Engine Overview
The -701C is a more powerful version of the -700 and follow on -701, both no longer in production. The -701C powers the latest UH-60L Black Hawk variants and AH-64A/D Apaches.
The U.S. Army's program to upgrade its fleet of UH-60A and -60L Black Hawk helicopters to the UH-60M configuration includes upgrading the aircraft's T700-GE-700 engines, using GE kits, to the more powerful and durable T700-GE-701D configuration.
The T700-701D upgrade is an example of GE's continuing commitment to improve its engines through the infusion of new technologies and materials developed for its other military and commercial engines. T700-701D engines are to be delivered later this year for flight testing.
The T700/CT7 engine family provides greater reliability and maintainability compared with other engines in its class. The T700/CT7 family has proven itself in battle, extreme environments, and in commercial revenue service, amassing more than 35 million engine flight hours.
With an installed base of more than 11,000 engines, GE's T700/CT7 turboshaft and turboprop engines are the most widely used engines in their class. The engines currently power 25 types of civil and military helicopters as well as regional airliners, military transports, and multipurpose aircraft.
