21 QF-4E's left at Holloman AFB, all belong to the 82nd ATRS/53rd WEG, only around 8 or 9 are now used for manned ops, the rest are all pure drones. They are scheduled to finish in December this year, assuming that the 'Zombie Viper' QF-16's are up to speed, but I understand there is still some teething problems with the QF-16's, so who knows, maybe they'll soldier on for a short while longer...
