Dziś dwa kolejne pancerniki dla floty japońskiej, oparte o francuski projekt, kończące ten mini-cykl japoński. Tym razem podstawą jest jeden z wstępnych projektów pancernika Charles Martel z 1890 r., autorstwa inż. Ernesta Huina (autora Hoche’a, co jak mniemam, jest wyczuwalne w sylwetce;)) Jest to już jednak okręt kolejnej generacji, z opancerzeniem ze stali niklowej oraz – przede wszystkim – z długolufowymi działami na proch bezdymny. Okręt ma wyporność 11600 ton, rozwija 17 w. i jest uzbrojony 2 działa 305 mm L/45 i 2 – 274 mm L/45, 8 szybkostrzelnych kal. 138 m (wszystkie w wieżach), a do tego lekkie działka przeciw torpedowcom.
W ten oto sposób, u progu wojny z Chinami, flota japońska dysponowałaby niebagatelną siłą aż 8 nowoczesnych pancerników. Może więc trzeba by jeszcze pomyśleć o uzupełnieniu ich odpowiednimi siłami krążowniczymi? Realnie, Japończycy mieli w latach 80-tych tylko 2 okręty typu Naniwa (nieszczęsnego Unebi trudno liczyć), więc jest tu pole do zagospodarowania ;)
