I had watched it but I watched it again after your post.
First I want to give some info about the problem they have told in the video. First they have built the sonar but not the transducer. They wanted to buy it but it is not sold to them. This is a really big problem about a strategic equipment. Those transducers are specially made if you want to put them in a warship. They are huge in dimentions and they are not mass produced. They are produced on order with very small amount(3-4 may be less). This is a problem, a really big one. Then when you try to produce it locally they do not give the material.
Ok; this is a problem but what is that transducer? Those are equipment producing mechanical waves. You use piezoelectric materials to produce waves. Piezoelectric materials are the materials that deforms its shape when you apply electricity on them. So; you transform electrical waves into mechanical waves.(sound) This is reversable; when you apply mechanical force they produce electrical potential. Some old tech(and some new ones too) microphones and speakers work like that in small scale.(the same actually)
You can produce it, but they do not sell you the materials. So; you can not buy or scavenge or smuggle materials in large scale. (modern sonars use relatively high tech composite piezoelectric materials) In this case you can not produce it until you control all the production line from raw materials to end product.
The problem I was talking about has some different variables. For example resistants, capacitors, low tech integrated chips:
1) Produced by many countries, found in every market, easy to reach, easily scavengable
2) Easy to find in masses, produced in masses(like 500 million resistants/month in a facility)
3) Easy to find in civillian life, can be bought in masses, easy to carry, small, extremly cheap, easy to smuggle
Because of these even total dependency is not even a small problem. Even I can smuggle these. Dependency on raw and not processed PCB is the same. But if we are talking about RISC microprocessors used in military equipment it is all different. Not just the block of sale; you can integrate some code to break it or manipulate it. (All intel and amd processors have those, and you can not patch it because it is a process executed by hardware logis gates) Both electronic parts but capacitors and microprocessors have big differance because of things like that trojan-like behaviour and those 3 member list I have written.
You can send 500 people around the world and they can buy these in big numbers and they can carry these into the country from border with a donkey. We have some specialists in east of our country, send those fckers and they will even bring the factory piece by piece.(including some chinese workers)
If you rely on that, than you might end up increasing the prices of 5cent parts to 50c or if the greed is strong 100c, because if you have a controlled group of smugglers which they mostly are, they will keep the price up to milk it. Hell they might even work with the smugglers and restrain those who are trying to do it for the greater good.
It is better not to have liabilities and quality control with the small electronics no matter how simple is important.
At the bare minimum and this is only if we don't have such an establishment already, is that electronic parts, resistors etc are made in Turkiye with accordance to military requirements and a small production capacity, which we can expand if we need. Because one thing smuggled goods definitely does not guarantee, Quality Control.
