Elbit Systems of America and Anduril Industries have announced a strategic partnership to offer the SIGMA Mobile Tactical Cannon for the US Army’s Self-Propelled Howitzer Modernization program.
The effort brings together Elbit America’s experience in military vehicle integration and manufacturing with Anduril’s expertise in battlefield software, communications, and autonomous technologies.
The announcement marks a significant step in the competition to provide the US Army with a next-generation self-propelled artillery system. The companies aim to deliver a fully domestic solution that supports military readiness while strengthening the American defense industrial base.
SIGMA Cannon’s Combat-Ready Design
The SIGMA Mobile Tactical Cannon is a wheeled self-propelled howitzer designed to provide long-range fire support while maintaining high mobility. Unlike traditional tracked artillery systems, SIGMA uses a 10×10 wheeled platform that allows it to move quickly across roads and challenging terrain while keeping pace with maneuvering forces.
Elbit America said the system is already combat-proven and offers the reliability needed for modern military operations. The company also highlighted that SIGMA is built in the US using a domestic supply chain, reducing dependence on foreign suppliers and supporting long-term sustainment.
Under the teaming agreement, Anduril will help integrate the system with existing US Army command and fire control networks. The company plans to use its expertise in command, control, communications, computers, cyber, intelligence, surveillance, and reconnaissance (C5ISR) technologies.
Anduril also intends to incorporate its Lattice software platform into future versions of the SIGMA system. Lattice is designed to connect sensors, systems, and operators on the battlefield, helping commanders make faster decisions and enabling advanced autonomous functions.

Luke Savoie, President and CEO of Elbit America, said the partnership will help reduce integration risks and speed up deployment if the system is selected by the Army. He emphasized that SIGMA provides a modern and dependable artillery capability built entirely in the US.
Michael Roder, Managing Director at Anduril, said the company will contribute software, edge computing, and autonomy technologies to create a connected artillery platform. He added that the system is being designed to work seamlessly with current Army command-and-control architectures.
300 American Suppliers Involved
The broader Team SIGMA effort also includes Oshkosh Defense, which supplies the vehicle chassis. Oshkosh is responsible for the system’s 10×10 platform, providing mobility and protection for the crew operating the cannon.
According to the companies, more than 300 American suppliers contribute to the program. This supplier network supports engineering, manufacturing, and logistics while helping ensure production capacity can meet future military requirements.
One of SIGMA’s key features is its ability to fire in a full 360-degree arc. Traditional artillery systems often require repositioning to engage targets in different directions, but SIGMA is designed to reduce those limitations and improve responsiveness on the battlefield.
The system can carry up to 40 rounds of ammunition and fire up to 8 rounds per minute. This combination of ammunition capacity and firing speed is intended to support sustained operations while reducing the need for frequent resupply.

Crew Protection Meets Mobility
Crew protection is another major focus of the design. The cannon operates from an armored platform that helps protect soldiers while allowing rapid movement before and after firing, an important factor in avoiding enemy counter-battery attacks.
The Army’s modernization effort comes at a time when military planners around the world are placing renewed emphasis on long-range precision fires. Recent conflicts have demonstrated the importance of mobile artillery systems that can quickly relocate, stay connected to battlefield networks, and maintain a high operational tempo.
For the US, the program is about more than replacing older artillery systems. It is also an opportunity to strengthen domestic manufacturing, improve supply chain resilience, and introduce digital technologies that support future military operations.
