Give a single Iowa class battleship the same tech, and it'll be worth twenty of our modern "cruisers." A fancy targeting system won't do you any good when your 5 inch shell bounces off of several feet of steel. Give a fancy targeting system to a ship with 9 16 inch cannons and who-knows-how-many 5 inch guns, though, and you've got a ship that can take on a fleet. Factor in the sheer number of anti-aircraft and anti-missile systems a ship that big could hold, and it'd be darn near untouchable. Seriously, we're capable of building far better ships than we are now. Missiles can be shot down, a constant barrage of shells can't.
Nope But don't want to derail this thread. If you want to open a thread I'll tell you why your not right.
