The SR-71 Blackbird was the world's fastest air-breathing aircraft, capable of cruising at Mach 3.2 at 85,000 feet with a top speed of over 2,200 mph. Built from 1964 to 1999, it was designed to fly reconnaissance missions at extreme speeds and altitudes that could not be matched by Soviet defenses. Its unique design, which included a titanium alloy structure and special anti-heat paint, allowed it to withstand the high temperatures encountered during supersonic flight. With its incredible speed and stealthy design, the Blackbird conducted numerous missions over hostile territory without ever being shot down.
