The first USS Abbot (DD-184) was a Wickes-class destroyer in the service of the United States Navy until traded to Britain at the beginning of World War II. She served in the Royal Navy as HMS Charlestown (I-21), a Town class destroyer.
Based at Norfolk, Virginia, the destroyer operated along the east coast and in the Gulf of Mexico and the Caribbean, especially in Cuban waters. The destroyer was placed out of commission at the Philadelphia Navy Yard on 5 July 1922.
After being laid up for almost two decades, Abbot was recommissioned on 17 June 1940 and patrolled along the east coast until going out of commission once more at Halifax, in Nova Scotia, on 23 September 1940 to be transferred to the UK under terms of the agreement by which the United States exchanged 50 overage destroyers for bases on British colonial territory in the Atlantic. Abbot was struck from the Navy list on 8 January 1941.
See USS Abbot for other ships of the same name.
Charlestown was damaged in a collision with the steamer Florizell off Harwich, England in December 1944. Due to her age, it was decided not to repair her, and the destroyer was placed in reserve at Grangemouth, Firth of Forth. Charlestown was decommissioned on 15 January 1945 and was eventually scrapped.
