Abstract
A rail gun barrel has a pair of opposed spaced apart rails separated by a pair of opposed stepped insulator members, which cooperate to define an internal bore. Interior body members surround the bore-defining components and fill the space between those components and an outer surrounding containment tube of varying curvature. A pressure cavity is provided in the interior body members on at least one side of the bore to load the outer containment tube, which because of its varying curvature, translates a circumferentially variable prestress inversely proportional to its curvature and is selected to match the particular loading scenario.
