Vittorio Veneto was the second member of the Littorio class of battleships that served in the Italian Regia Marina (Royal Navy) during World War II. Her keel was laid down in October 1934, she was launched in July 1937, and she was readied for service with the Italian fleet by August 1940. She was named after the Italian victory at Vittorio Veneto during World War I, and she had three sister ships: Littorio, Roma, and Impero, though only Littorio and Roma were completed during the war. She was armed with a main battery of nine 381-millimeter (15.0 in) guns in three triple turrets, and could steam at a speed of 30 knots (56 km/h; 35 mph).

Vittorio Veneto saw extensive service during the war and participated in the Battle of Cape Spartivento in November 1940 and the Battle of Cape Matapan in March 1941. She was damaged by torpedoes several times, including in the engagement off Cape Matapan and by the British submarine HMS Urge in December 1941, though she escaped undamaged during the British raid on Taranto in November 1940. She spent 1941 and early 1942 attempting to attack British convoys to Malta, but crippling fuel shortages in the Italian fleet curtailed activity thereafter. Vittorio Veneto was among the Italian ships that were surrendered to the Allies in September 1943 after Italy withdrew from the war, and she spent the following three years under British control in Egypt. After the war, she was allocated as a war prize to Britain and subsequently broken up for scrap.

Description

Line-drawing of the Littorio class

Vittorio Veneto was 237.76 meters (780.1 ft) long overall and had a beam of 32.82 m (107.7 ft) and a draft of 9.6 m (31 ft). She was designed with a standard displacement of 40,724 long tons (41,377 t), a violation of the 35,000-long-ton (36,000 t) restriction of the Washington Naval Treaty; at full combat loading, she displaced 45,236 long tons (45,962 t). The ship was powered by four Belluzo geared steam turbines rated at 128,000 shaft horsepower (95,000 kW). Steam was provided by eight oil-fired Yarrow boilers. The engines provided a top speed of 30 knots (56 km/h; 35 mph) and a range of 3,920 mi (6,310 km; 3,410 nmi) at 20 kn (37 km/h; 23 mph). Vittorio Veneto had a crew of 1,830 to 1,950 over the course of her career.[2][3]

Vittorio Veneto's main armament consisted of nine 381-millimeter (15.0 in) 50-caliber Model 1934 guns in three triple turrets; two turrets were placed forward in a superfiring arrangement and the third was located aft. Her secondary anti-surface armament consisted of twelve 152 mm (6.0 in) /55 Model 1934/35 guns in four triple turrets amidships. These were supplemented by four 120 mm (4.7 in) /40 Model 1891/92 guns in single mounts; these guns were old weapons and were primarily intended to fire star shells. Vittorio Veneto was equipped with an anti-aircraft battery that comprised twelve 90 mm (3.5 in) /53 Model 1939 guns in single mounts, twenty 37 mm (1.5 in) /54 guns in eight twin and four single mounts, and sixteen 20 mm (0.79 in) /65 guns in eight twin mounts.[4] EC 3 ter Gufo radar, which could detect surface targets at a range of 30 kilometers (19 mi) and aircraft at 80 km (50 mi), was installed in July 1943.[5]

The ship was protected by a main armored belt that was 280 mm (11 in) with a second layer of steel that was 70 mm (2.8 in) thick. The main deck was 162 mm (6.4 in) thick in the central area of the ship and reduced to 45 mm (1.8 in) in less critical areas. The main battery turrets were 350 mm (14 in) thick and the lower turret structure was housed in barbettes that were also 350 mm thick. The secondary turrets had 280 mm thick faces and the conning tower had 260 mm (10 in) thick sides.[3] Vittorio Veneto was fitted with a catapult on her stern and equipped with three IMAM Ro.43 reconnaissance float planes or Reggiane Re.2000 fighters.[6]

Service history

Construction

Vittorio Veneto was ordered under the 1934 construction program, and was named for the Battle of Vittorio Veneto, a decisive Italian victory over the Austro-Hungarian Empire in October–November 1918 during World War I.[7] Her keel was laid on 28 October 1934 at Cantieri Riuniti dell'Adriatico in Trieste, the same day as her sister ship Littorio. Vittorio Veneto was launched on 25 July 1937, and major construction was completed by October 1939. The fitting-out process was greatly delayed due to repeated changes to the design and shortages of heavy armor plate. Before she could begin sea trials, Vittorio Veneto was moved to Venice on 4 October to have her bottom cleaned of the fouling that had accumulated during the long fitting-out period, since the Venice Arsenal had the only drydock in Italy long enough to accommodate a ship the size of the Littorio class.[8]

