I think that such KE-ATGM's are technically possible and plausible but i also think they are out of proportion between cost and effecience. KE rounds have 4 crucial points, if one of them sucks they become quite useless, since one effects all the rest of parameters, weight, velocity, angel to armor and hardness of tip, if one sucks the rest is worsten beyond a point which makes it good enough to penetrate even mediocre armor. With that parameters it needs a very powerfull boosting rocket with a following missile that controlls and adjusts the angle to the armor and sustains the hypervelocity that is necessary to make it effective. Speaking that this is supposed to be a KE (APFSDS) the design would quite interesting to have a tiny little spike as warhead with a wide body rocket that can bring it up to 2km/s.
I personally think based on on the information of the BK-31M and its tripple HEAT layout that it still holds more potential than we can get for same money and resources spend on KE development.
According to Fofanov's side (haven't researched much other sources), then the BK-31M with its tripple tandem HEAT warhead has the tip shaped charge to predetonate ERA, the 2nd charge that exploseds is the rear charge which is 2nd biggest and forms its penetrator through small opening of the middle charge and opens up some of passive armor of the tank for the main charge (middle charge) that has then an easy opening created by rear charge and therefor less armor to defeat.
Since the Rounds for T-64/80 and T-72/90 are shorter due the autoloader then any foreign tank, means that the Armata rounds can be longer and therefore have higher charge capacity. Fofanov also believes based on the picture that the main charge uses some alloy, since it differs by color from the front and rear shaped charge. HEAT rounds are nothing else but Kinetic Penetrators that use explosive to accelerate this tiny piece of metal to insane velocity and form it to a needle to penetrate armor and this fact makes newer Alloys with similiar molecular structure that is hard to disrubt by twisting or bending similiar to copper and should make a very formidable penetrators.
With longer rounds they indeed can or could fit longer or more shaped charges.
They have shown to work well, very in fact and that's why I support the whole thing. Tests showed the newer Lockheed models could penetrate 1000 mm RHAe *at TEN KILOMETERS while flying at 2000 (!) m/s the WHOLE way*. Any KE round today would struggle to do the same.... At point blank range! Of course they will cost more, but they are missiles after all. They have the advantage of being controlled and supposedly able to change targets. If testing over a period of many years, using many different models shows the concept to work, then by all means it must work well... You can find the designs online though it is a big PITA. Because the projects were never actually put into real motion information is scarce. I've heard that LM did produce a few hundred examples though.
Gotta remember that HEAT starts at a large disadvantage vs. KE when against modern-age armor. The M1A2's lower glacis should have more armor than the -31m's 800 mm of penetration based on info from the weaker-armored A1. This while the same lower plate will have 150 mm (or more) less RHAe vs. KE rods. Doesn't matter if it has 1 or 2 or heck even 4 charges if it can not penetrate. A lot of other Western MBT's have spaced armor as well, which as we all know affects HEAT in one way or another.
Yes and no... You want to prepare for the worst of situations when it comes to just about anything. Assuming the enemy will be riding on horses isn't gonna do anybody much good now is it? It would be no less effective than an equivalent HEAT round or missile.
Do you mean adequate or anything but? The latter would imply it wouldn't be...
Top-attack ATGM's are great until they have to deal with APS systems. They are slow, and much easier to destroy than a faster flying missile. Much like AShM's I'd like to add.
