It is maybe those dec armors are made of high tensile steel, which is kind of structual steel(Of course in real high tensile steel and structure steel are different, but Gaijin treat much stronger Ducol Steel as structual steel too)
Weird thing is that Mutsu, who has same high tensile steel used on that part, has RHA instead.

It’s just the dev server model being unfinished… I hope. The upper deck is made of HT steel, but the thicker lower deck that also serves as the roof for the engine room is made of actual armor steel so they have no reason to leave it.


No. VNC only used in magazine parts. Engine parts were 51~76 mm HTS still after the rebuild.

Maybe we need independent thread about HTS and DS seperated from ST. There were thread in legacy forum but in new forum it is not.

I thought that this happens when thicker/higher quality plates are added on top of the original plate, said original (now backing) plate becomes construction steel. This does make sense because layering plates isn’t as effective as one homogeneous plate, so the lower armor modifier (for the original/thinner plate) is warranted, but in the case of Nagato, no additional armor was added for the deck around the machinery, it’s the same as Mutsu, so there shouldn’t be any difference.
So basically if there’s no other thicker plates added, the original deck shouldn’t be changed to construction steel.
If it was only because of the deck being HTS, then all other ships like Hyuga, Yamashiro, Mutsu, and Hiei would have their decks as construction steel, which shouldn’t happen because HTS is not just construction steel! Also the 5500t cruisers Tama, Sendai and Isuzu would lose their belts and deck (something similar might happen to some British ships but I can’t talk about those), which would be nonsensical.

Granted, when looking at Kongo, both the new and original plates around the machinery are hidden and so get the low modifier.

I noticed something funny… Comparing Mutsu and Nagato’s armor. How can I prove that their claim, “The armor is there, but it’s hidden,” is a lie and isn’t actually there… It’s all easy to verify. I’ll try to file a bug report about this soon.

"HT steel plates are considered structural steel, and they do not show up in the Armour view

Not a bug."

They say there’s armor but it’s hidden, but in reality there’s no armor at all.
I literally filmed a video that confirms this.
If you look at the Mutsu’s deck, which has 69mm of armor, and try to penetrate it with a 66mm shell, you won’t be able to. The same logic should apply to Nagato, since the diagrams show similar armor. And according to the statement, “The armor is hidden,” that means it should be there and shouldn’t be able to penetrate. But it’s much more fun… There’s no armor there, and penetration is successful.

“Hm, yes, the Japanese used structural steel instead of armor for the lols”
Someone should tell Gaijin that structural steel doesn’t protect from bomb explosions the way high tensile steel does. Because it is armor.

Man I want the Shinano with the 10 cm AA guns :(

They’d probably skip her due to the aircraft carrier thing. Even though she would’ve been a terrible carrier.
No.111 was 30% complete though and had the same changes.

Actually treatment of HT steel is very dubious as Ducol steel. Some ships get it as armor and treated RHA(which is significantly stronger than HT). But on some ships get HTS as structual steel, which is little bit weaker tha HT steel. It’s problem of WT naval that proposed in legacy forum but Gaijin didn’t changed.

Mutsu’s HT steel is treated as RHA, meanwhile Nagato’s HT steel is treated as structual steel. And structual steel treated as 0.4 RHA effectiveness. So it is not problem that 66 mm shell penetrate 69 mm structual steel armor, as it only gives 27.6 mm protection. Still it is hidden. Just not enough to give protection.

Maybe you should test again with 25 mm or 26 mm penetration shell.

We literally have antifragmentation armor on our ships. For example, the deck of the Oregon City is made of it; it’s 28.575 mm thick, and a shell with 35 mm penetration can’t penetrate it, but it should.

It is 28.575 antifragmentation(0.9 RHA) + 19 mm basic hull structual steel(0.4RHA, and hidden as moderator saids), so about 34 mm of pure RHA. Can be blocked in chance. Armor is little more sophisticated then seeing only in view.

