Mate, you are wasting your time. This game is developed by russians. Any ukrainian tank in this game will always be 10x nerfed, no matter what evidence you present to the developers. They could never accept the fact that tank made by ukrainians is way better than any russian tank.

It’s not like Duplet is underperforming but it’s like Russian heavy ERA is over performing Vs NATO-standard ammo so we expect Duplet to be way better as it is now? Isn’t it?
Yeah, russian bias is a thing. But in case of russian ERA there is no bias, IRL it is really capable of stopping kinetic rounds, so in WT russian ERA is performing accordingly - they just didnt have to make it better than it is IRL. But in case of ukrainian ERA they had to make it worse, otherwise we would have situation where ukrainian tank is better than russian, because they would be same in terms of firepower and protection, but Oplot would also have reverse which is huge deal in game.

It is literally underperforming, it should stop almost 400mm kinetic penetration minimum

I found this video, might help with the vertical speed discussion.
Clearly this movement is independent of the stabilizer since the tank is stationary. And it seems to be higher than 4.4 deg/sec.

I think this will also be fixed, seems to be the same hole as in this report. Community Bug Reporting System

How come duplet can’t deflect apfsds while relikt can?
the side ERA only intervenes against the rod’s trajectory at angles of 65 degrees or higher, whereas Relict becomes effective at a much earlier angle of 35 degrees. This results in the APFSDS rounds that penetrate Relict causing less damage than those hitting the Oplot’s base side armor, even though basic Relict ( without additional era packages)has a lower rated KE protection value. These two ERA types work differently, but I didn’t expect the difference in their effectiveness to be so pronounced.
It can deflect, but only deflect when the pen is already yellow or red😆

Well I guess we know now, lol

Turret armour is (hopefully) fixed.
Here is all the info that I managed to gather from russian CIS forum topic regarding Oplot:
The UFP -
This image demosntrates, quote “the early prototype of filler, stacked plates” that was later changed to homogenous plate in production searies.
It is this part:
The part of technical documentation for this specific part was posted with some editing with comments:
You can note that blueprint shows 3 rows of bolts it is because later Oplot variants have afromentionted section look like this:
The ERA -
Gaijin used this broshure http://uamicrotech.com/wp-content/uploads/2018/10/p04.pdf which is dedicated for the similar ERA as original Duplet but made by
A company that was established in 2018 , while ERA used for Oplot(and Thai variant) was made by "Basic Center of Critical Technologies “Mikrotek” ". Not to mention that Oplot itself was produced from 2009 to 2018.
If we to inspect the broshure we can already see the issue with the number of inner elements used -
Additionally it seems that new HKChPWSH elements use aluminum(I found explanation that it is less prone to corrosion resulting in longer shelf life) instead of copper for shaped charges. This and the size of charges indicates that it is less effective than original “ХСЧКВ34”.
In conclusion, if regarding ERA effectiveness there is room for debate and doubt, for 50mm plates between ERA there is none and it is only up to common sense and decency from Gaijin now.

This change would also explain the claimed lighter weight of these elements by the manufacturer.
That looks neat, nice to see a biy more info.
Quote? Can you provide the link/source to such quote? Would be another nice point in proving what kind of armor is there.
Just quoting what some tank enthusiast blogger said, the one that provided bluepring piece, not like official source quote.
Why is the kinetic protection one Duplet ERA provides is 140 while one relikt is 250 which the relikt is given the real life value it has. Based on this:
It should have a kinetic protection value of around 430 mm right? How is a dm53 round passing through two Duplet ERA and the hull and penetrating when it has a pen value of around 650mm? Are the reasons why oplot ERA bug reports are not going through because we don’t have “official” sources? Any update on this issue? I thought Duplet ERA was better than Relikt cause it uses linear shaped charges rather than the older method of moving plates that relikt still uses?

Does anyone have the source Gaijin used to give one duplet ERA 140 mm of kinetic protection? I’m not seeing that number yet on my searches.
The best we know is that they either used the advertised numbers for a completely different ERA called Duplet 2M which has smaller and lighter charges, or that they made the numbers up. Same with the missing 50mm plate, they can pretty much make up things and then require documents to prove what is already known.
Prior to war thunder, no one was claiming that BM-Oplot only has 2 steel plates in the composite or that Duplet only stops 280ish mm of kinetic penetration.
I’m getting really tired of this game’s “selective realism”. I heard that they sent the duplet to USA for testing. I guess we wait for either Ukraine or USA to release some document.

Well there is already evidence sufficient enough to at least give the ERA its proper values, duplet was fired at with 3BM42 at 100m and left only a residual penetration of ~93mm, meaning more than 400mm in penetration was reduced. You can watch this test footage right now on youtube. Many people have made reports with it and they’ve been labelled as “not enough info” or “not a bug” with some vague excuse.
I don’t think there will be any additional document released. I think they will intentionally keep the tank in this state even if there is new evidence, because if the armour was realistic, it would certainly have to go up to 12.7, and gaijin cannot have a squadron vehicle at the top BR. So I predict that it will remain in this state for now. We are probably gonna wait for new info + new top tier tanks at 13.0+ so gaijin can raise the Oplot.
