ABSTRACT:
An ultra light weight sabot for a subcaliber projectile comprises a sabot having three reduced mass segments each incorporating driving grooves at their inner diameter, an aft bourrelet, a central cavity beneath the aft bourrelet and an outwardly directed projection forward of the aft bourrelet to support the forward end of the projectile as it travels through a gun bore. The aft bourrelet has a balloon type obturator thereon which also fastens to the cartridge case. A bore extending through the obturator and the aft bourrelet into the annular cavity equalizes pressure between the case and the annular cavity to assist in sabot segment separation from the subcaliber projectile.
