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. Some prior-year amounts have been reclassified among financial statement accounts to conform to the current-year presentation. Consistent with defense industry practice, we classify assets and liabilities related to long-term 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 October 2, 2016 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 . 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 October 2, 2016 , and October 4, 2015 . 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, 2015 . Revenue Recognition. We account for revenue and earnings using the percentage-of-completion method. Under this method, we recognize contract costs and revenue 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 expected 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-related estimates regularly. We recognize adjustments in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of an adjustment in estimate is recognized prospectively over the remaining contract term. The net impact of adjustments in contract estimates on our operating earnings (and on a diluted per-share basis) totaled favorable adjustments of $44 ( $0.09 ) and $231 ( $0.48 ) for the three- and nine-month periods ended October 2, 2016 , and $44 ( $0.09 ) and $152 ( $0.30 ) for the three- and nine-month periods ended October 4, 2015 , respectively. No adjustment on any one contract was material to our unaudited Consolidated Financial Statements in the three- and nine-month periods ended October 2, 2016 , and October 4, 2015 . In the second quarter of 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 prescribes a single, common revenue standard that replaces most existing revenue recognition guidance in GAAP. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition. Several ASUs have been issued since the issuance of ASU 2014-09. These ASUs, which modify certain sections of ASU 2014-09, are intended to promote a more consistent interpretation and application of the principles outlined in the standard. The FASB has also issued two exposure drafts with technical corrections and updates intended to clarify ASU 2014-09. The exposure drafts are not expected to have a significant impact on the application of ASU 2014-09 and are anticipated to be issued as final ASUs prior to December 31, 2016. ASU 2014-09 is effective in the first quarter of 2018 for public companies. However, companies can elect to adopt one year earlier in the first quarter of 2017. The standard permits the use of either the retrospective or cumulative-effect transition method. Because the new standard will impact our business processes, systems and controls, we commenced our assessment of the standard during the second half of 2014 and developed a comprehensive change management project plan to guide the implementation. This project plan includes analyzing the standard’s impact on our contract portfolio, comparing our historical accounting policies and practices to the requirements of the new standard, and identifying potential differences from applying the requirements of the new standard to our contracts. With the assessment nearing completion, we plan to adopt the standard in the first quarter of 2017 using the retrospective transition method. We anticipate that the adoption of ASU 2014-09 will have primarily two impacts on our portfolio of contracts and our Consolidated Financial Statements. The majority of our long-term contracts will continue to recognize revenue and earnings over time as the work progresses because of the continuous transfer of control to the customer, generally using an input measure (e.g., costs incurred) to reflect progress. However, we will be precluded from using the reallocation method of recognizing adjustments in estimated profit on contracts discussed previously. The total impact of an adjustment in estimated profit recorded to date on a contract will be recognized in the period it is identified (cumulative catch-up method), rather than recognizing the impact of an adjustment prospectively over the remaining contract term. As a result, adjustments in contract estimates may be larger and likely more variable from period to period, particularly on our contracts of greater value and longer performance period (for example, in our Marine Systems group), and may introduce an element of variability to our operating results that we have not experienced using the reallocation method. Despite this variability, a contract’s cash flows and overall profitability at completion are the same under the cumulative catch-up method versus our current method of prospectively recognizing adjustments in estimate. Anticipated losses on contracts will continue to be recognized in the quarter they are identified. For our contracts for the manufacture of business-jet aircraft in the Aerospace group, we currently record revenue at two contractual milestones, green and outfitted aircraft delivery. Under ASU 2014-09, we will record revenue when control is transferred to the customer, generally when the customer accepts the fully outfitted aircraft. ASU 2014-09 will not change the total revenue or operating earnings