F-16s being regenerated into drones
U.S. Air Force civilians Robert Bliven and Andrew Bakios, 567th Aerospace Maintenance and Regeneration Squadron perform maintenance on the first QF-16 being regenerated at the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base, Ariz., July 9, 2013. The conversion is slated to take approximately six months, or 180 calendar days, to produce an F-16 for delivery to Cecil Field in Jacksonville, Fla., where Boeing will install the QF-16 drone modification package.
