Presently mariners have to reach the water level corresponding to the periscope end and send their communication which is dangerous as they are prone to attack near the water surface. The new system ensures safety of sailors and effectiveness and quality of communication. When once the sailors complete texting, buoys could be cut and disconnected from the submarine.
An extension of this type of buoy communication would include underwater robots for sending distress signals related to sunken ship, oil leakage, lost track, diving mishap, etc., in the near future.
