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 was designed to accommodate different gearboxes, or shaft drive for helicopter or turboprop fixed-wing applications. The engine could be operated between 100 degrees upward and 45 degrees downward for STOL or Helicopter applications.[3]
