This glorious monstrosity was the Yakovlev design bureau's VVP-6 concept. This would have been a gigantic, VTOL SAM platform armed with six (!) S-75 Dvina missiles. Radar equipment for guiding the missiles and reloads would be stored in the fuselage. Considering that each missile is about ten meters long, the entire aircraft must have been about fifty meters long, or a bit longer than a B-52.
Sadly, the designers ran out of cocaine before their dream could be realized.
How serious were the commies about building a helicarrier? I don't know, but it does at least appear to have been a real design exercise. It's in this book.
