(click to read article)

General Dynamics Land Systems in Warren, MI received a $14.35 million firm-fixed-price, indefinite-delivery/ indefinite-quantity contract with a maximum ordering quantity of 150 Mine Roller Systems and associated manuals, spares and Interface Kits (about $95,000 per MRS). Work will be performed in Lima, OH and is expected to be complete in February 2007. DefenseLINK adds that “This contract is a sole source award to General Dynamics Land Systems as they are the sole manufacturer of the Mine Roller System.” The Marine Corps Systems Command in Quantico, VA issued the contract (M67854-06-D-5172).

A General Dynamics release notes that “The MRS is a countermine system that is mounted on wheeled vehicles to reduce the impact of pressure-activated explosive devices. The MRS detects and neutralizes mines and improvised explosive devices before the host vehicle passes over the explosive device. The MRS will be integrated on Marine Corps Light Armored Vehicles (LAVs), Medium Tactical Vehicle Replacements [DID: USMC medium trucks], Joint Explosive Ordnance Disposal Rapid Response Vehicles [DID: Cougar family], and High Mobility Multi-Wheeled Vehicles (HMMWVs).”

A recent DefendAmerica.MIL article noted that 2nd Battalion, 503rd Parachute Infantry Regiment mechanics serving in Afghanistan have created a similar system from scavenged parts, and verified its effectiveness. As an additional safety measure, a cable to the Humvee frame becomes taut if their roller triggers an explosion, in order to keep the roller from flipping back and crushing the drivers inside the vehicle.
