      Awsome vid one thing you forgot its been around for a while now is a good example is the Isreali Active Protection system Trophy or for short APS. It can detect incoming rounds from RPGs and ATGM and destroy them. Even improved systems in development are claiming they will do the same for incoming APFSDS rounds.

    Angled armour pre-dated the T-34 by a long way and its advantages were well understood thanks to naval design dating back to the 19th century. I think the reason for boxy tanks was part volumetric, part constructional and part metalergical.
    Likewise, while electric arc welding has existed since about 1801, armour plate isn't anywhere near as easy to weld as your average mild steel & was prone to cracking or weak joints. Indeed the internal stresses would often cause welds to crack when a plate was struck by a round. This was the reason why Germany favoured interlocking welded plates.

      British tanks generally favoured rivets as all the good welders were concentrated on shipbuilding and its just easier to rivet than weld. The russians insisted on welding the T34 regardless of the factory workers competence and some times the armour would stop the round but the welds would crack. Apparently the armour was often overhardened which would lead to spalling on the inside, which was lethal to the crew.

      @@SlappyTheElf Incorrect. Soviets were one of the first to develop "submerged arc welding" which allowed them to weld. Riveting is far inferior to welding but if you do not have the tech... you rivet. Soviets simply were more technologically advanced the the British.
      The reason weld jobs on T-34 were sloppy is simply the need to make them fast.

      @MrNigzy23 ปีที่แล้ว +14

      ​@@tomk3732 Incorrect. SAW can only weld in horizontal and flat planes. It is not ideal for use in armour plates.
      SAW can also not be used on alloy metals, it is mainly limited to being used only nickel and nickel alloys.
      SAW is also hugely bulky and overly expensive compared to SMAW, it is not practical for welding armour plate.
      SAW is not used in military applications and is mainly used for the construction of civilian infrastructure like pipes.
      The fact you think that SAW and SMAW are not the same is also funny, it is. It's literally one difference in being that the electrode is submerged or not.
      Oh, SAW is also not portable, hence why you typically see this process in small automated processes, confined to one area like production lines.
      I mean, why even bring SAW up? It is not applicable in anything here at all unless you want to build a civvie car or lay some pipes.
      Soviet Russia was late to the welding game. Britain had been welding since the turn of the century, but just as the dude said, most welders were hogged by the Royal Navy because that is the oldest and most prestigious branch of the Military. It received more funding than the Army several times over, it was a very lucrative career being a welder in the Navy.

You aren’t going to dodge a sabot round coming in at 1200+ meters/s.

      There was just no reasonable amount of armor that you could add on a tank, that would protect you from 100mm and 115mm HEAT rounds, without turning into a mobile pillbox like T-28 Assault Gun.
      Chieftain (60t weight) is 15t heavier than Leopard 1 and about as protected vs HEAT and AP ammunition of the late 60´s early 70´s as leopard 1. The sacrifice Chieftain had to make for its irrelevant armor was a 20km/h lower topspeed, atrocious terrain mobility and a 35-40% failure rate under peace conditions for the drivetrain and engine.

      The problem was the extremely thin turrets as seen on the Leo2 which badly needs more armour on the turret sides.
      Very few CVR(T) were actually hit by the enemy, their speed was their protection!
      Very hard to hit a moving target even with modern computers, most ranges have movers from left to right, once the little buggers start zig zagging it is almost down to luck.

      Rocket Propelled Grenade wouldn't even be correct anyways, since most people don't know the RPG-7 is actually a recoiless launcher. While it has a Rocket sustainer motor/booster, that's just to extend the range a bit and help it stay level, the main propulsion or "Launch Force" is still a powder charge with half vented out the back counteracting recoil like you'd see in a Panzerfaust, AT-4, or Carl Gustav.
      Grenade can also mean plenty of things and is basically just small explosive, for instance submuntions from a cluster bomb are commonly referred to as grenades, and you can have "Grenade" rounds for a cannon which is just what some places call HE/HEF/HEI/Etc.

    I watched a bunch of old German army training videos for tankers a while ago and one of the most interesting things about those videos I noticed was that they didn't even mention the tank's armor once in them.
    They still instruct the drivers to point the front of the tank at the enemy, but not because the armor is thickest there, but to make the tank's silhouette as small as possible, not so much to be harder to hit, but for minimum visibility.
    They really seem to treat the armor as an afterthought.
    The general gist or mentality is that relying on armor for your safety is like relying on your car's airbag and seat belt to get you from A to B safely, instead of your driving skills.
    Armor is just a last ditch hail Mary safety feature that may help, may not after everything else has failed.

    One of the things I've always been interested in with regards to armour is how it reacts to repeated hits. More in the example of cast or homogenous steel armour. Repeated hits by shells that can't penetrate an armour of a given value. Would eventually get through is what I am thinking. I've seen first hand WW2 tanks that have had non penetrating hits and the damage is noteworthy. It looked like the steel had been melted and pushed armour aside.

