Trekh Ierarkhov was a Sultan Makhmud-class ship of the line built for the Imperial Russian Navy's Black Sea Fleet in the late 1830s. The ship had a relatively uneventful career, frequently being used as a troop transport including during campaigns in the Caucasus in the early 1840s to suppress unrest in the recently-conquered territory. She saw little activity after being laid up in 1845; considered for conversion to steam power in 1852, she was instead broken up in 1854 due to her poor condition and the lack of funds during the Crimean War.
