Name That Tune: Can anyone link me to some classical music with a soviet Russian feel to it?

I’m trying to find a piece of classical music I found on youtube once, and I was wondering if anyone can help.

Basically it’s an orchestral piece of music with some humming vocals in it. The piece reminds me of soviet Russia, it has a very cold war kind of vibe to it.

I know that is not a lot to go on, but maybe it’s enough. If you are still having trouble picturing what I mean, try and imagine what kind of music you would hear in a submarine war movie in a dramatic scene when the Russians are going to sea and getting ready for battle.

Thanks.
