The YA-7F "A-7 Plus" (originally A-7 Strikefighter) was developed in response to an Air Force request for an improved fast close air support and ground attack aircraft. Two A-7Ds were sent back to the contractor for extensive modifications. The new design called for a new engine, either the Pratt & Whitney F100 or General Electric F110. Initially the F100 was installed. To accommodate the new engine, the fuselage was lengthened about 4 feet. New fuselage sections were inserted in both the forward and aft fuselage -- a 30-inch section in front of the wing and an 18-inch section behind the wing. The wing was strengthened and fitted was new augmented flaps, leading edge extensions and automatic maneuvering flaps. The vertical stabilizer height was increased about 10 inches.

Besides the engine and structural changes, the A-7 Plus featured an updated avionics package including a Forward Looking Infrared system.

The A-7 Plus project was begun in the mid 1980s and the actual modifications started in 1987. The first flight of the YA-7D was Nov. 29, 1989. The flight test program continued through 1990 with good results; however, the USAF decided to use F-16s for the CAS/ground attack mission and canceled the A-7 Plus program.
