The Lockheed YF-12 is an American Mach 3+ capable, high-altitude interceptor prototype, developed and manufactured by American aerospace company Lockheed Corporation.. The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).
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.
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.
Robert L. "Silver Fox" Stephens (December 1, 1921 – May 21, 1984) was a United States Air Force test pilot who set several speed and altitude records while testing the Lockheed YF-12 and SR-71. Biography

Lockheed's initial concept was a particularly large aircraft called CL-2016, nicknamed "battlecruiser" for its size, that resembled its SR-71/YF-12 with large delta wings and engines mounted in nacelles spaced away from the fuselage and would have had similarly high operating speed and altitude as a missile platform (or "missileer" per Lockheed).
