Italian Battleship Leonardo Da Vinci

The third of the Conte di Cavour-class battleships, Leonardo da Vinci was launched on14 October 1911 and commissioned into the Italian Regia Marina on 17 May 1914. She saw no action during the First World War and was sunk by internal explosion on 2 August 1916. Italy blamed the loss on Austro-Hungarian saboteurs although the loss may have been accidental.
