Every five years, KC-135 Stratotankers undergo depot maintenance by the 564th Aircraft Maintenance Squadron, Tinker Air Force Base, Oklahoma.
The process includes stripping off an aircraft’s paint, removing the engines, dropping the boom, removing and replacing deficient parts, and any upgrades as necessary. It takes an average of 125 days.
