How to shoot down a Raptor:
A: Keep your radio and non-AESA radars off.
B: Spot the Raptor on IRST.
C: Close in keeping outside the narrow 120 degree wide cone in front of the Raptor.
D: Park off his six and shoot him down with your cannon.
This will not work against an aircraft that has SAIRST, like say the F-35.
Maybe you should contact those guys flying F-15's against the F-22 in mach dogfights. Give them a few pointers... out of your extensive experience? Maybe those engineers and strategists who designed and built the Raptor should be informed that their brainchild product had a fatal flaw? Let's also make sure we don't have any enemy air bases or carriers which spawned miraculously on US soil... able to launch their fighters behind the Raptor's six o'clock and gun them down as you suggest.
Oh and let's just hope that enemy aircraft won't try and equip their fighters with high bypass engines for a low IR signature... otherwise they just MIGHT elude the sensors of say an F-35. Wouldn't want to be in that F-35 now, would we?
