He never states that they removed the M1A1SA’s DU. He never states it even has DU. He states that the Abrams being sent doesn’t have DU.
You’re falling for confirmation Bias.
Even if he did say it had DU, a youtuber isn’t a good source no matter their background if they don’t show evidence. This is just a YouTube Short talking about news dude.
Do we have a source on that? that number sounds absurdly high (just going by personal knowledge and logic, i might be wrong).
Yes, we do. It has been posted here constantly and featured regularly.

I want to see the Abrams be buffed as much as anyone else, but we shouldn’t make things up to do so. There are other ways we can do this.
Fat with what
What’s in the tank that makes it so fat
I wonder
Bro, Sep v3 did not start until fy 2020. The biden administration came out last year say they were going to start using hulls from m1 in storage to speed up the production to get Ukrainian tanks faster.
Larger gun, ERA, new system components, DU turret inserts present on the HC onwards.
If you actually cared for evidence, you would have noticed that a Spall Liner would require nearly three additional tons on top of its current weight. That would bring it into the 70-ton weight class with the Challenger 3.
oh wow. that’s a lot of weight.
in my head it does not sound right.
(note that this is not an argument for Abrams having spall liner, i’m just trying to make sense of the weight for my own sanity)
for example Kevlar KM2 (the one US military uses) weighs about 1.44g per cubic cm (using 1.5g for math convenience).
so if you want a 1cm thick liner it weighs 15kg per square meter (1.5x100.00/1000).
Lets say you double that (or use a better and denser kevlar) for more protection making it 30kg per square meter.
Lets count on the very high end here and guess you need 20 square meters to cover the inside of the tank. that makes it 600kg (30x20) now add some thin metal, lets say 2mm steel at 7.85g per cubic centimeters making it 7.85/5=1.57 (1.6 for ease of math) grams per square centimeter or 1.6x100.00/1000=16kg per square meter. again 20 square meters used to count high gives (16x20) 320kg
soo 600kg 2cm thick kevlar and 320kg 2mm steel gives 920kg total, lets round that out to add mounting hardware and such making it 1000kg or one metric ton.
now keep in mind that i counted high on every number here and even made the kevlar quite thick.
so how that becomes 2 metric tonnes by their calculations i do not understand.
The SEPv2 was a 2000s Era tank used primarily against Urban Combat. At the time, the threat was RPG type warheads and missiles, not Kinetic Penetrators. DU was not seen as necessary for the production run until the v3.
I do not know much about the math behind it. It’s just what they say. I’ve also been told that Kevlar is a general term referring to several things in the military.
I am simply putting forward a document you requested. Anything I say is less valuable than what is inside that Document.
The sep v2 is a 2007 tank with multiple blocks inside it like every other tank. The SEP v1 was likely featuring the 5 prototype with hull armor. Hence why they removed the limit of 5 hulls on the 2006 licenses.
Show documentation and prove Gaijin wrong. That is how these things work. Assumptions do not cut it.
Here are the 1999 and the 2006 licenses showing the removalof the 5 hull limit.
And here is the part of the 2001 document talking about testing the new turret and hull armor.
True, i used specifically KM2 version of kevlar that is the military grade one for the calculations.
Thanks for the source :)
the numbers just doesn’t make sense to me x)
but they probably know more than me on the subject.
I see that, but can you direct me to where it states specifically that DU hull armor was added for the SEP V2.
I do not see it. All I see is the indicator that the hull has been reworked by adding a new turret assembly and complete refitting of the entire vehicle. It does not mention DU additions.
I’m not a genius when it comes to math, but I can comfortably say that Spall Liners between two armor plates does not make sense based on logic. If the Kevlar is not in the plate, it should be seen when looking inside Abrams series tanks, but it is not visible indicating that it does not exist.
All of these documents predate SEP v2. And being that over 75% of the U.S inventory is still V2 do not expect to see any documents released untill 2029 when the V3 fielding is set to be finished.
Okay, but where does it talk about the DU.
People are not arguing between two armor plates, they are arguing between last armor plate and an inner thinner metal plate that isn’t armor but is instead a bendable metall and bends away instead of making more metal fragments (brittle vs pliable metals).
I’ve seen many claims about Kevlar between the armor plates.
And if there is another plate behind the one intended to stop fragmentation, it wouldn’t make much sense, no?
Think about it. If there’s a plate behind your spall plate, it will just cause more spalling.
i just said that though.