recognized on our new aircraft contracts, only the timing of when those amounts are recognized. Numerous other contracts in our portfolio will be impacted by ASU 2014-09, due primarily to the identification of multiple performance obligations within a single contract. However, we do not anticipate that these impacts will be material to our Consolidated Financial Statements. We have assessed our 2015 operating results under ASU 2014-09. In our three defense groups, the assessment under ASU 2014-09 did not have a material impact on our results of operations. Our defense groups’ revenue and operating margin for 2015 were essentially unchanged. In our Aerospace group, the assessment under ASU 2014-09 increased revenue and operating margin by 4 percent and 40 basis points , respectively, as compared to 2015 operating results under existing GAAP. The increase in revenue and operating margin compared to as-reported 2015 operating results is due to the relationship between green and outfitted aircraft deliveries and the timing and mix of those aircraft deliveries. Because we delivered more outfitted aircraft than green aircraft in 2015, revenue and operating earnings were higher in 2015 under ASU 2014-09 versus under existing GAAP. The impact of ASU 2014-09 on our 2015 operating results may or may not be representative of the impact on subsequent years' results. As noted above, aircraft manufacturing revenue in our Aerospace group will be recognized when control is transferred to the customer, generally when the customer accepts the fully outfitted aircraft, which will depend on annual delivery rates. Moreover, as described above in our defense groups, use of the cumulative catch-up method of recognizing adjustments in estimated profits on our long-term contracts will require us to recognize the total impact of an adjustment in the period it is identified rather than prospectively over the remaining contract term as we have in the past. On our Consolidated Balance Sheet, long-term contracts will continue to be reported in a net asset (contracts in process) or liability (customer advances and deposits) position on a contract-by-contract basis at the end of each reporting period. Business-jet components in our Aerospace group will be reported in inventory until control of the aircraft transfers to the customer. The assessment of our December 31, 2015, Consolidated Balance Sheet under ASU 2014-09 resulted in some reclassifications among financial statement accounts, but these reclassifications did not materially change the total amount of net assets as of December 31, 2015. Once we adopt ASU 2014-09, we do not anticipate that our internal control framework will materially change, but rather that existing internal controls will be modified and augmented, as necessary, to consider our new revenue recognition policy effective January 1, 2017. As we implement the new standard, we have developed internal controls to ensure that we adequately evaluate our portfolio of contracts under the five-step model and accurately restate our prior-period operating results under ASU 2014-09. Discontinued Operations. In 2013, we settled litigation with the U.S. Navy related to the terminated A-12 aircraft contract in the company's former tactical military aircraft business. In connection with the settlement, we released some rights to reimbursement of costs on ships under contract at the time at our Bath, Maine shipyard. As we have progressed through the shipbuilding process, we have determined that the cost associated with this settlement is greater than anticipated. Therefore, in the third quarter of 2016, we recognized an $84 loss, net of taxes, to adjust the previously-recognized settlement value. In addition, in the first quarter of 2016, we recognized a final adjustment to the loss on the sale of a business further discussed in Note B. Accounting Standards Updates . The standards described below were issued by the FASB in 2016 and should be read in conjunction with the discussion of New Accounting Standards in our Annual Report on Form 10-K for the year ended December 31, 2015 . • ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. We adopted ASU 2016-09 in the second quarter of 2016. ASU 2016-09 impacted several aspects of our accounting for share-based payment transactions. The ASU requires that excess tax benefits and tax deficiencies be recognized as income tax expense or benefit in the Consolidated Statement of Earnings. Previously, these amounts were recognized directly to shareholders' equity. In the Consolidated Statement of Cash Flows, the excess tax benefit from equity-based compensation, previously classified as a financing activity, is now classified as an operating activity. Additionally, cash paid when directly withholding shares on an employee's behalf for tax withholding purposes is classified as a financing activity. The impact of the adoption in the nine -month period ended October 2, 2016 , was a tax benefit of approximately $60 . As this area of the ASU permits only prospective adoption, there was no impact on our 2015 Consolidated Financial Statements. In the Consolidated Statement of Cash Flows, the