Lightly armed? I don´t think so. Especially his light AA guns. Just look at the numbers. He simply doubled what I put on the Quiz-cruiser. Now, honestly, do you think there is enough deckspace for all those guns? Look at my drawing and tell me, where to put all those guns.

But ehy, he doesn´t have to care about that very long. The first time his ships are at sea, they´ll snap in two. Their beam to length ratio is far beyond realismn.

Sorry for nitpicking but a block coefficient of slightly over 0.4 is hardly realistic for a cruiser - except for a over-sized DD like the french MOgadors or a mini-cruiser like the dutch Tromp or italian Condottieri Typ A but even then, Tromp for example has a bc well in exess of 0.4....

Is there a reason why you want to build Southamptons (once I´ve mentioned them)?!

And: All of those designs, realistic or not, belong into category a) and you don´t have enough tonnage for many cruisers of that category. I wonder if you´ll build single ship classes only?
