Hesh go boom Tank no go vroom Hesh impact simulation done simple

Oh brother……🤐

@number7red619 i mean its worth guessing its a 1/2 chance he could get it right

haha yes

🅱ESH

yeah, it really 🅱️ashes in the tank's armour.

What does the b stand for

@@Astro_Zed HESH is the BESH

Yes it would be worse, as things like optics, gun/turret drives, hatches, tracks etc not being included which would have been damaged. A simulation with an IS tank wouldnt have been able to show overpressure effects as there isnt much of an exposed hull roof.

Out of curiosity, how would spin affect the results? Thanks! Also hai SY, love you

@@A407RAC the more the plastic explosive is in contact with the armour the more damage it does. And spin makes it spread out more when it hits a target, and so does more damage

Godd ..boy

its not HESH,its 🅱️ *ESH*

I don’t really know, but I predict that ERA is highly effective against HESH. HESH mainly relies on physical contact with armor to transmit shockwave into thhe armor, and ERA might prematurely detonate the round, making it just about as effective as a normal HE round. Although, I could be wrong.

The shockwave from the 183 was so strong that it shattered the armour. If you are sitting in that turret, it would be even more mind-blowing.

@@kerbodynamicx472 literally mind-blowing.

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.

@@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.

@@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

@@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.

@@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.

Neither the Mk3 nor the Mk5 had a 105mm gun though, but i'm pretty sure the Israelis did have 105mm Centurions, just not sure which model it was.

@@rifraf276 you're right. Neither the Mk 3 nor the Mk 5 had 105mm guns. They had the 84mm 20 pounder gun. I think it was Centurion mk 10 which was armed with 105mm Royal Ordnance L7A1 gun. I am pretty sure there other variants with L7A1 gun too.

@@namespacestd131 mk 5/2 I believe is the first mark to have it.

I don't know about overpressure, but it's quite probable it would be a mobility kill if it hit close enough to the tracks

A near miss wouldn't even cause a concussion. Armor is great at resisting and dissipating high explosive pressure. HESH relies almost entirely on a perfect direct impact hit in order to function properly. If the impact is at a great angle, against the thick armor of the T-54, it wouldn't do anything more than leave a scruff mark. If the armor was thin (

@@johnhighway9397 its 17kg of RDX. You just need to get it in the right postcode! When I say near miss, I mean near. I don't mean dropping the shell 50 yards away, I mean it's about 2 or 3 feet away. I would imagine a thinly armoured vehicle like a BMP or a BTR70 would not take kindly to 17kg of exploding Playdough going off a couple of feet away.

@@samspeed6271 My good sir, this is not a generic high explosive shell, it's HESH. If you "miss" and hit the ground next to a tank, most of that shell's explosive energy will be directed into the earth. An infantryman might be killed if he's standing next to it, but a tank or APC won't even notice. We aren't putting 17kg of RDX into a box and detonating it. We are directing the explosion towards what the shell is hitting, similar to a shaped charge.

@@johnhighway9397 that is indeed true, a hesh round would direct most of the energy into the ground, however I believe that this shell in particular has enough residual energy to at least damage a light armored vehicle if close enough, like probably 1 meter away

See his S-tank simulations

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.

They test fired a few of these at a Conqueror tank and even hits that never defeated the armour pretty much wrecked all the equipment inside the vehicle!
