DESIGN TO COST -- A VIABLE CONCEPT IN NAVAL SHIP DESIGN

The "Design to Cost" concept is investigated from a practical viewpoint by analyzing the impact this design philosophy has had on recent Navy ships. The Guided Missle Frigate design is used as a case study to determine differences between Naval ships designed to cost and those conventionally designed. The case study includes an investigation of naval architectural features, performance, cost, and an analysis of the design "trade-off" decisions. The analysis of the FFG-7 design pointed out a number of significant differences in this "Design to Cost" product. A substantial weight and cost saving was realized due to the highly constrained design environment. It is estimated that the FFG-7 would have displaced about 1500 tons more (40 percent) if it had not been for the "Design to Cost" procedure. This saving was achieved primarily as a result of a reduction in performance requirements. The future of "Design to Cost" as a viable design philosophy for naval ships is discussed. It is concluded that the Navy must follow this concept in order to hold down the cost of combatant ships, but that a decrease in overall ship performance must be expected.
