ALINDIEN is a French naval acronym designing the admiral in charge of the maritime zone of the Indian Ocean, and of the French forces there. The office has been held by Vice-amiral Antoine Beaussant since 1 August 2013.
ALINDIEN's jurisdiction extends over the maritime zone of the Indian Ocean, dubbed "ZMOI" (zone maritime de l'océan Indien): it comprises the area bounded on its Western part by the Red Sea and Africa, and on its Eastern part by Philippines and Viet Nam. The zone notably comprises such strategic areas as the Persian Gulf, Southern Africa, India, Australia and Singapore.
The zones of La Réunion and of the French Southern and Antarctic Lands operate under a different hierarchy.
In his role as a maritime zone commander, ALINDIEN operates directly under the Chief of the Defence Staff. As a fleet commander, he operates under ALFAN, the Admiral in charge of the Force d'action navale for matters of management, training and preparation of the units permanently stationed in the Indian Ocean. The units are mostly stationed in La Réunion and Djibouti.
ALINDIEN is tasked with the operational control of the naval forces deployed in his area, unless they are detached with their own general staff. This command is exercised from a Durance class command and replenishment oiler (BCR) carrying the entire general staff. Which exact ship is deployed depends on unit turnover, as the ships are relieved every four years; the Marne (A630) has served in this capacity from the summer of 2002. ALINDIEN was the only naval command of the French Navy that is permanently stationed at sea. In autumn 2010, the commanding staff moved ashore to the Abu Dhabi base and the permanently sea-stationed status of the command ended.
ALINDIEN also has duties in defence diplomacy with all neighbouring countries.
