HMS Trenchant was a modified Admiralty R-class destroyer which served with the Royal Navy. The vessel was the first of the modified design. Launched in 1916, the ship operated with the Grand Fleet during the First World War. The vessel was involved in escorting convoys and attacking German submarines. After the war, Trenchant was attacked by Republican forces during the Irish War of Independence but suffered little damage. The vessel was retired and sold to be broken up on 15 November 1928. The subsequent S-class are sometimes called Modified Trenchant class.
