Re: KGV turrets - pretty much the same as others

The point you seem to be missing here is that the KGV class had specific problems related to the quad turrets. It's already been pointed out (and strenuously ignored) that the British themselves noted the unreliability of the quads. If we want a benchmark for comparison, we don't have to look any f...

Well, to some extent they are intertwined. A shell delayed from the shell room, that misses a salvo is really no different from a shell that is delayed due to a jammed interlock.

Re: KGV turrets - pretty much the same as others

If you seriously wanted to investigate this matter, you could ask, "Would extreme sea conditions cause the American failure rate to triple? Or would DoY's failure rate be reduced to one third of the North Cape figure if the sea conditions were calm?" I already an idea of the output that can be expe...

It is absolutely not an average gunperformance and you can not blame it on the weatherconditions here because it was no problem for Rodney, or maybe Rodney was immune against bad weather!!!? from: navweaps.com http://www.navweaps.com/Weapons/WNBR_16-45_mk1.htm ) During the first hour of the "Final ...

Re: KGV turrets - pretty much the same as others

I Yes, we know, you are parroting information from a second-hand source even though you don't understand what it means. You have been given corrected information and analysis--why don't parrot this now? I seem to have touched a nerve here. I have rather patiently stated my position, that the KGVs, ...

Re: KGV turrets - pretty much the same as others

The figures that you yourself provided show the American ships with 88-90%, not 83%. You are trying to show that, in this context, 68% looks "pretty good." If you want to believe that a failure rate that's three times as great is "similar," you may do so. If you have read threads in which Scharnhor...

Re: KGV turrets - pretty much the same as others

Over a similar time frame PoW maintained 74 or 85% availability for an average of 79% over 30 salvos. Duncan I'm assuming that you conveniently "stopped the clock" here when PoW's entire main battery armament had failed due to various reasons and so she "ceased fire" and attempted successfully to w...

Re: KGV turrets - pretty much the same as others

Have you looked into when KGV's problems arose? Investigation of the gunnery records of King George V and interviews with several of her officers reveal that there were problems with the mechanical safety interlocks designed to prevent explosions within the turrets from being transmitted to the pow...

Re: KGV turrets - pretty much the same as others

I know what you're trying to say, but you are incorrect. Your own information shows the American ships having roughly one third as many missed salvoes. Comparison with Scharnhorst is doing no credit to KGV. Scharnhorst's guns were notably unreliable. One wonders how poorly KGV would have done if sh...

Re: KGV turrets - pretty much the same as others

If DoY's experience is comparable to the Germans' against Renown, tell me how many salvoes, DoY missed due to a shell hit to one of her turrets. "Gunnery Report, 'C'turret, 9.4.40: I. General." You will note that this report was from C turret on Scharnhorst, the turret least affected by weather, an...

Re: True?

Dear Duncan, PoW had only completed the physical installation of two of her turrets on April 27, 1941. IE, less than one month prior to meeting Bismarck. PoW had carried out one (yes, just one) live practice shoot, prior to going into combat. is that true? i ask some weeks ago, why Lütjens did not ...

dunmunro, I'm sorry, but you are completely wrong here. You are trying to use Idaho as an example, and we all know that if you fire all of your ammunition there are going to eventually have errors in drill and some breakdowns. That isn't what we are talking about with the KGV class and you know it....

Re: KGV turrets - pretty much the same as others

How many missed salvoes did KGVs suffer due to having to move shells from the farthest reaches of the shell rooms? Are you confusing mount unreliability with operational limits? There's nothing wrong with arguing that the KGVs had no reliability issues, but the RN disagrees. Of course the KGV's had...

USS Idaho

from US BBs by Freidman (page 352): "Only in 20 cases did all six guns fire. More often (forty-seven times) five of the six could fire together. There were twenty-two 4-gun salvos, thirty-one 3-gun, twenty-five 2-gun, and eleven 1-gun. On average, the interval between salvos was 1 minute 24 seconds....

KGV turrets - pretty much the same as others

Much has been written about the KGV class turrets being "defective"...but were they? Let's compare the PoW, KGV and DoY against some other battleships: PoW had only completed the physical installation of two of her turrets on April 27, 1941. IE, less than one month prior to meeting Bismarck. PoW had...
