perfidious kill switch claims
While it’s technically true the F35 doesn’t have a kill switch the ability for USA / Lockheed to degrade the plane it might as well be.
For example every mission needs the expected flight plan, radar contacts, weapons stowed, terrain/weather, fuel load etc etc upload to Lockheeds severs processed then uploaded to the Jet to maximum is changes of mission success,
Based on the processed data the plane can optimise its sensor array radar suite and jamming abilities to the potential targets.
If for example Canada was attending to attack Russia planes and the Trump administration disagreed they could simply refuse to process the data which would leave the plane more vulnerable and unable to work as effectively.
They could turn off the jamming abilities as seen with Ukraine and its F16 or disallow the targeting computers to load Russia fighter jet and missiles profiles leaving the targeting computers to rely on generic profiles instead,
Not an off switch but effectively muzzling the plane from Rottweiler to Toy Dog
