“The ships are making a planned transition from the Mediterranean to the Black Sea, where they will take part in naval exercises,” the defense department said.

It is noted that the crews of the ships "Korolev", "Minsk" and "Kaliningrad" are now in the Dardanelles.

At the same time, the ships "Pyotr Morgunov", "George the Victorious" and "Olenegorsky miner" will pass through the Black Sea straits over the next day.

Earlier in Sevastopol, the crews of the large landing ships "Orsk" and "Novocherkassk" of the Russian Black Sea Fleet held special exercises to load military equipment and personnel of the Marine Corps.
