Dzisiaj
kolejna porcja okrętów dla Japonii:-) Po pierwsze –opancerzona korweta.
Ponieważ wszystkie dotychczasowe krążowniki (ściślej rzecz ujmując –
drewniane fregaty i korwety) były nieopancerzone, nową jakość i przewagę
nad potencjalnym przeciwnikiem postanowiłem osiągnąć poprzez lekkie
opancerzenie nowego typu korwet. Drugim typem okrętu jest kazamatowy
krążownik pancerny (albo jak kto woli – pancernik II klasy), okręt w
zamyśle mający współdziałać na polu bitwy z flotą liniową i być jej
szybkim skrzydłem. I wreszcie trzecia jednostka – zupełne novum, czyli
torpedowiec. Niestety dwa ostatnie typy nie są zbyt udane - brakuje im
m.in. prędkości, ale zamierzam je w przyszłości ulepszyć;-)
