U.S. Army Selects GE Aviation’s T901-GE-900 Turboshaft Engine for Improved Turbine Engine Program (ITEP)

The U.S. Army has selected GE Aviation’s T901-GE-900 turboshaft engine for the Engineering and Manufacturing Development (EMD) phase of the Improved Turbine Engine Program (ITEP).

The ITEP, formerly called the Advanced Affordable Turbine Engine (AATE) program, is the U.S. Army’s endeavor to re-engine its fleet of Boeing AH-64 Apache attack helicopters and Sikorsky UH-60 Black Hawk utility helicopters. Apaches and Black Hawks are currently powered by General Electric T700 engine.

The other contender for the project was ATEC HPW3000 engine designated as T900. ATEC is a 50/50 joint venture created in 2007 between Honeywell Aerospace and Pratt & Whitney Military Engines.

“We are honored to be chosen by the Army to continue powering their Black Hawks and Apaches for decades to come,” said Tony Mathis, president and CEO of GE Aviation’s military business. “We’ve invested in the resources and infrastructure to execute immediately, and our team is ready to get to work on delivering the improved capabilities of the T901 to the Warfighter.”

Statement from GE on the ITEP Selection:

GE has powered Black Hawks and Apaches for the past four decades with its T700 engine, racking up more than 100 million flight hours of combat-proven experience. Through continuous upgrades and technology advancements, GE has doubled the power of derivative engines in the T700 family over its lifetime and reduced its cost to the government by 50 percent.

GE carried over the benefits of the T700 engine’s single-spool core architecture, ensuring that the T901 engine is ready to continue delivering combat readiness to the Warfighter over the next four decades. The T901’s single-spool core design is the key to its low cost, growth, reliability, maintainability and reduced life-cycle costs.

The full modularity of the T901’s single-spool core provides the Army with superior fix-forward maintainability. Combat units can swap out modular parts of the engine in the field and travel with fewer full-sized spare engines, simplifying logistical footprints and supply lines. The fully modular design also offers superior growth potential at a lower cost through incremental improvements to engine modules, a significant advantage to meet the Army’s FVL requirements. The U.S. Army is also expecting the ITEP engine to meet Future Attack Reconnaissance Aircraft (FARA) requirements for Future Vertical Lift (FVL).

GE has invested $9 billion in maturing technologies applicable to the T901 and more than $300 million to develop and test turboshaft-specific technologies. Additionally, GE has invested more than $10 billion in their supply chain over the past decade, including eight new facilities, ten plant expansions and one-and-a-half million square feet of new, advanced manufacturing space in the U.S. This robust, first-in-class supply chain stands ready to deliver T901 engines to the Army.

GE’s T901 turboshaft design, manufacturing, assembly and testing will be supported by the following site locations: Lynn, Mass.; Auburn, Ala.; Huntsville, Ala.; Norwich, Conn.; Newark, Del.; Loves Park, Ill.; Jacksonville, Fla.; Madisonville, Ky.; Grand Rapids, Mich.; Muskegon, Mich.; Hooksett, N.H.; Asheville, N.C.; West Chester, Evendale, and Dayton, Ohio; and Rutland, Vt.
