The '''General Electric LM2500''' is an industrial and marine [[gas turbine]] produced by [[GE Aerospace|GE Aviation]]. The LM2500 is a derivative of the [[General Electric CF6#CF6-6|General Electric CF6-6]] aircraft engine.

As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power [[warship]]s.<ref>{{cite press release|title=GE Marine to Supply IHI with LM2500 Gas Turbines to Power Japan's 15DDG AEGIS Destroyer|date=6 May 2004|publisher=GE Aviation|url=http://www.geae.com/aboutgeae/presscenter/marine/marine_20040506.html|url-status=dead|archive-url=https://web.archive.org/web/20061017064552/http://www.geae.com/aboutgeae/presscenter/marine/marine_20040506.html|archive-date=17 October 2006}}</ref> Other uses include [[hydrofoil]]s, [[hovercraft]] and [[High-speed craft|fast ferries]].

In 2012, GE developed an [[FPSO]] version to serve the oil and gas industry's demand for a lighter, more compact version to generate electricity and drive compressors to send natural gas through pipelines.<ref>{{cite web|url=http://www.worldoil.com/April-2012-From-aircraft-to-blowout-preventer-GEs-global-technology-cross-pollinates.html|title=From aircraft to blowout preventer, GE's global technology cross-pollinates|publisher=World Oil Online|date=10 September 2012|access-date=10 September 2012|archive-url=https://web.archive.org/web/20140314104439/http://www.worldoil.com/April-2012-From-aircraft-to-blowout-preventer-GEs-global-technology-cross-pollinates.html|archive-date=14 March 2014|url-status=live}}</ref>

The module consists of two General Electric LM2500 gas turbine engines and a Westinghouse gear reduction unit.]]

The LM2500 was first used on the US Navy {{Ship|GTS|Admiral W. M. Callaghan}} in 1969, after the original [[Pratt & Whitney FT4]] gas turbines experienced many technical problems.<ref name=":0">{{Cite web|title=GTS Admiral W.M. Callaghan {{!}} MARAD|url=https://www.maritime.dot.gov/multimedia/gts-admiral-wm-callaghan|access-date=2020-08-11|website=www.maritime.dot.gov|archive-date=1 October 2020|archive-url=https://web.archive.org/web/20201001080544/https://maritime.dot.gov/content/gts-admiral-wm-callaghan|url-status=live}}</ref> Later, they were used in US Navy warships in the {{sclass|Spruance|destroyer|4}} of destroyers and the related {{sclass|Kidd|destroyer|4}}, which were constructed from 1970. In this configuration it was rated to {{convert|21500|SHP|abbr=on}}.  This configuration was subsequently used into the 1980s in the {{sclass|Oliver Hazard Perry|frigate}}s, and {{sclass|Ticonderoga|cruiser}}s. It was also used by one of People's Republic of China's [[Type 052 destroyer|Type 052 Luhu Class Missile Destroyer (Harbin 112)]] acquired before the embargo.

The LM2500 was uprated to {{convert|26500|SHP|abbr=on}} for the {{sclass|Arleigh Burke|destroyer|1}}s, which were initiated in the 1980s and started to see service in the early 1990s, and the T-AOE-6 class of fast combat tanker.

In 2001 the LM2500 (20 MW) was installed in a sound-proof capsule in the South African Navy {{sclass|Valour|frigate|4}} (Meko A-200 SAN) frigates as part of a CODAG propulsion system with two MTU 16V 1163 TB93 Propulsion Diesels.

The current generation was uprated in the late 1990s to over {{convert|30000|SHP|abbr=on}}.

The LM2500 is typically installed within a metal enclosure that provides sound and thermal isolation from adjacent machinery spaces. This enclosure is comparable in size to a standard {{convert|40|ft|m|adj=on}} [[Containerization|intermodal shipping container]], although the engine’s dimensions slightly exceed standard container measurements. Air intake ducting is often designed to facilitate straightforward removal of the LM2500 from the vessel.

The LM2500+ is an evolution of the LM2500, delivering up to {{convert|40200|shp|kW|abbr=on}} or 28.6 MW of electric energy when combined with an [[electrical generator]]. Two of such turbo-generators have been installed in the superstructure near the [[funnel (ship)|funnel]] of ''[[Queen Mary 2]]'', the world's largest transatlantic ocean liner, for additional electric energy for the liner to reach higher sea speeds.<!-- no, this is not CODAG -->  [[Celebrity Cruises]] uses two LM2500+ engines in their {{sclass|Millennium|cruise ship|1}}s in a [[COGAS|COGES]] cycle.

The LM2500 is license-built in India by [[Hindustan Aeronautics Limited]];<ref>[https://www.gemarinesolutions.com/markets/military GE Marine Solutions Military page]{{Dead link|date=December 2022 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> in Italy by [[Avio Aero]];{{citation needed|date=May 2019}} and in Japan by [[IHI Corporation]].<ref>{{Cite web |title=GE to Provide IHI with LM2500 and LM500 Gas Turbines for Japan's New 24DDH Destroyer; IHI/GE Celebrate Milestone {{!}} GE Aviation |url=https://www.geaviation.com/press-release/marine-industrial-engines/ge-provide-ihi-lm2500-and-lm500-gas-turbines-japans-new |access-date=2022-07-29 |website=www.geaviation.com}}</ref> (Subsequent to the February 2024 reporting of an IHI company [[whistleblower]];<ref>{{cite news |title=Japan's IHI rigged data for over 4,000 engines at least since 2003 |url=https://english.kyodonews.net/news/2024/04/1b35909379dd-japans-ihi-rigged-data-for-over-4000-engines-at-least-since-2003.html |access-date=29 April 2024 |work=english.kyodonews.net |publisher=Kyodo News}}</ref> On April 24, 2024, IHI announced that investigation was underway by Japan's [[Ministry of Land, Infrastructure, Transport and Tourism]] of its subsidiary, IHI Power Systems Co., which had falsified its engine data since 2003, impacting over 4,000 engines globally.<ref>{{cite news |title=IHI Subsidiary Falsifies Data on Engine Performances of Ships and Trains |url=https://japannews.yomiuri.co.jp/business/companies/20240424-182175/ |access-date=29 April 2024 |work=The Japan News}}</ref>)

The LM2500/LM2500+ can often be found as turbine part of [[combined diesel and gas|CODAG]], [[combined diesel or gas|CODOG]], [[Combined diesel-electric and gas|CODLAG]] propulsion systems or in pairs as powerplants for [[COGAG]] systems.{{cn|date=April 2024}}

==Specification==
The basic LM2500 has a single shaft gas generator derived from the CF6, comprising a 16 stage compressor driven by a two stage air-cooled HP turbine. The combustion chamber is annular. Shaft power is generated by a 6-stage power turbine mounted in the gas generator exhaust stream.  Additional power is obtained from the LM2500+ by the addition of a zero stage to the compressor, making 17 stages in all.
