Abstract: An antenna arrangement for a submerged submarine includes an independently unctioning underwater vehicle free of any tethered connection to said submarine, a buoy member having a hydrodynamic shape, an antenna mounted on the buoy member, the antenna enabling collection and transmission of at least global positioning data and radio frequency communications, a releasable connector for securing the buoy member to said underwater vehicle in a primary non-deployed position, and a tether connection the buoy member to the underwater vehicle in a secondary deployed position. Release of the connector deploys the buoy member and the antenna such that the hydrodynamic shape of the buoy member raises the buoy member to a data collection and transmission position at a surface of the water.
