Shrowded in secrecy at the time of development in 1.983, the A-12 reportedly gained the nickname “Flying Dorito”.
Development of the A-12 was hampered by problems.
The project was cancelled in January 1.991 by then-Secretary of Defense Dick Cheney when the estimated price of each plane allegedly hit $165 million.
The cancellation was said to be a breach of contract, resulting in years of legal wrangling.
After the cancellation of the A-12 Avenger II the Navy purchased the F/A-18E/F Super Hornet.
While there was never a full scale prototype, an earlier (1.976 – 1.984) classified General Dynamics technology demonstrator called Model 100 (funded under the have key program) may have paved the way for the cancelled A-12.
The A-12 has also been linked to a secret plane called Sneaky Pete, which may or may not be the Model 100, or a development thereof.
We were able to locate one A-12 mock-up thanks to those savvy online explorers at Virtual Globetrotting.
