non-trivial strategic advantage because of technology

since lidar could be used by satellites, ships and aircraft for sea floor mapping 

that shows that lasers could penetrate deep into sea water 

then submarines should able to use underwater lasers to communicate with satellites, aircraft and ships 

which could enable submarines to communicate with command and other units in real time while deep underwater 

which could change not only submarine warfare but naval warfare 

and if lidar is used by satellites, aircraft and ships to track submarines 

then that could change warfare itself because of submarines' perceived role in nuclear deterrence 

lidar is a technology that uses lasers to determine distance
