The patent relates to a steerable propulsion system for maneuvering a submarine vehicle in close proximity to the bottom of a body of water with minimal disturbance of the bottom material. It includes a series of four thrust producers spaced about the center of buoyancy of the submarine vehicle. Controls limit the direction of thrust application to prevent the water flow produced by the thrust producers from impinging upon the bottom.
