Airwing
You are missing both force multipliers of AAR and AEW/AWACS. The Harrier is good especially coupled with AIM120 to take away its lack of supersonic speed but you need AAR to extend CAP time and AEW/AWACS to detect and control them on to the low level threat.
K/M/CV-22s for tanking, and EV-22s for AEW. Not as good as fixed wing assets, but better than nothing.
