A spherical convex pusher plate member is positioned intermediate the rear end of a subcaliber tubular projectile and the forward section of a cup shaped sabot carrier to improve the ballistic performance of the projectile by reduction of a parasitic weight and faster separation of the carrier after launch. Propellant gas pressures acting on the convex spherical section of the pusher plate causes deflection thereof sufficient to force the sabot to loosen from the projectile to provide an improvement in projectile velocity.

An Apparatus for launching a spin stabilized hypervelocity subcaliber tubular projectile from a gun which comprises: sabot means for obturating said subcaliber projectile passing through the barrel of said gun and for imparting rotation to said projectile which includes; a cup shaped molded plastic housing having a spherical concave inner closed end therein; and pusher plate means fixedly molded within said spherical concave inner closed end of said housing intermediate said sabot means and the rear end of said projectile for increasing the velocity of said projectile by reducing the parasitic weight of said pusher plate means, for aiding the removal of said means from said projectile after said projectile exits from the bore of said gun and for absorbing stress imposed on said sabot means and said projectile due to launch forces.
