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. (taken from Wikipedia)

To differentiate: Andrea Doria has AA guns on the middle of #2 and #3 turrets
