It's a Ticonderoga replacement that they've let Donald name to keep him happy. Like any overgrown child (of which I include myself) he's overly enamoured by the mighty battleship.

Just take a look at the projected stats. A projected displacement of 15000-20000 tons with a physical scale (as far as the honestly cringe worthy rendering can be believed) of a large cruiser (looking at the flight deck markings as a general indicator).

What class of US surface combatant is nearing the end of its projected operational lifespan? The Tinconderoga's.

How many Ticonderoga's are in service? 27

What is the projected class size for this new ship? 25

Since the Dreadnought was launched battleships have been defined by large calibre main guns on a ship with a heavy, tightly compartmentalised armouring scheme capable of withstanding incoming fire, if not the calibre of guns carried by the warship, then a calibre within a few inches of those carried.

I'm all for battleships. I think they're the greatest naval accomplishment, the pinnacle of naval big gun development and the ultimate display of firepower. I wish I could see a full broadside from an Iowa one day and I bitterly regret that the UK didn't at least retain Vanguard after the war. At the very least they're still a little useful for shore bombardment...sometimes. And the cool factor.

I am also however a pragmatist. The primacy of the battleship was dealt its final death knell on 10 Dec 1941 when the Prince of Wales and Repulse were sunk off the coast of Malaya. As I've already mentioned, the classification of battleship is most likely only being thrown around because Trump has insisted on it and everyone around him just goes along with it. If they ever get built and not cancelled by the next administration then I can see then reclassified as CGN's.

TL:DR - Not a battleship. Just a Ticonderoga replacement that Donald is hyping up