impact of the adoption in the nine -month period ended October 2, 2016 , was a $91 increase in net cash provided by operating activities and a corresponding $91 increase in net cash used by financing activities. The areas of the ASU that relate to the Consolidated Statement of Cash Flows were adopted retrospectively. We have restated our prior-period Consolidated Statement of Cash Flows accordingly, resulting in a $100 increase in net cash provided by operating activities and a corresponding $100 increase in net cash used by financing activities for the nine -month period ended October 4, 2015 . The other aspects of the ASU did not have a material impact on our results of operations, financial condition or cash flows. Several other ASUs issued by the FASB in 2016 are not yet effective, including the following: • ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires the recognition of lease rights and obligations as assets and liabilities on the balance sheet. Previously, lessees were not required to recognize on the balance sheet assets and liabilities arising from operating leases. The ASU also requires disclosure of key information about leasing arrangements. ASU 2016-02 is effective on January 1, 2019, using the modified retrospective method of adoption, with early adoption permitted. We are in the preliminary phases of assessing the effect of the ASU on our portfolio of leases. While this assessment continues, we have not yet selected a transition date nor have we yet determined the effect of the ASU on our Consolidated Financial Statements. • ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. ASU 2016-15 is effective retrospectively on January 1, 2018, with early adoption permitted. We have not yet determined the effect of the ASU on our Consolidated Financial Statements nor have we selected a transition date. We do not expect other ASUs issued by the FASB in 2016 to have a material effect on our Consolidated Financial Statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Acquisitions and Divestitures, Goodwill, and Intangible Assets	ACQUISITIONS AND DIVESTITURES, GOODWILL, AND INTANGIBLE ASSETS Acquisitions and Divestitures In 2016 , we acquired an aircraft management and charter services provider in our Aerospace group and a manufacturer of unmanned underwater vehicles (UUVs) in our Information Systems and Technology group. As the purchase prices of these acquisitions are immaterial, they are included in other investing activities in the unaudited Consolidated Statement of Cash Flows. We did not acquire any businesses in 2015 . The operating results of these acquisitions have been included with our reported results since the respective closing dates. The purchase prices of the acquisitions have been allocated to the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill. In 2015, we completed the sale of our axle business in our Combat Systems group and a commercial cyber security business in our Information Systems and Technology group. In the first quarter of 2016, we recognized a final adjustment to the loss on the sale of the axle business of $13 in discontinued operations. Goodwill The changes in the carrying amount of goodwill by reporting unit for the nine -month period ended October 2, 2016 , were as follows: Aerospace Combat Systems Information Systems and Technology Marine Systems Total Goodwill December 31, 2015 (a) $ 2,542 $ 2,591 $ 6,021 $ 289 $ 11,443 Acquisitions (b) 28 — 6 — 34 Other (c) 61 43 — — 104 October 2, 2016 $ 2,631 $ 2,634 $ 6,027 $ 289 $ 11,581 (a) Goodwill on December 31, 2015, in the Information Systems and Technology reporting unit is net of $2 billion of accumulated impairment losses.

Earnings Per Share [Abstract]
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. Basic weighted average shares outstanding have decreased throughout 2016 and 2015 due to share repurchases. See Note J for additional details of our share repurchases. Diluted EPS incorporates the additional shares issuable upon the assumed exercise of stock options and the release of restricted stock and restricted stock units (RSUs). The dilutive effect of stock options and restricted stock/RSUs increased because of the adoption of ASU 2016-09 in 2016. See Note A for additional detail of our adoption of this accounting standard. Basic and diluted weighted average shares outstanding were as follows (in thousands): Three Months Ended Nine Months Ended October 2, 2016 October 4, 2015 October 2, 2016 October 4, 2015 Basic weighted average shares outstanding 303,938 316,680 305,445 323,996 Dilutive effect of stock options and restricted stock/RSUs* 5,790 5,258 5,679 5,418 Diluted weighted average shares outstanding 309,728 321,938 311,124 329,414 * Excludes outstanding options to purchase shares of common stock because these options had exercise prices in excess of the average market price of our common stock during the period and therefore the effect of including these options would be antidilutive. These options totaled 4,622 and 4,080 for the three- and nine-month periods ended October 2, 2016 , and 2,034 and 1,605 for the three- and nine-month periods ended October 4, 2015 , respectively.

