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.

The "Electra Junior" name did not catch on in the way that the original Electra's name had. Most users simply referred to the aircraft by its model number, as the Lockheed 12. [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.
Lockheed YF-94 (S/N 48-373). This was the second aircraft built (from TF-80C) On 16 April 1949, the first YF-94 prototype performed its maiden flight. [6] To accelerate development, these early test aircraft were converted from existing T-33s; they maintained roughly 75% commonality in terms of components with those used in the earlier F-80 and T-33As.
