HMS "Nelson" (pennant number: 28) was the name ship of her class of two battleships built for the Royal Navy in the 1920s. They were the first battleships built to meet the limitations of the Washington Naval Treaty of 1922. Entering service in 1927, the ship spent her peacetime career with the Atlantic and Home Fleets, usually as the fleet flagship. During the early stages of Second World War, she searched for German commerce raiders, missed participating in the Norwegian Campaign after she was badly damaged by a mine in late 1939, and escorted convoys in the Atlantic Ocean.
