Boom Box: APOBS Mine-Breaching Line Charge Shifts to Chemring

APOBS

The MK7 MOD 2 Anti-Personnel Obstacle Breaching System (APOBS) is used to clear mines or wire obstacles, and create a safe footpath for troops. APOBS can be carried by 2 people, takes 30 to 120 seconds to be set up, and fires a rocket from a 25-meter standoff position, sending a line charge with fragmentation grenades over the minefields or wire obstacles. The grenades clear the mines, and sever the wires. Developed by the US Army Armaments Engineering and Technology Center in Picatinny Arsenal, NJ, APOBS won a US Army top military inventions of the year award in 2004. It replaces the Bangalore Torpedo, which was heavier, took longer to set up, and required 4 times the number of people to carry.

In 2006, small business qualifier Ensign-Bickford Aerospace & Defense Co. in Simsbury, CT received a maximum $150.8 million, 5-year contract for up to 3,000 units. In 2011, however, the Army/USMC contract shifted to Chemring Ordnance, Inc. in Perry, FL…

Rapid Fire August 28, 2012: International Armament Sales Data

• The Congressional Research Service updated their report [PDF] on international conventional weapon sales with 2011 data. Agreements for new sales from the US to developing nations boomed above $56B or a close to 80% market share, leaving #2 Russia far behind. The mega deal with Saudi Arabia was the biggest contributor to that surge in demand for American armament. Deliveries during 2011 were less lopsided but the US still led with close to 38% of the total in value.

• The RAND Corporation looked into the reasons behind high cost increases in the Army Excalibur artillery round and the Navy’s Enterprise Resource Planning (ERP) programs. In the case of Excalibur, smaller ordered quantities was the primary driver for its Nunn-McCurdy cost breach. Looking for a deeper root cause, that reduction was triggered by the increased precision of modern artillery. Meanwhile the Navy ERP started with an optimistic baseline, as happens very often with software implementation projects.
