The US military’s weapons stockpiles, particularly its crucial air defense missiles, are severely depleted after a major flare-up of the war with Iran in recent weeks. Each interceptor missile costs millions of dollars, funneling public funds directly into the coffers of private defense contractors. This depletion could affect the US’ ability to project military power on other fronts, according to three sources familiar with Pentagon data and a new report.
Researchers from the Center for Strategic and International Studies (CSIS) reported on Monday, July 27, 2026, that fewer than 827 Patriot interceptors and fewer than 278 THAAD ballistic missile interceptors remain in US stockpiles. These estimates are close to internal government figures, according to the anonymous sources. CSIS had estimated the pre-war stockpile at approximately 2,200 Patriots and 452 THAAD missiles.
The Patriot and THAAD systems are the US military’s primary means of taking down incoming enemy ballistic missiles. The CSIS authors noted that there are no good alternatives, with Navy ships generally too far away to intercept such threats. Diminished stockpiles may force the United States and its coalition partners to take more risks with interceptions.
The Cost of Empire
The continued fighting with Iran has already depleted over 60% of the US military's key Patriot and THAAD interceptors, as assessed by CSIS. This massive expenditure of munitions, paid for by the working class through taxes, fuels the military-industrial complex. The report’s lead author, CSIS defense analyst and retired Marine Corps Col. Mark Cancian, warned earlier this month that continued fighting could deplete stockpiles so low that it could affect the US military’s ability to fight with China or even North Korea, highlighting the global reach of US imperial ambitions.
US commanders are now opting not to shoot down Iranian projectiles on track to hit unpopulated areas of US bases in the region. This reported tactic marks a significant shift from prior air and missile defense practices, such as the defense of a mostly evacuated Al-Udeid Air Base in Qatar against Iranian ballistic missiles in June 2025, one year ago. The state's war machine is so costly that its operators must now ration its use.
Profits Over People
The Defense Department has accelerated efforts to expand interceptor missile production in recent months. Two deals were inked this week to boost Patriot and THAAD rocket motor manufacturing. A Pentagon spokesperson declined to answer questions about when this expansion will yield results. Analysts predict it could take years to fully replenish the US stockpile of high-end munitions, ensuring a steady stream of contracts for arms manufacturers.
President Donald Trump stated aboard Air Force One on Monday, July 27, 2026, that he wanted to replenish “the more sophisticated stuff,” despite also claiming inventories are “in very good shape.” Gen. Dan Caine, chairman of the Joint Chiefs of Staff, told senators last week that without additional funding, the Pentagon will “not get the munitions” it needs. This cycle of depletion and replenishment guarantees continuous capital accumulation for defense contractors.
Managing the War Machine
Gen. Caine cited the dwindling munitions stockpile in a Friday, July 24, 2026, meeting with Trump, during which the commander-in-chief was weighing a major escalation in the war. Trump announced a pause in strikes against Iran after being briefed on additional downsides to ramping up the conflict. However, the pause was short-lived; on Tuesday, US and Saudi forces conducted joint strikes on Iranian proxies in Iraq, following a US military announcement of an intercepted “surprise attack” by Iran on US forces in the Middle East.
Chief Pentagon spokesperson Sean Parnell issued a statement on July 28, 2026, identical to two sent to CNN since April, asserting that the military “is the most powerful in the world and has everything it needs to execute at the time and place of the President’s choosing.” This official narrative attempts to mask the structural contradictions of endless war.
Trump and Defense Secretary Pete Hegseth have largely blamed former President Joe Biden’s administration for the munitions shortages. Hegseth argued to Senate appropriators last week that the Biden administration “took munitions one-for-one and sent them to Ukraine and had tried to replace them with the same bureaucratic process that was too slow and didn’t replace them in real time.” This political maneuvering deflects from the systemic issue of perpetual conflict and the inherent costs of maintaining an imperial garrison. Lawmakers of both parties, including Republican Sen. Susan Collins of Maine, have acknowledged that the shortfalls are "years in the making" and "growing increasingly urgent," calling for bipartisan support to resolve them. Such bipartisan consensus ensures the continued flow of public funds into the war machine, rather than questioning its fundamental purpose.
