U.S. high-end munitions replenishment would take years, CSIS finds

A CSIS analysis concludes that replenishing U.S. inventories of Tomahawk missiles and Patriot/THAAD interceptors—heavily used in the Iran conflict—will take several years. Projections place Tomahawk replenishment around 2030 and Patriot/THAAD by 2029, meaning a prolonged vulnerability even as defense spending and production capacity expand. Some officials insist inventories are sufficient for a range of scenarios, but experts warn lead times and complex supply chains limit how quickly stockpiles can be rebuilt in a future conflict with China.
