Leaked Pentagon assessments reported by US media suggest that if the current strikes on Iran continue beyond 10 days, the United States could face shortages of key missiles. The US and Israel began coordinated attacks on Iran while diplomatic talks over Tehran’s nuclear program and regional activities were still underway. Iran retaliated with missile and drone strikes across the region, targeting Israel and US military assets in several Middle Eastern countries. The Pentagon reportedly cautioned President Donald Trump that a prolonged campaign would carry serious risks, including the high cost of replenishing munitions. Trump, however, insisted that US stockpiles were sufficient to sustain extended operations.

Analysts told Al Jazeera that interceptor missiles such as THAAD, Patriot, and SM‑3 could run low within weeks if the conflict persists. The US military’s Central Command confirmed the use of more than 20 weapons systems, including advanced bombers, drones, and missile defense platforms. Experts warned that manufacturing replacements takes months, and high-end interceptors are designed for limited engagements, not prolonged wars. Secretary of State Marco Rubio noted that Iran can produce far more offensive missiles monthly than the US can build interceptors.

Reports also indicate that the US has already depleted some ship-borne interceptors and suffered friendly-fire losses. Sustaining the campaign is expected to be extremely costly, with early operations estimated to have cost over a billion dollars.
