Totally Destroying AR500 Steel Armor With An EFP

Welcome to EFP vs Blank! Where the blank part is random targets we hit with an EFP aka explosively formed penetrators and we see what happens. These lovely devices can punch through even the thickest of hardened armor like it was a walk in the park. We have been experimenting with EFPs extensively and this is our refined prototype. It's performance has been stellar so far.
Today's target is a plate of AR500 steel graciously donated by @grizzlytargets808. These are commonly used on ranges as reactive targets as they make a lovely gong sound when struck with high velocity projectiles. The steel is very hard, rated at 500 Brinell. Hence the 500 in the name AR500. These targets can withstand a ridiculous amount of abuse, but can they withstand an EFP?

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.

@nathanjones2584 2 месяца назад

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).

Unlike a standard shaped charge with a copper cone the standoff distance of an EFP can be much farther because the slug formed is more stable and cohesively than from a cone shaped liner.

@pugz3230 2 месяца назад

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.

@TastiLead Месяц назад

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!

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.

@joewoodchuck3824 7 дней назад

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.
