GE LM2500 gas turbines power two newly-commissioned combat ships

Published on: 

GE Marine's LM2500 gas turbines now power two Littoral Combat Ships built by Austal USA that were recently commissioned by the United States Navy: USS Tulsa (LCS 16) and USS Charleston (LCS 18). The powerful LM2500 gas turbines are “Made in America” at GE’s Evendale, Ohio, manufacturing facility, just north of Cincinnati, Ohio.

The commissioning for LCS 16 was held in San Francisco, California, on February 16; LCS 18 was commissioned March 2 in Charleston, South Carolina. According to a U.S. Navy press release, both of these sophisticated surface combatants are high-speed, agile, shallow draft and mission-focused. They are designed for operations in the littoral environment, yet fully capable of open ocean operations.

Sister ship, the future USS Cincinnati (LCS 20), recently completed acceptance trials in the Gulf of Mexico. Since USS Cincinnati is named for the city that is home to GE Marine’s headquarters, there will be a number of local festivities in late March to honor this new ship, including a GE crew ceremony, a tour of GE’s nearby engine manufacturing plant and a Cincinnati Reds baseball game. The ship’s commissioning will occur later this year.


GE will provide LM2500 gas turbines on LCS Independence variants up to LCS 38. All Independence variant LCS are powered by two GE LM2500 gas turbines arranged in a combined diesel and gas turbine configuration with two diesel engines.
