Abstract

A plurality of discarding type segmented sabots are peripherally disposed rcumambient to the longitudinal axis of a subcaliber projectile to support the subcaliber projectile during launch. A prestressed notched bourrelet flange member screwedly attached to the forward sections of the sabot segments holds the sabot-projectile assembly together during launch. An aft bourrelet-obturator-slip ring assembly secures the rear sections of the sabot segments while transmitting only part of the rifling induced spin to the projectile. A self-adhering flexible base seal member is positioned in the aft end of the sabot segments to enhance efficient obturation of the propellant gases.
