Russian Federation Navy employs a wide variety of auxiliary ships, such as tankers, colliers, ship tenders, seaplane tenders, and a floating crane.

Of the Fleet Oiler design below, RF Navy acquired 4 in 1924, 2 in 1925, and 2 in 1934, for a total of 8. Four Betelgeuse class oilers remain in service. These ships have a combined capacity to transport 102,000 tons of oil.
