China offers its new SH16A 155mm self-propelled howitzer to Middle Eastern countries at IDEX 2025.

At IDEX 2025, the Chinese state-owned company Norinco offered the new SH16A 155mm self-propelled howitzer (SPH) to the Middle East market for the first time. The system is mounted on an 8×8 wheeled chassis and is designed for mobility, protection, and precision firepower. Norinco has stated that the SH16A is fully developed and ready for production upon receiving orders.

Norinco has developed several wheeled artillery platforms in recent years, transitioning from the 152mm caliber used in Russian-derived systems to the NATO-standard 155mm caliber. The SH16A follows previous models such as the SH1 and SH15 and was first unveiled at the 15th China Air Show in 2024. The system is based on the VN-22 8×8 chassis and incorporates modifications in load capacity, protection, and modularity. It features a remote-controlled, unmanned turret and an updated fire control system.

The SH16A is equipped with a 155mm/52-caliber gun capable of firing multiple types of ammunition, including conventional shells, laser-guided projectiles, and top-attack munitions. Its maximum range depends on the ammunition type, reaching up to 56 kilometers with bottom-bleed rocket-assisted rounds. The turret, which weighs 14 tons, is designed to be compatible with different chassis types, including both tracked and wheeled platforms. It includes a magazine-based autoloader with a 30-round capacity, allowing for rapid reloading by swapping magazines. The fire control system automates gun adjustment, fuse setting, and projectile loading.

The VN-22 chassis has a carrying capacity exceeding 15 tons, compared to the seven or eight tons of previous models, enabling the integration of additional armor and weapon systems. The vehicle has a top speed of 110 km/h and features an adjustable suspension system that enhances mobility and mine protection. A central tire inflation system is included for terrain adaptation, and the vehicle supports in-situ turning for improved maneuverability. Armor protection is rated at STANAG 4569 Level 4, providing resistance to 14.5mm armor-piercing rounds from all directions. The chassis also includes a V-shaped hull to improve mine resistance and built-in anti-drone capabilities.

The SH16A includes a laser ignition system, replacing traditional primer-based ignition. It operates in two modes: direct ignition, where the laser directly ignites the charge, and multi-point network ignition, where laser energy is transmitted via an optical fiber system to ignite multiple points simultaneously. The vehicle deploys stabilizers before firing to provide a stable firing platform. Defensive systems include electrically operated smoke grenade launchers and an optional remote weapon station.

Several Middle Eastern countries have acquired or are considering acquiring Chinese artillery systems. Saudi Arabia procured PLZ-45 self-propelled howitzers, with initial deliveries beginning in 2008. The United Arab Emirates confirmed the acquisition of six Norinco AH4 155mm towed howitzers in 2019. Egypt has explored options to diversify its military suppliers and has reportedly considered Chinese artillery systems. The decisions to purchase these systems are influenced by factors such as cost, availability, fewer export restrictions compared to Western suppliers, and diversification of defense procurement. China has also engaged in technology transfers and joint production agreements, which have been factors for countries seeking to develop their domestic defense industries.
