Re: Bismarck's port rudder

18 leak pumps (Leckpumpen) each 15 m³/min at 12 m pumpingheight IIRC only 17 of 18 “Leckpumpen” were able to flood. One pump (boiler room 1) could only remove water. Each pump had a nominal capacity of 900 cbm per hour. Magazine flooding trials on Tirpitz confirm it (flow rate up to 961.8 cbm). Flo...

Re: Bismarck's port rudder

One should always read text with a critical eye. Yes, of course. I personally do not believe anything about Bismarck without reading the primary source. Yes, of course, there are always good books and bad books. However, in this context I can only speak about English books regarding Bismarck. Compa...

Re: Bismarck's port rudder

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. :D Hello Bill, more and more it seems to me that there are a lot of errors in ...

Re: Bismarck's port rudder

One good example of this is the oft-seen description of the floor plates in the center engine room being displaced about a half-meter, with no reference to whether this represented a permanent or a temporary deflection. Well, I’m not sure, if there is a misunderstanding regarding the German word “f...

Re: Bismarck's port rudder

Well, that’s indeed astonishing. The rudder stock broke at its thickest part. After all, it’s a tube of 82 cm in diameter with a 30 cm bore! I would expect that the hull around the collar or the collar itself is at least deformed.

Hello Bill,

Is there any visible damage of the shell plating near the collar?

Re: Bismarck's port rudder

Hello Bill,

thank you for clarification. I've brooded over the pictures for several years now and it still keeps bothering me how it is possible for the starboard rudder to extends into the port side so much. Is there any simple explanation?

Re: Bismarck's port rudder

I always wondered, if the remainig rudder is the starbord rudder for sure. :think:
It's almost unbelievable.

Let's start with a few questions: ... the fact that all of her communications equipment was placed above the armour deck. I know that is written in many books, but Is this really a fact?

Re: Bismarck against BB-57 South Dakota

But the armor and steel plate thicknesses in that article should be used with caution, because they're sometimes inaccurate. That's a serious accusation about a recognized authority. Can you give us an example? Are these gross errors? No, these are not gross errors. That's why I tried to avoid the ...
