The Participants and Administrator

General Dynamics Corporation Savings and Stock Investment Plan (Plan 5.0):

We have audited the accompanying statements of net assets available for benefits of the General Dynamics Corporation Savings and Stock Investment Plan (Plan 5.0) (the Plan) as of December 31, 2009 and 2008, and the related statement of changes in net assets available for benefits for the year ended December 31, 2009. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2009 and 2008, and the changes in net assets available for benefits for the year ended December 31, 2009 in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule – Schedule H, Line 4a – Schedule of Delinquent Participant Contributions as of December 31, 2009 is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, as amended. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

GENERAL DYNAMICS CORPORATION

SAVINGS AND STOCK INVESTMENT PLAN (PLAN 5.0)

Notes to Financial Statements

December 31, 2009 and 2008

(1) Plan Description

The following description of the General Dynamics Corporation Savings and Stock Investment Plan (Plan 5.0) (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

(a) General

The Plan is a defined-contribution plan covering eligible salaried employees of General Dynamics Corporation (the Company or the Plan Sponsor). Employees subject to a collective bargaining agreement are not eligible to participate in this Plan. Such employees are primarily eligible to participate in the General Dynamics Corporation Savings and Stock Investment Plan for Represented Employees (Represented Plan). The Plan is one of four plans that comprise the General Dynamics Corporation Savings and Stock Investment Plan Master Trust (Master Trust).

(b) Plan Administration

The Northern Trust Company (TNT) holds the Plan’s assets as the Plan’s trustee. Hewitt Associates, LLC (Hewitt) is the Plan’s recordkeeper.

(c) Contributions

Contribution percentages range from 1 percent to 50 percent of eligible compensation on a pre-tax basis, up to the statutory limits defined by the Internal Revenue Code (IRC). The Plan has an employer match rate of up to 100 percent of the first 4 percent of eligible compensation contributed to the Plan and 50 percent of the next 2 percent of eligible compensation contributed to the Plan. The Plan is intended to be a safe-harbor plan as defined in the IRC.

(d) Participant Accounts

Each participant directs his or her contributions to be invested in various funds. Changes to investment elections can be made according to rules set by the Plan Sponsor. Each participant’s account is credited with the participant’s contribution and allocations of (a) the Company’s contribution and (b) Plan earnings, less an allocation of administrative expenses. The benefit to which a participant is entitled is the vested balance of his or her account.

(e) Vesting

Participants are eligible to participate in the Plan upon hire. Participants’ contributions, Company matching contributions made on or subsequent to January 1, 2007, and earnings thereon vest immediately. Vesting in Company matching contributions made prior to January 1, 2007, varies by business unit, but does not exceed three years.

(f) Participant Loans

The Plan permits active participants to borrow the lesser of $50,000 or 50 percent of the vested amount in their accounts (subject to limits defined in the Plan document and the IRC). Participants are permitted to repay the loan by regular payroll deductions over a period of up to five years. Loans

Notes to Financial Statements

December 31, 2009 and 2008

are issued at the prime rate of interest. The Plan also offers primary residence loans (up to 20 years), which are secured by the balance in the participants’ account. Participant loans outstanding at December 31, 2009, bear interest at rates that range from 3.3 percent to 10.5 percent. Participant loans are valued based on amortized cost, which is the remaining unpaid principal balance plus any accrued but unpaid interest. This amortized cost approximates fair value.

(g) Payment of Benefits

On termination of service due to death, disability, or retirement, a participant (or designated beneficiary) may elect to (a) receive a lump-sum amount equal to the value of the participant’s vested interest in his or her account, (b) roll over the value of the participant’s vested interest in his or her account into another qualified plan, (c) receive annual installment payments over a specified period or in specified amounts, or (d) receive a partial distribution of his or her total account balance. Participants may also receive hardship withdrawals under the provisions of the IRC in a lump-sum payment. Active participants may be eligible to receive in-service or hardship withdrawals or withdrawals allowed under the IRC for participants that reach age 59 ¹/2.

(h) Forfeited Accounts

During the year ended December 31, 2009, participants’ forfeited nonvested accounts totaled $7,750. These amounts were used to reduce employer contributions. The Plan’s forfeiture balance at December 31, 2009 was $7,154 and consists of employer contributions credited back to the Plan for nonvested participants who terminated employment with the Plan Sponsor. These amounts will be used to reduce employer contributions in 2010.

