My design for a 1950 Dutch battlecruiser: the Wapen van Zeeland

I would build this class of four Dutch battlecruisers that are trying tohave a more modern outlook on fast capital ship design: the Wapen van Zeeland, Gouden Leeuw, Eendracht, and Nassau. I call the design the NL/CB/1950. The ships would obviously need operate under air cover, but could deliver shore bombardments and back lesser ships in blockades. This is the Springsharp report:
