Abstract
The underwater gun assembly of this invention has an acceleration barrel and a firing gun. Percussion-initiatable cartridges are carried to the acceleration barrel by a stream of water. Each cartridge has an outside diameter which is nearly equal to the inside diameter of the bore in the barrel whose length is such as to allow the water pressure to optimally accelerate each cartridge in its trajectory through the barrel. The firing gun is detachably coupled to the barrel by a quick-disconnect coupling means. The detachable coupling means preferably includes a non-metallic resilient member which absorbs the shock waves from the ambient charge explosions, thereby preserving the integrity of the coupling means in respect of its detachable characteristics.
