Also considering that there is no spin on the shell and its not a perfect model the results would prob be worse for the poor t54 crew, one of the late IS series might have been a better test since afaik it was the threat of those heavy tanks that made the british army consider producing such a monsterous gun and the 120mm they ended up using.

[@NathanOkun]

I saw a test result of a 105mm High Explosive Plastic (HEP --US term for British HESH) against a heavy log barricade directly in front of and close to an armored car (thin armor, of course) with a 37mm (?) gun turret. First was a shot using a regular impact-nose-fuzed HE round, which blew a small hole in the logs and displaced a couple of logs around the impact point, but no damage to the car. Second was a HEP round. No more logs except the bottom layer bolted directly into the ground. I didn't even see a piece of the other logs in the picture of the still-undamaged armored car from the front. Third, another HEP round into the front upper hull of the car. The turret was still in the picture, but torn off and on the ground several yards behind the car body. The front of the car hull was blown completely away and opened up like a tin soup can with a large fire-cracked detonated inside of it. There was some other pieces, including one front wheel, a few yards behind the car off to one side. Light armor does not help against this kind of projectile at all.

[@rolandlee6898]

HESH is extremely overrated and misunderstood. Light armor wouldnt help against any kind of projectile fired from a tank gun. There is very good reason why HESH never really caught on and is currently being phased out. Its application is extremely limited, and in a modern setting its far less effective than MP rounds currently in use. It was made out of the idea that HE does sufficient damage to heavy armor that is otherwise very difficult to penetrate. It kinda works in theory but not really in practice. In practice the effect on a tank between a regular HE and HESH is virtually the same and is almost entirely limited to external damage. When it comes to barriers, regular HE with a relative modern fuze, is actually far superior. HESH will always invariably detonate on the surface. HE can be set to detonate with a delay (something we've been doing since WW1), which would allow it to penetrate into or through a fortification or wall and detonate in it or behind it. Something HESH cant do and something all modern HE-MP rounds are made to do. The idea that HESH is good at blowing holes in walls for breaching is also false. Breeching HE rounds use the impact-delay function to detonate inside the barrier. Likewise this makes HESH rather awful at destroying fortifications, its always a surface detonation, which does next to nothing to the structural integrity of any half-decent fortification. Thats why no one uses HESH. Only the British did, just as they stuck to the rifled gun. Reality has finally caught up with them and all the fanboys who know next to nothing about weapons are crying because the Brits are done putting blind nationalism over common sense and science and are switching to L55.

[@Bordpie]

@@rolandlee6898 Against homogenous armour HESH works quite well, but since we have moved on to composite layered systems they are largely ineffective against (modern) tanks. It's not designed for breaching walls but sending shockwaves through it creating spalling and damage on the inside of the target, including concrete structures. It was originally designed for concrete structures and fortifications and is why it has been used for so long. HESH always dentonates on the surface if the object is rigid enough to deform the projectile and set off the fuse. It will go through a thin skinned vehicle like any HE projectile. A standard HE round will not penetrate reinforced concrete much before it detonates anyway, and the shockwave energy is not transferred to the target efficiently. By spreading the contact area for the explosive, more energy can be imparted from detonation into the target. (EDIT: This is why HESH is more effective at an angle because it spreads out over a larger area.) MP (multipurpose) are a form of heat round not primarily used for tanks but light anti vehicle/personelle/material uses instead of standard HE rounds, since the Abrams tank only carries 40 rounds of ammunition. MP rounds are less effective anti fortification rounds than HESH but MP are good enough for most purposes. The question is not how effective HESH is but do you need an anti-fortification round on an MBT which requires a specific rifiled gun and you have limited ammo space to work with? Generally no. But for specialised anti-fortification vehicles yes.

