So the NelRod armor design evolved around this projectile behavior with some margin.

End of thirties shells were better.

Re: (No) Fuelling about in Grimstadfjord?

I suspect Bismarck was filled up to the top in the beginning including reserve fuel/trim tanks in the bow(Öl- Sonderzuladung 1000/2000 t.) This "additional" fuel oil could be used up first.

Re: Bismarck final battle and German main battery accuracy Qs.

In the final action Bismarck's fire-control would have to initially compensate for the list and then for the erratic motion of a slow moving vessel more at the mercy of wave action than a fast moving one, and finally for the continual turning imposed by the jammed rudder. without firecontrol ist al...

Re: Admiral Hipper class vs contemporaries

Actually, I have done more research and I believe that I was actually accurate in my original post. The Wichita did use the 335 lb AP shell.
According to Navweaps
Wichita used the 260 lb AP-shell.

Re: Was the battleship Bismarck really the best of its time?

Whatever the validity of the claims by ships' AA, some of the Swordfish were destroyed or damaged by JG 26 Fw 190 fighters which had to attack from astern, and lower their landing gear in order to fly slow enough to "draw a bead". Scharnhorst was also attacked by Swordfishes in this case 1 aircraft...
