The United States expended billions of dollars [1] in advanced missile-defense interceptors to protect Israel during a conflict with Iran.
This depletion of critical munitions raises concerns about the U.S. ability to respond to other global threats while replenishing its strategic reserves.
According to reports, the U.S. fired more than 200 THAAD interceptors [2] and over 100 SM-3 and SM-6 missiles [2] to counter Iranian attacks. These operations followed the escalation of the conflict on Feb. 28, 2024 [6].
The scale of the expenditure has led to varying estimates regarding the impact on U.S. readiness. Some reports said that nearly 50% of the Pentagon’s THAAD inventory was consumed [2], while other claims said the depletion reached as high as 90% [2].
Financial estimates regarding the broader cost of the war are also divergent. While some sources said billions of dollars in weapons were lost [1], other discussions have placed a potential $200 billion price tag on the conflict [5].
The deployment of these systems was intended to protect Israel and maintain U.S. strategic influence in the Middle East [1]. The high cost of these interceptors means the U.S. must now balance the immediate needs of its allies, and the long-term requirements of its own national defense stockpiles.

The significant reduction in THAAD and SM-series missile inventories creates a strategic vulnerability for the U.S. military. Because these advanced interceptors require long lead times for production, the U.S. may face a temporary gap in its layered defense capabilities in other theaters, such as the Indo-Pacific, while the Pentagon works to replenish these specific high-cost assets.
