Interesting take from Ryan Szymanski. One of the big items is the sustainment in both strike and defense that a big ship can provide while smaller ships run out of missiles and/or fuel and must retire from the area, although perhaps the reload capability of VLS cells at sea will become normalized and alleviate that concern.
As Spekkio mentioned above, and I wondered about a decade ago in Ship Photo of the Day, would we see a return to non-aircraft carrier capital ships when technology improved? The carrier replaced the battleship 85 years ago when airplanes could outrange guns - have/will we reached the stage where hypersonic missiles and cruise missiles turn the table? And if not this “battleship”, is there a place for a 20,000 - 25,000 ton large cruiser?