    • @pyro1047
      @pyro1047 ปีที่แล้ว +4

      An important part of this is penetration absorption, you want the face hardened to be stronger and if possible shatter shells, but you also want the back of the plate softer to sort of absorb the force I guess.
      With a soft back it might bend, dent, or deform easier, but it's less likely to crack or spall as bad as fully hardened armor.
      This was why Soviet and German tanks spalled and cracked so bad, the German armor was too face hardened and they lacked the supplies to divert alloys for tanks, meanwhile the Soviets just over hardened the entire plate.
      US Warships had a similar problem, things like the turret face armor were hardened too deep actually reducing protection over if they had the same thickness with shallower hardening. They did this on accident, trying to increase protection but unknowingly reducing it.
      Softer armor was also actually an advantage on the M4 Sherman though I don't rememberthe exact reason, something like while it's less likely to shatter a shell it's more likely to "gouge out" the armor and bounce.

      @kemarisite ปีที่แล้ว +4

      In addition to the below, you asked about RHA, which is rolled homogenous armor and is in contrast with face-hardened armor. RHA is basically a billet of armor alloy steel that is then rolled down to a particular thickness, which also causes the billet to spread laterally. The rolling process both gets the steel down to the specified thickness and dimensions, from which excess can be trimmed and the RHA plate welded into place on the frame, and work hardens the steel making it harder and more resistant to penetration but also more brittle. In contrast, face-hardened armor takes a similar plate of armor steel alloy and heats the plate up to fairly high temperature, then quickly quenches the outer face of the plate to cool it down. This makes the surface very hard to a depth of between 1/4 and 2/3 of the thickness of the plate (depending on the manufacturer and purpose), while the back of the plate is more ductile and better able to absorb the shock of an impact without shattering or having fragments spall off the back. RHA is common for tanks, which are mass produced, but face-hardened armor is better overall if more difficult and expensive to produce, so it would be used for more limited production tanks and for warship armor.

      @@kemarisite From what I read elsewhere, face hardend armour was initialy considerd superior, as it could cause impacting AP shells to shatter.

      @@Bird_Dog00 that could very well play a roll with tank armor, but there is a lot of overlap with warship armor. Even with a suitable cap on the shell, face hardened armor plate was typical for warship armor right up to the time (after WW2) when warships gave up on exterior armor entirely as a wasted weight. The Iowa class battleships used Class A armor plate, which is face hardened, on the main belt, barbettes, and turret sides and rear, with Class B (non face-hardened) armor plate on the turret faces, deck, and citadel because of some unique US Navy assumptions about the kind of combat they would be getting involved in and the weapons that would be used.

If you are trying to protect 1 vertical meter of height, if you tilt the armor 45 degrees, one meter's height of armor won't reach. You'll need a plate that is 1.41 meters long. If your "roof" was much thinner (lighter) material, you may definitely end up increasing weight by slanting the plate.

    A lot of the up-armoring on the Shermans in WW2 was pretty much totally ineffective against armor-piercing gun projectiles (and probably made the armor _less_ effective against them), but it was never intended to stop those. It was just there to make shaped-charge rounds from Panzerfausts and Panzerschrecks detonate prematurely. A shaped charge needs to detonate at just the right distance from the target as possible in order to maximize its penetrating power, so making it detonate early will add substantially to the effectiveness of the armor. Since the biggest threat to Allied tanks--by far--was Panzerfausts and Panzerschrecks, this was actually pretty sensible.

    15:47 Actually the weight of that frontal armor increases just as much as the effective thickness, assuming that the height of the vehicle does not change. The same plate angled back will be shorter and must be lengthened by the same amount (about 40%) to retain the same total height. The only advantages of sloped armor are decreasing the area of (dedicated, thin) roof armor, and increasing the chance of ricochet (and in modern times, the effectiveness of reactive armor [technically sloped ERA can be mounted to flat armor in a series of triangles]). Sloped armor can help the rigidity of the hull if plates intersect near the load points (idler bearing, torsion bars, sprocket bearing, tow hooks) similar to a truss bridge.

    Bar armor (SLAT, Statistical) is literally designed to just crush the fusing mechanism on RPG-7's. It doesn't work on ATGM's or other fuzed warheads. The stand off distance is actually advantageous for the missile, but the armor needs to be far enough away to avoid contact with the vehicle before it is crushed.
    The spacing is designed to have a maximum amount of empty space, as a hit on any of the bars will trigger the warhead, which will arguably be more effective.
    Essentially, you're trading a 100% penetration on basic armor, for a 60-70% failure/partial detonation of RPG's specifically.

