By 1950, Yontan was redesignated as a parachute drop training facility because its runways were not suitable for large scale or jet aircraft operations.

By that time, local residents were started farming at the airfield with the tacit permission of the Air Force, and there were no fences installed on the base boundaries, except in administrative area.

In addition, control of the Yomitan Auxiliary Airfield passed from COMFLEACTS Okinawa to Commanding General Marine Corps Base Camp Smedley D. Butler on 9 October 1980.

Under the agreement of Special Action Committee on Okinawa (SACO) Final Report, the parachute drop training was relocated to Ie Jima Auxiliary Airfield (FAC 6005).

In addition to the USAAF units, Yontan Airfield hosted several Naval and Marine Corps air squadrons equipped with F4U Corsairs, PBY Catalinas and F6F Hellcats.
