About your change in the list regarding Nelson and KGV, if i understand you right you´ll rather be on KGV than Nelson in a duel. I would not, and i am sure a lot of people here agree with me. KGV was at least 6 knots faster than Nelson, and had much better magazine and engine room armour protection...

I'm getting the idea that Dave and Dunmunro both feel that the changes made to the installation on Vanguard were not necessary because the mounts were fine the way they were. I don't think anything I can say will convince anyone, so further contribution from me is probably pointless. Yet despite th...

Here it is, from an RN gunnery manual

"THE 5.25-in. Q.F. MARK I GUN ON THE H.A./L.A. TWIN MARK II MOUNTING. Plate 18. 159. These guns are combined High Angle and Low Angle Guns. The Mark II Mounting is found in all Dido class cruisers. The Mark I Mounting is found in King George V class battleships, where they fulfil the combined functi...

I don't believe the integrated fuse setting and hoist was used until the advent of the RP10 mount, when it was integrated with the US AAFC system. Of course, you said Anson had RP10 and I don't believe she got the US FC system so go figure. Rapid traverse isn't just used to acquire targets. It is n...

Dave's listing of all the different mounts is misleading. I don't claim the older ones were fast enough. Most US Twin mounts used during WWII were Mk28, and I believe the others were installed on older destroyers, not the cruisers or battleships. Most British 5.25" twins were MkI or MkII, NOT RP10 ...

It's quite true that the speed of train of the early model 5.25 turrets was found to be inadquate. However, in looking over the reports of The Prince of Wales flak performance at Kuantan, it becomes obvious that the ROF was really a non-issue in the AA role. The ROF was always able to keep pace wit...

When I served in M60A3 tanks, we could fire 3 105mm rounds in 5 seconds. First, the gun was loaded. The loader would stand holding another round with a third between his knees. The clock started when the first round was fired. Some people would say we could achieve 48 rounds per minute for a short ...

One of the factors which is often not considered is the degree to which an internal sloping belt, is vulnerable to waterline hits, diving under it, and the reduction in protected volume.

Very interesting, indeed dunmuro. I agree with you about Nelson, Nagato, Littorio and Richelieu. What´s your idea about them in terms of the list? About KGV I don´t know... :think: The KGV was a 14 incher while Bismarck had the 15" which in modern vessels (as for WWII) was a lot of difference (well...

KGV had a very deep belt. In fact the decision to deepen the belt was one of the factors that led to the reduction of main armament to 10 x 14" guns. The total belt depth was 24', and with typical loading would extend 14 to 15' below the water line. The belt thickness of 13.7 to 14.7" was the thicke...

If you are going to dispute the published accounts of the rate of fire of the 5.25" gun, why aren't you also disputing the accounts of the rate of fire of the 4.5" gun? Maybe the 4.5" number is too high. I doubt that it is, but according to your logic, the only way to determine rate of fire is to l...

Dunmunro, I'm sorry the facts don't make sense to you, but they are indeed the facts. An unsupported statement, by Campbell, does not equal a fact, it is an opinion, and he does not supply a reference to support that opinion. Campbell is also contradictory, since about the 5.25" gun he states the ....

Recalling my education and training in historical research; "facts" are not always engraved in stone, and are oft open to interpretation. This is even true of primary documents, that can, and sometimes do, contain erroneous information. The popularity or unpopularity of a position proves nothing. T...
