AMENDMENT TO RETIREMENT BENEFIT AGREEMENT

Exhibit 10.2

AMENDMENT TO RETIREMENT BENEFIT AGREEMENT

This Amendment, dated as of June 7, 2007, amends the Retirement Benefit Agreement dated as of March 4, 1998 between General Dynamics Corporation (the “Corporation”) and David A. Savner (“the Executive”) (the “Retirement Benefit Agreement” or the “Agreement”).

“3. AMOUNT OF SUPPLEMENTAL RETIREMENT BENEFIT.

Except as described in Section 4, upon termination of the Executive’s employment with the Corporation, the Executive shall be eligible to receive a Supplemental Retirement Benefit hereunder calculated under the Final Average Benefit Formula of the Retirement Plan increased to reflect the addition of five (5) years of Plan Membership (as defined in the Retirement Plan) to the Executive’s actual period of Plan Membership while an Executive and then reduced by any payments that may be payable under the Retirement Program. This offset shall be calculated based on the normal lifetime benefits payable under the terms of this Retirement Benefit Agreement and the Retirement Program prior to the election of any optional forms for payment of retirement benefits.”

“4. ELIGIBILITY FOR SUPPLEMENTAL RETIREMENT BENEFITS.

Notwithstanding anything in this Agreement to the contrary, no Supplemental Retirement Benefit shall be paid hereunder (and any Supplemental Retirement Benefit currently being paid to the Executive shall cease) if, in the sole opinion of the Compensation Committee, the Executive: (a) is discharged for causing harm to the Corporation (financial, reputation, or product), through: (i) an act or acts of personal dishonesty, (ii) conviction of a felony related to the Corporation, (iii) material violation of General Dynamics’ standards of business ethics and conduct, or (iv) individually filing, assisting or participating in a lawsuit against the Corporation, or (b) is subsequently employed either as an employee or an independent contractor (other than as a member of a law firm, a director on the board of directors of a charitable organization, or a director on the board of directors of a company that does not compete with the Corporation or any of its subsidiaries) without prior Compensation Committee approval which approval shall not be unreasonably withheld.”

“5. TIME AND FORM OF PAYMENT.

The Supplemental Retirement Benefit shall be paid in the form of a single life annuity commencing on the first day of the month next following the executive’s termination of employment, or in any other annuity form that is (a) available under the Retirement Plan, (b) elected by the Executive by written notice transmitted to the Corporation at least 30

days prior to the date on which payment of his benefit would otherwise commence hereunder and (c) is actuarially equivalent to the single life annuity to which he would otherwise be entitled (as determined pursuant to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). The applicable single-life annual benefit shall then be converted to the alternate form elected by the application of the actuarial factors used for converting benefits under the Retirement Plan at the time the retirement benefit is to commence. Notwithstanding the foregoing, in the event the receipt by the Executive of any payment hereunder within six (6) months of termination of employment would cause the Executive to incur any tax or penalty under Section 409A of the Code, then such payment shall be made six (6) months following the Executive’s termination of employment. Any amount the payment of which is delayed in accordance with the preceding sentence shall be paid with interest at an annual rate equal to the prime rate (as determined by the Northern Trust Company of Chicago from time to time) from the date on which such amount would otherwise have been paid until the actual date of payment.”

“6. SURVIVOR BENEFIT IN CASE OF DEATH PRIOR TO PAYMENT OF BENEFITS.

If the Executive dies after the date of this Agreement but prior to commencement of the Supplemental Retirement Benefit hereunder, and at the time of his death he would have been entitled to a Supplemental Retirement Benefit in the event of his involuntary termination, then his spouse shall be entitled to receive a “Pre-Retirement Surviving Spouse Annuity” as provided in the Retirement Plan (currently defined as a 100% Contingent Annuity) for her life. The amount of the Pre-Retirement Surviving Spouse Annuity payable under this Agreement shall equal the amount to which the Executive would have been entitled as a single life annuity under Section 5 hereof had he terminated employment immediately prior to his death. Payment of this benefit shall commence on the first day of the month next following the Executive’s death.”

“7. ADDITIONAL TERMINATION BENEFITS.
