The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39 , the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners.

GE Aerospace's CF6 engine family powers nearly 70 percent of the world's widebody aircraft. The CF6 is the leading engine of choice for new and conversion widebody freighters due to its proven durability, reliability, and performance.

The CF6-80C2 is a ubiquitous engine, with more than 3,200 units in operation and powering five widebody aircraft families. The General Electric (GE) CF6- 80C2 series is one of the most popular widebody engines in operation. The first engines were delivered in 1986 and there are still outstanding orders for 747-400s with CF6-80C2 engines.

Feb 2, 2017 · It all started with the development of GE Aviation’s CF6 engine more than 45 years ago. The CF6 engine entered service in 1971, with the CF6-6, a 40,000-pound thrust engine that powered American Airlines’ and United Airlines’ DC-10 Series 10 aircraft.

Mar 29, 2023 · After an incredible 49 years and six months of service, General Electric (GE) officially retired its CF6-6 engine in June 2021. The remaining engine variants, the CF6-80C2, CF6-50, CF6-80A and...

Jul 1, 2021 · As of June 3, all CF6-6 engines, the original CF6 engine variant, are officially retired. These are some of GE Aviation’s oldest operating commercial jet engines, one of which had reached more than 49 years and 6 months of service before its final flight.

Mar 23, 2025 · The General Electric CF6 family of high-bypass turbofan engines stands out as one of the most successful widebody engines ever developed. Even though it was first developed in the late 1960s and early 1970s, it remains in production for freighter aircraft.

The CF6, a two-shaft turbofan engine from GE Aerospace, is designed for medium- and long-haul widebody aircraft produced by Airbus and Boeing. MTU has been a key risk- and revenue-sharing partner in the development and production of the CF6 since 1971.

The CF6 engine family has a power range of up to 313 KN (72,000 lb) of thrust, and powers other aircraft including the Boeing 747 and 767, McDonnell Douglas MD-11, and Airbus Industrie A300, A310 and A330.

The CF6 engine, developed by GE Aviation, represents the pinnacle of turbofan engine technology in commercial aerospace. Its innovative modular design allows for easy maintenance and component interchangeability, while delivering exceptional performance through advanced aerodynamics and high efficiency.
