Lockheed Martin has announced that it's completed a critical design review for a system that enables submarine communication while below periscope depth. Part of the US Navy's Communications at Speed and Depth Program, buoys are launched by the sub, which can then connect nearby to military networks or satellites. The 40-inch long buoys can either be launched from the sub itself, shuttling data back and forth via miles-long cables, or dropped from aircraft. If the latter, communications is established using an acoustic messaging system similar to SONAR.via engadget

Deploying Buoy Communications for Submarines.
This design strategy seems so simple I have to wonder why it wasn't thought of before...
