I’d assume there are those safeties and interlocks, you’d always want that, a thumbdrive with a program that disables it is just as easy and not a “bug” which is what I was getting at. But yeah, it’s unlikely most cargo ships would want that probably. I’m simply playing devils advocate because they do seem to have them, so how or why in the most reasonable sense is all I’m arguing.

My other thought behind it was also not necessarily that it is it’s own device/explosive but more so along the lines of “we will intentionally run this poorly to cause itself to self destruct.” Akin to running a car engine untuned and without a radiator then full throttling it.

Someone may have just developed a program that tells the engines to do that so you wouldn’t exactly need anything physically installed to have it work.

I always though the point was “This is secret/must not be given to the enemy” so destruction is a better option than having it seized
