Design and features of the wheeled armoured vehicle

First Win 4 x 4

Technical data source:

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.

First Win IFV (First Win II)

First Win IFV (First Win II)

First Win IFV or First Win II is based on the version sold to Malaysia but with further improvements. 

The disclosure of the order of 13 First Win II wheeled vehicles was announced by the Thai Army spokesman, Colonel Winthai Suvaree, to clarify to the media regarding the approval by the Thai Cabinet of the procurement of 34 VN1 8x8 IFV from NORINCO that the First Win is a MARP and is not in the same category as the VN1 which is an IFV.

Koolhiran explained the improvements made to the First Win 2 compared to the first generation of mine-resistant ambush-protected (MRAP) vehicles.

The most significant is an increase in armour protection. Ballistic protection of the hull has moved from STANAG 4569 Level 1 to 2, while mine blast protection offered by the V-shaped hull has moved from STANAG 4569 Level 2 to 3b.

This enhanced protection has been achieved without any increase in its 11t weight thanks to the use of new imported armour steel. That means there was no need for modifications to be made to the First Win 2’s Cummins ISB 300hp engine coupled to an Allison 2500 automatic transmission. Applique armour can be added to further increase hull protection.

A second major improvement on the First Win 2 is the integration of a digital backbone into the vehicle. As well as a command-and-control system, this backbone connects to an all-round thermal camera system for the driver and commander (up to 16 cameras) and a laser warning system connected to smoke grenade launchers.

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.

Protection features

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 First Win vehicles are operational with the Royal Thai Army and the Thai Ministry of Justice."

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.

Mobility of First Win

The vehicle can attain a maximum speed of 110km and a maximum cruising range of approximately 600km. It has a ground clearance of 400m, and gradient and side slopes of 60% and 40% respectively. It can climb vertical obstacles of 0.5m, cross trenches of 0.9m, and ford in up to 1m-deep waters.
