Just guessing, but it looks as if the Admiral Kuznetsov is running on Number 6 oil...
Yeah she is really belching the black smoke. Has Trabant two stroke engines running it?
Some of the Putinistas on FR were earlier suggesting that the recent refit of the Admiral Kuznetsov included the installation of a nuclear power plant. Laughable.
From what I understand, the Rooskie navy is not very modern and requires a lot of continual maintenance just to keep their vessels operating...they would have a lot of trouble in combat.
