Give it to me straight - has an F-35 ever been shot down in combat?
I am aware there have historically been some accidental losses during training and crash landings during peacetime, but Iran claims 4 F35s have been downed so far in the past month and Israel says 0. There's not a great deal of evidence publicly available either way.
I'm aware it's technically feasible to get a lock on with heat seeking missiles but I am unsure if they are able to penetrate its countermeasures and stealth technology.
