According to estimates by the Center for Strategic and International Studies (CSIS), the U.S. military expended approximately 1,060 to 1,500 modern Patriot interceptors during roughly seven months of conflict with Iran. This expenditure is equivalent to the total number of Patriot interceptors the U.S. military procured over about 19 years, leaving only about one-third of the pre-war stockpile of roughly 2,200 to 2,330 interceptors.

In September 2026, the US think tank Center for Strategic and International Studies (CSIS) released a report stating that, due to consumption from the war in Iran, the US military's existing stockpiles of precision munitions such as Patriot, Tomahawk and THAAD would likely last only about one month if a conflict broke out with China, and that replenishing them to the level needed for operations against China would take years, drawing widespread coverage from various quarters.