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE 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 October 2, 2016 , or December 31, 2015 . Our financial instruments include cash and equivalents, marketable securities and other investments; accounts receivable and 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 Sheet approximate their fair value. The following tables present the fair values of our other financial assets and liabilities on October 2, 2016 , and December 31, 2015 , and the basis for determining their fair values: Carrying Value Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) (b) Financial Assets (Liabilities) (a) October 2, 2016 Available-for-sale securities $ 179 $ 179 $ 93 $ 86 Derivatives (403 ) (403 ) — (403 ) Long-term debt, including current portion (3,923 ) (4,002 ) — (4,002 ) December 31, 2015 Available-for-sale securities $ 186 $ 186 $ 124 $ 62 Derivatives (673 ) (673 ) — (673 ) Long-term debt, including current portion (3,425 ) (3,381 ) — (3,381 ) (a) We had no Level 3 financial instruments on October 2, 2016 , or December 31, 2015 .

Income Taxes	INCOME TAXES Net Deferred Tax Asset. Our net deferred tax asset consisted of the following: October 2, 2016 December 31, 2015 Current deferred tax asset $ 8 $ 3 Current deferred tax liability (1,048 ) (829 ) Noncurrent deferred tax asset 1,152 1,272 Noncurrent deferred tax liability (88 ) (75 ) Net deferred tax asset $ 24 $ 371 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. The total amount of these tax liabilities on October 2, 2016 , is not material to our results of operations, financial condition or cash flow. We participate in the Internal Revenue Service (IRS) Compliance Assurance Process (CAP), a real-time audit of our consolidated federal corporate income tax return. The IRS has examined our consolidated federal income tax returns through 2015. 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 any unrecognized tax benefits on October 2, 2016 , 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. In addition, 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.

Contractors [Abstract]
Contracts In Process	CONTRACTS IN PROCESS Contracts in process represent recoverable costs and, where applicable, accrued profit related to long-term contracts less associated advances and progress payments. These amounts have been inventoried until the customer is billed, generally in accordance with the agreed-upon billing terms or upon shipment of products or rendering of services. Contracts in process consisted of the following: October 2, 2016 December 31, 2015 Contract costs and estimated profits $ 26,633 $ 20,742 Other contract costs 811 965 27,444 21,707 Advances and progress payments (22,231 ) (17,350 ) Total contracts in process $ 5,213 $ 4,357 Contract costs include primarily labor, material, overhead and, when appropriate, G&A expenses. Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. We record revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. 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	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.

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. On October 2, 2016 , we had no commercial paper outstanding, but we maintain the ability to access the commercial paper market in the future. We have $2 billion in committed bank credit facilities for general corporate purposes and working capital needs. These credit facilities include a $1 billion multi-year facility expiring in July 2018 and a $1 billion multi-year facility expiring in November 2020 . These facilities are required by credit 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 bank credit facilities are guaranteed by several of our 100 -percent-owned subsidiaries. We also have an effective shelf registration on file with the SEC that allows us to access the debt markets. In the third quarter of 2016 , we repaid $500 of fixed-rate notes on their maturity date with cash on hand. We also issued $1 billion of fixed-rate notes for general corporate purposes. Our financing arrangements contain a number of customary covenants and restrictions. We were in compliance with all covenants on October 2, 2016 .

Equity [Abstract]
Shareholders' Equity	SHAREHOLDERS' EQUITY Share Repurchases. Our board of directors authorizes management’s repurchase of shares of common stock on the open market from time to time. In the nine -month period ended October 2, 2016 , we repurchased 11.2 million of our outstanding shares for $1.5 billion . As some of these shares had not settled on October 2, 2016 , the associated $23 cash outflow will be reported in the fourth quarter. On October 2, 2016 , 8.4 million shares remained authorized by our board of directors for repurchase, approximately 3 percent of our total shares outstanding. We repurchased 19.3 million shares for $2.7 billion in the nine -month period ended October 4, 2015 . Dividends per Share. Dividends declared per share were $0.76 and $2.28 for the three- and nine-month periods ended October 2, 2016 , and $0.69 and $2.07 for the three- and nine-month periods ended October 4, 2015 , respectively. Cash dividends paid were $231 and $678 for the three- and nine-month periods ended October 2, 2016 , and $223 and $655 for the three- and nine-month periods ended October 4, 2015 , respectively. Accumulated Other Comprehensive Loss.