(i) Administrative Expenses

The Master Trust generally pays the administrative expenses of the Plan. The Plan document provides that the Company may reimburse the Plan for administrative expenses. The Company did not reimburse any administrative expenses in 2009.

Company employees perform certain administrative functions that are not reimbursed by the Master Trust. The Plan document provides that the Company is entitled to reimbursement for certain costs incurred on behalf of the Plan. The Company did not seek reimbursement for these costs in 2009.

Administrative expenses may be specifically identified to the four plans that participate in the Master Trust, or these expenses may be attributable to the Master Trust in general. Specifically identified fees of the Plan for 2009 were $989,702 and are reflected as administrative expenses in the Statement of Changes in Net Assets Available for Benefits. General expenses (primarily investment management and trustee fees) of the Master Trust in 2009 were $2,310,406. A portion of these expenses is allocated to the Plan using the percentage of the Plan’s interest in the net assets of the Master Trust. For the year ended December 31, 2009, approximately $687,000 of general expenses were allocated to the Plan and included as a reduction of participation in the income of the Master Trust.

Notes to Financial Statements

December 31, 2009 and 2008

(j) Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

(2) Summary of Significant Accounting Policies

(a) Basis of Accounting

The accompanying financial statements are prepared under the accrual basis of accounting.

(b) Investment Valuation and Income Recognition

The Plan’s investments are stated at fair value with the exception of fully benefit-responsive investment contracts (referred to herein as Guaranteed Insurance Contracts or GICs), which are adjusted from fair value to contract value.

Purchases and sales of investments are recorded on the trade date. Investment income consists of dividend income, interest income, net appreciation (depreciation) in the fair value of investments, capital gains distributions, and realized gains (losses). Dividends are recognized on the ex-dividend date, the date on which an entity or an individual must own the stock to receive the pending dividend. Interest income is recorded on an accrual basis. Net appreciation (depreciation) in the fair value of investments represents the net unrealized changes in the market value of investments during the period.

(c) Payment of Benefits

Benefits are recorded when paid.

(d) Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

(3) Tax Status

The Plan applied on January 31, 2007 for a favorable tax determination from the Internal Revenue Service (IRS) indicating that the Plan is a qualified plan under Section 401(a) of the IRC and is exempt from federal income tax under Section 501(a) of the IRC. Although the application for favorable tax determination is still pending, the Plan Sponsor and the Plan’s tax counsel believe the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC.

General

The Plan’s investments are held by the Master Trust, which was established for the investment of the Plan’s assets and the assets of General Dynamics Corporation Savings and Stock Investment Plan (Plan 3.0), General Dynamics Corporation Savings and Stock Investment Plan (Plan 4.5), and the Represented Plan, collectively the Plans.

Investments in common collective trusts (at fair value):
Collective Daily S&P 500 Equity Fund		1,147,482,047		873,237,059

Guaranteed Investment Contracts

A portion of the assets in the Master Trust are invested in fully benefit-responsive investment contracts with MetLife Insurance Company (MetLife), whose credit rating from A.M. Best at December 31, 2009 was aa-. The assets of these GICs are invested in a MetLife account, and MetLife guarantees the principal and accrued interest, based on contractually-defined interest rates, for participant-initiated withdrawals as long as the contract remains active. Interest is credited to the contract at interest rates that reflect the performance of the underlying portfolio. MetLife resets the interest rate semi-annually based on the market value of the portfolio and the guaranteed value over the weighted average duration of the investments. The minimum interest crediting rate is zero percent. Participants will receive the principal and accrued interest upon withdrawal for events such as transfers to other Plan investment options or payments for retirement, termination of employment, disability, death and in-service withdrawals as permitted by the Plan.

Certain events, including premature termination of the GICs, plant closings, layoffs, plan terminations, bankruptcy, mergers and early retirement incentives, could limit the ability of the Plan to transact open investments at contract value. The occurrence of these events is not considered probable.

The investments shown in the accompanying Statements of Net Assets Available for Benefits include these fully benefit-responsive investment contracts at fair value with a corresponding adjustment to reflect these investments at contract value. Contract value represents contributions made under the contract, plus interest at the contract rate, less funds used to pay Plan benefits, excluding the effect of any loaned securities.

