Cool DARPA Stuff: The Big "T.U.N.A." Keeping Tactical Data Networks Open

TUNA (Tactical Undersea Network Architecture):
TUNA seeks to develop and demonstrate novel, optical-fiber-based technology options and designs to temporarily restore radio frequency (RF) tactical data networks in a contested environment via an undersea optical fiber backbone. The concept involves deploying RF network node buoys—dropped from aircraft or ships, for example—that 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—long enough to provide essential connectivity until primary methods of communications are restored.
