Jet engines power [[jet aircraft]], [[cruise missile]]s and [[unmanned aerial vehicle]]s. In the form of [[rocket engine]]s they power [[model rocketry]], [[spaceflight]], and military [[missile]]s.

Jet engines have propelled high speed cars, particularly [[drag racer]]s, with the all-time record held by a [[rocket car]]. A turbofan powered car, [[ThrustSSC]], currently holds the [[land speed record]].

Jet engine designs are frequently modified for non-aircraft applications, as [[Gas turbine|industrial gas turbines]] or [[Marine engine|marine powerplants]]. These are used in electrical power generation, for powering water, natural gas, or oil pumps, and providing propulsion for ships and locomotives. Industrial gas turbines can create up to 50,000 shaft horsepower. Many of these engines are derived from older military turbojets such as the Pratt & Whitney J57 and J75 models. There is also a derivative of the P&W JT8D low-bypass turbofan that creates up to 35,000 horsepower (HP)
.

Jet engines are also sometimes developed into, or share certain components such as engine cores, with [[turboshaft]] and [[turboprop]] engines, which are forms of gas turbine engines that are typically used to power [[helicopter]]s and some propeller-driven aircraft.
