The Air Force SR-71 Blackbird Burned Through 8,000 Gallons of Jet Fuel On the Way to Hitting Mach 3 and over 80,000 Feet of Altitude

Automatically curated summary from 19FortyFive.

Journalist Georgia Gilholy reports on the technical management and high fuel consumption of the Lockheed SR-71 Blackbird reconnaissance aircraft. Operating at Mach 3 and altitudes exceeding 80,000 feet, the aircraft consumed up to 8,000 gallons of JP-7 fuel per hour. Former pilot David Peters described balancing center of gravity and inlet doors to minimize aerodynamic drag, while Pratt & Whitney J58 engines transitioned from turbojet to partial ramjet operation. Specialized KC-135Q tankers refueled the jet every two hours, extending its unrefueled 3,000-mile range to 15,000 miles.
