DARPA tests buoy network for fallback military comms at sea
It doesn't matter how many war machines you have under your command if you can't relay orders to their operators. Maintaining communications is just as important as firepower, and DARPA wants the armed forces to have as many contingencies as possible when networks go down or are actively jammed. Setting up a fallback network is even trickier on the open ocean, but the agency's Tactical Undersea Network Architecture (TUNA) program is well on its way to a solution. That solution being a collection of "node" buoys, deployed from ships or planes, that are tethered together by fiber optic cables to create a radio frequency data network.
