The machine is propelled by two turboshafts, has a four-blade main and a four-blade tail rotor as well as a retractable landing gear. The prototype completed its first flight on March 13, 1977. The development of the machine began with Sikorsky in the middle of the 1970s. Target group were companies, which looked for a medium business helicopter, as well as the oil drilling industry. Sikorsky's development experiences from the UH-60 Black Hawk served as the basis for the S-74 (later renamed S-76 in honor of the US Bicentennial). The prototype, which was able to transport 2 pilots and 12 passengers, received first two Allison 250C30 turboshafts with 478 kW each. The S-76A was the main production variant.
