This animation discusses the difference in two ammunition types, HEAT and HESH. There are many resources on the subject here's an introduction: HESH: en.wikipedia.o... HEAT: en.wikipedia.o...
NEIN NEIN NEIN ! HEAT round do not MELT the copper liner. The copper liner is plastically deformed due to the intense pressure of the shockwave caused by detonating the explosive. That means a very high speed liner ( Tip and rear move at different velocities ). 7 km/s is a decent figure for the main body of the liner. Any metal armor it meets is plastically deformed due to intense pressure caused by the impacting liner. Yes, both get hot, but not hot enough to melt the armor.
You are correct that the copper liner does not melt but follows behind the high pressure jet. What is fascinating is at these speeds and temperatures, matter behaves differently. I found a good article that gets into more detail about the "jet" and "efp". defensepoliticsasia.com/heat-and-efp/ Thanks for the comment.
This is great info for those who dont want an overexplaination or complex physics calculations and crap. Simple and to the point on how it work physically without all the physics and whatnot behind it. Thats not a bad thing though, everyone starts from somewhere. We don't go to kindergarten and learn nuclear physics before naptime.
Solution 1 : MoAr ArMoR, but outside main armor. Solution 2 : Use explosion to defeat explosion. Solution 3 : Solution 1, but with fancy arcane materials. Solution 4 : Bolt some wire mesh outside of armor
0:45 Important to note is that US Army testing has shown the copper lance to not be molten, the high temps inside the vehicle come from friction of the penetration with the armor.
FirstDagger thank you! Was looking for a comment on this, if not for you I would have made one myself. Working in a tank museum I constantly have to explain that HEAT does NOT melt through armor. Thank you for putting this out there.
@@lukeskywalket2894 Its not molten, its in a superplastic state, it means that the metal has been forced into a liquid or plastic like state by the sheer force of the explosives, it punches through armour, not melts. However it is very hot and easily ignites both fuel, ammounition and flesh. en.wikipedia.org/wiki/Superplasticity
+Luke Skywalket Well, wait, I thought I’ve read that the reason composite armors are more resistant to HEAT ammunition is because the composite materials have much higher melting points than homogenous steel armor.
@@samiamrg7 AFAIK it's the different densities of the materials which disrupt the superplastic jet, since at the velocities it's moving at most things act like liquids, changing materials (especially at an angle) would cause the jet to dissipate much faster
fighterACE World of Tanks has a few videos that explain how each tank shell works and how armor, angling, and distance impacts their penetration values.
@@thefogel6049 ain't fascist. I'm just not naive. Even if we've achieved world peace, it's just a matter of time someone's gonna break a war for whatever reason.
Its weird how HESH rounds work, just looking at the impact you'd think it hardly did anything, just a little mushed in dimple, but the shock wave formed throughout the armor shoots a little puck of steel from the inside at hypervelocity throughout the inside of the tank, with lots of extra little shotgun bits to boot. Works on the principle of those ball bearing kinetic sculpture things, where the ball bearings in a line pass the energy from the swing of one bearing through several others without moving them, and on to the last bearing in the line. Just this time the ball bearings are 6" of steel armor and the dropped bearing is several pounds of very brisant high explosive.🤣
If the fragments from the shell's effect doesn't kill you, the sheer concussion from the explosive mass will do your ears or brain to mush, scary round, HESH.
@@patrylec1510 HESH rounds are not practically anymore these days. They pretty much lose their effect against modern armor with layers of different materials. On top a lot modern tanks have spall liner plates inside, means if a HESH hits you and the effect penetrates the armor, all spalls/splinters are absorbed by these plates.
9th Blood and Fire HESH is used mainly these days as a general purpose round by the British Army Challenger 2s. If something is that heavily armoured as you describe, then simply fire a APFSDS round instead.
@@9thbloodandfire508 The only thing HESH is not effective against these days is an MBT with modern armour. HESH is still perfectly effective against less well armoured vehicles, such as APC's and IFV's, Buildings, fortifications, legacy MBT's with homogenous rolled steel armour, and pretty much anything else either the tank crew or the infantry it is supporting want dealt with. Stating HESH is not practical anymore is idiocy, other tanks are the least common targets of tanks. Tanks mostly shoot at things the infantry they are supporting want killed, not other tanks. HESH is still perfectly good at killing those kinds of targets, so much so that the High Explosive rounds carried by Challenger II's are HESH. For a modern tank the crew would select APFSDS over HESH. They DO carry some you know, Challenger II has an 82 round ammunition capacity....
That was probably one of the best videos I’ve ever watched. Straight to the point, talks about ammo type and armour, research behind development and how the ammunition works 10/10 this has earned my like
Premium quality video right there, short and concise, no bullshit, fillers or whatsoever, great animation, presentation and overall perfect for the curious individual like most people are on CZcams, no unnecessary details, straight to the essential but gives you the means to dig up more on the internet if you wish about said round or armor (or subject). You got a sub!
basically the shell is made of 2 parts: the core and the casing the casing is usually a softer metal like alluminum meanwhile the core is made of somethin like tungsten the casing acts like a sabot since the core is too small to fit in the barrel on its own. casing hits tank, deforms and the core goes through main issue is that apcr barely creates any shrapnel; post pen effects are pretty much none apart from the core itself. also they were very expensive to make so they just gave up on them if i missed something/misinformed ill love to hear it in a response to this comment

Contrary to a widespread misconception (possibly resulting from the acronym HEAT) the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature. And slat armour doesn't rely on causing premature detonation, but on deforming the fuse. Premature detonation would actually improve the penetration of the shaped charge in many situations.
