Hanwha Aerospace has initiated the production of a wheeled variant of its K9 Thunder self-propelled howitzer, anticipating that testing will commence in early 2026. This new iteration aims to enhance mobility for users in areas with well-developed road infrastructure.
The wheeled version is derived from the latest K9A2 model, featuring a remarkable 155mm 58-caliber barrel that spans 9 meters (29.5 feet). This extended barrel design allows for a firing range that exceeds 70 kilometers (43 miles), significantly outperforming existing artillery systems. The introduction of the longest barrel yet developed for artillery systems marks a notable advancement, particularly following a previous unsuccessful attempt by the US Army to integrate a similar barrel due to issues related to barrel wear.
The development of the wheeled variant began in mid-2024, prompted by Hanwha’s loss to KNDS’ RCH 155 in the UK’s Multi-Purpose Howitzer program. Learning from this setback, Hanwha is now focusing on attracting new customers, including the US Army. As part of an initiative to modernize its aging 155mm fleet, the Army has selected Hanwha, along with four other companies, to demonstrate its self-propelled howitzers.
In response to a US Army request for information on a mobile tactical cannon, Hanwha has tailored its offerings to fit US requirements. The company is prepared to adapt its existing tracked variant and establish a comprehensive domestic supply chain to support production in the United States. “We’re absolutely committed to US jobs and capacity,” stated Jason Pak, Senior Director of Business Development for Land Systems at Hanwha Defense USA.
In addition to pledging rapid initial deliveries from Korea, Hanwha plans to shift to full production and support within the US. The company aims to include a US-specific fire control system and present options for upgrading the howitzer to more advanced versions as they become available.
