McCurdy's Armor™ vs. RPG

Slow motion video of test in which McCurdy's Armor™ defeats a rocket propelled grenade (RPG).

[@Nosht]

The slat armor did its job. The electrodes from the fuze where cut resulting in that the shaped charge flattened itself against the armor before detonating. If the warhead had worked properly, we'd see a metal jet shooting through the thin metal armor.

[@alloy299]

It lets the fuse (the pointy thing that activates the warhead) pass but damages the warhead that is wider, that way when the fuse finally hits the armor and activates the warhead, it is either not functional or has been deformed/broken, making it less effective.

[@alloy299]

Normally, yes.

[@DanFrederiksen]

Wiki says it only works about half the time. And I would have less faith in it than that in practice.

[@_armoredglasscannon2520]

interesting

[@hazardous458]

Dan Frederiksen Well, slat armor can destroy a projectile no matter the angle, a perfect hit like that would stop it, a non perfect hit can also destroy it, just a hit to the main body but the fuse staying intact will negate a jet from forming. If the contact fuse hits the bar, it can cause a imperfect jet that won’t be able to penetrate armor.

[@testfortester7131]

0:12 it worked

[@ID-8491]

Just to clarify a popular misconception. RPG (meaning the Russian designed anti-tank weapon) does not stand for "rocket propelled grenade". RPG stands for Ruchnoy Protivotankoviy Granatomyot which means handheld anti-tank grenade launcher.

[@privateassman8839]

Yes. But RPG still stands for "rocket propelled grenade" when used to describe the broader category of shoulder-mounted shaped charge projectile launchers.

[@wotanscry1594]

it not true - dont believe his lies! RPG stands for Russkia Peoples Golupe

[@jimmylaze]

It means role playing game actually

actually is a recoiless gun , there are no rockets used to launch this devices is an explosion inside a tube that shoot the explosive head , thats why they have a shit ton of backblast

[@cartersharpnack]

[@357Maxim]

Slat armors are effective against RPG, but not against more modern rocket/missile. Also, slat armors have a 45-55% efficacy: If the piezo hits the slat, the shape charge will trigger and punch through 300-400mm RHA. Good vehicle design, base armor, Add-on armor, spall liners, FSS (...) shall be part of part of the protection package.

[@marleyboy7732]

[@AlBundy310]

and what about the twin warhead rpgs?

[@hazardous458]

Than you’re fucked

[@_armoredglasscannon2520]

It wont sadly. RPGs or anti-tank weaponries with twin warheads or tandem shaped charges are designed to defeat the slat armor, era, modular armor, and thickest frontal armor of any modern mbts like abrams and T-90.

[@hazardous458]

_ArmoredGlassCannon [IRD] [NA] No, the point of tandem is to have the primary charge destroy era blocks and slat armor. Mbt uses composite armor. The first charge won’t have anything to counter so it would not have any effect other than weaken it a bit as the first charge is very weak.

[@hazardous458]

Doom Guy yes it will help but it won’t counter composite as the other person said.

[@22phan]

Slate mesh armor, no big deal

[@77Avadon77]

Shouldn't the slats be tighter together?

[@hazardous458]

No, the slats are spaced apart so the fuze wouldnt hit the bar, if it hit the bar, the fuze would engage thus detonating the charge and allowing a jet to form and penetrate vehicle

[@miguellopez3392]

the armor is meant to damage the warhead of the anti tank munition without detonating it, the damage from the shaped penetrator making it much less effective, there is still a chance the munition can detonate before its damaged.

[@KonuralpBalcik]

[@TEddisonTheEpic]

No they would be fine

[@jeffbanks9955]

so it doesnt work then?

[@cartersharpnack]

It deformed the charge and it actually detonated a bit earlier than it would have, causing a lot less damage and penetration.

[@HHSTT]

What's the point? It still hits the armor plate.

[@ariq4209]

(Yes I’m late) The mesh deformed the shaped charge so it doesn’t form the metal jet which would cause penetration. Instead it explodes like a normal frag grenade which is harmless to tanks.

