The A-12 Avenger II was an American aircraft program from McDonnell Douglas and General Dynamics intended to be an all-weather, carrier-based stealth bomber[1] replacement for the A-6 Intruder in the United States Navy and Marines. The A-12 project was canceled in 1991 due to high costs.

Design and development

Artists' conceptions and mockups of the craft revealed a flying wing design in the shape of an isosceles triangle, with the cockpit situated near the apex of the triangle. The aircraft was designed to have two General Electric F412-GE-D5F2 turbofans, each producing about 13,000 lbf (58 kN) thrust, and was equipped to carry up to two AIM-120 AMRAAM missiles, two AGM-88 HARMs and a full complement of air-to-ground ordnance, including Mk 82 bombs, or smart bombs, in an internal weapons bay. The A-12 gained the nickname "Flying Dorito".

The aircraft suffered numerous problems throughout its development, especially with the materials, and when the projected cost of each aircraft ballooned to an estimated US$165 million, the project was canceled by then-Secretary of Defense, Dick Cheney, in January 1991.

The cancellation of the project did not adhere to contract requirements, resulted in years of litigation between McDonnell Douglas/General Dynamics and the Department of Defense for breach of contract. On 1 June 2009, the U.S. Court of Appeals for the Federal Circuit ruled that the U.S. Navy had been justified in canceling the contract.[2] Further, the two contractors are now required to repay the U.S. government more than US$1.35 billion, plus interest charges of US$1.45 billion. Boeing, which merged with McDonnell Douglas in 1997, has vowed to appeal the decision, as has General Dynamics.

After the cancellation of the A-12, the Navy elected to buy the F/A-18E/F Super Hornet, which replaces the A-7, the A-6, and the F-14.
