North American AJ Savage

The North American AJ Savage, later designated A-2 Savage, was a carrier-based medium bomber built for the United States Navy.

The aircraft was designed shortly after World War II to carry atomic bombs and this meant that the bomber was the heaviest aircraft thus far designed to operate from an aircraft carrier.

It was powered by two piston engines and a turbojet buried in the rear fuselage.

The AJ-1 first became operational in 1950 and several were based in South Korea during 1953 as a deterrent against the Communists.

143 built, this includes 3 prototypes, of these 30 were reconnaissance aircraft.
