Niemiecki rajder Beowulf - 05.01.2012

Dzisiaj proponuję coś niestandardowego – niemiecki projekt P,czyli wielki krążownik (jak kto woli – krążownik liniowy) przeznaczony do operacji korsarskich na liniach komunikacyjnych wroga.  Jest to swego rodzaju nowocześniejsze wydanie wcześniejszych „pancerników kieszonkowych” (napęd stanowią oczywiście diesle) .Z powodu wybuchu wojny nie zdążono takiej jednostki oczywiście zbudować (pomysł był dość późny, bo dopiero z 1937 r.), zresztą sam projekt rychło wyewoluował w kierunku znacznie potężniejszego okrętu (projekt OPQ - 6 dział 380 mm w trzech wieżach + 6 dział 150 mm i wyporność ponad 30000 ton), o którego przedstawienie być może pokuszę się w przyszłości;-) Poniższe zdjęcia modelu (jak i sam model) wykonane zostały przez Jefgte z forum Warship Projects Discussion Boards.
