Submerged Submarine Communications Link Established

The U.S. Navy has successfully conducted the first large-scale test of a technology that enables commanders to communicate with a submerged submarine, regardless of its speed and depth. In the final evaluations of the Deep Siren tactical paging system, which were held in June and August, a Navy submarine deployed special communications buoys that reached the surface to establish a communications link between the vessel and the test team in Norfolk, Virginia. The Deep Siren buoys can receive and transmit satellite communications, converting them to acoustic signals.
