U.S. weapons stockpiles continue to shrink after the recent escalation with Iran, with munitions reserves, including key air-defense missiles, having been heavily depleted. According to Jin10, CNN reported that three people familiar with recent Pentagon data and a latest research report showed there is no sign the Iran conflict will end permanently in the near term.

The Center for Strategic and International Studies said on Monday that the U.S. now has fewer than 827 Patriot interceptors and fewer than 278 THAAD interceptors, a estimate sources said was broadly consistent with internal U.S. government data. The think tank warned that the decline in stockpiles could force the U.S. and its allies to take greater risks in missile interception operations, while no ballistic missile defense system can fully replace Patriot and THAAD.

U.S. President Donald Trump said on Monday that he hopes to replenish "more advanced weapons and equipment" as soon as possible, but added that current stockpiles are still "in good shape." Last week, the chairman of the Joint Chiefs of Staff said the Pentagon would be unable to buy the munitions it needs without additional funding.
