There is no records of use in operational wars,although it is suspected to have been used in the Gulf war. But there were a few exercises which demonstrated the capabilities of a stealth aircraft (LOW RCS) over conventional one.
Fourteen F-22s of the 94th FS supported attacking Blue Force strike packages as well as engaging in close air support sorties themselves in Red Flag 07-1 in February 2007. Against superior numbers of Red Force Aggressor F-15s and F-16s, the F-22 maintained air dominance using eight aircraft during day missions and six at night, reportedly defeating aggressors efficiently and with speed. Further, no sorties were missed because of maintenance or other failures, and only one Raptor was adjudged lost against the overwhelming defeat of the defending force.
