Yes. I’m not sure how many squadrons in total. But, I know that in addition to HI, the VA AirGuard also has a squadron at Langley. These were F-15 squadrons before making the transition to Raptors.
Yes; 192nd Wing VaANG.
Actually, VA Guard was flying F-16s, and they were based at the Richmond Airport. When the F-22s arrived, they moved to Langley (about 75 miles away) and became a partner unit with the 1st Fighter Wing.
