Which category of airports includes those that are co-located with military operations?

The category of airports that includes those co-located with military operations is classified as Joint-Use Airports. This term specifically refers to facilities that are utilized by both civilian and military aviation, allowing for shared access and operational capabilities between the two. Joint-use arrangements enable a seamless integration of airport operations supporting both commercial and defense activities.

This classification is particularly significant because it involves a legal and operational framework that addresses the unique needs of both civilian and military air traffic. Joint-use airports often have designated procedures to manage the different types of aircraft and traffic operationally, ensuring safety and efficiency in a complex environment where both air travel and military operations occur concurrently.

In contrast, Class II Airports are primarily focused on general aviation and may not have military operations integrated. Shared-Use Airports incorporates various forms of sharing but does not specifically denote a partnership with military operations. Class I Airports are classified differently, typically indicating larger airports with higher passenger volumes and service levels that do not necessarily include military use.
