if it is post treaty then isn't it better to have 1 more BB than 2 heavy cruisers? The relative cost works out about the same. Anyway if money is no object then why not build 25,000-30,000t BCs such as dunkerque.
Have a read about the British admiral class; these were post treaty cruisers with old 9.2" guns and were about 25,000t. They were abandoned for mainly 2 reasons; might as well have another Vanguard rather than 2 cruisers. And that there were no other ships like them. They could only engage ships as good or worse than themselves. i.e. not BBs or BCs.

Sorry but i just feel that ultra cruisers are worthless. apart from a flawed concept, shes OK.

90% arour? does not protect all? you sure?

2 superfiring turrets? how?

cheers

I personally would stick with an armament of 8.2" guns for my cruisers and make the jump to 12" for alaska type ships.
