Capital Airport Air National Guard Station

The airport is home to Capital Airport Air National Guard Station, a 91-acre facility on land leased from the SAA. It is home to the 183rd Fighter Wing (183 FW), an Illinois Air National Guard unit operationally gained by the Air Combat Command (ACC) and State Headquarters, Illinois Air National Guard. Historically a fighter unit, the 183 FW consists of 321 full-time and 800 part-time military personnel.

183rd Fighter Wing (183 FW)

The 183 FW was directed to divest itself of its fighter aircraft pursuant to a Base Realignment and Closure (BRAC) 2005 decision and in October 2008, the last of the 170th Fighter Squadron's (170 FS) fifteen F-16C/D Fighting Falcon aircraft departed Capital Airport AGS for redistribution to other Air National Guard fighter wings.

Presently the 183 FW is tasked with augmenting Component Numbered Air Force (C-NAF) in both the Air and Space Operations Centers (AOC) and the Air Force Forces staff (AFFOR), A1 to A9. The mission of the 183 FW consists of supporting the assigned groups and tenant units with traditional military services as well as all services for force sustainment including civil engineering, personnel, logistics, communications, medical, security, family support, and all other host services.


The primary unit of the 183 FW is the 183rd Air Operations Group (183 AOG).

The 183 AOG is capable of augmenting C-NAF staffs worldwide, therefore affording AOG personnel the opportunity to train at various locations - CONUS and OCONUS. The role of the AOG is to assist the AOC in organizing, planning, and executing the "air war" in a contingency or campaign and assist the AFFOR staff in bedding down Air Force forces in the theater. The 183 AOG is aligned with Twelfth Air Force / AFSOUTH at Davis-Monthan AFB, Arizona.
