The capability of Sea Tentacle as a comms platform is extensive and meets the objective for communication requirements.

The comms suite is designed to be fully interoperable with the numerous DoD and Joint communications system that makeup the global information grid and that fuel the ForceNET paradigm and net-centric warfare.

Sea Tentacle’s ability to perform distributed net-centric ASW will be made possible through its acoustic modem/transducer that is capable of maintaining direct comms with the underwater acoustic sensor grid at nominal ranges.  Gateway nodes extend this capability, allowing Tentacle to have a increased standoff range.
