The Pentagon has ordered a pause on shipments of Patriot missile interceptors, precision-guided 155 mm artillery shells and other high-end munitions that were already staged in Poland for onward movement to Ukraine.
The hold, issued after a stockpile review by Under Secretary of Defense for Policy Elbridge Colby, reflects concern that U.S. reserves have dipped below the levels required for domestic war plans.
Colby—an architect of the 2018 National Defense Strategy and a longtime advocate of pivoting resources toward deterring China—concluded that Patriot interceptors and other key rounds had reached “dangerously low” numbers. A senior defense official told Politico that contingency thresholds for several munitions “could no longer be met” if the Ukraine pipeline continued unchanged.
White House Deputy Press Secretary Anna Kelly called the decision “an America-first choice” and insisted that “the strength of the United States Armed Forces remains unquestioned—just ask Iran.”
Kyiv received the news only days after Russia unleashed its largest air raid of the war—477 drones and decoys plus 60 missiles—forcing Ukrainian air-defense crews to ration Patriots and NASAMS interceptors. “It’s painful,” said Fedir Venislavskyi, a member of Ukraine’s security committee, noting an existing shortage of 155 mm shells on the Donetsk and Sumy fronts.
President Donald Trump has sought a negotiated end to the conflict since taking office in January, even as he keeps the option of selective weapons sales on the table. After meeting President Volodymyr Zelenskyy on the sidelines of last week’s NATO summit in The Hague, Trump acknowledged Ukraine’s plea for “anti-missile missiles” and said, “We’re going to see if we can make some available—they’re very hard to get.”
Pentagon planners say Army procurement targets for Patriot MSE interceptors have already been quadrupled, but industry analysts warn that refilling the magazine will take years, not months. Remaining Ukraine funds appropriated under the Biden administration are expected to expire this fall, and the new Republican-led Congress has yet to schedule a vote on additional Ukraine-specific aid.
Tuesday’s freeze is the third pause in U.S. lethal aid this year—after shorter interruptions in February and March—and comes with no formal policy change. In an email to Reuters, the Pentagon said it is “rigorously examining and adapting” its approach to balance support for Kyiv with readiness “for administration defense priorities,” a phrase widely read on Capitol Hill as shorthand for the Indo-Pacific.
For now, pallets of interceptors sit idle in Polish warehouses while Russian forces press their summer offensive. Whether the missiles eventually move east—or stay home to replenish U.S. stockpiles—will depend on how the Trump administration weighs Europe’s war against its broader “peace through strength” doctrine.
