Kaliningradneft

The Kaliningradneft class (Project 1589) is a series of Soviet replenishment tankers designed to support naval and merchant fleets with fuel, fresh water, and dry provisions. These vessels were built in Finland for the Soviet Union to bolster its auxiliary fleet's global reach. They served as vital logistical support ships during the Cold War, enabling long-range deployments of the Soviet Navy.

Developed in the late 1960s, the lead ship of the class, Kaliningradneft, entered service with the Soviet Navy in the early 1970s. A total of several vessels were constructed by the Rauma-Repola shipyard in Finland under Soviet contract. Throughout their operational lifetimes, they provided replenishment-at-sea capabilities in the Atlantic, Indian, and Pacific Oceans. Following the collapse of the Soviet Union, some vessels were transferred to the Russian Navy, while others were sold for commercial use or scrapped.
