Thanx to u too Oqaab

I'll try to give more contributions the best I can.
It is nice to hear PAF will get the AWACS. These a/c will surely boost PAF capability. RMAF used to be heavily dependant on US equipment, but currently it is using Mig 29 and recenly closed a deal for SU-30 MKM from Russia.
One of the best thing about having AWACS is it gives jet fighters the ability to "ambush" the agressor. An agressor without AWACS back-up will be sitting duck even if the a/c is more modern than the defender.
In the ambush mode, the a/c can shut down it's own radar and rely totally on realtime datalink from AWACS to determine the position and heading of the agressor a/c. The defender a/c can then sneak up from behind the agressor to get a missile lock.
During this period, the agressor Radar Warning Receiver (RWR) will only display radar threats from the AWACS and not the defender a/c, and as the agressor own radar can only scan the forward sector of the a/c, in no way the pilot will be aware of the defender a/c sneaking up from behind.
If the defender a/c is equipped with Active Radar Homing AAM such as AMRAAM or R-77 ADDER, the pilot will realised it has been locked on by the enemy missile only at the very last minute, by then it will be too late to take any evasive action. ARH missiles can go active around 10 seconds before impact.
Even if the defender use Semi Active Radar Homing (SARH) such as Sparrow, the defender wingman can "paint" the target while the other launch it successively against enemy targets. However, radar "paint" will give sufficient warning to the target to take evasive manouver.
The other method is to use close range Infra Red Homing missiles such as the Sidewinder. The pilot only need visual target to launch the missile and don't have to paint target with radar. However, the pilot need to get close within visual range and risked being spotted first by the enemy pilot.
