SIGMA 155 Howitzer

Full Specifications

SIGMA 155 Self‑Propelled Howitzer

The SIGMA 155 is a new generation self‑propelled howitzer built by Elbit Systems in Israel and positioned as a candidate for modern artillery forces, including in the United States Army’s Next Generation Howitzer initiative.

SIGMA 155 stands out as one of the most advanced 155 mm artillery platforms fielded in recent years. It was developed to replace legacy tube artillery like the M109 and to give ground forces rapid, automated fire support with fewer crew and faster repositioning.

Modern Artillery for 21st Century Battlefields

Built around a NATO‑standard 155 mm L52 gun mounted on a 10×10 wheeled chassis supplied by Oshkosh Defense, the SIGMA 155 pushes automation farther than most self‑propelled guns in service today. It integrates auto‑loading, remote‑controlled turret functions, and advanced fire control that lets it load, aim and fire with minimal human work.

In June 2024, IDF artillery crews fired the first systems in testing, and full operational induction is scheduled for the mid‑2020s. The platform is built to stay in service for decades, with design emphasis on quick shoot‑and‑move operations to avoid counter‑battery fire.

Key Capabilities and Combat Use

SIGMA can transition from travel to firing mode in about a minute, fire up to eight rounds per minute, and carry around 40 rounds onboard. Its primary range is roughly 40 km, with export variants planned to reach 80 km with extended‑range ammunition.

The system only needs a crew of three and is designed to integrate into networked command‑and‑control setups. This lets it receive targeting data from drones, radar and other sensors, improving accuracy and coordination with other ground and air assets.
