Something new...
I was never particularly happy with the Type 45 solution as a 'command' cruiser, the VLS arrangement was dubious and it lacked other features I wanted to include and, after a few false starts this is the result.
Essentially (at least aesthetically speaking) it's an amalgam of the Atago and Sejong the Great classes slightly scaled up albeit with some notable changes here and there.
