Abstract
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.

16. An underwater craft comprising:
-
an outer hull that extends in a longitudinal direction through a stern section, a midship section, and a bow section, wherein with respect to a plane that is transverse to the longitudinal direction the outer hull in the midship section has a polygonal cross section, wherein the midship section has a length extending in the longitudinal direction, wherein the outer hull has curvature along the longitudinal direction over the length of the midship section; and a substantially cylindrical pressure vessel disposed under the outer hull. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
