History
The first notable anti-aircraft gun for the Regio Marina (Royal Italian Navy) was the 40 mm/39 Vickers-Terni mod.1915/1917. A licensed model of the British Vickers 2-pounder Mark II "pom-poms", the guns were starting to show their age by the 1930s. While capable against the slower and fragile biplanes of World War I, the new generation of all-metal monoplanes was going to render the guns obsolete as the British themselves would learn in World War II. The Regio Marina started to seek a replacement, but in the meantime, they decided to make some upgrades to the design. The Modif. 1930 mount variant replaced the 25-round feed belts with 50-round drums and the rate of fire was increased from 1,920 rounds per minute to 2,000 rounds per minute. It was only two years later when the 37 mm/54 Breda Mod.32 was adopted, but the state of Italian industry meant that it wasn't fully phased out by World War II and was still present on warships such as the RN Dardo and RN Leone.
