HMS Iron Duke was a dreadnought battleship and the lead vessel of her class, constructed at Portsmouth Dockyard with her keel laid in January 1912. She was launched on October 12, 1912, and commissioned in March 1914. As a key capital ship of the Royal Navy, she measured approximately 622 feet 9 inches (190 meters) in overall length, with a beam of 90 feet (27 meters) and a draught of 29 feet 6 inches (9 meters). Displacing about 25,000 long tons (25,401 tons) at design load, her full load displacement increased to approximately 29,560 long tons (30,034 tons). Her propulsion system comprised four Parsons steam turbines powered by eighteen Babcock & Wilcox boilers, producing 29,000 shaft horsepower and allowing her to reach a top speed of 21.25 knots (39 km/h). She had a cruising radius of 7,800 nautical miles at 10 knots. Armament included a main battery of ten 13.5-inch (343 mm) guns mounted in five twin turrets, with two superfiring pairs forward and aft and a central amidships turret. Her secondary armament consisted of twelve 6-inch (152 mm) guns, complemented by anti-aircraft weaponry—initially two 3-inch (76 mm) guns and later upgrades—and four submerged 21-inch (533 mm) torpedo tubes. Her armor protection included a main belt up to 12 inches (305 mm) thick over vital areas, a deck 2.5 inches (64 mm) thick, and turret faces of 11 inches (279 mm). HMS Iron Duke served as the flagship of the Grand Fleet during World War I, notably participating in the Battle of Jutland, where she inflicted significant damage on the German battleship SMS König. Post-Jutland, she underwent armor reinforcement and served in various roles, including flagship of the Mediterranean Fleet and later as a training ship. Following the 1930 London Naval Treaty, she was converted into a gunnery training vessel, with much of her armament and armor removed. During World War II, she was stationed at Scapa Flow, serving as a harbor defense ship; she sustained damage from German air attacks and was run aground to prevent sinking. She remained in service in a limited capacity until the end of the war and was ultimately sold for scrap in 1948. HMS Iron Duke’s legacy includes her significant role in early 20th-century naval history and her presence during pivotal naval battles.
