Design and development
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, whilst a 2 stage LP turbine drives the 3 stage fan. The combustor is annular. In 1998, the USAF's Lockheed U-2 fleet was fitted with a modified version of the F118.[1]
