HMS Centurion was a King George V-class dreadnought battleship constructed for the Royal Navy in the early 1910s. She measured approximately 597 feet 9 inches (182.2 meters) in length, with a beam of 89 feet 1 inch (27.2 meters) and a draught of 28 feet 8 inches (8.7 meters). Displacing around 25,420 long tons (25,830 metric tons) at normal load, she was powered by two Parsons steam turbines, each driving two shafts, fueled by 18 Yarrow boilers. During sea trials in February 1913, she achieved a maximum speed of 22.9 knots, slightly exceeding her intended 21 knots, and had an operational range of 6,310 nautical miles at 10 knots. Her armament comprised ten 13.5-inch (343 mm) Mark V guns in five twin turrets, all on the centerline, and sixteen 4-inch (102 mm) secondary guns. She also featured three submerged 21-inch (533 mm) torpedo tubes. Her armor included a 12-inch waterline belt, with main gun turrets protected by 11-inch faces and supported by 10-inch barbettes. The ship’s fire-control was initially upgraded before August 1914, and additional deck armor was added post-Jutland to improve her survivability. HMS Centurion's service history included participation in the Battle of Jutland in May 1916, where she engaged German forces but was lightly involved. She also took part in routine patrols and training during WWI. After the war, she was transferred to the Mediterranean Fleet, serving briefly during the Russian Civil War and later as flagship of the Reserve Fleet. From 1926, she was converted into a radio-controlled target ship for aerial bombing trials, with her turrets removed and her superstructure modified for her new role. During WWII, her armament was lightened, and she was converted into a blockship and decoy vessel, outfitted with dummy turrets to mislead Axis forces. She was involved in convoy escort operations in 1942 and was ultimately scuttled on 9 June 1944 during the Normandy invasion to serve as a breakwater for Mulberry harbours. HMS Centurion’s varied career highlights her adaptation from a front-line battleship to a versatile auxiliary vessel, reflecting the evolving naval strategies of the first half of the 20th century.
