HMS Superb was a Bellerophon-class dreadnought battleship constructed for the Royal Navy, launched on 7 November 1908 and completed in May 1909. She measured 526 feet (160.3 meters) in length, with a beam of 82 feet 6 inches (25.1 meters) and a normal draught of 27 feet (8.2 meters). Displacing approximately 18,596 long tons (18,894 tonnes) at normal load, her design was derived from the revolutionary HMS Dreadnought, featuring slight increases in size, armor, and secondary armament. Her propulsion system consisted of two Parsons direct-drive steam turbines, each driving two shafts, powered by eighteen Yarrow boilers, rated at 23,000 shaft horsepower, enabling her to reach a top speed of over 21 knots during sea trials. Her armament included ten 12-inch (305 mm) Mk X guns in five twin turrets—three along the centerline and two as wing turrets—and sixteen 4-inch (102 mm) secondary guns for anti-torpedo boat defense. She was also fitted with three 18-inch torpedo tubes. Her armor comprised a 10-inch thick Krupp cemented waterline belt and main turret faces of 11 inches, supported by barbettes of 9–10 inches, with decks up to 4 inches thick. HMS Superb's service primarily involved routine patrols and training with the Grand Fleet during World War I, including participation in the Battle of Jutland in May 1916, where she fired 54 shells but sustained no damage. She also engaged in various North Sea operations and fleet cruises. In October 1918, she was transferred to the Mediterranean Fleet as flagship, supporting Allied operations in the Mediterranean and Black Sea after the war's end. Deemed obsolete, she returned to the UK in early 1919, was reduced to reserve, and later served as a gunnery training ship and target vessel. She was ultimately sold for scrap in 1922 and dismantled in 1923, marking the end of her maritime career.
