Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Consolidation and Classification. The unaudited Consolidated Financial Statements include the accounts of General Dynamics Corporation and our wholly owned and majority-owned subsidiaries. We eliminate all inter-company balances and transactions in the unaudited Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term production contracts as current, even though some of these amounts may not be realized within one year.
	Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. These rules and regulations permit some of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) to be condensed or omitted.
	Our fiscal quarters are 13 weeks in length. Because our fiscal year ends on December 31, the number of days in our first and fourth quarters varies slightly from year to year. Operating results for the three- and nine-month periods ended September 29, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	The unaudited Consolidated Financial Statements contain all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations and financial condition for the three- and nine-month periods ended September 30, 2012, and September 29, 2013.
	These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012.
	Revenue Recognition. We account for revenues and earnings using the percentage-of-completion method. Under this method, contract costs and revenues are recognized as the work progresses, either as the products are produced or as services are rendered. We estimate the profit on a contract as the difference between the total estimated revenue and costs to complete a contract and recognize that profit over the life of the contract. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the loss in the quarter it is identified.
	We review and update our contract estimates regularly. We recognize changes in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of a revision in estimate is recognized prospectively over the remaining contract term. The net increase in our operating earnings (and on a diluted per-share basis) from the favorable impact of revisions in contract estimates totaled $45 ($0.09) and $203 ($0.39) for the three- and nine-month periods ended September 30, 2012, and $105 ($0.19) and $296 ($0.54) for the three- and nine-month periods ended September 29, 2013, respectively. While no revisions on any one contract were material to our unaudited Consolidated Financial Statements in the third quarter and first nine months of 2013, the amounts increased from 2012 largely due to improved performance in the Combat Systems group.
	Subsequent Events. We have evaluated material events and transactions that have occurred after the balance sheet date and concluded that no subsequent events have occurred that require adjustment to or disclosure in this Form 10-Q.

Earnings Per Share [Abstract]
Earnings And Dividends Per Share	EARNINGS PER SHARE
	Earnings per Share. We compute basic earnings per share (EPS) using net earnings for the period and the weighted average number of common shares outstanding during the period. Diluted EPS generally incorporates the additional shares issuable upon the assumed exercise of stock options and the release of restricted shares and restricted stock units (RSUs). Basic and diluted weighted average shares outstanding were as follows (in thousands):
		Three Months Ended		Nine Months Ended
		September 30, 2012	September 29, 2013	September 30, 2012	September 29, 2013
	Basic weighted average shares outstanding	350,470	349,337	354,168	350,774
	Dilutive effect of stock options and restricted stock/RSUs*	2,356	3,581	2,351	2,348
	Diluted weighted average shares outstanding	352,826	352,918	356,519	353,122
	* Excludes the following outstanding options to purchase shares of common stock because the effect of including these options would be antidilutive: 2012 - 23,777 and 2013 - 10,992.

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between marketplace participants. Various valuation approaches can be used to determine fair value, each requiring different valuation inputs. The following hierarchy classifies the inputs used to determine fair value into three levels:
	•	Level 1 – quoted prices in active markets for identical assets or liabilities;
	•	Level 2 – inputs, other than quoted prices, observable by a marketplace participant either directly or indirectly; and
	•	Level 3 – unobservable inputs significant to the fair value measurement.
	We did not have any significant non-financial assets or liabilities measured at fair value on December 31, 2012, or September 29, 2013, except for long-lived assets that were impaired in December 2012, including goodwill in our Information Systems and Technology business group.
	Our financial instruments include cash and equivalents, marketable securities and other investments; accounts receivable and accounts payable; short- and long-term debt; and derivative financial instruments. The carrying values of cash and equivalents, accounts receivable and payable, and short-term debt on the Consolidated Balance Sheets approximate their fair value. The following tables present the fair values of our other financial assets and liabilities on December 31, 2012, and September 29, 2013, and the basis for determining their fair values:
		Carrying			Fair			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs
		Value			Value			(Level 1)		(Level 2) (a)
	Financial assets (liabilities) (b)	December 31, 2012

	(a)Determined under a market approach using valuation models that incorporate observable inputs such as interest rates, bond yields and quoted prices for similar assets and liabilities.
	(b)We had no Level 3 financial instruments on December 31, 2012, or September 29, 2013.

