4:05 Just to elaborate: the word "melt" was used more to paraphrase the act which actually happens, in which the copper lining does not actually melt, but ACTS as though it were a liquid (despite remaining below its melting point), due to the force that is being put upon it by the explosive charge, and the speed at which it deforms and penetrates the target material

[@30LayersOfKevlar]

Yes, but it's also not "cooling down" as you said at 7:09. Because it's not "superheated", it's in the state of superplasticity, due to pressure. Also I'm not sure where you got your info on ceramics in Chobham and Burlington.

[@jonny2954]

As far as i remember spaced armor of low thickness can actually increase shaped charge penetration in the main armor by giving the shaped charge more standoff.

[@drakko26]

As far as I understood it, the jet actually displaces and forces itself between the armor molecules. That's why it's veeery important where it actually detonates vs. the armor facing it's supposed to penetrate (hence being readily defeated by a simple cage/spaced armor layout).

[@jonny2954]

@@drakko26 Cage/slat and spaced armor don't work the same way. It's a common misconception that slat armor works by prematurely triggering the shaped charge warhead, because that would potentially even increase penetration in the main armor (as explained above). Slat armor works by sqashing/crushing the shaped charge warhead before it detonates. That's also why it isn't 100% safe, because if a warhead hits a bar head on, it's oof.

[@fi4re]

@@jonny2954 Thanks for explaining that! For the longest time, I've looked at the slats and thought "how could that possibly trigger a HEAT warhead? Wouldn't the tip of the warhead pass between the slats 95% of the time?"

1- shaped charges dont melt the armor they punch through it with the velocity f the explosively formed penitratore at like mach 9 or more 2- spaced armor may not only cause premature detonation but also normalisation at angals that are poorly suited to penetrating the main armor 3- mono block long penitratores do not bend well 4- ceramic reinforced metal armor can also significantly increase he effectiveness of a given thickness of conventional armor

[@MarcinP2]

The armor flows under extreme pressure. Same way as when metal is cold forged, sheet formed, rolled or pulled. The whole "burn trough" or "melt trough" is a close enough metaphor for a layman.

Wonderful co-work here, looking forward for some more of this Matt !

TOP 10 ANIME CROSSOVERS THAT NO ONE COULD HAVE PREDICTED.

[@whya2ndaccount]

Part of the difference between Soviet and NATO ammunition is due to the single piece NATO ammo (except the CR2) and its ability to include a longer penetrator. Soviet / Russian, two piece ammunition (required for their auto-loader systems), can't include that due to the projectile's size. Also NATO ammunition is more resource intensive as NATO can afford the resource / machining allocation.

8:15 When I was on the Syrian/ Iraqi border ive seen EFPs cut clean through Abrams armor (when they didnt have explosive reactive armor plating on) but ive seen bullet proof glass stop an EFP. When the humvee came back the driver side window was smoking on the outside but the inside the driver was okay. The inner glass was cracked from the heat but no penetration.

[@Verradonairun]

Very interesting. Are you sure that the failure of the EFP can't be attributed to the Humvee being slightly out of range?

[@bradleyanderson4315]

Then there is steel foam armor which acts sort of as a cross between rolled homogenous armor and spaced armor. It is three times as thick for the same weight and is particularly effective against heat and hesh while having at least as much effectiveness against apds as the same weight of rha. Very effective against mines when used as belly armor on vehicles.

[@Chaps_Jr]

I'm a bit late to this video, but I'd like to add an inconsequential bit of info. I was a nuclear Machinist Mate in the US Navy, so I had to learn every imaginable aspect of Uranium and its isotopes-- even on the theoretical quantum level. Uranium (U-92) is actually the most dense naturally-occurring metal that we can produce in significant quantities. It has a very unique atomic structure, unlike other metals. When most metals experience a large force (such as a bullet impacting armor), they deform into a mushroom shape as the material is pushed out of the way from the point of impact. However, when Uranium experiences the same force, it acts very differently. It tends to have a "sharpening" behavior, where the material that has expended its energy begins to chip away, allowing the remaining Uranium to continue on its path relatively unhindered. This helps the depleted Uranium penetrators retain their penetrative ability more efficiently, compared to more traditional steel or Tungsten penetrators. This, coupled with the extreme density of the metal, is what makes DU APFS-DS rounds so potent.

[@qbenalzaeen2052]

Another quality of DU is that it is pyrophoric ie. it ignitesspontaneously in air at low temperature

[@98integraGSR]

🤣🤣🤣 way to try to create a false equivalency, Seaman Shmuckatelli. I WENT to NNPTC. That school is a JOKE. It's nothing more than a minimum competency course to appease the DOE... and guess what? Ballistics ISN'T part of the curriculum. You want to brag about completing Prototype? Cool beans, nobody is stopping you... But going around KZbin trying to portray yourself as an expert in completely unrelated fields because you completed a fundamentally flawed community college Associate's-level crash course on BASIC chemistry and physics? That just makes you look like a pompous ass. The physics model you were taught? It doesn't even include reaction forces.

