...nasunął mi się pewien pomysł.
W ramach operacji stawiania min w lipcu 1941r, na Szweckich minach toną 3 niemieckie okręty, Tannenberg, Hansestadt Danzig i Preussen.
Pal, licho czy chodzi o błąd Szwedów lub Niemców, Ci drudzy żądają od Szwedów zadość uczynienia.
Szwedzi budują na bazie planów krążownika Gotland, kadłuby wraz z napędem, nadbudówkami, ale bez uzbrojenia 3 lub 4 jednostki...
...Niemcy korygują plany Gotlanda...
Poniżej wyliczenia z programu Springsharp. Dotyczą one zmodyfikowanego Gotlanda pod potrzeby Niemców i z ich uzbrojeniem. Planik w opracowaniu.
