    I thought they already did by using modified RPG warheads.
    I guess this works a bit better since it's purpose-made. Interesting that it appears to be 3D printed.

      rpg is shaped charge, efp is different and offers better stand of distances, which makes it attractive for terminal phase ai fpv's which they use to counter ew systems.

        I thought the difference was that shaped charge has better pen, but the jet is very sensitive to distance travelled and multiple materials (tends to dissipate).

          Modern shaped charges (post WW2) are not really particularly sensitive to air gaps these days. I can't imagine why you'd want an EFP over a shaped charge warhead for something you're going to fly into a tank anyways, you lose a lot of penetration for stand off capability that doesn't really seem to add anything since you can just fly the drone directly into the tank anyway

            A wider variety of warheads leads to more efficient use of materiel. They don't have to deal with tanks as often as they have to deal with MTLB's, motorcrosses and other garbage packed with infantry. I'd expect an EFP to travel deeper into lightly armored BMP's and remove more limbs than a regular RPG warhead would, all with a lighter load that can be carried with a cheaper drone.

              That's the one advantage I can see an EFP having, higher lethality upon a penetrating hit. From the footage I have seen though I'm not sure that BMPs and MTLBs are particularly survivable against standard RPG warheads anyway though

                It seems to me like these EFPs are a way to give an FPV drone a lighter payload, which increases its endurance. You also have to remember those turtle tanks being used as improvised APCs. These EFPs might be a way to punch through the outer layer of sheet metal without getting disabled by the jammers a lot of them carry.

              With bikes, ATVs and other open vehicles, wouldn't it be preferrable to have the detonation occur near the people. Or do you think the EFP's have sufficient tungsten ball coverage to deal sufficient injuries from frag outside the signal jammer range.

                It's probably a tradeoff between making at least 1-2 holes in everyone caught outside the vehicle, or killing 2 guys who absorb the blast, while the rest attempt to run away with soiled pants and mild concussions.

            Wdym by this, I don't see how modern conical shaped charges would be significantly less sensitive to standoff distance than older ones? Are you maybe conflating EFPs with them?

      You missed out on these anon. They're trying to get the GMLRS Alternate Warhead style of uniform fragmentation while making it stupid easy to produce. Anyone can 3D print the hulls and load them with BBs but the guys on the front lines shove the actual explosive and fusing in before loading them onto a drone.

      PSA:
      EFPs are all shaped charges but not all shaped charges are EFPs. Squares and rectangles. It pretty much just refers to a charge shaped in a specific way to take advantage of the wonky shenanigans that HE does when put into certain shapes.

      Ex
      >Conical shaped charges : ex RPG warheads, HEAT warheads in general
      >EFP: shallow cone or bowl, ex OPs pic, Javelin, NLAW
      >Sheet shaped ones: ex claymore mine
      >Linear shaped charges: demolition cutting charges

      there is a difference between a shaped charge and an efp, not sure what you're remembering but likely it is bullshit.

      . The penetrator needs about 4-5 meters to fully develop but then is able to go for +- 50 meters, giving the drone a standoff capability, it can be 40 meters from the target and just point at it, then detonate itself and the efp will hit the target. currently some armoured vehicles use drone jammers that causes signal loss when the drone is close to the vehicle, so they started programming ai into the drone for terminal attacks without signal, this new efp makes that all the easier, you don't need to hit the vehicle, just point in its direction and explode from a distance away.

    Why is there that conical cavity in front of the copper liner? Why not have just a flat nose?

        But I see no fuse nor a place to mount a fuse on. Is the fuse mounted on that flat nose with like double sided tape or something?

          I was wondering the same myself, it could be an anvil style impact detonator inserted into the back but that is just a guess.

            Fuze probably screws in from the rear.
            Either wired to metal contacts as we've seen, or even an inertial trigger which doesn't need to be on the nose, slamming into an object would cause the trigger to function.

            It's most likely triggered electrically from the drone, a nose mounted fuse would be in the way of the jet forming properly.
            You can see the hole in the middle of the screw in plug in the rear.

            Then why is there that cavity in front of the copper instead of just a flat wall?

                Oh so is it like standoff from the plastic wall? I guess that makes sense.

                I thought that he meant that the fuze would be mounted on the case like on an RPG rocket and that that amount of cavity was the fixed amount of standoff from the enemy armor plate which wouldn't make sense since usually these things use those wire thingies as remote fusing.

                Anonymous

                I'm guessing it's going to be impact fused so the nose cone hits and it detonates using that cavity to form the jet.
                RPGs are basically the same just with a little piezoelectric crystal on the tip that produces the electrical charge that triggers the detonator.

          Fuse is in the rear with the shaping charge, ding dong. The force goes rear to front, so, why wouldn't you see the obvious that the fuse and shaping charge would logically be in the rear?

          • 3 weeks ago
            Anonymous

            It's mostly semantics, but here the fuze is better referred to as "the initiator", "detonator" or even the "booster charge". Because there is several HEAT warheads/devices that do have front fuzes that send an electric pulse or even a miniature shaped charge jet back at the detonator of the main charge. 40mm HEDP, panzershrek and pg-7 are all examples off the top of my head.

                Yes, to give space for the jet to invert and form. Look at a xray flash of a jet or a CGI simulation, or think about how it physically works for 2 seconds.

                But if the fuse is not mounted there then what relation does that cavity have with the standoff distance from the armor plate?

                Anonymous

                You're dumb. The fuze doesn't have to be a tip mounted contact fuse as was previously mentioned. The cone on the front will still provide standoff distance as it doesn't magically disappear if you don't put a fuze on it. It will still be there between the shape charge and the item it is impacting. For instance some sort of inertial fuze set in the ream of the charge which initiates because of the impact. IMO they'll probably externally wire a small sensor of some sort from the back mounted initiating charge to the outside front flat portion of the cone though

              • 3 weeks ago
                Anonymous

                Okay, so if the fuse is mounted on the cone or an inertial fuse is used then the cone provides standoff distance.

    Honestly that HEDP is probably more useful outside of niche situations like a lightly armored vehicle with good frag resistance. Real armor would probably defeat it, super light, extra armor, or no armor and the HEDP makes more sense. Plus it can be dropped. Oh wait I forgot who were talking about vatnik APCs are literally small arms protection only, that EFPs probably gonna do some work
