the USS New Jersey battle ship.

Unless your enemy has no air force, battleships are nothing but floating targets. There simply aren't enough land-based enemy targets within range of the shore, and any major naval opponent has aircraft carriers.

That said, I certainly wish we still had stuff like that.
There's a great online article that's not hard to find that in one paragraph basically says that, but in the next, tells how useful they could be if upgraded to the next level of rail gun technology and how easy it would be to do to those big guns. With all of the money this country sends to pukes who hate us, it would be easy to come up with funding by eliminating that nonsense.
