The US Navy has identified an urgent need for improved communications on Unmanned Underwater Vehicles (UUV). PMS 406 seeks improved communications and GPS antennas for the Razorback UUV from HF (3 MHz) up to L-band (2.4 GHz). During the Phase I effort, Physical Sciences, Inc. (PSI) successfully built and tested an integrated antenna solution that ensures reliable communication links from the UUV to LEO and GEO satellites, and surface ships up to 12 nmi. The complete Phase I deployer/antenna prototype stows within a 24” x 3.5” x 3” volume for low submerged drag, and weighs 9.3 lb. During the Phase II program, PSI will advance the development of the deployment mechanism and the antenna system with the goal of demonstrating a deployable communications system integrated with an existing UUV system analogous to the Razorback MUUV. The Deployable UUV Communications System (DUCS) will provide a tactical advantage for Navy assets by improving communications range and reliability. It will extend mission duration by reducing drag on the hull. It will improve crew safety on surface ships by increasing stand-off from minefields during EOD clearing. It will expand the weather windows for conducting surveillance and EOD operations.
