This passage was the end of a very long overhaul and operational deployment. She was last seen in Istanbul passing southbound on 25.4.2019. She exited the Black Sea to sail to the Admiralty Shipyard in St. Petersburg for an overhaul. Later since December 2020, she was stationed in the Med.

She is one of the six 636.3 class submarines commissioned for the Black Sea Fleet between 2014 and 2016.
