The sinking of the Rainbow Warrior, codenamed Opération Satanique, was an operation by the "action" branch of the French foreign intelligence services, the Direction générale de la sécurité extérieure (DGSE), carried out on 10 July 1985. During the operation, two operatives sank the flagship of the Greenpeace fleet, the Rainbow Warrior in the port of Auckland, New Zealand on its way to a protest against a planned French nuclear test in Moruroa.
