Dubna

The Dubna class (Project 160) is a series of Soviet-designed medium replenishment tankers built to support naval task groups at sea. These vessels are equipped to transfer liquid cargo such as fuel oil, diesel, and fresh water, as well as dry provisions to warships while underway. They play a critical role in extending the operational reach of naval fleets.

Designed in the Soviet Union, the Dubna-class tankers were constructed by the Rauma-Repola shipyard in Finland during the mid-1970s. A total of four vessels—Dubna, Pechenga, Irkut, and Vyazma—were completed and entered service with the Soviet Navy between 1974 and 1978. Throughout the Cold War and into the post-Soviet era, they provided vital logistical support to Northern and Pacific Fleet deployments. As of the 2020s, several units of this class remain active in the Russian Navy.
