    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 ...

    Two new world records for flight speed were set by a Lockheed YF-12A jet interceptor on the same day by two different crews. On one flight, the crew broke the 2,000 mph barrier, flying at 2,070.102 miles per hour (Mach 3.27) [1] and shattering the previous speed record of 1,665.8 miles per hour that had been set on July 7, 1962, by a Soviet Ye-166.