Can anyone here explain to me how it is possible for the yamato to get oneshot into its frontal magazines while reverse angling (the angled bulkhead cant be the problem then when the back turret would be the way more likely to pen shot) by the sojuz with its sap from 16 km out? unfortunately happened in a naval ec match at something close to 1 hour 30 match time so theres no replays but the shot was performed by someone i was in discord with and he confirmed it was sap to the angled front armor belt below turret one or two and i instantly popped. the snail sure thats how that works?

a shot similar to this (which, theres a surprising amount of areas which show 11 mm of armor, although relatively tiny spots theres tons of these close to each other) Now, that might be because it only shows the outermost layer of armor and the sap detonates on the simulated shot in the armor analysis on the bulkhead or some other armor plate behind that, the person that did the shot also checked the armor viewer afterwards and he said it might be because the armor plates behind are destructable? if thats true then you are an “easy” oneshot to any destroyer with sap in that whole area with 11 mm of armor covering the magazines after one single penning shot that destroyed apparently all your armor behind a 11mm armor plate? WTF

and adding to that i remember i was probably even more angled than in the picture shown. i was about as far angled as i could while still being able to bring both front turrets on target, praying for enemies not just shooting my unangled aft bulkhead. worked vs one enemy but russian sap apparently just too stronk?

edit: as this is in german it says:
armor equivalent vs the chosen shell type: 11mm and possible damage:
compartment and vertikal armor plate (though that changes to different armor plates if you move the impact point around)

Its because of things like this if you take a look at my bug report, thankfully it got accepted 8^). Community Bug Reporting System

Also here is a video of both the Yamato and Musashi dying to 5 inch American SAP shells from a Moffet

oh so it is related or the same problem as you described in your reports. reading through them i already had the feeling that yeah that might have been what happened there, considering there should be no way that the yamato gets ammo racked there at its frontal ammo racks while angled away at that range by the soyuzs sap.
Adding insult to injury just a couple of shots before that i did somehow (probably rng god was with me cuz you know that actually shouldnt be possible) set both his frontal ammo elevators or barbettes on fire. Well, at least in the somehow still buggy af damage screen (which sometimes shows all ships on fire everywhere, shows blacked out modules which arent blacked out anymmore for ages etc etc) Anyways what do you know, magically both fires instantly disappeared 3 seconds later. And then he onetaps me with this bs shot that i didnt even see incoming probably because of pl or whatever. really the snail takes and then she takes but on some naval days she really gathers the unholy trinity of bad rng, shitty servers, horrible unbalanced maps and teams and an absolute chain of crappy spawns right next to some random battleship that you cant even bring guns on before exploding to do you in.

So besides that rambling, does the armor behind that really break? or does it straight out just ignore some armor plates. This is really getting ridicolous at some point, like how long does it take them to introduce some proper fixes to the worst performing 8.7 ship by a mile?
Why does it have the by far lowest amount of compartments making it way easier to destroy 3 of them? Why is the interior modelled that bad (idk if its still missing internal armored compartments)? theres several accepted bug reports on the bug reporting website that could help it yet to my knowledge none of them (maybe except the hilarious exploding by midship aa ammo???) was implemented. And they hope people pay 80 dollars for a nagato to grind this 50% finished model of a ship?



Yamama also could be killed in frontal lobe of the any main turret, if shot get lucky, also with moffet SAP. Shells penning via small holes near barrels then reaching ammo with big chance of instakill.

yea its because bs gaijin modeling of the armor plates with the very very very small gaps where shells can go through and why sometimes the effective thickness is 11mm

我给你提供了图纸

With the update live, why does Nagato have lower armour on its turrets than Mutsu ? 120mm on turret sides vs 200~ on Mutsu?

Ps: Dont want to argue, i want to know the reasoning ppl did when designing this ship

304.8 mm hidden under 120 mm.

In refit, Japan did add 120 mm NVNC armour on the existing 304.8 mm VH armour.
