The 30th Air Division (30th AD) is an inactive United States Air Force organization. Its last assignment was with Air Defense Command, assigned to Tenth Air Force, being stationed at Sioux City Municipal Airport, Iowa. It was inactivated on 18 September 1968.


Assigned to Air Defense Command (ADC) for most of its existence, the division's initial mission was the air defense of the upper Great Lakes region of the United States. The 30th equipped, administered, trained, and provided operationally ready forces to the appropriate commanders for air defense. The division trained attached and assigned units and supervised and participated in numerous exercises such as Kiowa Knife and Mandan Indian.

Moved to Sioux City, Iowa in 1966 as part of an ADC reorganization and became responsible for air defense a large area of the upper Midwest after the inactivation of the Sioux City Air Defense Sector. Assumed additional designation of 30th NORAD Region after activation of the NORAD Combat Operations Center at Cheyenne Mountain, Colorado and reporting was transferred to NORAD from ADC at Ent AFB in April 1966.

The 30th administered and trained subordinate units, and participated in numerous air defense training exercises. In addition, during the 1960s it supervised training of Air National Guard units with a pertinent mobilization assignment.

Inactivated in September 1968 as ADC phased down its interceptor mission as the chances of a Soviet bomber attack on the United States seemed remote, its mission being consolidated into North American Aerospace Defense Command (NORAD).
