Israel’s Elbit Systems and a consortium of Israeli, German and US firms are facing off in a high-stakes bid to modernize Israel’s Artillery Corps with new self-propelled guns.

The two candidates for more than $1 billion in multiyear procurement awards were downselected by Israel’s Ground Forces Command from a pool of four prospective bidders, officers here said.

Designated as a priority program by the Israel Defense Forces’ (IDF) General Staff with approved multiyear funding for a first brigade, the future gun will replace 50-year-old M109 howitzers.
