The BM Oplot-T Is... Concerning

Many people were looking forward to the BM Oplot-T prior to Tusk Force as it would be the first ‘true’ Ukrainian vehicle in-game, and Gaijin has obviously let us down as a community and I’ll explain why.

The protection for the BM Oplot-T is mediocre for modern top tier standards, the UFP can be somewhat reliably penetrated by most shells at around 12.0 (e.g. M829A1, DM53 and M338) whilst lacking the firepower to do the same in return. BTA4 simply doesn’t cut it, this is mainly a issue with the fact Ukraine is very limited with what types of APFSDS munition it can export (that usually being 3BM42) but the fact it also has poor gun elevation speed and horrid gun depression in-game becomes a catalyst to this issue.

There has been major controversies about the protection duplet/nizh should provide and I do believe this is something worth mentioning. Gaijin claims that two stacks of duplet should provide around 280mm of RHA protection equivalency whilst relict provides around 250mm - this is simply incredibly hard to believe.

According to ARC_Convoy_77 and from readily available images online, the UFP of the Oplot-T is missing a 50mm plate between the upper and lower layers of ERA. This is pretty significant as it would provide 133mm of RHA equivalency due to the angle of the plate - Gaijin however either doesn’t think it exists or believes it to be apart of the ERA dampeners, which is nothing short of ridiculous.

If modelled this would increase the average protection of the UFP from 577mm of RHA equivalency to 710mm, a sizable increase and would fix most of the protective issues with the tank (for the most part).

Some parts of duplet/nizh are also lazily grouped together defeating the entire purpose of multi-layered duplet/nizh, this is something inexcusable and should immediately be fixed, it creates nothing but a major weakspot for the vehicle.

This obviously had to include the side ERA coverage of the vehicle because only Russian vehicles may succeed in life (I’m joking).

More examples of this lazy grouping of ERA

The performance of duplet and nizh has reportedly also been underperforming in-game as well, tests and reports show that 3BM42 would be degraded by 78% by duplet, that being 356mm of RHA equivalency - and in some cases, 90% depending on what type of kinetic munition was fired at it. In-game however, two stacks of duplet only provide 280mm of RHA equivalency, significant below that 356mm figure.

If duplet/nizh was modelled correctly, it would alongside the composite UFP of the BM Oplot-T provide sufficient enough protection when compared to other 12.0 vehicles (e.g. T-80BVM, Leopard 2A7V and T-90M). The firepower most likely wouldn’t change as that’s a issue with the nation exporting it, not Gaijin mismodelling something - what can change is the adjustment of gun elevation.

Many sources vary on the elevation speed of the BM Oplot-T, what I’m sure about is the fact that it isn’t the same as the base T-80UD, Gaijin at first thought it was 1°/s (slower than the T-80UD) which showcases the mishandling/interpreting of primary sources.


What can be said for sure is that, Gaijin has butchered the BM Oplot-T, it had the potential to be the best vehicle in-game and especially in the protection department but potential bias/ignorance caused this not to be the case (Russian vehicles will obviously always prevail).


Thoughts?

  • They did a great job
  • They did a okay job
  • They did a bad job

Shoddily modeled top tier tank in war thunder? Im shocked and appaled! /s

Unless this is me being dumb, the BM Oplot-T has 4.4 °/s of gun elevation speed when aced, not even 9.9 °/s (I wish), it was initially 1 °/s on the developer server iirc until someone pointed out the idiocy of that mistake (it would never be worse than the vehicle it was developed from) then they adjusted the figures to be exactly the same as the regular T-80UD in-game.

If I’m not mistaken, it was the worst gun elevation speed out of any 12.0 vehicle

this its current speed on live, i never saw these numbers on the dev server i assume these were changed when the update dropped

(ok nvm im stupid didnt notice i was in arcade battle modes lmao)

They need to update the War Thunder Wiki then, I pulled that 4.4 °/s figure from there - could you remove your modifications and check if that was for stock?

didnt notice this when i checked lol

but yeah idk where gaijin got the 3.5 °/s for the oplot considering a development from the T-80UD

gaijin logic: tank from developed T-80UD with 4.4 °/s aced somehow lost 0.9 °/s through development to the T-84??

Happy to have helped in any way I could. I hope this tank gets modelled properly, it is one of my favourites alongside T-80U and other similar vehicles.

So not only did they skimp over several unique ground vehicles and modifications, the star of the update was badly implemented.

Subtrees never fail to fail.

Made a bug report for it. Not sure if I did a great job at making it. But hey, it’s at least worth trying right?

Modules research the module on Oplot-T or remove it from T-80U you have both of them have same speed

just like any other ERA ingame

pretty sure thats because a single ERA brick exploding will trigger the ones around it (atleast thats what i saw on the russian forum)

make of that what you will, but i would agree with the tech mod

The sources the devs have used do not reflect values of real Duplet ERA. Read: Community Bug Reporting System

You missed his point, the areas he points out has ERA stacked on top of each other, so the protection provided should be double against KE, just like ERA on the hull where the projectile encounters two tiles of ERA, and both of them reduce the penetration. Same should apply to these tiles that are grouped together, but gaijin treats these layers as 1 tile for some reason and they only provide the same protection as one tile.

yeah you are right my bad

to add to the whole ERA debate - the tech mod from the report i linked actually discussed all of that in this thread: BM Oplot-T - #2928 от пользователя Ralin - Наземная техника - War Thunder — официальный форум

tldr: the live tests match the ingame values so… i dont really know what to make of it

Did your thing get deleted? I’m unable to access it

According to my calculations, the tests don’t match in game values. Tests show 78% reduction of BM42 when fired at a 60 degree angle onto the turret. Ralin fired it at a 90 degree angle to achieve the same result (the turret ERA is mounted at a 60 degree angle so ralin’s shell actually got effected more than it should have if he had fired at the same angle as the video)

It should also be mentioned that at 90 degrees, BM42 penetrates less armour so it is defeated easier. I will try to do such in game tests to match the video as well and see if it works or not.

The btvt Image seems to be the case of being deleted :p

Yeah that’s why I didn’t wanna post it earlier.

Looks like our hands are tied in this matter. Neither the hull armour or ERA will be improved
