The Israel Defense Forces has used its new Ro’em self-propelled howitzer in combat for the first time, firing the system during artillery strikes in southern Lebanon.
Units from the 282nd Artillery Brigade brought the wheeled system, also known as the SIGMA 155, into action to support ground operations near the border. The howitzers were used to target Hezbollah rocket and anti-tank launch sites, with the military describing the mission as successful and noting that it achieved its objectives.
This marks the first operational use of the Ro’em in a live combat setting, moving the system from development and testing into frontline service. The deployment is part of a wider effort to modernize Israel’s artillery forces, replacing older platforms that have been in service for decades.
Developed by Elbit Systems, the Ro’em is a fully automated self-propelled howitzer mounted on a 10×10 wheeled chassis. It is built to deliver fire at ranges of up to 40 kilometers and can sustain a firing rate of several rounds per minute. Its mobility allows it to shift positions quickly, reducing the risk of being targeted after firing.
During the recent operation, the system was positioned near the Lebanese border, where it provided fire support to maneuvering forces. The ability to respond quickly and engage targets at range is a key part of its role, particularly in environments where threats can emerge with little warning.
Compared with the M109 tracked howitzers currently in use, the Ro’em offers longer reach, faster response times, and greater mobility. Its wheeled design allows it to move more efficiently along road networks, while its automated systems streamline the firing process and reduce the burden on the crew. That automation also shortens the time between identifying a target and opening fire. Faster response can be critical when dealing with mobile or time-sensitive threats, such as rocket launch teams.
The IDF plans to introduce the system gradually, replacing M109 platforms as units transition to the new equipment. The first fully operational formation equipped with the SIGMA 155 is expected within three years, with wider deployment across regular artillery units planned by the end of the decade.
The Ro’em is intended to remain in service for decades, with the military projecting a lifespan of at least 50 years. Its design allows for upgrades over time, helping it keep pace with changing operational needs.
Its first use in southern Lebanon provides an early look at how the system performs under real conditions. By bringing it into active operations, the IDF is gaining practical experience that will shape how it is deployed more widely in the coming years.
