Sorry but once the location of a capital ship is defined, but a flock of drones, each the size of a seagull packed with C4 plastique launched by a distant submarine and directed by satellite, will destroy virtually any capital ship. The technology already exists.
So the seagull drones will fly into the ship and the C4 exploded? The drones will do 35+ kts? Explosives expert as well I see.
Name the weapon system.
And, assuming it doesn't exist, why do you think that is...since it's so simple?
