However this means that at 100km the rocket has only 600 m/sec, insufficient to intercept anything as fast as an ICBM,even with nuclear warhead.

S-500 missile will travel at 7 km/s. Is it enough to trget icbms ? because re-entry vehicle travel at 8-9 km/sec.

Low Earth Orbit (LEO) velocity is 7.8 km/sec. At this, or above this speed we are not talking about ballsitic missile, but a satelite.

So the reentry speed of a warhead can't be 7.8km/sec.The delta V generated by the rocekt engine can be as big, but few km/sec lost due to air friction.

I seriously doubt that the interceptor rockrt can reach 6km/sec speed.

Solid propelant can generate 2km/sec exhaust speed, so to reach 4 km/sec it need 1:7 empty mass:full mass ratio, to reach 6 km/sec it need 1:20 ratio.(maybe 2.3 km/sec,but dueto the small size I doubt it)

The rocket few metric tons, so I can't see enouth space for theese kind of values.

Additionaly, the decoys will trash the screen of the radar above 100 km.

The elbrus PC can't dierentiate the decoys from the warheads outside of the atmosphere.

under 100 km, due to the air friction the software can diferentiate the warhead(s).
