This monograph describes the new modeling approach developed to construct the CONUS CIRF network designs and presents detailed results from the specific analyses. The analyses are based on F-15, F-16, and A-10 aircraft force structure bed-downs resulting from the Defense Base Closure and Realignment Commission's 2005 recommendations. For the three aircraft types, all CONUS active duty bases, Air National Guard (ANG) installations, and Air Force Reserve Command (AFRC) installations possessing combat-coded or training aircraft, along with some Air Force Materiel Command (AFMC) bases, were used as locations to be supported by CIRF networks. CIRF network designs were constructed for aircraft engines (TF34, F100, F110), electronic warfare (EW) pods (ALQ-131, ALQ-184), Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) navigation (AN/AAQ-13) and targeting pods (AAQ-14s), and F-15 avionics line replaceable units (LRUs). This set of commodities was chosen because previous analyses (many of which were performed at RAND) had suggested that they afforded the largest potential savings from consolidated maintenance. Tasking scenarios considered in these analyses included normal peacetime training and readiness, Air and Space Expeditionary Force (AEF) deployment taskings, and major regional conflict (MRC) taskings.
