. The Littorio class ships were developed in response to the French s, and were armed with 381 millimetres (15 in) guns and had a top speed of 30 knots (16.3 m/s). The design was considered by the Spanish Navy, but the outbreak of World War II interrupted construction plans.

The first two ships, Littorio and Vittorio Veneto, were operational by the early months of Italy's participation in World War II. They formed the backbone of the Italian fleet, and conducted several sorties into the Mediterranean to intercept British convoys, though without any notable success. The two ships were repeatedly torpedo

Nevertheless, Italia and Vittorio Veneto reached Malta and were interned. The incomplete Impero was seized by the Germans after Italy withdrew from the war and used as a target, until she was sunk by American bombers in 1945. Italia and Vittorio Veneto were awarded to the United States and Britain, respectively, as war prizes. Italia, Vittorio Veneto, and Impero were broken up for scrap between 1947 and 1948.

 of 1922 allotted Italy an additional 70000 LT of total capital ship tonnage, which could be used in 1927–1929, while other powers were observing the "holiday" in battleship construction prescribed by the treaty. France, which was given parity with Italy, also possessed 70,000 tons of capital ship tonnage. Both countries were put under significant pressure from the other signatories to use their allotted tonnage to build smaller battleships with reduced caliber main batteries. The first Italian design, prepared in 1928, called for a 23000 LT ship armed with a main battery of six 381 mm (15 in) guns in twin turrets. They opted for this design because this allowed three ships under the 70,000-ton limit. Protection and radius of action were sacrificed for speed and heavy armament, though the Italians did not value range, as they operated primarily in the confined waters of the Mediterranean.

Later in 1928, the design staff prepared an alternative ship, with a displacement of 35000 LT, armed with 406 mm (16 in) guns and protected against guns of the same caliber. Funding was not allocated to begin construction, however, as the Italian Navy did not want to instigate an arms race with the French Navy. The London Naval Treaty

 of 1930 extended the building holiday to 1936, though Italy and France retained the right to build 70,000 tons of new capital ships. Both countries rejected British proposals to limit new battleship designs to 25000 LT and 305 mm (12 in) guns. After 1930, the Italian Navy abandoned the smaller designs altogether. By 1932, Germany had begun to build the ships, armed with six 280 mm (11 in) guns, and France had in turn laid down the s to counter them. The French vessels were armed with eight 330 mm (13 in) guns. In late 1932, Italian constructors responded with a design similar to the Deutschland class, but armed with six 343 mm (13.5 in) guns in triple turrets on a 18000 LT displacement.

The Italian Navy decided that the smaller design was impractical, and that a larger design should be pursued. A 26500 LT design was then prepared, which mounted eight 343 mm guns in twin turrets. This was ultimately abandoned in favor of a 35,000 ton design to be armed with 406 mm guns. The 406 mm gun was abandoned in favor of the 381 mm gun because there were no designs for the larger gun, which would delay construction. The 381 mm gun had been designed for the canceled . Ultimately, nine 381 mm guns in three triple turrets were adopted as the primary battery for the ships, on a displacement in excess of 40000 LT, despite the fact that this violated the established naval treaties.

General characteristics

The ships of the class varied slightly in dimensions. Littorio and Vittorio Veneto were 224.05 metres (735.1 ft) long between perpendiculars and 237.76 m (780.1 ft) long overall, while Roma and Impero were 240.68 m (789.6 ft) long overall. All four ships had a draft

 of 9.6 m (31.5 ft). Littorio displaced 40724 metric tons (40,080.7 LT) as designed and 45236 MT (44,521.4 LT) at full load. Vittorio Veneto displaced 40517 MT (39,877 LT) and 45029 MT (44,317.7 LT), respectively. Romas displacement increased slightly as compared to the other ships, to 40992 MT (40,344.5 LT) and 45485 MT (44,766.5 LT), respectively. As Impero was not completed, her final displacement is unknown. As built, the ships were fitted with bulbous bow

