Core Event
The United States is rebuilding its inventory of key weapons systems after large-scale transfers to Ukraine and the recent Iran-Israel conflict. The rebuild effort has slowed production lines, causing delivery delays for allies that have ordered Patriot missile batteries, Tomahawk cruise missiles and other high-priority munitions.
Background & Context
During the 2022-2023 Ukraine war, the United States supplied the largest share of Ukrainian arms, accounting for 41 % of imports. The Patriot missile system was the most-affected tool, with roughly 600 missiles diverted to Ukraine out of an estimated pre-conflict stock of 2,200. A subsequent Iran-Israel flare-up further strained the Patriot inventory, leaving only about 36 % of pre-war interceptors available. Competition with China and Russia has also increased demand for Tomahawk missiles, of which the United States retains roughly two-thirds of its pre-war stock.
Data & Statistics
- Patriot missiles: ~2,200 before the Ukraine war; ~600 transferred; ~36 % of pre-Iran interceptors remain.
- Tomahawk missiles: Approximately two-thirds of the pre-war stock still on hand; Japan’s order for 400 missiles is being “pushed back in the queue.”
- THAAD systems: The United States, the UAE and Saudi Arabia hold 52-62 % of the global THAAD inventory; deliveries to Saudi Arabia are slated for completion by April 2028.
Official Statements & Responses
War Department Under Secretary for Acquisition and Sustainment Michael Duffey argues that the expanding global threat environment requires a larger defense industrial base to meet warfighter needs. Rep. Michael McCaul (R-Texas), chair of the House Foreign Affairs Committee, warns that delayed deliveries “hurt our alliances” and underscores competition with China, Russia and Iran. CSIS senior advisor Mark Cancian notes that production lines were maxed out during the Ukraine war, limiting the ability to replenish stocks quickly.
