135 mm/45 Italian naval gun

The Cannone da 135/45 OTO 1937 was a 135 mm (5.3 in) 45-caliber naval gun built for the Regia Marina in the late 1930s. Built as a response to the French Canon de 138 mm Modèle 1929, it was meant to have the same range as the widespread 120 mm gun, but with less muzzle velocity and less dispersion.
