Ok, here's what I know. Recent red flag (last 6 months). Alaska. A group (numbers unknown, at least 3) of F-15C models from Mountainhome AFB, ID went up against a pair of F-22s. F-22s were air to air load, internal AIM9-Xs and gun only. 15Cs were full air-air, mix load of 120C models, 9-Ms and gun.
I don't have the specifics as they haven't been released, but BOTH F-22s were confirmed kills. As I understand the circumstances, when the F-22s opened up to pop the 15s, they got pasted by a split off group of 15Cs from long range with a multi launch of 9-Ms and 120Cs. One kill for each missile. When they re ran the exercise, the 15s only got one with missiles, lost 4 jets, and popped the other 22 with internal guns.
This was an airforce combat exercise. Kill was designated by observers and judges. Most cases, a hard lock with a 9-M/9-X was considered a kill.
