    摘要: An underwater craft is considerably less likely to be detected by sonar if the underwater craft includes an outer hull as disclosed herein, which outer hull may extend in a longitudinal direction through a stern section, through a midship section, and through a bow section. The outer hull in the midship section may have a polygonal cross section. The outer hull of the midship section may also have curvature along the longitudinal direction throughout the midship section. A ratio of a radius of curvature to a total length of the underwater craft in the longitudinal direction may be between 5 and 1000. Further, a cylindrical pressure vessel may be disposed under the outer hull.
