I was not aware that no one had battleships anymore! maybe I am just using the wrong word? a ship with giant guns that can rain hell down upon a coastline in prep for an amphibious assault.
USS Missouri BB63 was the last battleship to be in commission in any of the world’s navies; she was decommissioned in 1992. Nobody has big gun ships any more. Big gun cruisers are also a thing of the past; destroyers and cruisers are all missile platforms, now, with a 5” rapid-fire gun or two because sometimes you need a gun.
We have the 4 Missouri class ships (our last and best) in mothballs/museum status. The were initially decommissioned in the ‘50s, with the NJ (at least) brought back for Vietnam. At least 3 were brought back under Reagan, and one or two shelled the ever-living crap out of our Arab enemy of the day in Lebanon in the mid-’80s. One shell allegedly killed 30 Syrian generals in an “unpenetrable” bunker.
They could be brought back, but it would be expensive to do so, they would absorb a LOT of manpower to run, and they’re too slow to keep up with the carriers. They also burn oil, and are huge sitting ducks for missiles.
No one else has had a battleship for at least 60-70 years.
