Tehran's forces have carried out frequent missile and drone attacks in the Middle East since the breakdown of the US-Iran ceasefire, raising renewed concerns about Washington's supply of the weapons needed to intercept them.
Highlighting the issue, the US military said it shot down multiple ballistic missiles fired by Tehran in an "attempted surprise attack" this week, following a deadly Iranian strike on American troops in Jordan earlier this month.
Some lawmakers have raised questions about whether the United States has sufficient munitions since early in the war, which began with US-Israeli strikes in late February before the fighting largely halted under an April ceasefire, only to resume in recent weeks.
"We have depleted our interceptors... which are, obviously, necessary to protect American troops," US Senator Chris Van Hollen said Sunday on ABC's "This Week."
"We are depleting these every day, despite the fact that we could face other potential conflicts around the world," the Democrat added.
Defense Secretary Pete Hegseth has previously dismissed fears about Washington's weapons supplies, and the US military has not publicly released details about how many interceptors it has.
But US media outlets have reported that General Dan Caine, the chairman of the US Joint Chiefs of Staff, has raised concerns about falling US interceptor supplies.
President Donald Trump was asked about the issue on Monday and said that while stocks are sufficient, he wants more.
"We have a lot of ammunition, different types," Trump told journalists aboard Air Force One, while adding: "For some of the more sophisticated stuff, we'd certainly like to have more."
Trump took aim at Joe Biden, saying "so much was given to Ukraine" by the Democratic president, who sought to help Kyiv's forces defend against repeated Russian missile and drone attacks.
- 'Extensive use of interceptors' -
But Trump's war against Iran has resulted in major reductions in US weapons supplies.
An analysis by the Center for Strategic and International Studies (CSIS) think tank released this week found that US stocks of key Patriot and THAAD air defense missiles have been slashed by the conflict.
Before it began, the United States had more than 2,300 Patriot and more than 450 THAAD interceptors -- figures that CSIS estimated have been roughly halved or more in the subsequent five months of war.
"The air defense campaign has been largely successful with high -- though not perfect -- interception rates," but "this has required extensive use of interceptors," CSIS said.
The United States is pushing hard for defense companies to increase the pace at which weapons including interceptors are produced.
Trump referred to these efforts on Monday, saying: "Plants are being built. A lot of equipment is being built. The Patriots, in particular, are being built."
The Defense Department announced a $58.6 billion, seven-year deal with Lockheed Martin for Patriot missile production this week that the company said will deliver "critical interceptors into the hands of warfighters at unmatched speed."
But the United States still faces dangers from interceptor shortfalls, CSIS said in its analysis.
"Diminished stockpiles may force the United States and its coalition partners to take more risks with interceptions," while "expended munitions create a near- to medium-term risk for US readiness to fight a war against China in the western Pacific," it said.
Asked if the Pentagon was concerned about current munitions supplies, chief spokesman Sean Parnell said the US military "has everything it needs to execute at the time and place of the president's choosing."
"We have executed multiple successful operations across combatant commands while ensuring the US military possesses a deep arsenal of capabilities to protect our people and our interests," he said.

Executive Summary
Full Take
The narrative centers on the tension between immediate operational success and long-term strategic sustainability, framed by evolving supply dynamics. The reporting juxtaposes official assurances of sufficient capability from the Pentagon with internal concerns raised by senior staff and public figures regarding material depletion. This creates a dynamic where stated readiness conflicts with quantitative reality, forcing a public discussion about risk tolerance in ongoing conflicts. A key pattern emerging is the strategic deflection: the focus shifts from the supply deficit itself to the successful interception rates or the promises of future production, which serves to manage immediate anxiety while obscuring systemic vulnerabilities. The push for increased production deals highlights a pivot toward industrial solutions as a necessary countermeasure against depleting stockpiles, suggesting that logistical endurance is becoming an explicit strategic concern rather than an implicit assumption. The underlying implication is how national security calculations must adapt when the cost of kinetic operations leads to demonstrable attrition of defensive assets.
Bridge Questions: If production timelines are aggressive, what alternative sustainment strategies exist beyond traditional procurement? How should policymakers balance immediate operational needs against long-term industrial capacity concerns regarding coalition partners? What metrics would accurately reflect readiness given the reported reduction in physical assets versus demonstrated interception success?
