During the Cuban missile crisis of October 1962 the Soviet Union stationed submarines in the region in order to be able to sink American ships in the event of war. But communication between the submarines and Soviet high command was hard. Electrically conductive salt water absorbs radio waves, so exchanging information with Moscow required the submarines to ascend to periscope depth in waters patrolled by American planes and ships. In the decades that followed navies continued to be dogged by the difficulty of establishing underwater data links. Subsea networks being developed by America and its allies will shuffle data between submarines, aquatic drones and sensors via devices that sway beneath the water or bob on its surface. They will make it possible to detect enemy vessels and mines and allow submarines to link up with surface ships, aircraft and distant command centres, says Vernon Clark, America's former chief of naval operations. Undersea networks could also monitor waterways and gather scientific data.
