Tinker refurbishes F-22 air turbines
F-22 Raptors fly in formation. Air turbines used in the F-22s are now serviced by the 550th Commodities Maintenance Squadron at Tinker Air Force Base, Okla., as part of a new cooperative agreement with private manufacturers Lockheed Martin and Honeywell. The squadron will maintain more than 30 components from the high-tech air superiority fighter. (U.S. Air Force photo/Staff Sgt. Samuel Rogers)
