"Imagine what the Jersey could do today with precision guided munitions!"

Actually, even in the 80's when Reagan took the Iowa class battleships out of mothballs they were outdated. The reason the Navy brought them back had more to do with prestige than actual Naval necessity. By the end of WWII, the age of the battleship was clearly over.

The big guns - yes. But they were also retofitted as cruise missile launch platforms - their new big guns and lots of them IIRC.