Contracts_In_Process

Contracts In Process	9 Months Ended
	Sep. 29, 2013
Contractors [Abstract]
Contracts In Process	CONTRACTS IN PROCESS
	Contracts in process represent recoverable costs and, where applicable, accrued profit related to long-term contracts that have been inventoried until the customer is billed, and consisted of the following:
		December 31, 2012			September 29, 2013
	Contract costs and estimated profits	$	8,162		$	8,479
	Other contract costs	1,089			1,174
		9,251			9,653
	Advances and progress payments	(4,287		)	(4,540		)
	Total contracts in process	$	4,964		$	5,113
	Contract costs consist primarily of labor, material, overhead and G&A expenses. Other contract costs represent amounts that are not currently allocable to government contracts, such as a portion of our estimated workers’ compensation obligations, other insurance-related assessments, pension and other post-retirement benefits and environmental expenses. These costs will become allocable to contracts generally after they are paid. We expect to recover these costs through ongoing business, including existing backlog and probable follow-on contracts. If the backlog in the future does not support the continued deferral of these costs, the profitability of our remaining contracts could be adversely affected.

Inventories

Inventory Disclosure [Abstract]
Inventories	INVENTORIES
	Our inventories represent primarily business-jet components and are stated at the lower of cost or net realizable value. Work-in-process represents largely labor, material and overhead costs associated with aircraft in the manufacturing process and is based primarily on the estimated average unit cost of the units in a production lot. Raw materials are valued primarily on the first-in, first-out method. We record pre-owned aircraft acquired in connection with the sale of new aircraft at the lower of the trade-in value or the estimated net realizable value. Inventories consisted of the following:
		December 31, 2012		September 29, 2013
	Work in process	$	1,518	$	1,674

	Our fixed-rate notes are fully and unconditionally guaranteed by several of our 100-percent-owned subsidiaries (see Note O for condensed consolidating financial statements). We have the option to redeem the notes prior to their maturity in whole or part for the principal plus any accrued but unpaid interest and applicable make-whole amounts.
	While we had no commercial paper outstanding on September 29, 2013, we issued approximately $500 of commercial paper subsequent to the end of the quarter to bolster liquidity in the current business environment. We have $2 billion in committed bank credit facilities that provide backup liquidity to our commercial paper program. These credit facilities include a $1 billion multi-year facility expiring in July 2016 and a $1 billion multi-year facility expiring in July 2018 that replaces a facility that expired in July 2013. These facilities are required by the rating agencies to support our commercial paper issuances. We may renew or replace, in whole or part, these credit facilities at or prior to their expiration dates. Our commercial paper issuances and the bank credit facilities are guaranteed by several of our 100-percent-owned subsidiaries. In addition, we have approximately $280 in committed bank credit facilities to provide backup liquidity to our European businesses.
	Our financing arrangements contain a number of customary covenants and restrictions. We were in compliance with all material covenants on September 29, 2013.

