The paper begins with a description of access design as a key element in effectiveness of the naval ship. The process of integrating access requirements with competitive subsystem requirements is then discussed. Next follows a discussion of the design methodologies used in each aspect of shipboard access which includes analysis and evaluation of the network of passages, vertical accesses, and access openings with regard to personnel flow, equipment removal, stores “strike—down,” emergency egress, and unique requirements for specific ship types. In addition to discussing existing methodologies, the paper concludes with a summary of potential areas of further improvement in access design.
This paper begins with comments on accomplishments in sealift and a summary of current problems in fast sealift. These include: few fast sealift ships in the inventory, a diminishing industrial base capable of producing such ships, and a lack of production programs to build ships that would increase our national fast sealift capability. The paper discusses strategic mobility concepts and highlights system interactions and linkages in moving war materials and replacement forces from depots and factories to the front lines. From this foundation, the paper then discusses operational requirements “pull” as related to analysis and allocation of performance among components of the strategic mobility system. Sealift technology options are characterized and performance potential of these options are described. These characterizations include speed, ship lift capacity, equal cost fleet size, and fuel demands for a range of speeds from 24 to 50 knots. Performance potential for each option includes the total fleet lift capability stream over a 100‐day time span for a notional mission with and without an assumed rate of attrition. Alternative program plans are described for each technology option addressing technological risk, system and component development needs, design requirements, production strategies, acquisition time lines, and resource requirements. The paper then revisits the operational requirements from a technologist's perspective. In a technology “push” approach, a set of practical and achievable requirements are selected that could be the basis of an effective and cost efficient production program for fast sealift ships. Finally, the paper concludes with a call to action that would suggest a modest reallocation of transportation resources to establish and sustain a fast sealift production program, sustain a sector of the maritime industrial base hard pressed by a lack of commercial shipbuilding, and achieve a relatively near‐term increase in fast sealift capability at sea.
This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG‐51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG‐51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG‐51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.
This paper comments on the need for additional medical capability in the Amphibious Fleet and reviews the Medical Unit, Self Contained, Transportable (MUST) System. MUST is a completely self‐contained collapsible modular system which to transported on the amphibious ship in a stowed configuration. After “off‐load” of combat cargo the MUST System is expanded and deployed within the ship. This paper comments on the feasibility of this concept, presents possible arrangements of modular facilities on the LSD and LST type ships, and discusses improvement of existing “built‐in” faculties aboard the LKA type ship.