Beautiful video-want to see more. Common misconception is that HEAT rounds “burn” through enemy armor, but it is actually pressure that causes penetration
They were only talking about warhead anyway not its means of delivery. You don't see anyone complaining that one is a two piece ammunition and the other uses a cartridges.
like mot others down here i thank you for making a finely detailed explanation for how each of them work with nice animations and kept it within one minute. kudos!
That's a good suggestion, I will give that some thought. Is there a particular part you find interesting? How the recoiless system works? It's interesting how gunners are not supposed to fire move than 6 a day due to over-pressure shockwaves!
@@H1MIN Yes, I'm interesting how the recoilless system works. In other recoilless systems like RPG I can imagine that. But with the Carl Gustav M3 / M4 I'm having trouble seeing it 100% right. I have other suggestions: 1. The AT4-CS (this uses saltwater as a countermass for the back balst and so the rocket can be shot in small spaces). 2. When the tow missile detonates directly over a target (tank), it will be destroyed. How? I love your work and the animation is wonderful. It helps us to imagine how things work, and let us rightly understand it I admire your work and appreciate it very much. thx
@@ali012alshair Not sure what is confusing, it allows gas pressure to vent backwards so you get equal forces moving backwards and forwards, cancelling eachother out. All AT4s are recoilless rifles, they do not fire a rocket. However the grenade can be equipped with a rocket booster to increase range and accuracy. Modern TOWs and other weapons like the NLAW simply has a (or multiple, like the Bofors BILL 2) HEAT warheads directed downwards. They use proximity fuses to detonate rather than impact.
first the shape charge DONT form molten metal it is a cold formed spike on wikipedia exists a good article about shape charges and how they work second inform yourself first thank you
Oh those plucky "Brits" using silly little rounds while the rest of the NATO were poisoning their troops from DUP. The problem with armchair engineers is that most don't research the subject enough.... Yes, it is said that HESH hits the target and bits of metal go whizzing around the inside of the tank. Spall liners stop this, ceramic Armour (ours) stops this, thicker Armour stops this... Challengers have all this... but the only blue on blue that wasn't Abrams bouncing DUP's off Challengers, saw a single HESH take out another Challenger. Ask a British Gunner why they like HESH, you will only get a knowing smile. Remember this little Isle helped to test US Air Defenses in the 70's with it's V-Force, shutting down Military Radar/Command & Control/Communications... Then simulated bombing Norad, Cities and a number of US Airbases devoid of fighters that were frantically trying to find the V-Force. Still unchallenged the Victors, Viscounts and Vulcan's flew over the White House in "V" formation just to give US Generals a hint to their position.
The British Engineer yes, but what has the UK achieved recently? You guys must be so disappointed with the massive slide into obscurity you have managed in the current world. From global empire to bankrupt spit of land in 75 years.
Tolles Video, und äußerst Interessant und Informativ ❤ herzlichen Dank dafür HESH zu deutsch, Quätschkopf Geschoss, und HEAT zu deutsch, Hohlladungs Geschoss, schade das nicht noch die Panzersprenggranate von früher erwähnt wurde.
I'm fortunate enough to have fired both in my Army career. 120mm HEAT-T, MPAT, MPAT-OR and 105mm HEP and HEAT. In US Service, HESH is known as HEP (High Explosive Plastic), and is a phenomenal wall and obstacle breacher.
Slat armor primary goal is not to cause premature detonation, but to break the piezoelectric fuse of the HEAT round used (most usually found on RPG grenades) or to change the angle at which the round hits the armor.
...we called HESH HEP..High Explosive Plastic...about 4 months before I got to my unit in Germany on 8 Dec '71 - they had a HEP round detonate in the main gun tube (Grafenwohr) it split the barrel in two - just forward of the bore evacuator...they had an enlargement of the photo on the wall of th3e battalion S3 (4/35 Armor)...no more HEP was to be used at all in practice in USAREUR...
The interesting thing alot of people seem to miss interperate is Heat ironicly doesn't use the heat of the molten metal to penetrate but rather the pressure.
Not mentioned in the video, but the material that break off from HESH, is called spalling and it happen with other rounds just not as effectively. Now hesh isn't really used because tank are now lined with anti spall coutings.
Also remember that it is mostly used against fortifications, pillboxes, bunkers, and reinforced concrete walls, pretty much anything that’s not a tank.
