The General Electric CJ610 is a non-afterburning turbojet engine derived from the military J85, and is used on a number of civilian business jets. The model has logged over 16.5 million hours of operation. Civilian versions have powered business jets such as the Learjet 23 and the Hamburger Flugzeugbau HFB-320 Hansa Jet. The engines are also used in the flyable Messerschmitt Me 262 reproductions built by the Me 262 Project in the United States.

A development, the CF700 added a rear-mounted fan mounted directly on the free-running low-pressure turbine.
