The U.S. Army is ordering nine prototype wheeled XM1776 Mobile Tactical Cannon systems, Hanwha Defense USA, or HDUSA, said after the company and the service formally named the platform. The XM1776 is a U.S. variant of Hanwha’s K9 Mobile Howitzer.
Army and HDUSA representatives held the naming ceremony Monday at the company’s exhibit at AUSA 2026, the Association of the U.S. Army’s annual meeting and exposition. The order includes an option for nine further units.
What Is the XM1776 Mobile Tactical Cannon?
HDUSA describes the XM1776 as a 155mm artillery system that can be fielded quickly to support Army modernization goals. The Hanwha Aerospace subsidiary entered the K9 in the Army’s Mobile Tactical Cannon competition. In August, it received a $100 million other transaction agreement with a $263 million ceiling to fast-track six prototypes. That award included an option for 12 more systems, which would replace M777 towed howitzers in select formations if approved for use. More than 2,500 K9 systems are in service worldwide, including in Australia, Finland and Norway.
What Milestone Does Hanwha See in the Cannon’s Launch?
Mike Smith, HDUSA’s chief operating officer and president of land systems, said the platform marks the start of a new Army push to modernize long-range precision fires.
“The XM1776 Mobile Tactical Cannon represents the launch of the U.S. Army’s new long-range precision fires modernization effort and its powerful partnership with HDUSA to produce this system at speed and scale,” Smith said.
He added that Hanwha intends to speed up domestic output and grow the nation’s artillery manufacturing base as the United States marks its 250th anniversary.
How Is Hanwha Building a U.S. Artillery Supply Chain?
The company is setting up its Phase I location in Opelika, Alabama, to integrate and test the XM1776 and the wider K9 family. To speed localization, HDUSA leaders plan to meet with more than 70 current and prospective vendors to form an Artillery Industrial Base Coalition. Hanwha said its global defense presence can strengthen U.S. readiness and improve interoperability with allied K9 operators as it works with the Department of War to build high-volume capacity.
The effort follows HDUSA’s announcement of a planned $2.2 billion munitions campus at Pine Bluff Arsenal in Arkansas. The campus would produce 155mm propellant charges and base bleed units and create about 400 jobs over seven years.
