Pamyat Merkuriya was seriously damaged in days of Civil war, repaired in 1922-1923 with usage of the gears lifted from sister-ship Bogatyr. After repair speed did not exceed 19kts. In 1930-1931 she was converted to TS. Both turrets were removed (Single 130mm/55 shielded guns were fitted instead), and 4 side 130mm/55 gun were replaced by 76mm/30 Lender AA guns.
