Turkish Engine Industries (TEI) won a U.S. Navy maintenance contract for LM2500 power turbine modules with a ceiling value of $67.5 million, marking the company's second major contract with the American military in consecutive years.
The contract, signed in the second quarter of 2025, follows TEI's previous $45.6 million agreement with the U.S. Navy in 2024 for gas generator depot-level maintenance services for LM2500 engines.
With 40 years of experience in aviation engines, TEI continues to expand its role as a strategic maintenance center for marine gas turbines used by both Turkish and international naval forces.
TEI conducts maintenance and repair operations for LM2500 gas turbine engines used by both the Turkish Navy and the U.S. Navy, which operates the world's largest LM2500 fleet, at its advanced technology-equipped facilities in Eskisehir.
The company has achieved superior technology and skilled human resources capabilities to provide maintenance and repair services for LM2500 engines used by numerous countries' inventories.
TEI has established itself as a globally preferred strategic maintenance center, ensuring the sustainability of propulsion systems for frigates, corvettes, destroyers, and amphibious-type vessels.
In March 2024, TEI announced it had taken the first step toward becoming a global maintenance, repair, and overhaul center for LM2500 engines through an agreement signed with engine manufacturer General Electric (GE) Marine in 2023.
According to the TEI's announcement, TEI will conduct depot-level maintenance and overhaul services for LM2500 engines used by the U.S. Navy at TEI facilities during the 14 months lasting until October 2026.
The LM2500, derived from TF39 and CF6-6 aviation engines, is one of the world's most preferred marine gas turbines with numerous global users.
The LM2500 marine gas turbine engine delivers 33,600 shaft horsepower or shp (25,060 kilowatts or kW) and operates at 3,600 revolutions per minute (rpm) power turbine speed. Key technical features include:
LM2500's Performance Characteristics
LM2500's System Components
The LM2500 engine family works effectively across various naval vessel types, including patrol boats, corvettes, frigates, destroyers, cruisers, cargo/auxiliary ships, and aircraft carriers. The engine is also available as a military generator set configuration.
GE Aerospace's 1,140 marine gas turbines operate worldwide on a total of 513 naval vessels, providing reliable power to 39 different international navies.
