The General Electric LM2500 industrial and marine turboshaft gas turbine is a derivative of GE Aircraft Engines' CF6-50 aircraft engine. The LM2500 is offered in addition to the LM6000.
It delivers 33,600 shaft horsepower (25.1 MW) with a thermal efficiency of 37 percent. It has been used in various applications such as in U.S. Navy warships (as well as those belongong to other navies), hydrofoils, hovercraft and fast ferries. As of 2004, more than one thousand LM2500 gas turbines have been in service for more than 26 international navies.
The LM2500+ is a Combined Diesel And Gas (CODAG) engine that combines electrical propulsion and a basic LM2500 engine. Queen Mary 2, the world's largest transatlantic cruise liner, uses 2 LM2500+ CODAG units.
The LM2500 is license-built in Japan as the Ishikawajima-Harima LM2500.