[@rolandlee6898]

@@Bordpie Im well aware of the principle. Im saying HE/MP rounds do the same in most cases. HESH was an interesting idea but has very little actual benefit. It will do nothing to any reasonable concrete structure that a HE/MP wouldnt do just as well. Any concrete structure intended to protect from heavy fire will be at least 1 meter thick. A HESH round exploding on the surface will do practically nothing. In fact a delayed impact HE will cause substantially more damage than HESH as it will penetrate into the wall and detonate within it. And it will actually produce superior spalling effects in this scenario as well (which is not a reliable factor btw, spalling decreases exponentially as the thickness of the target increases). There is no literature that would demonstrate that HESH is or was any more effective than standard HE at anything whatsoever. There is plenty of evidence to suggest programable fuzes on HE/MP is a far superior option

[@josepetersen7112]

@@rolandlee6898I’d expect HEP rounds to transfer a great deal more shock into what they strike due to the way the plastic explosive deforms onto the target. This should make it useful for knocking down structures or blowing large holes into light armor or concrete. IE, fortifications.while there are times that a timed warhead detonating inside is optimal, HEP, or HESH, can provide a means of actually demolishing fortifications that HE struggles to while still having effective terminal effects on people inside said fortifications. It is a niche role, as modern tanks shouldn’t be especially vulnerable to HEP, but it is real. It’s also a round that we really don’t understand all that well compared to say, HEAT munitions. At it’s prime, especially in Israel’s various wars, HESH proved quite effective.

[@rolandlee6898]

@@josepetersen7112 It wouldnt transfer more shock. Actually less. A HE with delay would be fully embedded in the wall before detonating, resulting in a higher contact surface area, more pressure and less material between the explosion and the other side of the barrier and thus higher change of breaking through. Pressure always goes the path of least resistance, an in the case of HESH thats away from the target, not into it, making you rely only on the shock front propagation to do damage, which is is not reliable and the effectiveness of that depends on the amount of explosive and properties of the material. The idea that spreading it thin makes it more effective is false. What squashing in HESH is for is to make direct contact with the surface, not to spread as thin as possible, thus allowing the shock front to directly transfer into the target. But that is a very unreliable, inefficient and inconsistent mechanism if you want to do damage. Simple illustration of the difference - putting explosives onto a rock, smear it as you please, and expecting the shock alone to break it or drilling a hole and putting it into the rock? Which one does more damage to the rock? You will quickly realize that the volume and geometry of the charge when putting it into the rock is a far more effective method, even in terms of shock transfer. HESH was a neat idea, but was never effective or better at anything, thats why it never was used by anyone that didnt use a British gun (which itself was trash as well). It made no sense. Brits stuck with it for the same reason they stick to other nonsensical things - national pride and straight up BSing themselves into acceptance and delusions of long gone grandeur. And when it comes to light armor, again, most HE rounds (and their fragmentation) will easily penetrate most light armor and/or cause behind armor effects on contact detonation, and/or cause significant damage to render the vehicle inoperable. As would HESH, but HE/MP is more versatile than HESH... so why would anyone use HESH? Well, they wouldnt - hence they didnt, anywhere, ever. FV4005 itself demonstrates to what levels of absurdity you had to go make it effective.

It takes out the turret with spalling, and though the driver avoids that, just the pressure takes care of the driver. HESH is truly fearsome.

[@gustavchambert7072]

What I would love to see is a simulation of the pressure effect of an APHE shell detonating inside a tank. As was shown in testing, the bursting charge does not significantly increase the damage from fragments, as the shrapnel travels along the same line as the hull/shell fragments. This would imply that the bursting charge was not very useful. And yet, all nations bar Britain used them throughout the war, despite such shells being more complex to produce, have less penetration and are more likely to shatter. My hypothesis is that the overpressure from even a small amount of HE-filler, such as is found in a 75mm shell, creates a very powerful pressure effect when detonated in an enclosed space like a tank compartment. I would guess it would be fatal for the crew, but even if is not, it would burst eardrum and cause concussion for sure, thus putting the tank out of action. It would be great to have that tested.

