"Let me introduce to you one interesting underwater experiment - building and using underwater inflatable habitat "Спрут" [sprut] ("Kraken"). First underwater installation was made in Jun 14 1967 on the Black Sea.
Later I will publish here some texts (with links), tanslated by google, and some photos from another resources.
I know Alexander Korolev, one of the builders, divers, and sciensists, who work with Спрут. Those times we discussed with him about first soviet rebreather Epron (first and than 2-5 editions).
You can find some photos on the his FB page here
