(重定向自OXCART)
The Lockheed A-12 was a reconnaissance aircraft built for the United States Central Intelligence Agency (CIA) by Lockheed's Skunk Works, based on the designs of Clarence "Kelly" Johnson. The aircraft was designated A-12, the 12th in a series of internal design efforts with the A referring to "Archangel", the internal code name of the aircraft. It competed in the CIA's "Oxcart" program against the Convair Kingfish proposal in 1959, and won for a variety of reasons.