This was offset partially by pretax amortization of prior service credit of $56 and $54 for the nine-month periods ended October 2, 2016 , and October 4, 2015 , respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note M for additional details.

Derivative Instruments And Hedg

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 had $6.5 billion in notional forward exchange contracts outstanding on October 2, 2016 , and $7.2 billion on December 31, 2015 . We do not use derivatives for trading or speculative purposes. We recognize derivative financial instruments on the Consolidated Balance Sheet at fair value. See Note D for additional details. Foreign Currency Risk and Hedging Activities. 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 three -year average maturity of these instruments generally matches the duration of the activities that are at risk. We record changes in the fair value of derivative financial instruments in operating costs and expenses in the Consolidated Statement of Earnings or in other comprehensive loss (OCL) within the Consolidated Statement 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 OCL 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 Statement 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 Statement of Earnings for all derivative financial instruments, regardless of designation. Net gains and losses on derivative financial instruments recognized in earnings, including gains and losses related to hedge ineffectiveness, were not material to our results of operations for the three- and nine-month periods ended October 2, 2016 , and October 4, 2015 . Net gains and losses reclassified to earnings from OCL were not material to our results of operations for the three- and nine-month periods ended October 2, 2016 , and October 4, 2015 , and we do not expect the amount of these gains and losses 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 October 2, 2016 , or December 31, 2015 . 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 rising labor and commodity price risk, primarily on long-term fixed-price contracts. To the extent possible, we include terms in our contracts that are designed to protect us from these risks. 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 October 2, 2016 , we held $2.3 billion in cash and equivalents, but held no marketable securities. 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 end-of-period exchange rates, and statements of earnings at average exchange rates for each period. The resulting foreign currency translation adjustments are a component of OCL. We do not hedge the fluctuation in reported revenue and earnings resulting from the translation of these international operations' results into U.S. dollars. The negative impact of translating our non-U.S. operations’ revenue into U.S. dollars was not material to our results of operations for the three- and nine-month periods ended October 2, 2016 , or October 4, 2015 . In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material in the nine -month periods ended October 2, 2016 , and October 4, 2015 .

Commitments And Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Litigation In 2015, Electric Boat Corporation, a subsidiary of General Dynamics Corporation, received a Civil Investigative Demand from the U.S. Department of Justice regarding an investigation of potential False Claims Act violations relating to alleged failures of Electric Boat’s quality system with respect to allegedly non-conforming parts purchased from a supplier. In 2016, Electric Boat was made aware that it is a defendant in a lawsuit related to this matter filed under seal in U.S. district court. In May 2016, the Suspending and Debarring Official for the U.S. Department of the Navy issued a Show Cause Letter to Electric Boat requesting that Electric Boat respond to the official’s concerns regarding Electric Boat’s oversight and management with respect to its quality assurance systems for subcontractors and suppliers. Electric Boat responded to the Show Cause Letter and has been engaged in discussions with the official. Given the current status of these matters, we are unable to express a view regarding the ultimate outcome or, if the outcome is adverse, to estimate an amount or range of reasonably possible loss. Depending on the outcome of these matters, there could be a material impact on our results of operations, financial condition and cash flows. Additionally, various other claims and legal proceedings incidental to the normal course of business are pending or threatened against us. These other 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 other matters. However, based on information currently available, we believe any potential liabilities in these other 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 