Russian radars are of good build, but the material they use...
First, those links you show and text, is what we in the industry call for documents that we make to get people to believe it's worse than it is. for example those pictures are of equipment they have deliberately put under extreme condition, to force out that result. Heck I can show pictures like that too from Norway...
Classic problem in Norway and many other places, this vessel was repainted just 5 years before this picture a year later it sunk:

or if you park you'r boat, for some years, without maintaining it:

we have the same problem, trust me, it's not special in the tropic region, we go from extreme cold weather that destroy everything to hot and extreme wet, for example where I live, is among the wettest places in the world, we haven't had summer this year, one of the city here in Norway had just sat new record, with rain 300 days this year and we have only had 20 days with sun.... so yeah, biscuit.
When it come down to metal, it's all about what type of paint we use.
For example: the Norwegian frigate, when we received them from Spain, we had to repaint them, due to the paint could handle the climate we have in North, they started to rust and mold almost immediately they hit Norwegian water. But that is our problem, we did not specify that in the builder contract. But we did specify that the frigate must survive with minimum 300 tons of ice on deck!
all the other mold I see on that picture, come down to people haven't done their work, in maintaining and it haven't been given the proper treatment. I see that to often here at work, since I am an professional wood worker with documents, here at work we quit often bill the customer for not have given there furniture or stairs the proper treatment. a chair will not survive 40 years+ if no-one maintain it. leather for example should always be oiled every X-years. now on one of the picture there is an backrest for an chair, that is not leather, it fake leather, and it have obviously not been waxed, if it had, that mold have never happened.
But we all know how military work, they buy something new, they use it until it's destroyed, with minimum maintenance.... then trow it away.
heck we have the same problem in Norway, we have tanks, aircrafts ships that have to go into very long and expensive maintenance, due to people haven't maintained it at all
Colosseum, yes I know. you can move all this shit.... I'm done with him, he doesn't understand that it's the same problem in the entire problem. And that when you order a new equipment like a tank... you specified in the documents that it need to be protected against certain things.
Why are I bothered anyway...?
