U.S. gives Poland $4 billion loan for weapons purchases

The United States gave Poland a new $4 billion loan for weapons purchases, extending a financing line that now totals about $20 billion and underscoring Washington’s strategy on NATO’s eastern flank. The announcement came as Poland flew its first U.S.-made F-35s, tying the money directly to a broader push to harden the alliance’s front line against Russia.

Thomas DiNanno, the U.S. Under Secretary for Arms Control and International Security, made the announcement during the inaugural flight ceremony for the F-35 jets Poland bought from the United States. The setting carried political weight: Poland’s newest fighter aircraft were presented not as a standalone procurement, but as part of a deeper U.S.-backed modernization drive aimed at keeping Warsaw armed, interoperable and ready.

For Poland, the loan helps sustain an ambitious, multi-year military buildup that has made it one of Europe’s heaviest spenders on defense. The State Department says Poland has about $20 billion in active government-to-government sales cases with the United States under the Foreign Military Sales system, while roughly 10,000 U.S. personnel are on rotation in the country. Those figures show that the relationship is not limited to financing alone. It is a dense security partnership built around equipment, training, deployment and long-term planning.

The latest loan also fits a clear pattern. On July 25, 2025, the State Department announced a separate $4 billion Foreign Military Financing loan guarantee to Poland. In December 2024, it said total U.S. loans and loan guarantees to Poland had reached just over $11 billion in the previous two years. A May 2026 report to Congress said Poland had become the largest recipient of FMF support, with more than five separate loans and loan guarantees totaling $15 billion, including help for U.S.-made systems such as Patriot missiles. That record shows a sustained effort to help Warsaw finance high-end Western arms on terms it can manage.

Polish officials have cast the F-35 deliveries as a historic step in the transformation of the Polish Armed Forces after Russia’s full-scale invasion of Ukraine. The Ministry of National Defence said the first Polish F-35 was unveiled in the United States on August 28, 2024, and the first three aircraft arrived in Poland on May 22, 2026. The Defense Security Cooperation Agency also notified Congress on August 26, 2025, of a possible $1.85 billion sustainment package for the fleet.

The message from Washington is plain: financing Poland’s buildup is not simply aid, but burden-sharing, industrial support and deterrence policy rolled into one. On NATO’s eastern edge, the United States is helping make Poland the kind of front-line power the alliance wants in place if pressure from Moscow grows.
