A CSIS report states that U.S. Patriot interceptors declined from approximately 2,330 before the conflict to between 759 and 827 after the early April ceasefire, with THAAD interceptors showing modest replenishment from 232-262 to 234-278. Authors Mark Cancian and Chris Park note limited alternatives for ballistic missile defense and increased risk acceptance due to depleted stocks. The findings have prompted differing interpretations regarding military sustainment, foreign engagements, and resource allocation.
