Non-Intrusive Inspection Technology (NIITEK), a Chemring Group subsidiary, has been awarded a contract to deliver spare parts for the US Army’s existing ground penetrating radar (GPR) husky mounted detection system (HMDS).

The $161m initial order is a part of the $579m indefinite-delivery/indefinite-quantity (IDIQ), under which the company will supply spares and replacement systems to replenish theatre sustainment stock.

Chemring chief executive David Price said: "The HMDS continues to contribute to the safety of US and coalition forces; and this contract will ensure operational availability of these critical systems."

The contract is also expected to provide future system requirements for the US Army Marine Corps, as well as potential foreign military sales (FMS) to customers worldwide.

Designed to support the army’s route clearance and area clearance operations, the HMDS helps in detecting the location of surface laid and buried explosive threats, including improvised explosive devices (IEDs) with pressure-activated trigger mechanisms, unexploded ordnance (UXO), landmines, and weapons caches.

HMDS features four large panels of VISOR 2500 ground penetrating radar, computer and monitoring system along with a global positioning system (GPS), which provides the operator with 2D and 3D views of objects buried under the ground.

The system was deployed in Afghanistan in early 2008 and successfully detected pressure-plate IEDs prior to their detonation in a wide range of road surfaces and soil conditions.

More than 240 systems have been ordered by the military in the US and Canada to date, of which a significant number are already in use in support of US peacekeeping missions worldwide.
