context_page_description: HMS St Vincent was the lead ship of her class of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. After commissioning in 1910, she spent her whole career assigned to the Home and Grand Fleets, often serving as a flagship. Aside from participating in the Battle of Jutland in May 1916, during which she damaged a German battlecruiser, and the inconclusive Action of 19 August several months later, her service during World War I generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war and was reduced to reserve and used as a training ship. St Vincent was sold for scrap in 1921 and broken up the following year.
context_section_description: The St Vincent class was equipped with ten breech-loading (BL) 12-inch (305 mm) Mk XI guns in five twin-gun turrets, three along the centreline and the remaining two as wing turrets. The secondary, or anti-torpedo boat armament, comprised twenty BL 4-inch (102 mm) Mk VII guns. Two of these guns were each installed on the roofs of the fore and aft centreline turrets and the wing turrets in unshielded mounts, and the other ten were positioned in the superstructure. All guns were in single mounts. The ships were also fitted with three 18-inch (450 mm) torpedo tubes, one on each broadside and the third in the stern.
  The St Vincent-class ships were protected by a waterline 10-inch (254 mm) armoured belt that extended between the end barbettes. Their decks ranged in thickness between 0.75 to 3 inches (19 to 76 mm) with the thickest portions protecting the steering gear in the stern. The main battery turret faces were 11 inches (279 mm) thick, and the turrets were supported by 9-or-10-inch-thick (229 or 254 mm) barbettes.
