context_page_description: The Conte di Cavour–class battleships were a group of three dreadnoughts built for the Royal Italian Navy in the 1910s. The ships were completed during World War I, but none saw action before the end of hostilities. Leonardo da Vinci was sunk by a magazine explosion in 1916 and sold for scrap in 1923. The two surviving ships, Conte di Cavour and Giulio Cesare, supported operations during the Corfu Incident in 1923. They were extensively reconstructed between 1933 and 1937 with more powerful guns, additional armor and considerably more speed than before.
  Both ships participated in the Battle of Calabria in July 1940, when Giulio Cesare was lightly damaged. They were both present when British torpedo bombers attacked the fleet at Taranto in November 1940, and Conte di Cavour was torpedoed. She was grounded with most of her hull underwater and her repairs were not completed before the Italian surrender in September 1943. Conte di Cavour was scrapped in 1946. Giulio Cesare escorted several convoys, and participated in the Battle of Cape Spartivento in late 1940 and the First Battle of Sirte in late 1941.
context_section_description: The Conte di Cavour–class ships were designed by Rear Admiral Engineer Edoardo Masdea, Chief Constructor of the Regia Marina, and were ordered in response to French plans to build the Courbet-class battleships. They were intended to be superior to the Courbets and to remedy Dante Alighieri's perceived flaws of weak protection and armament. As upgrading a warship's protection and armament on a similar displacement typically requires a loss in speed, the ships were not designed to reach the 23 knots (43 km/h; 26 mph) of their predecessor. They were still given a 1.5 to 2 knots (2.8 to 3.7 km/h; 1.7 to 2.3 mph) advantage over the 20-to-21-knot (37 to 39 km/h; 23 to 24 mph) standard of most foreign dreadnoughts. Foreign dreadnoughts were being designed with 340-millimeter (13.5 in) guns, but the Regia Marina was forced to use 305-millimeter (12 in) guns in the Conte di Cavours because Italy lacked the ability to build larger guns. An additional gun, making a total of 13, was added to offset this deficiency.
  Taking advantage of the lengthy building times of these ships, other countries were able to build dreadnoughts that were superior in protection and armament, with the exception of the French. Construction was delayed by late deliveries of the 305-millimeter guns and armor plates as well as shortages of labor. The Italo-Turkish War of 1911–1912 diverted workers at the shipyards for repairs and maintenance of the ships participating in the war. The Italians imported the raw nickel steel for their armor from America and Britain and processed it into their equivalent of Krupp cemented armor, called Terni cemented, but there were problems with this process and suitable plates took longer to produce than planned.
