(For other ships with the same name, see HMS Northumberland.) HMS Northumberland was the last of the three Minotaur-class armoured frigates built for the Royal Navy during the 1860s. She had a different armour scheme and heavier armament than her sister ships, and was generally regarded as a half-sister to the other ships of the class. The ship spent her career with the Channel Fleet and occasionally served as a flagship. Northumberland was placed in reserve in 1890 and became a training ship in 1898. She was converted into a coal hulk in 1909 and sold in 1927, although the ship was not scrapped until 1935.
