Patriot and THAAD interceptor inventories are down by roughly a third to nearly 80 percent, and analysts say full replenishment could take years.

Five months of sustained U.S. military operations against Iran have left American missile defense stockpiles at their lowest levels in years, according to defense analysts and multiple people familiar with internal Pentagon assessments, raising questions about the country’s readiness to respond to a separate high-intensity conflict.
A recent analysis from the Center for Strategic and International Studies estimates the United States has between 759 and 827 Patriot interceptors remaining, roughly a third of its prewar inventory, and between 234 and 278 THAAD interceptors, down from 452 before the campaign began. Other sources familiar with the latest Pentagon inventory data put the THAAD depletion even higher, at nearly 80 percent of pre-conflict levels.
The systems are among the military’s primary tools for shooting down ballistic missiles aimed at U.S. troops, bases and allied populations. Analysts say the erosion is significant not because of any near-term shortfall against Iran, but because of what it signals about the country’s capacity to fight on a second front. “There are no good alternatives to Patriot and THAAD for ballistic missile defense,” CSIS analysts Mark Cancian and Chris Park concluded in their assessment, warning that rebuilding the inventories will take years.
It is a feasible concern given production timelines. Lockheed Martin currently manufactures roughly 96 THAAD interceptors annually, though the Pentagon has struck a new agreement aimed at quadrupling that capacity. Existing Patriot and precision-strike missile contracts show two- to three-year gaps between order and delivery, meaning even an aggressive ramp-up in manufacturing will not meaningfully restore stockpiles before 2028 or 2029.
The Defense Department has pushed back on the characterization that readiness is compromised. Officials have consistently maintained the military retains sufficient interceptors for any plausible scenario in the Iran conflict itself, and this week the Pentagon announced new agreements with Northrop Grumman and Lockheed Martin to accelerate Patriot and THAAD production. Still, the department has declined to confirm specific inventory figures publicly.
The stakes extend well beyond the Middle East. Washington’s ability to deter China in the Indo-Pacific and to reassure European allies depends substantially on maintaining an adequate supply of precision-guided munitions. A prolonged reduction in available interceptors could complicate U.S. commitments abroad at a moment when adversaries are watching closely how the country manages competing demands on its arsenal.