[@Chaps_Jr]

@@awashburn6944 I mean all you need to earn a degree or certificate at a state university is the minimum requirements. My point is, minimum competency is a flawed logic as an insult because it can be applied to nearly everything. How many times do we see complete idiots earning the same rewards as their hard-working counterparts?

[@Chaps_Jr]

@@awashburn6944 That's exactly my point. He claimed NNPTC is trash because it's "minimum competency", but that really means nothing. Entrance is based on intelligence levels rather than GPA, and the instructors all have many years of practical experience in the field. Also, I never claimed to be a nuclear physicist or engineer-- only that I have knowledge of Uranium isotopes. No idea what that guy's problem is, but he seems to have some things he needs to work out with himself.

Well don't underestimate the budget brutes. Denmark has just gathered money for update of 8 more Leopard 2's. Typical end of year budget cleaning. There are situations, where 8 such tanks can be mighty handy.

[@thomasborgsmidt9801]

Actually - and that is a technicality: When you don't spend all the money in a fiscal year - you can carry it over to next year. Only problem is: It tends to become a personal slush fund for generals - gets their mistresses promoted really fast too. So... there was a Chief of the Army that got himself an early retirement. What some don't really get is: A budget is supposed to be spend doing the job. If you do it better - well there might be room for expanding a programme, that was cut a bit to thin to pass the review process. So if you are smart as a commander you allways have a wishlist (It is Christmas - after all) - of sensible investments that make economic and operational sense. The airforce had 3 Challengers for North Atlantic Patrol - and VIP transport. So when they smashed an engine and the delivery time was somewhere in the distant future - VERY distant. The mechanics went on the internet and found a repossed Challenger in a remote place. The price for the engine was actually the same as for the whole aeroplan - VERY posh interior. So one of our navy ships picked the plane up - and the technicians got to overhaul it. So now there is actually 4 Challengers - and they avoid the cost of pulling the VIP interior in and out for the PM. And the PM has an Air Force 0.1 and the crews can absolve their training and do something usefull - plus it saves airline tickets.

Maraging steels (a portmanteau of "martensitic" and "aging") are steels (iron alloys) that are known for possessing superior strength and toughness without losing malleability, although they cannot hold a good cutting edge. Aging refers to the extended heat-treatment process.

[@markfryer9880]

On the subject of trigonometry as it relates to the penetrative capability of a round hitting the armour it is worth considering that the targeted tank is not always sitting in a level plane as witnessed by the game play video and the tanks out on the firing range. A tank as it is moving over terrain will pitch and roll in the positive and negative aspects often in combinations of both which will influence the force vectors being applied to the armour by any penetrators. What this all means is that while a theoretical presentation of a round hitting a target tank as it is presented when sitting on a horizontal surface, when it comes to hitting the real tank out on the real uneven ground of a battlefield just what the result will be is open to the variables of just how that tank is presented as a target and just where your round hits the tank.

[@phoboskittym8500]

A new technology called electric reactive armour (also termed electromagnetic reactive armour, or colloquially as electric armour) is in development. This armour is made up of two or more conductive plates separated by an air gap or by an insulating material, creating a high-power capacitor.[5][6][7][8][9] In operation, a high-voltage power source charges the armour. When an incoming body penetrates the plates, it closes the circuit to discharge the capacitor, dumping a great deal of energy into the penetrator, which may vaporize it or even turn it into a plasma, significantly diffusing the attack. It is not public knowledge whether this is supposed to function against both kinetic energy penetrators and shaped charge jets, or only the latter. This technology has not yet been introduced on any known operational platform. Another electromagnetic alternative to ERA uses layers of plates of electromagnetic metal with silicone spacers on alternate sides. The damage to the exterior of the armour passes electricity into the plates causing them to magnetically move together. As the process is completed at the speed of electricity the plates are moving when struck by the projectile causing the projectile energy to be deflected whilst the energy is also dissipated in parting the magnetically attracted plates.

That's actually what the super Pershing was pretty much it was a failed project that has only 2 total kills neither of which were king tigers

[@billwilson3609]

The Army wasn't interested in using the Super Pershing so Ordnance allowed Lt. Belton Cooper to add armor where he felt it needed more. Cooper complained during the war about the thin armor on US tanks so also grumbled the M26's. Cooper stacked layers on the hull glacis and added more to the front of the turret that added 5 tons of weight that made the tank nose heavy. Cooper was going to add more in the back to "balance" the tank but was told to stop since the engineers feared additional weight would ruin the transmission. It crawled off to the front where it hit 2 targets 1500 meters away that resembled tanks before being knocked out by a Panzer 4 that put a shot thru the side of the hull. The tank was last seen at a salvage yard waiting to be cut up for scrap.

