 The 2005 Base Realignment and Closure Commission committee report recommended the retirement of the block 30 F-16 Fighting Falcon, and the inactivation of the 170th Fighter Squadron.Despite challenges by the governor of Illinois in federal court, the aircraft began to be retired, and ultimately the US District Judge stated that there was not enough evidence to support that the region would suffer major harm by the closure of the unit.The last F-16 departed on 23 September 2008, marking the end of the flying mission for the 183d Fighter Wing.