On 17 October, with the cleaning completed, the dockyard personnel flooded the drydock to conduct stability tests. The new battleship moved to Trieste on 19 October, and her trials began on 23 October. The trials, which also included tests for the ship's weaponry, lasted until March 1940, after which some additional fitting-out work was completed.[9] She was delivered on 28 April, though she was not yet complete. On 1 May, Vittorio Veneto was sent to La Spezia for final fitting-out work, escorted by the destroyers Leone Pancaldo and Emanuele Pessagno. On 6 May, she was loaded with shells for her main battery; the loading work for the main and secondary guns lasted until 20 May. Later that day, she was transferred to Taranto, escorted by the destroyers Ascari and Carabiniere, where she joined the 9th Division of the Italian fleet. The following month, Italy joined the war against Britain and France, though it wasn't until 2 August that Vittorio Veneto and Littorio were formally declared operational.[10][11]

World War II

On 31 August – 2 September 1940, Vittorio Veneto sortied as part of an Italian force of five battleships, ten cruisers, and thirty-four destroyers to intercept British naval forces taking part in Operation Hats and Convoy MB.3, but contact was not made with either group due to poor aerial reconnaissance and no action occurred.[12][13][14] In addition, British aerial reconnaissance detected the oncoming Italian fleet and was able to escape. On 6 September, the fleet sortied again to attack a British force that had been reported leaving Gibraltar, but the British ships instead steamed south into the Atlantic.[15] A similar outcome resulted from the movement against British Operation "MB.5" on 29 September - 1 October; Vittorio Veneto, four other battleships, eleven cruisers, and twenty-three destroyers had attempted to intercept the convoy carrying troops to Malta.[12][16] In this operation, the Italian Regia Aeronautica (Royal Air Force) did locate the convoy, but the British were able to evade the Italian fleet.[17]

On the night of 10–11 November, the British Mediterranean Fleet launched an air raid on the harbor in Taranto. Twenty-one Swordfish torpedo bombers launched from the aircraft carrier HMS Illustrious attacked the Italian fleet in two waves.[18] The Italian base was defended by twenty-one 90 mm anti-aircraft guns and dozens of smaller 37 mm and 20 mm guns, along with twenty-seven barrage balloons. The defenders did not possess radar, however, and so were caught by surprise when the Swordfish arrived. The first wave struck at 20:35, followed by the second about an hour later.[19] Vittorio Veneto was undamaged in the attack, but three other battleships were hit, two of which were severely damaged.[18] The morning after the Taranto raid, Vittorio Veneto led the Italian fleet to Naples. There, she took over the role of fleet flagship, under the command of Admiral Inigo Campioni.[12]

Battle of Cape Spartivento

On 17 November, Vittorio Veneto and Giulio Cesare—the only operational Italian battleships—participated in an attempt to intercept the British Operation White convoy to Malta, though the forces made no contact.[20] On 26 November, the Italian fleet made another attempt to attack a British convoy, Operation Collar, which resulted in the Battle of Cape Spartivento (known as the Battle of Cape Teulada to the Italians). Vittorio Veneto, Giulio Cesare, six cruiser, and fourteen destroyers attempted to catch a convoy steaming to Malta. The British escort included the aircraft carrier Ark Royal, the battleship Ramillies, and the battlecruiser Renown; Italian aerial reconnaissance detected the escorts but exaggerated their strength and Campioni, under orders to not risk his two operational battleships against equal or stronger opponents, broke off the engagement shortly after it began. Vittorio Veneto briefly engaged several British cruisers and slightly damaged the light cruiser Manchester.[21][22] During the engagement, Ark Royal launched torpedo bombers against Vittorio Veneto, but the latter successfully evaded the torpedoes.[12]

Repeated British air attacks on Naples, one of which damaged the cruiser Pola, prompted the high command to move Vittorio Veneto and the rest of the major warships of the fleet to Sardinia on 14 December. They were returned to Naples six days later, however, after the high command concluded that removing the fleet to Sardinia would allow British convoys from Alexandria to reach Malta with relative ease.[23] On the night of 8–9 January 1941, the British launched an air raid with Vickers Wellington bombers on the Italian fleet in Naples, but the aircraft again failed to hit Vittorio Veneto; Giulio Cesare was slightly damaged by several near misses. Both ships were moved to La Spezia the next day, with Vittorio Veneto providing cover for Giulio Cesare. Vittorio Veneto was now the only operational battleship in the fleet.[12][23][24] Giulio Cesare was back in service by early February, as was Andrea Doria. The three battleships, along with eight destroyers, attempted to intercept Force H on 8 February, which was en route to bombard Genoa. The two forces did not encounter each other, and the Italian fleet returned to La Spezia.[12]

