From a timely cyberwarfare reality check

""Annapolis and its sisters are the infiltrators of the new new of cyber warfare," wrote Arkin and Weinstein, "getting close to whatever enemy — inside their defensive zones — to jam and emit and spoof and hack. They do this through mast-mounted antennas and collection systems atop the conning tower, some of them one-of-a-kind devices made for hard to reach or specific targets, all of them black boxes of future war."

But even this doesn't compare to what the Navy wants to be able to do next: turn its submarines into motherships for underwater drones that can maneuver themselves even closer to shore and conduct jamming or hacking operations while allowing the sub to work at a distance."
