Yuma International Airport / Marine Corps Air Station Yuma — Yuma, United States

Yuma International Airport, sharing the code YUM with the adjacent Marine Corps Air Station Yuma, is a joint civil-military facility in Yuma, Arizona, United States. The Marine Corps station is one of the busiest air stations in the Marine Corps, hosting extensive fixed-wing training due to the region's consistently clear desert skies. Civilian operations at Yuma International share runways and airspace with military traffic, offering commercial passenger flights to Phoenix and other connections for the surrounding agricultural community. Yuma's location near the California and Mexico borders adds strategic value to the base's training missions. This dual-use arrangement makes YUM a distinctive example of coordinated civilian and defense aviation infrastructure in the American Southwest.