	Workers' compensation	578		520
	Retirement benefits	318		326

	Deferred income taxes	144		131
	Other (b)	727		790
	Total other liabilities	$	7,391	$	6,893
	(a)Consists primarily of dividends payable, taxes payable, environmental remediation reserves, warranty reserves, liabilities of discontinued operations and insurance-related costs.
	(b)Consists primarily of liabilities for warranty reserves and workers' compensation.
	The increase in the September 29, 2013, other current liabilities amount is primarily due to $198 of dividends payable. We did not have any dividends payable on December 31, 2012, because we paid our first quarter 2013 dividend in December 2012. The decrease in the September 29, 2013, noncurrent retirement benefits amount is primarily due to over $500 of contributions to our pension plans in 2013.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	Deferred Tax Assets. Our net deferred tax asset was included on the Consolidated Balance Sheets in other assets and liabilities as follows:
		December 31, 2012			September 29, 2013
	Current deferred tax asset	$	44		$	36
	Current deferred tax liability	(173		)	(343		)
	Noncurrent deferred tax asset	1,251			1,240
	Noncurrent deferred tax liability	(144		)	(131		)
	Net deferred tax asset	$	978		$	802
	Tax Uncertainties. For all periods open to examination by tax authorities, we periodically assess our liabilities and contingencies based on the latest available information. Where we believe there is more than a 50 percent chance that our tax position will not be sustained, we record our best estimate of the resulting tax liability, including interest, in the Consolidated Financial Statements. We include any interest or penalties incurred in connection with income taxes as part of income tax expense.
	We participate in the Internal Revenue Service (IRS) Compliance Assurance Process, a real-time audit of our consolidated corporate federal income tax return. The IRS has examined our consolidated federal income tax returns through 2011. We do not expect the resolution of tax matters for open years to have a material impact on our results of operations, financial condition, cash flows or effective tax rate.
	Based on all known facts and circumstances and current tax law, we believe the total amount of unrecognized tax benefits on September 29, 2013, is not material to our results of operations, financial condition or cash flows, and if recognized, would not have a material impact on our effective tax rate. We further believe that there are no tax positions for which it is reasonably possible that the unrecognized tax benefits will significantly vary over the next 12 months, producing, individually or in the aggregate, a material effect on our results of operations, financial condition or cash flows.

