Expeditionary Operations: intermediate engine maintenance alternatives

(7.) This assumption has stimulated considerable comment at briefings to various audiences. Some argue that current transportation times to locations outside CONUS can be substantially longer than 15 days, particularly for large items like engines. Others argue that planned changes to DoD transportation policies will result in shorter times. Given current constraints on military airlift and assumptions of how an MTW would likely stress the airlift system, the assumption of 15 days for one-way transportation time is retained.

(8.) This is more of a requirement than an assumption since more than 2 days of transportation time will affect the sortie generation.

(10.) This does not include the resupply transportation for spare parts and modules required for support of deployed JEIM shops.

(11.) Shaw JEIM was used because a large number of engines are repaired there and the distributions across all JEIMs of repair and ENMCS times were largely similar. Intermediate repair for the TF-34 is a mixture of quick turn and more comprehensive repair.