HESH (called "High Explosive Plastic" (HEP) in the US Army) has replaced most of the old nose-fuzed HE shells in tanks and anti-fortification close-range weapons due to its tremendous ability to blow HUGE holes in earth, concrete, and similar materials -- its anti-armor function requires a solid steel plate up to 1.7 times the diameter of the of the shell to work (thicker plates if the metal is too brittle) and can tear apart steel plates up to about half of the projectile diameter, making holes like it dos in concrete. However, if anything interrupts the shockwave moving through the material, such as spaced or laminated plates, the effect will be reduced considerably, though the tearing ability against thin steel is not affected as much by narrow spaces, where it reverts back to the brute force of the powerful explosive (C-4 "plastique") used in these shells. An all-round good anti-anything shell.
Small note, HEAT-shells do not produce a stream of "molten" metal. The copper-, or today, alloy-cone is formed by the explosive-force into a rod, which perforates the armour not by heat, but by the sheer speed it is being pushed by the explosive, depending on shell-type and conditions, up to mach 25. The armour and internal components do get melted, however this is a side-effect of the penetrator-rod perforating the armour.
the video is titled hesh *vs* heat which made me hope for a comparrison between the two but this was basically just a simplefied explanation on the two ammo types with no overarching points attached
They're not comparable. HEAT is useless against structures like concrete walls which are easily turned to dust by HESH. HESH is useless against hardened armour of tanks where HEAT can easily turn their insides into a bloody mist.
NEIN NEIN NEIN ! HEAT round do not MELT the copper liner. The copper liner is plastically deformed due to the intense pressure of the shockwave caused by detonating the explosive. That means a very high speed liner ( Tip and rear move at different velocities ). 7 km/s is a decent figure for the main body of the liner.
Any metal armor it meets is plastically deformed due to intense pressure caused by the impacting liner.
Yes, both get hot, but not hot enough to melt the armor.
You are correct that the copper liner does not melt but follows behind the high pressure jet. What is fascinating is at these speeds and temperatures, matter behaves differently. I found a good article that gets into more detail about the "jet" and "efp".

Modern TOWs and other weapons like the NLAW simply has a (or multiple, like the Bofors BILL 2) HEAT warheads directed downwards. They use proximity fuses to detonate rather than impact.

...we called HESH HEP..High Explosive Plastic...about 4 months before I got to my unit in Germany on 8 Dec '71 - they had a HEP round detonate in the main gun tube (Grafenwohr) it split the barrel in two - just forward of the bore evacuator...they had an enlargement of the photo on the wall of th3e battalion S3 (4/35 Armor)...no more HEP was to be used at all in practice in USAREUR...
Very interesting comment, that must have been a shock to the turret crew! Thank you for your service!
Wow ! I found really good content today. ....thanks to you and CZcams! ! I subscribed
The interesting thing alot of people seem to miss interperate is Heat ironicly doesn't use the heat of the molten metal to penetrate but rather the pressure.
I still can’t believe that high explosive squash head is a real acronym
Brief and clear. Did tell what is the difference.
extremely well made video, those animations are spot on. thx
I like this video, short and well edited and those animations and models!! so much quality
Not mentioned in the video, but the material that break off from HESH, is called spalling and it happen with other rounds just not as effectively. Now hesh isn't really used because tank are now lined with anti spall coutings.
Also remember that it is mostly used against fortifications, pillboxes, bunkers, and reinforced concrete walls, pretty much anything that’s not a tank.
The animation quality is orgasmic. Instant subscribe!
Lol
HESH (called "High Explosive Plastic" (HEP) in the US Army) has replaced most of the old nose-fuzed HE shells in tanks and anti-fortification close-range weapons due to its tremendous ability to blow HUGE holes in earth, concrete, and similar materials -- its anti-armor function requires a solid steel plate up to 1.7 times the diameter of the of the shell to work (thicker plates if the metal is too brittle) and can tear apart steel plates up to about half of the projectile diameter, making holes like it dos in concrete. However, if anything interrupts the shockwave moving through the material, such as spaced or laminated plates, the effect will be reduced considerably, though the tearing ability against thin steel is not affected as much by narrow spaces, where it reverts back to the brute force of the powerful explosive (C-4 "plastique") used in these shells. An all-round good anti-anything shell.
Small note, HEAT-shells do not produce a stream of "molten" metal. The copper-, or today, alloy-cone is formed by the explosive-force into a rod, which perforates the armour not by heat, but by the sheer speed it is being pushed by the explosive, depending on shell-type and conditions, up to mach 25. The armour and internal components do get melted, however this is a side-effect of the penetrator-rod perforating the armour.
The Physics in this video is on point.
Straight to the point. Perfect! :P
the video is titled hesh *vs* heat which made me hope for a comparrison between the two but this was basically just a simplefied explanation on the two ammo types with no overarching points attached
They're not comparable. HEAT is useless against structures like concrete walls which are easily turned to dust by HESH.
HESH is useless against hardened armour of tanks where HEAT can easily turn their insides into a bloody mist.
These animations are really good for visualizing what the ammo types do. Very well done.
Direct to the point. I like it.
Quick, to the point and no bull shit, good video.
although these videos are more than 1 minute, but it deserves watching
Your video is great, concise but it contains all I need to know! U r great. Thanks!
Simple and plain. Thank you
In a Minute . . . what a concept . . . Love it!!!
Excellent explanation.
This video was beautifully made, more of this please!
