Giving an armed uncrewed submarine broad autonomy trades a communications problem for a command and control problem. The vehicle would need enough computing power to interpret a complex underwater environment, which raises demands for electrical power, cooling, and quiet operation. Low-frequency links cannot support continuous supervision or a last-second human decision during an attack. Transmitting in the run-up to an engagement may also reveal the vehicle's position. The system could therefore make a lethal decision without a reliable remote kill switch. There is disagreement over the severity of the cooling problem: one panellist considers heat less troublesome because the submarine is surrounded by cold water, while others stress the cost of operating powerful computers quietly in a compact hull. Electrical demand remains a concern alongside the lack of dependable human supervision.

The command problem with autonomous armed UUVs
An armed autonomous UUV may have to make lethal decisions beyond reliable communications, while carrying costly computing, power, and cooling systems.
