Semafor reported, citing US officials, that Israel has informed Washington it is running critically low on Ballistic missile interceptors1. Israel entered this conflict already depleted: last summer's Twelve-Day War consumed interceptor stocks that had not been fully replenished. The IDF denied the report, stating it is using fewer interceptors than anticipated2. Foreign Minister Gideon Sa'ar was categorical: "The answer is no"3. Israel Hayom reported the IDF suspects Iranian disinformation behind the story4.
The denial sits uneasily beside the Israeli cabinet's approval, the same weekend, of NIS 2.6 billion (~$826 million) in emergency defence procurement described as "urgent and essential." Arrow interceptors cost $2–3 million each; David's Sling falls in a similar range. At Iran's current firing rate — seven salvos in a single night — even high interception rates burn through expensive, hard-to-replace munitions at speed. Governments do not rush $826 million to defence ministries experiencing no shortage.
Money alone does not solve the problem. Arrow and David's Sling are produced by Israel Aerospace Industries and Rafael Advanced Defense Systems in partnership with Boeing and Raytheon. These are not commodity items — they require specialised components with production lead times measured in months, not weeks. Spending $826 million secures a place in a production queue that was already contested between Israeli requirements, US Patriot PAC-3 allocations, Gulf state orders, and Ukraine's ongoing needs. The queue existed before this war; the war has made it longer.
What has changed is the threat geometry. On 8 March, IRGC commander Majid Mousavi declared all future strikes would carry warheads exceeding one tonne. On 10 March, Iran and Hezbollah launched their first declared joint operation — five hours of coordinated fire on more than 50 Israeli targets. Last week, 11 Iranian cluster missiles penetrated Israeli defences, one dispersing 70 submunitions over a residential area in Shoham. Israel's air defence must now defeat heavy warheads from the east, cluster munitions designed for area saturation, and continuous rocket fire from Lebanon's south — simultaneously. Whether the stockpile is "critically low" or merely declining faster than it can be replaced, the burn rate at current Iranian tempo exceeds any plausible replenishment schedule.
