Isn't this just how a shaped charge works?

[@operationalfacts5602]

@@jbradley8659 Yes, Explosively Formed Penetrators is a type of shaped charge.

[@SofaKingShit]

I'm glad you said it was a simulation. It did seem like the slug was actually going across the screen somewhat slower than 2km/s. Anyway a mere slug going through armour is pretty impressive, l would have expected that you would need s snail with a really thick shell, one of the pointy ones you can see on a beach.

I remember the story of how matches were invented by accident by a pharmacist trying to develop a new explosive. Would be nice to have 1. enough time in the job to do this and 2. being allowed to do do so today in the job. Would make it more exciting

[@doggonemess1]

Back in the eighties, a wealthy businessman was killed in his armored limo by an EFP that was in the basket of a bicycle beside the road. It was set to go off when it sensed the second car pass, to allow for the security vehicle leading the limo. It went off perfectly and hit the limo so hard that it spun it 180 degrees (due to the armor absorbing some of the projectile). The victim was killed. I can't remember what the specifics were, but I remember being a kid and thinking how incredible and terrifying this was.

[@kaungsan6272]

The movie?

[@RW-rt5nd]

Think it was the German Red Army Faction (or Baader-Meinhof gang) that carried out that attack if I recall correctly. They even told the German billionaire the day they intended to kill him and used a laser activated bomb to initiate the attack.

That’d be Alfred Herrhausen. They never truly found out who did it, but my money would be on the Red Army Faction.

I mean it meant to be anti armored vehicles so ye ofc it gonna need lot of energy

Its designed to destroy mbts (well it does destroy mbts with no issue)

Me ✋

[@krizzledarealist]

Yup!

[@LundGhost]

loooolll

[@erikrichardgregory]

So EFPs do not form a “jet” (like a conical shaped charge often used as a HEAT round against tanks)? It forms an actual, solid projectile hurled out like a bullet at great speed?

[@operationalfacts5602]

Yes, they don't form a jet but deforms the metal into various projectile shapes. In both cases, HEAT and EPS, the liner always remains solid.

[@erikrichardgregory]

@@operationalfacts5602 thx for the KT (Knowledge Transfer). I did not know EFPs did that. I imagine it's a completely different animal for armor engineers to defend against

Imagine this thing has proximity fuse, it could take down attack helicopters with thick armor.

So conical shaped charges are like the splash back from dropping something in a pool of water, whereas EFPs are like weaponized popping cap things from the 80s.

[@Tomartyr]

@@Keklord_ It didn't. You need High Explosive, which isn't in shotgun shells, for this to work. They just made an improvised shotgun or pipe bomb.

[@kennethng8346]

What is the difference between an efp and an anti tank heat round?

[@operationalfacts5602]

HEAT is a type of EFP

[@maxjoechl5663]

HEAT rounds have conical liners and create a jet of metal (note: contrary to common belief, the metal isn't "molten" - it just flows like that under the immense pressure). The jet achieves optimum penetration if the round detonates ~1 or 2 feet away from the armor, but degrades dramatically at distances >2m. EFP‘s with concave liners (like in the video) create a slug with a generally lower penetration, but they will retain that penetration over much greater distances (like ~20m). As a result •HEAT is used for warheads that are launched directly at the target. •EFP’s are used in off-route mines (where size isn't the issue) or in special top-attack munitions, like ATGMs with "Overfly Top-Attack" modes (NLAW, TOW-2B) or sensor-fuzed artillery rounds (SMArt, BONUS). *note:* (yes, both metal jets and slugs are technically EFP's, but usually people will use 'EFP' specifically for the slug version)

[@mrd7067]

Why isn`t this concept used in pistols, smgs, rifles or machineguns? My guess is that since it`s so fast it`s also quite accurate up to a certain distance without the need of rifeling in a barrell.

[@operationalfacts5602]

The container is destroyed in the process. So my guess is making the barrel of the gun thick enough to not be destroyed would required turning the gun literally into a hand held cannon.

[@apolloaero]

@@operationalfacts5602 what if it launched a projectile a set distance that would arm after a certain amount of rotations, that way the explosion happens at a safe distance. It'd mean there's a minimum range tho, but safer that way

[@Qaptyl]

cmon normal guns are good enough if we upgrade them, itd be railguns not a fricking hand EFP

[@midgetman4206]

@@apolloaero The accuracy would probably be terrible. It'd be better to make it a shaped charge. That's if it doesn't destroy itself from the acceleration.

[@maximus9812]

@@apolloaero This is pretty much how most anti-tank weapons work. The penetration is proportional to the diameter of the warhead, which is why you don’t see this scaled down to bullets and such.