Derivative Instruments And Hedging Activities	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments And Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
	We are exposed to market risk, primarily from foreign currency exchange rates, interest rates, commodity prices and investments. We may use derivative financial instruments to hedge some of these risks as described below. We do not use derivatives for trading or speculative purposes.
	Foreign Currency Risk. Our foreign currency exchange rate risk relates to receipts from customers, payments to suppliers and inter-company transactions denominated in foreign currencies. To the extent possible, we include terms in our contracts that are designed to protect us from this risk. Otherwise, we enter into derivative financial instruments, principally foreign currency forward purchase and sale contracts, designed to offset and minimize our risk. The one year average maturity of these instruments matches the duration of the activities that are at risk.
	Interest Rate Risk. Our financial instruments subject to interest rate risk include fixed-rate long-term debt obligations and variable-rate commercial paper. However, the risk associated with these instruments is not material.
	Commodity Price Risk. We are subject to risk of rising labor and commodity prices, primarily on long-term fixed-price contracts. To the extent possible, we include terms in our contracts that are designed to protect us from this risk. Some of the protective terms included in our contracts are considered derivatives but are not accounted for separately because they are clearly and closely related to the host contract. We have not entered into any material commodity hedging contracts but may do so as circumstances warrant. We do not believe that changes in labor or commodity prices will have a material impact on our results of operations or cash flows.
	Investment Risk. Our investment policy allows for purchases of fixed-income securities with an investment-grade rating and a maximum maturity of up to five years. On September 29, 2013, we held $4.1 billion in cash and equivalents, but held no marketable securities.
	Hedging Activities. We had $2.5 billion in notional forward exchange contracts outstanding on December 31, 2012, and $2 billion on September 29, 2013. We recognize derivative financial instruments on the Consolidated Balance Sheets at fair value (see Note D).
	We record changes in the fair value of derivative financial instruments in operating costs and expenses in the Consolidated Statements of Earnings or in OCI within the Consolidated Statements of Comprehensive Income depending on whether the derivative is designated and qualifies for hedge accounting. Gains and losses related to derivatives that qualify as cash flow hedges are deferred in OCI until the underlying transaction is reflected in earnings. We adjust derivative financial instruments not designated as cash flow hedges to market value each period and record the gain or loss in the Consolidated Statements of Earnings. The gains and losses on these instruments generally offset losses and gains on the assets, liabilities and other transactions being hedged. Gains and losses resulting from hedge ineffectiveness are recognized in the Consolidated Statements of Earnings for all derivative financial instruments, regardless of designation.
	Net gains and losses recognized in earnings and OCI, including gains and losses related to hedge ineffectiveness, were not material to our results of operations for the three- and nine-month periods ended September 30, 2012, and September 29, 2013. We do not expect the amount of gains and losses in OCI that will be reclassified to earnings during the next 12 months to be material.
	We had no material derivative financial instruments designated as fair value or net investment hedges on December 31, 2012, or September 29, 2013.
	Foreign Currency Financial Statement Translation. We translate foreign-currency balance sheets from our international businesses' functional currency (generally the respective local currency) to U.S. dollars at the end-of-period exchange rates, and statements of earnings at the average exchange rates for each period. The resulting foreign currency translation adjustments are a component of OCI.
	We do not hedge the fluctuation in reported revenues and earnings resulting from the translation of these international operations' results into U.S. dollars. The impact of translating our international operations’ revenues and earnings into U.S. dollars was not material to our results of operations for the three- and nine-month periods ended September 30, 2012, or September 29, 2013. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material in the first three months or nine months of either 2012 or 2013.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES
	Litigation
	Termination of A-12 Program. The A-12 aircraft contract was a fixed-price incentive contract for the full-scale development and initial production of the carrier-based Advanced Tactical Aircraft with the U.S. Navy and a team composed of contractors General Dynamics and McDonnell Douglas (now a subsidiary of The Boeing Company). In January 1991, the U.S. Navy terminated the contract for default and demanded the contractors repay $1.4 billion in unliquidated progress payments. Following the termination, the Navy agreed to defer the collection of that amount pending a negotiated settlement or other resolution. Both contractors had full responsibility to the Navy for performance under the contract, and both are jointly and severally liable for potential liabilities arising from the termination.
	Over 20 years of litigation, the trial court (the U.S. Court of Federal Claims), appeals court (the Court of Appeals for the Federal Circuit) and the U.S. Supreme Court have issued various rulings, some in favor of the government and others in favor of the contractors.
	In May 2007, the trial court issued a decision upholding the government’s determination of default. This decision was affirmed by a three-judge panel of the appeals court in June 2009, and in November 2009 the court of appeals denied the contractors’ petitions for rehearing. In September 2010, the U.S. Supreme Court granted the contractors’ petitions for review as to whether the government could maintain its default claim against the contractors while invoking the state-secrets privilege to deny the contractors a defense to that claim.
	In May 2011, the U.S. Supreme Court vacated the judgment of the court of appeals, stating that the contractors had a plausible superior knowledge defense that had been stripped from them as a consequence of the government’s assertion of the state-secrets privilege. In particular, the U.S. Supreme Court held that, in that circumstance, neither party can obtain judicial relief.
	In addition, the U.S. Supreme Court remanded the case to the court of appeals for further proceedings on whether the government has an obligation to share its superior knowledge with respect to highly classified information, whether the government has such an obligation when the agreement specifies information that must be shared (as was the case with respect to the A-12 contract), and whether these questions can safely be litigated by the courts without endangering state secrets. In July 2011, the appeals court remanded these issues to the trial court for further proceedings consistent with the U.S. Supreme Court’s opinion. These issues remain to be resolved on remand.
	The government and the contractors are now pursuing efforts that could, if successful, finally and fully settle this longstanding dispute. A written settlement agreement between the contractors and the Navy has been signed that provides for in-kind consideration to be provided by the contractors in exchange for dismissal of the case. Under the settlement agreement we would provide a credit to the Navy in the amount of $198 toward the design, construction and delivery of portions of a ship in the DDG-1000 program. The settlement agreement is contingent largely upon approval by Congress of legislation that would authorize the Navy to receive and retain payment in-kind for the settlement. If the legislation is ultimately not adopted by Congress, the settlement agreement will become null and void. We do not know the timing of any potential Congressional action to adopt the legislation, and the case is stayed pending Congressional action.
