Something a little different for your Retro Saturday.
Атомный флагман (Atomic Flagship) is a 1959 Soviet documentary about the atomic-powered ice-breaker, Ленин (Lenin). The film runs about 21 minutes. It's narrated with an English-language voiceover.
According to Wikipedia, Lenin was “both the world's first nuclear-powered surface ship and the first nuclear-powered civilian vessel. Lenin entered operation in 1959 and worked clearing sea routes for cargo ships along Russia's northern coast. She was officially decommissioned in 1989. She was subsequently converted to a museum ship and is now permanently based at Murmansk.”
I don't think this quite qualifies as a propaganda film, but it has all the trappings. A great classical orchestra and sophisticated cinematography. It also would have made a great target for Mystery Science Theater 3000.
