During the confrontation with Iran between February 27 and July 27, the United States faced a significant reduction in air defense assets, the Center for Strategic and International Studies (CSIS) reports.

Accordingly, the US spent more than 1,500 Patriot missiles and about 200 interceptor missiles of the THAAD (Terminal High Altitude Area Defense) missile defense system.

The resumption of hostilities has further reduced the US arsenal reserves, although Iranian missile launches are still less frequent than before the ceasefire. The air defense campaign was generally successful, the CSIS noted.

According to analysts, during this period, the US military used about 1,500 to 1,570 Patriot missiles, and the number of THAAD interceptors decreased by 174 to 218 units. As of February 27, the US had about 2,330 Patriot missiles and 452 THAAD interceptor missiles in its arsenal. By the end of July, however, the stockpile had decreased to 759 to 827 Patriots and 234 to 278 THAAD missiles.

CSIS added that such a reduction could complicate the capabilities of the US and its allies to repel potential missile attacks.

According to CSIS, there is no complete replacement for the Patriot and THAAD systems in the fight against ballistic threats, and ship-based missile defense systems may not be sufficiently accelerated due to their distant location from the conflict zone.
