Germany's Hesitation on F-35 Purchase: Concerns Over US Control
Germany is reconsidering its $6.9 billion deal to purchase F-35 jets from the United States amid fears that these advanced aircraft could be rendered inoperable by a remote “kill switch” controlled by Washington. This development raises significant questions about the future of Germany's defense relationship with the US, particularly under the potential leadership of Donald Trump.

Recent reports have intensified scrutiny over the US's ability to disable military aircraft remotely, especially following instances where American-supplied F-16s in Ukraine reportedly stopped functioning. While this was attributed to issues with radar systems rather than intentional shutdowns, concerns remain about the implications for Germany’s planned acquisition of 35 F-35 jets.
The Kill Switch Controversy
The head of communications at Hensoldt, a prominent German arms company, confirmed that the notion of a kill switch is no longer just speculation. This revelation has sparked serious concerns within Berlin about the reliability and sovereignty of its military assets if they are dependent on American technology. Wolfgang Isinger, former chairman of the Munich Security Conference, cautioned that if Germany fears that the US could treat its F-35s similarly to how it allegedly handled the F-16s in Ukraine, the possibility of canceling the contract could be on the table.
Europe's Dependence on US Defense Technology
This situation reflects a broader unease about Europe’s increasing dependence on American arms. Data from the Stockholm International Peace Research Institute indicates that between 2019 and 2023, 55% of European arms imports came from the US, a notable rise from 35% in the previous five years. Such reliance exposes Europe to potential fluctuations in US foreign policy, especially regarding defense agreements.
Germany's Strategic Shift
In light of these concerns, German Chancellor-in-waiting, Friedrich Merz, has expressed an interest in discussing nuclear capabilities with France and Britain. His remarks emphasize the need for Europe to bolster its defense unity, particularly in nuclear deterrence. This shift comes as Trump has voiced the opinion that nuclear weapons pose a greater threat to humanity than climate change, warning that a nuclear conflict could arise at any moment.
Conclusion
As Germany navigates these complex defense considerations, the future of its F-35 purchase hangs in the balance. The country's apprehensions about American control over its military assets underscore a critical moment in European defense strategy, calling for a reevaluation of dependency on US technology and fostering independent security measures. The evolving geopolitical landscape will likely influence not just Germany's defense posture but also its broader relationships within Europe and with the United States.
