Leonardo da Vinci was a Conte di Cavour classbattleship of the Regia Marina (Italian Royal Navy). She was 170 metres long, small for a battleship. Her twenty boilers and four shafts generated 24MW and gave a top speed of 11 m/s (41 km/h, 21 knots, 25 mph). She was crewed by about 1,000 men.
Leonardo da Vinci was built between 18 July 1910 and 17 May 1914. During World War I, she capsized in Taranto harbour on 2 August 1916 after an explosion blamed by the Italian authorities on Austro-Hungarian sabotage. The explosion killed 249 of her crew.
On 17 September 1919, Leonardo da Vinci was refloated upside down, but repairs were never carried out, and she was sold on 26 March 1923 for scrapping. She officially was stricken on 22 September 1923.
