I don't doubt that Russia is swimming in corruption and that it makes a lot of things more difficult. But to say that they're incapable of a major engineering project, even if Putin takes a personal interest? I think you'll need to justify that.
Well if you are aware of a major successful project bring an example. It would be hard to argue that Putin is not personally interested in any of the major military projects yet from Armata to fighter jets that even long term customers like India are abandoning due to horrible quality does not look like his personal interest helps much.
