Obturator ring comprising two or more pieces each being a little larger than semicircle of the projectile obturator ring groove circumference. Each piece at natural position has equal or smaller radius than the radius of the obturator ring groove of a projectile; therefore, each piece expands to be in the projectile groove. Thickness and height of each piece is dependent on projectile's obturator ring groove geometry. The overlap and the radius ensures each piece performs its own grip function independent to the completion of the Segmented Obturator Ring (SOR). SOR seals the expanding propellant gases in the tube optimizing the effectiveness of the propellant while the projectile moves along the gun tube with SOR. After launch, the SOR is totally separated from the projectile minimizing drag effects on and maximizing stability of projectile to enhance dispersion impacts of the warhead.

1. An obturator ring to be secured to a projectile that is designed to be launched from within a gun tube having an inner wall and a muzzle, for sealing a pressurized gas within the gun tube during launch, comprising:a plurality of ring segments that overlap, prior to launch, in an engagement position around a groove formed in the projectile: wherein, during launch, the plurality of ring segments separate under the effect of the pressurized gas, and are forced against the inner wall of the gun tube to form a seal between the projectile and the gun tube; and wherein the plurality of ring segments become totally separated from the projectile upon exiting the muzzle of the gun tube.
