Re: Bismarck at DS after the second turn

Hello everybody, while all the above considerations about uncertainties in the measurements are correct, I think we are here trying to reconstruct the relative position of each ship, using their cross-bearings and available tracks, while we are not much interested at absolute positions. The only abs...

Re: Richelieu and Jean Bart

Hi Alec, I do agree: re. RoF, it may not have been a problem, in this specific case. However, to fire a single gun out of the two belonging to the same half-turret, would imply to double the theoretical time to re-load and fire, and except the test mentioned by GiZi and this specific case, I see no ...

Re: Bismarck at DS after the second turn

@ Jose Rico: great idea. I believe Mr.Jurens could play this role. Let's see if this way knowledgeable people can start again discussing facts and evidences in order to reconstruct the battle, instead of insulting and mocking without any contribution. From my side, I will behave as requested, leavin...

Re: Bismarck at DS after the second turn

I can perfectly recall. However, despite Mr.Jurens suggestion (that was not for me ONLY, I hope), Mr.Wadinga ignored it and came in again to provoke , therefore he doesn't deserve such a kind treatment ! He should try to understand what I meant, answering to another provocation, with "Jasper's secre...

Re: Bismarck at DS after the second turn

The answer to the above petulant beggar (unable to understand what I intended for another person, not for him) directly from Jasper :

This guy should start justifying his own "theory" in a decent way (as suggested by everybody) instead of begging for a help he doesn't deserve.....

Re: Bismarck at DS after the second turn

Why is this guy still speaking to me, provoking after the tones here are finally ameliorating ? Because he wants a fight, having lost a discussion ! Was I speaking to him posting the above ? NO . I suggest to read back and TRY to understand (if able). Why is this guy not yet working (as suggested by...

Re: Richelieu and Jean Bart

Hi GiZi, I agree on almost everything you have written above regarding Littorio's. A comment and an answer for you: you wrote: "not only do most accounts of the action only describe Orion and Gloucester being targeted, but the image's caption also describes the salvo as being an over of Orion rather...

Re: Richelieu and Jean Bart

@ Thorsten, thanks Thorsten, clear as per "Seitenvorzündwerk" mechanism (that you had posted on this forum). Do you consider that in case of stable platform, the delay coils were still firing the center gun before the others to avoid interference or do you consider that in this (ideal) case the guns...

Re: Richelieu and Jean Bart

Hi Paul, the delay coils were devices used to delay the fire trigger impulse for some guns vs the others and thus to diminish the interference between too close guns when fired together during the same salvo. I think to remember that on "Scharnhorst"'s triple turrets (whose guns were fired usually w...

Re: Richelieu and Jean Bart

Hi Dave, if you compare Richelieu AAA with Littorio's as built, I would say both of them were not outstanding and had no radar. Richelieu initial design was for a dual-purpose battery of 150mm, but the triple turrets proved to be too slow to follow an aircraft and the shell too heavy to be loaded at...

Re: Bismarck at DS after the second turn

Q.E.D. Just philosophical and methodological vague considerations (as we were here demonstrating a mathematical theorem, instead of building an historical reconstruction). No alternative, no proposal for a different interpretation of facts, no alternative method to be used, no proof presented to cou...

Re: Richelieu and Jean Bart

Hi Alec, according to Jordan-Dumas, Richelieu had a max fuel capacity of 5866 tons (peacetime cruising), reduced to 4500 tons in wartime in order to maximize the underwater protection effectiveness. The range @ 20 knots was 8250 miles with her max fuel load. Therefore the range of 7500 miles looks a...
