The FB-22 is a proposed United States Air Force (USAF) bomber aircraft, designed as a derivative of the F/A-22 and intended to fulfill a USAF requirement of an interim bomber to replace the B-1B Lancer and precede a next-generation strike aircraft entering service after 2037. Secretary of the Air Force James Roche is said to be one of its strongest proponents.

The FB-22 differs from the original F/A-22 design significantly. A lengthened fuselage provides greater fuel capacity and a much larger internal weapons bay, more suitable for long range attack missions. The elongated delta wing and lack of any tailplanes coupled with a possible change to the General Electric/Rolls-Royce F136 engines would allow for a higher top-speed, sacrificing some maneuverability for better bomber performance. At first glance the FB-22 design might appear similar to the X-44 MANTA, however the FB-22 would rely on wing control surfaces and likely have fixed engine nozzles.
