The Lockheed Martin F-35 Lightning II, a cutting-edge fifth-generation stealth fighter, has come under intense global scrutiny as concerns grow over US influence on the defence capabilities of allied nations relying on the jet.

Portugal rethinks F-35 purchase

Portugal has decided to pause plans to replace its aging F-16 fleet with F-35s. Defence Minister Nuno Melo cited shifting geopolitical dynamics, particularly the US’s posture on NATO and military affairs, as a factor in the decision. The move reflects growing caution among nations weighing advanced defence acquisitions against geopolitical autonomy.

Canada reevaluates billion-dollar F-35 deal

Canada is similarly reassessing its commitment to buy 88 F-35s in a deal worth nearly C$19 billion. Defence Minister Bill Blair indicated that domestic assembly options and alternative procurement strategies are under consideration, driven by economic and strategic self-reliance concerns.

‘Kill Switch’ fears loom large

A central point of worry is the so-called “kill switch” controversy. Though no physical disabling mechanism exists, the F-35’s heavy dependence on US-controlled software, parts, and maintenance support effectively means Washington could limit the jets’ functionality. This raises alarms over operational sovereignty for countries operating the aircraft.

Push for European defence autonomy

These debates highlight the broader issue of European defence autonomy. Increasing reliance on US-made military platforms like the F-35 may expose vulnerabilities if political relations sour. Consequently, many European nations are exploring indigenous defence solutions to safeguard strategic independence.

Conclusion

The F-35 saga underscores the delicate trade-off nations face: acquiring superior military technology while retaining sovereign control over their defence infrastructure. Both Portugal and Canada’s recalibrations reflect a growing global trend toward securing autonomy amid shifting geopolitical tides.