	If settlement efforts are not successful and the case proceeds, we believe that the lower courts will ultimately rule in the contractors’ favor on the remaining issues in the case. We expect this would leave all parties where they stood prior to the contracting officer’s declaration of default, meaning that no money would be due from one party to another. Additionally, even if the lower courts were to sustain the government’s default claim, we continue to believe that there are significant legal obstacles to the government’s ability to collect any amount from the contractors given that no court has ever awarded a money judgment to the government. For these reasons, we have not recorded an accrual for this matter.
	If, contrary to our expectations, a settlement is not reached and the government prevails on its default claim and its recovery theories, the contractors could collectively be required to repay the government, on a joint and several basis, as much as $1.4 billion for progress payments received for the A-12 contract plus interest. Interest was approximately $1.6 billion on September 29, 2013. This would result in a liability to us of half of the total (based upon The Boeing Company satisfying McDonnell Douglas’ obligations under the contract), or approximately $1.5 billion pretax. Our after-tax charge would be approximately $840, or $2.38 per share, which would be recorded in discontinued operations. Our after-tax cash cost would be approximately $745. We believe we have sufficient resources to satisfy our obligation if required.
	Other. Various claims and other legal proceedings incidental to the normal course of business are pending or threatened against us. These matters relate to such issues as government investigations and claims, the protection of the environment, asbestos-related claims and employee-related matters. The nature of litigation is such that we cannot predict the outcome of these matters. However, based on information currently available, we believe any potential liabilities in these proceedings, individually or in the aggregate, will not have a material impact on our results of operations, financial condition or cash flows.
	Environmental
	We are subject to and affected by a variety of federal, state, local and foreign environmental laws and regulations. We are directly or indirectly involved in environmental investigations or remediation at some of our current and former facilities and third-party sites that we do not own but where we have been designated a Potentially Responsible Party (PRP) by the U.S. Environmental Protection Agency or a state environmental agency. Based on historical experience, we expect that a significant percentage of the total remediation and compliance costs associated with these facilities will continue to be allowable contract costs and, therefore, recoverable under U.S. government contracts.
	As required, we provide financial assurance for certain sites undergoing or subject to investigation or remediation. We accrue environmental costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. Where applicable, we seek insurance recovery for costs related to environmental liabilities. We do not record insurance recoveries before collection is considered probable. Based on all known facts and analyses, we do not believe that our liability at any individual site, or in the aggregate, arising from such environmental conditions, will be material to our results of operations, financial condition or cash flows. We also do not believe that the range of reasonably possible additional loss beyond what has been recorded would be material to our results of operations, financial condition or cash flows.
	Other
	Portugal Program. In 2012, the Portuguese Ministry of National Defense notified our Combat Systems group's European Land Systems business that it was terminating the contract to provide 260 Pandur vehicles based on an alleged breach of contract. Subsequently, the customer drew $75 from bank guarantees for the contract. We have asserted that we are not in breach of the contract and that the termination of the contract was invalid, and we are currently in arbitration with the customer. Given the uncertainty of receiving further payments, we reserved the receivables and contracts in process balances and accrued an estimate of the remaining costs related to the close-out of the contract, totaling $258 in 2012. As of September 29, 2013, approximately $195 of bank guarantees relating to the program and its related offset requirements remained outstanding. The bank guarantees could be drawn upon by the customer through 2014 and, therefore, have a possible impact on our future operating results and cash flows.
	Letters of Credit and Guarantees. In the ordinary course of business, we have entered into letters of credit, bank guarantees, surety bonds and other similar arrangements with financial institutions and insurance carriers totaling approximately $1.8 billion on September 29, 2013. In addition, from time to time in the ordinary course of business, we contractually guarantee the payment or performance obligations of our subsidiaries arising under certain contracts.
	Government Contracts. As a government contractor, we are subject to U.S. government audits and investigations relating to our operations, including claims for fines, penalties, and compensatory and treble damages. We believe the outcome of such ongoing government disputes and investigations will not have a material impact on our results of operations, financial condition or cash flows.
	In the performance of our contracts, we routinely request contract modifications that require additional funding from the customer. Most often, these requests are due to customer-directed changes in scope of work. While we are entitled to recovery of these costs under our contracts, the administrative process with our customer may be protracted. Based upon the circumstances, we periodically file claims or requests for equitable adjustment (REAs). In some cases, these requests are disputed by our customer. We believe our outstanding modifications and other claims will be resolved without material impact to our results of operations, financial condition or cash flows.
	Aircraft Trade-ins. In connection with orders for new aircraft in funded contract backlog, our Aerospace group has outstanding options with some customers to trade in aircraft as partial consideration in their new-aircraft transaction. These trade-in commitments are structured to establish the fair market value of the trade-in aircraft at a date generally 120 or fewer days preceding delivery of the new aircraft to the customer. At that time, the customer is required to either exercise the option or allow its expiration. Any excess of the pre-established trade-in price above the fair market value at the time the new aircraft is delivered is treated as a reduction of revenue in the new-aircraft sales transaction.
	Product Warranties. We provide warranties to our customers associated with certain product sales. We record estimated warranty costs in the period in which the related products are delivered. The warranty liability recorded at each balance sheet date is generally based on the number of months of warranty coverage remaining for products delivered and the average historical monthly warranty payments. Warranty obligations incurred in connection with long-term production contracts are accounted for within the contract estimates at completion. Our other warranty obligations, primarily for business-jet aircraft, are included in other current and noncurrent liabilities on the Consolidated Balance Sheets.
	The changes in the carrying amount of warranty liabilities for the nine-month periods ended September 30, 2012, and September 29, 2013, were as follows:
	Nine Months Ended	September 30, 2012			September 29, 2013

