According to Dutch Defense Minister Gijs Tuinman, the software associated with the F-35 fighter jet may be susceptible to a form of ‘jailbreaking’ akin to practices used for both iPhones and video game consoles.
This assertion emerges amidst escalating diplomatic strains between the United States and its longstanding European allies.
Although it remains ambiguous whether this suggests a substantial cybersecurity flaw within the F-35 initiative, the remarks underscore a growing trepidation regarding Europe’s increasing dependence on American military technology.
The Notion of a ‘Jailbroken’ F-35
The confrontational stance of the Trump administration in international affairs has engendered grave concerns about Europe’s military resilience and autonomy. The F-35 system notably operates on a ‘just-in-time’ logistics framework, particularly concerning its maintenance and supply chain requirements.
With over ten European nations participating in the F-35 program, apprehensions regarding Trump’s tariff-laden diplomacy are rising.
“If, despite everything, you still wish to upgrade, I’ll state something I likely shouldn’t: you could jailbreak an F-35 much like an iPhone,” Gijs Tuinman remarked during his appearance on BNR Nieuwsradio’s “Boekestijn en de Wijk” podcast, as translated by The War Zone.
During the podcast, Tuinman refrained from divulging specific details about the jailbreaking procedure, nor did he clarify if this implication points to critical cybersecurity weaknesses within the F-35 aircraft.
In this context, ‘jailbreaking’ denotes a method of circumventing software limitations imposed on a hardware unit. Therefore, executing a jailbreak on an F-35 would enable a nation to modify the aircraft’s software without official sanction.
Concerns Over Europe’s Dependence on US Military Technologies
The F-35 program in the United States deliberately restricts the ability of international clients to alter the software on the jets. Up to now, only Israel is recognized to have successfully secured a deal permitting it to embed proprietary software into its fleet of F-35s.
According to The War Zone, nearly all operational F-35s receive updates through a cloud-based infrastructure initially termed the Autonomic Logistics Information System (ALIS). However, persistent challenges with this system prompted the creation of an alternative system known as the Operational Data Integrated Network (ODIN).
This cloud-based framework allows the F-35 initiative to upload mission data packages replete with sensitive intelligence, including enemy defense configurations. Consequently, a cybersecurity breach within the F-35 framework poses a dire threat, potentially jeopardizing the efficacy of ongoing and future operations.
Tuinman’s observations also bring to light the vulnerabilities associated with Europe’s reliance on U.S. military technologies.

His contemplation of the possibility of jailbreaking an F-35 implies that the Dutch military has critically evaluated the ramifications of being severed from U.S. support amid intensifying geopolitical frictions.
In recent months, notable European leaders have urged a transition to a “war economy.” For instance, French President Emmanuel Macron has publicly criticized his country’s defense sector, asserting that it must enhance its production speed and efficiency.
