The F119 has a maximum thrust of 35,000 lbf, allowing a sustained supersonic speed of Mach 1.75. The three-stage integrally bladed fan of the F119 is powered by a single-stage low-pressure turbine. The engine’s counterrotating core is fitted with an aerodynamically efficient six-stage high-pressure compressor, which is driven by a single-stage high-pressure turbine, featuring the latest single-crystal superalloy blades and advanced cooling technologies. The F119 has been developed into the F135 engine, which power the F-35 fighter aircraft.