	Net periodic cost	$	330		$	440		$	43		$	54
	Our contractual arrangements with the U.S. government provide for the recovery of contributions to our pension and other post-retirement benefit plans covering employees working in our defense business groups. For non-funded plans, our government contracts allow us to recover claims paid. Following payment, these recoverable amounts are allocated to contracts and billed to the customer in accordance with the Cost Accounting Standards (CAS) and specific contractual terms. For some of these plans, the cumulative pension and post-retirement benefit cost exceeds the amount currently allocable to contracts. To the extent recovery of the cost is considered probable based on our backlog and probable follow-on contracts, we defer the excess in contracts in process on the Consolidated Balance Sheets until the cost is allocable to contracts. See Note E for discussion of our deferred contract costs. For other plans, the amount allocated to contracts and included in revenues has exceeded the plans’ cumulative benefit cost. We have deferred recognition of these excess earnings to provide a better matching of revenues and expenses. These deferrals have been classified against the plan assets on the Consolidated Balance Sheets.
	In late 2011, changes were made to the CAS to harmonize the regulations with the Pension Protection Act of 2006. As a result, pension costs allocable to our contracts are expected to increase beginning in 2014 when the impact of the CAS regulations begins to take effect. For certain contracts awarded prior to February 27, 2012, we are entitled to recovery of these additional pension costs. We submitted REAs of approximately $165 for these contracts in 2012. These REAs remain outstanding on September 29, 2013, and are subject to negotiation with our customer, the U.S. Department of Defense.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 29, 2013
Accounting Policies [Abstract]
Basis of Consolidation and Classification	Basis of Consolidation and Classification. The unaudited Consolidated Financial Statements include the accounts of General Dynamics Corporation and our wholly owned and majority-owned subsidiaries. We eliminate all inter-company balances and transactions in the unaudited Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term production contracts as current, even though some of these amounts may not be realized within one year.
Interim Financial Statements	Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. These rules and regulations permit some of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) to be condensed or omitted.
	Our fiscal quarters are 13 weeks in length. Because our fiscal year ends on December 31, the number of days in our first and fourth quarters varies slightly from year to year. Operating results for the three- and nine-month periods ended September 29, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	The unaudited Consolidated Financial Statements contain all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations and financial condition for the three- and nine-month periods ended September 30, 2012, and September 29, 2013.
	These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012.
Revenue Recognition	Revenue Recognition. We account for revenues and earnings using the percentage-of-completion method. Under this method, contract costs and revenues are recognized as the work progresses, either as the products are produced or as services are rendered. We estimate the profit on a contract as the difference between the total estimated revenue and costs to complete a contract and recognize that profit over the life of the contract. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the loss in the quarter it is identified.
	We review and update our contract estimates regularly. We recognize changes in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of a revision in estimate is recognized prospectively over the remaining contract term.
Subsequent Events	Subsequent Events. We have evaluated material events and transactions that have occurred after the balance sheet date and concluded that no subsequent events have occurred that require adjustment to or disclosure in this Form 10-Q.
