Description: The T700 engine was designed for the US Army's UH-60A Black Hawk helicopter as a result of lessons learned in Vietnam. The key requirements of this engine were reliability, operation under adverse environmental conditions and low maintainability.

The CT7-8 engine is the newest commercial derivative of T700 engine family. It has been designed jointly with FiatAvio from Italy to power the S-92 multirole helicopter. The CT7-8A engine features an advanced, higher-flow compressor designed with new three-dimensional aerodynamic technology, a full authority digital electronic control (FADEC) system, and hot-section and turbine components proven in millions of flight hours on the CT7-9 engine.

Following Canada selection of Sikorsky's H-92 Cyclone for its $3 billion maritime helicopter project. The General Electric's CT7-8A turboshaft engines was selected to power Canada's H-92 twin-engine helicopters. These engines will be assembled, inspected, tested, repaired and overhauled locally.
