Dreadnought battleship of the Italian Royal Navy

Conte di Cavour was the name ship of the three dreadnought battleships built for the Royal Italian Navy (Regia Marina) in the 1910s. Completed in 1915 she served during World War I, although she was little used and saw no combat. The ship supported operations during the Corfu Incident in 1923 and spent much of the rest of the decade in reserve. She was rebuilt between 1933 and 1937 with more powerful guns, additional armor and considerably more speed than before. During World War II, both Conte di Cavour and her sister ship, Italian battleship Giulio Cesare, participated in the Battle of Calabria in July 1940, where the latter was lightly damaged. Conte di Cavour was badly damaged when British torpedo bombers attacked the fleet at Taranto in November 1940. She was deliberately run aground, with most of her hull underwater, and repairs were not completed before the Italian armistice in September 1943. The ship was then captured by the Germans, but they made no effort to finish her repairs. She was damaged in an Allied air raid in early 1945 and capsized a week later. Conte di Cavour was eventually scrapped in 1946.

The Conte di Cavour class was designed to counter the French dreadnoughts which caused them to be slower and more heavily armored than the first Italian dreadnought, Italian battleship Dante Alighieri. The ships were long at the waterline and overall. They had a beam of , and a draft of The Conte di Cavour class ships displaced at normal load, and at deep load. They had a crew of 31 officers and 969 enlisted men. The ships were powered by three sets of Parsons steam turbines, two sets driving the outer propeller shafts and one set the two inner shafts. Steam for the turbines was provided by twenty Blechynden water tube boilers, eight of which burned oil and twelve of which burned both fuel oil and coal. Designed to reach a maximum speed of from , Conte di Cavour failed to reach this goal on her sea trials, despite mildly exceeding the rated power of her turbines, reaching only from The ships carried enough coal and oil to give them a range of at Their secondary armament consisted of eighteen guns mounted in casemates on the sides of the hull in single mounts. For defense against torpedo boats, the ships carried fourteen guns; thirteen of these could be mounted on the turret tops, but they could also 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. The Conte di Cavour class ships had a complete waterline armor belt that had a maximum thickness of amidships, which reduced to towards the stern and towards the bow. They had two armored decks: the main deck was thick on the flat that increased to on the slopes that connected it to the main belt. The second deck was thick. Frontal armor of the gun turrets was in thickness and the sides were thick. The armor protecting their barbettes ranged in thickness from The walls of the forward conning tower were 280 millimeters thick.

Shortly after the end of World War I, the number of 76.2 mm low angle guns was reduced to 13, all mounted on the turret tops, and six new 76.2 mm anti aircraft (AA) guns were installed abreast the aft funnel. In addition two license built 2 pounder AA guns were mounted on the forecastle deck. In 1925–1926 the foremast was replaced by a four legged (tetrapodal) mast, which was moved forward of the funnels, the rangefinders were upgraded, and the ship was equipped to handle a Macchi M.18 seaplane mounted on the amidships turret. Around the same time she was equipped with a fixed aircraft catapult on the port side of the forecastle. Conte di Cavour began an extensive reconstruction in October 1933 at the Cantieri Riuniti dell'Adriatico shipyard in Trieste that lasted until June 1937. A new bow section was grafted over the existing bow, which increased her overall length by to and her beam increased to The ship's draft at deep load increased to Two of the propeller shafts were removed and the existing turbines were replaced by two Belluzzo geared steam turbines rated at
The main guns were bored out to and the amidships turret and the torpedo tubes were removed. All of the existing secondary armament and AA guns were replaced by a dozen 120 mm guns in six twin gun turrets and eight AA guns in twin turrets. In addition the ship was fitted with a dozen Breda light AA guns in six twin gun mounts and twelve Breda M31 anti aircraft machine guns, also in twin mounts. In 1940 the 13.2 mm machine guns were replaced by AA guns in twin mounts. Atop the conning tower there was a fire control director fitted with two large stereo rangefinders, with a base length of .

