Summary
European nations refute claims that the U.S. has a “kill switch” for F-35 fighter jets, despite concerns raised after Trump suspended military aid and intelligence support to Ukraine.
While no evidence confirms such a switch, experts warn the U.S. could limit access to crucial software updates.
Belgium and Switzerland assert their F-35s remain autonomous but acknowledge reliance on U.S. data systems.
Set to receive 35 F-35s in 2026, some German politicians are questioning whether the purchase should have been made amid these concerns.
Having an actual functional f-35 to train against and have for testing countermeasures against would be very helpful though.
