Russian Submarine Krasnodar Transited Southbound Trough Istanbul

Today improved Kilo class (Proj. 636.3) submarine of the Russian Black Sea Fleet, Krasnodar made an unexpected southbound passage through Bosphorus.

The submarine one of the six units built specially for the Black Sea Fleet has been deployed in the region since 7.8.2017. She has 6 533mm torpedo tubes and carries a combination of up to 18 torpedoes, SS-N-27 anti-ship, and Kalibr land attack missiles.

While a southbound passage of a Russian submarine is very rare, it is has happened before. Russian Kilo class (Proj. 877) submarine Alrosa suffered an engine fire in 2009 and had to go to the Baltic for extensive repairs. She did even take part in the NATO exercise Bold Monarch 2011. Yes, it was different times then.

The Montreux Convention regulates the passage of submarines. While the submarines of non-Black Sea nations are forbidden to pass through the Straits, the submarines of the Black Sea riparian States may pass under certain conditions

Article 12.

Black Sea Powers shall have the right to send through the Straits, for the purpose of rejoining their base, submarines constructed or purchased outside the Black Sea, provided that adequate notice of the laying down or purchase of such submarines shall have been given to Turkey. Submarines belonging to the said Powers shall also be entitled to pass through the Straits to be repaired in dockyards outside the Black Sea on condition that detailed information on the matter is given to Turkey. In either case, the said submarines must travel by day and on the surface and must pass through the Straits singly.

The provision in the convention is very clear. If Krasnodar exited the Black Sea for repairs then this passage does not break the rules of the convention. If the submarine, however, joins her 2 sisters all ready stationed in the Med since 2017 and conducts military operations, then this will be a clear breach of the Montreux Convention. We will know better in a few days.