Battle of Cape Matapan

Vittorio Veneto returned to Naples on 22 March, and four days later led an attempt to attack British shipping off Greece, in company with eight cruisers and nine destroyers.[12] The fleet would be supported by the Regia Aeronautica and the German Fliegerkorps X (10th Air Corps).[23] This operation resulted in the Battle of Cape Matapan; the engagement began when the Italian 3rd Division—comprising the two Trento-class heavy cruisers and Bolzano and commanded by Vice Admiral Luigi Sansonetti—encountered the British 15th Cruiser Squadron. Iachino attempted to maneuver Vittorio Veneto to the east of the British cruisers while they were distracted with Sansonetti's cruisers, but HMS Orion spotted the battleship before she could close the trap. Vittorio Veneto immediately opened fire and quickly found the range, but only inflicted splinter damage on Orion, which fled to the south, back toward the main British fleet. Misfires in Vittorio Veneto's forward-most turret forced her to cease firing temporarily. The Italian gunners quickly returned the guns to action, however, and resumed their bombardment of the British cruisers. Poor visibility and smokescreens hampered the accuracy of Vittorio Veneto's gunners and they scored no hits, though they straddled the cruisers several times. In the course of this phase of the battle, she had fired 92 rounds from her main battery.[25]

During this period of the battle, torpedo bombers from the carrier HMS Formidable arrived on the scene, and their attack forced Vittorio Veneto to break off the engagement with the British cruisers to take evasive action. She evaded the torpedoes, but the attack convinced Iachino that the Mediterranean Fleet was at sea, which prompted him to end the operation and return to port. The British launched several air attacks against the Italian fleet in an attempt to slow down Vittorio Veneto, including land-based Blenheim bombers from Greece and Crete. Later in the afternoon Formidable launched a second strike, and at 15:10 one of her Swordfish hit Vittorio Veneto on her port side, aft.[26] The Italian anti-aircraft gunners shot the plane down after it launched its torpedo. The hit sheared off the port side propeller, damaged the shaft, jammed the port rudder, and disabled the aft port pumps. It also caused severe flooding—some 4,000 long tons (4,100 t) of water entered the ship—which gave her a 4–4.5 degree list to port, and forced her to stop for about ten minutes. While she was immobilized, a Blenheim bomber dropped a bomb that landed near her stern; the blast caused further, minor damage to stern.[27][28]

The damage control parties had great difficulty in controlling and reducing the flooding, since they could only use emergency hand pumps. Some forward and starboard voids were counter-flooded to reduce the list. In the meantime, engine room personnel were able to restart the starboard shafts and steering could be effected with the backup hand-steering gear.[29] After she got back underway, she was able to slowly increase her speed to 20 knots (37 km/h; 23 mph) using only her starboard shafts. While the Italian fleet was withdrawing, Formidable launched another air strike of nine Swordfish in an attempt to slow Vittorio Veneto down. But instead of hitting the Italian battleship, they struck the cruiser Pola, leaving her dead in the water. Vittorio Veneto returned to port while two cruisers and several destroyers were detached to protect Pola; all three cruisers and two destroyers were sunk in a furious night action at very close range with the battleships Valiant, Warspite, and Barham.[29] Vittorio Veneto meanwhile reached Taranto on 29 March, where repairs lasted until July.[30] She was not fully operational again until August.[31]

Later operations

Vittorio Veneto and Littorio participated in an unsuccessful sortie to intercept British forces on 22–25 August. The British had intended to mine Livorno and launch an air raid on northern Sardinia, but Italian agents in Spain warned the Regia Marina of the British operation when it departed Gibraltar. The Italian fleet positioned itself too far to the south, however, and aerial reconnaissance failed to locate the British.[32] A month later, Vittorio Veneto led the attack on the Allied convoy in Operation Halberd on 27 September 1941, in company with Littorio, five cruisers, and fourteen destroyers. The British had hoped to lure out the Italian fleet and attack it with a powerful convoy escort centered on the battleships Rodney, Nelson, and Prince of Wales. It too ended without contact with the British fleet; neither side located the other, but Italian torpedo bombers hit Nelson. At 14:00, Iachino cancelled the operation and ordered the fleet to return to port.[33]

