Abstract: A cartridge assembly (i) for weapons, said cartridge assembly including: a tubular body (a) having a central longitudinal channel containing a plurality of electrically fired projectile assemblies (b) in axially stacked orientation, each comprised of a propellant layer (c) and one or more other layers. At the base of the cartridge assembly (i) are routing electronics (f) to control sequential ignition of each propellant layer (c) subsequently launching an aerodynamic projectile (h) created by the incident pressure wave with favorable ballistic qualities derived from the characteristics of the projectile assembly (b).
