Hot Air About Protecting Subsea Cables
A subsea cable is like a long piece of string. Except the world's cables total about 1.5 million kilometers. Anything shaped like that is inherently indefensible. The Big Huff and Puff is that if we place sensors on or near the cables, presto, problem solved. Not a chance. All it takes is a technologically sophisticated and patient adversary to send out unmanned drones to locate the cables in deep sea where they lie exposed on the ocean's floor. Record the coordinates or drop a homing beacon. When the war is about to go from cold to hot, release underwater drones with charges to attach themselves to these cables and blow them up. Sensors are of limited value because no country or military alliance has sufficient vessels to station them close enough to every point of possible attack.
