U.S. Patriot Missile Stockpiles Critically Depleted Amid Iran War and Ukraine Conflict

Five months of war with Iran have critically depleted U.S. missile stockpiles, consuming roughly 65% of Patriot interceptors, up to 80% of THAAD interceptors, and virtually all long-range ATACMS and PrSM offensive missiles. While President Donald Trump and the Pentagon publicly deny any shortages and threaten leakers with jail time, experts warn the depletion severely compromises U.S. military readiness against China. Meanwhile, the resulting global supply squeeze has left Ukraine's air defenses dangerously exposed to deadly Russian ballistic missile strikes.

U.S. missile stockpile depletion

• ▪The United States military has depleted approximately 65% of its Patriot interceptor missiles and between 38% and 50% of its THAAD interceptors during the five-month war with Iran.
• ▪The Center for Strategic and International Studies estimates that fewer than 850 Patriot interceptors remained in U.S. stockpiles by late July 2026, down from 2,330 before the Iran war.

Iran war munitions consumption

• ▪The United States Army has used up virtually all of its available global stocks of long-range offensive ATACMS and Precision Strike Missiles during the conflict with Iran.
• ▪The United States Navy has expended slightly less than half of its global inventory of ship- and submarine-launched Tomahawk cruise missiles since February 2026.

Patriot interceptor shortages

• ▪The United States has approved the sale of 5,250 Patriot interceptors to Bahrain, Kuwait, Qatar, and the United Arab Emirates to replenish their depleted air defense stocks.
• ▪Saudi Arabia expended approximately 86% of its 2,800 PAC-3 Patriot interceptors during the first 38 days of combat in the Middle East, leaving roughly 400 missiles in April 2026.

ATACMS production replenishment timeline

• ▪Rheinmetall plans to establish an ATACMS production line at its Unterluess plant in Germany in 2027, with initial revenues from the joint venture expected in 2028.
• ▪Rheinmetall CEO Armin Papperger stated that replenishing depleted U.S. military arsenals through planned joint ATACMS production with Lockheed Martin will take much longer than two years.

Trump administration leak response

• ▪President Donald Trump posted on Truth Social threatening long-term jail sentences for those who leaked information regarding the depleted state of U.S. munitions stockpiles.
• ▪Chief Pentagon Spokesperson Sean Parnell and President Donald Trump publicly denied claims of critical weapons shortages, asserting that the U.S. military possesses a deep and powerful arsenal.

Ukraine air defense gaps

• ▪A Russian aerial bombardment on Kyiv overnight on August 5, 2026, killed 21 people after Ukraine's depleted air defenses failed to intercept any of the 24 incoming ballistic missiles.
• ▪President Volodymyr Zelenskyy stated that Ukraine's deliveries of air defense interceptors in 2026 have fallen to just one-third of the levels received during the same period in 2025.
