Aquanauts (Russian: Акванавты, romanized: Akvanavty) is a 1980 Soviet science fiction film directed by Igor Vosnesensky, based on the story of the same name by Sergei Pavlov.

[2][3] In the Indian Ocean the Deuterium 1010 station for the extraction of heavy water is located - fuel for nuclear power plants that provide energy to the west coast.

Once the serving vessel "King Viking Sky" picks up a surfaced rescue mesoscaphe with only one aquanaut, Jacques Dumont, who suffers a severe nervous breakdown; the second, Vilem Pasic, stayed at the bottom and, most likely, died.

The third hydrocombist of the same expedition, Sven Ball, and Igor Sobolev from the research vessel Taimyr, go down where they encounter a strange intelligent giant oceanic manta ray.

The final assembly and finishing took place in the port, where the decoration was loaded onto the Skif crane, which delivered the construction to Maly Atlesh Bay selected as the main film set.
