Altay-class oiler

The Altay class (Project 160) is a class of replenishment oiler built for the Soviet navy between 1967 and 1972.

Construction
The vessels were built for the USSR by the Finnish shipbuilding yard Rauma-Repola. Over 60 vessels of this type were built for Soviet service, most with the fishing fleet and merchant fleet. Only 6 vessels were ordered for service with the Soviet navy. Project 160 tankers can refuel one ship at a time from either side or over the stern.

Ships in class
There were 6 vessels in the class.

Yel'nya incident
In April 1993, while in reserve with the Black Sea Fleet at Sevastopol, the Yel'nya was taken over by Ukrainian dissidents. After a brief seizure, control was reestablished by the Russian Navy. The Yel'nya was later transferred to the Baltic Fleet.
