The Boris Chilikin class is a series of fleet replenishment oilers built in 1970s for the Soviet Navy and currently in service with the Russian Navy. A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment at sea. As the Soviet Navy began to more regularly operate in large areas of the world's oceans and because of the emergence of the Kiev-class aircraft carriers, demand for large surface supply ships increased. In 1967, the TsKB "Baltsudoproyekt" (now Baltic Shipyard) received technical and tactical assignment for the design of Project 1559V sea oilers based on the civilian Project 1559 or Velikiy Oktyabr class. The main designers were S.N. Shumilov and Captain 2nd rank Yu. D. Makshanchikov.

The maximum length of the ship is 162,3 m, the maximum width 21,4 m and draft 9,3 m. When in standard load, the ship has displacement about 6,950 tons and 22,460 tons while fully loaded. Endurance of the ships is 90 days during which they can travel the distance about 22,000 km (12,000 nmi). The oilers of this class are equipped with a device for the transfer of goods in move by the traverse method. This allows carrying out cargo operations during significant sea waves. A wide range of transported goods (for example, bunker fuel - 8,250 tons, diesel - 2,050 tons, jet fuel - 1,000 tons, drinking water - 1,000 tons, boiler feedwater - 450 tons, lube oil - 250 tons, provisions - 220 tons) allows to rank the oilers of this class to the ships for providing of complex supply. Originally, the ships were armed with two 57-mm AK-725 guns with MR-103 Bars fire control system, but during later operations these defensive weapons were removed.

Replenishment Oiler Ivan Bubnov laid down at the Baltiysky Shipyard named after S. Ordzhonikidze, Leningrad (yard No.617), launched 20 April 1974, commissioned 19 July 1975 and was assigned to the Black Sea Fleet.

Now in service.
