Historic Aircraft - The Avenger That Couldn’t Avenge

By Norman Polmar, Author, Ships and Aircraft of the U.S. Fleet

The A-12 would be a large aircraft, with wingspan limited by the requirement to fit two A-12s on adjacent catapults on a carrier flight deck. In addition, two A-12s with folded wings had to be accommodated on a deck-edge elevator.

Prospects for the A-12 were promising: The Navy planned to buy 620 aircraft and the Marine Corps another 238, with the first to enter service about 1995. At one point, the Air Force was reported to be considering a 400-plane buy; however, as with that service’s procurement of the Navy-developed F4H/F-4 Phantom and A-7 Corsair, it probably would have taken “outside” direction for the Air Force to acquire the aircraft.

As the A-12 was being developed, Vice Admiral Richard Dunleavy, the Deputy Chief of Naval Operations (Air), on 5 March 1990, noted, “I like what I see and [it] will be a good airplane.” 2 The cancellation of the planned A-6F variant of the Intruder seemed to further ensure the success of the A-12 effort. Also, the two other carrier aircraft then in production, the F-14 Tomcat and F/A-18 Hornet, were not suitable for the “medium” attack role, i.e., as an Intruder replacement. Indeed, a headline in Jane’s Defence Weekly in 1990 declared, “USN’s A-12 Avenger: in good shape for survival.” 3

The shootdown came a short time later.

The aircraft—yet to fly—was not meeting specifications: It was overweight, and manufacturing was proving more difficult than anticipated. After seven years of research and development, and an expenditure of some $5 billion, the ATA/A-12 Avenger program was halted. Aviation historian James Stevenson’s excellent account of the program tells a tale of changes in leadership, objectives, and funding “that were bound to devastate the program.” 4 But overarching was the byzantine procurement “system” Congress had imposed on the Pentagon and the Defense Department’s own self-imposed bureaucracy. At the time, the estimated unit cost for production aircraft was $96 million, and the program was over budget and some 18 months behind schedule.

With the end of the program, the government wanted the aircraft contractors to return some of the funding. McDonnell Douglas and General Dynamics disputed the claim in federal court. The legal issues dragged on for more than a decade.

In the event, the A-12 was not built and there would be no successor to the highly regarded A-6 Intruder. The ubiquitous F/A-18 Hornet—in later variants—would become the U.S. Navy’s only carrier-based attack aircraft.
