This research develops scenarios and models to conduct analysis of alternatives for completion of various worldwide air refueling requirements with the goal of optimizing air refueling capabilities with a divested KC-10 fleet The intent of introducing the three proposed aircraft was not to advocate a specific airframe, but rather to examine different air refueling capabilities that varied the maximum fuel load available for receiver aircraft and average hourly fuel burn. While assuming a divested KC-10 fleet and a worldwide air refueling requirement of 20-50 million pounds per day, the study, using linear programming models, concluded that the Proposal C (large body) aircraft was the best selection amongst the three proposal aircraft introduced in this particular study. After examining each proposal aircraft's ability to deliver fuel to receivers under various sortie durations, the researcher also balanced the expected development and procurement costs. Proposal C aircraft was the clear preferred alternative in almost all cases. The only exception was in one scenario where Proposal B (KC-46B) aircraft was the best pick. The intent of the study was to stimulate thought while also providing Air Force leaders the requisite information to make the best informed decisions, thus shaping and molding the future construct of the Developmental Planning for the Advanced Air Refueling.
