HMS Tiger was a British battlecruiser constructed during the 1910s, notable for being the most heavily armoured of the Royal Navy's battlecruisers at the outbreak of World War I. Laid down at John Brown and Company in Clydebank on June 6, 1912, she was launched on December 15, 1913, and commissioned on October 3, 1914. Her overall length was 704 feet (214.6 meters), with a beam of 90 feet 6 inches (27.6 meters) and a mean draught of 32 feet 5 inches (9.88 meters). Displacing approximately 28,430 long tons (28,890 tonnes) normally, her mass increased to about 33,260 long tons (33,790 tonnes) at deep load. Her propulsion system comprised two pairs of Brown-Curtis steam turbines housed in separate engine rooms, powered by 39 Babcock & Wilcox boilers operating at 235 psi. These turbines produced up to 104,635 shp (78,026 kW), enabling her to exceed 28 knots (52 km/h). Fuel capacity included 3,800 long tons of fuel oil and 3,340 long tons of coal, providing a range of over 3,300 nautical miles at 24 knots. Armament included eight 13.5-inch (343 mm) guns in four twin turrets, with a maximum range of approximately 23,740 yards (21,710 meters). Her secondary armament comprised twelve 6-inch (152 mm) guns, and anti-aircraft weaponry featured two 3-inch guns. She was also equipped with four submerged 21-inch (530 mm) torpedo tubes. Her armour protection was robust, with a main waterline belt up to 9 inches (229 mm) thick, covering the central citadel and extending to 6 inches (152 mm) over the upper belt. Gun turrets had 9-inch (229 mm) faces, and the main conning tower was protected by 10-inch (254 mm) walls. After the Battle of Jutland, additional armour was added to turret roofs and magazines for added protection. HMS Tiger participated actively in key naval battles, including the Battle of Dogger Bank in 1915 and the Battle of Jutland in 1916, where she was hit multiple times but remained largely intact. Her service was characterized by her speed, firepower, and armour, making her a significant component of the Royal Navy's battlecruiser force. Post-war, she served as a gunnery training ship and provided support during the interwar years before being decommissioned and sold for scrap in 1932 following the constraints of the London Naval Treaty. Her elegant design and combat record have cemented her as one of the most notable warships of her era.