[@HHSTT]

@@ariq4209 Oh, I see. Cool. Thanks, bro. Keep up the good work. 👍

[@JohnHughesChampigny]

Now try it with a modern tandem warhead as used by, for example, Hamas.

[@odisy64]

why? most of what they have are single charge warheads.

[@arielvaldman]

Can you clarify by which means would a tandem charge do better against this setup?

[@odisy64]

@arielvaldman has a higher chance of properly setting off the shaped charge but their is still a possibility of both warheads being damaged before contacting the main armor.

[@arielvaldman]

@@odisy64 vague answer for a clear question,if the precursor charge is damaged,then the main charge wont detonate,so again,how would a tandem warhead do better against cage armour?

[@odisy64]

@arielvaldman because the first charge can still go off although its been damaged and not making a proper penetrating jet, the main charge can go off because the first one did detonate, just not properly.

[@rjlee3112]

Now how about they actually use a live grenade?

[@kuhaku9587]

+RJ Lee Because if it work against a live rpg it hurt your feeling ? There is a video in Afghanistan where a MRAP get hit by a RPG with that and it work perfectly fine, again.

[@rjlee3112]

Nop. The thing is that people seem to misunderstand what the armor is supposed to do. It works if it manages to deform the shaped charge or prevents optimal jet formation. That does not happen reliably though. And there are tests of this armor that show that even a deformed RPG can still penetrate the armor behind it. Most unconfined vehicles with high internal volume will be fine even without this sort of additional protection. Its used because its cheap and it does have a chance of reducing damage to the vehicle itself. Its not, never was and will never be an actual safeguard from anti-armor weapons.

[@kaim268]

+RJ Lee well wouldnt you rather have a, lets say, 40% chance of stopping a shaped charge than having no prevention resulting in 100% penetration every time?

[@daltonagre]

Armour worked. I live in Brazil.

[@HeirofGojira91]

BUT what if it was MULTIPLE RPG blows? how many rounds would it be able to digest? ALSO what if the following weapons were used on the armor (assume 1 shot each) 1.) A 75mm Sherman gun firing the M72 AP round 2.) A 75mm Kwk L/48 firing Pzgrt 40 or 3.) A 76mm M1 Gun firing HVAPS or the 90mm M3 AP rounds? 4.) A 76mm PaK 42 of the Panther firing APCBC-HE 5.) A Sherman Mayfly 1c firing the QF 17 pdr using APCBC-HE 6.) A Tiger I 88mm firing Pzgrt 39 7.) A PaK 43 firing Pzgrt 39 8.) BS-3 100mm AP rounds 9.) 122mm BR-471 OR if it was subject to: 1.) HE barrages from the Sherman 75mm or 90mm HE rounds? 2.) HE barrages from the 88mm of a Tiger I 3.) HE barrages from the PaK 43 4.) HE rounds from the BS-3 5.) HE rounds from a 122mm gun cannon 6.) HE rounds from the 152mm guns

[@russianmilktruckmafia1813]

That's an interesting question, all the rounds you first mentioned are AP, either solid shot or with filler which would penetrate the armor without trouble, but the thing is that the RPG fires a chemical round, that is a HEAT warhead that depends on an explosion inside the warhead to shoot molten metal onto the armor to achieve a penetration, a HEAT no matter the speed or distance (the RPG's rockets actually travel slower than a 9mm bullet) will always achieve the same results unless it is detonated early or the warhead gets damaged before impact (as seen on the video). AP/Solid shots and penetrating rods rely on kinetic energy to achieve a penetration and can only be defeated by armor plating, that is Rolled Homogeneous Armor (solid steel alloy) or Composite Armor. Then onto the HE barrages, these do not penetrate but detonate on impact, if they are strong enough they can deform the metal or cause a concussion that will cause internal damage on the vehicle. A Sherman 75mm HE wouldn't be too lethal whereas a 152mm HE round can cause nasty damage by concussion.

[@HeirofGojira91]

Hmm what about REPEATED BLOWS FROM HE 75mm Sherman shells? So direct repeated barrages? Or at the very least internal damage and crew casualties would be inevitable? Or the armor will eventually give in? Given I thought hmm - if the SLAT armor could endure well a fair amount of firepower ...
