The North American AJ Savage was a US Navy strategic bomber in service from 1949 to the early 1960s. It was equipped with two piston engines and a jet engine.
The North American AJ was planned as a three-seat carrier-based bomber . The aircraft had two Pratt & Whitney -R-2800-48- radial engines with 2,535 hp each, which were conventionally attached under the wings. In addition, a single Allison J33 A-10 jet engine was added in the rear fuselage. The wings were designed in a shoulder-wing design so that the landing gear could be kept relatively short, but the propellers still had sufficient distance to the flight deck. The prototype made its maiden flight on July 3, 1948, and the model entered service in 1949. 55 AJ-1 and AJ-2 bombers and 30 AJ-2P reconnaissance aircraft were built.
When the bomber role was taken over by other models, the remaining machines were converted into tankers. To do this, the jet engine was removed and an air refueling system with a hose funnel was installed instead. This made the AJ the first tanker in the US Navy.
With the rename products all aircraft in the armed forces of the United States in 1962, the term of the few remaining machines in modified A-2 Savage .
One version, the A2J Super Savage, with two Allison T40 propeller turbines each producing 5,172 hp, did not get beyond the prototype stage. The first machine flew for the first time on January 4, 1952, the second not at all.
