De Ruyter z 8-calówkami - 25.10.2010

Alternatywna wersja krążownika De Ruyter mojego pomysłu - uzbrojona w 4 pojedyncze działa 203 mm zamiast 7 dział 150 mm. Trochę taka poczwarka na wzór krążownika Krasnyj Kawkaz:-) W sumie siła ognia jest nieco większa niż w przypadku wersji z działami 150 mm, ale na japońskie jednostki to i tak o wiele za mało..
