Japanese CA's armor over-rated.

Post by spence »

Checking out various sources, I find that Japanese CAs had 25mm of armor protecting their main battery turrets. The game's data base gives them 150mm.
Thus their weaponry is basically immune to the 5" gun, 250 lb bomb and probably500 lb bombs. Japanese CA belt and deck armor ratings coorelate well with the same sources I checked, but this rating for the gun armor is just plain wrong.

You sure that's not just the lower limit of their turret armour? Most ships (on both sides) had weaker armour on the back of their turrets, and heavier to the front.

Pretty shure the Japanese simply had 25mm armor on all surfaces. They are fine looking ships but their massive superstructures made them a bit top-heavy. Armor at the level of the main deck (where the lowest of the turrets are) decreases any ship's stability. All things in naval architecture are trade-offs. More armor on the guns might well have decreased the ship's stability to the point where it was not a stable gun platform in any kind of sea.

25.4mm NVNC steel plates on sides, front, back and roof are correct for all heavy cruiser turrets according to "Japanese Cruisers of the Pacific War" from Eric Lacroix and Linton Wells II.

Goo-ood Morning guys,

Well I guess you missed my thread on this very subject last week....

I got Tiornu to confirm what you and I dsicovered - YES (they have no bananas) - Japanese CA's had only 25mm of turret armor![;)] I believe the Nachi class had 3" coamings (deck armor protection to the turret base) but that's it.

Sadly, we got no response that Matrix had any desire to change that.

Gentlemen, Start your editors![:D]

If a pair of players with a game in progress each modify the values in their editors, will the change take effect or are they stuck with the old ones?

You're stuck. The editor only modifies the scenarios, not the savegames.

BTW, does anybody know if it's correct that the Oyodo CL is credited with 63mm of turret armour?

(Cool, another star for me.[:)] ) I wouldn't be surprised if the Japanese CLs are overrated as well but Oyodo was a newer class that may have been designed and built with more armor protection for its guns.

...which I've always said is a weakness, not a strength.

The PBEM guys, fearing cheating, rode right over my protests however. [:(]

Howdy Terminus,

According to the bible (Conway's) and the other similar sources I have - CL Oyodo has 1" turret armor.[;)]

Wow, the Bible says the Queen Elizabeth class had 13-inch deck armor?
Apart from the old armored cruisers, no Japanese cruiser had more than 25mm armor for the gun mounts. For those who are really anal, 25.4mm is incorrect as the Japanese did not use the 25.4mm armor inch in any warships--though the extra 0.4mm might just barely fall within the manufacturing tolerances.

Yes, 25mm.
For example, each battery turrets of Takao class was a 160 ton.
Too heavy. Had to reduce its weight.
Only vital part have a heavy armor.

Hey, Nagato actually had something like that. After her modernization, she had 11in of armor on 3in of HT laminations. That's worth about 13in.
