These missiles will be enough to secure and area roughly of the size of the National Capital Territory of Delhi, said an official.
While an the exact cost of the deal would be known only after negotiations are done, experts, on the basis of a deal struck between China and Russia, estimate it would cost around Rs.40,000 crore.

Another proposal cleared is to purchase 120 trawls from Russia at the cost of Rs.450 crore. These trawls, 120 in number, will be procured for T-72 and T-90 tanks of the army.
The official added that the defence ministry has asked the Defence Research and Development Organisation (DRDO) to develop indigenous trawls by the end of 2017.
Among other proposals cleared is procurement of 571 Light Bullet Proof vehicles for Rs.310 crore for the army, and developing two electronic warfare systems for the mountainous region.
