The North American Aviation XA2J "Super Savage" was a prototype carrier-based attack aircraft built in the early 1950s.

It had a crew of three: pilot, co-pilot/bombardier, and gunner who sat in a pressurised cabin in the nose of the aircraft.

Up to 10,500 lb (4,800 kg) of bombs could be carried in a large enclosed bomb-bay in the center fuselage, while the planned defensive armament was a remotely controlled tail turret with two 20 mm cannon.

[3] Construction of two prototypes started 1 October 1948, but due to delays developing the engines, the first flight was not until 4 January 1952.

The T40 engine was an ambitious engine design with two power sections, (the T38 was developed from the T40 to assist in its development, by using a single power section with extension shaft and gearbox),[5] driving two large contra-rotating propellers through a combining gearbox.