    The most interesting thing is that the "cope cages" turned out to be effective, but not so much against "javelins" (too little data to judge not only the effectiveness of the cell, but also the effectiveness of the javelins themselves), but against suicide drones and ordinary drones with grenades. After all, dropped from a height of ten of meters, a cumulative grenade is quite capable of penetrating the upper armor of a tank, even without additional embellishment. There were already shots on the Internet of how simple nets, cages and others species saved combat vehicles from destruction.

    I'm taking videos of you featuring him with a pinch of salt because there are several mistakes to be found. Here for example "modern tank rounds travel at 3000m/s". (19:07 onward)
    No, they do not?! No tank round is that fast yet.
    I suggest
    1. To check facts because this one was an easily avoidable mistake and
    2. Also double check yourself if you are really into this topic

    I think you should add in today's combat, armor protection also gets supplemented with active defence systems / active protection systems, not just the older smoke discharging mortars. I guess that will be way of combat moving forward is adding more countermeasures to neutralise threats.

    T34 was not the first or the only inter war tank with slop armour.The soviets just use it more,sacrificing space and crew ergonomy.There is a reason why no one used the t34 idea after it,not even the soviets.

    Sherman armor is relatively thick at nearly the same protection value as the Tiger 1 upper front plate. The issue is that the guns the Sherman faced were made to penetrate much thicker armor values.

      the Sherman was a overall much better tank than the Tiger I. Let´s not forget that the sherman was produced in much much higher numbers and tanks are made to support infantry to breakthrough. The sherman was cheaper, more reliable and didn´t need to kill tigers as this was the job of tankhunters, planes and artillery.

    Normally I wouldn't dare this, but can I venture two points regarding the T-34's sloped armour?
    1) Sloped armour doesn't directly save weight. For a given effective thickness over a given frontage, the volume (and thus weight) of steel required is constant - it's the effective thickness multiplied by the frontage of the plate. Sloping a plate costs internal volume but lets you use a plate that is longer but thinner and thus easier to manufacture - something that really matters when you need to churn a design out by the tens of thousands.
    2) T-34 was not the first tank to use sloped armour...not by a long shot, although it is probably the first to take it to such an extreme. The BT series, the Vickers 6-ton, even the venerable Renault FT all have sloped frontal armour. Even the Pz.IV which is normally thought of as a box has a 10 degree slope on the front glacis.

    My ocd could not stand these few misconceptions that i feel are getting in a way of otherwise good and informative video, so
    few things that im going to bother to point out
    Cast armor in ww2 was inferrior in terms of protection versus rha or rolled homogenous armour. You could create more natural and more varried shapes that by themselves may provide better protection but if you take 100mm thick cast plate and 100mm thick rha plate, rha plate would most likely stop a projectile that would otherwise penetrate cast armor plate( ignoring all possible variables due to resource shortages, workforce experience and so on).
    Sloped armor was and is heavier to cover the same frontal projection size versus simple flat piece of armor. Unless you are planning to armor the top part of hull as much as the front itself, which was never the case, vertical plate would have smaller area and top part of the hull would be much thinner, therefore lighter overall. It was about having more chance to ricochet incoming shells without your armor plate having to soak up the whole kinetic energy by itself. It was never about weight saving.
    And finally, heat rounds do not penetrate by molten metal jets, its the pressure that does the penetration and under that immense pressure, many metals become superplastic. They may not even reach their melting temperature but still act like they are in liquid/solid state. Really complicated physics, but not necessarilly molten and even if it was, it would not be the temperature eating at the armor plate in front of it.

    Oh here we go again. 1) armor mobility, firepower. was initially based on cruisers by Jackie fisher. not tanks - and while a desirable outcome is not an initial priority in a tank's design. things like cost, capability, and volumetrics all come beforehand. 2) not much evidence on sandbags - you have a whole archive full of information and tests on this subject, all proving it did. try to avoid reading wiki for your references? 3) Sherman had poor armour? - its just as thick as its german contemporaries. 4) sloped armour has been around since ww1. 5) sloped armour does increase the weight of the vehicle as the plate has to be larger to cover the same area. - this is basic geometry. 5) 'Chobham' begins back in the late 50s as ideas. first fitted to FV4211- then the XM1 and Abrams - then challenger. - the armour type is generically referred to as Chobham, and the individual setups/compositions have names such as Burlington, Buckhorse, Dorchester and so on. it was primarily designed to stop shaped charge attacks not APFSDS at the outset. 6) shaped charges are not 'white hot' the temperature is lower than the melting point of the material. often between 400-700 degrees and are not 'molten' in the normal sense of the word. 7) you can make chobham styles in curves, but it's not very effective so why would you. 8) cage armour does not TRAP rounds, its designed to disrupt or break up the cone before the fuse can contact the main armour. 9) ERA does not neutralise the impact, it's there to disrupt the jet or projectile, to prevent it from striking effectively. - awful video full of mistakes and tropes.
