Again if I remember correctly from my discussions with the F-22 demo pilot in KOSH there are no guns on an F-22, but it can carry an underwing pod holding a large 20mm one. Not sure if a on high altitude intecept mission it would carry an underwing pod. Nevertheless the Pentagon said the F-22 used a "a single AIM-9X supersonic, heat-seeking, air-to-air missile" , the "heat seeking part" is somewhat ironinc here , and the supersoninc probably overdone too, but they got the job done at the exact location they wanted to , so congrats. If they missed and it was outisde the 22 Km sovereingn airspace limit it would have been shooting down an aircraft in international airspace, a totally different ball game politically....
