Ascension Island is an isolated volcanic island, 7°56′ south of the Equator in the South Atlantic Ocean. It is about 960 miles (1,540 km) from the coast of Africa and 1,400 miles (2,300 km) from the coast of South America. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 800 miles (1,300 km) to the southeast. The territory also includes the sparsely populated Tristan da Cunha archipelago, 2,000 miles (3,200 km) to the south, about halfway to the Antarctic Circle.

Ascension Island was possibly discovered by the Portuguese seafarer João da Nova in 1501, before being named Ascension by Afonso de Albuquerque in 1503 on Ascension Day. Ascension Island was garrisoned by the British Admiralty from 22 October 1815 to 1922 and was an important refuelling stop for ships and commercial airliners in the days of international air travel by flying boats. During World War II, it was an important naval and air station, especially providing antisubmarine warfare bases in the Battle of the Atlantic.
