IAF have superior A2A missles then ASTRA, which can change the course in mid way.
True, IAF have few most advanced missiles and almost all are available except few Chinese one which don't worth.
ASTRA is Head on missile....this means it will work only when target aircraft is flying towards the attacker.
Noo, Who told it to you? every missile have longer range when target is approaching toward it and shorter range when target is moving away from it. It is applicable to all missiles in the world.
When the target is coming toward the missile (HEAD ON) the
Relative speed of missile is higher (Missile speed + target speed). So it can be fired at a longer distance.
When target is moving away from the missile (Tail chase) the relative speed is lower ( Missile speed - Target speed). So it will travel shorter relative distance before the fuel is over.
Missile flight time is limited by the stored fuel.The distance covered is decided by Relative speed.
Its integrated with Active radar homing, this means that the aircraft with radar warning receiver like JF,F-16 & Mirage Rose would be aware that an incoming missile is approaching them.ASTRA will be tracked by AWACS, and modren fighter Aircrafts which r equipped with radar having range more then 50 KM.
And so is Raytheon AIM-120 AMRAAM,R-77,R-27,R-37, meteor,Derby which are considered best in the world.
It is true that Radar warning receiver will make target aware of incoming Missile. This gives them sufficient time to take countermeasures.but because of the accuracy and resistance to ECM of Active Radar homing method there may not be much they can do to avoid being intercepted.
The Radar on missile Tracks the Target,and the missile is typically going to be much closer to the target than the launching Fighter jet. During the terminal phase,the tracking can be much more accurate and also have better resistance to ECM Because as missile approaches the Target the Guidance will be more and more strong.Active radar homing missiles have best kill probabilities.
I feel even F-7PG with Grifo-MG radar can track it.
True, He will be aware that his death Warrant is issued and in mean time he can say Allah Hafiz on Radio Transmitter
