I am not sold on the continued use of both 5" and 3" secondary mounts. I personally would probably move to just 5" mounts to compliment the 10" primaries.
I putted in the 3" as a Heavy AA but I shall change it. For when I think a bit, the Sea sparrow and the CIWS that are not mounted on this drawing will do all the AA work, together with other ship.
BTW where would you put those two CIWS, and do we have some Never where CIWS I can use?
