Luke AFB is projected to become the USAF’s primary F-35 pilot-training base and the largest F-35 base worldwide. U.S. pilots and foreign pilots alike will train there before deploying to combat units worldwide.

Luke officials expect additional F-35s to arrive a couple of times a month until the base has six squadrons of 24 planes each. They anticipate receiving about 15 more F-35s during the rest of 2014.
