The General Electric F118-GE-100 is a non-afterburning turbofan engine produced by GE Aviation and is derived from the General Electric F110 afterburning turbofan.

The F118 is a non-afterburning derivative of the F110 specially developed for the B-2 Spirit stealth bomber. A single-stage HP turbine drives the 9 stage HP compressor, while a 2-stage LP turbine drives the 3 stage fan. The combustion is annular. In 1998, the USAF's Lockheed U-2S fleet was fitted with a modified version of the F118.

The engines have an exhaust temperature control system to minimise thermal signature.
