Portugal is reconsidering its plans to replace its aging U.S.-made F-16 fighter jets with modern F-35s, citing concerns over the geopolitical uncertainty under Donald Trump. This hesitation marks one of the first instances where the U.S. president’s policies may jeopardize a major arms deal.
The Portuguese Air Force has recommended purchasing Lockheed Martin F-35s, but outgoing Defense Minister Nuno Melo signaled caution in an interview with Público.
"We cannot ignore the geopolitical environment in our choices. The recent position of the United States, in the context of NATO ... must make us think about the best options, because the predictability of our allies is a greater asset to take into account."
Following Melo’s remarks, the Defense Ministry issued a statement to POLITICO, clarifying that the F-35 has not been ruled out but that Lisbon is evaluating multiple factors in its decision. These include:
Portugal’s hesitation reflects broader European concerns over Trump’s NATO stance and foreign policy shifts. The fear is that the U.S. could block access to vital software updates and spare parts, rendering the F-35 fleet less reliable in the long term.
"The world has changed ... and this ally of ours ... could bring limitations to use, maintenance, components, and everything that has to do with ensuring that aircraft will be operational in all types of scenarios," Melo warned.
He also indicated that European-made fighter jets could become a more viable alternative.
A Lockheed Martin spokesperson reaffirmed the company’s commitment to working with Portugal, calling the F-35 “the most advanced, survivable, and connected fighter aircraft in the world.” However, the company deferred questions about foreign military sales to the U.S. government.
Meanwhile, Dutch Defense Minister Ruben Brekelmans confirmed that the Netherlands will proceed with its F-35 contract, signaling that some NATO allies remain committed to the jet.
Portugal, however, has yet to sign a deal, and its final decision remains uncertain as it weighs Trump’s unpredictability and the future of U.S. military commitments.
