The report interestingly makes a comparison to cruise lines and the US Navy having large IT infrastructures at sea. I guess cruise ships of course have servers plus satcomms, as do warships. But the thought of the SOSUS sonar chain comes to mind... then again those electronics will be down a lot deeper than this. Though I am sure a few racks of FPGAs near your SOSUS listening devices would be good...
