The SH-1 self-propelled howitzer was developed by NORINCO for the export market. Development of this artillery system commenced in 2002. It was modeled after a French CASEAR. This Chinese artillery system was first revealed in 2007. Details of this artillery system were released at the same time as were details of the smaller SH-2 122 mm truck-mounted howitzer. Pakistan acquired a total of 90 SH-1 truck-mounted howitzers. Deliveries were completed between 2012 and 2013. This artillery system is also in service with Myanmar. In 2022 the SH-1 was delivered to Cambodia. Chinese army does not use this artillery system.

   The SH-1 self-propelled artillery system is fitted with an ordnance of an AH-2 155 mm/L52 howitzer. It is compatible with all standard 155 mm NATO ammunition, as well as ammunition developed by NORINCO. So this howitzer can use a wide variety of different ammunition. The SH-1 is capable of direct and indirect firing. Claimed maximum range of fire is 53 km which was achieved with a rocket assisted V-LAP projectile using charge zone 10. In addition this artillery system can use Chinese precision-guided munitions, based on the Russian Krasnopol laser-guided projectile technology. China obtained this technology and production license for the Krasnopol guided projectiles in the late 1990s and successfully developed its own variants. Its export designation is the GP1. These laser-guided projectiles have a maximum range of 20 km.

   Ammunition box of the SH-1 artillery system houses 25 rounds of seven different types and their modular charges.

   Before firing a large spade is lowered to the ground. It provides more stable firing platform. Maximum rate of fire is up to 4-6 rounds per minute. Conversion time form firing to travelling order is only 1 minute. So this howitzer can briefly fire a couple of shells and leave its firing position before hostile forces open a counter-battery fire.

   The SH-1 is fitted with a computerized fire control system, navigation, positioning and targeting systems. Vehicle receives target information from artillery command vehicle.

   Secondary armament consists of a 12.7 mm machine gun, mounted on top of the roof. This weapon is used for self-defense.

   Vehicle has a crew of five. An armored cab provides protection against small arms fire and artillery shell splinters.

   The SH-1 artillery system uses a Wanshan WS5252 6x6 truck chassis. It is powered by a 330 hp diesel engine. This artillery system is highly mobile and can self-deploy over long distances. It can be airlifted by most medium transport aircraft. It is light enough to be airlifted by a Y-9 or similar military transport aircraft, making it a more flexible option for a China's growing rapid reaction units.

   A complete SH-1 regiment includes 24 truck-mounted howitzers, 4 battery command post vehicles, one battalion command post vehicle, one meteorological radar, 4 wheeled reconnaissance vehicles with 6x6 configuration and one artillery locating radar.
