Guns of 20-inch bore were being discussed with straight faces in the post-WW1 period IIRC.

Re: Monitors
Marcelo,
If you want to dig deeper on this subject, get a hold of the book "Big Gun Monitors" by Ian Buxton.

Re: A correct attribution for the "Flash Effect" photo?
Speaking of the photo posted by KevD ..... has anyone noticed the pair of gun smoke clouds? IIRC, Bismarck was firing 4-shot salvoes, A+B turrets, followed by C+D turrets at Denmark Strait. The forward smoke cloud appears to have palpably fallen astern of turrets A+B, while the after smoke cloud rat...

Re: Updating the KGV class
Hi Paul, Just an aside regarding your question about claims of invulnerability for Bismarck's main vertical belt. I do not believe that anyone has actually made a serious claim that Bismarck's vertical main belt was invulnerable to penetration. Given that her belt was <13 inches, such an assertion w...

Re: Updating the KGV class
Another possible factor in the thinking that led to adoption of 14-in as the main battery weapon of the KGV class: Assuming that these ships were intended primarily for operations in the North Atlantic, the typical ranges of weather, sea, visibility were certainly taken into account. The latitude of...

Re: Updating the KGV class
Gentlemen, As always many thanks for your contributions to what is obviously a fairly controversial subject. From what I can gather in my non technical mind it seems that the British 14" gun and the later shells were actually pretty good but they were let down by poor turret design. As has been men...

Re: Updating the KGV class
Hi dunmunro, Indeed the Mk XVIIB appellation for British 15-inch AP projectiles was found to have applied to both early war projectiles AND the new Cardonald design. It is not possible to conclusively state which projectile was used in the cited test based upon the text alone. However, given the pos...

Re: Updating the KGV class
Re the two pages the dunmunro kindly posted, there are some curious issues hovering around cited test series. Projectile - Shell APC, Hadfield 14-inch Mark 1 B.N.T. (weighted and plugged) – 1,595 lbs, versus - Ex-Tirpitz 12.5-inch cemented plate, sections 4 ft 6 in x 5 ft 6 in approx.: laid over a “...

Re: Wind Behavior: 0400 - 0600
One issue to be taken into consideration is that weather effects may in fact differ to a certain degree in localities separated by only a relatively few miles. For example, during the Age of Sail period, a line of battle of 35-40 ships maneuvering at two cables interval between ships might stretch f...

Re: Wind Behavior: 0400 - 0600
Great investigation, Marcelo. Thank you for sharing. I did a bit of looking in my library as well and found some relevant remarks in an old USN publication "Climate and Weather for Flight in Naval Operational Zones"; Aviation Training Division, Office of the Chief of Naval Operations, U. S. Navy; 19...

Re: Updating the KGV class
Besides there is no competition, everybody knows all US Navy vessels, regardless of freeboard, are "dry" ships. :lol: Indeed, Sean ..... far too dry from the point of view of the crewmen. Side-note - A cup of coffee has been traditionally known as a "Cup of Joe" in USN parlance. "Joe" refers to Jos...

Re: Wind Behavior: 0400 - 0600
Hi Marcelo,
I did a little hunting on the interwebnet. If the heading and speed of your own ship is known, it is possible to convert relative wind direction and velocity to true wind direction and velocity.
FWIW,
Byron

Re: Updating the KGV class
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 ha...
