Barak 8 ER in Azerbaijan

Sir, I really doubt the claim of intercepting incoming of Mach 27. Nowhere I have come across this claim for Phase II, I have seen claiming 12-15 Mach. Are you really sure bcz even S400 is not that much capable.

They are making a new target missile for Phase II with a speed of 6-9Km/s.
 
That's what I wanted to know that during mid course of ICBM(more than 8000 KM for Mach 20+), it would be too far away for any radar to detect unless we have airborne near the mid course range, even if we have radar to lock missile during entering phase, are we confident enough to intercept it with subsonic missiles when we have only 20 seconds to intercept. Shouldn't it be more effective if we have missile reaching Mach 7 in 10 seconds? or is it purely depend upon radar system and after certain limit missile(defense) range and speed will become useless?
I think missile interception is much easier than an aircraft interception, A missile will always fly towards the target or interception area, so if you fire a missile to India gate and if I am a tortoise then I have to calculate which direction you are coming from I will just go stand in the same direction to say boom ...ICBM will never fly at subsonic speed when it re-enters due to gravity it will fly faster. I always prefer Brahmos fired from MKI then the enemy will get few seconds to act.
