       ANTEON PROVIDES HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT UPDATE

FAIRFAX, VA, FEBRUARY 7, 2006 - Anteon International Corporation (NYSE: ANT),
announced today that General Dynamics Corporation (NYSE: GD) has, after
consultation with Anteon, voluntarily withdrawn its pre-merger notification and
report form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
relating to the previously announced proposed merger between Anteon and an
indirect, wholly-owned subsidiary of General Dynamics. Anteon anticipates that
General Dynamics will refile its pre-merger notification and report form on or
about Wednesday, February 8, 2006. The refiling is a procedural step to provide
the staff at the Antitrust Division of the United States Department of Justice
with additional time to review the information submitted by Anteon and General
Dynamics. Anteon still anticipates that the transaction will close no later than
the end of the second quarter of 2006.
