Re: Bismarck at DS after the second turn

Hello everybody, @Antonio, whatever the exact distance of PG from PoW at 06:00, it was something between 15000 and 14500 meters, for sure NOT the 197 hm depicted both in PG battlemap and in the PG torpedo plot... :wink: I don't think it is worth to try to establish this distance in a much more preci...

Re: Bismarck construction flaws

Hello everybody and welcome to "lightyear" ! while I do agree with everything Thorsten and Dave have pointed out regarding the sloped part of the turret front and I don't see it as a flaw by itself, I still find a bit strange (a "flaw" ?) that the thickness of these slopes is less than the one of th...

Re: Le Bismarck & Supermarina. LOS! Nº42

Hello everybody, while I agree that the Supermarina SIS (as well as B-Dienst) was able to decode some messages during single operations and the efforts of the Italian codebreakers have almost always been understated and not enough recognized, I'm not aware of any spectacular decoding unveiling with ...

Re: Le Bismarck & Supermarina. LOS! Nº42

Hi RF, while I see your point about RM pre-war lack of preparation, my point about the "shock" was not meant at all as a "surprise" because some cruisers were destroyed by battleships. I meant the total effect inflicted to the "small" Italian Navy (already weakened by Taranto attack) by the loss and...

Re: Le Bismarck & Supermarina. LOS! Nº42

Hello everybody, RF wrote: "surely not quite the same level of shock as the loss of HMS Hood was to the Royal Navy" IMO Matapan impact was much worse. Hood destruction happened during a battle while she was fighting and Hood was a symbol, but everybody at the highest level was aware of its vulnerabi...

Hello everybody, Wadinga wrote: "surely the naval battle for Crete was marked by 100%, total, Axis air superiority" ...the same local air superiority German and Italian Air Force had guaranteed to Iachino during the Matapan disaster ? No surprise the Comando Supremo decided not to risk other ships b...

Re: Le Bismarck & Supermarina. LOS! Nº42

...especially after Matapan clash, that obviously caused a great shock in the Italian Navy. On March 31st, 1941 the "Comando Supremo" ("Highest Command", Gen.Guzzoni) ordered to Supermarina (Amm.Riccardi): A seguito e conferma di quanto Vi ho espresso verbalmente ieri, Vi comunico, con le stesse par...

Re: Le Bismarck & Supermarina. LOS! Nº42

Hello everybody, I just saw the same message in the Bismarck Reconstructed KTB: BS_KTB_Vian_message.jpg Therefore Cernuschi's LOS article, albeit very interesting about Supermarina intercepted messages in Atlantic, must be taken with some suspicion regarding its conclusions about what was transmitte...

Re: If Bismarck had made it to France

Hello everybody, a very interesting discussion, possibly more belonging to the "Hypothetical Scenarios". IMO it's not just a matter of air strikes in France: please keep in mind that the twins survived all the air strikes (despite heavy damages) and the British lost 53 planes and used more than 4100...

Re: Bismarck at DS after the second turn

Hi Antonio, I don't see your positioning of Prinz Eugen as the most correct one, for the reasons I have explained here (http://www.kbismarck.org/forum/viewtopic.php?f=1&t=8335&start=345#p81831). We have to consider that the PoW gunnery plot shows salvo 13 fired at 5:59:45 from 15042 meters (16450 ya...

Hello everybody, Wadinga wrote: "Rowell's map shows a near instantaneous turn of 20 degrees at most taking 30 seconds. Have you ever turned 20 degrees in 30 seconds in your naval career?"
