The US Army was left as the only military establishment on the base after both RAF establishments (at Kindley Field and Darrell's Island) were withdrawn at the end of the war (followed by the closure of most of the Royal Naval Dockyard and withdrawal of the last regular British Army unit in the 1950s), although the RAF (and the Royal Navy Fleet Air Arm) has continued to use its end of the field, converted to a Civil Aviation Terminal by the Civil Aviation department of the Bermuda Government (headed by wartime RAF commander Wing Commander Mo Ware), as a staging post for trans-Atlantic flights.
