The United States has expended more than 850 Tomahawk cruise missiles during the initial four weeks of strikes against Iran under Operation Epic Fury, according to defense reporting. This rapid usage has triggered concerns over stockpile levels, with officials noting the strain on inventories that could take years to replenish given current production rates of approximately 1,000 missiles annually. The operation, which began with large-scale strikes in late February 2026 targeting Iranian military sites, air defenses, and nuclear facilities, has seen sustained use of precision-guided munitions from naval platforms. Reports indicate hundreds of Tomahawks were launched in the first 72-100 hours alone, contributing to broader discussions on munitions sustainability for prolonged conflict. Sources confirm the expenditure forms part of a larger campaign involving US and Israeli forces that has hit thousands of targets.
