Korweta parowo-żaglowa (1877)

No, teraz to mnie chyba rozstrzelacie, ale trudno – narysowałem, to trzeba zaprezentować;-) Poniższy okręt to korweta parowo-żaglowa, odpowiedź na niemieckie korwety typu Leipzig i Bismarck, wodowane w latach 1875-1879. Na tym przykładzie widać niestety, że flota niemiecka zaczyna nam ilościowo odjeżdżać – bo naszych jednostek są tylko dwie, a ich – w sumie aż osiem (sześć typu Bismarck po ok. 3000 ton i dwie jeszcze większe korwety typu Leipzig po 4500 ton). Pozostając jednak jako tako wiernym realiom, nie mogę niestety zignorować faktu potęgi ekonomicznej Rzeszy w tym czasie i naszej relatywnej mizerii względem niej. No chyba, że bardzo będziecie chcieli, to dobuduję jeszcze tych korwet:-P
