She was a successful but short-lived boat, sinking 13 ships during her career. She was most notorious for her final attack, in which she shelled and sank the small fishing vessel Ebb, and killed a number of its crew with machine-gun fire as they attempted to launch a life raft.

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.
HMS Sportsman was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in 1942, she spent most of the war serving in the Mediterranean Sea. After an initial patrol off Norway, she sank the heavy transport Général Bonaparte in the Mediterranean in 1943 and missed a French oil tanker. She was heavily damaged after a mistaken attack by an Allied bomber, and was sent east after repairs to participate in operations in the Black Sea. After the operation was cancelled, Sportsman patrolled the Aegean Sea, sending several Greek and German ships to the bottom. She sank the German transport SS Petrella in early 1944 despite it being clearly marked as a prisoner-of-war ship, killing 2,670 out of 3,173 Italians aboard. Sportsman sank several more ships, and suffered minor damage when she was detected and sighted while attempting to attack a convoy.
HMS Unrivalled (P45) was a U-class submarine built for the Royal Navy during World War II. The boat has been the only ship of the Royal Navy to ever bear the name Unrivalled. Completed in 1942, the boat spent most of the war in the Mediterranean. She sank a number of small merchant ships and naval auxiliaries, but major success eluded her during the war. Too small and slow for the post-war environment, Unrivalled was scrapped in 1946.

She was launched at the North Sea harbour of Wesermünde in Hanover, Germany in February 1940 as the fishing trawler Malangen and was captured by Norwegian militiamen at the North Norwegian port of Honningsvåg during her maiden fishing journey to the Barents Sea. Having taken part in the defence of Norway in 1940 she spent the rest of the war years patrolling the ocean off Iceland. She was decommissioned in 1946, sold to a civilian fishing company in 1947 and scrapped in 1973.

The vessel escorted convoys between the United States and Europe and between Gibraltar and Bizerte, Tunis and Genoa, Italy. After the war, Wenonah was loaned to the United States Coast and Geodetic Survey for three and a half years before being sold to private interests in 1928. In private ownership, the vessel was renamed at least twice, including Stranger and Blue Water.
