The CF6-80 series are high-bypass turbofan engines with a thrust range of 48,000 to 75,000&nbsp;lb (214 to 334&nbsp;kN).  Although the HP compressor still has 14 stages, GE did take the opportunity to tidy-up the design, by removing the empty air passage at compressor exit.{{citation needed|date=February 2013}}

The -80 series is divided into four distinct models.

==== CF6-80A3 ====
The CF6-80A3, which has a thrust rating of 48,000 to 50,000&nbsp;lb (214 to 222&nbsp;kN), powered two twinjets, the [[Boeing 767]] and [[Airbus A310]]. The GE-powered 767 entered airline service in [[1982 in aviation|1982]], and the GE powered A310 in early [[1983 in aviation|1983]]. It is rated for [[ETOPS/LROPS|ETOPS]] operations.

For the CF6-80A/A1, the fan diameter remains at 86.4 in (2.19 m), with an airflow of 1435&nbsp;lb/s (651&nbsp;kg/s). Overall pressure ratio is 28.0, with a bypass ratio of 4.66. Static thrust is 48,000&nbsp;lb<sub>f</sub> (214&nbsp;kN). The basic mechanical configuration is the same as the -50 series.

==== CF6-80C2 ====

For the CF6-80C2-A1, the fan diameter is increased to 93 in (2.36 m), with an airflow of 1750&nbsp;lb/s (790&nbsp;kg/s). Overall pressure ratio is 30.4, with a bypass ratio of 5.15. Static thrust is 59,000&nbsp;lb (263&nbsp;kN). An extra stage is added to the LP compressor, and a 5th to the LP turbine.<ref name=GECF6-80C2>{{cite web |url= http://www.geaviation.com/engines/commercial/cf6/cf6-80c2.html |title= CF6-80C2 Engine |publisher= GE Aviation |url-status= bot: unknown |archive-url= https://web.archive.org/web/20081121124612/http://www.geaviation.com/engines/commercial/cf6/cf6-80c2.html |archive-date= 2008-11-21 }}</ref>

The CF6-80C2 is currently certified on fifteen commercial and military [[widebody aircraft]] models including the [[Boeing 747-400]], and [[McDonnell Douglas MD-11]]. The CF6-80C2 is also certified for [[ETOPS|ETOPS-180]] for the [[Airbus A300]], [[Airbus A310]], [[Boeing 767]], [[Boeing KC-767|KC-767A/J]], [[Boeing E-767|E-767J]], [[Kawasaki C-2]], and (as the F138) the [[Lockheed C-5M Super Galaxy]] and [[VC-25A]].

==== F138-GE-100 ====

The F138-GE-100 is a military designation given to the specifically modified version of the CF6-80C2, to produce 50,400–51,600 lbf, with Strict Noise Regulations and Green Emissions, specially and specifically designed for [[Lockheed C-5M Super Galaxy|Lockheed Martin C-5M Super Galaxy]]. This CF6 variant became the new standard for C-5 Galaxies in 2017 after the CF6's predecessor, the GE TF-39, was retired.

====CF6-80E1====

The CF6-80E1 has the highest thrust power of CF6-80 Series family, with the fan tip diameters increased to 96.2 in (2.443m), and an overall pressure ratio of 32.6 and bypass ratio of 5.3.<ref>{{cite web |url= https://www.geaviation.com/sites/default/files/datasheet-CF6-80E1.pdf |title= CF6-80E1 - GE Aviation}}</ref>   The {{convert|68,000|to|72,000|lbf|kN|abbr=on}} variant competes with the [[Rolls-Royce Trent 700]] and the [[Pratt & Whitney PW4000]] to power the [[Airbus A330]].<ref>{{cite web |url= http://www.iasg.co.uk/pdfs/articles/engine_services/CF680E.pdf |title= CF6-80E: Past, present and future |work= Engine Yearbook |date= 2006 |access-date= 2017-03-24 |archive-date= 2018-11-26 |archive-url= https://web.archive.org/web/20181126051531/http://www.iasg.co.uk/pdfs/articles/engine_services/CF680E.pdf |url-status= dead }}</ref>

====Other variants====

The industrial and marine development of the CF6-80C2, the [[General Electric LM6000|LM6000 Series]], has found wide use including fast ferry and high speed cargo ship applications, as well as in power generation. The LM6000 gas turbine family provides power in the 40 to 56 MW range for utility, industrial, and oil & gas applications.<ref>{{cite web|title=LM6000 & SPRINT Aeroderivative Gas Turbine Packages (36 - 64 MW)|url=https://www.ge-distributedpower.com/products/power-generation/35-to-65mw/lm6000-sprint-series|publisher=GE Distributed Power|access-date=2014-06-28|archive-date=2014-06-30|archive-url=https://web.archive.org/web/20140630211009/https://www.ge-distributedpower.com/products/power-generation/35-to-65mw/lm6000-sprint-series|url-status=dead}}</ref>
