The Cannone da 190/45 was a family of Italian naval guns that were the secondary armament of two classes of armored cruisers of the Regia Marina and Hellenic Navy built before World War I. The cruisers that they were aboard saw action in both world wars. It is also believed that spare guns may have been used as coastal artillery during World War II.[1]
There were actually two guns from different manufacturers that were classified as the Cannon da 190/45. One was the Model 1906 produced by Vickers which was based on their Mark "D" gun, while the second was the Model 1908 which was produced by Armstrong and based on their Elswick Pattern "C" gun.[2] The dimensions for both guns were similar and both used the same projectiles and powder charges.[3]
Construction of the Vickers gun is believed to have been 'A' tube, inner 'A' tube, wire winding for 75% of their length, 'B' tube and jacket. A Welin breech block was used and separate loading bagged charges and projectiles were used. The two classes of armored cruisers that carried these guns were the Pisa-class and the San Giorgio-class.
