The LM2500 marine gas turbine is a simple-cycle, two-shaft, high-performance engine. Derived from GE's CF6-6 aircraft engines, the LM2500 consists of a gas generator, a power turbine, attached fuel and lube oil pumps, a fuel control and speed governing system, associated inlet and exhaust sections, lube and scavenge systems as well as controls and devices for starting and monitoring engine operation.
The LM2500 is GE's most widely-applied gas turbine, used by 33 navies worldwide. Possible applications for the LM2500 include patrol boats, corvettes, frigates, destroyers, cruisers, cargo/auxiliary ships and aircraft carriers. The LM2500 is also available as a military generator set.
