the Company is subject to federal and state requirements for protection of the environment, including those for disposal of hazardous waste and remediation of contaminated sites. As a result, the Company is required to participate in certain government investigations regarding environmental remediation actions. On December 5, 2014, The Boeing Company (“Boeing”) filed a complaint in Delaware Superior Court, Complex Commercial Litigation Division, entitled The Boeing Co. v. Spirit AeroSystems, Inc., No. N14C-12-055 (EMD). Boeing seeks indemnification from Spirit for (a) damages assessed against Boeing in International Union, United Automobile, Aerospace and Agricultural Workers of America v. Boeing Co., AAA Case No. 54 300 00795 07 (the “UAW Arbitration”), which was brought on behalf of certain former Boeing employees in Tulsa and McAlester, Oklahoma, and (b) claims that Boeing allegedly settled in Society of Professional Engineering Employees in Aerospace v. Boeing Co., Nos. 05-1251-MLB, 07-1043-MLB (D. Kan.) (the “Harkness Class Action”). Spirit Holdings, Spirit and certain Spirit retirement plan entities were parties to the Harkness Class Action, but all claims against the Spirit entities were subsequently dismissed. Boeing’s Complaint asserts that the damages assessed against Boeing in the UAW Arbitration and the claims settled by Boeing in the Harkness Class Action are liabilities that Spirit assumed under an Asset Purchase Agreement between Boeing and Spirit, dated February 22, 2005 (the “APA”). Boeing asserts claims for breach of contract and declaratory judgment regarding its indemnification rights under the APA. Boeing alleges that, under the UAW Arbitration decision, Boeing has paid more than $13.0 of a liability Boeing estimates to have a net present value of $39.0 . The amount of Boeing’s settlement of the Harkness Class Action has not yet been publicly disclosed and will require court approval. In addition, Boeing seeks indemnification for more than $10.0 in attorneys’ fees it alleges it expended to defend the UAW Arbitration and Harkness Class Action. On December 24, 2014, the parties filed a joint stipulation extending Spirit’s deadline to move, answer or otherwise respond to Boeing’s complaint until February 12, 2015. Spirit timely moved to dismiss the complaint. Spirit intends to defend vigorously against the allegations in this lawsuit. Management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations or liquidity. On June 3, 2013, a putative class action lawsuit was commenced against the Company, Jeffrey L. Turner, and Philip D. Anderson in the U.S. District Court for the District of Kansas. The court-appointed lead plaintiffs - two pension funds that claim to represent a class of investors in the Company's stock - filed an amended complaint on April 7, 2014, naming as additional defendants Spirit's Vice President of the B787 Program Terry J. George and former Senior Vice President of Oklahoma Operations Alexander K. Kummant. The amended complaint alleges that defendants engaged in a scheme to artificially inflate the market price of the Company's stock by making false statements and omissions about certain programs' performance and costs. It contends that the alleged scheme was revealed by the Company’s accrual of $590.0 in forward loss charges on October 25, 2012. The lead plaintiffs seek certification of a class of all persons other than defendants who purchased Holdings securities between May 5, 2011 and October 24, 2012, and seek an unspecified amount of damages on behalf of the putative class. In June 2014, the defendants filed a motion to dismiss the claims set forth in the amended complaint. On May 14, 2015, the District Court granted Spirit's motion to dismiss and dismissed the matter with prejudice. The plaintiffs filed a notice of appeal on June 11, 2015, which is pending. The Company intends to vigorously defend against these allegations, and management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations or liquidity. Guarantees Outstanding guarantees were $20.6 and $21.6 at July 2, 2015 and December 31, 2014, respectively. Restricted Cash The Company was required to maintain $19.9 of restricted cash as of both July 2, 2015 and December 31, 2014 related to certain collateral requirements for obligations under its workers’ compensation programs. These collateral requirements were previously supported by letters of credit that were replaced in October 2014. Restricted cash is included in “Other assets” in the Company's Condensed Consolidated Balance Sheets. Indemnification The Company has entered into customary indemnification agreements with each of its Directors, and some of its executive employment agreements include indemnification provisions. Under those agreements, the Company agrees to indemnify each of these individuals against claims arising out of events or occurrences related to that individual’s service as the Company’s agent or the agent of any of its subsidiaries to the fullest extent legally permitted. Service and Product Warranties and Extraordinary Rework Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These costs are accrued at the time of the sale and are recorded to unallocated cost of goods sold. These estimates are established using historical information on the nature, frequency and average cost of warranty claims, including the experience of industry peers. In the case of new development products or new customers, Spirit considers other factors including the experience of other entities in the same business and management judgment, among others. Service warranty and extraordinary work is reported in other liabilities on the Condensed Consolidated Balance Sheet. The following is a roll forward of the service warranty and extraordinary rework balance at July 2, 2015 : Balance, December 31, 2014 $ 119.9 Charges to costs and expenses 22.9 Payouts (0.5 ) Exchange rate — Balance, July 2, 2015 $ 142.3

