if 9 turrets will fit?? why not 12 - how about on the wings too

4 pyramids of 3 twins - fore, aft and each side - perfect symmetry ;D - and 24 main guns !!!

guess would have to be smaller calibre on just 720' - and quite wide beam - but early German BBs had 2 wing turrets each side - 13" calibre possible?
