T-64 vs T-62 with Kontakt-5 explosive armor | Armor Penetration Simulation 

In theory, the 3BM22 has a penetration potential of 450 mm at 2 km

My prediction was wrong. A combination of 3BM22 being better than I expected from my experience playing War Thunder and not realizing how important spaced armor is to defeating a damaged APFSDS penetrator. Even relatively thick solid steel didn’t stop it.

I expected it to penetrate, but didn't expect it to go through that easily.

So even if the rod is ruined, without angle to divert them, a broken rod is still very potent?

Interesting, even though the ERA shattered and deflected the projectiles there wasn't enough space in between for it to stop penetration.

Well that was interesting

That's an interesting result. I really didn't know which way it would go. Could you do a test on the T-62M-1's Brezhnev's eyebrows? Bonus if you put ERA over them.

Interesting result👍

Interesting result. I think that if the same test was tried in the UFP of the Hull, it would have been able to deflect it. The section hit was relatively flat so even the damaged penetrator was able to make it through.

Pretty much what I was thinking was going to happen. K-5 isn't bad ERA, but T-62 is regular RHA, even a damaged APFSDS is going to punch through with ease.

Lots of people seem surprised by this result. People don't realize just how big of a generational gap there is between steel armor and solid shot, and composite arrays and dart rounds. Composites aren't "a little better." It's a totally new game.

When I saw your poll I knew the answer must be yes, 3BM22 would have no problem at all against ~230 mm + K5. It's a relatively modern penetrator and while K5 can reduce the effectiveness of kinetic penetrators, at the end of the day it's only 230 mm of steel to punch through. T-72 (base variant) turret + K5 might be a closer competition.

armor needs spacing to break up the projectile more looks like. i wonder how it would do with kontakt 5 on the brow applique armor tho, might stop it then

The upper K-5 plate was like "i had nothing to do with this, why do i deserve it?"

What about Kontact-5 being suspended further away from the tank? 2x the distance? 5x?

what app do you use for these?

Interesting, 1mm diameter metal ball can kill at rather big distance in the atmosphere, not in vacuum (2m+). Is there any point in making the grid larger than 0.1mm in order to normally see the impact of possible fragments with a diameter of 1 mm or more?

Would it be possible to use a thin material to model the crew and in that way, show the internal spalling damage? Especially interesting for simulations where the projectile doesn't penetrate the armour.

Can you do 88mm vs RHA with Kontak-5? Im curious if kontak 5 can stop world war 2 shell. Or 105mm apds

I don't think the guy in the turret is going to be too happy after this.

I think the thickness of BM22 helped resist the shear stress from the ERA.

Would be interesting to see a hypothetical scenario where the object 279 got kontakt-5 on its upper front plate, or even its side armor, nice simulation though as always!

Oh well i was very wrong. Forgot how much spacing is necessary for the effects of a single ERA layer to manifest.

would be interesting to see it against DM22 or DM33 of the L7

Wow spaced armor is important

If the ERA had it rear plate be the thick one and the rod hit higher up on the ERA, it mightve had a better chance of defeating the projectile. But as is, the front plate of the Kontakt 5 is "wasted" by being pushed onto the aft of the forward-moving rod. A better design would have a thicker rear plate so that as it is pushed away, it feeds into the tip of the rod as it moves forward. The ERA being longer would also naturally help by having more material to feed into the rod.

Where are the florks though?

how do you do this?

Excellent simulation as always! Can i suggest a sim where a BR482B 130mm shell from is7 hit a side cheek of a t29 turret? The 200mm part i mean...

I always understood that eras was good against heat and marginally usefull against kinetick

Oof yeah, lower turret ERA isnt going to do much go the rod the upper though

125mm HEAT would be interesting against this combination of armor

Can u do a 2a46m-1(kba3?), t64bm Bulat shooting a hotter 3bm22 or 3bm42? Supposed to shoot the same ammo as t-80/84.

Id like to see k5 on a 30mm plate spaced 500mm away from main armour

What program are you using for simulations?

How long the shrapnel will be fast enough to kill or damage things after penetrating? They are moving at hundreds of meters per second after penetration, but how many impacts will it take before the shrapnel is harmless? Will post-penetration shrapnel behave like sand flying around at supersonic speeds?

Can you do the 7,7 cm K. Gr. 15 m.P against a British ww1 tank or so? For anyone more interested, 2 main Field guns that where used as AT guns by the germans were the 7,7 cm FK 96 n.A. L/27 and the 7,7 cm FK 16 L/35 as well as all captured french, russian and british guns drilled out to 7,7 cm (thats the whole reason, to be able to drill out captured guns, but at the same time deny the enemy to use your guns with their ammo) with also barrles of 7,7 cm with L/27 and L/35 length. They both had 3 dedicated AT rounds (while the normal He rounds with right fuze setting will work as well) namely 1. K. Gr. 15 m.P (Kanonen Granate 15 mit Panzerkopf -> Cannon Grenade/Shell 15 with AP head) beeing a normal HE shell but instead of the normal impact fuze it has a big special hardened special steel head with an extra designed (AZ f. K. Gr. 15 m.P) Impact Fuze under it, going in at 6,85 kg with 230g of cast or pressed filler beeing TNT, Amatol or something else more potent like PENT. Going at 465m/s with L/27 and 525-600m/s with L/35. 2. K. Gr. 15 m.P (Bo. Pr.) Beeing the same round but instead made of a different steel drilled out and beeing 7 kg. 3. K. Gr. 15 m.P m.L (meaning mit Leuchtspur -> with tracer) beeing also 7kg heavy and having a really big tracer pressed under it.

