Re: Richelieu vs. South Dak
"Salvo chasing has come many many times in my wargaming with my friends :) However, I can't remember any occasion during WW2 when a BB successfully managed to make such a thing. Hell, it was very hard even for destroyer Nowaki to escape from the 406mm 6-gun salvos... The reason why we don't see such...

Re: French Battleships
Tiornu,
thanks for your kind answer. However I don't really understand why the rate of fire would be slowed. You can fire guns 1 and 3, then one or two seconds later, guns 2 and 4 ; a few seconds won't make any difference. Would you mind explain me ?
Best regards,
Francis

Re: French Battleships
Their primary shortcoming was the inefficiency of their main batteries. Circumstances being what they were, they didn't get delay coils until 1942 (I think). Tiornu, I understand that the inefficiendy of their main battery you are talking about was hudge dispersion because of shell interference (th...

Re: Naval gunnery accuracy - question for M. Jurens
Gentlemen, I have ordered and read the article 'Fast Battleship Gunnery'. While wonderfull, the article opens the way for more questions. First, the authors talk about a spreadsheet to download in INRO's website. Unfortunately, I couldn't locate that file. Could you please tell me where it is ? The ...

Rear admiral Howard F. Kingman
Gentlemen,
I am looking for a picture of RADM Howard F. Kingman and I can't find any on the web. Do you know where I can find one ?
I would also like to know who is the senor officer between admirals Kingman, Giffen, Griffin and McMorris.
Thanks for any help,
Francis Marliere

ESM in WWII
Gentlemen, I have a question about detection of radar emissions in WWII (ESM as we call it nowadays). I'd like to know if Scharnhorst in late 1943 could detect allied radars ? In one hand, one can read that Scharnhorst had a passive FuMB 4 Samos set (and may be a Sumatra one), but in another hand , ...

Re: Tirpitz AA Fire
US heavy flak shot down about 25% of the total in the Pacific. Bgile, could you please tell me your sources ? I am interested by the subject and surprised because I was inclined to think that prior the introduction of VT fuze, heavy flak was not very effective. I think that according to South Dakot...

Re: Naval gunnery accuracy - question for M. Jurens
Gentlemen, sorry to post a new question on this topic, but there is another point I would like to discuss. As already said, the equation in the article was Ph = 10(E-TX) where X is the maximum range of the guns. I understand that the maximum gun range is achieved at 45° elevation. What about guns, s...

British guns at DS
Gentlemen, It is usually said that VADM Holland tried to close the range between Bismarck and his ships because he knew that German 38 cm could easily defeat Hood's armor. However, I found very few data upon the capacity of British guns to penetrate Bismarck armor. I guess that British guns can only...

Re: Naval gunnery accuracy - question for M. Jurens
Mr Jurens, does the INRO article you co-authored with Mr Fischer deals with that ?
In an old thread, you spoke of "Maneuver and Fire Rules" which were used by the Naval War College. Could you please tell me more about that ?
Best regards,

Naval gunnery accuracy - question for M. Jurens
Gentlemen, In a Mr Jurens's now well-known article (http://navweaps.com/index_inro/INRO_Hood_p4.htm), there is an equation that computes hit chances of naval artillery : Ph = 10(E-TX) Where: Ph = Percentage of hits K = Percentage of hits at maximum range of gun E = 2.00 T = 0.02 - (0.01 Log K) X = P...
