The North American Aviation A2J "Super Savage" was a prototype carrier-based attack aircraft built in the early 1950s developed from the smaller AJ Savage.

Design and development

The A2J was intended to replace the AJ Savage which was deficient in performance and was a less than satisfactory carrier plane. [Miller, Jerry, "Nuclear Weapons and Aircraft Carriers," Washington D.C., Smithsonian institution Press, 2001, pgs. 90-99, ISSBN 1-56098-944-0] It was essentially an 'enlarged' AJ Savage with the two reciprocating engines replaced with two Allison T40 turboprop engines and removal of the tail-mounted turbojet. Construction of two prototypes started 1 October 1948. but due to delays developing the engines, the first flight was not until 4 January 1952. [Wagner, Ray, "American Combat Planes," third edition, Garden City, NY, Doubleday & Company, 1982, pgs. 389-490, ISBN 0-385-13120-8] The competing XA3D, the prototypes of which were ordered the year after construction had began on the A2J prototypes, first flew in October 1952. The A3D had far superior performance, and that doomed the A2J.

The root cause for the failure of the A2J was the protracted development and poor reliability of the Allison T40 engines. The T40 engine was an advanced engine design of joining two T38 turboprop engines to drive two large contra-rotating propellers through a combining gearbox, proved to be very unreliable. The T40 engine was also used in the developmental A2D Skyshark, and the XF-84H Thunderscreech. After a number of engine related mishaps the A2J project was abandoned.
