Re: Long Range Gunnery
The link is containing a gfx on real fall of shot of 16" /50 on distances of 25 and 35 thousand yards in comparison to the size of the Pentagon if you eliminate the splinters radius there were around 5 hits on a BB-ship size target . http://www.fas.org/man//dod-101/sys/ship/weaps/mk-7.htm So, a...

Re: Richelieu vs KGV
No, but Iowa straddled Nowaki with her first salvo at about 35,000 yds. Im not so familiar with US Battleships, but if I remember correctly, there was a revision of the gun mounts on Iowa (or another ship of this class)at the end of 1944 because of not negligible deviations between the gun mounting...

Re: Battleship Top Ten
first wave was a swordfish torpedoattack
following were bombing attacks
the number of downed planes were only the number the ship claims as own shooting downs

Re: Hypothetical Battle of the Java Sea...
Then, we have the historical precedent of Bismarck, with it's poor AA capability, being attacked by 15 Swordfishes out of which only 1 hit . the poor AA-defence performance of Bismarck was due to lack of adequate training prior to the operation Flak training was abandoned because of lack of time co...

Re: Long Range Gunnery
Here is a original chart with german dispersion data for single shots As you can see the dispersion was found to be dependend on elevation angle for salvoes they use an correction factor named "Streungswert Batterie" (battery dispersion factor) wich was simply multiplied to the 50%ige Läng...

Re: Two KGV's vs. Yamato
"Might as well throw crumpets at her" To quote a certain film. Its hard to beleive a 1000lb AP bomb traveling relatively slowly compared to a 1590lb AP shell traveling at around 2400fps could penetrate 9" of deck armour? This is an excellent argument. Really makes you think! no speed...

Re: Bismarck's port rudder
At the command "Versenken" closure condition of the ship was canceled, the bilge pumps were switched to pump in reverse direction and all? possible seaside valves were openend
The capacity of the 18 bilge pumps was about 16,000 tons of water per hour.

the guns were comparatively often used, but the biggest ships sunk by this weapon were, as far as i know, 2 italian cruisers.neil hilton wrote: However, the RN 15" 42cal fitted on the RN BBs and BCs were all very accurate pieces.

I thought the German system didn't use RPC in one of the axes and instead used "follow the pointer" in either elevation or traverse. you are mixing different aiming and firing procedures the german capital ships use the following aiming and firing procedures 1) main procedure RPC for elev...
