Orange mini Battleship design competition

[Walter]

Main belt does not fully cover magazines and engineering spaces

[Nobody]

*grrr* when did that happen?  :-[
Problem solved, thanks. It was just 8 cm though, luckily elongating them was well within design reserve 8)
Anything else? What about the misc (esp. the last two points on that list)?

[Guinness]

Both items are strictly designer's choice. 135 tons is a lot more than the CSA allocates to command facilities, but fits with some other nations, I expect. Generally, many of us use a figure of 400t total for misc weight for a capital ship, give or take. This would include 250t for FC, 25t for a long range wireless set, and 175t for "other stuff".

[Sachmle]

IIRC the Jap thick plate was a laminate, not a single sheet. Thick, but weaker. Also, you could try "French" layout for the MB turrets. Would shorten your citadel and probably save weight, however it will make her less steady/stable. OTOH, the BB design that P3D finished last was 29.5k, ~29kts, 13" belt, and had 3x3x13.5" guns. It's in here

here is my attempt hopefuly i am not to late? but here it is any way

I don't think Quad 16s give much actual space for Torp Protn system abreast the Main turrets with 98' beam - how about broader beam and shallower draught?

[sgdn]

here is version 2 there are some other changes as well those the the beam and draught
