Netherlands says it can hack F-35 code - Defense Express

While the possibility of gaining extended access to the F-35’s software exists in theory, its practical implementation remains uncertain.

The idea is that such access would allow operators to independently maintain the aircraft’s combat readiness, integrate new weapons, and adapt systems without critical reliance on the US.

A Dutch defense official hinted at this, comparing the process to jailbreaking a smartphone - gaining full access to the system. At the same time, he acknowledged that he could not disclose details and that there is no technical evidence confirming the existence of such a mechanism.

The primary dependency for F-35 operators is not only the software code but also the Mission Data Files (MDFs), which control the aircraft’s sensors, combat algorithms, and stealth capabilities.

These files are generated by a specialized U.S. Air Force unit based on data from the global F-35 fleet, effectively leaving Washington in control of the aircraft’s combat capabilities.

Moreover, the level of technological access varies among program partners. The UK has the broadest access due to the deep involvement of its defense industry in aircraft development.

Israel also operates a modified version with its own systems, and extended access has at times been offered to Japan. The Netherlands, however, holds a limited status in the program, raising doubts about its ability to independently modify the aircraft’s software architecture.

Even with hypothetical access to the software, F-35 operators remain dependent on the United States because of US control over key components, logistics, and maintenance systems.

European companies primarily handle final assembly, whereas critical technologies and long-term support remain under US oversight. As a result, fully independent operation of the F-35 without US involvement remains highly unlikely, even if some technical restrictions could theoretically be bypassed.

American aircraft in Ukraine: latest updates

Meanwhile, Ukraine has formed an F-16 squadron comprising Ukrainian, American, and Dutch pilots. They help defend the skies against Russian missiles and drones.

Back in 2023, the Ukrainian Air Force suggested that, with the appropriate military occupational specialty, foreign nationals could serve as pilots or aviation engineering specialists. However, such service has never been officially confirmed.

Still, American aircraft are not expected to become the backbone of Ukraine’s air force. The primary combat jets are planned to be the Gripen and Rafale - two modern fighters that could together expand Ukraine’s air fleet by up to 250 aircraft.
