English: CIA developed the highly secret A-12 OXCART as the U-2’s successor, intended to meet the nation’s need for a very fast, very high-flying reconnaissance aircraft that could avoid Soviet air defenses. CIA awarded the OXCART contract to Lockheed (builder of the U-2) in 1959. In 1965, after hundreds of hours flown at high personal risk by the elite team of CIA and Lockheed pilots, the A 12 was declared fully operational, attaining the design specifications of a sustained speed of Mach 3.2 at 90,000 feet altitude. The A-12 on display at CIA Headquarters—number eight in production of the 15 A-12s built—was the first of the operational fleet to be certified for Mach 3. No piloted operational jet aircraft has ever flown faster or higher.