Notes to Financial Statements

December 31, 2009 and 2008

The contract value of the Master Trust’s GICs at December 31, 2009 and 2008 was $2,266,160,461 and $2,204,870,320, respectively, as compared to the fair value of $2,287,310,275 and $2,139,467,297, respectively. The Plan has recognized no reserves against contract value for credit risk of the contract issuers or other matters. The average yield and crediting interest rates ranged from 2.70 percent to 3.00 percent for 2009 and 2008.

Securities Lending

A portion of the Master Trust’s investments is used to engage in securities lending. The securities on loan and related collateral are valued daily to ensure adequate collateralization levels in relation to the securities on loan. The loaned security is delivered to the borrower, and collateral is received by TNT either simultaneously or in advance of security delivery. The total market value of collateralized securities on loan from the Master Trust at December 31, 2009 and 2008 was $701,981,323 and $354,036,212, respectively. Net income generated for the Master Trust from securities lending activities for the year ended December 31, 2009, was $1,537,416.

Fair Value Determination

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principle 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 under U.S. GAAP:

• Level 1 – Quoted prices (unadjusted) in active markets for identical investments.

General Dynamics Corporation Common Stock, Investments in Equity Securities, Units of Registered Investment Companies, and Equity Securities on Loan:

General Dynamics Corporation common stock, investments in equity securities and units of registered investment companies are valued using quoted prices in an active market. The fair value of equity securities on loan is based on the underlying securities on loan, which are comprised of equity securities valued using quoted prices in an active market.

• Level 2 – Inputs other than quoted prices that are observable to the market participant for the asset, or quoted prices in a market that is not active.

Guaranteed Investment Contracts, Units of Common Collective Trusts, Fixed Income Securities and Other Securities on Loan:

GICs and common collective trusts are private investment securities valued using the Net Asset Value (NAV) provided by the Plan’s trustee. The NAV is quoted on a private market that is not active. However, the unit price is primarily based on underlying investments that are traded on an active market. Fixed income securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. The fair value of other securities on loan is based on the value of the underlying GICs and fixed income securities on loan, which are determined consistent with the descriptions above for determining the fair value of GICs and fixed income securities.

• Level 3 – Inputs are unobservable to the market participant.

There are no Master Trust investments classified as Level 3 investments.

The valuation methods described above may produce a fair value calculation that is not indicative of a net realizable value or reflective of future fair values. Furthermore, although the Plan Sponsor believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of financial instruments could result in a different fair value measurement at the reporting date.

(5) Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended. In the event the Plan is terminated, each participant will automatically become vested in his or her unvested Company contributions. Each participant will receive payments based on the specific dollar amounts and shares of the Company’s common stock in his or her account.

To reduce interest rate risk, the Master Trust has entered into futures contracts that serve to adjust the duration of fixed-income assets. The futures contracts the Master Trust enters into are generally contracts to purchase U.S. Treasury or Agency Bonds, Notes, or Bills at a fixed price on a set date in the future, generally during the next three to six months. The derivatives are settled daily. As a result, the Master Trust pays or receives cash daily for changes in the market price of these instruments, with gains or losses reflected in investment income. Total mark-to-market losses of $1,053,299 were included in the net investment income of the Master Trust as a component of realized losses in fixed-income securities for the year ended December 31, 2009. The Master Trust had no derivative instruments designated as cash flow or fair value hedges during 2009 or 2008.

(7) Party-in-Interest Transactions

The Plan may, at the discretion of the Plan’s participants or via the Company match, invest through the Master Trust an unlimited amount of its assets in the Company’s common stock. The Master Trust held 36,067,226 and 34,217,554 shares of the Company’s common stock as of December 31, 2009 and 2008, respectively. Dividends earned by the Master Trust on the Company’s common stock were $52,731,950 for the year ended December 31, 2009.

The Plan also invests through the Master Trust in the COLTV Short-Term Investment Fund, the COLTV Daily S&P 500 Equity Fund, and the COLTV Daily Russell 2000 Fund. These funds are managed by TNT, a party-in-interest to the Plan. The following table summarizes the shares held by the Master Trust in these funds at December 31, 2009 and 2008:
