The A-12 Oxcart was a reconnaissance aircraft developed by the Lockheed Corporation in the 1960s. Designed by Kelly Johnson and his team at the Skunk Works, it was built for high-altitude, high-speed surveillance missions during the Cold War. The aircraft could fly at speeds over Mach 3 and reach altitudes of 90,000 feet, making it difficult to detect and intercept. The A-12 was the precursor to the more famous SR-71 Blackbird. It featured a sleek, aerodynamic design and advanced materials to withstand extreme temperatures. Although only 15 units were built, the A-12 played a crucial role in gathering intelligence and shaping aerial reconnaissance technology.
