The previous post shows how PoW struggled to stay on target; radar ranging, with a near continuous stream of accurate ranges would have made this a much easier task and a 2nd or 3rd salvo straddle was likely with numerous straddles after that.Alberto Virtuani wrote: ↑Sat Jul 28, 2018 7:38 am Hello everybody,
Perfect confirmation of Adm.Santarini posted conclusion. We have rubbished this statement in dedicated threads already, but these guys (RN hooligans) need to believe that PoW fired badly, to justify Leach's decision to turn away.Dunmunro wrote"PoW's gunnery performance was poor"
Very shortly my answers to Mr.Dunmunro most misleading statements (italic) (ignoring KGV that AFAIK was not her opponent at DS ):
"14In output: 74% " Bismarck achieved 86% (assuming 108 ordered shots)
"5.25in output (4 gun salvos) 3 " we don't know data about Bismarck, but NO HIT , therefore data irrelevant
"First straddle: 6th salvo" First hit probably at 6-7 th salvo for BS (hit on spotting top ???)
"Total 14in hits 3" BS probably 5
"Total 5.25in hits 0 " . BS 6in 0 as well
I add here the comparison between PoW and BS gunnery using McMullen format (http://www.hmshood.org.uk/reference/off ... 09guns.htm):
PoW_vs_Bismarck(108)_firing-1.jpg
Not a big difference as everybody can see, with a slight advantage for PoW in RoF (albeit an advantage for Bismarck re. precision). Again mathematics doesn't help the "deniers" side.
Comparing KGV "practice firing" against a target unable to maneuver and making 6 knots in another situation is simply a nonsense.
Can we now come back to the topic of THIS thread PLEASE ?
Bye, Alberto
As discussed you have no idea what Bismarck's output was. We have numerous photo frames of her firing, and IIRC, they all seem to show 100% output.
We know that she fired 93 x 38cm versus 55 x 14in for PoW. This gives Bismarck a 1.7-1 advantage in rounds fired and a 1.9-1 advantage in weight of metal.
We have little data on Bismarck's 15cm guns but they should have been effective at 14k yds and almost certainly would have been if Leach had continued the engagement. If Bismarck was having 15cm FC problems, then that's something that Leach could not know about. PE's 20.cm guns would have been devastating if allowed to maintain a good FC solution and of course I ignored the 14 x 4.1in guns available to Lutjens.
PoW fired 55 rounds and achieved 3 hits for a 5.5% hits. with 74 rounds fired this would equal 4 hits, and radar ranging would increase the straddle rate from 3/18 to ~7/18 so we have more straddles with more rounds per straddle and this will equal ~7 hits. However, even with near perfect output and radar ranging, PoW would have still be at a severe disadvantage with no effective 5.25in output.
