Diego Garcia Base.

The British Indian Ocean Territory (BIOT) or Chagos Islands (formerly the Oil Islands) is an overseas territory of the United Kingdom situated in the Indian Ocean, halfway between Africa and Indonesia. The territory comprises a group of seven atolls comprising more than 60 individual islands, situated some 500 kilometers (310 mi) due south of the Maldives archipelago. The largest island is Diego Garcia (area 44 km squared), the site of a joint military facility of the United Kingdom and the United States. Following the eviction of the native population (Chagossians) in the 1960s, the only inhabitants are US and British military personnel and associated contractors, who collectively number around 4,000 (2004 figures).
