HMS Comet was a C-class destroyer built for the Royal Navy in the early 1930s. She saw service in the Home and Mediterranean Fleets and the ship spent six months during the Spanish Civil War in late 1936 in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. Comet transferred to the Royal Canadian Navy (RCN) in 1938 and renamed HMCS Restigouche. During World War II, she served as a convoy escort in the battle of the Atlantic, on anti-submarine patrols during the invasion of Normandy, and was employed as a troop transport after VE Day for returning Canadian servicemen, before being decommissioned in late 1945. Restigouche was sold for scrap in 1946.
