Nah, please break down, drift onto the British coast and end up with the boat and crew interned until the end of the war.

There's the irony that the Germans' use of "high tech" equipment was a result of the dire situation... 9 time out of 10 the allies had something directly comparable but took the extra year to deliver it debugged and on mass rather than bug-riddled and in penny-packets...

Thr oxidiser is already built into the propellant. So major thing would be working out how to keep bits of the mechanism lubricated and not vaccum welding to each other.

That said, you're correct about the death tolls from allied firebombing of Japanese cities.

German internal reports, post-wat demographic studies and other cases of firestorms in European cities strongly suggests the death toll at Dresden was 20-30000, claims of 100000+can all be traced back to Nazi propaganda or Holocaust denier David Irving...

Optionally crewed rather than true uncrewed I suspect...

Run a minimal crew during development and maybe once in service for handling trickier operations (replenishment, docking).

Given iron casting wasn't a thing in Europe at the time and given the difficulties inherent in forging large chunks of iron pre-indusrial age tech you'd have to think irons rams were either not a thing or only practical for the smallest ships...

Of cause, there's a "lamer" but more realistic option of having a containerized fab you can setup on any convenient islands sitting aboard one of the amphibs...

Something like Minimal Fab setup might allow some ability to minimize the clean room issue (put the silicon in sealed, clean containers instead of a true clean room...). Thus far still rather old node size but...

@unavaleable.bsky.social has the excuse that DVTL is post-Taiwan war so the edge case of a chip shortage not far off total cutoff might have happened. But yeah, seems a bit of a long shot in real life.

Oh, there's certainly problems but given the size of the apparatus needed it's much more in the doable rather than totally insane range...

(Probably not massive scale until some years post-war but likely there for high value applications like code breaking, C3I, CNC machines, etc. within a year or two)

Beyond that, for scaling up downtime production there's been enough nerds-in-sheds doing roughly 1970s level optical lithography that I'd think 1970s-1990s tech is *probably* doable on a useful but small scale based on the knowhow the ISOTees would have.

14.07.2025 04:33 β€” πŸ‘ 6    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Electron beam lithography might be a reasonable go to there. Problem is much slower throughput than the various forms of optical lithography... But if it's for small volumes of high value (e.g. avionics) electronics that's probably okay.
