THREE WINNING DESIGNS--FDL, LHA, DD-963: METHOD AND SELECTED FEATURES

A systematic approach to the design of naval ships is presented with examples chosen from three ships, Fast Deployment Logistic Ship (FDLS), Amphibious Assault Ship (LHA), and DD-963 Class, which have been developed under the Contract Definition (CD) process. The design approach presented in this paper provides a framework which attaches quantitative merits related to ship system performance and cost to each design feature chosen and minimizes dependence on subjective opinion. First, a design philosophy is derived, to be used as a "value system" and a mathematical criterion. Next, the paper describes the approach for the derivation of a feasible ship concept from its physical (external and internal) definition standpoint as well as several other standpoints, such as stability, subdivision, watertight integrity, and structural adequacy, using the DD-963 as the example. The paper concludes with a selected subsystem tradeoff study from two of the three ships: (i) the cargo handling system of the FDL, and (ii) the waterborne portion of the LHA's assault system. The paper demonstrates that given a small number of key performance requirements, the application of a disciplined approach results in development of an optimum ship design for which all functional and physical characteristics, to the detail equipment level, are consistent with each other and provide the requisite performance.
