With respect to the S-400, much has been written about it and I won’t rehash it all here. How about we simply say that its detection range comes to the extent 600km and that its “engagement vault” has a 400km span and a 56km tallness. Actually, the S-400+Pantsir-S2 combo is the thing that at present ensures the city of Moscow! As it were, the Russians have truly sent in Syria the most impressive air protection capabilities on the planet.
For the “under the hood” specs of the SU-35S please see here. All that really matters is this: both as far as power(engine power , reach and radar power) and capability (amount and nature of weapons) the SU-35S is presently the most advanced military flying machine on the planet.
It is difficult to know what the Russians know, be that as it may, on the off chance that I may use that similarity, when you see a animal take up a run of a combat position you can accept that it has seen something which it is presently responding to.
What is clear to me is that the Russians have as of late significantly expanded their qualitative abilities and on the off chance that I consolidate this expansion is capacities with the sort of dialect I get notification from Russian authorities consistently I can just reason this is in response to Turkey’s moves.
I know, this is not really weighty, and I am not asserting that I came up with something new or unique here, all I am stating that what Russia does (deploying some to a great degree propelled systems) appears to authenticate what she says (that Turkey is planning something naughty and that the West might need to do something to stop this).
