So, for the AAA BB, I've checked and we should be able to get a design that isn't quite what was requested but may be a touch more practical. We'd need to be buying from the Americans to get their more advanced AAA outfitting, but this anti-air focused cruiser would provide about 90% of the firepower that such a battleship would bring. It combines a main battery of dual purpose 6" guns with the maximum amount of DP 5" guns as well.
