The Type 94 is a Japanese battleship gun, the heaviest in history. Pirates came with the schematics for the gun in one of the many air and sea raids on Japanese transport aircraft and boats. It is the heaviest naval gun in service with any faction in the country. However, it is very rare and replacement parts are difficult to come by. No modifications have been made for the gun itself, but the turrets are usually very personalised to the ship's needs.
