As relations between the US and its NATO allies experience greater political strain, European nations are openly discussing plans on what to do if the Trump administration cuts off access to US military support. One of the key weapon systems of concern is the fifth generation F-35 fighter — the aircraft's tremendous capabilities come in large part from connection to the global mission planning and logistics planning software and historical data controlled by the US. TWZ explains:
It’s this mission planning data package that is a major factor to the F-35’s survivability. The ‘blue line’ (the aircraft’s route into an enemy area) that is projected by the system is based on the fusion of a huge number of factors, from enemy air defense bubbles to the stealth and electronic warfare capabilities of the aircraft, as well as onboard sensor and weapons employment envelopes and integrated tactics between F-35s and other assets. To say the least, it is one of the F-35’s most potent weapons.
The Dutch Defense Minister, Gijs Tuinman, is now openly discussing the possibility of "jailbreaking" the software, to ensure the system can still be operated even if cut off from the US networks and data. Even if the aircraft's software was "jailbroken", the aircraft's capabilities would be diminished without access to US mission planning systems and data, let alone other critical aspects like access to spare parts. As TWZ notes:
Without [access to data], the aircraft and its pilot are far less capable of maximizing their potential and, as a result, are more vulnerable to detection and being shot down.
However, the step could help mitigate risks for European operators if the once unthinkable happens.