s. The engines were rated at 128200 shp and a top speed of 30 knots (16.3 m/s). On sea trials, both Littorio and Vittorio Veneto exceeded the design specifications for their power plant. Littorio reached 137649 shp and 31.3 kn (17 m/s), while Vittorio Veneto made 133771 shp and 31.4 kn (17.1 m/s), both at light loadings. In service, however, the ships averaged 28 kn (15.2 m/s). Figures for Romas speed trials have not been recorded. The ships carried 4140 MT (4,074.6 LT) of fuel oil, which enabled a maximum range of 4580 nautical miles (8,482.2 km) at a cruising speed of 16 kn (8.7 m/s). At 14 kn (7.6 m/s), the ships' range increased slightly to 4700 nmi (8,704.4 km). The entire machinery system accounted for about 5.6 percent of the total displacement.

 was one shot every 45 seconds.

The ships' secondary battery consisted of twelve 152 mm (6 in) L/55 Ansaldo Model 1934 guns in four triple turrets. Two were placed abreast the No. 2 main battery turret and two on either side of the rear turret. These guns fired a 50 kg (110.2 lb) AP shell at a muzzle velocity of 910 m/s. They could elevate to 45 degrees, permitting a maximum range of 25740 m (84,448.8 ft). They had a rate of fire of slightly better than four rounds a minute. Four 120 mm (4.7 in) L/40 guns supplemented the 152 mm guns. The ships' anti-aircraft armament was composed of a powerful battery of twelve 90 mm (3.5 in) L/50 guns closely arranged amidships, twenty 37 mm (1.5 in) L/54 guns, and sixteen 20 mm (0.78740157480315 in) L/65 guns. The 90 mm guns provided long-range anti-aircraft protection, and were mounted in quadriaxially stabilized single turrets. They had a rate of fire of 12 rounds per minute and had a ceiling of approximately 10800 m (35,433.1 ft). The 37 mm and 20 mm guns were designed for close-range defense and had effective ranges of 4000 m (13,123.4 ft) and 2500 m (8,202.1 ft), respectively.

 was designed to defeat 380 mm shells at ranges over 16000 m (52,493.4 ft), and was inclined at 11 degrees. The belt was layered as follows: a 70 mm (2.8 in) hardened steel belt was used to de-cap armor-piercing projectiles. A 250 mm (9.8 in) wide gap separated the outer layer from the main belt armor, which was 280 mm (11 in) thick and was backed with 50 mm (2 in) of timber and 25 mm (0.984251968503937 in) skin plating. Another 140 mm (5.5 in) wide gap separated the main belt from a 36 mm (1.4 in) thick splinter screen. Another 25 mm thick screen was placed further inboard. The main section of the belt armor was closed on either end by 70 mm (2.8 in) thick transverse bulkheads. The bow was protected by a 60 m (196.9 ft) thick belt, while the stern was given 125 mm (4.9 in) of armor protection.

Horizontal protection over the magazine consisted of a 162 mm (6.4 in) thick armored deck. Over the machinery spaces, the deck was reduced in thickness to 110 mm (4.3 in), and on the outboard portions of the ships, the deck was reduced further to 90 mm (3.5 in). The aft steering rooms and auxiliary machinery spaces were protected by a 105 mm (4.1 in) thick deck. The main conning tower

s that housed the turret assemblies for the 381 mm guns were protected with 350 mm (13.8 in) thick armor, while below deck the thickness was reduced to 280 mm. The faces of the main battery turrets were 350 mm thick, with 200 mm (7.9 in) thick sides and roofs. The secondary gun turrets were housed in barbettes 150 mm (5.9 in) thick above deck and 100 mm (3.9 in) thick below deck. The turret faces were 350 mm thick, with 75 millimetre thick sides and 150 mm thick roofs. Below the third deck, neither the primary or secondary barbettes were protected by armor. The anti-aircraft guns were protected with gun shields ranging in thickness from 12 mm (0.47244094488189 in) to 40 mm (1.6 in).

