The Navy has experimented with many ways to improve the producibility of naval ship designs. In terms of effectiveness - does the ship do what it is supposed to do - the Navy has been reasonably successful. However, in terms of efficiency - are the ships efficient to produce and own - there is still much room for improvement. Design for producibility – being able to efficiently produce a warship - must start during the earliest stages of concept design and continue to be addressed during the subsequent pre-production processes. However, many early stage naval ship design engineers either do not recognize this need or do not know how to design for producibility. A number of improvements to early stage ship design capabilities are being developed in order to make the process both effective and efficient. This paper addresses the critical stage of the collaborative Design-Build-Own process of initially sizing the hull during concept design. The author proposes the development and use of more physics-based design tools during concept design, such as those being developed under the DoD High Performance Computing Modernization Program’s Computational Research & Engineering for Acquisition Tools & Environments (CREATE) – SHIPS Project. These new ship design methodologies will enable conceptual design engineers to adequately size a ship to meet military performance requirements and to have a low enough ship density to ensure successful ship construction outcomes. The director of a Netherlands’ shipyard which designs and builds surface combatants recently stated at a luncheon of the American Society of Naval Engineers (ASNE), “We learned a long time ago to give ourselves enough space to build a ship – steel is cheap, air is free!”