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 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 audits 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 the 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 on the circumstances, we periodically file requests for equitable adjustment (REAs) that are sometimes converted into claims. In some cases, these requests are disputed by our customer. We believe our outstanding modifications, REAs and claims will be resolved without material impact to our results of operations, financial condition or 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 billion on October 2, 2016 . In addition, from time to time and in the ordinary course of business, we contractually guarantee the payment or performance obligations of our subsidiaries arising under certain contracts. 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 45 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 outfitted 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 based generally on the number of months of warranty coverage remaining for the 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 Sheet. The changes in the carrying amount of warranty liabilities for the nine-month periods ended October 2, 2016 , and October 4, 2015 , were as follows: Nine Months Ended October 2, 2016 October 4, 2015 Beginning balance $ 465 $ 428 Warranty expense 85 128 Payments (72 ) (92 ) Adjustments (1 ) (1 ) Ending balance $ 477 $ 463

Compensation and Retirement Disclosure [Abstract]
Retirement Plans	RETIREMENT PLANS We provide defined-contribution benefits to eligible employees, as well as some defined-benefit pension and other post-retirement benefits. Net periodic defined-benefit pension and other post-retirement benefit cost for the three- and nine-month periods ended October 2, 2016 , and October 4, 2015 , consisted of the following: Pension Benefits Other Post-retirement Benefits Three Months Ended October 2, 2016 October 4, 2015 October 2, 2016 October 4, 2015 Service cost $ 44 $ 57 $ 3 $ 3 Interest cost 114 133 8 11 Expected return on plan assets (178 ) (174 ) (8 ) (8 ) Recognized net actuarial loss (gain) 84 110 (1 ) 2 Amortization of prior service credit (17 ) (17 ) (2 ) (1 ) Net periodic benefit cost $ 47 $ 109 $ — $ 7 Pension Benefits Other Post-retirement Benefits Nine Months Ended October 2, 2016 October 4, 2015 October 2, 2016 October 4, 2015 Service cost $ 132 $ 171 $ 8 $ 9 Interest cost 342 399 25 33 Expected return on plan assets (534 ) (522 ) (24 ) (24 ) Recognized net actuarial loss (gain) 252 329 (3 ) 5 Amortization of prior service credit (51 ) (51 ) (5 ) (3 ) Net periodic benefit cost $ 141 $ 326 $ 1 $ 20 Beginning in 2016, we refined the method used to determine the service and interest cost components of our net periodic benefit cost. Previously, the cost was determined using a single weighted-average discount rate derived from a yield curve developed from a portfolio of high-quality fixed-income investments with maturities consistent with the projected benefit payout period. Under the refined method, known as the spot rate approach, we use individual spot rates along the yield curve that correspond with the timing of each benefit payment. We believe this change provides a more precise measurement of service and interest costs by improving the correlation between projected cash outflows and corresponding spot rates on the yield curve. Compared to the previous method the spot rate approach decreased the service and interest components of our benefit costs slightly in 2016. We accounted for this change prospectively as a change in accounting estimate. 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 Sheet until the cost is allocable to contracts. See Note F for discussion of our deferred contract costs. For other plans, the amount allocated to contracts and included in revenue has exceeded the plans’ cumulative benefit cost. We have deferred recognition of these excess earnings to provide a better matching of revenue and expenses. These deferrals have been classified against the plan assets on the Consolidated Balance Sheet.

Summary Of Significant Accoun23

Summary Of Significant Accounting Policies (Policies)	9 Months Ended
	Oct. 02, 2016
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. Some prior-year amounts have been reclassified among financial statement accounts to conform to the current-year presentation. Consistent with defense industry practice, we classify assets and liabilities related to long-term 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 October 2, 2016 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 . 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 October 2, 2016 , and October 4, 2015 . 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, 2015 .
