GE Aerospace

GE Aerospace, headquartered in Evendale, Ohio, supplies aeroderivative marine gas turbines through its Marine & Industrial business. Its best-known marine engine is the LM2500. GE says it is used by 39 navies, with more than 1,500 installations and over 16 million operating hours. The engine powers patrol boats, corvettes, frigates, destroyers, cruisers, auxiliary ships and aircraft carriers, typically in CODAG, CODLAG and COGAG arrangements, and is also offered as a generator set.

The marine range spans roughly 4.5 MW to 53 MW. The LM500 (about 4.6 MW) is aimed at fast patrol boats and corvettes. The LM2500 (about 25 MW) and the fourth-generation LM2500+G4 (about 35 MW, 41% more power than the base LM2500) cover most frigate and destroyer programmes. The LM6000 (about 46–53 MW) serves amphibious ships, floating production units and LNG carriers, either as a mechanical drive or as a generator set for electric propulsion.

LM2500-family turbines are also built and packaged under licence by partners, including Avio Aero in Italy and IHI in Japan. GE Aerospace provides field and depot-level repair and overhaul services for its marine fleet worldwide.
