KT-1, basically a DF-21 varation, hit a satellite 900+ km away, travelling at 28000 km/hour, with an kinetic-head-on kill, and the satellite has a cross area of 1 m^2. Obviously missile with a CEP of 50 meter wont do this feat, more like it is some missiles with a CEP of <1 m.shiv wrote:The need for extreme accuracy to hit a carrier is essential ONLY if you use a conventional warhead. With a conventional warhead a miss even by 50 meters would make it useless - and as such it would require up to the second information.
If a nuclear warhead is used an airburst would be fine - and a miss by even 2 km would easily be covered by a 50 kt warhead. Since a ship sailing at 60 kmph (unlikely) would have sailed 2 km in 2 minutes - the last missile update could be given as early as 120 seconds before impact. Even at 6 mach (2000 m/sec) the last update could be given when the missile is 240 km away.
Of course that would mean starting nuclear war. In fact - if the Chinese could take out a carrier with a conventional warhead the US would be powerless to respond with nukes. But if they used the "easy route" and nuked the carrier as suggested above - then the US of course has the capability to finish China despite damage to itself. I think the Chingos (Chinese internet jingos) have got it wrong. China is trying to make a conventional warhead take out a carrier. And I am saying that they are not there yet and it is not that easy.
So still worry about China's KT-1/DF-21 is not accurate enough for this task?
For China, the primary techique challenge of deploying an AShBM system is not the accuracy of this advanced ballastic missile system, more like the development of a robust/surviving survery part.
