First Win armoured vehicle orders and deliveries
The Royal Thai Army received 29 units, as of April 2014, and placed an order for another 200 vehicles. Deftech signed a contract with Chaiseri to acquire the first batch of 20 First Win 4×4 tactical vehicles for the Malaysian Army.
The first six units, which will be manufactured by Chaiseri, are scheduled for delivery in 2016, while the remaining will be manufactured and assembled by DRB-HICOM Defence Technologies (Deftech). The vehicles will be known as AV4 in Malaysian service.
Design and features of the wheeled armoured vehicle
The V-shaped, monocoque hull of the First Win is of all-welded steel armour construction. The vehicle can be transported aboard C130 / A400M military transport aircraft, Ro-Ro ships and rail.
The armoured vehicle has a length of approximately 5.8m, width of 2.34m, height of 2.5m, and wheel base of 3.26m. The gross vehicle weight and empty weights of the vehicle are 13,000kg and 11,500kg respectively. The vehicle can carry payloads of 2,000kg and its fuel capacity is 200l.
It features a modular design and is manned by a driver and ten infantrymen. It is available in 2+1 door and 4+1 door configurations. Equipments installed in the vehicle include an air-conditioning system, a 24VDC electrical system, and an electric winch.
Armament of First Win armoured vehicle
The First Win tactical vehicle features a remotely-operated turret system, armed with 0.5-calibre machine gun or 7.62mm light machine gun.
The Malaysian variant is outfitted with a 360°-rotating manual turret system with a ballistic protection hatch and a spring-loaded pintle mount to carry 7.62mm general-purpose machine gun or 12.7mm heavy machine gun. The 76mm grenade launchers on either side of the vehicle provide additional survivability.
The armoured vehicle's cabin is armoured to the STANAG Level 2 ballistic protection, while its engine compartment is protected up to STANAG Level 1 standard.
The monocoque hull offers blast protection and survivability up to STANAG 4569 Level 3b against the explosion of an 8kg TNT mine under the vehicle, and up to STANAG 4569 Level 4a against the blast of 10kg mine under any wheel.
Engine and driveline
A Cummins ISB engine, mounted at the front, provides high mobility to the vehicle. The engine generates an output power of 300hp at 2,850rpm and a torque of 475nm at 3,100rpm, and is coupled to an Allison 2500 automatic transmission system, which has six forward and one reverse gear. Power-to-weight ratio of the vehicle is 23hp/t.
The First Win has selectable 4x4 or 4x2 drive configurations with differential lock. The 365/80 R20 tyres provide superior cross-country mobility, while the independent suspension on front and rear axles ensures better ride quality.
The vehicle features RTC60 transfer case, anti-lock braking system (ABS), automatic tyre inflation system with run-flats, R20 wheels, heavy-duty drum brakes, and mechanical parking brakes. It comes with hydraulic power assisted steering, reducing the driver's effort.
