40mm HE Door Breacher

One of the most interesting new products from Chemring is the 40mm HE Door Breacher. This has proven to be an innovative standoff Door Breaching cartridge that can be fired from single- or multi-launch 40x46mm grenade launchers and minimizes fragmentation hazards on both sides of a door. This 40mm low velocity cartridge is utilized for rapid entry through locked doors, without risk of injury to the shooter. It has demonstrated breaching capabilities against both inward and outward opening doors from distances of 15 to 60 meters with no fragmentation back at the shooter.

Anti-Personnel Obstacle Breaching System (APOBS) MK 7 MOD 2

APOBS is a self-contained, one-shot, expendable linear demolition charge, capable of safely clearing a footpath through anti-personnel mines and multi-strand wire obstacles.

Clearing a pathway 45 meters in length, one APOBS clears what it would take 27 sections of Bangalore Torpedo to clear. APOBS can be easily transported and deployed by a two-person team. This lightweight system is carried in two backpacks and a small, soft pack with a combined weight of 125 pounds and a setup time of less than 2 minutes.

APOBS can either be employed with either “Delay Mode” or “Command Mode” initiation of the tractor rocket motor. Line charge detonation occurs approximately 10 seconds after launch.

APOBS meets the Insensitive Munition (IM) safety and hazard standards defined in MIL-STD-2105 and also meets the fuze board safety requirements of MIL-STD-1316. The Forward and Aft Fuze provide safety redundancy. The system meets Hazards of Electromagnetic Radiation to Ordnance (HERO) requirements by using no electrically initiated devices. The environmentally sealed shipping and storage container and backpacks ensure a long shelf life.
