The United States reportedly used 60–80 THAAD interceptors in just 12 days to defend Israel from Iranian missile attacks, according to Military Watch Magazine. Each interceptor costs $12–15 million, totaling up to $1.2 billion. The expense highlights the unsustainable cost gap between defense and offense in prolonged conflict. Iran’s barrage included high-speed missiles like Fattah-1, traveling at Mach 15. With limited annual production of THAAD units, replenishment could take years. The system was deployed in Israel ahead of rising tensions with Iran.
