@@Fireatank yes, well enough to get an idea. But he shouldn't have said that the copper doesn't become a liquid, because it certainly does. It's my only issue with the video and he actually did a great job with the AP rounds in finding those obscure ones that were basically rendered useless before they were even fielded.

He sounds like Mike Boyd

It seems like 80% youtubers have thick scottish accents

And also germany stoped to produce it in large numbers because tungsten was needed for other components. Even if tanks had some of them, they were only allowed to shoot it if there was no other option

You know that there are many types of shrapnel shells?

@@o-hogameplay185 tungsten nees to Be buy to spain at this time they were reluctant to do And they needed so much for turbines for jet aircraft engines as the Jumo 2 on ME 262

@@o-hogameplay185 Tungsten projectiles were not really a thing for Germany in WW2. Before being allowed to shoot a round, you first need it in your inventory ;) A former French Navy EOD friend only had one 20mm AP round to show in his otherwise huge collection after his career so that says something.

warthunder is not realistic.you dont need tnt to destroy a tank

HEP stands for high explosive plastic, basically a german variant of hesh where it used plastic, not entirely sure about it tho.

@@Thurden_mixd every Shell is good if yk how to use it, except shrapnel, shrapnel rounds suck

The issue is that in War Thunder, APHE rounds detonate in a spherical pattern, able to travel BACKWARDS from the point of detonation - IRL, momentum still carries the explosive FORWARD in more of a cone shape, only slightly wider than that of a solid shot

@@ArmorCast Ah, that makes sense. Yeah, I imagine that would make it considerably less effective in War Thunder. I kinda wish that was modeled correctly now though, would cut back on the dominance of APHE in most of Rank I-IV. Not like War Thunder has any shortage of physics problems to work out.

In the videos of an air to air missile exploding you can see it blow and then turn into a ring then a funnel. That shows you the effected area of an explosive round, roughly speaking.

@@ODST_Parker Its not that bad when you take into account how large the game is

@@reahs4815 i know right

Would love to see it happen

Can you explain what you mean by specific distance? i thought HEAT round does not rely on firing distance like other kinetic based rounds?

@@farrela3620 as in stand of, not range to target. There are a few shapes these ammo types use that are effective. In the front there's a sensor that when crushed detonates the explosives at the optimal distance to cause the most penetration on the target. Most have an active sensor when they are produced and some activate when fired from the gun or launchers. Stand of would've been a better term to use but many have a better understanding of the terminology of distance. When talking about range, distance, length and other words used to denote a physical measurement some clarification is sometimes needed. Probably should've added them into my explanation.

@@farrela3620 and many KE rounds that are penetrating rods lose very little in way of energy or velocity over the course of their flight path, even out to 3,600m. They will lose some, but they are still very effective at longer ranges. KE rounds are also considered overpressure and will have more powder behind them for maximum velocity. These can reach 1,800m/s. Where as your typical HEAT leaves the gun at around 1,300-1,500m/s. The difference is seen in trajectory. If not for the atmosphere or any other forces besides gravity, a miss could send one of these rounds into low earth orbit. One reason the M829A4 cant go any faster than it does currently is because it's a segmented rod, having 2 pieces to defeat different protection systems or armor layouts. That also creates a problem when you go a little faster, the rod fails and comes apart. This isnt an every time, but it was enough to set the charge to the maximum. Also the only accurate simulations of what a DU APFSDS does on target have been when I was in the military and they had to use special commands to make it happen in the sim because the strange physics were unknown and many people have no idea that the DU actually burns it's way through armor. The only things that will save you is DU and Tungsten, or very thick and heavy steel armor. And if you actually manage to survive a penetration event by a DU rod, you will die from DU poisoning because you likely didnt hold your breath while getting out and away and while stripping down and taking a shower. Scary stuff to think about.

@@Deathbomb9 scary indeed

@@awashburn6944 went back and reread my comment. It appears a word was absorbed into the ether. It should say that DU burns on it's way through. Referenced to it being pyrophoric. As for shape charges we are both correct. It depends completely on the size of the cone, and the amount of chemical charge behind it. The heat that much larger shape charge devices will build up isnt transferred from the explosive. It comes from the forces and pressures of it forming into a "jet". I never said it was a plasma, I said like a plasma in trying to use common terms others could understand without having a full course of knowledge on the subject. The instantaneous temperature changes happen so fast on bigger cones (8-10in di.+) that it isnt commonly known about. The bigger ones do get very hot but it isnt what causes penetration. You are correct there. The heat produced during penetration also isnt enough to melt armor but the forces cause the deposits of copper as it punches through. The cone turned jet does heat up but that heat is also lost very quickly on smaller ones (sub 6in) the heat is just enough to cause the copper to reach a very soft taffy like consistency. There is more than plastic deformation happening. In the larger ones the copper does actually get hot enough to become a liquified jet.

Thank you my friend, always means a tonne to get comments like this!

I was wondering the same thing. Former tanker 1st Battalion 35th Armor 1st Armored Division, C Company 3rd Platoon M60A1 Erlangen Germany 1975-1978

War thunder is better

Eh No... just NO!

The fuck have you been reading/smoking?

I was just about to ask the same thing, the fins would have to be canted though to impart spin instead of removing it

TLDR: No - wouldn't work Using stabilising fins to intentionally SPIN the round rather than to STOP it spinning is a whole different kettle of fish. To STOP the spin just requires flat fins that create drag against that sideways momentum, but to actually START the spin you'd have to angle/curve the fins in such a way that they create that rotation like a fan blade, WITHOUT disrupting the course of the round and leading to inaccuracy. What you'd have to do is use a smart ammunition that will unfold the curved fins, start the spin, but then immediately fold them back in again... by that point you're just suffering from diminishing returns

Given HESH has better performance against building as well as being a deep part of UK tank doctrine it would make sense and I like the acronym FSHESH.

@@ArmorCast What if we a go a bit further and develop tank-launched 🅱️ESH ATGM? There are HE warheads for pretty much every modern ATGM and I know some of them tend to spin.

@@komradearti9935 that source actually demonstrates exactly why it wouldn’t - installing fins that INDUCE a spin rather than stopping it would produce a massive amount of both drag, and torque. The drag is okay, if not ideal, because HESH is a CE round and is already a low velocity type anyway, but the torque will make it VERY inaccurate at medium to long ranges

Liner material is heated to around 450-500 degrees C which is well below the melting point of the usual metals used in shaped charges. Pressures during jet formation and when it impacts the target are truly extreme, reaching millions of atmospheres which is well beyond the yield strength of the liner material and causes it to flow like an incompressible fluid. Apparently you can make a shaped charge liner from brittle materials like ceramic or glass, and while these might not be as effective as metals it does indicate that the mechanism of jet formation probably doesn't rely on plastic flow.

Not in NATO service - the Russians started using smoothbore guns on the T-62, around the same time APFSDS became popular, but the primary gun on NATO tanks was still the L7/M68 gun used on the Centurions, Leopard 1 series, M60 and early M1 Abrams variants, Merkava, and variations of it could be found on the Italian OF-40 or French AMX-30

.

I think a key feature of most British tanks was their fast-firing ability although I'm not sure.

The m1 abrams had a recorded reload time of less than 3 seconds during the battle of 73 easting. If your loader is fresh and has a round in his arms ready to go, loading times drastically decrease. Gaijin just doesn’t bother to model this

In theory yes. Kinetic penetration is mass*velocity (the actual shape and the materials also matter, but it is just a noversiplified version). So some higher velocity HE could have ,ore penetration, but they have a softer, and thinner frontal "cap", that cant penetrate mauch. plus the fuse will detonate upon impact. Whta you are reffering to is SAP, or SAPHE. It is basically an AHPE with thinner cap in the front than an actual APHE, and a different fuse, that detonates later than a nprmal HE, but sooner that APHE. Alos has the explosive mass between HE and APHE. Alos SAP mostly used on ships. As i know only a few tanks used it, and they were mostly prototype ones, like the SU-100Y (1-2 built and lost at stalingrad if i am correct), it's 130mm B-13 gun had HE and SAP (and other types like smoke, gas, etc)

There isn't one. Just in case they need to maintain visual contact and fire additional rounds on the primary target while avoiding direct opportunity for alternate possible targets to accurately respond.

@@eamonia The canister failed to explode or else they would not have one loaded there. You can see one canister fly out and just land on the ground

Basically think of the M103 120mm gun.

the powder charge would need to be reduced or the barrel would blow up. modern tank guns are meant for firing light weight high velocity rounds if you fire solid steel slugs the round wouldn't leave the barrel fast enough and create overpressure due to the fast burning powder needed for sabot and heat rounds.

@@Erpyrikk modern tanks don’t only shoot apfsds they carry programmable HE and HEATFS

@@accept00 yes heat fs is a lot less dense of a projectile then a solid steel slug would be.

@@Erpyrikk No, modern barrels are really strong. Really it probably wouldn't be drastically different than the 122 of the IS-2, obviously though without the benefits of rifling.

Smart rounds and tech allow it's use

Dead and tired meme

Is there a fundamental operational difference in them compared to other HEAT effect weapons? Im now curious if you are serious or trolling. I have seen the French SS.11 missiles fired and they lit up a few refit Walker Bulldogs, and while that is no real accomplishment for any ATGM I didnt notice anything particularly special about them.

Never heard of em before but thats ingenious.

@@komradearti9935 I was meaning from a technical point compared to practicality. Yes that is a great way to fit more stable HEAT projectiles......or you could slap a few SS.11 missiles on the turret as well. Practically speaking training and small engagements will make the missile a better choice but over time the shell becomes better with missile expenditure. Honestly I view this weapon system as a technically ingenious system but still consider the HEP/sabot only ammo for rifles with adding 4 pack ATGM the better solution if needed.

@@komradearti9935 the French round had the same penetration as the heat FS but was way more accurate over distance.

Never any pressure to support, my guy, you'll always be able to enjoy ALL our content freely

Spaced armor was made to defeat the HEP rounds. This is why almost every armed forces out side of the UK went smooth bore, as they become very niche rounds.

@@mike19k original spaced armour aka side skirts were made to stop anti tank rifles weirdly.

Honestly, the explanation for APC is just generally lacking here. Koala probably should have done a bit more research for that part.

Why? It is the most useless round covered. Today only really useful against concrete bunker (and who still uses those?) even our light APC's have protection against the spalling fro the HEP round.
