Black Sea diesel-electric submarine fleet "Krasnodar" project 636.3 (code "Varshavyanka") will be scheduled for repair immediately after completion of tasks as part of a permanent group of the Russian Navy in the Mediterranean Sea. This was reported by TASS with reference to a source in the shipbuilding industry.
According to the source, the submarine will go for repair in April this year, without going to the main base of the Black Sea Fleet - Sevastopol, immediately heading for one of the Baltic enterprises. Most likely, Krasnodar will undergo scheduled repairs at the Kronstadt Marine Plant, where currently the same type of submarine Stary Oskol Black Sea Fleet, which arrived directly to the Baltic from the Mediterranean, is undergoing scheduled repairs. It is estimated that Krasnodar will be repaired immediately after Stary Oskol.
Last May, it was reported that the Stary Oskol and Krasnodar diesel-electric submarines will undergo scheduled repairs at the end of 2020. In October 2019, the media reported that the repair will be carried out at enterprises in the north-west of Russia.
