Pakistan's response to S-400

Well, it is still two years before IAF gets its hands on the S-400. You should have read news on the forum. Furthermore, the max range of Raad 2 is classified. Finally, the OP also talks about a solid air defence in place.

Since we are talking about the element of surprise, what to you guys say about nuclear subs which won't need to evade the S-400 but completely cancel their viability as the S-400 would be lining up the land borders.

What is the learned members' take on this?
