Yes but you have to account for the barely-functioning melted brain factor. Reality just can't compete when an old man goes "pew pew! zoom!"

Yes-ish. In a serious fight against a peer-ish level adversary, the RoI on such a ship looks very dubious.

But short of that, a huge warship can have great prestige & intimidation value - assuming that it is competently designed, and built, and outfitted, and operated. Naval history is swarming with only-on-paper designs for big warships. And a fair number of real-steel warships which were cripples, glass cannons, or sitting ducks because of incompetence somewhere in that chain.

(Also, the USN is referring to it as a BBG, not BB - https://www.navy.mil/Press-Office/Press-Releases/display-pre... )

If you mean in terms of armament, this ship would have more missiles than any other class in the US fleet by a wide margin.

If you mean as a threat, the USN has ships sitting in the Red Sea as the Houthis and Iranians and whoever else sends off drones and missiles and they've all been fine.

Relevance is obviously not the Fuhrer's concern.

I mean, this isn’t going to actually happen. It’s just ego-stroking for mad king Donald.

But yep. Really they died before that; the last battleship ever built was competed in 1946, and scrapped in 1960. It was aircraft carriers that killed them off, really, not missiles and drones.
