Abstract : A low frequency submarine communication system which utilizes the submarine body as part of the antenna. The antenna is coiled around the submarine hull and utilizes the hull as the core for low frequency (below 1000 Hz) communication. The system allows communication with other vehicles below, on, or above the surface without impeding submarine operation (speed or depth) and the system greatly decreases chances of unwanted detection of the submarine.
