The US Army has advanced its extended-range artillery modernization initiative by selecting Hanwha Defense USA to support the integration of a 58-caliber cannon onto the K9 self-propelled howitzer platform. The work is being conducted under a CRADA framework and reflects renewed efforts to enhance long-range precision fires after the ERCA program was discontinued due to technical hurdles.
Hanwha recently confirmed it has offered the Army a wheeled K9 artillery variant equipped with a 58-caliber gun, building on the design of its 52-caliber K9A2 system. This mobile, truck-independent solution is one of five platforms under evaluation as the Army seeks a replacement approach for the cancelled ERCA capability.
Under the agreement, the Army’s Combat Capabilities Development Command Armaments Center will integrate a US-developed 58-caliber barrel into Hanwha’s K9 vehicle lineup. The longer barrel is expected to significantly extend firing range, with program goals targeting distances of up to 70 kilometers, more than double the reach of current self-propelled howitzers.
Hanwha is part of a competitive field that includes BAE Systems, Rheinmetall, Elbit Systems, and General Dynamics, each offering different artillery solutions. In parallel, Hanwha has highlighted the K9A2’s compatibility with the K10 resupply vehicle, which enhances sustained fire capability. The company has also emphasized its willingness to localize production and tailor both wheeled and tracked variants to meet US Army operational and industrial requirements.
