A propulsion system for undersea vehicles comprises a pair of counter-rotating low speed impellers driven from a spider shaft rotating at relatively high speed. The reduction is accomplished by a variable speed reducing and torque transmitting device which allows infinite resolution for speed control, including a zero speed setting, while maintaining a constant high speed at the input spider shaft. Attitude of the vehicle is controlled by regulated inlet ports and roll control is regulated by increasing the speed of one impeller and decreasing the speed of the other. The sea water utilized for the attitude is also used for propulsion. Control systems within the vehicle utilize an electro-pneumatic-hydraulic system complex.
