Abstract

The objective of this project is to develop an innovative, low-drag, low-motion, 10,000-ton fast sealift ship concept capable of transporting 2,000 tons of equipment and 500 troops for 10,000 miles at 100 knots without refueling. To satisfy these requirements, at least a factor of five reduction in drag and in motino is needed compared with existing high-speed ship designs. Phase I of this study resulted in the development of several new vehicle concepts which might potentially satisfy these requirements, of which one was selected as a leading candidate. This leading candidate was explored in further detail in Phase I. The objective of this Phase II proposal is to further develop the ship design concept, explore areas of risk, conduct model tests to verify the theoretical performance predictions and demonstrate the feasibility of this new concept, and develop a plan leading to the construction of a prototype.
