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 is a family of commercial engines derived from the T700 turboshaft engine developed to power the US Army's UH-60 helicopter in the late 1970s. This commercial engine leverages the T700's reliability, operation under adverse environmental conditions and low maintainability. The first CT7 engines were introduced into service in 1984 on the Saab 340 and CASA/IPTN CN235. The CT7 engine family power range is between 1,700-shp and 2,800-shp powering both rotary-wing and fixed-wing aircraft.

The CT7-2 is commercial engine powering the Bell 214ST (B214ST) and S-70C helicopters in roles ranging from executive and medical transport to search and rescue, fire fighting and offshore oil rig support. The engine compressor includes six stages and is rated at 1,625-shp of power at sea level takeoff. The CT7-2E1 is a further variant selected to power the AgustaWestland AW189 helicopter. The CT7-2F1 variant has been selected to power the Bell 525 helicopter.
