Destroyer minesweeper was a designation given by the United States Navy to a series of destroyers that were converted into high-speed ocean-going minesweepers for service during World War II. The hull number for such a ship began "DMS". Forty-two ships were so converted, beginning with the USS Dorsey (DD-117), converted to DMS 1 in late 1940, and ending with the USS Earle (DD-635), converted to DMS-42 in mid 1945. The type is now obsolete, its function having been taken over by purpose-built ships, designated as "minesweeper (high-speed)" with hull numbers beginning MMD.
