Re: PoW's gunnery VS BSM's gunnery

Bill, I'm sorry that I expressed myself so directly but it'a pretty shocking when plain statements in the GAR are claimed to not to state what they plainly do state. We know that if radar ranges had been used there would have been written notations made on PoW's AFCT paper plot and this would have b...

Re: PoW's gunnery VS BSM's gunnery

Hello everybody, was Roskill on board PoW directing her fire ? McMullen was, and his account is the only one we can trust, not showing any sign of dementia (http://www.hmshood.com/history/denmarkstrait/mcmullen_letter.htm). Again, this refusal to accept what is written and clearly explained is the ...

Re: PoW's gunnery VS BSM's gunnery

Hello everybody, 4. No results were obtained from either Type 281 or 284 R.D.F.; it is understood that Signal School Officers are now of the opinion that Type 281 suffered interference and Type 284 was defective, although it appeared at the time that 284 was also suffering from interference. 5.

Re: PoW's gunnery VS BSM's gunnery

Hello everybody, back we are with such low insinuations of "dementia" (Tovey), "poor old sailor autobiography" (Ellis) or "failing memories" (now brand NEW referred to McMullen too) when faced to evidences that cannot be countered :negative: The PoW GAR doesn't say that radars were not working DURI...

Re: The reason for battlecruisers

Gentlemen, Although never confirmed - for obvious reasons,but I have heard rumours that it was actually an 8" shell from PE that not only started the blaze on Hood but was the cause of her demise. If there is the remotest possibility of this being true then surely it means that the reasons for buil...

Re: Bismarck Tirpitz Scharnhorst vs King George V Prince of Wales Hood

hello there emmm…this is interesting. RN 14 with 1460fps is of AoF 26.4 at 25000 yard. I didn't find the test mentioned the fall of angel. did they use 1460fps plus 30 degree? or they did include 26.4 AoF plus 30 degree course angel? I didn't see 30 degree is mentioned in the file either. thank you...

Re: PoW's gunnery VS BSM's gunnery

This idea is from a forum thread here which I can not find anymore. There were a intense discussion about if PoW shoot better than Bismarck. One idea is that Pow only had 5-6 guns most of the time and acquired 3 hits while Bismarck had 8 achieved 4 including one deep water hit which should have det...

Re: Bismarck Tirpitz Scharnhorst vs King George V Prince of Wales Hood

My understanding is that these tests were fairly flawed, as they used small plates of KM armor. According to Nathan Okun, the use of smaller plates degrade the armor's performance to resist penetration. What I find interesting is they also tested British armor in this test, full a full sized unit. ...

Re: Scharnhorst w/ 38cm's and other improvements

Duke of York did not use any other radar type to direct fire at Scharnhorst after the 284 went down. Neither did it use 273 to assist in spotting after the 284 was unable to spot the fall of shot. Instead it asked any other British ship via voice radio that could spot the fall of shot to forward th...

Re: Scharnhorst w/ 38cm's and other improvements

Hello everybody, "Type 281 was expressly designed for gunnery, both surface and air along with air warning capability. It had bearing accuracy of .5 degrees (30 arc minutes) which was sufficient to put the director's optics onto the target. " Sufficient to train optic, not to direct blind fire in t...

Re: Scharnhorst w/ 38cm's and other improvements

Thanks, therefore: 285 is a gunnery radar able to direct blind fire effectively, but we don't know up to which range it was usable. 281 and 273 are air and surface warning that can give the range (but not the bearing) that can be spotted from the flashes with witch "tolerance" ? 2 to 3 degrees I gu...
