Vought Model 1600/1601/1602 - Navalized F-16 Fighting Falcon Competitor in the Navy Air Combat Fighter competition, losing to the McDonnell Douglas F/A-18 Hornet in 1975. Lacking experience building carrier aircraft, General Dynamics teamed up with Vought - if the design had won, Vought would have built it. Major design changes from the F-16 included structural strengthening, an arrestor hook, rails for AIM-9 Sidewinder missiles on the side of the air intake, and a more robust undercarriage. The 1600, 1601, and 1602 were all designed for use with different engines (The Pratt & Whitney F401, Pratt & Whitney F100, and General Electric F101, respectively). The project never progressed past the design stage.
