F-35 ‘Jailbreakable’ Like iPhone? Concerns Rise Over US Control of Jet Software

The Hague, Netherlands – The Lockheed Martin F-35 Lightning II, a technologically advanced fighter jet costing approximately $80 million, may be vulnerable to a security flaw allowing it to be “jailbroken” like an iPhone, according to Dutch Defense Secretary Gijs Tuinman. The revelation, made during a recent podcast interview, raises questions about the long-term independence of European militaries operating the F-35 and their reliance on the United States for software maintenance and upgrades.

Tuinman’s comments, made on the Danish podcast “Boekestijn en De Wijk,” surfaced earlier this week and have quickly drawn attention from defense analysts and cybersecurity experts. He suggested that European armed forces could potentially maintain the F-35 fleet even without ongoing support from the United States. “The F-35 is truly a shared product,” Tuinman stated, as translated from Dutch. “The British make the Rolls-Royce engines, and the Americans simply need them too. And even if this mutual dependency doesn’t result in software updates, the F-35, in its current state, is still a better aircraft than other types of fighters.”

The core of Tuinman’s assertion lies in the possibility of circumventing the proprietary software controls implemented by Lockheed Martin. “If you still want to upgrade despite everything – I’m going to say something I should never say, but I will anyway – you can jailbreak an F-35 just like an iPhone,” he said. While Tuinman offered no specific details regarding how such a “jailbreak” might be achieved, the analogy to the well-known practice of bypassing security restrictions on Apple’s iPhone suggests a potential pathway to independent software modification.

The F-35 program, the most expensive weapons system in history, has long been a source of debate regarding its cost, complexity, and reliance on US-controlled software. Routine software updates are currently delivered to the entire F-35 fleet through Lockheed Martin’s Automatic Logistics Information System (ALIS), a system likened to iOS updates for iPhones. This centralized control gives the US government significant leverage over the operational capabilities of F-35s operated by allied nations.

The potential for the US to withhold software updates – perhaps in response to geopolitical disputes or trade disagreements – has been a growing concern for European governments. The possibility of being left with a fleet of technologically advanced, yet effectively crippled, aircraft has fueled discussions about achieving greater software independence. Tuinman’s comments indicate that at least one European defense official believes such independence may be attainable, even if through unconventional means.

Ken Munro, a cybersecurity expert with Pen Test Partners who has experience analyzing aircraft technology, noted that while he wasn’t familiar with the specifics of the F-35, Tuinman’s suggestion wasn’t entirely surprising. He cautioned, however, that successfully “jailbreaking” a fighter jet would be significantly more complex than modifying a smartphone. “Without physical access to a fighter jet, the chance of a jailbreak becoming public knowledge is highly unlikely,” Munro stated.

The implications of successfully jailbreaking the F-35 are far-reaching. It could allow European nations to develop and implement their own software modifications, potentially enhancing the aircraft’s capabilities or tailoring it to specific operational requirements. However, it also raises serious security concerns. Unauthorized software modifications could introduce vulnerabilities that could be exploited by adversaries, compromising the aircraft’s systems and potentially jeopardizing national security.

any attempt to circumvent Lockheed Martin’s software controls could lead to legal challenges and strain relations with the United States. Lockheed Martin has not yet publicly responded to Tuinman’s comments, referring inquiries to the US government, which has not issued a statement as of February 22, 2026. The potential for legal action and diplomatic repercussions adds another layer of complexity to the issue.

The debate over F-35 software independence comes at a time of increasing geopolitical uncertainty. Concerns about the reliability of US support for its allies, particularly in the wake of shifting political landscapes, have prompted European nations to explore ways to enhance their strategic autonomy. Tuinman’s remarks, while controversial, reflect a growing desire among some European policymakers to reduce their dependence on the United States for critical defense capabilities.

While the feasibility and security implications of “jailbreaking” the F-35 remain uncertain, Tuinman’s comments have sparked a crucial conversation about the future of European defense and the balance of power in the transatlantic relationship. The question of who controls the software – and the capabilities – of these advanced fighter jets will likely remain a central point of contention for years to come.
