Pancernik Kostenki - 12.06.2012

Dzisiejszy okręt to autentyczny rosyjski projekt pancernika dla floty czarnomorskiej autorstwa Władimira Kostenki z 1917 r. Projekt miał charakter pół-oficjalny, nie powstał bowiem na zamówienie floty, a z inicjatywy projektanta. Oczywiście w faktycznie zaistniałych w 1917 r. realiach nie miał on najmniejszych szans na realizacje, niemniej wydaje się być całkiem ciekawą propozycją.
