What kind of ship would they want to call a battle cruiser? Surely no one is thinking of a ship sporting 18 inch guns.

In my opinion it’s just a matter of time before they teach large drones to land on very small carriers. Once that happens every ship in the current navy will be obsolete. We are fast approaching a Dreadnought moment.

. . . very small carriers.

Which work just fine in calm seas. But if the sea starts to pick up, the deck gets to moving so much that nothing can land on it. A significant reason US CVs are so big is so they can operate in (nearly) any weather.

And then there is the fact there is a large infrastructure (repair shops, etc.) that can be spread among a larger airwing on a bigger ship. The planes per dollar numbers for small carriers are terrible - and they still can't operate except in good weather.

'Sounds too much like an "assault cruiser".
