Netherlands Signals Readiness to ‘Go It Alone’ on F-35 Software if U.S. Blocks Updates

Aviation News – The Netherlands is prepared to bypass potential U.S. restrictions on F-35 software updates, with outgoing State Secretary of Defence Gijs Tuinman stating the country would “crack the code” and develop its own updates to keep the fighter fully operational and European-controlled.

The remarks come as European governments reassess their reliance on American-controlled mission software and logistics systems tied to the fifth-generation jet. Tuinman, speaking as he prepares to leave office, said the Netherlands would not accept any scenario in which access to critical upgrades or operational capabilities could be curtailed, stressing that national sovereignty and readiness must come first. The statement reflects broader debate within Europe about strategic autonomy in defense technology and supply chains.

At the heart of the issue is the aircraft’s highly integrated software architecture, which governs everything from mission planning and sensor fusion to weapons employment and maintenance diagnostics. Without timely updates, performance, security, and interoperability could degrade. Developing independent update capabilities would allow Dutch engineers to maintain operational control, adapt systems to European standards, and reduce vulnerability to political or export constraints.

“We cannot allow our armed forces to depend on decisions taken elsewhere,” Tuinman said, adding that the Netherlands is ready to ensure the F-35 remains fully deployable “with or without external software support.”

If pursued, the move could accelerate European collaboration on sovereign defense software and deepen cooperation among regional air forces operating the same platform. It may also prompt discussions with industry partners about shared maintenance, coding expertise, and secure update pipelines.
For now, the Netherlands continues to operate and expand its F-35 fleet while keeping contingency plans in place. The message from The Hague is clear: operational independence is becoming as critical as the aircraft itself, and Europe intends to safeguard both.
