Overview
The command has sole responsibility for ensuring the air sovereignty and air defense of the Contiguous United States (CONUS), United States Virgin Islands and Puerto Rico. As the CONUS Region (CONR) for NORAD, the bi-national North American Aerospace Defense Command, CONR provides air defense in the form of airspace surveillance and airspace control.
1AF (AFNORTH) is also the designated air component for the United States Northern Command (USNORTHCOM). USNORTHCOM's area of responsibility includes the continental United States, Alaska, Canada and Mexico, and its air, land and maritime approaches.
The command is unique in both its mission and composition. With the transfer of responsibility for continental air defense from the active duty component of the Air Force to the Air National Guard, 1 AF became the first numbered air force to be made up primarily of citizen airmen.
