Krążownik pancerny Northampton (1936) - 21.04.2011

Dzisiaj prezentuję zasymulowany w springsharpie okręt mogący być brytyjską odpowiedzią na niemieckie pancerniki kieszonkowe. Pomysł tej jednostki przedstawił Blenheim na forum DWS, on też jest autorem grafiki którą możecie zobaczyć poniżej:-) Ogólne dane okrętu miały się przedstawiać następująco: 20.000 ton standard, 31-32 w., 10x234, 8x120 plot. i 8 wt 533 mm. Oczekiwany pancerz miał być na poziomie 102 mm burta i 76 mm pokład. Okazało się, że przy takiej wyporności udało się dać dużo grubszy pancerz: 203 mm na burcie i 102 mm na pokładzie. Takiego przeciwnika pancerniki kieszonkowe musiały by się mocno obawiać, zwłaszcza że uciec przed nim by nie dały rady, a same na ogień jego artylerii nie były by odporne..
