The U.S. military faces a potential shortage of Patriot, THAAD, and Tomahawk missiles due to high consumption in recent conflicts [1, 3].
This inventory strain threatens the national defense posture and the ability of the U.S. to provide military aid to allies during active warfare. A depletion of these specific systems would limit both offensive strike capabilities and the ability to intercept incoming aerial threats.
According to a study from the Center for Strategic and International Studies (CSIS) published July 13, the U.S. could run out of these missile systems over the coming years [3]. The shortage is attributed to the combined impact of supporting Ukraine and the recent military campaign against Iran, which saw bombings conclude on July 17 [1].
President Donald Trump (R-FL) has expressed a more immediate concern regarding the timeline of the shortage. Trump said, "If it lasts one more month, we will have no missiles" [2]. To address these gaps, Trump has requested $200 billion [2] in additional funds for the war against Iran.
These warnings follow long-term requests for increased munitions. In May, Volodymyr Zelenskyy said the need for more munitions for air defense systems was critical [3].
Industrial capacity remains a primary hurdle in replenishing these stocks. The current rate of production has struggled to keep pace with the expenditure of munitions in the field, creating a gap between strategic reserves and operational needs [1, 3].
“"If it lasts one more month, we will have no missiles"”
The discrepancy between the CSIS projection of a multi-year shortage and the administration's warning of a one-month window suggests a critical tension between long-term industrial planning and immediate operational readiness. If the U.S. cannot rapidly scale missile production, it may be forced to prioritize domestic defense over international security commitments, potentially altering the strategic balance in regions where Patriot and Tomahawk systems serve as primary deterrents.
