Oh please! You think S-400 is a magic system which can do anything? HTK intercepts do not occur out of thin air - entire system is designed and optimized for this end, from scratch.
Only Russian 776N series interceptor suite can achieve HTK, and this is a recent accomplishment for Russia. Only S-500 will be equipped with this interceptor suite, and S-500 have the necessary sensor suite (radar and communications) to facilitate HTK intercepts.
9M96E and 9M96E2 are HTK. 48N6E and 40N6 use explosives.
77N6-N series are HTK in the same category as 48N6E and 40N6.
Also, HTK is entirely dependent on the capability of the missiles themselves, and not the radars. The S-400 will also be equipped with 77N6-N series.
People can be honest sometimes, and he is a military professional. I would give him the benefit of doubt.
Unless you have designed and tested S-400.
I know that you are a fan of S-400 and have a high opinion of it but you take its speculatory hype at face value and do not acknowledge limitations of the system.
I also have high opinion of S-400 and I consider Indian inductions as a destabilizing factor for South Asian security paradigm, but I believe in authenticity.
Nothing he said is correct.
For example, he says we are not getting the 40N6, but we are. This is confirmed information.
He is telling a different story with the mobile mast. There are plenty of vantage points for the S-400's radars along the border, without having to use the mast.
Then he goes on to talk about hypersonic warheads, Pakistan has none in its inventory. And, to date, nobody has hypersonic warheads operational or hypersonic manoeuvrable missile defence. So he is just bringing up non-issues with the mobile mast and the anti-hypersonic capability.
And finally, his information about the number of targets tracked and engaged is obsolete.
Ok, so 10 battalions is 80 Launchers? Each S-400 Battalion has 8 launchers.
The listed price is 400 Million USD per 8 launcher Battalion.
Thats 9 Battalions in 5.4 Billion USD
It's 8 to 12 launchers. So we don't actually know how many launchers have been ordered.
And your calculation is wrong there. If the listed price for each battalion is $400M, then for $5.4B we will get 13.5 battalions. You calculated for $600M per battalion.
The Chinese ordered 6 battalions for $3B. So for $5.4B, we may get 10.8 battalions, or 10 battalions, at $500M each.
But originally, the S-400 deal was supposed to cost us over $6B. So that puts us at 12 battalions, which we haggled down to $5.43B. Plus, the possibility of doubling the purchase in the future.
So anybody's best guess should be 10 battalions at the minimum, since that's what 5 regiments means. The Chinese ordered 2 regiments with 3 battalions each.
