Probably won't vaporize but at least the warhead will not fall in friendly territory despite the intercept.
You do know the closing speed between an outgoing missile and an incoming target will be enormous... any contact at all will lead to enormous damage of both items... a HE warhead will likely not survive the speed the missile is flying at even with a near miss that puts holes in the incoming target... the stress of moving through the atmosphere with multiple holes in its structure and most incoming weapons will break up and tumble and rapidly shed speed.
Anything with a large HE payload would likely explode and anything with a nuclear payload will likely break and fail to detonate even on impact with the ground.
A nuclear warhead is like a precision machine and bashing its side with a supersonic sledgehammer is more likely to break it and prevent it from ever exploding properly than to set it off.
I'm not suggesting that midcourse defence is perfect.
Midcourse defence is for cowards to be cheered on by idiots. Poland and Japan cheer on ABM systems on their territory, but mid course interceptors would be useless to stop attacks on their territory... they need end course interceptors like S-400 and S-500 though the latter could probably be used as a mid course interceptor too.
The US wants midcourse ABM systems in Poland and Japan and the Arctic Ocean because then they can use nuke warheads and all the shit will land in Europe and the Pacific Ocean and Canada respectively and they will be nice and safe and only have to deal with the few weapons that sneak through.
India does not have the distance from her enemies to even use midcourse interception because missiles flying over such short distances will either be going up very very high and then immediately coming down, or they will be operating on a depressed trajectory and never get high enough for there to be an interception outside of the atmosphere...
Several aspects of operating in the exo-atmosphere make midcourse defenses particularly vulnerable to countermeasures. In the vacuum of outer space, heavy and light objects released from a missile will travel on (nearly) identical trajectories. The lack of wind resistance allows objects with little structural strength to retain their shape. Taken together, these two factors enable a wide range of lightweight countermeasures.
And the first nuke you launch in amongst this big swarm of aparant targets that detonates will damage all of them and blow them off course in a way that would never happen with real incoming warheads... so then you will know... locate those interceptor missiles close to your border so the nuclear detonations happen over their territory... who are they going to complain to for launching what appeared to be a massive attack...
There are many possible exo-atmospheric countermeasures. Examples include replica decoys, electronic decoys, booster fragmentation, enveloping structures or screens, radar stealth, jammers, infrared stealth (low emissivity coatings or cooled shrouds), obscurants (radar chaff or aerosols), midcourse maneuvers, nuclear detonations to create electromagnetic pulse effects, and direct attacks on ground-based defense components (such as radars). Multiple countermeasures can be used in combination to enhance their effectiveness.
This is all true but over the distances we are talking about you would probably struggle to get an interceptor to their incoming missile while it is still outside the atmosphere...
The extended decision/intercept time, the coast period through space before reentering the atmosphere can be several minutes, up to 20 minutes for an ICBM.
Pakistan and China don't have any territory they could base missiles that would count as ICBMs that would still reach targets in India (and not over fly them).
This gives sufficient time to intercept an incoming warhead in the vacum of space.
The much shorter distances as I said means shorter ranged missiles will be used that may not even exit the atmosphere...
The midcourse phase allows the largest opportunity to intercept an incoming missile.
Only when the missile shot is from the middle of Siberia to the middle of the US of A. Going from China to India or Pakistan to India is a much shorter trip giving a lot less time and perhaps no time in space at all.
At this point the missile is no longer under power so it follows a more predictable path.
Why would you think that?
Even a MIRV warhead bus is powered and can manouver to release each warhead on board along a trajectory to allow them to reach their target.
As of now China has shown that its intent is to target several countries across Asia
I am sure they would say the same of you.... all these countries who draw parts of our territory in their maps...
So maybe it's the US that is nudging China to invade these countries.
Look at their belligerent activities recently... kidnapping Chinese CEOs and using Canada to do that... banning Chinese companies from contracts for no good reason at all, imposing sanctions... and then playing footsie with Australia and India to remind them whose side THEY are on... I am sure the US State Department will be shocked if any military actions start... because they are only interested in peace and democracy...
India is getting played.
Consequently, the decision will have to be taken by the Chinese communist politburo (and not India) as to whether they intend to follow the instructions being provided by the U.S
China is normally very sensible, but as you are probably aware... push the self defence buttons and anything appears justified... look at the shit hole Israel has dug for itself... it is fighting everyone.... what sort of life is that? Do they feel safer now they have their own country they can call their own and persecute their own minority populations in?
But they can't see that and they have a right to defend themselves... they stole the land they have with terrorism and violence and now complain to the UN and international community when the locals use the same method to get it back.
Exactly. And that's why I said in my previous posts that exo atmospheric/mid course interception is far more effective and safe than endo atmospheric interception. But then, you disagreed.
If you are using nuclear warheads then detonating them inside the atmosphere makes them vastly more powerful and effective... in space there is very little to no blast wave... it has nothing to travel through... just intense heat for an instant... and some serious EM waves... but inside the atmosphere it would be vastly more effective.
You do understand that an interceptor that hits targets outside the atmosphere essentially uses side thruster rockets.... and it is enormously complicated.
Inside the atmosphere a lot of missiles use sidethruster rockets to jump closer to the target at the last milisecond before they cross paths... but to shift the trajectory rather than just turn the nose of the missile the thruster needs to be at the centre of mass of the outgoing missile whose burning fuel has been shifting the centre of mass for the entire flight... when you have to move 5 metres to the left and you have a micro milisecond to do so then turning a fin just wont cut it... firing 20 side thruster rockets might get you that 5m.
In space the side thrusters are the only thing you can use to change direction... but there is no thin airstream to keep your nose pointed forward... your nose with radar and IIR sensors looking for the target that are critical to the intercept that must be kept pointing forward...
There are reasons exo atmospheric interceptors are not common.
The main one being if you smack into the target... whether in space or inside the atmosphere it is the closing speed that matters and the angle of interception... a side glancing blow of a missile going past will just damage it... a head on impact from a missile coming up from a similar location to where the target is and therefore where the target missile is actually heading is more likely to result in a solid contact and complete obliteration...
