The Pentagon is deploying a Patriot battery from Texas to Israel amid preparations for a possible military operation against Iran. Washington has warned its Persian Gulf allies of a possible short and intense campaign after the November 3 US midterm elections. US missile stocks are critically depleted. CSIS estimates that the US fielded 1,060-1,430 interceptors in the first 39 days, consuming 45-61% of its pre-war arsenal. Renewal is hampered by limited production capacity, with shortages likely to persist until 2030. The additional battery is intended to strengthen Israel's existing layered defense system (Arrow, David's Slingshot, Iron Dome) against the fall of mass rockets.
