AWACS detects threat way before it becomes a threat, and directs assets towards it.
It cannot outrun or out maneuver a fighter jet or a missile, no matter which plane is being used.
For Pakistan the Saab-2000 platform costs 800 usd per hour to run.
A jet powered same sized plane will cost 2000 usd per flight hour.
An IL-76 costs 15000 and above per flying hour.
So for us , finance is also an important factor for choosing the plane.
That's actually what I meant when I said it's an affordability problem.
