China develops new 155mm self-propelled howitzer based on VN-22 8x8 armored vehicle.

Based on information found online, China is preparing to showcase at least three new variants of the VN-22 8x8 armored vehicle at the Zhuhai Airshow 2024. These variants include a 6x6 model equipped with a laser system for counter-drone operations, along with two 8x8 self-propelled howitzers. One of the howitzers is reported to be armed with a 125mm gun, while the other, possibly named SH-16A, features a modular turret designed for a 155mm wheeled self-propelled howitzer, which appears to be based on the SH-16 model, as it includes the same single equilibrator seen on that system.

The integration of various weapon systems for these new VN-22 variants demonstrates China's ongoing development of modular and adaptable military platforms, as they allow for rapid reconfiguration, enabling these vehicles to fulfill diverse roles such as troop transport, reconnaissance, anti-tank, and air defense. This flexibility improves operational efficiency and logistics by minimizing the need for specialized vehicles. Additionally, modularity simplifies maintenance and upgrades since weapon systems can be swapped out without extensive vehicle modifications, ensuring that these platforms can evolve to meet emerging threats.

Examples include the Turkish FNSS Pars Alpha 8x8, which accommodates different turrets and missile systems, and the Otokar Arma in both 6x6 and 8x8 versions, which can integrate anti-tank missiles and remote-controlled turrets. The Boxer 8x8, used by several nations, utilizes over 20 mission modules for roles such as infantry fighting vehicle (IFV), command vehicle, or ambulance. Other platforms like the Czech Pandur II 8x8, Swiss Piranha, and China’s Mengshi 6x6 are similarly modular, supporting various operational needs. The VN-22 from Norinco is noted for rapid deployment capabilities, while the U.S. Stryker and LAV (Light Armored Vehicle) platforms are modular enough to handle tasks ranging from anti-aircraft systems to medical evacuation.

The VN-22 was introduced in 2021 by the Norinco Group as a 6x6 wheeled armored fighting vehicle (AFV), aimed at export markets. It offers modular configurations that allow different weapon systems to be mounted depending on the needs of the customer. The vehicle operates with a crew of three and can carry up to eight infantry soldiers. It is equipped with a remotely operated turret that includes a 30mm autocannon, two HJ-12 anti-tank guided missiles, and other secondary armaments. Both the commander and gunner have independent panoramic sights and thermal imaging capabilities.

In terms of protection, the VN-22 complies with STANAG 4569 Level 4 standards, which means it is capable of withstanding 14.5mm armor-piercing rounds from all directions. The vehicle's V-shaped hull is designed to provide enhanced protection against landmines and improvised explosive devices (IEDs). It also includes the GL6 active protection system (APS), which is intended to counter incoming anti-tank missiles. The VN-22 features an adjustable suspension system to allow for mobility across various types of terrain.

Several versions of the VN-22 exist, including the VN22B, which is equipped with a 105mm cannon that is compatible with NATO-standard ammunition. Other versions include an armored recovery vehicle and an armored ambulance. The VN-22 has been exported to countries such as Iraq, Ivory Coast, and Senegal. Iraq has made modifications to the VN-22, including replacing the turret with a manually operated machine gun system, which reflects different operational needs and localized production arrangements.

The SH-16, which may be the basis for the 155mm howitzer-equipped VN-22 variant which could be named SH-16A, is a 6x6 wheeled self-propelled howitzer. It is designed to offer greater strategic mobility while maintaining similar ballistic performance to its tracked counterparts. The SH-16 is mounted on a wheeled off-road chassis and weighs 32 tons. Its turret, which weighs 14 tons, is equipped with a 52-caliber 155mm howitzer. The system requires a two-person crew, consisting of a driver and a gunner.

The SH-16's fire control system automates key processes, including gun adjustment, fuse binding, projectile loading, and propellant handling, minimizing the need for manual input. This automation is intended to streamline operations and improve performance in combat situations. The SH-16's modular design allows it to be mounted on different types of platforms, such as tracked, wheeled, and truck-based chassis, which may reduce development time and procurement costs.

The SH-16 incorporates advanced technologies, including laser ignition, modular charges, automatic loading, and intelligent control systems. It is made up of several systems, including a firepower system, task management and control system, chassis system, and auxiliary systems. The SH-16 also features an air-pressure-type equilibrator, recuperators, recoil cylinders, and a rear door for loading modular propellant charges. These features support the system's mobility and operational capacity in various environments.
