Recent Events - Deregistration

This Post-Effective Amendment relates to the Registration Statement on Form S-8 (333-113401) filed by Anteon International Corporation (the “Company”) with the Securities and Exchange Commission on March 8, 2004 (the “Registration Statement”) which registered 1,200,000 shares of Company common stock, par value $.01 (the “Securities”) relating to the Company’s Employee Stock Purchase Plan (the “Plan”). The Company has issued 103,399 Securities under this Registration Statement.

The Company, General Dynamics Corporation (“General Dynamics”) and Avenger Acquisition Corporation (“Merger Sub”) entered into an Agreement and Plan of Merger dated December 13, 2005 (the “Merger Agreement”) pursuant to which, among other things, the Company would be merged with and into Merger Sub, an indirect, wholly-owned subsidiary of General Dynamics, and all outstanding shares of Company common stock that were issued and outstanding immediately prior to the effective time of the merger (other than shares of Company common stock owned by the Company, General Dynamics or Merger Sub or any of their respective subsidiaries and other than dissenting shares), together with any associated rights under the Company’s rights agreement, would be cancelled and automatically converted into the right to receive per share of Company common stock an amount in cash equal to $55.50, without interest, less any required withholding taxes (these actions being collectively referred to as the “Merger”).

On March 3, 2006, the Company held a special meeting of stockholders at which the stockholders adopted the Merger Agreement and the transactions contemplated thereby. On June 8, 2006, the Merger closed in accordance with the terms of the Merger Agreement.

As a result of the Merger, which was consummated on June 8, 2006, the Company has terminated all offerings of its common stock and other securities, including the Securities, pursuant to its existing registration statements, including the Registration Statement. In accordance with the foregoing, the Company hereby removes from registration all the Securities under the Registration Statement which remain unissued and unsold as of the date hereof.
