Francuski pancernik traktatowy - 13.04.2010

Traktat waszyngtoński zawierał klauzulę zezwalającą Francji rozpoczęcie w 1927 r. budowy nowego pancernika,oczywiście w granicach 35.000 ton wyporności i z artylerią maksymalnie 406 mm. Moja propozycja idzie w kierunku obniżonego kalibru artylerii głównej (16 cali nie jest dla mnie żadnym fetyszem;-)), za to solidniejszego opancerzenia. Wyszło coś takiego:
