No, no you’re quite wrong with the caption in the thumbnail. It’s probably best that you don’t try to surmise what other people do and do not have in their heads. As we’ll see below, you statistically haven’t got the capacity to imagine what other people may or may not know. Spaced armour* is for defeating projectiles. It ruins the necessary standoff distance of shaped-charge ammunition and causes ball ammunition to run untrue, thereby limiting its stopping power via a tumble or a deflection. Say, do try to remember that you are a KZbinr. Statistically you’ve got fewer brain cells than the average cabbage. Though, you may be of the tiny percentage (it’s something very low, less than 3%) that isn’t cabbagesque, though from what I’ve heard in the past, I’m sticking with the stats. *How it’s spelt when using the English Language albeit a French word fog up. Unless you think you’re French of course… Most Americans pretend to be anything other than American, though I don’t suppose anyone should blame them for that. If I woke up from this dream to find myself an American citizen, in America. I’d be very thankful of the ease in which one can secure oneself a firearm over there.

[@TheArklyte]

Slat armor isn't misunderstood and was around since 60's at least. Russians are being ridiculed for cope cages because they weld them improperly resulting in uneven gaps and use L and C metal profiles instead of "blade" strips, which causes an INCREASE in likelihood of projectile fuzing. Gaps need to be specifically just a few millimetres thinner then caliber of most common projectile you expect to be attacked with(usually 73-82mm), they need to be parallel and the "blades" need to be as thin(from attacker's perspective) and rigid as possible. Tl;dr NII Stali has a literal textbook on how to make slat armor and russian army failed every part of it 😅

[@brokeandtired]

Worth noting that Western Slat armour is designed to crumple and shatter a warhead of a heat round. The gaps are to let the fuse through unimpacted and the bar slats break up a shell and make forming a jet near impossible.

[@russellprice8971]

Nicely covered. Spaced armor has been introduced many times over the years, and in each case was meant to counter a specific battlefield problem. For example, the spaced armor on the front of turret and hull of the Pz IIIG and H employed a hardened plate, and was intended to help defeat certain types of kinetic rounds in use at the time. Yes, it is a complex subject. No one engineering solution, sadly, will provide a complete defense against all possible threats. "Ya pays yer money, and ya takes yer chance"

[@hideshisface1886]

Before I watch - originally intended against AT rifles. Note that the first German tanks these things appeared on were Panzer III and IV - they had something around 30mm of side armour - which could be penetrated by Soviet AT-rifles, such as PTRD-41 at relatively long distances even. Hilariously - Soviets initially believed these side skirts were made to make the identification of the vehicles more difficult - disguising older tanks as Tigers.

[@Grubnar]

The Soviets had a point. After the Normandy landings, many PanzerIV tanks were mistakenly reported as Tigers, because with the side-skirts and extra turret armour, when spotted from a distance, they looked like a Tiger tank.

Somewhere i read that the "Schürzen" also made it difficult to place mines or charges on the tracks of the tank in close combat situations. There is a movie from the Wehrmacht about a "Panzervernichtungstrupp" where you can see how they place a mine on the tracks of a t 34 who was not equiped with any "Schürzen". So it was easier to place them and therefore easy to get out of the situation.

[@randolphstead2988]

[@JGCR59]

Thing is the Red Army issued these AT rifles in huge numbers. Like on Platoon level. So every time a german tank attacked, it was pretty much sure to be fire at by these rifles. Even if the rounds didn't penetrate (the theoretical max penetration that might penetrate a Panther's side armor required point blank range) they could do damage to tracks and exposed equipment and if nothing else, un nerve the crew by constant hits. So protection against 14,5mm AT rifles as essential even if they rarely killed any of the german medium tanks outright, even in 1941.

Drachinifel has an excellent video about spaced armor specifically in regard to the Littorio class of Italian battleships.

[@Darilon12]

Great video. This topic is often discussed anecdotally but you delivered the facts. I've one small nitpick though. Or maybe I'm missunderstanding your explanation. 1:14 "When a bullet struck these plates not only would it begin to slow down, but it would alter the trajectory of the projectile causing it to hit at an angle ." More importantly the round is destabilized and it will not hit the main armor with its full mass behind the point of contact - resulting in loosing much of its effective kinetic energy and by that its penetration potential. It's less about the change in trajetrajectory and more about the change in orientation relative to the trajectory.

[@DIREWOLFx75]

Similar style of sideplates also exists under the name of breaker plate, where a relatively thin but extremely well-hardened piece was used as spaced armor, because it was not technically possible at the time to make THICK such well-hardened plates(or rather, at least not in massproduction), they couldn't be used as part of the overall armor, but placed as spaced plates, using only the thinner plates, they were meant to deform KE penetrators, or "defang" the EFPs of HEAT warheads(because the extreme hardness of the plate means that the EFP takes slightly more energy to penetrate, which means that when it hits the main armor, it is more blunted and slightly slower, meaning that the armor has greater chance of stopping it). "schurzen" Came about at least in part specifically due to the rapid deployment of the PTRD and PTRS 14.5mm rifles that USSR put over 400 thousand in service during WWII. As these were of such high penetration and caliber that they were capable of serious damage against anything without enough armor. Going through 30mm was common, 20mm was effectively guaranteed, and 40mm was not unheard of, even more happened.

[@someone75413]

EFP /= HEAT. EFPs can be disrupted by high-hardness plates much like any other KE penetrator, but HEAT jets are not meaningfully impeded.

[@gavinphillips3973]

Fascinating video, really enjoyed that one. Since the Soviets looked at a prototype "T-44-100" which featured 6mm thick skirts for anti-HEAT purposes and yet the following T-54/55/62 lacked these entirely, they most likely came to a similar if not the same conclusion? Keep up the great work with the videos. 👍👍

@@ConeOfArc there’s also another reason. The wheels on the soviet tanks like T-44, T-54/55, T-62 are pretty large, working somewhat like the side skirts. Once switched to the smaller wheels on T-64, the side skirts started re-appearing.

Good presentation, wire mesh, Chain-link fencing and steel plates are useful with correct placement vs RPG family of warheads due there having a nose initiator. US forces in Nam used Chain-link and steel Pickets up 6 feet long to space the fencing up to 2 meters in front of the vehicle to be protected. Some modern systems like TOW use 2 layers of metal as impact sensor with power from the internal battery in the round for power negating most chances for fuzing failure along with inertial backup in the detonator assembly itself.

Glass at certain thicknesses is more effective than the same thickness of steel.

[@jeffkardosjr.3825]

[@RandallWeeks]

We found out in Iraq that armored glass is pretty impressive against lots of anti-armor weapons. Stuff that would go through armored doors on trucks like butter usually didn't defeat the windows.

[@prjndigo]

To give ad. explanation of heat solidus jets penetrating through some spaced armor better, if the spacing is wrong for the charge's dynamics it can end up simply turning into a funnel that keeps the jet concentrated or even attenuated into a better jet. Atmospheric temp, contact surface, initial plate incidence angle and all have effects on the efficacy of the solidus jet. If too much energy is taken away or added the jet will transition out of being solidus to either a foam alloy if cooled or a plasma if heated further. There are even extreme circumstances where explosive reactive armor increases the power of a HEAT shaped charge and this whole set of effects also has a huge impact on missile speeds, timing and size of a secondary charge on dual or triple warhead systems.

[@sthrich635]

Why didn't the Germans put side skirts on 251 halftracks too? Given they usually accompany with Panzer IVs and faced AT rifles fire too.

[@kirotheavenger60]

I've not read any official sources on that, but my initial thoughts would hinge on a few contributing factors, Perhaps the base armour of the halftracks was just too thin. Perhaps the ATR would penetrate the base armour after the shurtzen anyway. Weight, the halftracks were lighter vehicles and the added shurtzen weight may be too much. Especially as their thinner base armour may require larger or thicker shurtzen And perhaps the shurtzen would get in the way of disembarking infantry. I'm not sure if the Germans always used the rear hatch or if they sometimes jumped over the side (it seems rather high though, I'd probably weigh this least)

About time, the effective jet range of modern HEATFS/ATGMS are about 9-50+ meters. Spaced armor from it's first introduction has been used for projectile decapping/asymmetrical shearing. Thin plates might as-well not exist if you use relative energy, 9M128M goes about 18km/s with a jet that has a peak energy of 82MJ. The cages on Russian tanks were installed due to an order from Gerasimov because he thought it would defeat FGM-148, it was not optional for the crews. Thank you for this video.

[@pauleveritt3388]

The earliest example of spaced armor that I am aware of goes back to the middle 1600s when firearms became more common on the battlefield. Blacksmiths would make breastplates, three layers thick with space in between. A properly made breastplate could spot a musket round. This idea has been around a long time. This type of protection is built into the International Space Station to deal with micrometeor hits.

[@marcdavis4509]

If I may add in WWII every side was developing fusing and firing of HEAT warheads differently. In spin stabilized HEAT rounds up to 3/4 of the effect would be mitigated by the spin of the round from rifled barrels. Such as from tank or recoilless rifles. So the spaced armor would actually help dissipate the rest of the energy of the round. So I feel the weight tradeoff was more beneficial in addition even if the extra protection could be minimal there was an effect that the crew would feel more confident in their survivability.

So what we have learnt that generally spaced armour is to give a higher rating (0.762/1.27cm or 1.27/3cm) as it removes the ballistic cap and removes fragmenting from modern ERA and is a precursor to NERA where composite armour can reflect kinetic energy into the rounds themselves before it engages the main armour

It’s interesting that later Pz. III models despite having the thickest side armor of all the German mediums still had the skirts when they were immune to the initial AT rifle threat.

[@wolf310ii]

The Pz III didnt had the thickes side armor, it had max 30mm, the Pz IV Ausf E had 40mm (2x20mm), and the russian AT rifles could penetrate up to 40mm, so the Pz III wasnt immune

[@johnnycab8986]

I believe the concept wasn't only due to PTRS AT rifles, but was also conceptualized to help mitigate mobility kills from artillery, and also shaped charges. Germany had a different style of Schurzen for the Western front, which was a mesh style, with holes greater than 14.5mm indicating it wouldn't be very reliable against AT rifle fire. Note that this style occurred in the West where AT Rifles were not used much, but HEAT projectiles were. There are also quite a few pictures of Soviet vehicles with both mesh style spaced armor and solid armor plates. In 1943 the Soviets produced 68 T-34E models which had spaced armor on the turret and hull sides. Germany did not use AT rifles that much after late 1942.

[@LoserDestiny]

The Germans absolutely considered the Shürzen as a measure against HEAT rounds. Even the mesh-Schürzen (or especially them, since their impact on AT rifle rounds is even more doubtable) were considered as such. They even tested various types of Schürzen material against one another in late 1944 or early 45, concluding the mesh screens didn't provide sufficient protection. I remember reading that in the German Waffen-Revue magazine, can't tell in which issue though.

[@ConeOfArc]

It's likely they tested it however I was unable to find anything aside from information saying they did not consider it as protection for that

WT taught me that, no HEAT won't be stopped cus the jet of the heat is still powerful enough, even if detonating with some air gaps.

[@henryruch4101]

I live near that museum.

[@PitFriend1]

The effectiveness of spaced armor depends not only on the thickness of the extra armor but also the space between the armor and the main tank armor. The effective jet from a HEAT warhead is a fixed distance. The jet treats the empty space the same as actual armor. So for example f the HEAT warhead will penetrate 100mm/10cm of armor like the original bazooka had the penetrating jet only would go that far and still be effective. So a plate thick enough to detonate the warhead 10cm away from the tank’s main armor has the same effect of adding 10cm of armor to the tank and would totally prevent the warhead from damaging it. This stopped being as effective when warheads started getting more and more powerful so the spaced armor would need to be further and farther away from the tank.

Yes and no. The air between the spaced armor and the main armor does reduce the penetration slightly, but the jet is not a fixed length. You can see proof of this in the video clip of the BMP being shot as the jet goes MUCH further than the ~400mm of penetration that weapon can achieve. To effectively stop a HEAT round you either need an astronomical amount of spacing before the main armor plate or something denser than air. That is why composites work well at stopping HEAT because they are able to reduce the energy before it achieves penetration.

@@ConeOfArc Indeed.If memory serves correctly US Ordnance depot did a study on this in 1944 fixing a sherman with specially made plastic or plastic-cement compound.. The results was that the amount of physical layering required made it beefier than a jumbo, very little overal improvement in protection,and massive amount of added weight, along with the added issues.

Very good video I was not very good with physics but it is definitely used here

[@jerrymail]

Thanks! Depending on the source, one time you are told that it is protection against anti-tank rifles, another time, that it is protection against shaped charges. It is quite confusing! Now I know the real reason!

[@ConeOfArc]

As shown in the video there was some confusion around their purpose when the Germans introduced them. This is likely where part of the misconception originated from

[@peterking8586]

Even on Chieftain & Challenger the skirting plates are considered a defense against HEAT.

[@Order_66clones]

Did any other countries try to copy the type of side armor ? And if so do you know how much Pen. the panzerfaust would’ve had on the m4s side armour?

[@jonahkolell]

Awesome video!

[@Del_S]

They were extra parts to be optional in future model kits, of course.

'Not for what you think" *Is exactly what I think.*

[@Dodgerambo100]

The "schürzen" were installed to reduce the spalding of the Main armour if it is hittet by APHE or HE rounds. The reason why later models uses only mashes. The Main reason was to initiate the Explosion of any projectile befor it hits the Tank.

[@ConeOfArc]

No it wasn't, the documents relating to it specifically state it was for protection against AT rifles. Anything else it protected against was a bonus but not the intention

[@dariostabletopminatures]

Thank you for this One!

[@SitioLumbia]

Schürzen today is Kontak-1. You put it on everything.

A new upload from MrSteveGamer!

Do a video on the locust tank. Tge heritage armor museum should have tte locust we house at the now defunct military museum of southern new england. It would be nice to see that lil guy again plus tgere super rare. I used to volunteer at the military museum of southern new england. I was there the day we had artifacts from 9/11 that made local Danbury news and helped set up the exhibits.

[@ConeOfArc]

They do have a Locust so whenever I cover that I will likely film there

[@corsola9907]

Schürzen makes tank look cooler

[@call-sign-idiot2950]

Cone of arc was at the American heritage museum!?

The Soviet anti-tank rifle operators were instructed to aim at the vison ports on the sides of the hull and turret of the Panzer 3 and 4's to wound or kill the driver, radio operator/bow gunner, gunner and loader. The spaced armor plates eliminated that threat and the Germans ability to see out from either side of their tank. The US tankers hated the German shaped charge rockets so had frames installed to hold two layers of sand bags to reduce or deflect the energy of their jets when it hit at a sharp angle. One company of M4's used sand bags filled with quartz pebbles which proved to be ideal for reducing the energy of the shaped charge jets since it had to go around the pebbles before reaching the cast and rolled armor. The US Army got ordnance to develop quartz pebble armor protection. They came up with long sheet metal boxes filled with quartz pebbles held in place with a mixture of wood fibers and asphalt. The boxes were hung from the turret and hull with each one held by a catch that could be released from inside the turret or hull. Those worked very well yet never entered production since the US Army felt that the war against Germany would end before any would arrive to the front lines to use.

Excellent Presentation 👍👍👍

[@Hornet_Legion]

since tigers and ferdinands didnt have schurzen i think it would be safe to say it was designed to weaken anti-tank rifle projectiles that if they hit unskirted side armor even if they didnt fully penetrate they might unleash spall or plugs of steel flying through the inside of the tank.

[@Kuschel_K]

Sideskirts did certainly not make the Panther II obsolete. The Panthers lower side armor is 40mm, which is already scraping the potential for a 14.5mm to go through. Just making the plate 5mm thicker would have made it nearly impossible to get penetrated by Soviet AT rifles. The side skirts on the Panther and Tiger II most likely protect against HE rounds that would penetrate the the sponons floor armor, if they hit above the tracks. As well as protecting from direct hits against the tracklinks by HE rounds. The Panther was still very vulnerable from the sides to T-34s and Shermans and even Soviet 45mm AT guns, thus the increased side armor of the Panther II would simply increased the survivability against such threats.

[@ConeOfArc]

I meant to say something along the lines of "unnecessary" as I corrected in the subtitles. Didn't have another good take for that line though

[@unfortunatereplica8442]

I remember watching a vid on the ptrs-41, and hearing that Germans installed the skirts to stop the rifle
