The author writes this as if heat seeking missles are new tech. They’re not. The designers of the F-35 developed it knowing they exist and made whatever tradeoffs they decided to make. That’s just engineering.
But the real question is: does the appearance of good, cheap IR sensors in combat mean that we civilians will finally be allowed to buy thermal IR cameras that don’t suck? Everything is limited to 20 Hz with potato resolution. The ITAR restriction is a joke at this point.
It has never been compute-intensive. Current hypersonic kinetic-intercept missiles use ancient MIPS R3000/4000 class CPUs.
The US and Israel didn't lose a single pilot over Iran after 15,000+ sorties which is saying something on their capabilities.
F-35 flying relatively low (somewhere <FL200) and in full burner according to the alleged video.
Getting hard facts is complicated by the fact that this DoD isn't necessarily going to reveal what happened, and the IRGC can't be trusted 100%.
* Rumored that some components like some of the "camera" sensors were sourced from Canada.
1) It's not the 1990s anymore, Counter-Countermeasure IR missile discrimination is pretty common on imported MANPADs and IR SAMs.
2) The F-35 has a insanely hot engine even when it's not afterburning. The F135 produces hotter inlet temperature than even the F-22's engine (F119) giving older IR seekers an easier target.
