The General Electric LM2500 is a gas turbine for ships and industrial plants, produced by GE Aviation (now GE Aerospace) as a derivative of the CF6-6 aircraft engine. It was first used on the US Navy vessel GTS Admiral W. M. Callaghan in December 1969, in comparative trials against the Pratt and Whitney FT4. Those trials showed about 20 percent lower fuel consumption with comparable reliability, so the LM2500 won the contract for the Spruance-class destroyers, with the first units ordered in 1970. Its rating grew from 21,500 shaft horsepower in that first configuration to over 30,000 shp for the current generation, and the LM2500+ evolution delivers up to 40,200 shp. By 2004 the US Navy and at least 29 other navies had used more than one thousand LM2500 and LM2500+ turbines in warships, and the engine also powers hydrofoils, hovercraft, fast ferries and the electrical generators of the liner Queen Mary 2. A lighter version for the oil and gas industry followed in 2012, and the engine is built under licence in India, Italy and Japan.
