In the beginning of the year
this German homemade submarine was noticed, and now this Russian one which is smaller has shown up.
According to
this site, it doesn't go very fast, only 4 knots. Says he goes from St. Petersburg to Helsinki, Finland and back without stopping.
This site with the same photos is in Russian if our translators care to have a go, if there is any more information.
But it would be pretty lonely wouldn't it?
Maybe that's the point.
