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.[2]
