US used up to 20% of its global interceptor missile stockpile during Iran-Israel conflict: report

While supporting Israel during its 12-day war with Iran, the US used an estimated 15 to 20 percent of all of the country’s global arsenal of Terminal High Altitude Area Defense (THAAD) long-range anti-missile systems.

Military Watch Magazine estimated that between 60 and 80 interceptors were utilized during the conflict. Every launch of a THAAD interceptor reportedly costs between $12-15 million, meaning the cost of those interceptors used sits between $810 million to $1.215 billion. The US Army has seven THAAD systems set up in five air defense regiments, with an eighth set to be operational by the end of the year.

The Wall Street Journal reported earlier in June that the US had restocked the THAAD system set up in Israel in 2024.

The Iran-Israel war came to an end after Trump announced on Monday that a "complete and total ceasefire" had been reached by both parties. The conflict began when Israel conducted preemptive strikes on Iran's nuclear enrichment facilities earlier in June. The US conducted strikes over the weekend with bunker-busting bombs against the facilities.

Reports, based on what Defense Secretary Pete Hegseth called a "low confidence" preliminary assessment of the damage, claimed that not much damage was caused to the facilities. Joint Chiefs of Staff chairman Gen. Dan Caine revealed that at the Fordow nuclear facility, "All six weapons at each vent at Fordow went exactly where they were intended to go." Trump told reporters at the NATO summit earlier in the week that the strike was an "obliteration."

He said in regard to whether the war would restart, "I don’t think they’re going to be going back at each other." He noted a letter that stated Iran’s nuclear enrichment facilities were rendered "totally inoperable" during the strikes, and that the strikes "set back Iran’s ability to develop nuclear weapons for many years to come."