In 1917 the British Royal Armouries tested captured German anti-tank weapons and ammunition versus the Harveyised rolled steel armour being used on the British and French tanks in WW1. Harveyised armour (1865) was a process of burying red hot steel plates in carbon granules and leaving it to cool over a long period of time, which allowed the carbon to be absorbed into the surfaces of the steel plates and increasing the hardness. On the downside it is very prone to spalling. It also cannot be drilled or punched so all holes have to be created before the process takes place. In 1921, when rolled and cast homogenous armour first appeared, they revisited these weapons again in tests for a comparison and measure of improvements in this armour protection advancement. (Vertical test targets at 100 yards range). Harveyised plate Rolled Homogenous plate Mauser 7.92mm. rifle AP K bullet: Up to 19mm. Up to 13mm. Mauser 13mm. anti-tank rifle AP bullet: Up to 30mm. Up to 21mm.

RHA gives more protection for the same thickness as WW1 era Harveyised armour (invented 1871). Modern day armour materials give considerable increases in protection compared to WW2 FHRHA. Progress is measured against what preceded an improvement.

In my time with the tankers, as a field artillery officer, they spent 90% of their time working on those iron chariots... Mid to late 1990s anyway. Sincerely, thank you for your service my brother-in-arms. [Assumes the ridged position of attention and salutes].

Very good video, thanks for increasing my tank neardyness.

Cumulative projectiles do not burn through armor, but penetrate, relying on the kinetic energy of the cumulative jet, which has a speed of about 10 kilometers per second, or hypersonic speed at the time of explosion.

We just need to equip all tanks with PlOt ArmOuR, then they will be invincible 😜

Here’s the thing I don’t get about penetration statistics. it can say”800 millilitres of penetration”.800 millilitres of what....Cheese?

I thought the thing was with the M1 was that the tank originally had the 105mm gun but by the time the Gulf War came around they had already refitted a good deal of them with the M256 120mm gun which is still used on it today.

If one is curious about ammo types, I recommend playing armored warfare, as there are many ammo types and there is a small animation for each shell type that demonstrates the penetration effect.

Glass plate armor was abandoned primarily because it required replacement of large sections to repair damage which could be difficult, time consuming and costly depending on access to and modularity of the armor sections. Other kinds of composite armor were somewhat easier to maintain. It still has the potential for practical use in smaller modular pieces if that was incorporated into some design. Fiberglass armor on the other hand has grown in popularity because of its particular characteristics being a reasonable trade off against most threats.

[@DavidFMayerPhD]

Fiberglass armor is superior to solid in that cracks are not propagated.

[@CZ350tuner]

It's interesting how, for the past 150 years or so, the maximum armour penetration of a gun and ammunition type was conducted on a test range, bearing in mind that they don't actually fire a shot into a very big and thick block of armour, dig the shot out and measure how far it went in. In 1921 the thickest rolled homogenous armour plate that could be manufactured was 8mm. thick yet range tests for the weapons around at the time quote thicker armour penetration maximums than that test target thicknesses available. This always baffled me for many years so I did some research on how penetration tests were conducted. Basic physics and mathematics come into play. Any projectile has 100% probably of penetrating air at a given range and only 1% probability of penetrating it's absolute maximum of a given material. Therefore if a number of projectiles are fired at a set thickness of material at the same range and half manage to penetrate then the thickness of the material must be exactly half the maximum thickness of the projectile's maximum capability under the same conditions. If only a quarter penetrated than the test target thickness must be only a quarter of the maximum thickness, etc. So if 100 test shots are scored on identically set up test targets and only 42 penetrate therefore the test target is 42% of the maximum capability of the projectile under the conditions of the test target set up. From this the absolute maximum can be extrapolated. In 1926 the British Royal Ordinance declared the first criteria for acceptance of a tank gun using this method of testing. This was based on the expected typical armour thickness of hostile AFVs that a British tank would be engaging in combat. For acceptance a test tank gun firing an armour piercing ammunition round had to have better than a 70% chance of a first round penetration (FRP) of a vertically set 8mm. thick face hardened rolled homogenous armoured target at a range of no less than 500 yards. Amongst the tank guns trialed were the Hotchkiss 57mm. L.40 6 Pounder (failed) and the Vickers 47mm. L.31 3 Pounder (accepted into service). In 1930 the acceptance criteria was changed to a better than 70% chance of FRP of 14mm. FHRHA @ 0 degrees at 500 yards, leading the 47mm. L.40 3 Pounder tank gun. In 1937 it was changed again to better than 70% chance of FRP of 25mm. FHRHA @ 0 degrees @ 500 yards. This lead to the rejection of 562,000 already manufactured (from 1934 to 1937) 2 Pounder APHE shells (as they failed to meet the new criteria) and delayed the acceptance of the 2 Pounder gun into the British Army. This also marked the moment when the British Army changed over to better performing solid shot. The obstelete APHE shells were used for training on ranges in the UK. (I own an unfired innert example of a 2 Pounder APHE shell complete with base fuse). This acceptance criteria has changed over time to reflect the possible AFV threats a British tank might engage in combat. Unfortunately during WW2 the Germans kept moving the goal posts so by the time something reached production and front line issue, it wasn't always quite up to the task on the battlefield versus the latest German panzers. The current acceptance criteria for a British Army MBT tank gun anti-tank round is a better than 70% FRP of 200mm. RHA @ 60 degrees @ 2,000 metres.

