Do you mean this pic?
What is actually from A4 round not A3
You know that LENGHT IN THERE IS THAT WHOLE FUCKING THING. Not only APFSD LENGHT
As you claim in here
I’ve asked you this question for the third time, and you still don’t want to answer it. What is the length of the penetrator tip and, most importantly, how long is the fin section of the projectile?
- What is the size of the penetrator tip?
- What is the length of the fin section?

You don’t know English? I thought I already explained everything. How can you not understand what I’m talking about?
Firstly, cos you really dont know difference beetween lenghts of PENETRATOR and CASING.
I really put this like you can understand.
you can have total lenght of 950mm
And inside can be 600mm Long APFSD Penetrator.
You’ve multiple times referred that PENETRATOR LENGHT IS 984 in m829A3.
And next, I’ve answered you what I have found about A3.
But you cant realise, there is no unclassified documents about that round to be found.
So now, I’ve asked you multiple times to give us actually proves of that M829A3 round. Not some steelbeast or reddit paint photos about complete different round also.
Here is the length of the entire round: 982 mm — let’s round it to 1000 mm, i.e. 1 meter.
Below, I have provided images of the round in cross-section. In your opinion, how much of the total length of the round is occupied by the tip and the tail section?
980mm.

Sorry for the confusion, I may have been a bit inconsistent earlier. But in my recent messages, I was clearly asking for the total length of the round, as well as the length of the tip and the length of the tail section.
I used the same calculations for the 3BM42-2. And here’s what I got. What did I do wrong?
Why did I get 511mm instead of 542mm?
It would help if you used the correct length and density numbers. You also did change the targets density and hardness number as well from the default of 7850 kg/m^3 for density and 237 for the Brinell number. Using the correct numbers and a Brinell number 7 lower than default gives you this.
This number is almost exactly how it performs in game
Even changing the hardness back to the default of 237 moves the perforation to 538mm
If we calculate based on your formula, the M829A3 should penetrate a full 30 mm more.
You’ll get the ingame results basically if you’d change the velocity to the correct parameter of 1.555 km/s like in game. Also you should use the correct diameter of 25mm, which will actually boost the pen. I also already said you should use the default number for the target which is 237. I just used 230 to show how close it can get with a minimal hardness change. Here is the correct M829A3 velocity
Here it is with the correct velocity:
Results are a 3mm difference from in game
I noticed that Dead Undertaker guy has one of the worst “tests” I’ve seen on this forum.

Yep.
And now he has also proven point , that he got no clue about penetrator lenght , since he’s swapping it beetween 750, 850 and sometimes 984
This reminds me of takes from the tiger who we not name.

I was talking about the round length of 984, but as it turns out, you didn’t even know that. You simply aren’t competent enough for this argument.
Yes, I can see round lenght indeed
I made a mistake with the terminology. It was evening, and I wrote it incorrectly. But my recent statements were specifically about the Round length.
Yeah and that 840 is took from a picture of M829A4, not 3.
It is measured using PAINT tools.
But if we imagine that would be about 820-840 , there is still that steel tip, and it is estimated to be 90-130mm and after that is DU rod.
Thing is, it is designed to break steeltip on eras and setting em off, and pen main armor on DU rod behind it.
It is not complete 800+ DU rod.
Quite literally the same stats as when you first posted this bs thread

There’s an ATK patent lying around on the internet for KET, which is pretty much a carbon copy of M829A3 but in Tungsten for export. This is how more precise numbers for the M829A3 have been found.
The patent points to a 630mm(give or take a few mm) DU penetrator with a 100mm(give or take a few mm) sacrificial steel tip. Hell, there’s even an accurate schematic of it on Wikipedia. I’m pretty sure this one comes from the patent in question in fact.
When it comes to APFSDS, War Thunder is very accurate as to their pen. The real problem with War Thunder is that certain armor are overperforming(Russian textolite) while other underperform.(SEP v3 hull, western composite in general) which lead to inaccurate results as to what shells can or can’t pen.

KE-W A3 uses the same penetrator as KE-W A2 but is equipped with a more powerful propellant charge, which increases its muzzle velocity and, consequently, its overall performance. This is also supported by the size of its penetrator. It’s essentially the equivalent of the M829A2—actually, it’s even smaller than the M829A2’s.
