The ‘Husky’ is a unique landmine detection vehicle that is blast survivable, over-
pass capable and field reparable. This exceptional vehicle has been combat proven

Husky vehicles are no longer fitted merely with a simple metal detection system.
More sophisticated high sensitivity low metal content detectors, and alternative
sensors like Ground Penetrating Radar have now been operationalized and are
being fitted to the vehicles along with other devices such as the cyclone blower
and robotic arms.

Detection System Developments
Remote Search Head Lifting Mechanism
The height of the search heads on the current
production vehicles can only be adjusted
outside the vehicle and requires two people
to do this task. Operators are faced with a
compromise of sensitivity versus terrain ma-
noeuvrability, which needs to be determined
before embarking on a mission. The newly
developed Search Head Lifting Mechanism
allows the operator to adjust the height of
the search heads from inside the cab. Electric
actuators control the tilt and lift, and the
operator can select four heights, ranging
from 450 mm to 150 mm above the ground.
The modular design of the system facilitates
simple implementation on vehicles, and
existing vehicles can easily be upgraded.

Tire Developments
New Overpass Tire
Due to the increased mass of the vehicle and a desire to retain the overpass characteristics, a new 550 mm wide overpass tire has been
developed that allows us to achieve 12.5 psi mean ground pressure, with an increased wheel load.
Husky 450/80 R20 overpass tire footprint at 0.6 bar - 9 psi
New MDT Tire
RSD conducted tests on two different tires at the CSIR (Council for Scientific and Industrial Research) that could replace the existing MDT tires.
385/65 R22.5 radial tire footprint at 3 bar - 44 psi
Initial tests indicate that a 385/65 R22.5 radial tire inflated to 3 to 3.5 bar/ 44 to 51 psi exerts consistent increased pressure over the 3 m wide
proofing path, thereby ensuring no pressure fused mines can be missed by the MDT.
