indians let's have some meaningful debate if you are capable of doing so:
my argument here is simple - it is never about whether you need it or not, india clearly needs this type of weapon. it is all about whether india/indians will be smart enough to design/master it. to have such weapons,
1. you need a White Cloud class NOSS system. To support the Chinese DF-21D anti ACC system, we launched at least 2 White Cloud class satellite clusters, known as YG-16. the last launch was on 25th Nov 2012. you don't have such satellites, and you don't the required rocket that can launch such satellite.
2. you need super accurate ballistic missile systems. To support that, basically you need a lot of launch tests to collect stats and gain experience. you need a flexible satellite navigation system that is under your full control. you don't have the navigation satellite network, you don't have the required rocket that can launch such satellite to form the network, you don't have a strong enough economy to back the R&D of such network. please note, we are talking about building & putting 30-50 satellites each at 5-8ton to operate such network.
3. you need super reliable ballistic missile technology. PSLV's success rate is 90%, GSLV is 20%. it would be a wet day dream to build weapon class missiles based on such reliability stats.
in short, to build and operate this weapon, you need to a pretty big reform to get ride of your highly ineffective government first.
