Sibiriyakov

The Sibiriyakov is a Project 862 (Yug-class) oceanographic research vessel operated by the Russian Navy. It is designed to conduct hydrographic surveys, oceanographic research, and underwater mapping in support of naval operations. The vessel is equipped with specialized sonar systems, scientific laboratories, and meteorological equipment.

Constructed at the Stocznia Północna shipyard in Gdańsk, Poland, the vessel was commissioned into the Soviet Navy in 1990 before transitioning to the Russian Navy. It has primarily served with the Baltic Fleet, conducting critical underwater research and intelligence-gathering missions in the Baltic and North Seas. In recent years, the ship has been noted for monitoring underwater infrastructure, including pipelines and cables. It remains active in service as a key auxiliary asset for Russian naval intelligence and hydrography.
