What the Chinese are doing is using IRBM against an aircraft carrier. I think it would miss the target if the Carrier is on full steam ahead at 32knots(50kms/hr). I don't see how an IRBM can strike an moveing target when after all the Re-enter Vehicle does not have a rocket motor to guide it.

Develop India's own anti ship/carrier ballistic missile to ward off chinese naval vessels.

Some of the missiles India has can perform the same function one I speculate that can do the same thing is a quasi cruise missile travelling at Mach 5.
Exactly. Our anti-ship missiles have the same genesis what Chinese obtained later from our friend :namaste:

Anyways this will now help us in developing countermeasures.

i dont know how this missile will work, since the missile needs to get target information from the satellite or ground station, their is area where missile will have communication black out, here more info on wiki

Reentry communications blackouts

The communications blackouts that affect spacecraft re-entering the Earth's atmosphere, which are also known as radio blackouts, ionization blackouts, or reentry blackouts, are caused by an envelope of ionized air around the craft, created by the heat from the friction of the craft against the atmosphere. The ionized air interferes with radio signals. For the Mercury, Gemini, and Apollo spacecraft, such communications blackouts lasted for several minutes.[1] Gemini 2, for example, endured such a blackout for four minutes, beginning at 9 minutes 5 seconds into the flight.[2]
For Apollo missions, the communications blackout was approximately three minutes long.[3] For Apollo 16, for example, pre-advisory data (PAD) for re-entry listed the expected times for re-entry communications blackout to be from 0 minutes 16 seconds after entry interface to 3 minutes 33 seconds after entry interface (a total of 3 minutes 17 seconds).[4] For the Apollo 13 mission, the blackout was much longer than normal because the flight path of the spacecraft was unexpectedly at a much shallower angle than normal.[4] According to the mission log maintained by Gene Kranz, the Apollo 13 re-entry blackout lasted around 6 minutes, beginning at 142:39 and ending at 142:45, and was 1 minute 27 seconds longer than had been predicted.[5]
Communications blackouts for re-entry are not solely confined to entry into Earth's atmosphere. They apply to entry into any atmosphere where such ionization occurs around a craft. The Mars Pathfinder endured a 30 second communications blackout as it entered Mars' atmosphere, for example. The Huygens probe endured a communications blackout as it entered the atmosphere of Titan.[1]
Until the creation of the Tracking and Data Relay Satellite System, the Space Shuttle would, like Gemini, Mercury, Apollo, and others, endure a 30 minute long communications blackout before landing. However, the Shuttle can communicate with a Tracking and Data Relay Satellite during re-entry. This is because the shape of the Shuttle creates a "hole" in the ionized air envelope, at the tail end of the craft, through which it can communicate upwards to a satellite in orbit and thence to a ground station.[1]

this is also the case with missile when the decent. so how does it work ???

missile has got very very small time to do this, as US shuttle has
These materials are designed to absorb large quantities of heat without increasing their temperature very much. In other words, they have a high heat capacity. During re-entry, the aft steering jets help to keep the orbiter at its 40 degree attitude. The hot ionized gases of the atmosphere that surround the orbiter prevent radio communication with the ground for about 12 minutes (i.e., ionization blackout).
HowStuffWorks "Space Shuttle: Return and Landing"

12 minutes for missile is very long time to have .

Its not going to have a data-link. It would be fire&forget which makes targeting all the harder. The ship is going to move several km from the point of launch so the seeker has to adjust within a few seconds otherwise it will overshoot the target. The problem of adjusting a Mach 10 warhead is two fold, the seeker would have to have superb optics, or powerful radar, that can withstand huge amounts of heat on reentry. 1) it is going to have to see the target at several dozens kilometres of altitude and 2) the seeker has to withstand temperatures of 1093°C. The casing would be too hot for an IR seeker so it would have to be ARH. Throw up several chaff clouds and it won't be anything but luck if it hits you. It will change CSG deployment as you would want more ships closer together to put up a very wide chaff cloud. Then there is always the problem of making radical course corrections at hypersonic speeds.
