I just had to look it up ... I couldn't believe that the British had a 16" gun battleship: http://en.wikipedia.org/wiki/HMS_Nelson_(28)

HMS Nelson (pennant number 28) was one of two Nelson-classbattleships built for the Royal Navy between the two World Wars. She was named in honour of Horatio Nelson, 1st Viscount Nelson the victor at the Battle of Trafalgar. 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.
These were a result of the limitations of the Washington Naval Treaty. Commissioned in 1930, Nelson served extensively in the Atlantic, Mediterranean, and Indian oceans during World War II. She was decommissioned soon after the end of the war and scrapped in 1949.
