The Andrea Doria class was a class of dreadnought battleships of the Regia Marina (Italian Royal Navy). Only two were built, in the La Spezia and Castellammare shipyards, in Italy, between 1912 and 1915.
Although launched in World War I, the class did not see any service against the Central Powers. They were modernized during 1937-1940, between the wars, and both participated in World War II, at the First Battle of Sirte, and on convoy duty.

Design
When first built, the 2 ships were nearly identical in general design.
General characteristics
Prior to their extensive modernization from 1937 to late 1940, both members of the Andrea Doria class weighed 22,956 tons. When they were fully loaded, the battleships weighed as much as 24,729 tons. Following their modernizations, the battleships weighed 26,434 tons and 29,391 tons while fully loaded. The ships were 168.96 m (554.3 ft) in length. Their beam was 28.03 m (92.0 ft) while their draft was 8.58 m (28.1 ft). They each had a crew of 1,233 men and officers when they were commissioned into the Regina Marina. Following their modernization, they each had a crew of 1,485 men and officers.[1]
Propulsion
When they were first built, the Andrea Doria class was equipped with a steam turbine system and had 20 boilers and 4 shafts. This totaled to an output of 30,000 shaft horsepowershp. Following their modernization, the battleships were still equipped with a steam turbine system but had 8 Yarrow-type boilers and 2 shafts, which produced a total of 75,000 shaft horsepower. The battleships could travel with speeds up to 23 knots (43 km/h) when they were first built.[2] After they were modernized, the Andrea Doria class could travel as fast as 27 knots (50 km/h),[1] or 17% faster.
Armament
The Andrea Doria class's main armament, when first built, was 13 305 mm (12 in) guns in three triple and two double turrets. They were also equipped with 16 152 mm (6 in) guns, 13 76 mm (3 in) guns, 6 76-millimetre (3.0 in) anti-aircraft guns, and 3 450 mm (18 in) torpedo tubes. After their modernization, the battleships had 10 320 mm (12.6 in) guns located in two triple and two double turrets, 12 135 mm (5.3 in) guns in four triple turrets, 10 90 mm (3.5 in) anti-aircraft guns, 15 37-millimetre (1.5 in) anti-aircraft guns, and 16 20-millimetre (0.79 in) anti-aircraft guns.[1][2]
Armor
The Andrea Doria class was equipped with 254-millimetre (10.0 in) armor at the Belt, while her turrets were plated with 280-millimetre (11 in) armor. The battleship's Deck armor was 98 mm (3.9 in).[1]
Ships
There were 2 ships in the class:
- Andrea Doria, launched in 1913. She served at the First Battle of Sirte and as a convoy escort until interned after the armistice in September 1943. She served as the Italian flagship in the 1950s.[3]
- Caio Duilio was launched in 1913, and was damaged at the Battle of Taranto by British aircraft. Because of this and fuel shortages, she was out of the war following the armistice. She was later a training ship and flagship of the Italian Navy until scrapped.[3]
