Re: USS Arizona vs. Bizmark

Re: Iowa Class real performance

Re: USS Arizona vs. Bizmark

both barbettes were expected to be penetrated at distances less than 24.000 yards (Bis slightly better) on turret fronts roughly draw at 19.000 yards. The SK 38 is able to penetrate roughly 2" more armor at distances around 20.000 yards than the US 14" Gun and the KC/na steel is aproximatly 4%-5% be...

Re: Range and Penetration Table for the 38 cm SK C/34

Its a simple analysis from the fall of striking velocity between every km to the next km, because of drag from the "Range and Penetration Table for the 38 cm SK C/34 Guns" statet here http://www.kbismarck.com/38cm.html in the attachment you can find data, chart and also the labels the fall should be...

Re: Range and Penetration Table for the 38 cm SK C/34

appended a Table with the Fall of Speed
The problems of difference I meant were on kilometres 4, 10, 13, 14, 20, 22 km

this sequence is also expected to be smoth in general

If you create a similar sequence from the pentration data you can see the same problem

Re: Range and Penetration Table for the 38 cm SK C/34

It seems there are some misreadings from the chart entered into the penetration table Unbenannt.JPG attached you can see a samplechart with differences from every kilometer to the next "Striking velocity" this chart should bee smoth, but there are some "edges" so you could check and maybe correct if...

Re: Danger space, hitting space

Bismarcks mgazines were not accessible by hits below the main belt
Only through the main belt and / or through the decks
