St. David's Island is one of the main islands of the British Overseas Territory of Bermuda. It is located in the far north of the territory, one of the two similarly sized islands that make up the majority of St. George's Parish.
The island was originally 503 acres (2.04 square kilometres) in size. During World War II, in 1942 it was enlarged by reclamation, and by absorbing Long Bird Island and Cooper's Island, to 650 acres (2.63 square kilometres), in order to allow room for a United States military base (originally the US Army's Fort Bell/Kindley Field, operated jointly during the war with the British Royal Air Force). This was later renamed as Kindley Air Force Base and USNAS Bermuda, which occupied more than half the island's land under a 99-year lease.
