Poland is forced to stop further contributions to the PURL program, through which NATO countries finance the purchase of American weapons for Ukraine. This was stated by Polish Prime Minister Donald Tusk, explaining the decision by a number of circumstances that limit Warsaw's ability to continue financing the program.

The statement by the head of the Polish government was distributed by the Chancellery of the Prime Minister of Poland.

This concerns the Prioritized Ukraine Requirements List (PURL) mechanism, which allows European states and other partners to pay for the supply of American weapons to the Ukrainian army.

Poland has previously participated in financing this initiative. In December 2025, Warsaw announced a contribution of $100 million to a joint package with Germany and Norway. The total value of the package was $500 million.

As reported by the Polish Ministry of Foreign Affairs, the funds were intended for the purchase of weapons and ammunition needed by Ukraine to counter Russian aggression.

The PURL mechanism provides that Ukraine identifies the most urgent needs in armament, after which the US and NATO agree on appropriate supply packages. Partner countries allocate funding, and the American side ensures the transfer of equipment.

The program is of particular importance for the supply of air defense systems, including interceptor missiles for Patriot systems, as well as other types of weapons that are difficult to replace with European counterparts.

In early November, Bloomberg reported that the US was preparing to ask NATO allies to increase funding for PURL. According to the agency, the shortfall in funds under already agreed weapons packages reached about $2 billion.

However, Poland's decision on further contributions does not automatically mean the cessation of American supplies to Ukraine or Warsaw's withdrawal from other forms of military support for Kyiv.

It is not yet specified whether the limitation of PURL funding is permanent or Poland will be able to resume contributions under changed circumstances. The verbatim formulation of the reasons cited by Tusk could not be independently confirmed.
