All of the Ladies you mention, have had their teeth pulled, and are now enjoying retirement in some back water, some where, I remember standing by the spot of the Missouri where the Japanese had signed the peace treaty.Those days of when we protected our interests are long gone.
I believe congress mandated that they be keep in fighting condition, just in case. Nothing impresses as much as an Iowa class battleship cruising a few miles offshore. Not even an aircraft carrier impresses like an old WW2 battleship. Sure wish we had a new one with modern 16 inch guns. Bet new guns could get twice the range of the WW2 guns maybe even longer. I have read that close to 100 miles is possible for a big modern gun. Oh and the HE round is 2,000 lbs, makes a very big bang when it goes off. The AP round can penetrate 160 feet of reenforced packed earth. Forgotten the penetration on concrete but it was impressive too.
