sama cytadela - chroniona pasem pancernym 320mm + znajdujacym sie za nim skosem pancernym (pod katem 22-23') o grubosci 110-120mm + znajdujaca sie za skosem 45mm pionowa grodz wzdluzna - byla raczej nie do ruszenia...
ekwiwalent pancerza grubosci 650 milimetrów, ej adminek przesadzasz
nikt w historii nie miał takiego zabezpieczenia
jeden facet, niejaki Nathan Okun (taki amerykanski specjalista od pancerzy) nawet to policzyl...
oto jego opinia:
I plotted the striking velocity needed for complete penetration of a 4.33" Wh plate (assumed to be similar to U.S. Navy WWII STS plates against which my test data was compiled) versus obliquity from 45o to 68o. On the same graph I then used my face-hardened armor penetration computer program to plot the remaining velocity and the impact obliquity on the 4.33" plate - which equals the 68o backward plate slope minus the projectile's downward exit angle after penetrating the side armor - for the 38 cm projectile after it hits the 12.6" belt (plus backing) at a Target Angle of 90o (only angle of fall affects obliquity). The two curves gradually converged but never met, indicating that the sloped deck was impenetrable to the German 38 cm projectile at all ranges, as designed.
Similar computations with British 14-16" projectiles concerning hitting the sloped 4.33" deck after going through the 12.6" belt gave identical results. Even the 18.1" (46 cm) guns on the IJN YAMATO would have had to be placed directly against the side armor of the BISMARCK to have even a chance of penetrating that sloped deck. The German designers had done a very good job in this one protection area!
....
My computations also indicate that, as expected, the 3.15-3.74" horizontal portions of the lower armored deck could not be penetrated under any conditions after penetrating the 12.6" side belt by any projectile used on any actual warship.
konkluzja, w mniej barbarzynskim jezyku jest nastepujaca:
nie istnial taki pocisk, na zadnym okrecie
ktory moglby po przejsciu przez pancerz burtowy 320mm (plus podklad)
pokonac dodatkowo ten 110-120mm skosny pancerz Bismarcka... under any conditions
nicpon
... przynajmniej do odległości dwudziestu kilku tysięcy metrów - maksymalnej odległości ówczesnych bitew... oczywiście dokładne IZ zalezy od pocisków...
