A self-powered towed underwater sensor is provided. The sensor has a shielded casing which encloses an electric generator. The generator is connected to an impeller that is located at the midpoint of the easing. The impeller is covered by a shroud which minimizes the disturbance of the water by the impeller. The easing contains shield which absorbs Electromagnetic radiation produced by the generator. The shield is placed around the generator A towed cable is connected to the forward end of the easing. Pie towed cable is made of a material having a high tensile strength to facilitate towing. A fiber optic cable is located within the towed cable and runs the length of the cable, specifically for transmission of received data from the attached sensor the towing craft. The use of fiber optics prevents interference by electromagnetic radiation in the environment through which the cable passes and there is no power lead that could conduct interference into the array.
