HMS Splendid was a third-batch S-class submarine built for the Royal Navy during World War II. She was laid down on 7 March 1941 and launched on 19 January 1942. After an initial patrol through the Bay of Biscay to Gibraltar, Splendid conducted two patrols in the Mediterranean Sea; one was abandoned after technical problems and on the other she sank two Italian ships. On her next patrol, the submarine attacked two Italian convoys, sinking an Italian destroyer in the second attack. Based in Algiers, the boat operated north of Sicily, sinking six Italian ships, including two tankers and two heavy merchant ships. Splendid was detected by a German destroyer on 21 April 1943 while patrolling off Naples, Italy; the submarine was attacked with depth charges by the destroyer and forced to surface, after which she was scuttled and her surviving crew members taken prisoner. She was the most successful British submarine by tonnage sunk between November 1942 and May 1943.
