General Electric designed the YJ93 engine to power a planned supersonic interceptor, the F-108, and a bomber, the North American XB-70, at speeds of 2,000 mph and at altitudes about 70,000 feet. The high-pressure variable-stator engine ran on special high-temperature JP-6 fuel and had a thrust-to-weight ratio above 5:1. The Air Force cancelled the F-108 program and only built two XB-70s. The engine was not used in any military or commercial aircraft other than the XB-70.
