A fourth YF-12 aircraft, the "YF-12C", was actually the second SR-71A (AF Ser. No. 61–7951). This SR-71A was re-designated as a YF-12C and given the fictitious Air Force Serial Number 60-6937 from an A-12 to maintain SR-71 secrecy. The aircraft was loaned to NASA for propulsion testing after the loss of YF-12A (AF Ser. No. 60–6936) in 1971.
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.
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.

Irwin was also a developmental test pilot for the Lockheed YF-12, the Mach 3 fighter-interceptor variant which preceded the SR-71 Blackbird. His first flight of that aircraft was on the day that one of his five children was born. [7] In 1961, a student pilot that Irwin was training crashed the plane they were flying on a training mission.
Similar eyewitness reports were given in the 2002 crash, and an analysis of a video of that crash showed the initiation of a fireball 0.9 seconds after the wing separated. [14] On September 6, 2000, a 1957-built C-130A registered N116TG, operated by T&G Aviation, fighting a fire near Burzet, France, crashed, killing two of the four crewmen on ...
