Drugi alternatywny niemiecki Gangut

 Dziś drugi wariant pancernika rosyjskiego ze stoczni Blohm und Voss, o nr 627F. W zakresie „papierowych” charakterystyk jest niemal dokładnym powtórzeniem poprzedniego projektu nr 627D i różni się od niego tylko wypornością mniejszą o nieco ponad 100 ton. Istotne zmiany zaszły natomiast w wewnętrznym podziale kadłuba, gdyż zamiast układu KKMKK (maszynownia między kotłowniami) zastosowano KKKKM (maszynownia za kotłowniami). Te zmiany w widoku zewnętrznym przekładają się na sylwetkę – inna jest lokalizacja dwóch wież na śródokręciu oraz kominów. Zdaję sobie sprawę, że pewnie entuzjazmu nie wzbudzi, ale skoro już go narysowałem, to pokażę.
