The '''General Electric F101''' is an [[Afterburner|afterburning]] [[turbofan]] [[jet engine]]. It powers the [[Rockwell B-1 Lancer]] [[strategic bomber]] fleet of the [[USAF]]. In full afterburner it produces a thrust of more than {{convert|30000|lb-f|kN|lk=on}}. The F101 was [[GE Aviation|GE]]'s first turbofan with an afterburner.<ref>[http://www.geae.com/engines/military/f101/index.html GE's F101 web page] {{webarchive|url=https://web.archive.org/web/20110211103843/http://www.geae.com/engines/military/f101/index.html |date=2011-02-11 }}</ref>

==Development==
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 the flight test program continued. [[General Electric]] was awarded a contract to further develop the F101-102 engine variant. This turbofan eventually powered the B-1B from 1984, entering service in 1986. The B-1's four F101 engines helped the aircraft win 61 world records for speed, time-to-climb, payload and range.

The [[General Electric F110|GE F110 turbofan]] fighter jet engine is a derivative of the F101, designed using data from the F101-powered variant of the [[F-16 Fighting Falcon]] tested in the early 1980s.<ref>{{cite journal |last1=Dabney |first1=Thomas R. |first2=Michael J. |last2=Hirschberg |title=Engine wars – Competition for U.S. fighter engine production |website=34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit |location=Cleveland, Ohio |date=13–15 July 1998}}</ref><ref>{{cite web |url=http://www.f-16.net/f-16_versions_article11.html |title=F-16/101: Derivative Fighter Engine |website=F-16.net |access-date=24 May 2008}}</ref> The F101 also became the basis for the highly successful [[CFM International CFM56|CFM56]] series of civil turbofans.
