VORTAC decommissioned
Staff Sgt. Jason Hall and Airman 1st Class Steven Kohut, 51st Communications Squadron, ensure proper placement of the Tactical Air Navigation System, or TACAN, antenna on the trailer for shipping at Osan Air Base, Republic of Korea, June 4. The antenna was part of the Very High Omni-Range/Tactical Air Navigation System, or VORTAC, used to guide pilots safely to the airfield for approach in adverse weather conditions. The VORTAC was recently decommissioned as a new system was installed and control was turned over to the Republic of Korea Air Force. (Courtesy photo)