Andy Reid or they could just stack multiple layers of 8mm each 🤷🏻‍♂️

[@anchorbait6662]

Awesome. Thanks for posting that. If you have any links about this sort of thing plz add them. Cheers

[@MarcinP2]

@@StoneCoolds "or they could just stack multiple layers of 8mm each" That's a good point and might be the case but IIRC they knew from designing ship armor that this would not work. There were rule-of-thumb formulas fro applique armor and they knew the extra plate did not add the expected protection.

[@alifkazeryu8228]

Awesome comment sir.... if only I don't puke the moment I read physics and mathematics. SCIENCE IS A TOOL OF WHITE-SUPREMACIST PATRIARCHY!!!!! REEEEEE!!!!!

[@CZ350tuner]

@@StoneCoolds The problem with stacking multiple plates is that the impact force will tear them apart from the holding apparatus or even propel the holding apparatus. As a gun's exit muzzle velocity is not a constant, the single shot into a layered target such as you suggest might reflect a gun and projectile's true potential, given that the test round might be below parity / flawed in so many different ways. (The Chaos Mathematics are very much in force when it comes to propellants, muzzle velocities and structural integrity of projectiles). The Admiralty of the Royal Navy devised this test method during the Victorian period following the introduction of armoured warships.

[@Electric_Bagpipes]

if you didn't know, the ISS uses a form of spaced armor, basically a Kevlar layer that will help the micrometeoroid literally vaporize and then spread out and splash against the metal plate behind it (which is some form of aluminum or alloy). that's pretty good against something like a grain of sand moving at 20-30 km/s.

That would be NxRA. NERA is non energetic reactive armor.

@@jonny2954 They don't work differently according to the Patent. NxRA is just NERA with a special filler instead of plain rubber. But they are basically the same thing. C. Non-Explosive Reactive Armor (NxRA): [0011] Non-Explosive Reactive Armor provides a comparable efficiency to SLERA, comparable survivability to NERA (see below), and excellent multiple-hit capability against hollow charge warheads. NxRA's advantages over other reactive armor technologies are that it is totally passive and has substantially better efficiency than NERA.Energetic materials for NxRA are disclosed for example in [bla bla bla]. D. Non-Energetic Reactive Armor (NERA): [0012] Non-Energetic Reactive Armor has limited efficiency against hollow charges. NERA's advantage is that it is totally passive and thus provides excellent survivability and maximal multiple-hit capability, comparable to NxRA. [0013] It is an object of the present invention to provide a non-explosive energetic material suitable for NxRA which does not contain explosive material and fulfills its protective function (high efficiency and high survivability of the armor), whilst the non-explosive energetic material lowers the requirements of transportation and logistics according to various standards e.g. UN regulations as appearing in the Recommendations on the Transport of Dangerous Goods. [0014] It is a further object of the present invention to provide an armor element fitted for such an energetic material and where the armor is of comparable efficiency to SLERA and of comparable survivability to NERA.

[@jonny2954]

@@AverageJoe8686 The part you cited literally says nothing about how the armors work respectively. Yes, NxRA has a different filler, and this filler is changing how the armor behaves when hit, meaning how it works. In NERA, you have layers which 'transfer' energy from front plate to backplate -and this backplate is moving and damaging the SC jet or penetrator rod. In NERA armour this layer is passive, not active - it only transfer energy between metal layers. In NxRA, you have layers which are non explosive but reactive. This layer changes its volume during transfer of energy from first to second metal layer of the array -so BOTH thin metal plates start to move and both metal plates are damaging the SC jet or penetrator. The movement is much faster in NxRA.

The type of Tank Ammunition vs Tank Armor being used today and the case studies for success in the recent past wars, boils down to Crew Training, Crew Training, Crew Training, and more crew training. One can have the best tanks in the world with the best armor, and best penetrating ammunition, but it will depend on the soldiers, their plan, their live training and three minutes after the battle opens up, the blessings of God because the battle plan will most likely change drastically.
