>>977936>a nuclear submarine could drill and mine better than a surface ship. Not a chance. Undersea drilling and mining requires tons of equipment and large platforms to be cost effective. The beauty in pic related in Maersk Interceptor. She can drill 150 m depth year round in the harshest parts on the north sea. She also cost about $650 which is at or below unit cost on modern nuclear attack subs. Trying to sink things underwater, and make them work, is much more challenging and provides very few advantages over just letting them float.
