  • Wall breaching fragmentation projectile
    Patent number: 8943974
    Abstract: A wall breaching explosive fragmentation ammunition having a tungsten alloy nose cap with ceramic cone nose which make possible penetration into a hardened target with survivability of the warhead. The ammunition employs a unitary construction with fuze completely within the projectile's shell case. The ammunition has an external plastic rotating band which also encloses an induction antenna. The antenna may signal the fuze on a wire, through a hole in the shell case. The fuze signals may be fed through a gun barrel, then picked up on the antenna. The ammunition also employs a controlled pattern fragmentation mechanism incorporating a patterned plastic liner.

  • Wall breaching fragmentation warhead
    Patent number: 8316772
    Abstract: The invention describes a wall breaching explosive fragmentation ammunition and further a warhead having means for efficiently penetrating concrete and masonry walls, effectively delivering an explosive fragmentation case payload with minimum structural damage to the ammunition's projectile body. The effective wall breaching is achieved using an ogive-shaped, high strength, light weight boron carbide ceramic nose cone cap disposed adjacent to a tungsten alloy nose insert, at the fore of the ammunition. The projectile body is generally cylindrically shaped, preferably made of steel or aluminum to withstand expected forces in the launch environment. The ogive-shaped nose cone may be secured circumferentially to the projectile body with a rubber O-ring to ensure a tight seal.
