Terrex ICV Design
As with a number of other recent wheeled armoured vehicles, the Terrex is of modular design with various levels of armour protection and weapon systems being marketed up to a gross vehicle weight of 24,000 kg. Along with its size, the Terrex is air portable by C-130s or other similar cargo aircraft.
The Terrex's layout is conventional: the driver sits front left and the power pack is to the right. This leaves the rest of the vehicle clear for the troop compartment, which is provided with a power-operated ramp and roof hatches.
Various weapon systems can be fitted on the roof, including a remote weapon station armed with a 40mm automatic grenade launcher and a 7.62mm coaxial machine gun or a complete stabilized turret armed with a 25mm M242 Bushmaster cannon and 7.62mm coaxial machine gun. Additional 7.62mm machine guns can be mounted over the rear troop compartment. In addition, the vehicle can be configured to carry varying combat payloads - from turreted weapon stations (including 105 mm tank guns) to rocket launchers. The modular top deck allows for quick configuration change.
The Terrex AV-81 uses a patented independent double wishbone suspension, which greatly improves ground mobility and ride comfort over the roughest terrain. The use of automatic traction control and the capacity for large footprint off-road tires enables it to traverse at unprecedented speeds in soft ground conditions.
The vehicle has a double hull with an external V-hull that improves mine blast survivability. Add-on armour provides further protection for troops. It is also capable of providing full Nuclear, Biological and Chemical protection in extreme operational conditions.
Standard equipment includes powered steering on the front four wheels, central tyre-pressure inflation system, anti-lock braking system and nuclear, biological and chemical defensive system, but there are numerous other options.
In its baseline configuration, the AV-81 Terrex is fully amphibious: two water jets mounted on either side at the back of the hull propel the vehicle through water at 10 km/h.
