The LM2500+ engine is the next generation of the industry-leading LM2500

It has all the same high reliability, availability, and high efficiency (lower SFC) as the original LM2500 but with more power. It delivers up to 20 percent more power at a simple-cycle thermal efficiency greater than 39 percent.

The simple modular design of the LM2500+ provides for easy maintenance with features including:

  • A split compressor casing
  • In-place blade and vane replacement
  • In-place hot section maintenance
  • External fuel nozzles

Applications for the LM2500+ include military combatants and amphibious ships. The engine is also available as a generator set.


The 40,500-shp LM2500+ marine gas turbine is based on the design and precedent-setting reliability of GE's popular LM2500.
