DTI Thailand Delivers CS/AH2 105mm Light Artillery Prototypes to Royal Thai Army.

The Defense Technology Institute (DTI) of Thailand has delivered two prototypes of the 105mm light howitzer CS/AH2 to the Artillery Battalion at the Artillery Center of the Royal Thai Army. The delivery, which took place at Bhumibol Camp in Lopburi Province, was officially announced by DTI on its Facebook page on April 24, 2024. These prototypes represent the culmination of a joint research and development initiative between DTI and the Artillery Center, marking a crucial step in enhancing artillery training and operational readiness of the Royal Thai Army.

The development of the CS/AH2 105mm light artillery began as part of a broader collaborative effort, initiated in September 2021 when DTI Thailand secured a contract worth 48 million baht ($1,439,712) with POLY TECHNOLOGIES, INC. from the People's Republic of China. This collaboration aims to produce a light cannon specifically tailored for export markets. Following a memorandum of understanding signed on March 15, 2023, between Thai DTI and the Artillery Center, comprehensive testing including firing tests were conducted throughout 2023 at Khao Phu Lon Artillery Shooting Range, leading to the successful delivery of these advanced units.

The design and features of the CS/AH2 prototypes incorporate elements similar to those found in established light cannons such as the BAE Systems M119 (L119) and the Nexter LG1 Mk III towed light cannon. Notably, the CS/AH2 is equipped with a sophisticated digital fire control system and satellite coordinate capabilities, as confirmed by its similarity to the display systems used in the recently serviced Nexter LG1 Mk III by the Thai military.

The M119 (known as the L119 in British service) is a lightweight, towed, 105mm howitzer used by the United States Army and Marine Corps. It is designed for rapid deployment and high mobility in various battlefield environments, making it suitable for airborne and airmobile forces. The M119 offers a maximum range of approximately 11,500 meters and supports various types of ammunition designed for multiple combat scenarios. This howitzer features a hydro-pneumatic recoil system and can be fired from a range of elevations, enhancing its versatility. Its lightweight construction allows it to be transported by helicopter or even parachuted into operational areas. The gun is capable of direct and indirect firing and is particularly valued for its accuracy and quick deployment in the field.

The Nexter LG1 Mk III towed light cannon is a modern 105mm howitzer operated by several countries, including Belgium, Canada, and Thailand. Like the M119, it is designed for rapid deployment and high mobility, but with a focus on compactness and an even lighter frame, weighing less than 1,650 kg. This makes the LG1 Mk III one of the lightest artillery pieces in its class. It boasts a maximum range exceeding 17,000 meters when firing extended-range ammunition, significantly greater than the M119. The LG1 Mk III is equipped with a sophisticated digital fire control system, allowing for greater accuracy and the ability to integrate with modern military communication networks for coordinated operations. Its operational flexibility is enhanced by its compatibility with various towing vehicles and aircraft, facilitating easy integration into existing forces.

As Thailand seeks to replace aging artillery systems, such as the 12 M425 rubber-wheeled self-propelled light cannons and 32 locally built towed light artillery M618A2 units, the introduction of the CS/AH2 comes at a critical time. The ongoing efforts of the Royal Thai Army to modernize its artillery units are supported by this development, positioning the CS/AH2 as a potential replacement for these outdated systems.
