Request for Accurate Representation of M1 Abrams Armor and Spall Liners in War Thunder

Hey War Thunder team and fellow players,

I want to bring up several important issues regarding the in-game representation of the M1 Abrams series, specifically the M1A1 HC, M1A2, M1A2 SEP, and M1A2 SEP v2. There are some notable inaccuracies in how the armor, spall liners, armor penetration mechanics, and turret ring vulnerabilities (including the shot trap) are represented in the game, and I believe these should be addressed to improve realism and gameplay balance.

Integral Spall Liners in M1 Abrams Tanks

The M1 Abrams tanks, including the M1A1 HC and its variants, are equipped with integral spall liners. These liners are crucial for improving crew survivability by preventing the internal fragmentation of armor when it’s struck. However, this important feature isn’t currently reflected in the game, which gives a misrepresentation of how resilient the Abrams is in combat.

Supporting Evidence for Spall Liners

Here are some sources that support the inclusion of spall liners in the M1 Abrams:

  1. Tank Encyclopedia - M1 Abrams
    A great resource that outlines the importance of spall liners and composite armor in Abrams tanks.
  2. DOT&E Report on Abrams M1A2 SEP (2017)
    This report discusses the improvements in the M1A2 SEP series, including spall protection and other survivability enhancements.
  3. GAO Report - Operation Desert Storm (1992)
    This government report mentions the spall liners and armor protection systems that were integral to Abrams tanks during the Gulf War.
  4. Abrams Spall Liners Video
    This video explains how spall liners are part of the Abrams’ armor and critiques their absence in War Thunder.
  5. M1 Abrams System Technical Overview (Federation of American Scientists)
    A detailed look at the M1 Abrams system, including armor and survivability, which applies to all variants, such as the M1A1 HC.
  6. War Thunder Community - Abrams Turret Ring Issues
    A forum discussion addressing the absence of spall liners and issues with armor penetration mechanics affecting Abrams gameplay.
  7. War Thunder Community - Abrams Glacis and Turret Ring Inaccuracies
    Another discussion on problems with armor penetration and turret ring inaccuracies in the Abrams models.
  8. How to Fix the M1 Abrams in War Thunder
    A detailed thread discussing the M1 Abrams’ weaknesses in the game, including Point #3, where it is stated that the turret ring needs more armor to prevent excessive vulnerability. The current armor model allows these vehicles to be easily destroyed by shots aimed at the turret ring, making the tank far more vulnerable than it would be in real life. Autocannons can easily penetrate the turret ring, leading to instant crew kills, which isn’t an accurate representation of the M1 Abrams’ real-world armor protection.

Vulnerability of the Turret Ring

In addition to the turret ring vulnerability, another key issue is the ability of certain vehicles, such as the 2S38 and Gepard, to penetrate the M1 Abrams’ turret ring from the front. These autocannons are capable of exploiting this weak spot, effectively defeating the tank with shots to the turret ring, something that shouldn’t happen in real life, given the tank’s armor and design. The lack of proper armor on the turret ring leads to an unrealistic and overly exploitable vulnerability in the game.

Conclusion

The current representation of the M1 Abrams series in War Thunder doesn’t fully reflect the tank’s true survivability, particularly in regards to spall liners, shot traps, and armor penetration mechanics. By addressing these issues and including features like spall liners, proper turret ring armor, and a more accurate armor penetration system, the game could provide a more realistic and balanced experience. This would greatly improve the immersion for players and create a more authentic representation of the M1 Abrams series.

Looking forward to hearing your thoughts on this, and I hope we can get some improvements in future updates!

Cheers,
Max

Do you provide the info? to the site so they can incorporate it. Cause forums is not the site for it.

Where do I do that?

@GhostSoph
This guy will help. I’m assuming its part of the bug page but don’t recall.

You are using a third-party resource, mate. They are not going to accept those.

I’ll fix that, don’t worry about it.

Third party and cannot be accepted

only mentions ‘underbody’ IED protection

only mentions spall liners for bradleys though

the video is just a guy talking… need more conclusive proof sigh

the other website is also third party

the rest are inconclusive about the spall liners. We do know the latest variant comes with the liners, and the DU, but the older models, aside from a few trial vehicles, incorporated none of these features.

as for the turret ring. #gaijin_modelling

people have given more official sources and still failed to prove that the spall liners were standard on the m1.

the integral/integrated debate has not yielded proof that these are standard (to my knowledge, i may be a bit rusty on the updates)

mhm yea like i said I might update that with actual documents, but can you please tell me where I can put this message? (which forum or whatever.)

Usually, we make bug reports on here:

https://community.gaijin.net/issues/p/warthunder

but for now, you are fine where you are.
Can gather everything here and then compile a report.

Correct there are no disclosure about Abrams internal spall liners “yet”.
Even latest variant such as SepV2/V3 still didn’t show spall liners in their spec (even Abrams X didn’t)
But
XM-1 documents spec clearly list spall liner as its requirement. But when it became M1 Abrams such word completely disapear from its list and spec.
M1 CATTB also did show spall liner in it document.
M1 Breacher also did show spall liner in its spec. But when it became M1150 such word disapear again.

As you can see US did try to put / design spall liner in Abrams prototype base vehicles. But when they got accept into service such things suddenly disapear without any mention whatsoever.

Thing is. Images would prove more useful than documents because most tank specs dont list spall liners.

Actually if Abrams really did use internal spall liners / armor package that could prevent itself from spalling or some sort. We wouldn’t see spall liners hanging like a normal spall liner. Even if we could cut open and see the inside of composite armor itself. we still wouldn’t fully know. As i said US never actually clarify whatever Abrams has some sort of spall liners or not. if not then why they didn’t try put one in since M1A2 , SepV1/V2/V3
So in this case documents are more reliable.

The Abram uses “Integral” spall liners, they are integrated in the armor of the turret and front of the hull. It is not like the Leopard or T90M. Correct me if I’m wrong.

Meant to reply to Armen Lozone, you cannot see the spall liners, they are in the armor

We also need to add armor made of depleted uranium, if they haven’t added it. Different sources (Wikipedia and etc.) say that it was there and provided good protection

As said above, if you believe some vehicle stat is wrong you should submit a bug report, however bear in mind the following:

  • You should have “proof” something is wrong
  • Proof CANNOT be some classified (anything not public is risky) document
  • Proof cannot be dependant on opinion
  • And i assume it is clear that proof must be CREDIBLE…not some website without a valid source

I didn’t check the links in detail…i am just doing “global” comments…not sure if they apply

EDIT:
Also bear in mind that NOBODY in forums will be able to validate your data…only support will be able to analyse it.
I ASSUME it is a multilayer system…someone will make an initial check to see if your case has merits…and eventually send it up the chain…
MANY stats based bug reports are deemed as having unreliable documentation…hence the above suggestion to discuss it here first…but in the end it is up to you

abrams dont have spall liners, though it does have other issues in-game

you mean the composite armor? the one made of a lot of things including rubber?

No like I said, it has integral spall lining.
