Bora (former MRK-27) is a Bora-class corvette of the Soviet Navy and later the Russian Navy.

Construction and career

MRK-27 was launched in 1987 at the A.M. Gorky Shipyard, Zelenodolsk and commissioned on 30 December 1989.

On 19 March 1992, he was renamed Bora. In 1997, she was assigned to the Black Sea Fleet.

The corvette was reported active during the Russo-Ukraine War, but as of mid-2024 had relocated to the eastern Black Sea from Crimea where both she, and her sister ship Samum, had been evidently considered too vulnerable to potential attack.
