Łącznie stworzono siedem różnych wariantów okrętu – ja dziś prezentuję wariant IV-2 który wydaje się być najlepszą propozycją – uzbrojenie w 15 dział 457 mm wydaje się być optymalne, choć intrygująco przedstawia się wariant z 24 działami 406 mm w sześciodziałowych (!) wieżach. Jest na tyle ciekawy że pewnie też go kiedyś zasymuluję, choć sama konstrukcja i użyteczność wież mających po 6 dział wydaje się dość problematyczna..