Pugliese torpedo defense system

All four ships incorporated a unique underwater protection system named after its designer, Umberto Pugliese. A 40 mm thick torpedo bulkhead

 extended inboard from the base of the main belt before curving down to meet the bottom of the hull. This formed a void which housed an empty drum 380 mm (15 in) wide with 6 mm (0.236220472440945 in) thick walls; the rest of the void was filled with liquid. The drum ran the length of the torpedo defense system, and was designed to collapse to contain the explosive pressure of a torpedo hit. The torpedo bulkhead would prevent any splinters or explosive effects from entering the ships' vitals. The system was designed to protect the ship from torpedo warheads up to 350 kg (771.6 lb).

The system did not perform as effectively as expected, however. This was due to two major defects in the design. The riveted joint that connected the interior torpedo bulkhead to the bottom of the hull was not strong enough to sustain the tremendous shear loadings associated with a direct contact explosions. The joints failed even in cases of non-contact explosions; this prevented the hollow drum from collapsing as designed and resulted in massive flooding. The fineness of the hull shape prevented the 380 mm thickness from being maintained for the entire central citadel; the width of the drum was reduced significantly abreast of the main battery, down to 228 mm (9 in). The ability of the drum to absorb explosive shock correspondingly fell in relation to its size.

. The battleship was flooded with some 4000 MT (3,936.8 LT) of water, though she got underway after ten minutes and eventually reached Taranto on 29 March. Repairs lasted until July.

Littorio and Vittorio Veneto had both returned to active duty by August 1941, and on the 22nd the two ships sortied to attack a convoy. They returned to port without encountering any British forces, however. On 26 September, the two battleships attempted to intercept the Operation Halberd

. Roma joined the fleet shortly after the attacks on the two convoys, and joined her sisters for the move to La Spezia. There, she replaced Littorio as the fleet flagship.

In June 1943, a series of Allied air raids attacked La Spezia in an attempt to neutralize the three battleships. On 5 June, she was hit by two large bombs that struck her port side. She was transferred to Genoa for repairs, which were not completed before the Armistice that ended Italian participation in the war. Littorio was hit by three bombs on 19 June, a week after her sister was damaged. She was renamed Italia after Benito Mussolini

's regime collapsed. Roma was damaged during the 5 June attack and again in a third attack on 23 June. In September 1943, following the withdrawal of Italy from the war, all three ships and a significant portion of the Italian fleet left port to be interned in Malta. While en route, German bombers laden with Fritz-X radio-guided bombs attacked the formation. One hit Italia in the bow forward the main battery turrets, causing serious damage. Two hit Roma; one passed through the ship and exploded under her keel, and the second hit near the forward magazines. The bomb detonated the magazines, causing a massive explosion that destroyed the ship with heavy casualties.

Italia and Vittorio Veneto successfully reached Malta, where they remained until 14 September, when they were transferred to Alexandria. They remained at the Great Bitter Lake

 for the rest of the war. On 6 June 1946, Vittorio Veneto steamed to Augusta in Sicily, where, under the Treaty of Peace with Italy, she was allocated to Britain. On 14 October 1946, she was moved to La Spezia, paid off on 3 January 1948, and broken up for scrap. Italia left Great Bitter Lake on 5 February 1947, to join her sister in Augusta. Allocated to the United States, she was stricken on 1 June 1948 and scrapped in La Spezia. The incomplete Impero had meanwhile been seized by the retreating Germans in 1943, who used her as a target, until she was sunk by American bombers on 20 February 1945. In October 1947, the ship was raised and towed to Venice

. Franco concluded several agreements with the Italian government that would have seen the building of four Littorio class battleships in Spain. The Italians promised to provide all necessary technical and material support for the construction of the ships. The Italian Navy pushed to modernize and enlarge the existing shipyards in Spain, so that they could handle a vessel as large as the Littorio class. The project was abandoned after Italy became involved in World War II, and as a result of limited Spanish industrial capacity.

The design was for a 42000 MT (41,336.5 LT) ship armed with nine 406 mm guns in triple turrets. The Italians did not disclose the specifications of the Pugliese system and instead used a multiple-torpedo bulkhead
