Thank you Carthaginian. You actually seems to be the only one so far who has picked up on the significant calibre increase on the Thevais compared to 'normal' heavy cruisers, either Treaty or London-cruisers.
In the N-verse, I used 9.2" guns for my 'heavy' cruisers; people will be surprised how fast the seemingly small caliber increase adds up in the weight of broadside. A 9.2" gun firing a 'superheavy' 400 pound shell would be a truly devastating weapon for a nation not planning to field a true 'battleship,' but interested in taking down treaty-compliant heavy cruisers.
