  • Low shrapnel door breaching projectile system
    Patent number: 8468946
    Abstract: A modified 40 mm grenade round designed to breach doors without throwing a significant amount of shrapnel into a building's interior or back toward the shooter. The modified round includes a forward extension on the ogive. The extension is rigidly connected to a thrust column which transmits an impact load directly from the ogive's nose cap to the striker on the fuse assembly. This configuration detonates the explosive charge within the projectile while the explosive is still well outside the door. This early detonation throws a pressure wave again the door's exterior, forcing the door inward.
