HMS Rodney (pennant number 29) was one of two Nelson-class battleships built for the Royal Navy in the mid-1920s. She was named after Admiral Lord Rodney. The Nelsons were unique in British battleship construction, being the only ships to carry a main armament of 16 inch (406 mm) guns, and the only ones to carry all the main armament forward of the superstructure. As her superstructure was located aft of midships.
Admiral Graf Spee, scuttled after the Battle of the River Plate in December 1939 when the Germans were duped by British Intelligence into believing an overwhelming force awaited her if she emerged from the Uruguayan port of Montevideo, where she had taken refuge. Her Captain, who shot himself, was a humanitarian well respected by those captured during her commerce raiding cruise.
