HMS Emperor of India was an Iron Duke-class battleship built for the British Royal Navy, representing an incremental evolution over the preceding King George V class. Laid down on 31 May 1912 at the Vickers shipyard and launched on 27 November 1913, she was originally to be named Delhi but was renamed to honor King George V's title as Emperor of India. At commissioning in November 1914, shortly after the outbreak of World War I, she measured 622 feet 9 inches (190 meters) in length overall, with a beam of 90 feet (27 meters) and a draught of approximately 29 feet 6 inches (9 meters). Displacing around 25,000 long tons (25,401 tonnes) at design load and up to 29,560 long tons (30,034 tonnes) fully loaded, she was powered by four Parsons steam turbines supplied by eighteen Babcock & Wilcox boilers, generating 29,000 shp (21,625 kW). This propelled her to a top speed of 21.25 knots (39 km/h), with a cruising radius of 7,800 nautical miles (14,446 km) at 10 knots. Armament comprised ten 13.5-inch (343 mm) Mk V guns in five twin turrets, arranged with superfiring pairs forward and aft, and a central turret amidships. Her secondary armament included twelve 6-inch (152 mm) guns, anti-aircraft weapons, and four submerged 21-inch torpedo tubes. Armor protection featured a main belt up to 12 inches (305 mm) over vital areas, and main turrets with faces 11 inches (279 mm) thick. During her service, HMS Emperor of India joined the 4th Battle Squadron of the Grand Fleet, engaging in patrols, fleet exercises, and supporting operations such as the Battle of Jutland, which she missed due to a late refit. She participated in numerous North Sea sorties and gunnery drills, contributing to fleet actions and strategic demonstrations. After WWI, she was transferred to the Mediterranean Fleet, supporting Allied interventions in the Russian Civil War and observing the Greco-Turkish War. Postwar, she served in the Atlantic Fleet until 1930, when the London Naval Treaty mandated her decommissioning. Ultimately, she was used as a gunnery target in 1932, providing critical data that influenced future British battleship armor design, before being scrapped. Her career exemplifies the rapid evolution of naval technology during the early 20th century and her role in WWI maritime strategy.
