Re: Bismarck/Tirpitz = most powerfull European battleships

The document cited by Thorsten says that the increase in protection is about 30-50% when the shell breaks up and 10-20 % if it is decapped and/or yawed. This document also says that yaw can improve penetration but maybe they are referring to the shell being deflected to the normal. http://www.kbisma...

Re: Bismarck/Tirpitz = most powerfull European battleships

Thanks for the summary, Thorsten. So what we have is, that if the projectile breaks up, the spaced array can be 30-50% more effective, which is not going to happen with the 50mm Oberdeck. If the projectile gets decapped (which it does) and yawed correctly, spaced arrays can be 10-20% more effective ...

Re: Gun-loading question

All 4 French post treaty ships had any angle loading but suffered from jams at higher angles and usually loaded at 15°. They were full of innovations but also seemed to be a bit too much ahead with their wishes resulting in problems/failures (their RPC which was only fitted in R and JB after problem...

Re: Bismarck/Tirpitz = most powerfull European battleships

One notes that the body of mostly secondary and beyond secondary based sources that have established the conventional wisdom concerning the Bismarck's design, and particularly the armour scheme, are vaugely cited, if cited at all. Most people here know what is written by Okun on navweaps and this c...

Re: Bismarck/Tirpitz = most powerfull European battleships

So if a spaced array is superiour and if the superheavies were especially prone to fail against such a design I would like to se the relevant documents to back up these theories which should be very easy to provide for someone who has them on his computer. Such categoric statements can not be suppo...

Re: Bismarck/Tirpitz = most powerfull European battleships

[ What is the source of your argument, that the striking angle was not 33°? Besides it is not the only angle given at over 30°. a) Absence of evidence of a 8* list by the bow b) The probable distance Massachussets was firing from (20-22km), corresponding to an angle of fall of 24-25*. c) the drawin...

Re: Bismarck/Tirpitz = most powerfull European battleships

I "got it" from several debates with members of the forum who have access to much more primary documents than I have. One of those documents depicts the re-construction of Tirpitz in 1945-1946, in order to test the effects of heavy shell fire (14", 15" and 16") against the German turtle-deck design...

Re: Bismarck/Tirpitz = most powerfull European battleships

Do you base that on what delcyros wrote on navweaps (which is only his opinion)? It was some time ago I looked into Jordan/Dumas but Richard Worth came to the same conclusion. Who is Delycros ? The problems of the French armor are documented. I only know about: - the testimony of a German engineer,...

Re: Bismarck/Tirpitz = most powerfull European battleships

According to Jordan and Dumas the hit that penetrated the magazine hit at 33° according to damage analysis. JB received flooding through bombs prior to the hit and the resulting list seems to be the cause for such an angle rather than the extreme range needed. The angle was not measured, but it was...

Re: BISMARCK armor scheme = BADEN?

Although I'm loath to post here I will do so, since I met Thorsten some weeks ago and he shared some insight with me. Lets be clear, I speak for me, not for him. The admirality documents do not show, as far as I have seen them, that a spaced array is better that an aon scheme. They do show that it c...

Re: Preston: Worst warships of all time

You seem too imply that BS and VV were not considered then G&D say that the SoDak`s were the best treaty ships. That is not the case. The limit was simply ignored by the Italiens and Germans but they were still officially treaty ships and are therefore part of the comparison.

Re: Preston: Worst warships of all time

How about degrading Yamato and Musashi due to Shinano`s horrible damage control? Or is this case of an completely untrained crew (and still incomplete watertight integrity) not comparable to a green crew and an electrical problem as far as criticising the entire class is concerned? Both problems wer...
