HMS Queen Elizabeth was the flagship of her class of five dreadnought battleships built for the Royal Navy in the early 1910s. She measured 639 feet 9 inches (195 meters) in overall length, with a beam of 90 feet 7 inches (27.6 meters) and a deep draught of 33 feet (10.1 meters). Her standard displacement was approximately 32,590 long tons (33,113 metric tons), increasing to 33,260 long tons (33,794 metric tons) at deep load. The vessel was powered by two sets of Parsons steam turbines, each driving two shafts, utilizing steam from 24 Babcock & Wilcox boilers. These turbines were rated at 75,000 shaft horsepower (56,000 kW), enabling her to reach a maximum speed of 25 knots (46.3 km/h; 28.8 mph). She had a range of 5,000 nautical miles (9,260 km; 5,754 mi) at a cruising speed of 12 knots (22.2 km/h; 13.8 mph), and her crew numbered around 1,262 officers and ratings in 1920. Her armament included eight 15-inch (381 mm) Mk I guns in four twin turrets, arranged in superfiring pairs fore and aft of the superstructure, designated 'A', 'B', 'X', and 'Y'. The secondary armament comprised twelve 6-inch (152 mm) Mk XII guns, mostly mounted in casemates along the broadside amidships, with two additional guns on the forecastle deck. Anti-aircraft defenses included two quick-firing 3-inch (76 mm) guns, while she was also equipped with four submerged 21-inch (533 mm) torpedo tubes. Fire control was provided by two directors with 15-foot (4.6 m) rangefinders, one above the conning tower protected by an armored hood, and another in the spotting top above the foremast. Her armor featured a waterline belt of 13 inches (330 mm) of Krupp cemented armor (KC) over vital areas, with gun turrets protected by 11 to 13 inches (279 to 330 mm) of KC. The main conning tower was also heavily armored with 13 inches (330 mm). Throughout her service, she underwent numerous modifications, including enlargements, updated fire control systems, and armament changes, notably replacing her 6-inch guns with 4-inch guns during the 1937–1941 rebuild. Her deck armor was increased, and facilities for aircraft operations were added. Constructed at Portsmouth Dockyard, she was laid down in October 1912, launched in October 1913, and completed in January 1915. HMS Queen Elizabeth served prominently during World War I, notably participating in the Gallipoli Campaign, where she engaged Ottoman defenses, and in the Battle of Jutland, although she was not present at the latter. She also played a pivotal role in the German armistice signing aboard her in November 1918. In the interwar years, she served as a flagship in various fleets, participated in fleet reviews, and supported military interventions such as the Abyssinia Crisis. During World War II, she saw action in the Mediterranean, supporting operations at Crete, and was damaged by Italian mines in Alexandria harbor. Post-repairs, she participated in the Pacific theater, supporting operations in Southeast Asia until her decommissioning and scrapping in 1948. HMS Queen Elizabeth remains a significant example of early 20th-century dreadnought design and naval history.
