General Electric F110

The General Electric F110 was an axial-flow compressor engine with afterburning turbofan. The F110 was developed in 1985 by General Electric from the F101 engine for the US Air Force and the US navy to power the F-16C Fighting Falcon, F-15K Strike Eagle, and the F-14B Super Tomcat. The GE F110 was developed using the same basic design of the F101; the innovation was that it had a different fan and afterburner packages to improve engine performance.

The GE F110 provided approximately 4,000 lbf (17.8 kN) more thrust than the F100-PW-200 as it required more air, which led to the increase in the area of the engine intake. The F-16C/D Block 30/32s were the first to be built with this larger intake and a common engine bay, able to accept both engines.
