Japanese F-35 in the Pacific, cue biggest counter-espionage ops since Cold War

This article feels disingenuous. They make it out like they Chinese or Russians are going to just stumble upon a nice, neat F-35, ready for inspection.

A good illustration of this is the investigation of jet airliner wreckage. If you read into the reports a little, you’ll quickly find examples where visually unrecognisable fragments are easily identifiable by experts and they can reverse engineer the deformities into useful data about the crash. Explosive disassembly is a relatively well understood process, from little things like explosive bolts to big things like controlled demolitions of buildings, we have a pretty decent idea how explosions affect things.

To effectively destroy something so that it’s of no use to an adversary is quite challenging, last I heard the recommended process for destroying sensitive computers/electronic equipment in the field is thermite charges, the sort used to render tanks inoperable. They basically turn a smallish stack of electronics into as close to a puddle of slag as they can. Doing similar to a useful fraction of an F-35 would be extremely challenging.

I'm sure some of the materials on the F-35 would be very difficult for other countries to make at scale, figuring out how to fabricate parts out of those unusual materials at tolerances required for low-observability would be really tricky. I'm sure there are machinists anywhere who could figure it out, but at that point we're talking about bespoke part production using 98th+ percentile operators. Although skilled labor is cheap is China and Russia, it's pretty untenable to use it to produce a knock-off that'll eventually hold an inferior Chinese/Russian engine.
