US Pauses Iran Campaign Amid Concerns Over Depleted Weapons Stockpiles

President Donald Trump delivered a firm message to defence industry leaders at the Pennsylvania Defense and Innovation Summit this month: build more weapons and build them faster. Flanked by CEOs of America’s largest defence contractors and Secretary of War Pete Hegseth, Trump stressed the importance of production speed to maintain US military superiority. ‘We have the best quality in the world,’ Trump told the arms makers at the US Army War College. ‘But we need a little more speed.’ The statement comes amid deep concerns about the depletion of advanced US weapons stockpiles after nearly 40 days of intensive combat operations in Iran during Operation Epic Fury earlier this year. The US government reported that the war cost US$37.5 billion, with the majority allocated to munitions. Data from the Center for Strategic and International Studies (CSIS) paints a worrying picture of ammunition stocks that are difficult to replace in the short term. Mark Cancian, a senior adviser at CSIS, stated that producing a single missile can take one to five years. Although Trump denied any shortage in an interview with the Wall Street Journal, Pete Hegseth recently requested an additional US$87 billion from the Senate Appropriations Committee to address critical shortfalls in military equipment. The dwindling stockpile condition creates what Cancian called a window of vulnerability. This is crucial given the potential for conflict in the Pacific over Taiwan, which some US military planners predict could occur before 2027. Pressure is also coming from Europe. Ukrainian President Volodymyr Zelensky expressed concern over the depletion of US air defence reserves. By comparison, the US produces around 60 to 65 missiles per month, while 803 missiles were used on just the first day of Operation Epic Fury. Despite strained US stockpiles, the White House remains optimistic because Iran’s defence capabilities are considered far more devastated. White House spokesperson Anna Kelly stated that the US military has more than enough munitions to serve President Trump’s strategic objectives. Jason Brodsky from United Against Nuclear Iran added that US and Israeli strikes significantly degraded Tehran’s defence industrial base. Iran’s capacity to produce missiles and drones on a large scale was largely destroyed, forcing them to focus remaining stocks on threatening the Strait of Hormuz. For now, Washington is betting it can navigate this transition period by relying on diplomacy and industrial pressure while waiting for Made-in-America weapons production capacity to catch up.
