The General Electric T64 is a free-turbine turboshaft engine that was developed for use on helicopters. GE introduced the engine in 1964. The original engine design included technical innovations such as corrosion resistant and high-temperature coatings.^[1] The engine features a high pressure ratio, yielding low specific fuel consumption.

Later versions of the engine produce from 3,925 to 4,750 shp (2,927 to 3,542 kW).^[2]

The engine is also used in several turboprop fixed-wing applications.
