WASHINGTON, D.C. - Senior Army aviation leaders expect the Improved Turbine Engine Program (ITEP) to reach full qualification by 2028, signaling a recovery for the project following years of delays and a narrow escape from cancellation. The timeline for service entry of the GE Aerospace T901-GE-900 engine, designed to repower UH-60 Black Hawk and AH-64 Apache helicopters, remains dependent on consistent funding and the completion of roughly 6,500 hours of testing.
The program's future was recently secured after Congress pushed back against an Army plan to sunset the initiative, instead providing $175 million in fiscal 2026 funding and $63 million in reconciliation money. Brig. Gen. David Phillips, deputy of Program Acquisition Executive for Maneuver Air, stated that this support allows the service to continue altitude and flight testing initiated last year. The engine is intended to replace heavier components, providing a 50 percent increase in horsepower and a 25 percent improvement in fuel efficiency.
To achieve full qualification, the ITEP must undergo 1,500 hours of ground testing and nearly 5,000 hours of full engine qualification testing. While the Army has not disclosed the total hours completed to date, officials confirmed that flight testing began last May with a Black Hawk and has since expanded to approximately 30 hours of various flight conditions.
