Fully American-Made Mobile Cannon Showcases 360-Degree Firepower at Huntsville Defense Expo
Huntsville, Wednesday, 18 March 2026.
Debuting at the Huntsville defense expo, Elbit America’s SIGMA system is the only fully US-manufactured wheeled howitzer, offering revolutionary 360-degree firing to modernize domestic military procurement.
Technical Specifications and Battlefield Dominance
The engineering behind the SIGMA cannon reflects a broader military push toward highly mobile and lethal ground forces [alert! ‘General military trend context provided to frame the specific metrics’] [1][GPT]. The system operates on a heavy-duty 10x10 wheeled platform and features an automated 155mm turret capable of 360-degree firing [1]. In terms of sustained firepower, the SIGMA is equipped with a 40-round onboard magazine and can achieve a maximum firing rate of eight rounds per minute [1]. At this peak operational tempo, the cannon would deplete 20 percent of its total onboard magazine capacity in a single minute of continuous firing. Furthermore, the howitzer is compatible with all variations of 155mm munitions currently held in the U.S. Army’s arsenal, ensuring seamless integration into existing logistical frameworks [1].
Alignment with Army Transformation Initiatives
The introduction of advanced hardware like the SIGMA aligns closely with the U.S. Army’s ongoing modernization and transformation efforts, which are a focal point of the AUSA symposium [4]. The military is actively investing in new technologies, artificial intelligence, and data analytics to ensure readiness across all environments [4]. To support this operational shift, the Army is hosting specialized panels during the symposium, including a March 24 session focused on how Army civilians drive continuous transformation through technology integration and data-driven decision-making [4].
