by Christopher Foss

Elbit Systems of Israel is developing a new fully automatic 155mm/52 caliber SP artillery system for the Israel Defense Forces (IDF) which will begin to replace the 155mm/39 caliber M109 tracked SP artillery systems of IDF around 2023, company officials said. Janes.

While many countries still deploy 155mm tracked self-propelled (SP) artillery systems, there is a trend towards 155mm wheeled artillery systems, as they provide strategic mobility due to a less reliance on heavy equipment carriers.

The new artillery system, called SIGMA, is being developed through an initial $125 million contract announced in March 2019. It is based on a US-supplied Oshkosh Defense 10×10 platform selected by the IDF, which uses the trucks for a number of missions. .

The platforms will be equipped with a fully protected control cabin, nuclear biological chemical (NBC) system and full air conditioning for a crew of two or three.

At the rear of the chassis will be mounted an automatic turret armed with a 155 mm/52 caliber cannon with a 23 liter chamber conforming to NATO’s Joint Ballistic Memorandum of Understanding (JBMoU) of NATO, and equipped with a brake muzzle and a smoke extractor.

The 155mm/52 caliber turret system will be remotely controlled from the inside. Additionally, the system provides a manual return mode, or “limp-home mode” of operation, an Elbit Systems spokesperson said. Janes.

The automatic loading system will set the fuze, load the projectile, then the uni-modular artillery loading system (UMACS) with the primers will be automatically loaded through a separate loader.