Revenue Recognition	Revenue Recognition. We account for revenue and earnings using the percentage-of-completion method. Under this method, we recognize contract costs and revenue 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 expected 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-related estimates regularly. We recognize adjustments in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of an adjustment in estimate is recognized prospectively over the remaining contract term. The net impact of adjustments in contract estimates on our operating earnings (and on a diluted per-share basis) totaled favorable adjustments of $44 ( $0.09 ) and $231 ( $0.48 ) for the three- and nine-month periods ended October 2, 2016 , and $44 ( $0.09 ) and $152 ( $0.30 ) for the three- and nine-month periods ended October 4, 2015 , respectively. No adjustment on any one contract was material to our unaudited Consolidated Financial Statements in the three- and nine-month periods ended October 2, 2016 , and October 4, 2015 . In the second quarter of 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 prescribes a single, common revenue standard that replaces most existing revenue recognition guidance in GAAP. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition. Several ASUs have been issued since the issuance of ASU 2014-09. These ASUs, which modify certain sections of ASU 2014-09, are intended to promote a more consistent interpretation and application of the principles outlined in the standard. The FASB has also issued two exposure drafts with technical corrections and updates intended to clarify ASU 2014-09. The exposure drafts are not expected to have a significant impact on the application of ASU 2014-09 and are anticipated to be issued as final ASUs prior to December 31, 2016. ASU 2014-09 is effective in the first quarter of 2018 for public companies. However, companies can elect to adopt one year earlier in the first quarter of 2017. The standard permits the use of either the retrospective or cumulative-effect transition method. Because the new standard will impact our business processes, systems and controls, we commenced our assessment of the standard during the second half of 2014 and developed a comprehensive change management project plan to guide the implementation. This project plan includes analyzing the standard’s impact on our contract portfolio, comparing our historical accounting policies and practices to the requirements of the new standard, and identifying potential differences from applying the requirements of the new standard to our contracts. With the assessment nearing completion, we plan to adopt the standard in the first quarter of 2017 using the retrospective transition method. We anticipate that the adoption of ASU 2014-09 will have primarily two impacts on our portfolio of contracts and our Consolidated Financial Statements. The majority of our long-term contracts will continue to recognize revenue and earnings over time as the work progresses because of the continuous transfer of control to the customer, generally using an input measure (e.g., costs incurred) to reflect progress. However, we will be precluded from using the reallocation method of recognizing adjustments in estimated profit on contracts discussed previously. The total impact of an adjustment in estimated profit recorded to date on a contract will be recognized in the period it is identified (cumulative catch-up method), rather than recognizing the impact of an adjustment prospectively over the remaining contract term. As a result, adjustments in contract estimates may be larger and likely more variable from period to period, particularly on our contracts of greater value and longer performance period (for example, in our Marine Systems group), and may introduce an element of variability to our operating results that we have not experienced using the reallocation method. Despite this variability, a contract’s cash flows and overall profitability at completion are the same under the cumulative catch-up method versus our current method of prospectively recognizing adjustments in estimate. Anticipated losses on contracts will continue to be recognized in the quarter they are identified. For our contracts for the manufacture of business-jet aircraft in the Aerospace group, we currently record revenue at two contractual milestones, green and outfitted aircraft delivery. Under ASU 2014-09, we will record revenue when control is transferred to the customer, generally when the customer accepts the fully outfitted aircraft. ASU 2014-09 will not change the total revenue or operating earnings recognized on our new aircraft contracts, only the timing of when those amounts are recognized. Numerous other contracts in our portfolio will be impacted by ASU 2014-09, due primarily to the identification of multiple performance obligations within a single contract. However, we do not anticipate that these impacts will be material to our Consolidated Financial Statements. We have assessed our 2015 operating results under ASU 2014-09. In our three defense groups, the assessment under ASU 2014-09 did not have a material impact on our results of operations. Our defense groups’ revenue and operating margin for 2015 were essentially unchanged. In our Aerospace group, the assessment under ASU 2014-09 increased revenue and operating margin by 4 percent and 40 basis points , respectively, as compared to 2015 operating results under existing GAAP. The increase in revenue and operating margin compared to as-reported 2015 operating results is due to the relationship between green and outfitted aircraft deliveries and the timing and mix of those aircraft deliveries. Because we delivered more outfitted aircraft than green aircraft in 2015, revenue and operating earnings were higher in 2015 under ASU 2014-09 versus under existing GAAP. The impact of ASU 2014-09 on our 2015 operating results may or may not be representative of the impact on subsequent years' results. As noted above, aircraft manufacturing revenue in our Aerospace group will be recognized when control is transferred to the customer, generally when the customer accepts the fully outfitted aircraft, which will depend on annual delivery rates. Moreover, as described above in our defense groups, use of the cumulative catch-up method of recognizing adjustments in estimated profits on our long-term contracts will require us to recognize the total impact of an adjustment in the period it is identified rather than prospectively over the remaining contract term as we have in the past. On our Consolidated Balance Sheet, long-term contracts will continue to be reported in a net asset (contracts in process) or liability (customer advances and deposits) position on a contract-by-contract basis at the end of each reporting period. Business-jet components in our Aerospace group will be reported in inventory until control of the aircraft transfers to the customer. The assessment of our December 31, 2015, Consolidated Balance Sheet under ASU 2014-09 resulted in some reclassifications among financial statement accounts, but these reclassifications did not materially change the total amount of net assets as of December 31, 2015. Once we adopt ASU 2014-09, we do not anticipate that our internal control framework will materially change, but rather that existing internal controls will be modified and augmented, as necessary, to consider our new revenue recognition policy effective January 1, 2017. As we implement the new standard, we have developed internal controls to ensure that we adequately evaluate our portfolio of contracts under the five-step model and accurately restate our prior-period operating results under ASU 2014-09.
