M1A2 Abrams vs T-80U | M829A2 | Armor Penetration Simulation

Simulation of a M1A2 Abrams projectile hitting the frontal armor of T-80U.
120mm M829A2 APFSDS (4.9kg projectile, 4.6kg DU penetrator, ~21mm dia) at 1630 m/s
vs
T-80U hull front armor:
Kontakt-5 ERA (15mm HHA plate, 8 x 4S22 explosive elements)
+
50mm SHA + 35mm Glass Textolite + 50mm SHA + 35mm Glass Textolite + 50mm SHA at 68 degrees
120mm muzzle velocity (M829A2) - 1680 m/s. 1630 m/s refers to a distance of approximately 1 km.
SHA - Semi Hardened Steel (+400 BHN RHA)
The interior of the ERA block was simplified for technical reasons. Inside there are light brackets positioning explosive elements.

[@dejmianxyzsimulations4174]

What can be said about the result? The K-5 cannot defeat a projectile on its own, but it can effectively reduce its effectiveness if there is adequate armor behind it. The armor materials and their arrangement are not accidental and have their own functions. Determining its effectiveness on the basis of the passive efficiency of individual layers does not make sense.

[@IanAwfuls]

I'm curious about one thing, how it's possible that the projectile (M829A2) made specifically to defeat tanks like T-80U and T-72B(1989) after Cold War ended, when USA knew composition of their armor and after testing their armor is not penetrating it in your simulation? Is it due to some specification of the round that are classified which you don't know so you didn't include them or is it simplified model or maybe a little bit of both?

I am genuinely surprised how little loss was there when it hit the first Textolite but when it hit the second,there was little to practically none of the penetrator left Good simulation

[@za_pravdu1943]

well, the first armor plate and the first textolite messed up the shape of the penetrator, it warped the penetrator

[@hypernova3527]

The Kontakt explosion almost cracked the rod in half. By the time the first half of it disintegrated, what was left was like a secondary projectile hitting at a much steeper angle.

[@superuser7743]

The whole concept of APFSDS (I'll be surprised if I write it right) has one weakness - they don't like difference in armor. They waste much more energy when armor isn't homogenous and it has combined structure. Especially, when different lays of armor has different hardness.

M829A3 was made because A2 cannot defeat Kontakt-5 on the UFP of T-80, T-72 and T-90s. It’s a given that the ERA doesn’t stop the apfsds alone but in combination with the UFP; makes it immune to M829A2.

[@Sh-epard]

Honestly i'm not surprised to see this result, as i said in the past community post about this sim, it would hold if the Kontakt was struck and not only the composite armor. The logic is also simple to believe why the M829A2 was not enough based on the sim, if it was enough powerful the A3 was not necessary to be developed and fielded. New technology are fielded on both sides (armor and projectile), it's an eternal fight; new rounds with improvements on their composition (new alloy or new material used), design and propellant replace the old flaws, if there are any, as new materials are placed inside the armor package for the tank. Nice sim as always, i'm sure this will set some new debates or fuel the relative side's story about the shell being useless/the ERA-composite overperforming, but i'm confident the truth is the same thing i thought in the early lines i wrote (i'm not an expert with titles or studies behind me, i'm just an enthusiast with an opinion. Pure and simple).

[@Mathosalpha]

Results were kind of as expected. Though reading your description there may of been some minor issues with the projectile model. Actual penetrator rod mass should be 4.74kg. Diameter is close to correct for a simplified model, length though may be the main issue. M829a1 has a rod length of 680mm. A2 is longer but not sure by exactly how much, it's hard to say by the pictures I have. I've been using 695mm for L-O calculation, as it produces the correct mass with a simplified 21.6mm diameter. But that's simplifying the tip to a flat end, in reality it could be closer to 700 or 705mm.

Can you sim the A3. The A3 was made thicker (unusual for long rod penetrator) the steel tip. The assumption is that it is to improve performance against ERA as those changes aren't going to improve raw RHA penetration.

Textolite is only good vs heat. Ceramics work both vs heat and sabot.

Textolite alone is not effective, but when properly arranged, it can help the steel effectively damage the rod. Ceramics have hardness.

У вас кажется отсутвует задержка от детонации блоков 4С20/24. Движение плиты происходит слишком рано, ОБПС не успевает начать внедрение в бронепреграду. К тому же от взрыва происходит деформация самой метаемой пластиной. И максимальную скорость блок ДЗ в реальности так же приобретает не мгновенно.

[@KrypticWarrior2]

For those not understanding what is happening, the APFSDS rod is passing through Kontact-5 ERA, a type of ERA designed to defeat both chemical rounds like HEAT and kinetic rounds like APFSDS. It does this by blasting a metal plate away from itself to damage the rod of the APFSDS and make it less effective at penetrating the hull armor, which in the video you can see. Had the ERA not been present, the rod would have likely gone further into the armor, or through it.

Maximum velocity? The shell is going at its best 1.600m/s. 1km is very close and doesnt make much difference in velocity

[@orkako]

It's a 2003 missile, so 20 years ago, but the A2 version has almost the same characteristics as the 1991 A1 version, and the two missiles differ only in production technology. The penetrability of the bullet is 540 mm RHA at a distance of 2000 meters.
