About the T700-GE-701:





The General Electric T700 is one of the most successful turboshaft engines ever built. Since the first T700 (the T700-GE-700) entered production in 1978, the engine has accumulated more than 50 million flight operating hours. With an installed inventory of more than 11,000, the General Electric T700 turboshaft and turboprop engines are the most widely used in their class. Also, the General Electric T700 provides great reliability and maintainability. The engine has proven itself in battle, extreme environments, and in commercial service. T700 engines currently power 25 types of civil and military helicopters as well as fixed-wing civil transport aircraft, military transport aircraft, and special-mission aircraft.

T700-GE-701C
The T700-GE-701C is a more powerful version of the T700-GE-700 and a follow on of the T700-GE-701 (these engines are no longer in production). The T700-701C comes with 1,890 shp and features 6 compressor stages and 4 turbine stages (2HP-2LP). The engine powers the U.S. Army's UH-60A/L Black Hawk utility helicopter and AH-64A/D Apache Attack Helicopters. Also, the T700-GE-701C powers U.S. Marine Corps MH-60R Seahawk and MH-60S Seahawk helicopters as well as the U.S. Air Force's HH-60G Pave Hawk.

T700-GE-701D
The newest T700 engine, the T700-GE-701D, provides the latest technologies for field-proven engines. The T700-701D comes with 1,994 shp and features 6 compressor stages and 4 turbine stages (2HP-2LP). The U.S. Army is currently upgrading its fleet of UH-60A/L Black Hawk helicopters to the UH-60M configuration, which includes upgrading the older T700-GE-700 engines to the more powerful and durable T700-GE-701D configuration. This is done with the use of GE upgrade kits. While maintaining a high commonality with the T700-GE-701C, the T700-GE-701D represents an affordable approach to improve the performance and durability of these engines. The T700-701D will power the newest Sikorsky UH-60M Black Hawk utility helicopters and Boeing AH-64E Apache Guardian attack helicopters.
