The Lockheed SR-71 "Blackbird" was an advanced, long range, Mach 3+ strategic reconnaissance aircraft. It was developed from the Lockheed A-12 reconnaissance aircraft in the 1960s by the Lockheed Skunk Works as a black project. Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During reconnaissance missions the SR-71 operated at high speeds and altitudes to allow it to outrace threats; if a surface-to-air missile launch was detected, standard evasive action was simply to accelerate.
