One of the biggest considerations for an Aerospace Expeditionary Force (AEF), in terms of cost and airlift requirement, is the use of aircraft spares kits to support combat operations. To date, these kits are built on the assumption that there would be no resupply for the first 30 days of a contingency. However, with more efficient transportation and information resources available today, it seems logical that resupply would occur much more quickly. If so, the Air Force should be able to trim its wartime stocks of aircraft spares. This thesis investigated the effect of improving the logistics pipeline on the size and cost of Air Force mobility readiness spares packages (MRSPs). By using the Aircraft Sustainability Model (ASM), it was shown that order and ship time was the most significant determinant of kit size and cost. Also, through an innovative use of the Forward Support Location (FSL) Option, a potential for significant savings in both airlift requirement and spares costs was identified. In addition, evidence to support the efficiency of the 'pipeline on the fly' concept was presented. Under this model, aircraft spares would flow simultaneously from a depot as well as in a spares kit with a deploying unit.
