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. ^[1]

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. ^[2]
