The first weapon used in combat to fire HESH was the Petard Mortar mounted on the Churchill AVRE during WW2 versus bunkers & fortifications. The next vehicle to use HESH in combat was the 95mm. 32 Pounder Howitzer equipped Centaur CS cruiser tank in 1945.

Would it be possible to test the effect of obstacles in the path of the shell, like spaced or ERA, and my personal favorite playing WT: Hitting the track splash guard like on an IS 2 for example, in game it nullifies HESH but I wonder if it would split the shell as it's so thin and let it reach the armour anyways.

ERA and Spaced armour would be very interesting and I may do it in the future but smaller obstacles are challenging as the fuse sensitivity of the HESH round is unknown; in my model the shell detonates at a certain time that I decide, so I wouldnt know when to say it detonates if it passes through thin objects like a track guard.

yeah, in reality the back of the shell is made up of the fuse and the tracers so isnt just a solid lump of metal; it was just modelled as such for a simplification. The blast would likely break it apart a bit in reality but probably ouldnt fling it back as the blast mostly dissipates out of the sides.

Wouldnt you have more taper on the shell walls? This would create a better shape for the charge and direct more energy towards the armour instead of having most of the force blast out the sides of the shell.

For education purpose you need to be licensed like professional by any gov institution, and on specific field, and during education processes you know exactly what is your position, without disclosing things which are protected by law, knowing what can teach and what you can not teach. But in USA using the word "for education purpose" too much things peoples learn, including things which are not true, also, "teaching" others different things which NOT everyone need to know. Example: US citizens have too much weapons in hands of civil population, except small arms they have heavy MBT's, attack airplanes, and more. Soon or later USA gov will be at war with own people, then peoples using such information for weakens of any weapon which gov can use, will bring more catastrophic loss to gov. We, in EU have more strict laws than US, which even if you ask "which type of gun policeman use?" gov can send some dudes at your door and ask you "what is the purpose of such question?" And, if you dont have exact answer except saying "curiosity" then gov will remain curious about you for entire your life, and time to time you can have 50 spec ops dudes at your door ordering you to sit down, and watch how they control the entire house, doesn't mater, during sex, during party, during the most important moment in your life, they will come and make things wool. Why? Because they need to know "your curiosity". Sorry for mistakes, im on phone. edit: regulating writing errors and adding this below. Can you imagine what destruction such peoples are bringing to gov when they using the word "for education purpose" they are sharing like example, the weakness of bulletproof west which policeman use?! Bad guys use such info to buy more powerful guns and penetrate the west of policeman, which is happening today in USA. Abrams tank is in use on different country's outside USA. Example, S.Arabia is at war with Yemen, and because of peoples sharing such infos, the enemy know exactly what to use against what, without need to capture any tank and test it against different weapons, which will make things much more difficult. Today, things can be shared easy online, even peoples give important infos for free, just to earn more clicks on KZread. This brings devastation loss to gov. During WW2 if an weapon was captured by enemy then such weapon became obsolete instantly, or at least until enemy finds an solution to counter such weapon. Leopard tanks are produced to counter enemy in front side, like tanks against tanks. The way of war changed last time, especially last 20 years when modern country's does not need tanks but ATGM will do the job just like tanks. Personally, i disagree using MBT tanks during war. Why? - production is expensive, - production of MBT's need more that 1 factory, which during war time such factory's will be destroyed during first days of war, - maintenance is expensive, - are obsolete in front of ATGM, - MBT's reached the highest weight which can be tolerated in nature using steel, but shaped charge still can be manufactured even bigger than modern 130mm, which some country's use 300mm shaped charge like anti tank mine, which can penetrate the entire tank from one side to other one. Shaped charge can be produced even bigger and bigger if is needed. - there are tooo much weapons produced until now and with main purpose to destroy tanks, all starting by the word "Anti Tank" such or that, - losing over 50% of tanks during war, automatically means capitulation, but Afghanistan lost over 20000 soldiers and are not considered losers, but victory over West. - Me personally, i cant understand the sense producing tanks still today, when a $10k missile can blow up ANY tank which cost over 10 millions ore more... - mounting an 120mm AT gun in armored car example, with 20mm steel plates just to be enough to carry the gun, i think is enough, than producing tanks too heavy. In both hands, it is armored car, or apc, or tank, will blow up soon or later. Russia produce armored cars with 12 ATGM's (ready to fire), are they stupid? I think they are smarter than Britain. - airplane mounted AT missiles will blow up any modern tank, even over 8km away, - Tanks no more can be used on street fighting, simply, they can not withstand an attack from all sides where enemy can use rpg's or ATGM's from high buildings, - Tanks no more can be used to face tanks or any kind of threat, except to fight against APC's or infantry, even then, tanks can be destroyed easy by atgm. - starting from 1980, especially from y 2000, simply all tanks are useless today. Serbia shot down B-2 or F-117 airplane (i cant remember which one) when still was undisclosed project by USA gov. Serbs were asked: But it was a stealth airplane, how you done that? Serbs: I dont know what "stealth" mean, we just launched 2 missiles and airplane catches fire instantly. (by the way, im not serbian lol) Same with tanks, no more is important the armor of tanks, but the tactic how they are used ,and which purpose.

