Description: The CF6 engine was designed to power commercial airplanes. Its military version, F103 military designation, has been provided to power large military aircraft like KC-10, B-767 AWACS, Air Force One, E-4B and the YAL-1A aircraft. In the early 2000s CF6 family engines have been selected to power KC-767 and A330 tanker/transport aircraft.

The CF6-80C2 emerged from CF-6080A engine featuring higher thrust and more efficient slightly larger fan. This engine has thrust ratings from 52,500-lb to 63,500-lb and entered commercial service in 1985.

The F138-GE-100 is a CF6 variant derived from CF6-80C2 turbofan engine and intended to power the US Air Force re-engined C-5/C-5M Galaxy strategic transport aircraft. F138 engine focuses on fuel efficiency which, according to the US Air Force, may translate into fuel savings equaling re-engining program cots by 2029. Beginning in 2007 112 C-5A/Bs owned by the US Air Force should be powered by the General Electric F138 engine by 2020.

Under the C-5M Super Galaxy modernization program, General Electric would deliver more than 450 CF6/F138 engines to the US Air Force to power 111 C-5Ms beginning in 2010 through 2040 when the aircraft type is expected to enter retirement.