On 13 December, she participated in another operation to escort a convoy to North Africa, but the attempt was broken off after a British radio deception effort convinced the Italians that the British fleet was in the area. While returning to port the following day, Vittorio Veneto was torpedoed by the British submarine HMS Urge in the Straits of Messina. Urge fired a spread of three torpedoes, but only one hit on her port side. The torpedo tore a hole 13 m (43 ft) long and caused over 2,000 metric tons (2,000 long tons; 2,200 short tons) of water to flood the ship, though the ship's Pugliese torpedo defense system successfully contained the explosion. Vittorio Veneto took on a 3.5 degree list to port and was down by 2.2 m (7 ft 3 in) by the stern. Some counter flooding of a compartment on the starboard side abreast of the forward-most turret reduced the list by a degree, and she was able to steam under her own power back to port.[34] She returned to Taranto for repairs, which lasted until early 1942.[35]

On 14 June, Littorio participated in the interception of the Operation Vigorous convoy to Malta from Alexandria. Littorio, Vittorio Veneto, four cruisers and twelve destroyers were sent to attack the convoy.[36] The British quickly located the approaching Italian fleet and launched several air strikes early on 15 June with Wellington and Bristol Beaufort bombers in an attempt to prevent them from reaching the convoy. The aircraft scored no hits on the battleships, but they did disable the cruiser Trento, which was later sunk by a British submarine. Later that morning another air attack, this time B-24 Liberators from the USAAF, occurred. The high-level bombers scored one hit on Littorio and several near misses around her and Vittorio Veneto, but neither ship was seriously damaged. Another British strike with Beauforts arrived shortly thereafter, but Italian and German fighters had since arrived and they shot down two Beauforts and damaged five others. By the afternoon, Iachino had concluded that he would not reach the convoy before dark, and so he broke off the operation. On the return voyage, another British air attack succeeded in torpedoing Littoiro.[37]

Fate

On 12 November, Vittorio Veneto was moved to Naples from Taranto in response to the Allied invasion of North Africa.[35] While en route, the British submarine HMS Umbra unsuccessfully attacked Vittorio Veneto.[38] An American air raid on the harbor on 4 December prompted the Italians to withdraw the fleet to La Spezia, where it remained for the rest of Italy's active participation in the war.[35] On 5 June 1943, Vittorio Veneto was badly damaged by an American air raid on La Spezia; she was hit by two large bombs toward the bow, though only one detonated. That bomb passed through the ship and exploded under the hull, causing serious structural damage. The damage forced her to be transferred to Genoa for repair work, since the dockyard in La Spezia had also been damaged by the attack.[39] On 3 September, Italy signed an armistice with the Allies, ending her active participation in World War II. Six days later, Vittorio Veneto and the rest of the Italian fleet sailed for Malta, where they would be taken into internment for the remainder of the war. While en route, the German Luftwaffe (Air Force) attacked the Italian fleet using Dornier Do 217s armed with Fritz X radio-controlled bombs. Vittorio Veneto was undamaged but Littorio—by now renamed Italia—was hit and damaged and her sister Roma was sunk in the attack.[40][41]

Vittorio Veneto remained in Malta until 14 September, when she and Italia were moved to Alexandria, Egypt and then to the Great Bitter Lake in the Suez Canal on 17 October. The two battleships remained there until 6 October 1946, when they were permitted to return to Italy. Vittorio Veneto went to Augusta, Sicily before moving to La Spezia on 14 October. In the Treaty of Peace with Italy, signed on 10 February 1947, Vittorio Veneto was allocated as a war prize to Britain. She was paid off on 3 January 1948, stricken from the naval register on 1 February, and subsequently broken up for scrap.[35] Vittorio Veneto had been the most active Italian battleship of the war, having participated in eleven offensive operations.[42] Twelve 90 mm anti-aircraft guns taken from Vittorio Veneto were reused by the Yugoslav People's Army (JNA) as armament of its Žirje Island coastal artillery battery.[43] The battery surrendered without resistance to the Croatian National Guard on 14 September 1991, during the Croatian War of Independence,[44] and played a pivotal role in 16–22 September Battle of Šibenik, helping defend the city of Šibenik against the JNA.[43]
