Abstract
A baffled muzzle brake and seal system for submerged gun operation includes a muzzle brake chamber mounted to the muzzle of a submerged gun barrel. A baffle assembly mounted within the chamber deflects the propellant gasses produced by operation of the gun and sabot fragments into an annular cher surrounding the baffle assembly while allowing passage of a projectile through the assembly. A valve seal in the muzzle end of the muzzle brake chamber cycles between a fully open condition, to allow passage of the projectile, and a fully closed position, to seal the muzzle brake chamber against the entry of water. At least one pressurized air input allows the muzzle brake chamber to be pressurized when the seal is not in the fully closed position, thereby preventing entry of water. A gas exhaust provides a means for removing propellant gasses from the chamber.
