VT-5

The VT-5 is a lightweight main battle tank (MBT) introduced by China Northern Industries Group Corporation (CNGC, or NORINCO) for the export market. A similar design of unknown designation has also been fielded by the PLA Ground Force.

Background

Photos of an unidentified lightweight tank began to emerge in early 2014 on the Chinese Internet and social media. By 2017, it appeared that the tank had already entered operational service with the PLA Group Force. A lightweight MBT designated VT-5 was unveiled during the 2016 China International Aviation and Aerospace Exhibition (Zhuhai Air Show) and subsequently at the 2017 NORINCO Armour Day. The version in service with the PLA Ground Force may differ slightly to the VT-5 in hull design.

With a combat weight of 33 t, the VT-5 is designed to operate in areas unsuitable for heavy MBTs, such as highlands, hilly areas, water networks, paddy fields, etc. Its lightweight also makes the tank suitable for rapid deployment to the theatre by airlift or railway. The tank is armed with an indigenous 105 mm rifled gun with autoloader, and advanced digital fire-control comparable to that of the ZTZ-99A and MBT-3000/VT-4.

Design

The VT-5 has a conventional layout, with the driving compartment located at the front, the turret and crew compartment in the middle, and the engine compartment in the rear. The tank is operated by a three-man crew. The driver is seated left in the hull and forward of the turret. The tank commander sits on the right side of the main gun, and is also responsible for operating the 12.7-mm anti-aircraft machine gun (AAMG) mounted on his hatch cupola. The gunner sits on the left side of the main gun.

The drivetrain consists of six rubber-tyred road wheels, three return rollers, and a sprocket at the rear on each side. The tracks and wheels are protected by six panels of thick rubber side skirts. External storage for fuel and equipment are provided by encased compartments on the funders, which have been blended into the upper hull. Two headlights are located on the front of the hull.

Protection

The hull and turret are protected by composite armour plating. The frontal arc of the turret is fitted with arrow-shaped spaced armour modules. The rear half of the turret is surrounded by storage racks, which not only offer extra places for the crew to store their equipment but also provide additional protections against HEAT projectiles. Wheels and tracks are protected by rubber hull skirts. Additional protection is provided by the FY series ERA modules, which is said to be capable of defeating the new-generation tandem-warhead anti-tank guided missiles.

The crew compartment is fitted with a collective over-pressure NBC protection system and automatic fire-supressing system. A laser warning receiver (LWR) is mounted on the roof of the turret. There is a 6-barrelled smoke grenade launcher on either side of the turret, under the storage racks near the rear of the turret. Additional smoke can be generated by injecting diesel fuel in to the engine’s exhaust.

Armament

The main armament is a dual-way stabilised Chinese indigenous 105 mm rifled gun, which has been developed from the British Royal Ordnance L7 technology. The gun is fitted with a fume extractor and thermal sleeve, and is fed by an autoloader. Ammunitions include armour piercing fin stabilised discarding sabot (APFSDS), high explosive anti-tank (HEAT), and high explosive fragmentation (HE-FRAG), with 38 rounds carried (18 inside the autoloader and 20 inside the crew compartment).

The 105-mm gun is also capable of firing the Chinese gun-launched, laser beam-riding anti-tank guided missile (ATGM), which was derived from the Russian 9K116 Bastion (NATO codename: AT-10 ‘Stabber’). The missile has a maximum range of 5,200 m and an armour penetration capability of 700 mm. As well as ground targets, the missile is said to be also capable of engaging slow-flying helicopters.

Auxiliary weapons include one 7.62-mm coaxial machine gun, and a 12.7-mm/50-calibre anti-aircraft machine gun (AAMG) mounted on the commander’s hatch cupola. The tank has the option to be fitted with a remotely-operated AAMG and a 35-mm automatic grenade launcher for urban operations.

Fire-Control and Observation

The fire-control system of the VT-5 is said to be comparable to that of the heavier ZTZ-99A and MBT-3000/VT-4. Fire accuracy is attained by the dual-way stabilisation and ballistic computer with laser rangefinder and night vision inputs.

The driver is equipped with three observation periscopes, and the central periscope can be replaced by an image intensifying periscope for night vision. The gunner has a roof-mounted, dual-axis stabilised viewer incorporating a day channel, a thermal imaging system (TIS) night vision, and a laser rangefinder. The night vision employs the cooled detector thermal imaging system (TIS).

The commander’s station is equipped with six periscopes to provide all round 360° view. A commander panoramic viewer is mounted on the turret roof in front of the commander’s hatch copula, providing an independent, dual-axis stabilised, day/night vision with a 360° view, incorporated with a laser rangefinder. This arrangement allows the commander to search and engage targets directly, enabling the ‘hunter-killer’ capability.

Propulsion

The VT-5 is equipped with an indigenous 150 series liquid-cooled, turbo-charged, 8-cylinder diesel engine, producing a maximum output of 883 hp (650 kW). To improve its mobility performance, the tank is also fitted with a hydropneumatic active suspension, which can be adjusted while travelling to deal with uneven terrain in mountainous regions. The tank can attain a maximum speed of 70 km/h on road.
