The T901 Turboshaft Engine
Developed to provide the future of propulsion for the U.S. Army's Black Hawk and Apache helicopters
Built on insights from four decades of proven performance on the T700 engine, the newly designed T901 (formerly GE3000) will deliver more power, fuel efficiency, and durability for the Army's Improved Turbine Engine Program (ITEP).
By incorporating the latest in 3D aerodynamics, Ceramic Matrix Composites and additive manufacturing, the T901 can deliver exceptional performance with a single-spool architecture that also reduces complexity and weight. That makes it easy and cost-effective to maintain in the field—and that means more mission capability for U.S. soldiers.
Optimized Power for Black Hawk and Apache helicopters
Designed to succeed the legendary T700 engine, the T901 leverages decades of operational experience to ensure Army warfighters have the best engine possible. It integrates advanced technologies—including those developed under the Future Affordable Turbine Engine (FATE) program—to provide 25% better fuel economy, 35% lower acquisition and maintenance costs, 20% longer life and as much as 65% more power to weight compared to the T700.
- 50% more power at SL/ISA
- 25% reduced fuel consumption
- Capitalizes on more than 40 years of integration experience with Black Hawk and Apache
- Single spool core architecture to deliver reliability, maintainability and performance
- 20% longer life
- Advanced technology and manufacturing. including: CMC, Additive manufacturing and 3D aerodynamics

Increased attack capabilities
The T901 delivers added power and reduced fuel consumption while doubling ammunition payload, enhancing maneuverability and time on station.
Enhanced security mission support
Designed to support complex requirements in a hot and high environment, the T901 will increase operational range by 25% over its predecessor.
Improved air assault power
Even in austere environments, the T901 will increase payload 50% and will mass combat power 25% faster than its predecessor.
Expanded MEDEVAC abilities
The T901 will help wounded troops receive medical assistance faster with a higher OGE hover ceiling and extended operation range.
Advanced technology programs
In addition to the T901’s broad T700 baseline of experience, the US Army and GE Aviation are collaborating on six cooperative agreements to advance technology developments for the Army’s next generation turboshaft engine designs.

Advanced Affordable Turbine Engine program
GE has been selected for the AATE program, which is designed to validate technologies needed to achieve the aggressive performance goals of the Army’s Improved Turbine Engine Program (ITEP). GE has completed testing on its second T901 engine in 2014, and additional AATE technology development is ongoing.
Future Affordable Engine Technology
The FATE program is designed to develop engine technologies for 5,000 – 10,000 shp size engines. FATE program goals include an 80% increase in power-to- weight ratio, 35% reduction in specific fuel consumption, 20% longer design life and 45% lower production and maintenance costs. GE Aviation continues to support Joint Multi-Role/Future Vertical Lift (JMR/FVL) through multiple programs and is investing heavily to ensure advanced technology is ready when required.
Advanced Variable Speed Power Turbine
GE is collaborating with the U.S. Army and NASA to research and develop turbines that can meet the range and life requirement for current and future rotorcraft. The AVSPOT program aims to develop an engine that allows the rotor to be slowed for high speed rotorcraft performance improvements.
Autonomous Sustainment Technologies for Rotorcraft Operations
GE is collaborating with the United States Army Applied Technology Directorate (AATD), which launched the ASTRO program to demonstrate a broad spectrum of technologies that more effectively design and maintain current and future vertical lift fleets.
Capabilities Based Operations & Sustainment Technologies – Aviation
Cost-A is designed to demonstrate an integrated set of high value diagnostics, prognostics and system health management technologies that reduce scheduled inspections and preventive maintenance while enhancing safety.
Rotorcraft Advanced Engine Integrated Control System
The U.S. Army has selected GE Aviation to perform conceptual design and trade analysis on the Rotorcraft Advanced Engine Integrated Controls System (RAEICS) program. The 24-month project will develop innovative, high performance systems for Future Vertical Lift (FVL) platforms.
Advanced manufacturing & materials
GE is revolutionizing production capabilities to deliver faster, lighter and more cost-effective solutions for today’s warfighters
Also known as 3D printing, additive manufacturing is the process of creating parts directly from a computerized drawing using fine metal powder and an electron beam or laser. This allows engineers to design complex, intricate parts, make prototypes more quickly and efficiently and eliminate substantial weight while maintaining the part’s strength and integrity.
GE is incorporating additive manufacturing in its AATE, FATE and ITEP programs.
Ceramic Matrix Composites
Offering superior durability and thermal capabilities, Ceramic Matrix Composite (CMC) components are one-third the density and one-third the weight of current metal alloys. This allows engines to run hotter and reduces weight throughout the engine, leading to improved fuel efficiency and environmental performance.
The T901 incorporates CMC components. GE is running hot section CMC components in other military engines currently on test.
Inlet Particle Separator for hot and harsh conditions
Environmental contamination, such as the dust and sand typical of desert combat zones, can cause an engine’s performance to deteriorate over time. GE has invested in an enhanced sand testing facility to determine maximum turboshaft engine sand separation efficiency.
GE is partnering with the Army to design and test an improved Inlet Particle Separator for its T901 engine.
