Re: Bismarck's port rudder

Are you sure about those pumping figures? They seem awfully high to me.

Re: Bismarck's port rudder

Thank you, Marc and George, for some very helpful and constructive comments. The confusion in translation can be a real problem, and is one reason why I always try to get German-speaking authors, etc. to write on German ships. Reading documents only in translation can be dangerous and misleading. I ...

Re: Bismarck's port rudder

Hello George: Thanks for posting this. It's not uncommon when visiting wrecks to find numerous instances where the testimony of survivors just couldn't possibly be true, which over the years generated the well-known forensics phrase "...the steel doesn't lie." This does not, of course, suggest that ...

Re: Bismarck's port rudder

To 30knots: I am not sure exactly what your sources are, but regarding damage to the propellers and rudders, etc., one must remember that most of the accounts now generally available were written well prior to the detailed examination of the wreck itself. Further, many are inherently ambiguous, eith...

Re: Salvo Patterns - USS North Carolina WW2

Yes. The standard 'Rule of Thumb' for the 16" batteries was that a nine-gun pattern would be about 1.9% of range.

Re: Bismarck's port rudder

I think we were all a bit surprised to see that configuration, i.e. with the rudder post broken off and the collar etc. and the plating alongside not even significantly deformed. It's clear the rudder wasn't CUT off, insofar as the broken edge is inside the hole a bit. On the other hand, it appears ...

Re: Bismarck's port rudder

Basically, no.

Certainly nothing significant.

Re: Bismarck's port rudder

The nature of torpedo hits is such that they rarely, if ever, disclose the obliquity of the initial impact (unless they are 'duds'). Excepting a small angle which would be masked by the position of the port rudder, the torpedo that hit the starboard rudder could have come from anywhere. Although the...

Re: Bismarck's port rudder

Indeed, the rudders were aligned roughly parallel to one another as the ship was turning. But that does not mean they saw the explosion in the same way. If you draw two parallel lines and create an explosion somewhere along one of them, the rest of that particular line will see the explosion 'end on...

Re: Bismarck's port rudder

Yes. My observations suggest that the torpedo actually struck -- or exploded very near to -- the starboard rudder. Probably, the starboard rudder was not detached because it was essentially 'end-on' to the shock wave, i.e. had a knife-edge pointed towards the explosion. It ended up getting pushed fo...

Re: Bismarck's port rudder

The remaining rudder is the starboard rudder. For certain. The 'clean hole' statement may just represent a poor choice of phrasing. The rudder stock broke off just inside the outer surface of the collar where the rudder passed through the shell plating. (exactly WHEN it broke off, remains somewhat c...

Re: Bismarck and her contemporaries

To Nearchus: As I recall, the Japanese report, which of course I have only read in English translation, and perhaps in summary, doesn't really say much except that some projectiles came in close aboard and caused some splinter damage, etc. I am sorry if I appeared a bit evasive in holding back the r...

Re: Bismarck and her contemporaries

I must admit that I am becoming a bit discouraged about how this discussion seems to be proceeding. Mr. Gollin is refusing to answer even simple questions and continues to assert that I am attempting to engage him -- and I presume others -- in some sort of "game. As I can make no sense of this whats...

Re: Bismarck and her contemporaries

The Nowaki gunnery reports for Iowa's and New Jersey's are summarized, salvo by salvo, complete with spotting corrections observed and applied, in Part II of the Fischer-Jurens paper. Anyone who wants to can extract the number of probable straddles, and the number of guns in each straddling pattern,...

Re: Bismarck and her contemporaries

I will attempt to reply in detail: Mr. Gollin wrote: "A great attempt at de-railing the debate, but I won't bite at the "game"." I am making no attempt to de-rail the debate, nor am I playing any 'game'. I don't have time for games. I am honestly trying to find out what your positions are, and how y...
