I think for it to be more realistic it should have been that the CIWS was down so it just sat there like a big white trash can and was immolated by an ASCM.Actually I remember one of the Phalanxs on the Nimitz not being able to decide which of the two inbound ASCM's to shoot down, then not firing at either, of being a somewhat realistic portrayal of how a weapon system could fail for a simple reason (not knowing anything about the Phalanx itself).
