The first production General Dynamics FB-111A supersonic strategic bomber successfully completed a 30-minute maiden flight at Carswell Air Force Base, Fort Worth, Texas. The FB-111A differed from the F-111A fighter bomber with the substitution of a larger wing, originally designed for the F-111B, giving the bomber a 7 foot (2.134 meter) increase in wingspan. The landing gear was strengthened, the bomb bay enlarged, and it had more powerful engines.