ERA really fascinates me. You can: Shoot it with a rifle without it exploding. You can burn the tank down without it exploding. If you can trigger one of the elements and it explodes, the explosion does not cause a chain reaction! This all sounds like magic to me... I do know that C4, TNT, and a few other explosives can burn without exploding and you can hit them with a hammer, or even shoot them and they won't explode. However, these ERA elements must have a primer, right? (primers are sensitive explosives used to detonate the above mentioned explosives which are otherwise reluctant to explode)

good example of how obsolete RHA only armor "arrays" are

Penetrator and rod : oh no! Anyway

I would like to see leopard 1A1 (120mm gun, L44) against T72 turms turret like in the Video.

Hi. Can you do simulation "Polish cavalryman charging Panzer III E front plate in 2000 km/h"? Thanks alot.

Can you do airplanes bombs vs tanks like guided and unguided.

I don't know if it's really feasible and/or useful data, but would it be possible to run it without the ERA and then compare the kinetic energy of the remaining penetrator after it exits through the back of the armour? Since the penetrator remained relatively intact even after the ERA, it'd be interesting to see just how much the ERA reduces the projectile's penetration capabilities

Thx for the work. But could you do the future/past engagements with t62 against leo1-2,

man you really gotta get the tungsten or DU rod simulated

It seems the flat mounted ERA with some buffer space behind it works better than this solution. At least compared to some of the other simulations you have done. I wonder how much of a factor projectile velocity effects the effectiveness of ERA. I would think a faster projectile would be less effective. But then again, if the speed is gained by a lighter weight, maybe not. Would it be possible to try a few identical test at different velocities to see? Something like a near muzzle velocity for close shots, then velocities at the medium and longest effective ranges for the projectile.

what about the T-64 fireing HEAT?

oh f I thought it was relic until I read in the comments it is K-5

Isn't ERA specifically a counter against shaped charge warheads?

Do tank crew men get breaks on health and life insurance?

Should be a definite possibility in Ukraine, though the Ukes also have 3BM42 as well.

By the way does anybody know how Anti tandem ERA is made? Turkish new one, Chinese IV - how it works ????????

"Hit"

9mm vs body armor?

Can u do the 3BM22 vs T-62M-1 turret with or w/o Kontakt-1?

So the explosion does nothing or is it not modeled? I would imagine the shockwave is much faster than the round, and I also would've imagined the shockwave wouldve deflected it a bit atleast

do one of taco bell vs jeans

So, i was wrong.

It's homogenous steel armor after all

Т62 отправляют на фронт модернезированные с "бровями брежнева" а на местах уже устанавливают поверх контакт5. И именно с такой проекции сомнительно что т64 пробьёт лоб танка т62. Успехов автору изучать материальную часть.

Like a knife through butter You need some more protection, steel alone won't keep you safe

ну контакт-5 не предназначен останавливать подкалиберные бронебойные снаряды, он против кумулятивных боеприпасов

Interesting if 'Nizh" can deflect it. Is it possible to make Nizh simulation?

Can you just make the simulations a bit longer

it seems heavy era is less effective against non-long rod apfsds?

Why not just put 3 ERA blocks to make triple the protection?

Expected

m1a1 abrams vs T-80U please.

Although ERA give some addiction to the armour protection, the basic protection of AFV's own armor is very important. We should always know that the ERA is not reusable.

Hi! Could you please simulate the "Nozh" reactive armor? It is a very interesting way to protect vehicles.

Kontakt these nuts 🥜

😊

RUSKY BIAS

So what I'm hearing is the Kontact-5 Russia is gonna strap to their T-62's (if that) ain't doing jack shit...

ERA is to counter HEAT rounds not APFSDS right?

*Uralvagonzavod wants to know your location*

t62m with kontakt5 ?🙂

Can ERAWA deflect it?

*Do not correct simulated.*

So the upgraded T 62 are still shit for modern Battlefield

Hmm, the simplest round of that type and so result... For what that contact 🤔🤔

It does not looks like Kontakt-5, more like Kontakt-1, which isn't considered to be anyhow effective counter to kinetic penetrators. kontakt-5 have internal plate which is feeded to penetrator this one just explodes to sides.

I expected such a result. This defense is designed for grenade launchers.

Skill issue

If russia is actually putting k-5 on t-62s that is pathetic

So adding modern ERA won't stop very outdated projectile from going through very outdated tank. So scrap metal projectile vs scrap metal tank is 1:0.

that implies that they actually have ERA and not a sheet of rubber lol.

n1

First

LOL

Penetrator is not impressed.

I feel like if the era exploded a little bit more late it would be more effective?

This is obviously not true, the "Abrams Killer" family of tanks (T-62, T-62M-1, T-62 M obr 2022/23) is impervious to any damage by solid rod penetrators! (/s) (It would be interesting to see how effective stacking blocks of era on top of each other is)

Stillbrew turret on a chieftain would stop this

Слава Україні!

need test ! Ukrainian Explosive Reactive armor knife !

Russian bias
