A jet propulsion system for a submersible vehicle, such as a submarine includes a propulsion unit mounted away from the stem of the submersible. Generally, the propulsion system consists of a set of blades secured to a hub within a shroud. Combining such a propulsion system with a surface texture treatment greatly reduces overall drag while improving the submersible's efficiency. Further, such an arrangement contributes to the submersibles stealthy characteristics. An additional hub and set of high-speed blades capable of generating a supercavity may be added to achieve supercavitation. The propulsion system can be varied to include a pumpjet and/or a centrifugal force blade system.
