U.S. Patriot Missile Stockpiles Have Dropped by Two-Thirds Since the Iran War Began, Officials Say
The United States‘ stockpile of Patriot missile interceptors has fallen from more than 2,300 to around 800 since President Trump launched the war against Iran on February 28, 2026, according to new analysis — a decline that’s leaving Ukraine, Gulf allies, and the U.S. itself competing for a weapon that simply isn’t being manufactured fast enough to meet demand.
The Scale of the Shortage
The Center for Strategic and International Studies, a Washington-based think tank, said in a July analysis that the U.S. had more than 2,300 Patriot interceptors before the Iran war began; that number now sits at around 800, according to NPR’s reporting. The exact figure for U.S. Patriot stockpiles is classified, but a U.S. official who spoke to NPR on condition of anonymity, given the sensitivity of the issue, said the CSIS figures appeared accurate.
The core problem is straightforward: production hasn’t kept pace with combat consumption. Raytheon, now operating as RTX, manufactures the Patriot missile battery system itself, while Lockheed Martin produces the interceptor missiles that run through it, each costing around $4 million. Together, the two companies have been producing fewer than 1,000 Patriot interceptors per year — a rate that appeared adequate before demand surged simultaneously from the Russia-Ukraine war and the U.S.-Iran conflict. Both companies have said they plan to ramp up production, though it remains unclear how long it will take to rebuild — or even meaningfully grow — inventories worldwide.
Ukraine Feels the Shortage Acutely
The consequences of the shortfall have already shown up on the battlefield. Russia’s massive air assault against Ukraine before dawn on Saturday, August 1, included 27 ballistic missiles, many striking the capital, Kyiv, killing nine people and wounding more than 30, according to NPR. While Russia conducts airstrikes on Ukraine almost nightly, what made Saturday’s attack especially notable was Ukraine’s inability to defend against it.
Ukrainian President Volodymyr Zelenskyy said the military shot down just one of the 27 ballistic missiles fired that night. “Only one ballistic missile was intercepted, simply because there are no interceptors for the Patriot systems,” Zelenskyy wrote on social media, according to NPR’s reporting.
Ukraine began receiving Patriot air defense batteries roughly three years ago and has used them effectively to limit damage from Russian attacks, viewing the system as central to its ability to defend against ballistic missile strikes. The country has repeatedly requested both additional Patriot systems and, more urgently now, additional interceptor missiles to keep its existing batteries operational. NPR noted that President Trump has recently walked back a previously promised boost to Ukraine’s missile defense supplies.
The U.S. and Its Gulf Allies Are Also Competing for Supply
Ukraine’s shortage is only part of the picture. The U.S. itself has grown concerned about its own Patriot stockpiles, which have declined sharply during the ongoing war with Iran. At the same time, U.S. allies in the Gulf region are separately wondering how quickly they’ll be able to replenish their own Patriot inventories if fighting with Iran resumes and their current supplies run out.
That combination — a active U.S. conflict, an active European conflict, and nervous Gulf allies stockpiling in anticipation of renewed hostilities — has created three simultaneous sources of demand pulling against the same limited annual production capacity.
A Public Disagreement Over Whether There’s Actually a Shortage
The severity of the shortfall has become a point of contention within the administration itself. In June, Defense Secretary Pete Hegseth dismissed news reports about a Patriot missile shortage as a “manufactured story,” according to NPR. That characterization sits awkwardly alongside Hegseth’s own comments two months earlier, in which he acknowledged that replenishing the country’s missile stockpiles could take “months and years” — an acknowledgment that, on its face, describes a materially depleted supply even if Hegseth avoided using the word “shortage” directly.
Why Ramping Up Production Isn’t Simple
Both Raytheon/RTX and Lockheed Martin have stated intentions to increase Patriot production, but scaling up missile manufacturing isn’t a quick process. It typically involves expanding specialized supply chains, training additional skilled workers, and, in many cases, building new manufacturing capacity — steps that can take years even under strong political and financial pressure to move faster. In the meantime, the gap between global demand and available supply is being managed through allocation decisions about which country’s needs take priority at any given moment, decisions that inevitably leave some allies waiting longer than others.
FAQ
How many Patriot interceptors does the U.S. currently have? The exact figure is classified, but according to a Center for Strategic and International Studies analysis that a U.S. official told NPR appeared accurate, the number has fallen from more than 2,300 before the Iran war began to around 800 as of the analysis in July 2026.
Why is there a shortage of Patriot missiles? Raytheon (RTX) and Lockheed Martin together have been producing fewer than 1,000 Patriot interceptors per year, a rate that hasn’t kept pace with the combined demand from the ongoing Russia-Ukraine war and the U.S.-Iran conflict.
How is the shortage affecting Ukraine specifically? During a Russian attack on August 1 involving 27 ballistic missiles, Ukraine was able to intercept only one, which President Zelenskyy attributed directly to a lack of available Patriot interceptors.
How much does each Patriot interceptor cost? Approximately $4 million per missile, according to NPR’s reporting.
Has the Trump administration acknowledged the shortage? Statements have been mixed. Defense Secretary Pete Hegseth called shortage reports a “manufactured story” in June, but had separately acknowledged in April that replenishing stockpiles could take “months and years.”
Conclusion
The gap between how fast Patriot interceptors can be manufactured and how fast they’re being used up in active combat has turned a specialized piece of military hardware into one of the most consequential bottlenecks of 2026’s overlapping conflicts. With Ukraine publicly describing near-total interceptor shortages during recent attacks, U.S. stockpiles down by roughly two-thirds since February, and Gulf allies watching nervously for signs of renewed fighting with Iran, the production ramp-up promised by RTX and Lockheed Martin is likely to remain a closely watched — and likely slow-moving — story in the months ahead.
