The '''''St Vincent''-class battleships''' were a group of three [[dreadnought battleship]]s built for the [[Royal Navy]] in the first decade of the 20th century. The [[sister ship]]s spent their entire careers assigned to the [[Home Fleet|Home]] and [[Grand Fleet]]s. Aside from participating in the [[Battle of Jutland]] in May 1916 and the inconclusive [[Action of 19 August 1916|action of 19 August]] several months later, their service during the [[First World War]] generally consisted of routine patrols and training in the [[North Sea]]. {{HMS|Vanguard|1909|2}} was destroyed in 1917 by a [[Magazine (artillery)|magazine]] explosion with the near total loss of her crew. The remaining pair were obsolete by the end of the war in 1918, and spent their remaining time either in [[Reserve fleet|reserve]] or as [[training ship]]s before being sold for [[ship breaking|scrap]] in the early 1920s.

''Vanguard''{{'}}s wreck was extensively [[Marine salvage|salvaged]] before it was declared a [[war grave]]. Since 2002, it has been designated as a controlled site under the [[Protection of Military Remains Act 1986]] and diving on the wreck is generally forbidden.
