From the story:
Support vessels included the logistics vessel Elbrus, medium sea tanker Kama, and rescue tug Nikolai Chiker, according to the Russian Navy.
They brought their own fuel, food, and ocean-going tugboat. Hoping, apparently, that only one ship breaks down. They didn't bring the Admiral Kuznetsov inasmuch as that piece of nautical scrap is still in Kola Bay being dismembered, probably best for everyone associated.
Thanks. I corrected myself in #5. It does pay to read the excerpts, doesn’t it?
