The invention provides an improved propellant system for firing projectiles in large caliber guns. Strips of energetic propellant are placed in the cartridge case so that the lengths of the strips are parallel to the length of the cartridge. Preferably, the strips are placed in a radially symmetric pattern. The strips provide passageways that allow ignition gasses to flow radially in the cartridge case and along the length of the cartridge case.

[ What is claimed is:] [1.] A propellant system having a cartridge case and a projectile associated with the cartridge case, said projectile having fins projecting substantially radially from the center of the cartridge case toward the periphery thereof, comprising:a plurality of strips made of energetic propellant material;each of said plurality of strips having a width and a substantially uniform thickness;all of said plurality of strips being arranged around the periphery of the cartridge case with the widths thereof being directed inward;said strips arranged in a plurality of groups with each group associated with one of the fins; andthe strips in each group being parallel to the associated fin, whereby the intersections between adjacent groups of strips creates spaces to provide for flame propagation and for uniform gas pressure increase as a result of the burning of said strips.
