We ordered a bunch of subs from France, using a nuclear design as the base, but our government had them rip out the nuclear reactors from the design and stuff diesel engines in their place instead.
Then they walked away from that agreement entirely and joined up with the US and UK instead.
Edit: Oh, and the subs we’re now buying from the US, we’re getting the US to maintain them because we’ve got no capability to do so here.
To me it’s the tech equivalent of painting yourself into a corner, sure it works at the moment but what are the hidden costs of sticking on a dead end technology? What’s the upgrade path from a C64, a C128? What happens if a chip on the circuitboard fails, or the power supply? Can’t exactly order a new one, they stopped making them over 30 years ago and the company has been defunct for basically the same amount of time.
I wish I could remember more details, but I remember years ago reading about a company that had a core product that depended on an old 286 era laptop with a special software/hardware combo for maintenance, and all I could think of was that a single accidental bump of a table was all it’d take to shut down that product for months until they could find the exact replacement.
