The United States Naval Station Whites Island was a United States Navy (USN) facility located on White's Island in Hamilton Harbour, in the British Colony of Bermuda, 640 miles off the coast of North Carolina. It was established during the First World War (or the Great War, as it was originally known in Britain) by the US Navy for use by anti-submarine vessels transiting on their way from the United States to the European theatre of operations. The US bases were closed in January, 1919, following the ceasation of hostilities.
