The US Army officially designated its new mobile howitzer prototype the XM1776 during a ceremony at the Association of the United States Army (AUSA) conference in Washington, D.C. on Monday. The announcement coincided with the Army taking possession of the first prototype of the Mobile Tactical Cannon, which is developed by Hanwha Defense USA.
The XM1776 is derived from Hanwha’s K9 Mobile Howitzer and is built on a truck chassis. It features a roughly 26-foot-long barrel and is operated by a crew of three. According to the Army, the vehicle is designed to offer greater mobility and range than the current towed M777 howitzer.
Jason Pak, senior director of business development and head of land systems artillery at Hanwha, told Task & Purpose that the cannon can fire as many as nine rounds per minute. This is more than double the M777’s rate of four rounds per minute. Pak noted that the automated loader allows soldiers to operate the cannon from inside the truck cab using cameras installed in the turret. If automation fails, the system can be fired manually.
Regarding range, Task & Purpose reports the XM1776 can strike targets up to 37 miles away, compared to the M777’s 20-mile range with specific ammunition. However, Washington Examiner quotes Michael Smith, President and Chief Operating Officer of Hanwha Defense USA, stating the 58-caliber barrel can fire rounds "well beyond" 50 miles. Due to this discrepancy in reported range figures, the specific maximum distance remains unconfirmed by a single consistent source.
The development of the XM1776 is influenced by lessons from the war in Ukraine, particularly regarding the vulnerabilities of traditional artillery. Smith stated that the war highlighted deficiencies in the M777 and M109 self-propelled howitzers concerning range, survivability, and volume of fire.
"In this battle space, within 30 seconds of first fire, you’re going to have a drone on top of you," Smith said. "So the need to shoot and scoot, to get in place, fire, displace, within 90 seconds, is a must."
The Army noted that the goal for these faster-moving cannons is to increase mobility and reliability on "the modern, highly transparent battlefield" where drones and counter-battery systems make slower positions vulnerable. Smith said the XM1776 can deploy its four stabilizers within about 18 seconds. The vehicle carries 40 on-board shells and can be resupplied automatically by the K10 Ammunition Resupply System.
Lt. Gen. Francisco J. Lozano, director of the Rapid Capabilities and Critical Technologies Office, announced the designation. He stated the name XM1776 reflects "the spirit of innovation, independence, and determination that has long characterized the United States Army and the nation it serves."
The Army has ordered six prototypes under an Other Transaction Authority contract, with an option to buy 12 more. Pak explained that this contract structure allows for testing, experimentation, and modifications before full-rate production. Hanwha is setting up a test facility in Opelika, Alabama, to develop the system with the Army.
Smith said Hanwha aims to produce 48 vehicles per year, though he noted "the Army would love to see 96 per year," which would require additional investment. The Army stated that if approved for fielding, the XM1776 will replace the M777 in "select formations" rather than outright replacing it across the entire force.
The XM1776 represents a shift in US artillery strategy toward wheeled, highly mobile systems capable of rapid deployment and displacement. This change addresses the increased threat of drone surveillance and counter-battery fire observed in recent conflicts, aiming to keep artillery crews alive and operational in contested environments.
