HMS Centurion was the second of four King George V-class dreadnought battleships built for the Royal Navy in the early 1910s. She spent the bulk of her career assigned to the Home and Grand Fleets. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, and the Battle of Jutland in May 1916, her service during the First World War generally consisted of routine patrols and training in the North Sea.

The King George V-class battleships were a group of four dreadnought battleships built for the Royal Navy (RN) in the early 1910s that were sometimes termed super-dreadnoughts. The sister ships spent most of their careers assigned to the 2nd Battle Squadron of the Home and Grand Fleets, sometimes serving as flagships. In October 1914, Audacious struck a mine and sank. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, the Battle of Jutland in May 1916 and the inconclusive action of 19 August, the surviving ships' service during the First World War generally consisted of routine patrols and training in the North Sea.
