The most advanced microchip produced in East Germany was the '1-MBit chip' (https://en.wikipedia.org/wiki/U61000), but AFAIK this suffered from terrible yields and didn't really go into mass production.

Here in Brno they also made world class electron microscopes & some of the leading electron microscopy companies still come from Brno or at least operate there (Delong Instruments, FEI, Thermo Fisher, etc.).
Modern optics are absolutely out of the question, which is why their Orlan drones have been found with consumer cameras for their optics.
As well as more advanced Thales thermal imaging systems that were installed in combat vehicles (tanks, IFV). AFAIK they were produced in Russia under a license from Thales (a French company) till at least 2016. Thales was likely evading sanctions

Soyuz (as in both rocket and capsule) has had multiple failures over the last decade. The most recent was the coolant leak a few weeks ago that made the capsule unusable for a safe return to Earth.

Ah, ok. So the source is trustworthy and objective, not a war party telling whatever they have to tell to support their cause.
