Submarine Sonary systems include a towed sonar array that is deployed behind a moving submarine. The outboard sensor assembly (OSA) monitors the passage of the towed array during deployment, retrieval and relays the information to the submarine personnel. TRI/Austin used a pressure compensation system and composite materials to develop a new type of outboard sensor assembly. The system is lower in cost, easier to manufacture in quantity, lighter weight, less likely to leak, and with a lower failure rate than conventional systems.