[@Treblaine]

I don't think it's that the charge isn't powerful, the issue is the charge has to be surrounded by such a thick mass of steel as only a steel shell of very high mass can still punch through armour. High explosives in fact impart a huge amount of energy to this mass of steel but because the mass of steel is so much greater than the mass of a thin walled howitzer shell the fragments are at a relatively low velocity but energy is still huge. Also the timing has to be REALLY good despite extreme deceleration, if it detonates too soon it spoils penetration, too late and it doesn't really increase the cone of fragmentation. The British had been in the fight the longest and had bitter experience of shells detonating too soon so spoiling penetration, I think this caused an institutional aversion that they just couldn't shake off. And they were forced to use shells without HE filler and found - in practice - that they seemed to work far better than theory would suggest. One reason for this is the success of fire on tanks is generally determined by how many shots it takes to ignite the tank's ammunition and overpressure (while very deadly to crews) is far less likely to ignite the ammunition. Also, the British war capacity was probably the most stressed of all the allied powers, it just did not have the size or scale the US or even Soviet production, so adding extra steps like a HE core for their anti-tank ammunition was a substantial cost for them. The USSR had production woes but it was far more an organisational challenge, the Brits just did not have much capacity and needed to cut every corner they could get away with cutting. A HE charge is nice to have, but you can just get away with not having it.

[@4buzerKomurcu]

I reckon that much explosive can even dislodge the turret depending on the impact position/angle.

[@_gungrave_6802]

While hesh from the FV4005 stage 2 is interesting you should do one for other british vehicles like the conquerer heavy tank and the mk 5 Centurion onwards which used a 105mm.

[@Paethgoat]

War Thunder should hire you to audit their simulations.

[@iatsd]

The part that is missing is the bit where the round lifts the entire turret up and backwards from the turret ring. Given that the Indians observed that with the 105mm against Pakistani M48's....

[@qaterdargon4041]

it would be cool to see the FV4005 against modern mbts

[@damarwirawan1348]

183 is an insane tank killer round. Even in simulation nor game

[@seta1773]

You can create simulation of steel helmet vs 9mm or bigger ?

[@alf3071]

can you test how an already penetrated turret with a hole does if it gets hit with a HE round? will it overpressure inside or is the hole too small to affect this?

[@ГусляизВаффендаля]

Wow, that very cool, but what the program?

[@squidwardfromua]

Would the crew be killed if it was an average high-explosive 183mm?

[@McGeistly]

This is so awesome!

[@stefanogalliano5634]

As we've seen already, in the times in which overpressure is fatal the shrapnel would have been too

[@Tango_Mango1]

I like how he points out, as long as the FV4005 hits a tank, it would die lmao.*Me using it in war thunder slapping people out of existence*

[@high-velocitymammal5030]

* hits the hull nose of a M48, knocking out both tracks and only mildly yellowing the barrel * 🥲🥲🥲🥲🥲

[@annonYk]

Yeah, BeSh ThEm

[@alexstrong4779]

let's have the main caliber of the battleship Iowa vs tank t-55

[@SergeiPetrov]

Please recalculate this hit into the tank turret, which is equipped with "Brezhnev's eyebrows".

[@Rob-vv5yn]

Amazing stuff appreciated

[@dinonuggiesguy4847]

Ngl if I were the crew inside I feel like it would hurt a lot

[@peasant8246]

Can you simulate something similar: 75mm M48 HE exploding after hitting the turret base, under the mantlet, of an early Panther tank? i wanna know if it will be enough to break the 16mm hull top plate and injure the driver.

[@georgeoconnor7861]

I think Big size of Ammo shells of HE is enough to Disable Tanks and its crew, Just like HESH but with a bit low on Explosion. This Hesh Simulations should add some real Picture inside the Tanks to compare the Test.

[@CetoFreakingKaiba]

Would it be possible to take into account interior modules or the existence of bulkheads and how they would influence overpressure? Or, since the roof is penetrated, would that be negligible?

[@raptango_na6199]

183mm HESH vs T54. My first thought..."that's not good!"