Discontinued Operations	Discontinued Operations. In 2013, we settled litigation with the U.S. Navy related to the terminated A-12 aircraft contract in the company's former tactical military aircraft business. In connection with the settlement, we released some rights to reimbursement of costs on ships under contract at the time at our Bath, Maine shipyard. As we have progressed through the shipbuilding process, we have determined that the cost associated with this settlement is greater than anticipated. Therefore, in the third quarter of 2016, we recognized an $84 loss, net of taxes, to adjust the previously-recognized settlement value. In addition, in the first quarter of 2016, we recognized a final adjustment to the loss on the sale of a business further discussed in Note B.
Accounting Standards Updates	Accounting Standards Updates . The standards described below were issued by the FASB in 2016 and should be read in conjunction with the discussion of New Accounting Standards in our Annual Report on Form 10-K for the year ended December 31, 2015 . • ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. We adopted ASU 2016-09 in the second quarter of 2016. ASU 2016-09 impacted several aspects of our accounting for share-based payment transactions. The ASU requires that excess tax benefits and tax deficiencies be recognized as income tax expense or benefit in the Consolidated Statement of Earnings. Previously, these amounts were recognized directly to shareholders' equity. In the Consolidated Statement of Cash Flows, the excess tax benefit from equity-based compensation, previously classified as a financing activity, is now classified as an operating activity. Additionally, cash paid when directly withholding shares on an employee's behalf for tax withholding purposes is classified as a financing activity. The impact of the adoption in the nine -month period ended October 2, 2016 , was a tax benefit of approximately $60 . As this area of the ASU permits only prospective adoption, there was no impact on our 2015 Consolidated Financial Statements. In the Consolidated Statement of Cash Flows, the impact of the adoption in the nine -month period ended October 2, 2016 , was a $91 increase in net cash provided by operating activities and a corresponding $91 increase in net cash used by financing activities. The areas of the ASU that relate to the Consolidated Statement of Cash Flows were adopted retrospectively. We have restated our prior-period Consolidated Statement of Cash Flows accordingly, resulting in a $100 increase in net cash provided by operating activities and a corresponding $100 increase in net cash used by financing activities for the nine -month period ended October 4, 2015 . The other aspects of the ASU did not have a material impact on our results of operations, financial condition or cash flows. Several other ASUs issued by the FASB in 2016 are not yet effective, including the following: • ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires the recognition of lease rights and obligations as assets and liabilities on the balance sheet. Previously, lessees were not required to recognize on the balance sheet assets and liabilities arising from operating leases. The ASU also requires disclosure of key information about leasing arrangements. ASU 2016-02 is effective on January 1, 2019, using the modified retrospective method of adoption, with early adoption permitted. We are in the preliminary phases of assessing the effect of the ASU on our portfolio of leases. While this assessment continues, we have not yet selected a transition date nor have we yet determined the effect of the ASU on our Consolidated Financial Statements. • ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. ASU 2016-15 is effective retrospectively on January 1, 2018, with early adoption permitted. We have not yet determined the effect of the ASU on our Consolidated Financial Statements nor have we selected a transition date. We do not expect other ASUs issued by the FASB in 2016 to have a material effect on our Consolidated Financial Statements.
