Current and former officials describe the challenge as a “zero-sum” competition for missile defense inventories between the Middle East and Europe. Systems needed to shield U.S. bases from Iranian retaliation are the same ones drawn down by support for Ukraine and the ongoing defense of Israel.
Iran has already launched counterattacks near U.S. positions in Bahrain, Qatar, the United Arab Emirates, Kuwait and Jordan, with host governments reporting interceptions. A U.S. official told Fox News Digital that no American service member fatalities or injuries had been reported as of Saturday.
During the June 2025 Iran–Israel conflict, U.S. forces fired more than 150 Terminal High Altitude Area Defense interceptors, about a quarter of the global inventory, along with a large number of ship-based standard missiles. Defense assessments attribute the shortfall to the dual pressure of supplying Ukraine and reinforcing the Middle East, noting that replenishing high-end systems can take more than a year because production lines are optimized for peacetime.
Independent groups estimate that the United States produces roughly 600 to 650 Patriot PAC-3 MSE missiles annually under expanded contracts. Analysts warn that in a high-intensity war with a near-peer adversary such as Iran, where multiple interceptors may be required for a single incoming missile, even a year’s production could be consumed within weeks.
“The Department of War has everything it needs to execute any mission at the time and place of the president’s choosing and on any timeline,” Chief Pentagon spokesman Sean Parnell said in response to readiness questions. Retired Air Force Gen. Charles Wald, former deputy commander of U.S. European Command, said the United States can surge conventional strike munitions and draw from prepositioned stocks if ordered.
“From a conventional munition standpoint, we can always fly in more weapons from around the world,” Wald told Fox News Digital. “There are a lot of weapons stored there with this type of mission in mind.”
He cautioned that the greater constraint lies in defensive systems. “The issue will be defensive weapons — Patriot, SM-3, and the Arrow system in Israel,” Wald said. “You can never have enough defense.”
Israeli defense analyst Ehud Eilam underscored the same concern. “There is a limit to how many THAAD missiles can be used,” he said. “These are not systems you can reproduce overnight.”
Iran is believed to possess between 1,500 and 2,000 ballistic missiles, along with drones and shorter-range rockets capable of striking U.S. bases and Gulf energy infrastructure. Analysts note that in a sustained exchange, interceptor inventories rather than offensive strike weapons could become the binding constraint.
Some experts also pointed to the psychological effect of recent U.S. operations, including Operation Absolute Resolve in Venezuela in January 2026 and the 12-day exchange with Iran in summer 2025. One former defense official cautioned that success in limited operations can create misplaced confidence in more complex scenarios.
“Iran is a very different problem,” the official said, describing it as a large, heavily armed state with extensive missile forces and regional proxy networks. Wald echoed that warning, saying, “You don’t want to get people so confident that you don’t consider the risks. It’s not going to be as clean or pure as, say, Venezuela was, or the 12-day war.”
Officials also warn that retaliation from Iran and allied militias in Iraq, Lebanon and Yemen could widen the conflict. “Once these things break, you own what follows,” one former official said, stressing the risk that missile and proxy attacks could quickly escalate beyond a limited strike.
Wald added that even a successful military phase would not resolve political uncertainty. “Bombing Iran is not going to do regime change,” he said, emphasizing that air power can degrade capability but cannot guarantee a stable political outcome.
Beyond military considerations, officials highlight economic risks, noting that roughly one-fifth of the world’s oil supply transits the Strait of Hormuz. A sustained regional conflict would also draw on naval and air-defense assets that planners must weigh against long-term challenges from China and ongoing commitments in Ukraine, as President Donald Trump seeks confidence in how any Iran contingency would unfold.
