Tactics alone, and ECM, will help but will not stop the F-22. We can see them well before they can “see” us, and that means their ECM is marginally effective. (You don’t always drive around ‘jammin’ because its like turning on a flashlight in a dark room).
The enemy has to “see” our jet and they won’t. The bad guys will just start blowing up next to their lead/wingman and wonder where the shot came from.
F-22 is great BVR and doing grinder tactics by the F-22 ensures the likelihood of a merge is low.
If a merge does happen, the F-22 will smack’em hard.
Yabbut, we have a lot more F-15 and F-18’s out there that do not have the advantages of the F-22. I would worry about them, they are the likely ones to encounter a Flanker.
