It was originally developed and manufactured by French firm Aérospatiale, which was merged into the multinational Eurocopter company during the 1990s. Since entering production in 1975, the type has been in continuous production for more than 40 years. The intended successor to the Dauphin is the Airbus Helicopters H160, which is yet to enter operational service as of January 2020. The Dauphin 2 shares many similarities with the Aérospatiale SA 360, a commercially unsuccessful single-engine helicopter; however the twin-engine Dauphin 2 did meet with customer demand and has been operated by a wide variety of civil and military operators. Since the type's introduction in the 1970s, several major variations and specialised versions of the Dauphin 2 have been developed and entered production, including the military-oriented Eurocopter Panther, the air-sea rescue HH/MH-65 Dolphin, the Chinese-manufactured Harbin Z-9 and the modernised Eurocopter EC155.
