I saw that in your (great) game the italian oto melara 76mm cannon makes some appearance. Still its maximum range is limited to - i think - 5nm.
Actually, with the enhanced VULCANO ammunition, this cannon can reach up to 40km that is ~21nm. Also the rate of fire of this cannon in the game is quite low, while the "Super Rapido" version should be able to fire 120 rounds per minute.
On the other hand the 127/64mm OTOBREDA cannon should be able to fire VULCANO ammunition up to 100km, that is basically the range of an Harpoon missle. It would be cool to have a ship equipped with such a weapon, maybe in a DLC, because it really seems a game-changing improvement that could bring back usefullness in naval artillery.
