It’s a different time, probably normal civilian chips to hitch onto the massive industry that now exists. Kind of like how I’d guess the F-14 airframe was made of normal metal instead of something new they invented.
The radar and EWAR-related hardware, on the other hand, might not just be off the shelf.



Hmm. Before the end of the 19th century you’re going to run into non-standardised/completely bespoke parts problems. How are you on a lathe, or doing blacksmith work? Hot riveting was a separate trade which you wouldn’t have to do, at least.
I’m kinda obsessed with what I call technological bootstrapping, and so I have useful book knowledge about every step along the way. Doing it in practice is another thing, though; the locals are going to run circles around me unless I can invent stuff. (And even that rule aside, not starving or being “disturbed” while I work on whatever project is a thing)
So, I think I have to echo the “it’s not going great in 2025” answer.
