C-12J
To meet the needs of transporting larger groups, the U.S. Army purchased six C-12J aircraft, based on the Beechcraft 1900C commuter airliner. One of the military C-12Js is used for GPS jamming tests at the 586th Flight Test Squadron, Holloman Air Force Base, New Mexico. Another is based at the 517th Airlift Squadron, Elmendorf Air Force Base, Alaska. Three were based at the 55th Airlift Flight, Osan Air Base, South Korea. They have been relocated to the 459th Airlift Squadron, Yokota Air Base, Japan. The remaining two are used by U.S. Army Aviation.
Don't see this Huron (C12J) up much.
