GE Aerospace has announced a substantial $1.4-billion contract to provide additional T408 turboshaft engines for the US Marine Corps’ Sikorsky CH-53K King Stallion helicopter. This agreement marks a significant expansion of a series of collaborative efforts, following six previous contracts aimed at enhancing the military’s heavy-lift capabilities.
The new multi-year contract includes the delivery of production sets, spare engines, and essential maintenance services, underscoring GE’s commitment to supporting the CH-53K program. The assembly of these engines will take place at GE’s facility in Lynn, Massachusetts, with supplementary manufacturing support from various locations across New Hampshire, Vermont, Kentucky, Ohio, and Florida.
To manufacture the power turbine for the T408 engines, GE will partner with German firm MTU Aero Engines, highlighting the collaborative nature of the project.
The T408 engine is a key component of the CH-53K, having achieved initial operational capability with the Marine Corps in 2022, just four years after the inaugural King Stallion airframe was delivered. Each helicopter is outfitted with three T408 engines, which together generate a remarkable 22,500 horsepower. This is an impressive 57% increase in output compared to the previous T64 engine, greatly enhancing the helicopter’s performance.
The advanced capabilities of the T408 allow the CH-53K to achieve three times the range and payload capacity of its predecessor, the CH-53E Super Stallion. This enhancement significantly improves the helicopter’s ability to transport personnel and equipment, thereby enhancing operational effectiveness for warfighters.
In addition to its power, the T408 is designed for optimized fuel efficiency and maintainability. With 63% fewer components and an 18% increase in efficiency, the engine’s rugged design reduces potential downtime and supports sustained mission readiness.
Scott Snyder, program director of heavy lift engines at GE Aerospace, emphasized the significance of this contract. He stated, “This latest contract is a testament to the T408’s ability to deliver the power, durability, and efficiency the Marine Corps depends on.” He also expressed pride in supporting the CH-53K and its vital role in the missions carried out by Marines and joint forces around the world.
