    摘要： A weapon system employing encapsulated ammunition in which the pressure chamber, located axially rearward of the projectile, is longitudinally or axially offset from but in fluid communication with the propellant capsule chamber. This permits use of ammunition rounds having reduced length for given characteristics of prior rounds, resulting in lightest weight and improved bulk characteristics for the ammunition as well as associated weapon systems. This ammunition concept is adaptable to recoilless, partially recoilless and closed breech ballistic systems in a variety of arrangements.

    摘要： The method of making ammunition in which a steel metal skeleton is blanked or stamped to provide a central hub and radially extending fingers. The fingers are then formed to extend in a direction normal to the hub and in a peripherally spaced relationship with each other. The blanked and formed skeleton is laminated with a reinforced plastic material and the ends of the laminated fingers are necked. A primer is seated in the hub, a projectile is secured and sealed to the laminated fingers, and the laminated skeleton is loaded with propellants.
