Autonomous low-profile logistics vessel will transport 18,000 pounds of cargo over 2,000 nautical miles without a crew, supporting long-range maritime resupply missions. The vessel must be able to sail on its own for over four days, while still allowing human operators to take control remotely during critical moments such as port departure and approach. Ha - drug runners probably been using such vehicles for years - including similiar concept micro subs ?
