This can hardly be called a cruiser I think. It´s an old-fashioned BC I think - fast, decent armament for its size but weak armor - relatively speaking.

Given that she is 1500ts larger than a DUNKERQUE and the latter is heavier armed and better protected I question the value of your design. Sure, she damn fast but a single shell or torpedo can ruin her day by slowing her down...and planes she´ll never outpace of course. Sure, you´ve a really heavy DP- and AA-armament and close to all good comments available in spring* what sounds impressive but you achieved this by using a overly (overgrown?) large hull and a very low bc given the ships overall size and tonnage. This is an old problem with spring*: a large hull combined with a low bc allows unrealistic good designs on relatively small displacements.

Why too short a belt?
I also wonder what those 1000ts misc weight are for? I guess to compensate the additional weight of the diesels used?

However, it is an interesting design and a real cruiser-killer. No CA or CL could hope to stand a chance.

Keep ´em coming,

well, if ever built she would not try and shoot it out with a BB, that'd be suicidal. and yes I know she is a fisherite BC.
the weight is there to compensate for diesel and electrics ...

as I said unlikely ever to happen, but a certain entertainment value ....
