>The risk to the supply chain is zero

Hypothetically, what would happen to a pcb board , 33x33cm in size, with the ground lines running around the edge of that board, when hit with a high power 900 MHz broadcast?

Aircraft go through many tests, including various electromagnetic interference tests. They should know exactly how it responds in such a scenario.

Of course, I was just illustrating with an elementary electromagnetism example that the risk isn't zero.

[mysterydip]

That's fair. There's always supply chain risk in more nefarious ways as well (rootkit/trojan in bios, etc)

That high power 900 MHz broadcast will travel half an inch, then get absorbed by the metal housing. Military electronics are shielded, both to protect them from EMP and to avoid detection by passive radar.

“Hypothetically speaking”. Heh. Good one.

On that note I don’t understand the willful cognitive dissonance around Chinese espionage. They’re a powerful state aggressively looking out for their own self interests just like all the others.
