The White House and Pentagon have rejected reports that five months of war with Iran have left the United States dangerously short of offensive and defensive munitions. President Donald Trump said the US had “far more munitions than anyone in the world,” while Pentagon spokesman Sean Parnell said the military had everything it needed to carry out its missions.
Experts and recent media reports have raised particular concern about Patriot and Terminal High Altitude Area Defense, or THAAD, interceptors. They say depleted stocks could make it harder to protect US forces, support allies and deter other military powers, even as Washington moves to increase weapons production.
At a glance:
- CNN reported that the US had used about 80 percent of its pre-war THAAD interceptors and about half of its Patriot interceptors; Defense Secretary Pete Hegseth disputed the figures.
- A CSIS analysis published on July 27 estimated that just over a third of Patriot interceptors and about half of THAAD interceptors remained, and said rebuilding pre-war stocks could take at least three years.
- Reuters and CBS News reported that the military had used most of its Army Tactical Missile Systems and Precision Strike Missiles.
- The administration has requested $95bn in its Fiscal Year 2027 defence budget and a further $21bn request to replenish weapons stocks.
What US officials are disputing
Trump attributed some Patriot interceptor transfers to Ukraine and Europe to the administration of former President Joe Biden, following Russia’s invasion of Ukraine. He also pointed to efforts to expand weapons production and said the US would provide more weapons to allies as production increased.

Parnell said the US military had carried out successful operations while maintaining a deep arsenal to protect US personnel and interests. Defense Secretary Pete Hegseth separately rejected the reported 80 percent depletion figure for THAAD interceptors and disputed the description of the situation as dangerous.
What the reports and analysis say
The estimates differ. CNN, citing sources, reported that the military had depleted about 80 percent of its pre-war THAAD interceptors and about half of its Patriot interceptors. The Center for Strategic and International Studies calculated on July 27 that just over a third of Patriot interceptors and about half of THAAD interceptors remained.
Reuters reported that sources described virtually all of the Army Tactical Missile Systems and Precision Strike Missiles as used. Those weapons are offensive, long-range missiles, unlike Patriot and THAAD interceptors, which are used for air and missile defence.

CSIS assessed that restoring interceptor supplies to pre-war levels could take at least three years, even with additional funding. The figures have not been reconciled publicly by the administration and should be understood as competing assessments rather than a single confirmed inventory count.
Why interceptors matter to US forces
Retired US Marine Corps Colonel Mark Cancian, a senior adviser with CSIS, said shortages of ATACMS and PrSM could force the military to rely more on air-delivered or sea-delivered weapons, or send aircraft closer to enemy air defences. That could increase risks to personnel and require more effort to suppress opposing defences.
Cancian described interceptor shortages as more serious because there are few direct substitutes. He said every interceptor used reduces the stock available for future attacks and can weaken deterrence against military powers such as China. NBC News and other US media have reported that the military has taken a more selective approach to intercepting attacks considered less likely to cause major damage, a tactic that may preserve stocks but increase the risk of miscalculation.
Potential effects on allies
The United States supplies Patriot missiles and, to a lesser extent, THAAD interceptors to allies in the Middle East. The Trump administration announced an additional $25bn in Patriot interceptor sales and related services to Kuwait, Bahrain, the United Arab Emirates and Qatar in May. The US has also supplied the systems to Saudi Arabia, Jordan and Israel.
Cancian said Washington could hold back more interceptors to rebuild its own stocks, potentially affecting allies. Ukraine’s President Volodymyr Zelenskyy has also warned of declining Patriot deliveries. On Wednesday, he said allies had supplied Ukraine with one-third as many air-defence interceptors in 2026 as during the same period a year earlier.
Questions readers ask
Are US munitions officially confirmed to be dangerously low?
No. The White House and Pentagon reject that characterisation. Public reports and CSIS analysis offer different estimates of remaining interceptor stocks, and officials have not publicly released a matching inventory breakdown.
How quickly could US interceptor stocks recover?
CSIS assessed that returning supplies to pre-war levels could take at least three years. Experts have stressed that funding can support production, but manufacturing capacity and time limit how quickly stocks can be rebuilt.