Conte di Cavour, named after the statesman Count Camillo Benso di Cavour, was laid down at Arsenale di La Spezia, La Spezia, on 10 August 1910, and launched on 10 August 1911. She was completed on 1 April 1915, and served as a flagship in the southern Adriatic Sea during World War I. She saw no action, however, and spent little time at sea. The threat from these underwater weapons to his capital ships was too serious for him to actively deploy the fleet. In 1919 she sailed to North America and visited ports in the United States as well as Halifax, Canada. The ship was mostly inactive in 1921 because of personnel shortages, and was refitted at La Spezia from November to March 1922. Conte di Cavour and Giulio Cesare supported Italian operations on Corfu in 1923 after an Italian general and his staff were murdered at the Greek–Albanian frontier; Italian leader Benito Mussolini, who had been looking for a pretext to seize Corfu, ordered Italian troops to occupy the island. Conte di Cavour bombarded the main town on the island with her 76 mm guns, She escorted King Victor Emmanuel III and his wife aboard Dante Alighieri on a state visit to Spain in 1924, and was placed in reserve upon her return until 1926, when, in April, she conveyed Mussolini on a voyage to Libya. The ship was again placed in reserve from 1927 until 1933, when she began her reconstruction.

Early in World War II, the Conte di Cavour and her sister took part in the Battle of Calabria (also known as the Battle of Punta Stilo) on 9 July 1940. They were part of the 1st Battle Squadron, commanded by Admiral Inigo Campioni, when they engaged major elements of the British Mediterranean Fleet. The British were escorting a convoy from Malta to Alexandria, while the Italians had finished escorting another from Naples to Benghazi, Italian Libya. Vice Admiral Andrew Cunningham, commander of the Mediterranean Fleet, attempted to interpose his ships between the Italians and their base at Taranto. Crews on the fleets spotted each other in the middle of the afternoon and the Italian battleships opened fire at 15:53 at a range of nearly The two leading British battleships, and , replied a minute later. Three minutes after she opened fire, shells from Giulio Cesare began to straddle Warspite which made a small turn and increased speed, to throw off the Italian ship's aim, at 16:00. At the same time, a shell from Warspite struck Giulio Cesare at a distance of about Uncertain how severe the damage was, Campioni ordered his battleships to turn away in the face of superior British numbers and they successfully disengaged. Repairs to Giulio Cesare were completed by the end of August and both ships unsuccessfully attempted to intercept British convoys to Malta in August and September. On the night of 11 November 1940, Conte di Cavour was at anchor in Taranto harbor when she was attacked, along with several other warships, by 21 Fairey Swordfish torpedo bombers from the British aircraft carrier The ship's gunners shot down one Swordfish shortly after the aircraft dropped its torpedo, but it exploded underneath 'B' turret at 23:15, knocking out the main bow pump. Her captain requested tugboats to help ground the ship on a nearby sandbank at 23:27, but Admiral Bruno Brivonesi, commander of the 5th Battleship Division, vetoed the request until it was too late and Conte di Cavour had to use a deeper, , sandbank at 04:45 the following morning. She initially grounded on an even keel, but temporarily took on a 50 degree list before settling to the bottom at 08:00 with an 11.5 degree list. Only her superstructure and gun turrets were above water by this time. Conte di Cavour had the lowest priority for salvage among the three battleships sunk during the attack and little work was done for several months. The first priority was to patch the holes in the hull and then her guns and parts of her superstructure were removed to lighten the ship. False bulwarks were welded to the upper sides of the hull to prevent water from reentering the hull and pumping the water overboard began in May 1941. Some of water were pumped out before Conte di Cavour was refloated on 9 June and entered the ex Austro Hungarian floating dry dock GO 12 on 12 July. The damage was more extensive than originally thought and temporary repairs to enable the ship to reach Trieste for permanent repairs took until 22 December. Her guns were operable by September 1942, but replacing her entire electrical system took longer so the navy took advantage of the delays and incorporated some modifications to reduce the likelihood of flooding based on lessons learned from the attack. Other changes planned were the replacement of her secondary and anti aircraft weapons with a dozen dual purpose guns in twin mounts, twelve , and twenty three 20 mm AA guns. Refloated shortly after the end of the war, Conte di Cavour was scrapped in 1946.
