Re: More on KGV Class main armament problems

Hello everybody, "IF we are trying to get a "rate of fire" rather than just number of rounds fired over a period, then the first rounds should be ignored." ...again, this is what McMullen did in his table (http://www.hmshood.org.uk/reference/official/adm234/adm234-509guns.htm) and why I have always ...

Re: Matapan

Hello everybody, I have to partially correct the timing of the "long" message (http://www.kbismarck.org/forum/download/file.php?id=3532) and to add some info that I got from my friend F.Mattesini (who has written the most complete book on Matapan in Italy, edited by the USMM, Ufficio Storico Marina ...

Re: More on KGV Class main armament problems

Hello everybody, Byron Angel wrote: "HMS Lion - Jutland....1.45 salvoes per minute." Therefore much less than the 2 salvoes per minute of PoW (at least if they were salvos and not broadsides...). Range, please ? US ships were firing with another method than Bristish doubles semi-salvos... "USS Washi...

Re: More on KGV Class main armament problems

Hello everybody, "I wonder in which minute PoW actually got 10 shells away....Theoretically...she should have been able to fire two broadsides in a minute- 20 shells in all.." I wonder in which minute KGV actually got 10 shells away (having being her peak RoF 1.7 salvos/minute... was she possibly ar...

Hello everybody, Wadinga wrote: "What exact value is there in creating another equally imaginary and equally (un)likely scenario based on non-existent evidence" Mr.Wadinga should at least try to tell us a number (because a number of shots were actually ordered on board Bismarck)...

Re: More on KGV Class main armament problems

Hello everybody, "Even the crude average applied to give PoW 2 salvoes per minute in Santarini's table fails to acknowledge that in one particular minute she fired only one salvo and in another three. A huge Standard deviation." ? Hard to find a more constant RoF than PoW on May 24 (please see Exhib...

Re: More on KGV Class main armament problems

Hello everybody, Byron Angel wrote: "Matapan represented an extremely rare confluence of favorable factors" I do agree. I'm not aware of comparable day battles at average range with a much better RoF than the one showed by PoW on May 24. For sure KGV fired with a lower RoF on May 27 and her effectiv...

Re: More on KGV Class main armament problems

Hello everybody, "...One rpmpg was the average output expected by the RN for a battleship in WW1...." When a British WWII ship fired with a better RoF in anger ? Answer please, not generic statements. If PoW RoF was poor on May 24, then KGV one was simply awful on May 27 and this is not the case.......

Re: More on KGV Class main armament problems

Hello everybody, Q.E.D. someone has still to digest the RoF definition as used in the PoW GAR and the difference between RoF and effective RoF (or to use McMullen words, between salvos per minute and effective salvos per minute)... I suggest them to study a bit here (http://www.hmshood.org.uk/refere...

Re: More on KGV Class main armament problems

Hello everybody,
I wrote: "I prevent that I used the McMullen definition as per PoW GAR..."
my very bad English... It should have been "I warn you that I have used McMullen's definition as per PoW GAR". Sorry.


Bye, Alberto

Re: More on KGV Class main armament problems

Hello everybody, disregarding the implicit desperate provocations of the above post, just to correct the most wrong statement among the several incorrect ones: "Rate of Fire implies output as well as a time interval." Please now post a credible definition of RoF , not self made "ad hoc" definitions....

Re: More on KGV Class main armament problems

Hello everybody, "According to the Navweaps site the 14 inch guns were designed for 2 rounds a minute...That the KGV’s couldn’t reach there designed output on construction would suggest that their rate of fire was wasn’t particularly brilliant..." The same site (that I don't think is always right, a...

Re: More on KGV Class main armament problems

Hello everybody, "PoW was basically firing at a rate of one round per gun per minute. This cannot be deemed either a fast or excellent rate of fire..." A clear disagreement with Adm.Santarini (for whom the PoW RoF was " excellent ")... : which examples of actual comparable battles do we have in whic...

Re: More on KGV Class main armament problems

Hello everybody, [Commentary redacted. WJJ] Of course, this doesn't mean that there were not serious reliability problems with the 14" turrets, just that PoW was at least ready for action as KGV was, by the time they were declared "ready" by their commanding officers, having had more time to prepare...

Hi Dave, thanks for the reference and the interview. you wrote: "Yes, the chronology given by me above does need some correction. It was on the 27th, or X-1, that the second message, a long message, and the fatal, message was received." I see now what is this message. On March 27 at around 18:00 in ...
