Fun fact, military CPUs value reliability and hardiness more than raw computational power. Making them domestically is a lot easier than say, designing and manufacturing computer or mobile phone chips. I don’t see this as a big hurdle for the Indian defense industry.

Not exactly. Military CPUs are easy to design, but manufacturing is hard. You still need the components for vlsi. The question is, did they simply bought those components or do they have complete indigenous supply chain.

Manufacturing chips, military or commercial, is huge hurdle. Yes, one less than the others. But still a huge hurdle.

Russia is able to make the chips themselves without having a domestic silicon industry. I think you overstate the difficulty.

No. Russia has been making military CPUs from very beginning. One the capability is achieved, the countries outsource those thing for commercial reason. But fabrication is still tricky. For example,

For VLSI, you will still need basic components very few countries can produce.
For example, you can start with simple component as capacitors

If you have the components then it's easy to fabricate military grade cpus. That's the tricky "if"

I can't tell but being the equivalent of 2000s to early 2010s tech, it is more likely using wholely imported equipment.

My guess exactly.
CPU design has evolved with times but the CPUs & sockets used in 1970 isn't as same as 2000 & later. The methods & fabrication equipment are far far more sophisticated. If India has complete indigenous chain for military grade CPUs, i would say Europe , Russia & China should bury their heads in sands, Lol

China and Europe do have indigenous design and fab including fab equipment. While most of China's is also either wholely imported equipment and ones developed based on the principles used e.g. lithography, at least China has had a long time of self dependence even in chip fab.

China's level is now also almost caught up with the absolute leading edge and with the new attention and investment into the field, would only be accelerating this catch up. China's heavily invested and testing alternative technologies based on completely different principles as opposed to remaining with the semiconductor train. Will see in years/decades time.
