were tested in a towing tank to determine their resistance, motion stability, depth and course-keeping control, and ocean surface effects at high speeds. An optimal axisymmetric hull shape had minimum resistance and a mild pressure gradient enabling the development of a hull boundary layer suitable for placing control surfaces upstream of a single-screw propeller.

· Continued compilation of the variability of sea conditions and their statistics has improved the seakeeping design specification for surface combatants, and satellite ocean wave observations have provided timely guidance for ship operations. The basic understanding of ship response to the ocean waves associated with different sea states has improved the ability to design surface combatants with better seakeeping characteristics, less deck wetness, cost-effective shell plating and hull girders, and improved helicopter landing and takeoff operations.

This process was instrumental in the development of Mk 46 and Mk 48 torpedo hardware and software and to a succession of advanced weapons such as the advanced capability and Mk 50 torpedoes. · Basic research in hydromechanics and naval technical expertise have enabled advances in propulsor design through enhanced simulation and experimental methods that directly and indirectly reduced the noise signatures of Navy submarines, weapons, and tactical-scale vehicles.
