General Electric F101
The F101 was developed specifically for the Advanced Manned Strategic Aircraft, which became the B-1A. The F101 powered the four development aircraft from 1970 to 1981. The B-1A was officially cancelled in 1977, however as well as the continued flight test program General Electric was awarded a contract to further develop their F101-GE-102 engines. These turbofans eventually powered the B-1B from 1984, entering service in 1985.
The 30,000 lbf (133 kN) of thrust per the B-1B's four F101s have helped the aircraft win 61 world records for speed, payload and range. This range is intercontinental without the requirement for aerial refueling.
