How many weapons has the U.S. used in Iran war?

February 28 marked a renewed U.S.-Israel campaign against Iran, dubbed Operation Epic Fury, with weeks of sustained bombings and additional warships deployed. The offensive has relied on missiles, drones, and other munitions, while CSIS analysis indicates stockpiles are strained but currently sufficient to sustain operations for now. Restocking to prewar levels is expected to take years due to budget approvals, production timelines, and allocations to U.S. allies. The Trump administration is pushing for a $1.5 trillion defense budget, a 42% increase over current levels, even as Democrats question stockpile sustainability and Republicans push for more production and funding, with some pointing to Ukraine aid as a complicating factor. CSIS identifies seven key munitions heavily used in the Iran war: Patriot, THAAD, Tomahawk, SM-3, SM-6, JASSMs, and PrSM. More than 1,000 Tomahawk missiles have been fired, nearly a third of the prewar inventory of about 3,100, while Patriot missiles show greater depletion at about 1,060–1,430 of a stockpile of 2,330; PrSMs and THAAD interceptors are also heavily drawn down.
