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.
Od vstopa v uporabo leta 1975, je po skoraj 40 letih še vedno v proizvodnji.
