Abstract
An apparatus and method for sealing the barrel of an underwater gun between firings is disclosed. The apparatus comprises a turbine that is disposed at the outlet of the muzzle of the gun. The turbine draws in water and, in various embodiments, either (a) vaporizes it, forming a vapor barrier along the spin axis that keeps water out of the barrel, (b) expels it radially, thereby re-directing it so that it does not enter the barrel, or (c) generates water jets that prevent water from entering the barrel.
