WELSE S.p.A., Genoa, Italy has developed an Antisubmarine Warfare Area System (ASWAS) as an underwater defense system for naval bases, coastal installations, harbors, offshore platforms, straits, and sea areas. The ASWAS was designed to operate as an underwater gate against possible attacks from submarines and minisubmarines. It uses a barrier of sensors deployed on the sea bottom and linked via cable to an ashore-based control station. The system is able to interdict the access to naval bases or harbors and/or control the underwater traffic through straits and sea areas of interest. The underwater barrier is composed of sensor units providing a double sequential detection of the underwater vehicle or submarine, based on the activation of a magnetic sensor and the subsequent triggering of an acoustic device as a confirmation. The control station is based on a single manned console.
