HMS Untakeable II - 04.06.2012

A oto druga wersja fisherowskiego Untakeable'a - tym razem uzbrojona w ujednoliconą artylerię, na którą składa się 16 dział 254 mm, z czego 10 może strzelać na jedną burtę. Do obrony przed torpedowcami okręt ma 16 dział 102 mm w kazamatach, co również stanowi postęp w stosunku do poprzedniej wersji wyposażonej w działa 76 mm. Dwie poniższe grafiki pochodzą ze strony www.http://dreadnought-cruisers.blogspot.com - minimalnie je zmodyfikowałem, bo nie wydaje mi się, by dla takiego okrętu w początkach XX w. stosowano dziób kliprowy - zastąpiłem go stewą dziobową analogiczną do ówcześnie stosowanej na większości dużych okrętów pancernych.
