Aerospatiale developed the Dauphin as a replacement for their older Alouette III helicopters in both civil and military service, with the prototype flying in 1972. By the time that the original single-engine version ( SA 360 ) had entered production, a twin-engine version had already flown which was to form the basis for the SA 365.

US Coast Guard HH-65A Dolphin

In the early 1980s, the United States Coast Guard selected the SA 366G Dauphin (with the H-65 Dolphin DoD designation) to fill a need for a new air-sea rescue helicopter. In order to comply with US law, however, the majority of the helicopters' value had to be produced locally, and this resulted in the substitution of Avco Lycoming engines in place of the original Turboméca units, amongst other engineering changes.
