General Dynamics Corporation (GD) is an American aerospace and defense multinational corporation formed by mergers and divestitures. It is the world's fifth-largest defense contractor based on 2012 revenues. The company ranked No. 99 in the 2018 Fortune 500 list of the largest United States corporations by total revenue. It is headquartered in West Falls Church, Fairfax County, Virginia.
The company has changed markedly in the post–Cold War era of defense consolidation. It has four main business segments: Marine Systems, Combat Systems, Information Systems Technology, and Aerospace. General Dynamics' former Fort Worth Division manufactured the F-16 Fighting Falcon until 1993, which was one of the Western world's most-produced jet fighters. Production was sold to Lockheed Martin, but GD re-entered the airframe business in 1999 with its purchase of Gulfstream Aerospace.
