Poland will receive a new $4 billion loan from the United States under the Foreign Military Financing (FMF) program. This will be the country's fifth such loan in the past two years.
In total, Poland has recently secured $15.08 billion in military loans. According to Defense24, the new funds will be used to upgrade its F-16C/D Block 52+ fighter jets, as well as to purchase AH-64E Apache helicopters and Patriot air defense systems.

The U.S. has stated its interest in continuing cooperation in this area. The F-16 upgrades will include new AN/APG-83 SABR AESA radars, mission computers, data fusion systems, electronic warfare systems with updated databases, modern weapon systems, and other improvements.
Previously, after the announcement of the new U.S. defense budget, there were concerns in Poland that it might no longer be able to access FMF loans for new weapons purchases — essentially jeopardizing large defense contracts with American companies.

As an alternative, the European Security Action for Europe (SAFE) program was proposed, allowing countries to borrow funds to purchase European-made weapons. Poland even created a list of qualifying domestically produced equipment under the program.
For example, the Czech Republic plans to use SAFE funding to acquire Leopard 2A8 main battle tanks. Even Ukraine has expressed interest in such funding to address urgent needs in UAVs, missiles, and ammunition.

Now it's clear that Poland does not have to give up on U.S. weapons while having an alternative path for procuring European equivalents. This allows Warsaw to choose the better option and cover a broader range of defense needs.
Of course, the loans will eventually need to be repaid —but given their favorable terms, they allow Poland to strengthen its defense now and spread the financial burden over time. It's not a perfect solution, but it's a practical and available tool.
