Re: Bismarck at DS after the second turn

I am gratified that the level of invective seems to have decreased in recent posts, and can only hope that the trend continues. I am also very encouraged to see Herr Nilsson's contributions as I have found his analyses to be consistently very thorough and responsible. I would suggest that in the fut...

Re: Bismarck's armor against long range hits

Some tradeoffs are involved. A deck made up of a single-thickness plate, though typically somewhat more efficient ballistically, if mounted 'high' protects the interior of the ship, but negatively affects stability. A single plate thickness mounted lower, improves stability but leaves the areas abov...

Re: Bismarck at DS after the second turn

I find statements such as: "Mr.Wadinga, finally and definitely defeated re.his crazy theory of Bismarck turn away before Hood explosion :shock: by all competent people writing here and shamefully unable to substantiate his NONSENSE, despite kindly requested by someone who apparently didn't know yet ...

Re: Bismarck's armor against long range hits

It's important to realize, I think, that the extent and thickness of deck armor had to consider the threats of both incoming gunfire and aircraft bombs as well. The optimum configuration -- assuming that there was some way to determine determine exactly what that might have been ante tempus -- would...

Re: 38 cm shells

This is really a repost of something I wrote several hours ago, which appears to have disappeared into cyber space. In the interim several other posters have submitted memos, but I have thought it still useful to re-post this one anyway. For typical big projectiles -- and again assuming reasonable c...

Re: Hits on PoW and Bismarck

In his post of Fri Nov 02, 2018 11:35 pm, Mr. Mercer made a request that further discussions in response to his initial question be terminated. Insofar as he began the thread, I will respect his (quite reasonable) request, and defer from further commentary. I might summarize before withdrawal. Witho...

Re: 38 cm shells

regarding 'light' vs 'heavy' shells and deck penetrations, as is usual It's very difficult to generalize. Really, each situation needs to be analysed on a case-by-case basis. There is certainly little-to-no justification to assume that lighter projectiles will in some way 'wobble' more as they trave...

Re: Hits on PoW and Bismarck

Before casting judgement, if indeed we can, let us wait until Wandinga has an opportunity to present his arguments and evidence, if indeed they are as you purport them to be. I don't mean to be argumentative, but I find your statement "PoW salvo plot irrefutable range closure proves that Bismarck ne...

Re: Hits on PoW and Bismarck

Bismarck's track charts of the Denmark Strait action have, of course, not survived. Nor has that of Hood. The Prinz Eugen and Prince of Wales have survived, and probably serve as the best overall references. In general, should discrepancies appear, it would seem reasonable to assume that the POW tra...

Mr. Virtuani wrote: "Another who can only petulantly and pompously try to teach good manners because simply unable to counter arguments."

Re: Bismarck construction flaws

At the risk of being picky, I might point out that the interpretation of the angle of fall in the previous diagram as about 19 degrees is incorrect, and represents an error very commonly made. When one is looking at transverse cross sections (I assume that it is indeed part of a transverse cross sec...

Re: Hits on PoW and Bismarck

My thanks to Herr Nilsson for posting the diagram, which helps to confirm my earlier presentation regarding shoring and flooding boundaries, etc. I was very impressed upon my visit to Bismarck, and my examination of subsequently obtained videotape of the Bismarck wreck with the elegant and well-thou...

Re: Hits on PoW and Bismarck

Regarding bulkhead construction, one would have to examine the ship's drawings to confirm thicknesses, etc. and admittedly I have not done this, although I have the data here to do so. That being said, in general, bulkheads, as might be expected, are designed to withstand hydrostatic pressure where ...

@ Byron Angel:

A close reading of the immediately previous memos on this thread will enable readers to determine from whence most of the animosity springs.
