The General Electric YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent and divergent exhaust nozzle, designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. Its maximum sea-level thrust was 28,800 pounds-force. It began as the J79-X275, an enlarged J79 for a target speed of Mach 2.75, evolved into the X279 when Mach 3 cruise became a requirement, and ran on a special high-temperature JP-6 fuel. The six engines of the XB-70 allowed about Mach 3 at 70,000 feet. The first engine went on test in September 1958, and the XF-108 was cancelled outright while the B-70 became a research project only.
