The United States blew through about a quarter of its supply of high-end THAAD missile interceptors during Israel’s 12-day war with Iran in June, according to two sources familiar with the operation, thwarting attacks at a rate that vastly outpaces production.
US forces countered Tehran’s barrage of ballistic missiles by firing more than 100 THAADs (short for Terminal High Altitude Area Defense) – and possibly as many as 150 – a significant portion of America’s stockpile of the advanced air defense system, the sources said. The US has seven THAAD systems, and used two of them in Israel in the conflict.
Using so many THAAD interceptors in such a short period exposed a gap in the US missile defense network and depleted a costly asset at a moment when American public support for Israeli defense has reached historic lows.
Former US defense officials and missile experts told CNN that the rapid drawdown has also raised concerns about America’s global security posture and ability to regenerate supplies at speed.
Last year, the US procured only 11 new THAAD interceptors and is expected to receive just 12 more this fiscal year, according to the 2026 budget estimates from the Department of Defense.
