The YF-12 program was a limited production variant of the A-12. Lockheed convinced the U.S. Air Force that an aircraft based on the A-12 would provide a less costly alternative to the recently canceled North American Aviation XF-108, since much of the design and development work on the YF-12 had already been done and paid for. Thus, in 1960 the ...

The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
[N 1] Development of the F-108 radar and missiles was continued by the USAF and the system was eventually used in the Lockheed YF-12 program.

[3] The original Lockheed 12 version, with Wasp Junior engines, was the Model 12A. [4] Almost every Lockheed 12 built was a 12A or derived from the 12A.
