General Electric F-101 turbofan engines were developed for the Rockwell B-1A Lancer that was cancelled in 1977. GE re-engineered the engines for fighter aircraft under the Derivative Fighter Engine (DFE) program. The new F-101X DFE engine was fitted to the first full-scale development (FSD) F-16A (75-0745) which was known as F-16/101. This aircraft made 58 test flights during 75 hours flight time before the project was cancelled in 1981. The F101X DFE engine was not used in F-16s but was used to develop the GE F-110 engine first used in Block 30 aircraft.
