Lockheed Martin's F-35 combat aircraft is a supersonic stealth "strike fighter." But this week the military news site TWZ reports that the fighter's "computer brain," including "its cloud-based components, could be cracked to accept third-party software updates, just like 'jailbreaking' a cellphone, according to the Dutch State Secretary for Defense."
TWZ notes that the Dutch defense secretary made the remarks during an episode of BNR Nieuwsradio's "Boekestijn en de Wijk" podcast, according to a machine translation:
Gijs Tuinman, who has been State Secretary for Defense in the Netherlands since 2024, does not appear to have offered any further details about what the jailbreaking process might entail. What, if any, cyber vulnerabilities this might indicate is also unclear. It is possible that he may have been speaking more notionally or figuratively about action that could be taken in the future, if necessary...
The ALIS/ODIN network is designed to handle much more than just software updates and logistical data. It is also the port used to upload mission data packages containing highly sensitive planning information, including details about enemy air defenses and other intelligence, onto F-35s before missions and to download intelligence and other data after a sortie. To date, Israel is the only country known to have successfully negotiated a deal giving it the right to install domestically-developed software onto its F-35Is, as well as otherwise operate its jets outside of the ALIS/ODIN network.
The comments "underscore larger issues surrounding the F-35 program, especially for foreign operators," the article points out. But at the same time F-35's have a sophisticated mission-planning data package. "So while jailbreaking F-35's onboard computers, as well as other aspects of the ALIS/ODIN network, may technically be feasible, there are immediate questions about the ability to independently recreate the critical mission planning and other support it provides. This is also just one aspect of what is necessary to keep the jets flying, let alone operationally relevant."
"TWZ previously explored many of these same issues in detail last year, amid a flurry of reports about the possibility that F-35s have some type of discreet 'kill switch' built in that U.S. authorities could use to remotely disable the jets. Rumors of this capability are not new and remain completely unsubstantiated."
At that time, we stressed that a 'kill switch' would not even be necessary to hobble F-35s in foreign service. At present, the jets are heavily dependent on U.S.-centric maintenance and logistics chains that are subject to American export controls and agreements with manufacturer Lockheed Martin. Just reliably sourcing spare parts has been a huge challenge for the U.S. military itself... F-35s would be quickly grounded without this sustainment support. [A cutoff in spare parts and support"would leave jailbroken jets quickly bricked on the ground," the article notes later.] Altogether, any kind of jailbreaking of the F-35's systems would come with a serious risk of legal action by Lockheed Martin and additional friction with the U.S. government.
