The US Army has ordered nine prototype XM1776 Mobile Tactical Cannon systems, with an option for nine more, as Hanwha Defense USA looks to expand American artillery production.
Hanwha Defense USA (HDUSA) unveiled the XM1776 at the Association of the US Army’s 2026 Annual Meeting and Exposition in Washington, DC, on October 12. The naming ceremony introduced the American designation for Hanwha’s K9 Mobile Howitzer, a wheeled artillery system based on the South Korean defense manufacturer’s established K9 artillery technology.
The company said the Army has ordered nine prototypes and retains the option to acquire an additional nine systems. The announcement follows an earlier prototyping agreement and establishes a larger group of vehicles for evaluation.
The XM1776 is intended to support the Army’s modernization objectives by combining 155 mm artillery firepower with the mobility of a wheeled platform. Unlike towed artillery, which requires a separate vehicle to move the weapon, a self-propelled howitzer integrates its gun and mobility system into a single vehicle. This can give artillery units greater flexibility when moving between firing positions.
A new approach to mobile artillery
The XM1776 is based on Hanwha’s K9 Mobile Howitzer, adapting technology from the company’s K9 family of tracked self-propelled howitzers into a wheeled configuration. The US designation reflects the system’s adaptation for the American Army, though the prototype still needs to be evaluated against US military requirements.
Wheeled artillery can offer advantages in road mobility and operational flexibility, particularly when units need to reposition quickly alongside maneuver forces. Self-propelled systems can also reduce dependence on separate towing vehicles, potentially simplifying movement between firing locations.
A new name for America’s new artillery.

In today's naming ceremony, CEO Michael Coulter, COO Mike Smith, and @USArmy leaders unveiled the new designation for our K9 Mobile Howitzer: XM1776.

These capabilities matter in battlefields where drones, surveillance systems, and counter-battery weapons can help opposing forces locate artillery positions. The ability to move after firing can reduce the time a gun remains exposed to retaliation. However, the Army must test the XM1776 to establish its performance, reliability, and suitability for operational service.
The system remains a prototype effort, rather than an operational weapon approved for full-scale production. The latest announcement does not establish a production timeline or confirm how many systems the Army might eventually acquire.
Hanwha plans to build US artillery capacity
Alongside the unveiling, Hanwha Defense USA outlined plans to expand the domestic industrial infrastructure supporting the program. The company is establishing a Phase I site in Opelika, Alabama, which will serve as a US integration and testing facility for the XM1776 and other systems in Hanwha’s K9 Mobile Howitzer family.
HDUSA also plans to meet with more than 70 existing and prospective suppliers to develop an Artillery Industrial Base Coalition. The initiative is intended to accelerate supply-chain localization and expand American participation in artillery production.
“The XM-1776 Mobile Tactical Cannon represents the launch of the U.S. Army’s new long-range precision fires modernization effort,” Mike Smith, HDUSA’s COO and president of Land Systems, said in the announcement.
Hanwha is drawing on the international production experience of its K9 artillery family. The company says it has fielded more than 2,500 K9 howitzers worldwide. That existing industrial footprint could provide a foundation for expanding production and supporting cooperation with allied operators, although the extent of shared components and sustainment arrangements for the American variant remains to be established.
The effort comes as the US seeks to strengthen its defense industrial base and improve the capacity to produce and sustain artillery systems. A domestic integration and testing facility, along with a broader supplier network, could support the program if the Army decides to move beyond prototyping.
