The concept involves deploying RF network node buoys\u2014dropped from aircraft or ships, for example\u2014that would be connected via thin underwater fiber-optic cables. The very-small-diameter fiber-optic cables being developed are designed to last 30 days in the rough ocean environment\u2014long enough to provide essential connectivity until primary methods of communications are restored.<\/p>\n<p>\u201cPhase 1 of the program included successful modeling, simulation, and at-sea tests of unique fiber-cable and buoy-component technologies needed to make such an undersea architecture work,\u201d said John Kamp, program manager in DARPA\u2019s Strategic Technology Office. \u201cTeams were able to design strong, hair-thin, buoyant fiber-optic cables able to withstand the pressure, saltwater, and currents of the ocean, as well as develop novel power generation concepts.\u201d<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.darpa.mil\/news-events\/2017-01-05\">http:\/\/www.darpa.mil\/news-events\/2017&#45;01&#45;05<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>DARPA\u2019s Tactical Undersea Network Architecture (TUNA) program recently completed its initial phase, successfully developing concepts and technologies aimed at restoring connectivity for U.S. forces when traditional tactical networks are knocked offline or otherwise unavailable.
