US Classification:

102477, 102488

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.

Abstract:

A modular hand grenade design that permits the use of compressed powders such as A-5. The hand grenade body is split into two main components—a base/sleeve and a nose cap. These two main components contain the explosive. They are loaded with explosive while still separate. The explosive is loaded into the base/sleeve and compressed to form a solid. A core sleeve is attached to the base to form a void inside the explosive where the detonating portion of a fuse assembly can be placed. Explosive is likewise loaded into the nose cap and compressed to form a solid. The nose cap is attached to the base/sleeve assembly. A fuse assembly is then attached to complete the grenade.
