U.S. Defense Stocks Strained by Rapid Use of Interceptors and Precision Munitions in Iran Conflict
U.S. officials say the pace of missile and interceptor use in the war with Iran is depleting stockpiles faster than the defense industry can replenish them, raising concerns about readiness for other potential conflicts.
The United States is facing mounting pressure on its missile and interceptor inventories as the war with Iran intensifies, according to senior military and intelligence officials. Defense analysts say the rapid consumption of advanced air-defense interceptors and precision-guided weapons in the Middle East is outpacing the industrial base’s ability to produce replacements, creating strain on stockpiles that also support other combatant commands.
Officials, who spoke on condition of anonymity, warned that the defense industrial sector cannot quickly scale production of long-range missiles and interceptors transferred to U.S. Central Command, leaving inventories under “mounting pressure” as operations continue. The most heavily used systems include Patriot and THAAD interceptors, as well as GPS-guided bombs equipped with JDAM kits and Small Diameter Bombs, which have become the preferred munitions for many strikes.
"We've got lots of them, we're building more than ever before. Our stockpiles are strong, and they will only get stronger in the future," Defense Secretary Pete Hegseth told "Face the Nation" when asked about the situation.
Admiral Samuel Paparo, head of Indo-Pacific Command, told lawmakers that expanding production of high-end missiles such as Tomahawk cruise missiles and JASSM could take one to two years, a timeline he said would not be sufficient to meet current demands.
"I think it will take one to two years for them to scale ... It won't be soon enough. There are finite limits to the magazine, and I have all the faith in the world that they're being employed judiciously," Paparo said.
The Pentagon has begun reallocating interceptor stocks from other regions, including prepositioned inventories intended for the Indo-Pacific, which has left those commands with thinner margins as the United States seeks to deter Chinese activity around Taiwan. Pentagon spokesman Sean Parnell emphasized that the U.S. military remains capable of executing operations across commands.
"America's 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," Parnell said.
Analysts note that the depletion of systems such as ATACMS, Tomahawks, and JASSMs could take up to five years to replenish, while the demand for air-defense interceptors like THAAD, SM-3 and Patriot missiles is growing even faster. The situation highlights a strategic dilemma of allocating limited munitions between the Middle East and potential future conflicts in Europe or the Indo-Pacific.
