US Faces Critical Missile Shortages Amid Iran War

  • The U.S. Army has reportedly depleted "virtually all" of its Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM) during five months of conflict with Iran.
  • Defense Secretary Pete Hegseth stated in May 2026 that replenishing U.S. inventories could take "months and years" depending on the weapon system.

The United States is facing significant shortages in its long-range precision missile stockpiles after five months of war with Iran, raising concerns about its ability to respond to other global threats. Reports from early August 2026 indicate that the U.S. Army has used “virtually all” of its Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM). Additionally, nearly half of the global inventory of Tomahawk cruise missiles has been expended.

The depletion extends to air defense interceptors, with some reports suggesting that nearly 80% of interceptors for the Terminal High Altitude Area Defense (THAAD) system have been used. Patriot interceptor inventories have also reportedly fallen significantly, from approximately 2,300 before the war to fewer than 827 by late July 2026.

These shortages have prompted warnings from defense analysts and officials that it could take years to replenish these critical munitions. For instance, a May 2026 analysis from the Center for Strategic and International Studies (CSIS) estimated that restoring Tomahawk missile inventories to pre-war levels could take until late 2030, and THAAD interceptors until late 2029. The production and delivery of a Tomahawk missile alone can take around 47 months.

The ongoing conflict in Ukraine, as well as support for Israel and operations against Houthi forces in the Red Sea, have further strained U.S. munitions stockpiles. While the White House and Defense Secretary Pete Hegseth have publicly denied claims of significant shortages, stating that the U.S. has “more than enough munitions” and is increasing production, reports suggest that concerns over dwindling stocks have influenced military decisions. Some reports indicate that anxieties over munitions stocks were a factor in a decision in late July 2026 to not proceed with a major two-week strike campaign on Iran.
