General
            Dynamics was formed in 1952 with the purchase by the Electric
            Boat Company of Convair and Canadair.
            The only two aircraft known exclusively as General
            Dynamics products are the F-111 Aardvark of 1964 and the F-16
            Fighting Falcon of 1974.  After these two aircraft, the company
            began selling its aviation assets.
            Canadair was sold to the Canadian Government in
            1976.
             Cessna was purchased in 1985 and then
            sold to Textron in 1992.
            In 1993, the Fort Worth Division was sold to Martin
            Aircraft effectively getting General Dynamics out of the
            airframe business.  The company focused on its Combat Systems,
            Information Systems and Marine Systems divisions.
            General Dynamics re-entered the aerospace business
            with the acquisition of Gulfstream in 1999.
