I just love the "relatively easily be converted to drop buoys" bit. On top of the bit by Phoney T, can you tell me how you are going to select the channel required, select the cable length, select the life of the buoy? All of these need to be done manually so you will have to redesign all of your buoys so that it can be done automatically. And then I return you to your UOR RPAS for which no-one has yet designed a sonobuoy carriage system, release system and monitoring/retransmission system.
