The main battery of the Conte di Cavour class consisted of thirteen 305-millimeter Model 1909 guns, in five gun turrets, with a twin-gun turret superfiring over a triple-gun turret in fore and aft pairs, and a third triple turret amidships.Hore, p. 175 Their secondary armament consisted of eighteen guns mounted in casemates on the sides of the hull. For defense against torpedo boats, the ships carried fourteen guns; thirteen of these could be mounted on the turret tops, but they could be positioned in 30 different locations, including some on the forecastle and upper decks. They were also fitted with three submerged torpedo tubes, one on each broadside and the third in the stern.Giorgerini, pp. 268, 277–278
