US Missile Stockpiles Depleted After Iran Conflict, Raising Pentagon Concerns

A Reuters report reveals that five months of conflict with Iran have significantly depleted the United States' stockpile of precision missiles, raising concerns about readiness for future confrontations with powers like China and Russia. According to four sources familiar with the matter, the US military has nearly exhausted its supply of ATACMS ground-to-ground missiles and a large portion of the newer long-range PrSM missiles, both critical for potential future conflicts with major adversaries. Additionally, US air defense systems have seen substantial usage, with estimates from the CSIS think tank indicating that about 65% of Patriot missile interceptors and at least 38% of THAAD interceptors have been expended. The US also reportedly used nearly half of the global inventory of Tomahawk cruise missiles during the campaign.

This sharp reduction in precision weapon stockpiles has become a key topic in recent White House and Pentagon discussions, as limited inventories could hinder rapid responses to new crises and weaken deterrence against rivals. The extensive missile use was partly due to a strategic decision to prioritize remote strikes over risking manned aircraft over Iranian territory, which, while reducing pilot risk, heavily drained strategic ammunition reserves. President Donald Trump dismissed the report, asserting that the US has "much more ammunition than any other country in the world" and that defense industries are producing munitions at an unprecedented rate to replenish stocks. However, security officials and analysts told Reuters that current production rates are unlikely to quickly offset the depletion caused by the Iran conflict.

In contrast, Israeli defense sources reject concerns about ammunition shortages, stating that the Israel Defense Forces maintain sufficient munitions to handle all operational scenarios, including a potential new conflict with Iran. They emphasize ongoing procurement, production, and replenishment efforts ensure the IDF's operational readiness remains intact.
