What I find really interesting is the top speed officially reported for Tirpitz at 31.7 kn (I had never heard about that): impressive result for such a large, 3 shafts ship. Is your source reporting the date when this speed was recorded ? Can you please share the name of the document ? Unfortunatel...

In regard of the Denmark Straits footage frame rate: It's very unusal to stick out the tongue like Jasper?? does. The footage was filmed on 35mm with an Arriflex 35. The standard frame rate was 24 fps, but Lagemann's camera already had the adjusting knob for 18-30 fps. My DVD-version apparently has ...

Thank you Herr Nilsson for the information about the restricted rate of fire. Can you explain how the rate was restricted? Best regards Frank The rate of fire depends on the interplay of several work flows. The bottlenecks are: the shell hoist cage, the cartridge ring car and the shell ring car. Th...

Hello Mr. Nilsson, thanks, do you have any information about 'possible limit' of burners actually reached during Bismarck's or Tirpitz's trials ? As said, a less efficient fuel consumption at high powers would have affected range, not necessarily speed. During trials, Gneisenau reached only 30.7 kn...

2.1.5. Rate of fire A video recorded from cruiser Prinz Eugen during the Denmark-straight battle shows a sequence of Bismarck firing for effect at high rate (Wirkungsschießen). The rear turrets fire at 24, then 29 and then 32-sec.-intervals (at the correct tape speed). 24 sec. equals a rate of fire...

Hello Mr. Nilsson, thanks for all information. You write: "Because Bismarck's fuel consumption rate is different from Tirpitz'...", but I don't see yet why a different fuel consumption rate might affect max overload power (and max speed). It might affect max range only. Assuming Bismarck ...

3) You mention FuMO 23 radar. I have always seen FuMO 27 for both "Bismarcks" and FuMO 26 for Tirpitz in 1944 only. Am I right ? AFAIK FuMO 27 was useful to direct fire at night but not to provide fully blind fire, due to its unability to separate splashes. FuMO 26 was capable of fully bl...

Thank you Mr. Nilsson for clarifying the steel type. Re. max speed achieved by Bismarck, in addition to the 30.6 kn from the Bismarck/Richelieu-comparison, the Baron mentions a 30.8 kn in his book as max speed obtained 'on one occasion' in November 1940. I don't see any reason why Bismarck should h...

Seems to be reliable.

Everything above 156.000 WPS for Bismarck is just speculation and actually it's quasi impossible. Thank you very much. So I take 30,6 kts at 156.000 WPS as maximum speed for Bismarck and 30,8 kts at 163.0026 WPS for Tirpitz. This would make them about a knot slower than Iowa and Richelieu and about...

Hello Mr. Nilsson, 2) Kommando roof 200 mm non-cemented, are you sure it was Wh ? Wasn't around 150 mm the thickness limit for laminated steel ? Wasn't it KNC ('forged') as (e.g.) main turrets rear plates ? Kommando sides: 350 mm KC. Communication shaft should be 220 mm KC as well. Yes, I'm sure. W...

to 2) I took this from the book "Battleship Bismarck- A Design and Operational History of William H.Garzke Jr., Robert O. Dulin Jr., and William Jurens (moderator of this forum), with James Cameron, page 43. There it says: "The conning tower roof plates were 220mm of KC armor, the sides w...

Thank you for the critical question. This is exactly what I was hoping for...to find out what I understood correctly and where was I biased... This is a quote of delcyros on this forum under the topic "Fuel consumption Bismarck": "Speed data BISMARCK, accurding to MMF model based on ...
