I demonstrate a new and unique design for an underwater 360 cannon. This cannon was built with stealth in mind. The cannon can be completely hidden under the ocean floor.
This cannon is unique because I believe it is the first true underwater cannon built in minecraft. By "true underwater cannon", I mean the first cannon where both the TNT missile(s) and TNT propellent are actually placed in the ocean. Only the wiring and firing controls are placed inside a casing under the water.
The cannon is short to medium range and contains my modified version of EtherImp's variable timer system. If actually used in PVP, it would be considered a defensive cannon designed to destroy players crossing the ocean via boat.
