Why Vanguard is the most adaptable 1945 capital ship

Which Royal Navy class sailing in 1945 would be most useful if restored for service in 2023?

Vanguard, if restored as new, because her size, stability, guns, and upgrade margin offer more useful options than smaller ships.

Most 1945 escorts are too small for easy modernization, while contemporary carriers need major flight-deck work to operate F-35s. Vanguard has margin for modern sensors and missiles, and her 15-inch guns could provide shore fire if their operation were automated.
