GENERAL DYNAMICS COMPLETES ACQUISITION
OF GULFSTREAM AEROSPACE CORPORATION

SHAREHOLDERS OVERWHELMINGLY APPROVE MERGER

FALLS CHURCH, VA - General Dynamics (NYSE: GD) and Gulfstream Aerospace
Corporation (NYSE: GAC) announced today that they have completed the merger of
their two companies. The transaction creates a company of 38,000 employees and
estimated 1999 sales of $8.2 billion, with leading market positions in business
aviation, land and amphibious combat systems, shipbuilding and marine systems,
and information systems.

      Shareholders of both companies voted overwhelmingly in favor of the
transaction at separate meetings held this morning in New York and Falls Church,
Virginia. The two companies had announced on May 17, 1999, their agreement for
General Dynamics to acquire Gulfstream in a one-for-one stock swap. The value of
the transaction is approximately $4.8 billion, based on General Dynamics' July
29, 1999, closing price of $66.125 per share. Gulfstream's final day of trading
is today; it closed yesterday at $66.125 per share. General Dynamics expects to
issue approximately 72.2 million shares of stock to complete the transaction.

      Gulfstream, a leading designer, developer, manufacturer and marketer of
large cabin and ultra-long range business aircraft, is now a wholly owned
subsidiary of General Dynamics. It will retain its name and will continue to be
based in Savannah, Georgia. No major changes are planned for existing
management, work force, operations or facilities.

      "This is a great deal for the shareholders of both companies, and
we're proud to welcome Gulfstream to General Dynamics," said Nicholas
D. Chabraja, General Dynamics chairman and

chief executive officer. "The transaction is immediately and strongly accretive
to General Dynamics' earnings and cash flow. Gulfstream is a solid and well-run
business, and an excellent strategic fit. Quite simply, Gulfstream makes the
best business aircraft in the world - and we believe that it will reach its full
potential for significant growth as part of this company. Together, we will
leverage our complementary technical, manufacturing and marketing expertise to
continue to deliver outstanding financial performance in the years to come."

      Beginning in the third quarter, Gulfstream will record financial results
as General Dynamics' fourth major business group, to be called Aerospace. The
other three groups are Marine Systems, Combat Systems, and Information Systems
and Technology. Gulfstream had 1998 revenues of $2.4 billion and earnings of
$225.3 million; it ended the second quarter of 1999 with a $3.9 billion backlog
of 122 aircraft. General Dynamics had 1998 sales of $5 billion and earnings of
$542 million; it ended the second quarter of 1999 with a total backlog of $14.1
billion.
