New System Concept for Long Range Underwater Communication of Tactical Data

1A new system concept is proposed which could greatly improve the Navy's ability to conduct Anti-Submarine Warfare (ASW). The concept involves the long range communication of the Battle Group's tactical data to deeply submerged submarines via a sophisticated and very high performance acoustic data link. The proposed system will operate in conjunction with Link-11 and will transmit the same tactical data to submarines that the rest of the Battle Group receives on a real-time basis. A new dual purpose Data Terminal Set (DTS) is required to modulate/demodulate the Link-11 waveform, as well as the new waveform required for reliable underwater operation. No changes are necessary to the NTDS. This is an extremely important capability that the Navy currently does not have.
