Approved for public release; distribution in unlimited. / The Littoral Combat Ship's (LCS) minimally manned core crew goal is 15 to 50 manpower requirements and the threshold, for both core and mission-package crews, is 75 to 110. This dramatically smaller crew size will require more than current technologies and past lessons learned from reduced manning initiatives. Its feasibility depends upon changes in policy and operations, leveraging of future technologies and increased Workload Transfer from sea to shore along with an increased acceptance of risk. A manpower requirements analysis yielded a large baseline (200) requirement to support a notional LCS configuration. Combining the common systems from the General Dynamics and Lockheed Martin designs with other assumed equipments (i.e. the combined diesel and gas turbine (CODAG) engineering plant) produce the notional LCS configuration used as the manpower requirements basis. The baseline requirement was reduced through the compounded effect of manpower savings from Smart Ship and OME and suggested paradigm shifts. A Battle Bill was then created to support the notional LCS during Conditions of Readiness I and III. An efficient force deployment regime was adopted to reduce the overall LCS class manpower requirement. The efficiency gained enables the LCS force to "flex" and satisfy deployment requirements with 25% to 30% fewer manpower requirements over the "one-forone" crewing concept. costs $60K. / Lieutenant, United States Navy
