The complete round consists of a symmetrical forged C60 steel projectile body, internal solid-fuel rocket motor and HE filling. There are 6 gas check rings spaced around the waist. The rear taper is considerably thicker than normal and the tail fins are close to the body. The central cartridge container extends behind the fins and the horse-shoe shape increments are fitted around it.
