General Electric F101

The General Electric F101 is an afterburning turbofan jet engine that powers the Rockwell B-1 Lancer strategic bomber fleet of the United States Air Force. In full afterburner it produces a thrust of more than 30,000 pounds-force, and it was the first General Electric turbofan fitted with an afterburner. It was developed for the Advanced Manned Strategic Aircraft that became the B-1A, powered the four development aircraft from 1970 to 1981, and after the B-1A was cancelled in 1977 the F101-102 variant was developed further to power the B-1B from 1984. The B-1 and its four F101 engines won 61 world records for speed, time to climb, payload and range. The F110 fighter engine is a derivative of the F101, and the F101 also became the basis of the CFM56 family of civil turbofans.
