Japoński krążownik ciężki 12x203 - wersja czterowieżowa

Oto modyfikacja projektu z poprzedniego posta. Artyleria tym razem została zgrupowana w czterech wieżach trójdziałowych, a zaoszczędzone w ten sposób miejsce i wyporność spożytkowano na montaż dodatkowych dział 100 mm  w liczbie 8, tak że ich sumaryczna liczba wynosi teraz 16.
