Re: Richelieu vs. Bismarck

Dave Saxton wrote: ".....Max HP produced ......Littorio:139,561" Hi Dave, the figure for Littorio's ship is correct as this was the maximum power produced during machinery trials (producing a speed exceeding 30 knots, albeit at very light load). However, one curious point is that, due to ...

Re: Richelieu vs. Bismarck

As for the ineffectiveness I read it somewhere and just found this quote of Thorsten Wahl: On the other side the Richelieu had a very powerful machinery. The HP output was increased in comparison with the german machines. aditional the weigth was roughly 500 tons less according with the german piec...

Re: Bismarck and Iowa

Combat results -the UW protection/TDS-Double bottom wasnt impaired by the 2 ton charges of the X-Crafts. despite beneath/nearby explosions Nevertheless the ship was rendered off duty due to massive shock damage. But there was some flooding I guess? There was some flooding but Tirpitz was saved by t...

Re: Royal Navy at War - A Sailor's View

Hi all, I've just discovered a series of documentaries posted on Youtube in January 2017 that feature some great footage of the RN in various phases of the war and thought I'd share. I'll just post the link to the ones I've watched in its entirety so far - the first features colour footage. Royal N...

Re: torpedoes and torpedo bulges

Thanks, I'll do that. I wonder if Barham was ever modified, I believe she was only hit by one torpedo, yet the result was catastrophic, every time I see that film of her blowing up I think of those poor chaps inside her - were there any survivors? Barham was bulged but not rebuilt as per Warspite, ...

Re: torpedoes and torpedo bulges

Thanks for that. I realise that the effect of an explosion underwater magnifies the damage (rather like the 'Dambuster' bomb), but I'm puzzled as to why over the years that battleships were being built that so much was spent on providing upper hull protection against heavy shells that so little tho...

Re: torpedoes and torpedo bulges

Gentlemen, Yet another question for you! I was looking at a picture of a QE class ship and the enormous anti torpedo bulges she had on each side, yet in WW2 a number of ships were sunk by torpedoes, including her sister ship Barham, Bismarck and Yamoto. In addition, a number of ships were disabled ...

Re: Yamato and Musashi

With the Deutschland class the difference was calculated to about 15%, unless my sources are wrong. This is more plausible than 2%, considering that riveting requires overlap joints and much more framing. You have to a make a distinction from hull weight (IE the part of the ship that can be welded)...

In any event the above was little more than a summary of PE's KTB and doesn't provide enough info for any analysis.

Re: Yamotoand Mushashi

Yamato and Musashi used riveted construction. This meant that it was 15% heavier than it would be than if it used welded construction. That means it would have the same full load displacement as the Iowa class if it had been of welded construction. IIRC, the weight difference between welding and ri...

Re: Jasper, Schmalenbach and 6 salvos...

Native German speakers, please feel free to correct me, but "Gegner brennt" by my understanding translates to "Enemy is burning" of "Enemy is afire". It would not suggest that a major explosion has occurred. Byron That's what I would think as well. The interesting thin...

Hi All Hi Antonio, I'm not sure exactly who notated the map or to be honest what it exactly means! If you follow the lines that seem to connect to the notations then the wechsel or change note seems to be just before 06.00 and it also notes what seem to be shell splashes between 05.58 and 05.59.
