The LM2500+ delivers up to 20% more power compared to the LM2500 at a simple-cycle thermal efficiency greater than 39%. The LM2500+ has same high availability, reliability and higher efficiency (lower SFC) than the LM2500.

As in the case of the LM2500, the LM2500+ simple modular design provides for easy maintenance, featuring a split compressor casing, in-place blade and vane replacement, in-place hot section maintenance and external fuel nozzles. Applications for the LM2500+ include military combatants and amphibious ships. The engine is also available as a generator set.
