    One small correction (at 03:00). HEAT shells, even though their name might suggest otherwise, do not melt through armor. The penetrating effect relies solely on the kinetic energy of the molten copper jet, not on its temparature.

    Somethings are wrong here. Dont wanna be that guy - but: 2:55 the metal inside a HEAT shell does not penetrate the armor by 'melting' through it, but rather than by the extreme speed (up to mach 25) it gains after the explosion right behind it. And it stays relatively cool - you can see that by examining the copper after beeing fired. Basicly a metal that was deformed whilst beeing cold would have a different crystal structure than one that was hot while beeing deformed.
    5:37 the Leopard 1 has no spaced armour. Tha A1 has only small plates on the turret, way less than the T26 or the Pz4H.

    • @theScottishKoala
      @theScottishKoala  5 років тому +1

      When saying "Leopard 1" this was including all variants. The A1, A2, A3, A4 AND A5 ALL had spaced armor, either as addon, or incorporated into the turret as an array.
      As far as shaped charges, most of them DO actually heat the lining significantly, just not to its own melting point. The word "melt" was used to paraphrase/simplify. Given the speed and pressure, the lining ACTS as though it were a liquid, and ACTS as though it were legitimately melting through the target

    • @MyDarkMe
      @MyDarkMe 5 років тому

      Well, as with everything it depends.
      First of all I interpreted it that way as if you were talking about the ingame Leo versions.
      But ofc, the later versions had the turret shield as well . So did the first 1895 after beeing refitted to the A1A1 standard - which had no spaced armor at all when coming from the lines.
      I digress, the point beeing that I wouldnt call the Leos a prime example of using spaced armor, because (1) the first design was without any at all and (2) even with the addons or the different turret, there is not much of it.
      Well sure, inevitably there is going to be heat transfer due to beeing in direct contact to the explosion. But the term significantly is somewhat vage. Plus it will heat up due to the friction with the armor.
      I see your point, but Im not happy with the term melting and "acts like a liquid", particularly in this context. Because the copper or whatever always retains its solid crystalline structure. Therefore it is a solid material.
      There is a significant difference between the material beeing quite a lot more elastic than usally and acting like a fluid.
      A fluid does not have the ability to keep its shape, whilst a deformed metal will.
      Due to a lack of words, I´d compare it to stamped sheet metal, which is much more similar to the actual process. The charge "stampes" the cone into a rod and propelles it at extreme speeds through the armor. With the side effects of friction between the rod and the armor, causing heat and junks of molten metal (which is enhanced by the blast of the explosion coming through the hole in the armor after penetration) to enter the tank as well.
      I know im beeing nitpicky right now, but inaccuracies like that, lead to people having the wrong ideas about stuff like this.

    • @hazoish7670
      @hazoish7670 5 років тому

      Koala is technically correct bu I find the term misleading, the way the copper jet moves so fast, it alters the properties of the armor kinds going it a melt effect but it’s purely kinetic. You notice heat has a bigger entry hold than the exit hole signifying that something is happening on the outsideand then the beam turns solid and punches through the rest. I find heat very interesting as of how it works.

    • @Warriorcat49
      @Warriorcat49 4 роки тому

      Fluid. The word you guys are all looking for is fluid. Look up super-plasticity. There is no melting action or even any semblance of melting action. The material is simply pushed out of the way.

    Night Firing exercises were the coolest. The mortar crews got training hanging illumination rounds to light the range as in actual combat. You would be duly impressed to see time-lapse photography of a Night Fire Exercise. Streaks of light across the sky from the mortar rounds and the tracers from the machine guns and the SABOT rounds from the main gun that made that " Splash" of sparks when the round strikes armor. In that mode, everything looks like multiple streaks of light in different colors. It is a striking effect.

    That T-05 laminated glass sandwich armor had a major problem in that when hit, it made a very large pit that covered a large area around the impact point with only a thin remaining layer of glass and the steel plate behind it; the front steel plate was torn off and most of the glass excavated. This meant the tank suddenly had a large vulnerable place ready for being penetrated with ease at the next shot by the enemy. And the large damaged region could not be repaired effectively. You had to go to many interlocking replaceable smaller replaceable plates, which was a radical concept back then. Eventually they had to "bite the bullet" and design armor like that, though made of stronger materials.

