I’m still trying to figure out what Ukraine can do with an S-300 system considering that it is RUSSIAN-Built, and therefore has to have a backdoor to allow the Russians to either disable it, or fly blind to it.
I’m trying to figure out why you think your comment has any merit.
Huh? Where do you dream up this stuff? Considering it was developed in 1979, there is no doubt there are any electronics in the system… much less GPS or internet since that technology did not exist.
The S300 was made long before “backdoors” were a thing.
The S-300 doesn’t contain enough computer logic to *have* a backdoor. It is a late-70s development; a late 1980s Casio calculator watch probably has more processing power.
