In this study, Data Envelopment Analysis DEA is used to calculate Air Mobility Command AMC airlift fuel efficiency for C-17 aircraft. Fuel is a strategic asset for the United States Air Force and suitable alternatives are not yet feasible or available in the quantity required. The Air Force is pursuing several initiatives to conserve energy and operate more efficiently while sustaining the same level of effectiveness and safety. In order to manage these initiatives, it must measure how well it is doing. To measure airlift efficiency, the AMC Fuel efficiency Office established a 7 factor weighted Fuel Efficiency Index FEI. To produce a monthly score, AMC assigned weights for each factor. DEA does not require such a prior assumptions and finds the best set of weights that will help each mission to represent itself in the best manner. The results showed that DEA and FEI agree in trends but a DEA Slack-Based Measure better differentiates inefficiencies than other methods used in the study. Also, the results showed that for current Air Mobility flights, at least 10 input excess or output shortfall occurs each month.
