Re: closing up bismarck during daylight action

Hello, I agree with Mr. Chuckfan3, we have witnesses (e.g. officer responsible of central shaft turbine room, Junack) stating that, inside Bismarck vitals, they had not even realized that the ship was doomed, with their machinery (center turbine turning "slow" as per last order), lights an...

Re: Redesigning Bismarck

Hello Mr. Wadinga, re. Admiral Graf Spee (I agree this is out of topic and we should open another thread to discuss it) German damage report lists all damages that were not reparable, structural and to equipment at pag.12): no mention to auxiliary boiler (that was probably repaired at Montevideo, po...

Re: Redesigning Bismarck

Hello Mr. NCC1717, you are right, however at pag.12 of list of damages (https://drive.google.com/file/d/0B12aaMD-x_k_dGpBbFdrczQ5NTA/view?usp=sharing&resourcekey=0-CqV3WnGDOjVjHRqXpjp1kw), no hit is mentioned to have penetrated the ship vitals, not even n.3. Lubricating oil purification system s...

Re: Redesigning Bismarck

Hello Mr. Jurens, thanks a lot for your answer and precious info. It's precisely my understanding, reading German damage report. Regarding the chances to get back, however, I disagree: in 1941 Admiral Scheer got back to Germany after an even longer and more successful cruise, avoiding British patrol...

Re: Redesigning Bismarck

Hello Mr. Jurens, would you mind to please share here a summary of your conclusions regarding damage to oil processing system ? Which hit are we speaking about in relation to numbering/plans present in German report (https://drive.google.com/file/d/0B12aaMD-x_k_dGpBbFdrczQ5NTA/view?usp=sharing&r...

Re: Redesigning Bismarck

Hello Mr. Wadinga, possibly I was unclear: I don't say that doubling output for H-39 would have been a trivial matter for MAN (despite their design was almost same as Panzerschiffe engines), but I say that final decision had already been taken by KM. Orders for 48 of these engines for 4 H-39 BB's we...

Re: Redesigning Bismarck

Hello Mr. Wadinga, you are right when you say that "MAN were no longer in receipt of Kriegsmarine support from 1933 onwards but were free to develop what they wanted", however they were not funded to develop what they possibly wanted. Researches at MAN were seriously slowed till 1938, if n...

Re: Redesigning Bismarck

Hello, H-39 class battleships (six of them were actually ordered in summer 1939 by KM and two of them were even laid out, before works were cancelled at war start) were last fully designed and detailed KM BB's, AFAIK. They had a pure Diesel propulsion plant for 29-30 knots speed (12 MAN M9Z 65/95 fr...

Re: Were Bismarck and Tirpitz ever together ?

Hello Mr. "Biggie Cheese", I hope you will be able to post photo from your great grandfather's diary, as very few such images are available. Until now, I have only seen photos of the two ships together in R. Gehringer / A. Bonomi Tirpitz books (volume II, photo # 7, 9 and 10 taken on May 1...

Re: Redesigning Bismarck

Hello Mr. Mostlyharmless, while I see your points (however all your proposed changes have pros and cons), IMHO main flaw in (Scharnhorst's and) Bismarck's design was KM poor decision to give up Diesel propulsion for large vessels in 1933, coming back to steam and turbines. Researches at MAN were not...

Re: Group North and Group West

Hello Mr. Nilsson, when you say: "Based on the intercepted shadowings reports, Group West calculated a crossing of the 60° latitude line at approximately 2 p.m. on May 24th. Group West then suggested to Group North at 9:30 a.m. a transfer of command at 12 p.m. Group North communicated this to t...

Re: Group North and Group West

Hello Mr. McWilliams, Baron von Mullenheim-Rechberg and J. Brennecke in their books say that Group North would have already passed control of operation to Group West exactly at 12 on May 24, that look anyway more or less in line with map posted by Mr. Malara or even more to North. It looks like it w...
