The Cannon 76/40 Model 1916 was a widely used naval gun on ships of the Royal Italian Navy during World War I and World War II. A very versatile weapon, it was used as primary, secondary and tertiary armament on a number of ship classes, while other ship classes had a shortened version of it, the Cannon 76/30 Model 1915. After being replaced aboard ships of the Royal Italian Navy it saw widespread use on land in a number of different roles such as coastal artillery, anti-aircraft gun and railroad gun during World War II.
