HMS Repulse was a Renown-class battlecruiser constructed for the Royal Navy during World War I. She was originally designed as an improved Revenge-class battleship, but construction was suspended at the war’s outbreak, then resumed under the supervision of Admiral Lord Fisher, who sought a fast, heavily armed vessel. The ship was laid down on 25 January 1915 by John Brown in Clydebank, Scotland, and launched on 8 January 1916, completing in August 1916. Her overall length was approximately 794 feet 2.5 inches (242.1 meters), with a beam of about 89 feet 11.5 inches (27.4 meters), and a maximum draught of 29 feet 9 inches (9.1 meters). Displacing around 26,854 long tons (27,285 metric tons) at normal load, Repulse was powered by Brown-Curtis steam turbines producing over 118,000 shaft horsepower, achieving speeds up to 31.73 knots during trials. The vessel's main armament consisted of six 15-inch (381 mm) Mk I guns in three twin turrets, supplemented by 17 4-inch (102 mm) secondary guns and two submerged 21-inch (533 mm) torpedo tubes. Her armor included a 6-inch waterline belt amidships, with turret armor ranging from 7 to 9 inches and deck armor initially from 0.75 to 1.5 inches, later reinforced after the Battle of Jutland with additional high-tensile steel. Repulse also featured a shallow anti-torpedo bulge for protection against underwater damage and was the first capital ship fitted with a flying-off platform for aircraft. In her service, Repulse participated in the Second Battle of Heligoland Bight in 1917, her only engagement during WWI, where she scored a hit on the German cruiser SMS Königsberg. She served as the flagship of the 1st Battlecruiser Squadron and was involved in operations protecting Allied shipping and engaging German forces. Between the wars, she was reconstructed twice, notably in the 1920s and 1930s, with improvements to armor and aircraft facilities. During WWII, Repulse initially patrolled in the North Sea and Atlantic, escorting convoys and searching for German raiders. In December 1941, she was part of Force Z, along with the battleship Prince of Wales, tasked with deterring Japanese landings in Malaya. On 10 December 1941, she was sunk by a coordinated Japanese air attack near Singapore, with her wreck resting at approximately 183 feet (56 meters) underwater. The sinking marked a significant loss for the Royal Navy and underscored the evolving threat posed by air power to capital ships. A memorial at Teluk Cempedak commemorates HMS Repulse and Prince of Wales.
