 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 .