    8:20 Depleted uranium ablates into a hot sharp cone as it digs through material (instead of deforming into a mushroom shape like most other materials) and then it explodes into a white hot shower of sparks and shrapnel when it hits air on the other side of the armor (so you don't need secondary explosives onboard) which are what make depleted uranium ideal for armor piercing. Tungsten has a comparable density and good hardness properties, and political advantages, but uranium is so especially good at this one thing that we use it for AP rounds.

    some mistakes I could find.
    but it would be too much to put into a comment fully; so just a summary:
    1. HEAT does not melt through armor.
    2. spaced armor does not let HEAT cool down
    3. the NATO tanks may look "blocky" but they still have highly angled armor below that.
    so the challenger is not the only one ;)
    4. Challenger 1 actually didnt fight any 125mm armed tanks in the gulf wars and if it would have a hit to the hull would be its bitter end.
    5. loads on ammo that would need to much time for a YT comment.
    6. "nobody drives around with 600mm steel"
    WEEEELLL, the T-72 ural has a cast turret which is 400mm at its thinnest point
    7. ERA does not stop HEAT from getting fuzed, it cuts the copper jet into spaller pieces by forceing the 2 metal plates apart from another.
    it also does not slow APFSDS down, it only bends them using the same effect.
    8. it would be nice if NERA would have been explained a bit.
    otherwise it was a decent video I guess.

      Non-explosive reactive armor. And no, @Hazardous, NERA does not refer to any of those, except some NERAs could feasibly use plastics. Those types (ceramics, aramids, high density metals) simply resist incoming projectiles, and owe their protective values to high strength, hardness, density, etc. Reactive-type armors work by actively doing something to the projectile to try to disrupt it. NERA, specifically, is generally a thin steel plate, a thick slab of rubber (or similar material), backed by another thin steel plate. When it's hit, the rubber is deformed, like when you throw a bouncy-ball at the ground and it squishes, and this forces the two steel plates away from each other, hopefully deforming or disrupting the projectile in some way.

    Leo 2 arrowhead is a steel/rubber/steel non explosive reactive armour. The shock wave of an impact reflects off the back plate and causes the sandwiched rubber to bulge outward, forcing the steel plates apart on different trajectories. This expansion places asymmetric loads on the rod penetrator while feeding new material into the penetration, abrading it and causing the rod to bend or shatter, reducing the sectional density and ballistic shape it relies on to penetrate. The arrow head is not designed to cause the rod to tumble otherwise it would be a simple vertical panel placed around 800mm in front of the main armour. The extreme angle of the arrowhead shape is necessary to create the angular deflection to defeat long rods. The cavity is not filled because it doesn't need to be, and the shape does not create a shot strap because the steel sheet is thin and is designed to be penetrated so that the rod can be shattered by the shear forces created by the separation of the plates.

    @nathanokun8801 4 роки тому

    Long rod penetrators have an advantage in that they dissolve their nose as they penetrate, which makes what eventually get through the plate much smaller than the original projectiles. However, this dissolving has two interesting effects, in that this means that sloping and other forces on the nose that try to deflect the projectile, elongating its path and thus decreasing its front-to-back plate penetration, have less that they can "grip" to deflect the rest of the projectile behind the nose. This also applies to sloping the armor, so that, while the front-to-back effective thickness does go up do to sloping, the dissolving of the projectile nose and the similar dissolving of the armor in front of that nose really are no longer equivalent. The long rod is REAL metal that long, but the sloped plate only has its non-sloped REAL thickness with the sloping effect being more "virtual" to the forces working SIDEWAYS in the plate as the projectile forces its way through the plate (these are not "disintegrator ray guns" and the molten projectile mass at the nose and the molten armor material being displaced have to go somewhere with only a rather small part of the total being able to exit out the front of the plate during the time involved in penetrating that plate). Thus, the expansion of the hole is not just front-to-back but somewhat sideways, making a bigger hole than the original projectile width and, thus, the bulging a splitting open of the armor on the inside of the plate near the impact point can occur even though the projectile has still not penetrated the armor in that direction. The days where, with solid steel gun projectile, "what you see is what you get" are long gone...

    One very important detail is wrong here..
    Early Soviet 125mm APFSDS rounds were not designed to defeat NATO arrays that exist in the Leo-2 M1 etc. These arrays are a spaced NERA and NxRA design. Rounds like the BM-22 had terrible performance against simple spaced arrays, nothing said against complex arrays with multiple HHS plates and possible ceramic backing plate. Soviet intel was rather confident (and wrong ) that the next gen Nato tanks would have something like a Steel ceramic steel layout.
    To put it simply the yaw and fractures induced against the W core as it impacted the multi layer spaced array would cause it hit the back plate degraded, low energy, and at high angle.
    Mono-block DU rounds were vastly superior against just about every target expected to be encountered. The reasons the USSR didn't introduce them is because they couldn't.
    Working with DU is massively expensive, both in machine tools and dealing with contamination etc. Alloying it and forging it into long thin shapes with few defects is a very difficult process. The same goes for W long rods. The3b,-32 is very short, and 3bm-42 is multi core because a mono block core of sufficient length couldn't be constructed with enough yield strength or homogeneous dispersion of alloyed material. That it was better against some target arrays was more a happy circumstance of chance.
    Soviet tanks in the 1980s would have been in very serious trouble, not because the armor of the early M1s and Leo-2s was great against monoblock KE ( hint it wasn't the USA spent billions to solve this as they develop and tested their own DU mono block rounds ), but because their KE ammo was awful against the very specific armor arrays that Nato had introduced. The newer rounds were very uncommon until 1987-89 and by then barley adequate.

