EFP - Explosively Formed Penetrator EFP is a type of shaped charge warhead and works on the same principle as HEAT warheads (Monroe Effect) but instead of forming a super-plastic penetrating liner, focuses instead on forming a 'bullet' which performs better against RHA and Composite armor but require significantly more stand-off distance to form the bullet for maximum penetration. Famously, Middle East Insurgents improvised a lot of EFPs to operate against Coalition vehicles in Iraq, and most recent use of these are in Gaza where they would plant the EFP in a hole on the road and would strike under Merkavas/Namer and proved quite effective.

EFPs use the Misnay-Schardin effect. This is why they are effective at range, as opposed to shaped charges (using the Munroe effect) which require a very specific standoff (not too close, not too far).

It’s GoPro footage those things can go thru a lot

We used to slide bullet proof glass between the armor and inner plate of the M115 side windows. It rendered the window usless but that was the only thing we ever saw stop ans EFP. . Big Army made us remove it because when they do get it, yes everyone survived but the glass would become airborne and everyone would get microscopic cuts in their respiratory systems. We recommend adding it to the exterior of the vehicle and where denied. MRAPs were delivered a month later.

I am SHOCKED how far away the Explosive was, i allways thought that EFPs need to be very close. but thats like a meter of distance, and its still blasting a hole through steel like its not even there.... holy crap!

Conventional shaped charges need to be close to the target as they form a thin jet of material that breaks up as it travels, while EFPs form a distinct projectile that can maintain its shape over longer distances like in the video.

Yes, another fact that may amuse you is that when the insurgents in Iraq started using EFPs, they also took to putting them above the target in trees, since people would mostly be scanning the street for something big enough to fit an amount of explosive large enough to do in an armored vehicle. But with the EFPs being smaller, and being able to go thru thicker top and side armor, they'd tie them up in the trees. Never underestimate the ingenuity of an insurgency!

@@NeeSut they are essentially the same principle. I’ve used hand made shape charges and RPGs in Afghanistan and during my testing my testing and evaluation, and with information I was given by EOD and getting to see these in action on the range and in use against enemies they have a very similar effect. You may be noting the build differences but they both have inverted cones and when detonated those cones get pushed back out and penetrate hardened steel. Neither penetrate mud walls though 😂

I wanna see them in action against tallys back in the stans.

The principle behind that explosive was used extensively by insurgents in Iraq, they would a pack a cow bell with explosives, the energy would warp the metal into a super heated blob and rip through trucks passing by upon detonation

That's amazing that it can achieve the necessary velocity without a barrel to build pressure. I wonder if there is a camera fast enough to capture the process so we could see the penetrator being formed. There probably is but it probably wouldn't survive the explosion.

@joewoodchuck3824

That's because firearm gunpowder has a low brisance meant to propel, not shatter. That's why (modern) gunpowder is called a propellent rather than an explosive. If you burn some in the open like on your driveway it will just burn. Don't do it yourself as a disclaimer. Explosives on the other hand are of high brisance and are designed to shatter things even without confinement.

Is that dark Aluminium powder

It would be interesting to see the effects on the plate if the EFP was fixed onto the plate with a magnet, or something similar. Think sticky bombs, from Bands of Brothers.

That worked pretty good.

you guys should get big pieces of plexiglass to put under and around your detonation site so you can see better and it doesn't kick up so much dirt

Nothing survives an EFP, and if you do, that was your last lucky day.

Good old Munroe effect.....

Nasty Piece of work But one heck of a punch to it!

Do you not have high speed cameras?

Daaaayyyyyuuuuummmm😮

Cool

Would love if you gave US measurements as well as MM

The first 3d model of a shape charge explosion was modeled by placing a charge on top of water, to capture that shape, then the next charge was placed 1 cm above the water, and so on, 2, 3, 4 cm. Eventually it creates a picture of how the metal is moving.

🇺🇸 should do that. testing on a giant steel plate. clean of any dust and debris or maybe concrete but a giant steel road plate would be better I would think. 🇺🇸
