- Elbit America said its SIGMA self-propelled wheeled howitzer will be on display at AUSA Global Force 2026 as its fielded offering for the U.S. Army’s Self-Propelled Howitzer Modernization program
- The company said SIGMA is built in South Carolina on a 10x10 platform, can fire all U.S. Army 155mm munitions, and is designed to shoot and move in under 60 seconds
Elbit Systems of America said its SIGMA self-propelled wheeled howitzer will be on display at the AUSA Global Force Symposium and Exhibition in Huntsville, Alabama, from March 24 to 26.
The company said SIGMA is its fielded offering for the Army’s Self-Propelled Howitzer Modernization program and will appear in Oshkosh Defense’s booth 411 at the Von Braun Center.
The display matters because the Army is looking for artillery systems that can move faster, fire quickly, and survive in more contested environments. SIGMA is being presented as a wheeled self-propelled howitzer built in the United States, with a focus on rapid maneuver, fast firing, and compatibility with the Army’s 155mm ammunition inventory.
Built in Charleston, South Carolina, SIGMA is described by Elbit America as the only self-propelled wheeled howitzer manufactured in the U.S. The company said the system uses a 10×10 platform designed to move with brigade combat teams across complex terrain and to “shoot and scoot in less than 60 seconds.”
“Shoot and scoot” refers to an artillery system’s ability to fire and then reposition quickly before enemy counterbattery fire can target its location. For modern artillery forces, that kind of mobility is closely tied to survivability, especially when opposing forces can detect firing positions faster than in past wars.
Elbit America said SIGMA delivers 360-degree firing and uses an automated 155mm turret. The company also said it is the only self-propelled wheeled cannon that can fire all variations of 155mm munitions in the U.S. Army arsenal. In the field, the system carries a 40-round onboard magazine and can fire eight rounds per minute while keeping its three-person crew inside an armored cab.
Those details place SIGMA in a growing class of mobile artillery systems designed to combine the firepower of a large-caliber gun with the speed of a wheeled chassis. A wheeled self-propelled howitzer is not the same as a towed gun, which must be emplaced and moved by another vehicle, and it is also distinct from a tracked howitzer, which usually offers different mobility and sustainment tradeoffs. Wheeled systems are often pitched as faster on roads, easier to sustain, and better suited to rapid movement over long distances, while still giving ground forces responsive indirect fire.
The automated turret is also a notable part of the system’s design. Automation can reduce crew workload and help speed up loading and firing sequences. In SIGMA’s case, Elbit America is pairing that turret with a protected cab and a relatively small three-person crew, a configuration meant to keep the vehicle mobile while reducing the number of soldiers directly exposed during firing operations.
Luke Savoie, president and chief executive officer of Elbit America, said: “SIGMA was designed to deliver real overmatch, so Soldiers can fight, survive, and win in the most contested environments.” He added: “This platform provides the might and modernization our U.S. Army artillery formations demand. SIGMA is built for Warriors, made with American grit, and it’s ready now.”
