The S-64 had a six-blade main rotor and was powered by two Pratt & Whitney T73, Pratt & Whitney JFTD12A turboshaft engines. The prototype S-64 first flew on 9 May 1962 and was followed by two further examples for evaluation by the German armed forces. The Germans did not place an order, but the United States Army placed an initial order for six S-64A helicopters (with the designation CH-54 Tarhe, YCH-54A Tarhe).

Following the end of the Korean War, the United States Army sought to procure a successor to the Sikorsky CH-37 Mojave, an early piston-engined heavily lift helicopter; being aware of this need, Sikorsky were keen to fulfil it. The company was already working on the Sikorsky S-64 Skycrane, a civil-orientated heavy lift rotorcraft that was designed specifically for the purpose of carrying large payloads externally; the development of a military-configured derivative was viewed as a natural option ...
