ABSTRACT:
The present invention relates to an underwater weapon having a barrel with n opening through which a projectile is discharged. The weapon further has an apparatus for pressurizing the interior of the barrel to a pressure greater than the ambient pressure to keep water from entering the gun barrel at any point around the circumference of the muzzle opening. The pressurizing apparatus includes a source of gas, a pressure regulator for adjusting the flow of the gas and the pressure within the barrel, and a distribution network for distributing the gas near the muzzle opening and at an end of the barrel remote from the muzzle opening.
