History
The Regia Marina (Royal Italian Navy) was ahead of the curve to an extent when it came to warship design in the early 1900s. The idea of an all-big-gun-battleship that was codified with the launch of HMS Dreadnought as the new standard for battleship design was first proposed by Italian officer Vittorio Cuniberti in 1903, though the Regia Marina were hesitant to adopt this new design until 1909 when they laid down their dreadnought RN Dante Alighieri. Like the Royal Navy, the Italians decided to use 12-inch (305 mm) guns. The 305 mm/46 Vickers model 1909 was one of the two 12-inch guns used by the Regia Marina along with the 305 mm/46 Armstrong model 1909. While they were used by Regia Marina interchangeably on their dreadnoughts, the two designs were not compatible. The Vickers Mk. "G" was first purchased for the RN Andrea Doria before licensed production began at Vickers-Terni. These guns were used on the Conte di Cavour and Leonardo da Vinci. The Vickers model was a full wire wound with inner A, A, and B tubes along with the jackets and rings and the hydraulic mount weighed 62.5 tons. Like the Armstrong model, it used a Welin breech block.
The three ships didn't see much service during World War I due to the Regia Marina's doctrine of keeping their battleships in reserve in the southern Adriatic Sea instead of engaging in combat in the more northern parts that could be littered with enemy mines and submarines. The Leonardo da Vinci was the first ship to be lost, suffering a magazine detonation in port at Taranto. After the war, the remaining two ships would have their guns bored out to 320 mm (12.6-inch). A few turrets were removed during this modernization and would see service in the coastal defense role during World War II.
