GE Aerospace has received orders to supply eight LM2500 marine gas turbine engines for the US Navy’s next two Flight III Arleigh Burke-class guided-missile destroyers, the future USS Ray Mabus (DDG 147) and USS Robert R. Ingram (DDG 149).
Announced on November 2, 2026, the orders cover four engines for each destroyer. The LM2500 gas turbines will provide propulsion power for the two ships, which are part of the US Navy’s ongoing Arleigh Burke-class destroyer program.
As of April 2026, 75 Arleigh Burke-class destroyers were in active service, all powered by GE Aerospace’s LM2500 engines as their primary propulsion system. With the latest orders, GE Aerospace continues to supply propulsion systems for the entire class, with demand for the destroyer program projected through 2056.
The US Navy has taken delivery of more than 700 LM2500 gas turbines, which are used to power frigates, destroyers and other surface combatants. The engine first entered naval service in 1969 and has since evolved through several variants, including the LM2500+, LM2500+G4 and related configurations.
GE Aerospace said improvements to the engine's hardware design have drawn on operational experience from both naval and commercial applications. The company reports a 99 percent reliability rate for its marine gas turbines, based on more than 55 years of operational experience.
The LM2500 is used by multiple navies worldwide, with thousands of engines in service across naval fleets.
