Armor Quality

You know it seems there are a few and often conflicting sources on armor quality out there. We have Nathan Okun and his information of Navweaps, seems pretty well researched. His formulas in short seem to put modern Anerican, British and German armor at about the same rating. Japanese armor too, tho...

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

There are differences of opinion but in all probability there wasn't much to chose from between RN and KM armour. I'd guess that to be correct. And likely both were better than US or Japanese armor. and it showed that 299mm of RN armour could be penetrated by the RN 14/45 at ~1460fps @ 30d target a...

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

however, please note the performance of the 14/45 against KM armour as given in actual trials and reproduced on the above webpage 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 p...

Re: Flooding magazines

Yes indeed it would make them unusable. But the ship would have a separate magazine usually for every turret of the main armament. Not to mention flooded magazines are preferred to exploding magazines! :D

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

What source ?

I find it extremely dubious to say the least.
Not sure where Christian got his info, but Navweaps shows the 28cm C/34 outperforming the 14" Mark VII slightly on belt penetration at most ranges.

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

Looking at Belt penetration numbers, Scharnhorst penetrates 11.47" at 20,013 yards, POW 11.2" at 20,000 yards. Horizontal armor on the two vessels was fairly similar. I'd say the only thing the Scharnhorst needs to do is close the gap quickly to get inside of deck trajectory shells, and/or...

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

A 300kg projectile traveling at 500m/s however has far fewer chances of knocking out the same turret in the same circumstances, because it carries 2.5 times less kinetical energy. One thing to remember though is that kinetic energy is equal to mass times the square of velocity, Take a look a Scharn...

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

Fire control and radar would both be vulnerable and not require a penetrating hit. Shells could easily start fires as well which could create big problems, if not handled properly even magazine explosions of course. And a turret need not be penetrated to take out - a well placed shell could jam a tu...

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

Gotcha. The decapping formula is a bit vague to me, mostly because I don't know which shells would be type 1 and which ones type 2. What I have been able to gather is if you have a decapping layer at .2 of the diameter of the shell you pretty well insure a decap, this being at lower levels of obliqu...

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

The thin upper belt of SH was a realy major design flaw! It would seem against battleships that it really would not make a big difference - 6" even though more than 2" is still not much of an obstacle for a BB shell. Cruisers and destroyers would be different though, you would get some im...

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

I though the Bismarck class and Scharnhorst class were pretty similar in armor protection? A little more deck armor for the Bismarck from what I gather, but otherwise pretty similar? Also seems the 11.1" gun was worse, but not terribly so in penetration to the British 14"/45 On the Prince ...

Re: Comparisons of Axis vs Allied Combat Vessels

I've heard that as well, Steve. IIRC, the US was probably a bit better prior to Coral Sea, but after Coral Sea they put a major emphasis on getting everyone trained in damage control, as well as providing more hardware on board to help, such as dramatically increasin the number of portable fire exti...

Re: Comparisons of Axis vs Allied Combat Vessels

I would argue that converted liners performed better than purpose built warships :D LOL, you may have a point there. However, most of the Japanese carriers that were destroyed easily were the ones that took bombs while air operations were going on. It's tough to compare the Yorktown class to the Ja...

Re: Comparisons of Axis vs Allied Combat Vessels

. For instance the Yorktown, a fleet carrier of the USN took enormous damage (for an unarmoured carrier) and still did her job. We see she took 3 - 500 lb bomb hits from Japanese Vals and 2 hours later is recovering aircraft and launching a return strike! In fact, the Japanese came back later and p...
