The Cannone da 152/45 modello 1911 was an Italian naval gun built by the Ansaldo company. It formed the secondary armament of the two Andrea Doria-class dreadnought battleships built during World War I. A number of guns were also converted to siege artillery and coastal artillery roles and served during both world wars.
