Lockheed SR-71A Blackbird

The last of a small family of aircraft built by Lockheed’s famous Skunk Works, the SR-71 is one of the most recognized aircraft ever built. Design of what would become the Blackbird began in 1958 with a request from the CIA for an aircraft to replace the Lockheed U-2. The aircraft the CIA got was a single seat, twin engine, delta-winged design called the A-12. Even though the other versions of the Blackbird were known publicly the existence of the A-12 remained secret until 1982. The type made its first flight from the Groom Lake, Nevada test site in April 1962. Further development resulted in three different 2 seat versions; the YF-12 interceptor, the M-12 which carried the D-21 drone, and the SR-71 strategic reconnaissance aircraft. Slightly larger than the A-12 and with a longer range the first SR-71 flew in December 1964. In total 50 aircraft in the Blackbird Family were built with 30 of them being SR-71s. It is hard to overstate the technological achievement represented by the Blackbird. It holds world speed and altitude records and is the only manned, jet-powered aircraft to routinely exceed Mach 3.