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information The Company operates in three principal segments: Fuselage Systems, Propulsion Systems and Wing Systems. Substantially all revenues in the three principal segments are from Boeing, with the exception of Wing Systems, which includes revenues from Airbus and other customers. Approximately 95% of the Company’s net revenues for the six months ended July 2, 2015 came from the Company's two largest customers, Boeing and Airbus. All other activities fall within the All Other segment, principally made up of sundry sales of miscellaneous services, tooling contracts and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita, Kansas. The Company's primary profitability measure to review a segment’s operating performance is segment operating income before corporate selling, general and administrative expenses, research and development and unallocated cost of sales. Corporate selling, general and administrative expenses include centralized functions such as accounting, treasury and human resources that are not specifically related to the Company's operating segments and are not allocated in measuring the operating segments’ profitability and performance and net profit margins. Research and development includes research and development efforts that benefit the Company as a whole and are not unique to a specific segment. Unallocated cost of sales includes general costs not directly attributable to segment operations, such as warranty, early retirement and other incentives. All of these items are not specifically related to the Company's operating segments and are not utilized in measuring the operating segments’ profitability and performance. The Company’s Fuselage Systems segment includes development, production and marketing of forward, mid and rear fuselage sections and systems, primarily to aircraft OEMs (OEM refers to aircraft original equipment manufacturer), as well as related spares and maintenance, repairs and overhaul (MRO) services. The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas and Kinston, North Carolina. The Fuselage Systems segment also includes an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France. The Company’s Propulsion Systems segment includes development, production and marketing of struts/pylons, nacelles (including thrust reversers) and related engine structural components primarily to aircraft or engine OEMs, as well as related spares and MRO services. The Propulsion Systems segment manufactures products at our facilities in Wichita and Chanute, Kansas. The Company’s Wing Systems segment includes development, production and marketing of wings and wing components (including flight control surfaces) as well as other miscellaneous structural parts primarily to aircraft OEMs, as well as related spares and MRO services. These activities take place at the Company’s facilities in Tulsa and McAlester, Oklahoma; Kinston, North Carolina; Prestwick, Scotland; and Subang, Malaysia. The Company’s segments are consistent with the organization and responsibilities of management reporting to the chief operating decision-maker for the purpose of assessing performance. The Company’s definition of segment operating income differs from net profit margin as presented in its primary financial statements and a reconciliation of the segment and consolidated results is provided in the table set forth below. While some working capital accounts are maintained on a segment basis, much of the Company’s assets are not managed or maintained on a segment basis. Property, plant and equipment, including tooling, is used in the design and production of products for each of the segments and, therefore, is not allocated to any individual segment. In addition, cash, prepaid expenses, other assets and deferred taxes are managed and maintained on a consolidated basis and generally do not pertain to any particular segment. Raw materials and certain component parts are used in the production of aerostructures across all segments. Work-in-process inventory is identifiable by segment, but is managed and evaluated at the program level. As there is no segmentation of the Company’s productive assets, depreciation expense (included in fixed manufacturing costs and selling, general and administrative expenses) and capital expenditures, no allocation of these amounts has been made solely for purposes of segment disclosure requirements. The following table shows segment revenues and operating income for the three and six months ended July 2, 2015 and July 3, 2014 : Three Months Ended Six Months Ended July 2, July 3, July 2, July 3, Segment Revenues Fuselage Systems $ 887.6 $ 905.0 $ 1,804.4 $ 1,763.3 Propulsion Systems 440.5 460.5 886.5 910.7 Wing Systems (1) 367.5 438.3 744.2 852.5 All Other 3.1 (0.5 ) 5.8 5.3 $ 1,698.7 $ 1,803.3 $ 3,440.9 $ 3,531.8 Segment Operating Income (Loss) Fuselage Systems $ 168.0 $ 132.2 $ 332.5 $ 274.2 Propulsion Systems 88.2 86.2 183.9 166.4 Wing Systems 50.1 71.0 95.3 121.0 All Other 1.4 0.2 1.1 0.3 307.7 289.6 612.8 561.9 Corporate SG&A (53.8 ) (54.4 ) (105.4 ) (114.9 ) Research and development (6.7 ) (6.8 ) (13.7 ) (13.1 ) Unallocated cost of sales (2) (16.9 ) (12.2 ) (28.1 ) (23.3 ) Total operating income $ 230.3 $ 216.2 $ 465.6 $ 410.6 (1) In December 2014, Spirit divested the Gulfstream G280 and G650 wing work packages to Triumph.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	2. New Accounting Pronouncements In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU ") No. 2015-03, Interest - Imputation of Interest, (FASB ASU 2015-03) which 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 of debt issuance costs are not affected by the amendments in this update. FASB ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015 and requires the Company to apply the new guidance on a retrospective basis upon adoption. The adoption of FASB ASU 2015-03 is not expected to have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, Consolidation: Amendments to the Consolidation Analysis (FASB ASU 2015-02). FASB ASU 2015-02 amended the process that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. FASB ASU 2015-02 is effective for the annual period ending after December 15, 2015, and for annual periods and interim periods thereafter. The Company has elected, as permitted by the standard, to adopt FASB ASU 2015-02 early, to be effective for the second quarter ended July 2, 2015. The adoption of FASB ASU 2015-02 did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition (FASB ASU 2014-09). This update is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. FASB ASU 2014-09 is effective in annual periods beginning after December 15, 2016 and for interim and annual reporting periods thereafter. Early application is not permitted for public entities. In July 2015, the FASB affirmed its proposal to defer the effective date of the ASU 2014-09 for all entities by one year. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, with an option that would permit companies to adopt the standard as early as the original effective date. Early adoption prior to the original effective date is not permitted. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements.

These programs carry risks associated with design responsibility, development of production tooling, production inefficiencies during the initial phases of production, hiring and training of qualified personnel, increased capital and funding commitments, supplier performance, delivery schedules and unique customer requirements. The Company has previously recorded forward loss charges on these programs. If the risks related to these programs are not mitigated, then the Company could record additional forward loss charges.
