Certainly not a superpower by these metrics. However, Russia does possess a vast number of WMDs which still puts it superpower category.
There's no use-case for it in the modern world, except the threat of using it.
Not that any of this matters if our threat model includes an enemy who doesn't care if they get annihilated in the reprisal.
Disclaimer: I don't know about any of these things and they are just guesses.
