And the diameter of the charge, which affects the required depth and thickness of the cone to achieve the Monroe Effect's focused blast. That can be counter productive to the aerodynamic shape required for effective flight, one reason why the WWII German Panzerfausts were short ranged, but very effective when they hit.
Additionally, the charge needs to be base detonated, though the noze fuze needs to be able to function even if it strikes the target at a less-than-ideal 90º angle. Typically, as in the Soviet PG-7 warhead or that of the M72 series US and British 66mm LAW rockets, that's accomplished with a piezoelectric crystal that provides a sufficient electrical charge to fire the charge's detonator when crushed into the target at flight speed. In the case of the RPG, the copper liner of the shaped charge is used as one electrical conductor to carry that electrical impulse for firing If the external body of the rocket is smashed into the charge liner, as when the rocket hits chail link fencing rather than solid plate, a short circuit of the firing circuit results and a dud round is the result. In practice, chainlink fencing will disable around 50% of the PG-7 rockets fired into it. M72 LAW rockets, being smaller, more often slip through, but are more often deflected, preventing a solid hit against the armor and thereby also resulting in a dud strike.
Not necessarily. The result sounds a lot like the resulting effect from an Israeli Rafeal *Spike-3* ATGM launcher missile hit. They're capable of either *fire and forget* attacks up close, or guided top-attack hits out to 4 KM when under operator guidance till impact; the NunTet-Dandy version is said to achieve hits out to 7.5 KM. And the Israelis know how to build weapons for killing tanks, even an Abrams. The things have been sold to Indonesia, Singapore and Finland, possibly others including Estonia and Serbia, and there's always the possibility that the Jihidists managed to divert one or more directly from Israel via Jordan.
A ChiCom B-40 warhead shaped charge, their version of the Russian RPG-2 rocket/launcher forerunner of the RPG-7.
But a pencil-sized hole with no spalling...?
Sounds like it went thru our best armor and hardly noticed it was there.
Suppose somebody built a rail-gun or coil-gun that worked outside the laboratory and launched a dense penetrator at ultra-high velocities...(?)
I'm thinking 20 km/s or higher....(?)
Does that mean I got a job in your freebooter motor-rifle battalion, Podpolkovnik Struwwelpeter? Platoon leader Lejtenant? GRU Tech intell? Ordnance support?
I'm thinking 20 km/s or higher....(?)
Or an APFSDS sabot round for their 2A42 30mm gun used on the BMP2 and BMP-3 Mech Infantry vehicles like the 25mm sabot rounds we have for the Bradley's Chain Gun, with performance somewhere between that of the US 25mm and the 30mm GAU-8 tank-killing Gatling Gun of the A10 *Warthog*.
There's a shoulder-fired 23mm Russian antitank rifle, too, a semirecoilless weapon something like an oversized M82A1 Barrett .50 caliber AMR. Maybe a really high performance round like the .50 Raufoos shaped charge has been developed for it, or maybe a light tripod-mounted 30mm version has been worked up....
I don't think we're quite to the point where a usable rail gun could be fielded in a package any smaller than roughly a 40-foot semitrailer truck or container, though it's certainly going to happen in the near future. But whether an electromagnetically accelerated projectile, a hypervelocity kinetic energy round, or an advanced small caliber chemical energy HEAT warhead, it's bad news for the crews in the Abrams...and worse news for those in Strykers.
Could be, though I think we'd have been at least generally familiar with the effects of one of our own warheads, even if reverse-engineered and upgraded [as we did with the Soviet SA-7 *Strella*] by a foreign source. The Russian Copy of the M72A2 LAW as their RPG-18 Mukha comes to mind....
But the Brits use the TOW in at least limited numbers as well, though they favour the MILAN for dismounted Infantry use. I wonder if they might have misplaced any new goodies from their boffins while they were in the area during Operation Telic.