So the failure type of both the projectile and plate were changed, to reduce computational time and allow HESH to work respecively, this means cracking wont show on the rear of the projectile like my previous HE video. The rear of the shell is much less effected than the previous HE video as the walls of this projectile are thinner, allowing the explosive gasses to expand sideways, putting less pressure on the rear. As for the cleaner visuals, that was just me messing with the results file (hiding unecessary things and not always showing the stress plot) but it is the same engineering software (abaqus)

In the mid to late 1800's, the British Royal Navy developed a HESH projectile called the Copper Head to deal with the then new iron clad warships. The shell was a solid iron cylindrical body and capped with a domed gunpowder filled copper head. On impact the copper head would compress, detonating the gunpowder within it. The explosion would generate a wracking shock wave, which would pass through the wrought iron armour of the target ship, causing spalling on the far side. When late 1800's ironclad warships started having laminated armour with Oak, Mahogany & Iron Wood (Lignum Vitae), Copper Head shells became obstelete.

Now the British army are going to go the same way with their next tank, I don't know why or what's best for what purposes. HESH could be quite good fired from an AT gun or light artillery, especially because it's good against a bunkers and earthworks.

Otherwise, High Explosive Anti Tank works similarly, except instead of there being a projectile, the hollow cavity is lined with copper, and on detonation, the explosive forms the copper into what is essentially a liquid beam, moving at insane velocities, which has the capacity to go through a lot of armor.

A thought occurred What would happened if you had a tungsten rod in the back part of the shell? Or even at the front

Well the goal of HESH is not for the round to pen the target, so in the front wont make sense. The tungsten in the back might do something for the shrapneling if it pens the target. Goal of HESH is the more armor the target has the more shrapnel gos flying and bouncing inside the target. That's why most tanks these days have different layered armor or composite armor to stop these kinda of rounds.

@@timiaus yeah thats why i was saying have a two part round First the tungsten dents or puts a small hole creating a cavity for the force to concentrate Then the squash head detonates I suppose there is probably a good reason why this doesnt work and i just cant visualize it in my head yet

Arguably more scary than an m1 Abrams sabot making your vehicle shred you This makes your hull liable to Kurt cobain you

Try 105 hesh vs 200mm plate

I would NOT like to be the poor foot soldier standing next to that thing when it explodes

Wasn't HESH created to combat angled 120+mm armor ie specifically IS-3?

It existed for quite a while before that, and offered improved effectiveness against concrete structures and armoured vehicles than standard HE (although worse against infantry). When the IS3 came about HESH was used on the fv4005 which WAS specifically designed to counter heavy targets like it

@@SYsimulations IS-3 "came about" in 1944 and was shown on parade in 1945. HESH was created based on analysis of effetto pronto rounds post war if I'm correct.
