Under the terms of the agreement, Hanwha Defense Australia will produce 30 AS9 howitzers and 15 AS10 Armored Ammunition Resupply Vehicles. These vehicles will be manufactured at the Hanwha Armoured Vehicle Centre in Geelong, Victoria, with the final deliveries scheduled for completion by 2027. The AS9 underwent extensive testing at South Korea’s Changwon Proving Ground, where its design and capabilities were validated.
The AS9 Huntsman is based on the K9 Thunder platform developed by South Korea. It features a 155mm/52-caliber main gun capable of firing standard rounds up to 40 kilometres and specialised ammunition up to 60 kilometres. The vehicle includes a semi-automated loading mechanism, enabling it to fire three rounds within 15 seconds and maintain a sustained rate of six to eight rounds per minute. Its Kongsberg fire control system is compatible with NATO-standard munitions, ensuring interoperability with allied forces.
Designed for operational versatility, the AS9 incorporates reinforced armour, anti-tank mine protection, and an advanced suspension system. Additional features include air conditioning for operation in high-temperature environments. The vehicle measures 12.4 metres in length, 3.5 metres in width, and 3.7 metres in height, with a weight of approximately 52 tonnes. It has a maximum speed exceeding 60 km/h and operates with a crew of five. For additional flexibility, it supports pintle-mounted weapons and a Remote Weapon System (RWS).
The accompanying AS10 Armored Ammunition Resupply Vehicle, built on the AS9’s chassis, is equipped with an automated loading system. This system reduces crew exposure during reloading operations, improving safety in high-risk environments. Together, the AS9 and AS10 are set to replace the M777 towed howitzers in key artillery roles, although the M777 will remain in service for air-mobile missions.
