Hi guys, a question related to wind. What was the effectiveness of putting the wind in the long range gunnery calculation? The firer can only measure the wind direction and speed at sea level, on firing the shell will climb many thousand meters, passing by atmospheric layers with different wind dir...

Yes, very interesting and it confirm RN statements regarding wind and seastate conditions during the final battle.

Having started the ball rolling, I thought you might have spotted this already: Thanks Wadinga, i must have missed this one! Re Dave's statement that the difference between 14/15/16" guns was marginal, i know this is going a bit off topic but it has been claimed that Bismarck's main armour was not ...

Fellow Contributors, Off topic but I think relevant. The politicians of Britain and France had seen a generation of their young men slaughtered and desperately tried to stop it happening again via maintenance of Treaty. The warlords managed to sleepwalk/ cajole / con their populations into embracin...

None of the 35,000 ton treaty battleships were worth building in view of the international arms race in the late 1930s. The Japanese were expected to build 16 inch/46,000 ton ships to complement the Nagato class. The Italians already built 15 inch/40,000 ton ships. Then the Bismarck 15 inch/44,000 ...

Gentlemen, I'm going to try your patience once again! Going back to the original question of updating the KG's. In an earlier post which seems to have got lost in the debate about the seaworthiness of the KG class, I asked why that it was possible to build the 'Nelsons' with 3 x 16" turrets and sti...

Thanks for your reply, I often wonder when the 3 QE's were extensively rebuilt, the RN did not take the opportunity to 'Up engine' then (if there is such a word) and make them faster and even more heavily armoured, particularly as the 'Treaty was being ignored by most of the other nations'. This wo...

Mmmm....I don´t quiet agree. In the mentioned site there is a picture of a launching, the "torpedo" was launched almost horizontally, question would be how far would the bare inertia take the torpedo before it goes to the bottom or comes to the surface, according to if it is hydrostatically positiv...

Too late for an edit. We also have to remember that PoW was being hit and near missed continually, with each near miss drenching parts of the ship with tons of seawater:

Another synoptic chart:

Norfolk 0400: BP 997.9

Norfolk 0800: BP 999.5

Suffolk 0800: BP 1003.3

I'm certain that they stated true wind in the log. Here's a device to extract true wind from relative wind:

I think they were used as mortars, but the concept is very similar to a DC thrower.

I find it simultaneously fascinating and dismaying that this discussion has somehow morphed into a competition between the KGV design versus American battleships. I do not recall Dr. Brown mentioning anything whatsoever in that respect. Prince of Wales' DCT 15-ft rangefinder was quite unlikely to h...

Like Byron, I consider the opinion based on all the wartime experience garnered over time regarding all the ships of the class by D K Brown to be more valuable than the single trials experience of Constructor Pengelly. Quite so, Sean. Trials are customarily run in as good weather and smooth sea sta...