    A point of clarification on active defenses. Active defenses don't mean just jammers and the like but also include systems that are designed to actively destroy any incoming anti-tank munitions, missiles in particular. The Israeli designed Trophy system is one such example of an active defense system and the US has been experimenting with incorporating this, and similar, system into not only tanks but soft skinned vehicles too.
    One other thing, you should really try to do a colab with The Chieftain. While Matsimus is great, The Chieftain is an actual tanker, and (as you and others may know) was an M1 platoon commander during the Iraq War.

    Note the Germans did have APDS shells in WW2 but as they didn’t have tungsten they used it with ordinary steel. It still penetrated more but not too much hence its limited used. The problem with early APDS was due to uneven sabot separation the accuracy reduced.

    @johnba291972 4 роки тому

    I'm certainly no expert but when you talked about air spacing between armour it gave me a thought. I wonder if any R&D guys have thought, or tested even, putting highly compressed air between the armour in pockets so that the moment the projectile and explosives penetrated the first layer they would immediately encounter a very powerful force from the escaping compressed air pushing back at them in the opposite direction. Highly compressed gases can obviously be very powerful, in fact that is exactly what an explosion is. Possibly using a compressed gas like Hydrogen that would also ignite might give even better results, although in testing its quite possible the heat could result in having the opposite and unwanted effect of helping the shell or missile to penetrate easier/further. But I reckon the idea certainly is worth looking into and testing, if it hasn't been already tho obviously, lol. Well, its just a thought anyway.

    @vermilion7777 5 років тому

    Heats don't melt through the armor, that's a common misbelieve. They aren't as hot as most people believe, in fact, the copper spike doesn't even reaches the melting point of the copper itself and the penetration is solely kinetic. The detonation simply hasn't enought time to give large amounts of thermal energy to the penetrator. If that would be the case, simple HE rounds would turn any target into molten blobs.

      Usually APFSDS rods are segmented to handle reactive armor or plate arrays (which are kind of a reactive armor). The idea behind reactive armor is to break up the perpetrator or distort it so that it does not deliver its energy in a focused line into the armor. A segmented rod can sacrifice part of the tip section to punch through the ERA or plate array while the rear portion will hopefully be left relatively undisturbed to make contact with the final armor sections of the tank.

    Im certain Ive heard Matsimus say he was artillery but I could be mistaken. Also, HEAT rounds have been replaced by MPAT (Multi Purpose Anti Tank) rounds for M1 Abrams as service rounds and as far as I'm aware, a round is in development to replace that. Although MPAT is technically a HEAT round by nature, it has an 'Air' mode which is used primarily for helicopter engagements. It also incorporates a more aerodynamic bourellet than the HEAT round.

    APS does not hack into the enemy shell.... depending on the country of origin and depending on if its active or passive APS or not they usually launch a counter projectile against the incoming warhead or shell. To say they hack the enemy shell would thus imply the incoming warhead is electronic which not all are you cannot hack an APFSDS shell or a HEAT warhead not even a missile what you can do in the case of a missile however is disrupt their guidance system.

    • @theScottishKoala
      @theScottishKoala  5 років тому +3

      I did mean to dub over this bit post editing mentioning the "counter-projectile" idea, but what an APS like the Stora system on Russian AFV's does is muck with the SACLOS systems guiding missiles that use them. I've no idea if they can effect missiles like Hellfires or Javelins however

    • @Talishar

      @@theScottishKoala It's basically like a DIRCM, it shoots a highly concentrated amount energy to blind and overwhelm the warhead and basically block the command module from picking up the IR strobe on the missile, causing them operator to lose control of the missile. You still have to hope as the receiving vehicle that the missile didn't start on the correct path already before losing guidance as it'll just continue along it's flight path.
      The newer APS systems usually include small cannons around the vehicle to intercept incoming projectiles and disrupt them enough that they can't penetrate the armor anymore. For example, it can knock APFSDS rounds off alignment to their flight path causing them to hit at a far substandard angle. Due to combined arms operations though, a lot of western militaries have been reluctant for a while to use APS systems because as you can imagine, this system will maim/kill any infantry near that side of the vehicle. This is the same reason why the US and many other countries whose doctrine has infantry in close support of armor at times, stayed away from ERA. The ERA blowing up would cause harm to the infantry nearby supporting your vehicle. This is why if they did use ERA, it was usually on the upper facing surfaces. Soviet doctrine for much of its time had a very different operational doctrine where tanks were their own force and often independent of infantry so they didn't think of, or had to worry about fratricide from the ERA, so they plaster it everywhere.
