Washington – The United States used more than half of its entire inventory of advanced THAAD missile interceptors defending Israel during the recent conflict with Iran, according to a report published by The Times of Israel, raising urgent questions about American multi-theater defense capabilities.
The Terminal High Altitude Area Defense (THAAD) system, one of the most sophisticated missile defense platforms in the US arsenal, expended more than 200 interceptors out of an estimated total inventory of fewer than 400 during the Iran-Israel confrontation. Each THAAD interceptor costs approximately $13 million, meaning the defensive operation consumed roughly $2.6 billion in munitions alone.
"This is a wake-up call about the sustainability of our security commitments," said Dr. Thomas Karako, director of the Missile Defense Project at the Center for Strategic and International Studies. "We're learning the hard way that modern missile defense is a consumable resource that cannot be replenished overnight."
The revelation comes at a particularly sensitive moment, as Pentagon planners grapple with the strategic tradeoffs between Middle Eastern security guarantees and Pacific deterrence requirements. China has watched closely as American munitions stocks have been drawn down, first through aid to Ukraine and now through direct defense of Israel.
According to the Times of Israel report, US forces also expended over 100 SM-3 and SM-6 naval interceptors during the same period. Israel itself fired fewer than 100 Arrow interceptors and approximately 90 David's Sling interceptors, underscoring the extent to which American systems bore the defensive burden.
To understand today's headlines, we must look at yesterday's decisions. The THAAD deployments to were authorized during the escalation phase of the conflict, when intelligence assessments suggested was preparing a massive ballistic missile strike. The systems performed effectively, with intercept rates exceeding 90%, but at a cost that has surprised even senior defense officials.
