i'm just curious why IJN BB get faster reload when you upgrade their hull? (except for myogi and izumo) what's the correlation between hull and reload speed if their turret is still same as before? are there any historical reason for this?

Err, on what ships?

 

The reasons are balance-related, of course.

 

No way a ship can fire two 356mm rounds at the same time and fire again after just 30 seconds. Dem things weigh at least half a metric ton each.

Way back then, BBs used to have separate gun modules that needed to be researched like DDs and CAs. But for various reasons, WG amalgamated both hull and gun research into one module (the hull). So when you change the hull, you some times change the guns as well. Not necessarily the gun itself; might be different shells, charges, rangefinder, etc).

 

So hull module is kind of a misnomer, since you actually end up changing more than that.

Off topic somewhat but how about dd's? Benson especially, hull C vs hull B?

 

Spelling correction.

Well, Despite the same gun there is many unseen upgrades during the ship services.

If the Hull upgrade represent Era, then it will be easier for us to understand.

 

For Example Kongo Class have significant Barbettes upgrade in 1920, In the original British Design the Kongo Turret only have maximum elevation of 20 degree. The IJN enlarge the gunport and in 1930 They deepening the gun well and lowering the revolving structure deeper into the ship, as a result Kongo gain exra 15 degree Elevation on Her mountings thus increasing the Range.

However, non visual upgrade were happening inside the ship, In the Kongo The Shell room were located directly bellow the magazine, as the result of the deepening. The position were now reversed. The old kenyon Door (a tilting door which provided a flash-tight means of transferring shells between the shell room and the turret in original design were upgraded and now use Auxiliary electrical Power. This allow smoother flow of Shells to the Turret as also reduce manpower.

Hull C gets faster rudder shift and more AA for the cost of torret 3. Also it gets rid of most of the rust

 

Edit: this applies to all USN DD tier 5-8 (or 6-8) also it allows them to take def AA consumable. Fletcher gets it at hull B without losing any torrets

Impossible. Even a very well trained gun loader in modern tank take about 4 seconds to reload 120mm (12 cm) shell. 

Back in the day you have to load the projectile in the barrel before loading powder bags. You also have to get the shells and powder bags from below the deck which will take even more time. It should take about 40 seconds for untrained crews and about 25 seconds for very well trained crew

its wrong.

A May 1941 report by the German Artillerieversuchskommando, claim at 10,000 meters or 4 degree gun elevation. It is possible that well trained gun crews can reload at 20 seconds, which is necessary to meet a required ROF by AVSK of 3 shell per minute per Gun. that was possible because Bismarck have  5 to 10 "ready rounds" in stored in the handling rooms and gunhouses.

 

However Krupp official documents cite the ROF as being 26 seconds at a four degree elevation (the same of the game actualy), this was the fastest which her Ammunition hoist could handle, and due to design faults her ammunition hoist lead to breakdowns constantly.

Bismarck fired a total of 91 rounds during her thirteen minutes of firing at the Denmark Strait battle, which is actually less than one round per gun per minute.

 

furthermore Bismark only carry 112-120 Shells for each Gun. If She "pew-pew-pew" 1 shell every 8 seconds, she will depleted her ammo in 16 min. which is stupid thing to do
