The Colossus-class battleships were 1st generation dreadnought battleships of the Royal Navy built at Palmers and Scott shipyard in 1909-1911. They were also the last with 12-inch gun for the RN, but with a different configuration of turrets mounted amidship en echelon. They spent time at the Home and Grand Fleets, often as flagships.
Furthermore, they took part in the Battle of Jutland in May 1916, and the action of 19 August later, to break the relative boredom of their routine patrols and training in the North Sea. They were deemed obsolete by 1918, reduced to reserve in 1919 with Hercules being sold for scrap in 1921, Colossus lingering as a training ship until hulked in 1923, sold 1928.
