IDEX 2025: Norinco’s SH16A wheeled 155 mm SPH makes its international debut

China’s SH16A wheeled 155 mm self-propelled howitzer (SPH) made its international debut at the IDEX 2025 defence exhibition, held in Abu Dhabi from 17-21 February.

The SH16A is a product of state-owned Norinco Corporation (China North Industries Group) that was first unveiled relatively recently, in November 2024, at the China International Aviation and Aerospace Exhibition in Zhuhai.

The SH16A is mounted on an 8×8 VN23 chassis, whereas the earlier SH16 was mounted on a 6×6 truck chassis.

The SH-16A’s weight, including a full ammunition load, is 36 tons. The crew consists of a driver and one or two gunners. According to the manufacturer, the new model features an enhanced hull and better mobility in difficult terrain. Its maximum speed is 110 km/h.

The vehicle is equipped with an adjustable suspension system, allowing for air transport, as well as improved protection against mines and improvised explosive devices. Its armour system, reported rated as equivalent to STANAG 4569 Level 4, provides resistance against some anti-tank weapons as well as shell splinters and small arms fire.

The SH-16A features an automatic loading system and a remotely controlled gun, enabling operation of the howitzer from outside the vehicle. The gun is capable of firing a variety of ammunition, including guided rounds, and has a declared maximum range of up to 56 km. The turret can carry up to 30 rounds.

One of the key innovations of the system is its laser ignition technology. According to the manufacturer, this ensures a more stable and synchronised ignition compared to traditional methods. The Chinese report two modes: direct ignition, where the laser directly initiates the charge; and multi-point ignition, where the laser energy is transmitted via a fibre optic system, enabling simultaneous firing of charges at multiple points.
