In 1972, Vought modified the first TF-41-powered A-7E (BuNo 156801) as a tandem, two-seat combat trainer demonstrator. The two-seater flew for the first time on August 19, 1972, piloted by John Konrad.

After demonstrating the two-seat Corsair II at various naval air stations, Vought was awarded a contract to modify 60 TF30-powered Corsair IIs (24 A-7Bs and 36 A-7Cs) into two-seat trainers, to be designated TA-7C. The first converted TA-7C flew for the the first time on December 17, 1976 and was delivered to the Navy on January 31, 1977. The TA-7Cs were delivered to VA-122 and to VA-174.
