Documentation of M1A2 / M1A1 HC Hull Armor Composition (1996–2016)

You’re entire findings revolves on this one form when there have been multiple primary sources given to you left and right. For clarification, this document is stating, if this-> then that-> assume this-> you get that. War Thunder uses this calculator for general guesses on their rounds even to the point it will behave completely false from the actual DU rounds. As stated, “Case of Penetration: Only Tungsten available” meaning it cannot directly calculate DU semi-infinite penetration in that software.

Again all thesis with the knowledge they contain in an unclassified level. Alloy means mixture of metals and they do not know the full extent of the materials used in DU to know its true capabilities. Since its mainly classified plain and simple.

You’re arguing against a point I’m not making. I’m not saying jacket = sabot. My point is that the paper does not prove “WHA always beats DU.” It shows tradeoffs. Yes, DU has lower stiffness than tungsten, but the paper also says DU has slightly better impact behavior in RHA.

Also, saying jacketed DU has the exact same issues as monoblock DU is too broad. The purpose of a jacket is to improve stiffness and reduce bending/break-up. The paper even references steel-jacketed DU penetrators as their own topic.

So the fair conclusion is: DU and tungsten each have pros and cons. The better round depends on full design, not just material. (Again classified) answer the following too.

I was allowed a max of 3 messages and wanted to know what a previous user said so I changed it over to that.

I agree the paper is not meant to prove DU vs WHA either way. That actually supports my point.

It does not prove “DU > tungsten,” but it also does not prove “WHA > DU.” It shows tradeoffs: DU has slightly better impact behavior in RHA, while tungsten has stiffness and sabot-design advantages.

So the fair conclusion is that neither material is automatically better. The better round depends on the full design: rod length, velocity, sabot mass, alloy, stiffness, and target type.

If you spend time to research it’s not because DU is not superior but DU is a major hazard and requires nuclear waste.That is too simple. Countries do not choose DU or tungsten based only on penetration.

The U.S. still uses DU in M829A4, so DU is clearly not obsolete or useless. At the same time, European countries often use tungsten because it avoids DU’s political, environmental, storage, and handling issues.

So tungsten being widely used does not prove it is always better future case. It only proves it is good enough and easier to field. The real answer is still design-dependent: DU has impact-behavior advantages, while tungsten has stiffness and logistics advantages.

Lastly, if you bothered to read the primary source instead of being so caught up in your LO nonsense it states the following:


If you follow enough to find proof vs just sleeping in LO all day you would see the following:

And to spoon feed you further some have or are developing and the list goes on United States, United Kingdom, France, Russia, Greece, Turkey, Israel, Saudi Arabia, Bahrain, Egypt, Kuwait, Jordan, Pakistan, Oman, Thailand, China, India, and Taiwan.

Lastly, another third party source as to what’s happening.

Only thing worth responding here is simple

You and the other clown have only shown the Source from LO based on thesis and other jargon I’m positive you don’t understand cause it was even difficult for me to put it together from reading it. Others have already shown primary government sources and you two want to die on that hill that’s on you.

Long story short your document doesn’t show anything of substance , however, Tungsten = less controversy therefore good enough round as an alternative to the environment health hazards.

Again United Nations attempting to ban DU rounds, because even though their superior along with other sources people have given you, are a huge hazard VS. some third party source you and the other clown want to die on.

Your document does not prove WHA is universally better.

A UN report that doesn’t give any data, and a 1990 test using horrible WHA and exclusively at low calibre dimensions? But LO doesn’t count when he shows his test data but the American one does even though both are funded by MoDs? Again you didn’t read anything that actually supports the argument.

Love how you also contradict yourself, somehow superior yet not. The data clearly shows (even “your” outdated tests) that WHA is superior the more you scale up. If you can’t accept it I’ll leave you in your delusions. The YM differences are easy to wave off if you have no clue what they mean, which is something you seem to lack.

Or as you like to say, nothing of substance while showing and talking about clear design restrictions and performance limits. Specifically mentioning how any benefit, as small as it might be is not realistically achievable due to said design limitations.

Though I am curious to see all those DU darts from the nations you mentioned :) oh wait, none of them actually use DU darts? What a suprise.

You can disagree as much as you want, DU tank rounds are just flat out worse in every. Every applicable source says so

Provided 0 sources. Have been spoon fed multiple sources from primary entities. Here’s my reply since that’s all you and that other clown are worth it when it comes to discussions.

Its basic physics and several studies show tungsten shatters catastrophically compared to DU. The difference is DU being self sharpening keeps its edge unlike Tungsten. It also has left post pen damage due to the round peeling off vs the DU being pyrophoric and burning everything in the vehicle.

Kennisgeving voor omleiding - This references the better pen due to self sharpening.

All of these show how DU is more efficient at penetrating and also post pen damage.

^ Blatant skill issue when real sources disprove your point XD

Not from LO.

This is their response when spoon fed.

Check the history all their delusions come from one third party source. Then it’s all “trust me” without any sources.

Anyone with a brain and a 30 minute you tube watch of Nile red would be able to understand that at high tempatures and pressure DU preforms better than tungsten.

If it ain’t LO then who knows.

EDIT: those are some good sources too good job.

And none of the sources show that, while the rest is based on 1980s findings to regurgirate “muh DU better”.

This has to be rage bait

Lmao, not even close.

DU rounds are tend to become fragile after certain muzzle velocity and its already proven by test results which is why M829 family cannot be fired at the same velocity that DM family can.

Tungsten is more resilient at higher velocity compare to DU rounds which is why Germany prefers it in the first place, not to mention if DU round was such a marvel of engineering other countries would already switched to it considering German Leopards can easily fire M829’s with very minor modifications.

USA prefers DU rounds due to bein easily producible thanks to their Nuclear productions.

Do show where these sources state KE grade tungsten heavy alloys are more prone to shattering.

Not tungsten carbide, not other tungsten applications, but WHAs.

Do you even know what flexural rigidity and ductility are…

This shows what DU does after entering a vehicle, showing micrograms of DU spreading into the vehicle cabin, covering ammo, crew and fuel.

At page 145 you can see more images of the inside of the vehicle, at page 508 you can see the microscope images of the inside sections.

It burns between 5000F - 10,000F as per this source Common Questions About Depleted Uranium - EnergySolutions

And nothing of essence was shown.

I was referring to post pen, while at higher speeds like you said DU is slightly worse, anything slower than 2000 Meters Per Second DU is better in every way assuming both rounds are same side and diameter.

Im afraid both have gone full ret-

Why did DM53 outperform M829A2 then? ;)

Could it be that, development in the US is lagging far behind, seeing as they still haven’t produced an alloy as good as the 30 years old WSM 4-1.

Listen, it’s not even like i wholey disagree, for velocities sub-1500m/s, it is clear DU is superior, WHA mushrooms too much, but at cannon scale, they’re generally equal assuming, hence why shorter but heavier DM53 beat the longer but slightly lighter M829A2 in Danish trials, and yes, they did in fact test them both.

Even today, US relies on Germany for tungsten penetrator alloys for the KE-W series like A1 and A4.

Interesting point to make seeing as Europe relies heavy on the US defense industry just to keep the nato war machine alive.

Internal damage will always no matter the speed be better, and the lack of mushrooming makes the round less likely to shatter. In your source

you say is superior under this limit all though the Abrams shoots at 1680 M/S compared to the L/55 with 1750 M/S. So its not only faster by just a little bit more and still is worse than the DU. < - (I should’ve clarified but DM53 is what im comparing too)

Both A1 and A4 are DU penetrators and KEW is only for export variants because some nations legally dont allow DU in there armory (Australia)
