Folded Ammunition is a unique concept in ammunition design that relocates the propellant charge from the conventional position behind and coaxial with the projectile to one beside the projectile. For a given energy output, conventional axially symmetric cartridges do not provide the most efficient geometrical shape for a minimum system parametric profile (system length, weight and bulk). Reconfiguration of the cartridge using the Folded Ammunition approach makes possible now what had previously been unattainable in the way of weapon/ ammunition system optimization.
