Pentagon reports munitions shortages following Iran conflict

A Pentagon Inspector General report has confirmed a significant shortage in U.S. strategic munitions reserves following Operation Epic Fury, a military intervention against Iran conducted between February 28 and June 30, 2026. The report reveals that munitions spending alone reached approximately $22.3 billion during this period, contributing to a total operation cost of $33.4 billion.

The depletion of stocks has led the United States to warn allied nations of potential delays of up to five years for advanced weapons deliveries. Affected systems include Patriot interceptors, Tomahawk cruise missiles, THAAD batteries, and HIMARS/NASAMS ammunition. The shortage impacts key security partners, including NATO members such as the UK and Poland, as well as Japan.

Industrial production constraints are contributing to the recovery timeline. For example, Tomahawk cruise missiles currently face a lead time of roughly 34 months, and full stock recovery across various systems is expected to take several years. This admission contradicts previous assertions from the Trump administration regarding the abundance of U.S. military reserves.
