A misconception. The kinetic energy is contained within the particles of the projectile. Upon impact a hardened penetrator will not magically disperse and convert all its forward momentum into an outward spread like a conventional explosion...
This is true, which is why this weapon has six separate warhead buses and for each warhead bus there are 6 penetrators.
Once you have penetrated the heavy protection the problem is causing damage... military forces around the world are happy to use full metal jacket ammunitions for small arms because although the lethality of the ammo is massively reduced compared with soft nose or HE rounds, you can make them lethal enough with multiple hits.
That is what this missile is doing... multiple hits using powerful penetrators.
If you play the game War Thunder you will know that hitting a tank with a penetrator that even manages to go right through might not kill all the crew or set off the ammo or the fuel... the only solution is hitting it multiple times... which is what Hazel does.
I don't think FAE warheads would work at 3km/s, so for soft surface targets using large slabs of metal broken up into tiny cubes or spheres that are shattered a certain height above the target would be devastating... like an airborne claymore with fragments moving much faster than any claymore ever made. Of course the small fragments will slow down very fast so the altitude it fragments is critical... and at the end of the day a nuke warhead is always going to be the best option for such targets anyway.
There are no traces of the Oreshnik attack. Perhaps there were only decoy warheads. There was no kinetics dunno Unless some penetrators have penetrated the ground deeper. There is no visible damage on the surface. Which is strange, because even a practice warhead should have made a big crater.
Hmmm... so if there is no damage.... why the artificial cloud cover for a day or two?
Plenty of time to patch holes of course... a tank that is penetrated by APFSDS rounds has a 50mm entry hole usually... cover that with a box or some spare track link and you might think the tank has never been hit at all.
You have to ask yourself why would Russia bother if the damage was superficial... just land them somewhere more public where thousands of people with cameras can record the attack.
This is not a toy, this is a weapon of war and is intended to be able to be used before WWIII starts.... perhaps its impact might even prevent WWIII... but the west is lying and covering things up so the escalations will likely continue.
Russia (like the Soviet Union before it) has quite a few models of operational ballistic missiles (ICBM, IRBM, SLBM, etc.).
I don't see why the new Oreshnik has to be based on any of them.
They don't have to base it on an existing design, but if they do the existing design will be an ICBM or SLBM with a much longer range... so simply taking a rocket stage out will achieve the range and performance they are after without a lot of work.
Of course they could simply load a very heavy warhead on board which could reduce the effective range of an ICBM down the IRBM ranges.
If the new weapon is based on stages of in service in production weapons that means it is already in production... the only difference would be the different payload and launch vehicle, which would be quick and cheap and easy to put into production.
With a flight speed of mach 10 they might replace rocket stages with scramjet powered stages and make them much much smaller and lighter...
A KE weapon is thus only effective against targets with concentrated energetics (ammo, fuel, power plant) that you can readily identify and target.
Large bits of machinery like huge ship engines or large machines on the ground don't cope well will large holes being punched into them, and deep underground any sort of cave in can be problematic.
Introducing a large penetrator into a bunker structure can be very destructive, though obviously making 6 or 36 holes in a bunker has more effect.
It is the worlds first Cluster APFSDS round... from the sky.
I'm sure another demonstration can be arranged. Daytime this time, in a location that's harder to cordon off. With advanced notice, so that everyone has their phones out for the occasion. And more westwards as well, closer to NATO territory. A lot closer.
Reaction from the west and Kiev I would say a repeat performance is almost inevidable... they didn't have it... then they use it... they only have one... then they use it again... they only have a very small number and are afraid to use them... they use five... they need to be banned by international law... lets call it IFU instead of INF... it could stand for I Fucked Up... can we have a do over?
