Alternatywny Bismarck - 08.05.2011

Co by było gdyby Niemcy zdecydowali się jednak trzymać limitów traktatowych przy budowie swoich nowych pancerników? Pierwsze przymiarki do Bismarcka zakładały okręt mieszczący się w dozwolonym traktatem waszyngtońskim limicie 35000 ton wyporności standard, uzbrojony w 8 dział nietypowego kal. 330 mm,do tego artylerię średnią i plot. Składającą się z 12 dział 150 mm i 16 dział 105 mm, oraz mający pancerz boczny 350 mm i na pokładzie 100 mm.Uznano jednak, że nie dało by się takich parametrów osiągnąć w zakładanej wyporności, skutkiem czego pomysł ten porzucono, na rzecz znacznie większej jednostki. Springsharp jednak zdaje się sugerować, że pomysł był do zrealizowania?
