HMS Splendid was a third-batch S-class submarine constructed for the Royal Navy during World War II, representing a notable asset in Allied maritime operations in the Mediterranean. Laid down on 7 March 1941 at Chatham Dockyard and launched on 19 January 1942, she measured 217 feet (66.1 meters) in length, with a beam of 23 feet 9 inches (7.2 meters) and a draught of 14 feet 8 inches (4.5 meters). Displacing 865 long tons (879 tons) on the surface and 990 long tons (1,010 tons) submerged, the vessel was powered by two 950-horsepower diesel engines for surface travel and electric motors for submerged operations. She could reach speeds of 15 knots on the surface and 10 knots submerged, with a range of 6,000 nautical miles at 10 knots when on the surface, and a submerged range of 120 nautical miles at 3 knots. The armament of HMS Splendid included six 21-inch (533 mm) torpedo tubes in the bow, one external stern tube, and six reload torpedoes, totaling thirteen torpedoes. She also carried a 3-inch (76 mm) deck gun, with uncertain inclusion of a 20-millimeter Oerlikon AA gun. The submarine was fitted with ASDIC and early-warning radar systems to enhance detection capabilities. Her crew comprised 48 officers and ratings, and she was designed to operate at depths up to 300 feet (91 meters). During her service, HMS Splendid conducted multiple patrols in the Mediterranean, operating primarily off Toulon, Naples, and Sicily. She achieved significant success, sinking eight Axis ships totaling 25,234 GRT, including merchant vessels, a German U-boat, and an Italian destroyer, Velite. Notably, she sank the Italian schooner San Paolo, the merchant Favorita, and the armed trawler Violette, among others. Her most distinguished period was between November 1942 and May 1943, during which she was the most successful British submarine by tonnage sunk. Her service ended on 21 April 1943 when she was detected off Naples by the German destroyer Hermes, which attacked her with depth charges. Forced to surface due to leaks caused by the attack, HMS Splendid was fired upon and scuttled by her crew to prevent capture. Despite her sinking, her commander, Lieutenant Ian McGeoch, survived and made successful escape attempts, ultimately reaching Switzerland. HMS Splendid's operational history underscores her significance as a highly effective wartime submarine in the Mediterranean theater.
