The Terrex Armoured vehicle personnel carrier was developed as a private venture by Singapore Technologies Kinetics in close association with Timoney High Mobility Vehicles of Ireland. The first prototype of the Terrex AV81 APC was completed in the facilities of Timoney Technology of Ireland, which is now partly owned by Singapore Technologies Kinetics. This was first shown in the UK late in 2001. In late 2003 the first of two preproduction models of the Terrex APC was completed and the first of these made its first public appearance during the IDEF 2003 exhibition held in Ankara. On 31st May 2011, the Singapore Armed Forces' (SAF) first Motorised Infantry Battalion was declared fully operational. It was a groundbreaking milestone for our Army's continuous push to enhance our fighting capability. Held at the Murai Urban Training Facility (MUTF), the soldiers of the 2nd Battalion Singapore Infantry Regiment (2 SIR) displayed to all present their enhanced fighting capabilities integrating the Terrex Infantry Carrier Vehicle (ICV) into their operations.
- Terrex Personnel carrier: Designed to provide rapid mobility with protection for up to twelve soldiers, including the driver. - Terrex Command Post: Designed for command and control functions within the battalion and squadron headquarters. - Terrex Recovery: Equipped with a 20 tonne crane, mounted at the rear top of the hull, 15 tonne recovery winch and onboard generator. - Terrex Mortar carrier: equipped with 81 mm or 120 mm mortar
The TERREX can be fitted with a remote controlled weapon station armed with weapons up to 30 mm in calibre. The TERREX can be also armed with 40 mm automatic grenade launcher weapon station, which includes a coaxial 7.62 mm machine gun and smoke grenade launchers. The turret can be also replaced by a ring mount 12.7 mm machine gun. The Terrex has a modular top deck and its configuration can be changed from anti-tank missile carrier to a 105-mm fire support vehicle.
The hull of the Terrex is of all welded steel armour construction to which an additional layer of passive armour can be added for a higher level of protection. The floor of the Terrex is of a V shape to help deflect the blast of anti-tank mines. It has spaced armour in the floor and other parts of the hull for increased battlefield survivability. The all-round ballistic protection provided by the baseline hull armour provides 7.62x51 mm NATO bullet protection. Ceramic-composite add-on armour could be applied as required to the hull faces, starting 800 mm above the ground and weighting about 800 kg to provide additional protection against STANAG Level 2 to Level 4 threats.
Power pack of the Terrex consists of a Caterpillar C9 four-stroke turbocharged diesel engine developing 400 hp, coupled to an Allison MD4560P fully automatic transmission. The air intake and outlet louvers are in the roof with the exhaust outlet on the right side of the hull. This power pack gives a maximum road speed of 120 km/h. The Terrex is equipped with an independent suspension system, greatly improving ground mobility and ride comfort over the roughest terrain. The use of large footprint off-road tyres enables the Terrex to traverse soft ground with ease. Mobility is further enhanced by a built-in Central Tyre Inflation System (CTIS), allowing automated inflation and deflation of tyres to suit different terrain while on the move. The all wheel Anti-lock Braking System (ABS) improves safety for highway operations and the Traction Control System (TCS) provides better performance over rough terrain.
The TERREX is also fitted with collective NBC filtration and air conditioning system. To minimise its thermal signature, the engine exhaust is channelled downwards from the hull over head the gap between the first and second road wheels on the right side, thereby minimising the thermal bloom. 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 options. In its baseline configuration, the Terrex is fully amphibious: two water jets mounted one either side at the back of the hull propel the vehicle through water at 10km/h.
