Moving Tug Boats in place for the Big Tow I see

IIRC, the Admiral Flota Sovetskogo Soyuza Kuznetsov doesn't go anywhere without an ocean-going tug, 'just in case'. It has been that way from almost the beginning. The Kuznetsov generally blow VERY black smoke, along with its complement of jets. Easier to spot at a distance.
