US Army names XM1776 Mobile Tactical Cannon and orders 9 prototypes
The U.S. Army has officially designated its new wheeled 155 mm self-propelled howitzer as the XM1776 Mobile Tactical Cannon and increased its prototype order to nine systems, with an option for nine more.
Hanwha Defense USA Expands XM1776 Prototype Commitment
The updated agreement with Hanwha Defense USA expands the initial prototype commitment from six units to nine, preserving an option for an additional nine systems that keeps the potential total at 18. When the U.S. Army selected Hanwha in August 2026, the initial contract called for six prototypes delivered on an accelerated schedule with options for 12 more, valued at up to approximately $263 million. Neither the manufacturer nor the U.S. Army disclosed the financial value of the modified prototype agreement, specific delivery timelines, or the exact count of systems already handed over to military testers. The first prototype arrived earlier in the fall of 2026 and appeared at a U.S. Army event on Capitol Hill.
Hanwha Establishes Alabama Site for Domestic Production
Hanwha Defense USA is establishing an integration and test site in Opelika, Alabama, as the initial phase of domestic production for the XM1776 and other wheeled variants of the K9 system. Company leaders are meeting with more than 70 current and prospective American suppliers to build what the company terms an Artillery Industrial Base Coalition, designed to transition portions of the supply chain inside the United States. Mike Smith, Hanwha Defense USA chief operating officer and president of land systems, stated that the cannon marks the launch of the Army’s new long-range precision fires modernization effort and its partnership with HDUSA to produce the system at speed and scale.
XM1776 Offers Mobility and Range over Towed Systems
The XM1776 is built around the 52-caliber gun utilized on Hanwha’s tracked K9 platform, which is currently deployed with South Korea and roughly 10 other nations across more than 2,500 fielded units worldwide. As a self-propelled platform, the XM1776 allows crews to fire and reposition before enemy counter-battery fire arrives, offering a mobility advantage over towed systems like the M777. The longer barrel configuration also extends maximum firing range beyond that of the M777. The U.S. Army intends to field the new cannon initially to Stryker brigade combat teams, followed by mobile and infantry brigades, with an objective of having a ready version inside active units by 2031 while simultaneously running a separate competition for a tracked Mobile Tactical Cannon variant.
