Terrex is developed by ST Engineering of Singapore and Timoney Technology of Ireland, and produced by ST Engineering Land Systems for the Singapore Army
Singapore’s defense industry is making miraculous progress. The defense products developed by this country are comparable to the military powers, among them the Terrex AV81 armoured fighting vehicle.
Terrex is developed by ST Engineering of Singapore and Timoney Technology of Ireland, and produced by ST Engineering Land Systems for the Singapore Army as well as by Turkish auto-maker Otokar (manufacturing it under a license) as the Yavuz (AV-82) for the Turkish military.
Design work began in the late 1990s. Vehicle underwent initial trials in Ireland and United Kingdom and was shipped to Singapore for evaluation in the year 2000. Production commenced in 2006. The Singapore Armed Forces are operating about 435 of these vehicles. It was exported to Ghana with 19 units. Despite its size, the Terrex is air-portable by C-130s or other similar cargo aircraft.
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 turret-based weapon stations to rocket launchers (including 105 mm tank guns). The modular top deck allows for quick configuration changes to be carried out.
AV-81 is equipped with a Caterpillar C9 diesel engine, with 400 horsepower, for a maximum speed of up to 110 km / h, a range of 800 km. The vehicle uses a patented independent double wishbone suspension, which greatly improves ground mobility and ride comfort over rough terrain. The use of automatic traction control and the capacity for large footprint off-road tires enables it to travel at unprecedented speeds in soft ground conditions.
