For me, not even the missile of S-400, but the radar itself is the biggest challenge. A pilot whose aircraft is getting painted hundreds of kms away from target by an enemy radar would be in a really difficult situation....when to prematurely drop his payload and start evasive maneuvers.......since he will never know when the SAM battery starts firing or what type of missile is being fired....what i have seen and experienced in near-real situations, my aircraft getting painted by a hostile transmitter is utterly dangerous which obviously calls for response actions......IAF experienced this alot in Op Swift Retort......Mirage 2000s and some other aircraft...
Not all but in most cases you will get launch warning of a SAM.
Pilot wont be staying in the threat bubble and wait for the missile to launch,he will do his job ASAP and go cold.
He will also be aware when is the SAM radar is on standby, active and in engagement mode.
So dont think a pilot is blind about the SAM radar.
What if india will launch missiles on Pakistani cities as response? Even you don't have protection to protect them!
It is not a so simple as you think!
Apart from this enemy can't guess what at the same time India is upto with its BRAHMOS....
I mean someone planning to destroy S400 with drones but doesn't know how many BRAHMOS already on the way to visit enemy bases....
During war it's not like only enemy will try to take this and that out.... both sides intelligence will be working with the same agenda...
Its not so simple as you think either,any missile launch from India be it cruise or ballistic will be considered as a nuclear weapon (even if it isnt carrying a nuclear warhead). You think the other side will wait for the missile to hit and see if it was nuclear or not? Obviously they will launch a nuclear missile in return.
what happens when you are painted by radars?
beeping in the cockpit?
what goes in your mind?
is it like being in front of sniper and he is just waiting to push the trigger?
When a radar paints you, you get a spike on your RWR,if you have an HTS you can also see status of the Radar on your FCR.
There is only one beep per spike
When the radar locks you,you get constant low noise
When the radar lets a missile at you,you get beeping sounds
A question came to mind. What was PAF doing in China during last Shaheen VIII exercise?
Countering S300
the moment you switch on that radar which will be like switching on a torch in the pitch black. the location will be made visible straight away and then you will be able to carry out the necessary SEAD option against it.
There is a reason why s400 is mobile system that is kept on the move and NOT a stationary system!
Even if the SAM radar is not active, position will be given away by the Search Radar and of course it usually active
That's the main purpose of SEAD, suppression of that radar and preventing the radar to go active meanwhile strike aircraft do their task
A few things I would like to mention:
Dont think S400 will be installed right at the border,it will be a bit deep inside india so range will be minimized
The bigger the range of the SAM,the easier it is to dodge,close range SAMs like SA3 are tough to counter than long range SAMs like SA 5 or 10
Slow moving targets like drones will be easily taken out by such SAM
S400 will be protected by a web of other SAMs
Most of the targets are usually located close to the border (DEEP STRIKE missions are a suicide) so those targets can easily be targeted without worrying about the SAM via SOWs etc (not forgetting SEAD packages)
PAF has extensively learnt how to counter S300 which will of course help against S400
Practically,its impossible for a SAM to target a very low flying aircraft such as Mirage.On paper its missile might be able to fly at 50 ft but in reality that's not possible.
