Krążownik pancerny i torpedowiec dla Japonii - poprawione - 01.10.2011

Dwa okręty z wczoraj były do poprawki – zatem dziś ich ulepszone wersje;-) Co do torpedowca – poprawa jest, ale nie wielka, prędkość jakkolwiek nieco wzrosła, pozostaje na poziomie jednostek tej klasy w innych flotach w tym czasie. Wygląda na to, że bez istotnego zwiększenia rozmiarów nie uda się skonstruować wyraźnie lepszej jednostki.

Krążownik pancerny postanowiłem zmodyfikować w ten sposób, że przy pewnym zwiększeniu jego wymiarów zmieniłem radykalnie uzbrojenie – na mniej liczne, ale za to o większym kalibrze, w dodatku umieszczone w barbetach, a nie w nieperspektywicznych kazamatach, co dało lepsze pola ostrzału dla poszczególnych dział. Natomiast co do prędkości – tu także poprawa nie jest specjalnie znacząca, i następny typ będzie musiał być również znacząco większy.
