The leader in its class, the T700 engine family powers military rotorcraft throughout the world. Initiated as a new program in 1967 for the U.S. Army as a result of lessons learned from helicopter operations in Vietnam, the T700 development was designed to power a next-generation utility helicopter: the Sikorsky UH-60 BLACKHAWK.
Ruggedness, safety and the ability to operate reliably under adverse environmental conditions while requiring minimal maintenance is the foundation of the T700 military engine family design. Certified in 1976, the T700-GE-700 entered full scale production in 1978 and became the engine of choice the UH-60 and AH-64 Apache, providing 25 percent lower sfc and 50 percent greater power to weight ratio than its turboshaft predecessors.
The T700 engine was FAA certified in 1976 as the CT7 engine family and entered commercial service on the Bell 214ST. The CT7 engine continues to support commercial rotorcraft throughout the world.
The T700 engines represent a quantum leap in reliability and maintainability over other engines in their class. Since its introduction, the T700 engine family has been proven in battle, in extreme environments, and in demanding passenger revenue service, amassing more than 60 million engine flight hours, powering over 20 types of rotary and fixed-wing aircraft for close to 125+ customers in 50+ countries.
GE is committed to continue growth and innovation of the T700 military engine family with focus on key and enduring requirements: survivability, maintainability, and low life cycle costs. Through the infusion of advanced technology and innovation from military and commercial development, today's T700 models provides twice the power and three times the durability of its baseline T700-GE-700 baseline configuration.
