Firstly this is meant for anything which flies above a certain altitude.Cruise missiles do not meet such high altitude interception systems. They just need a QRSAM battery. Just so you know, sub sonic cruise missiles are not the headache they uses to be. High resolution airbone 3D radars can track them like nobody's business. Now even ground based radars can "see" them at certain range. But still airborne aerostat with large aperture radar mated to either Akash SAM tasked with point defence of S-400 system will taken care of inbound Baburs. Plus even Rudras or Weponised Hawk trainer can be used to take these pesky things down. They only need to be vectored by an airborne system.
It doesn't matter if those IRBMS are going supersonic or hypersonic. They are bound to follow a ballistic arc which even a small mobile computer can calculate. And pls don't come up with theories that "Our warheads have nozzels built below them to evade ABM !" bcoz that has theory have been busted a million times. There just isn't enough room for thruster propellent to produce any effective change of trajectory. And moreover any thruster you see are to impart a spin on the warhead while re-entry. This gives it a gyroscopic stability and increases the CEP. At those speeds and altitude external contoll surfaces (if present) have to be super precise to maneuver the warhead. Even a deflection of 0.1 degree will send you 100s of Km off target.
Now coming to the most hilarious part of the post. Kid what do ya think, they will invite you to test there system? Going by your logic none of your ballistic missile, tactical nuclear warhead etc have been tested by a third party. All the test which you guys have conducted are in "Controlled Environment", hence everything you have reported ,if not outright false, is highly overrated !! Kid every system is designed with certain operational limits. And a system will fail if it is operated significantly beyond the range. That dose not mean that it is fool proof in its engagement envelop. Hence we define hit probability, fault tolerance and determine the SOPs around them. I would advise if someday you get a chance to be a member of a team which test these system, grab it with both hands and learn as much as possible. I am talking not only about these military systems but real life high performance systems. A lot of work goes on to test and certify these systems. Trust me I have some experience.
Bhai kabhi kabhi humare doston ke post padh ke yehi lagta hai DSI se ye duniya jeet lenge...!
I thought you guys have a billion ! Looks like you should change your culinary choices to ubiquitous family of monocotyledonous flowering plants or commonly known as Grass. But before you do so just keep in mind Babur is not be all end all system. And India won't show up to war with just S-400. There are a million ways to skin a cat.
Ummm...you know there is a very advanced system in place. It can be accessed by a simple web page. You go to that page, type in your query and press search and viola you get access to all the information you want. That page where you can access this system :-
