Luke Air Force Base expects to get its first F-35 in the near future. Officials say they do not have a specific date but now believe the arrival of the new fighter could be as early as next week. Luke is a pilot-training base that has been selected for F-35 training, while operational units flying the F-35 will be located at other Air Force bases. Luke officials say they will hold a formal ceremony in mid-March to mark the F-35's arrival. F-35’s started arriving at the Marine Core Air Station in Yuma last year.
