All these UAV's and drones are all disinformation so CHina and other countries waste their defense budget on competing, the US ones are not operationally capable. All these strikes in Waziristan are actually F-22's testing their new SDB's.
Just to ad some info however : prod line was opened from 97 to 2011
Operational tests ended in 2004
Between 2004 and today did you remember a war where true air dominance was needed ?
There is none
So no combat missions for the F22
