Operational Maneuver From the Sea (OMFTS) and its implementing concept, Sea Based Logistics (SBL), stress the need for logistically supporting forces ashore directly from a sea base. This study analyzes the capability of a current LHD-class amphibious ship to sustain a force deployed ashore through direct ship-to-objective movement of sustainment requirements. This study presents a baseline simulation model to estimate the ability of a LHD to deliver the required logistic support. Experiments were conducted with various scenarios and distances between the deployed forces and the nominal Sea Base (LHD). Sensitivity analysis was conducted to determine the effects of various parameters on the ability of the Sea Base to successfully accomplish the given scenarios with the specified conditions. Results indicate a substantial increase in the number of aircraft, operational availability of those aircraft, and/or a substantial reduction in sustainment requirements are needed in order to successfully accomplish the stated scenarios of this study. The results of this study could support the design of future LHD-class ships.US Navy (USN) autho
