It also has a far better radar, dual band. The CIWS is notorious for getting confused by the radar reflection off the sea surface.
Even a CIWS kill at close range (the only range it has) will leave a huge load of buckshot-like missile debris coming at you at rifle bullet velocity. Unlike WWII battelships and cruisers, modern ships are not armored to stop that.
Thats funny you say that, I would tow mothballed WWII craft along-side the carriers, fill them with sand, and then sail right up the straights... crude but effective. Hell a commandered oil tanker filled with sea water might do the trick.
