I think the game can calculate exactly that.
It would be more problematic if it had to change the durability depending on whether the layer was triggered first or second.
🤔 shouldn’t the second layer of era have better protection than the first layer? Since the first layer will slow down and deform/unstabilize the dart which should make the second layer more effective 🤔
No, at least not in the case of Duplet. As it was mentioned gazillion times, the second layer is covered by a (much) thicker plate than that of the first layer, and since ERA uses hollow-charge effect to cut the round (whose body is still in the plate at the time of penetration/detonation), more power will be released in the plate in order to reach the round.
And be it 30mm or 50mm HHRHA or soft steel, it will remain to be a greater obstacle than 15mm cover of the first layer. The other thing is how much space there is for the “air pocket” to let HEAT charges affect the round, but likely not enough to compensate for the volume of the steel layer in any way.

So few days ago when discussing soviet breach models I notice that Oplot is missing outer driver’s hatch seal moddeled, leaving it w/o accidental ~400m hardspot unlike any other T-80.

Also many protrusions on the hull roof that conviniently cover the turret neck are also not moddeled, unlike…T-90M :)

Wo!! That a lot man
Most of the time it seems like the bug reporting manegers just do it solely out of bad will.
Someone showing a pic of a heat round with 550mm of pen perfectly penning the side bags with a supposed 600mm of ce protection without even taking into consideration the side armour should be obvious.

Hello everyone,
I want to add some solid, legally verified technical data to this discussion regarding the “Duplet” ERA efficiency on the Oplot-M / Oplot-T. Many threads are closed due to a “lack of primary sources”, but the actual manufacturer of the armor components has open, non-classified specifications that completely contradict the current in-game ~550mm kinetic limit.
I have officially opened a bug report regarding this issue on the Gaijin platform, which was immediately closed with a generic macro response, but it contains all the primary files:
- Link to my report with attached PDF specifications: Community Bug Reporting System
- Issue ID: eqeoHy05g0pt
All technical data attached to that issue is taken directly from the official portal of Ukrainian Advanced Microtechnologies named after V.O. Khitrik (UAM) (State Registration/EDRPOU: 41354204, Primary Legal Activity/KVED: 72.19). This company consists of the original engineering core of the State Enterprise “BCTO Microtek” and is an official licensed contractor for KMDB (ХКБМ), the developer of the Oplot.
According to their official product data sheets and specifications for the 4C22U protective element (which contains the KhSCHKV shaped-charge cutting blade physics used in the Duplet tandem array):
- The manufacturer explicitly certifies an APFSDS capability reduction of up to 50–60% (“…так і від бронебойно-підкаліберних снарядів (до 60%)”).
The Physics: The 4C22U/KhSCHKV element relies on detonating flat shaped-charge jets aimed perpendicularly across the incoming projectile’s path. The massive transverse velocity (up to 8000 m/s) physically cuts and destabilizes the long-rod penetrator. This geometric vulnerability applies to all modern monobloc APFSDS (DM53, M829 series, etc.) regardless of whether the core is tungsten or depleted uranium.
The Math vs In-game Reality:
In War Thunder, Duplet acts as a simple flat armor modifier adding a static ~120-150mm value (effectively identical to the 1980s Soviet Kontakt-5). However, if a modern APFSDS round with ~600-700mm of penetration hits the 4C22U-backed Duplet layer, the ERA mechanism alone must reduce its residual penetration capability by roughly half before it even touches the base multi-layered passive armor array of the Upper Front Plate.
Furthermore, peer-reviewed military academic data from the Hetman Petro Sahaidachnyi National Army Academy (“ТАНКИ І ТАНКОВІ ВІЙСЬКА: вчора, сьогодні, завтра”, 2014, ISBN 978-966-2845-00-4) confirms that during state trials, the Duplet array completely neutralized French OFL 120F1 APFSDS rounds fired from a Leclerc tank at 100 meters, leaving only a minor 20mm superficial dent on the base plate.
Gaijin’s decision to treat a multi-layered modern tandem system identically to a basic single-layer 1980s ERA block is a massive historical underperformance. Please check the linked report and support the case so the historical team cannot keep ignoring primary factory data.

funny that this copium doesn’t end still while tank has best key characteristics of soviet/russian based tanks. 6 sec reload, mobility forward and backwards, but they are still complaining

Current ingame implementation is ~620 limit at 68° impact angle for the entire armour array in the hull fron, of which 341mm is from passive 60+30+50 plate and 279mm from Duplet module (including metal plates and separators). This roughly matches the lowest estimate from the domestic trials on which we have quite alot of data. While performance of single “brick” of Nizh is indeed underperforming, the entire protection theme is roughly true to life, this is done for the game convention/technical limitation, reasons.
The UAE testing info is very limited, we got the document title page and few snippets from the result section, unfortunately this is not enough for Gaijin standart.
It doesnt? The “key characteristic” of soviet/russian tanks is equal hull and turret protection that can stop all top rods from its enemies, Oplot can’t stop the most common enemy gun fire - those being Leos and Abrams.

armor doesn’t exist in this game if you face somewhat okay player, kid. and if something like “bug thunder” happens, it doesn’t matter how paper your tank is, you can tank 152mm apfsds with IFV like Freccia or Puma. key characteristics are mobility, reload speed and gun handling. the only reason why oplot can’t stop Leos and M1s is that it still doesn’t have great gun depression and 5 sec reload, but that’s just it. along other “Japanese bias” in TT it can pretty much stomp top tier
It does because →
majority of players are not aim monsters. You are blowing this out of proportions. Not to mention that past 600-700 meters hitting weakspots on targets moving on uneven terrain is a 50/50.
Armour does matter and Russian tanks are the clearest example, as do Strv 122s.
None of those except mobility are “best key characteristics of soviet/russian based tanks” lmao
Even mobility is just above the “mid”, reload is mid again, gun handling is atrocious due to -4 depression and 4.4° max elevation speed on Aces.
So yeah, I literally have no idea what the hell are you talking about here lmao.
Guess who you gonna kill faster.
or
“Armour doesn’t matter” is a complete nonsense take
All that to say, Oplot is not a bad tank, but it is barrely mid.

Lets not argue with someone who is obviously here on bad faith alone. They always tend to bloat the forum with their arguments.

I don’t understand why it’s so hard for them to buff the Oplot’s UFP armor when they’ve been given proof multiple times already.
they might have others, probably from the Ukrainian front or the export manual.
They are saying we cannot use those, nor give them, but they clearly do.
Remember when they did an article to explain the Abrams LFP armor and used a sensible/classified image, and it’s a member of the community that pointed it out.

Double standards
i’m gonna kill both fast enough if they just show their turrets or driver bill acceptor, because those are literal weakspots. shooting upper frontal part of turret even away from breeching gives you chance to wipe out gunner and gun itself and no sektri docs will ever fix it. and yeah, armor does matter, that’s why type90, type10 are so high in BR. such a weak tanks
You are dodging the question and we both know why :)
Mobility and firepower also matter, and nobody denied that, stop attacking strawmans.
At this point you clearly being unreasonable.
