Tri Sviatitelia (, meaning the Three Holy Hierarchs) was a pre-dreadnought battleship built for the Imperial Russian Navy during the 1890s. She served with the Black Sea Fleet and was flagship of the forces pursuing the mutinous battleship in June 1905. During World War I the ship encountered the German battlecruiser (formally Yavuz Sultan Selim) twice, but never hit the German ship, nor was she damaged by her. From 1915 onward she was relegated to the coast bombardment role as she was the oldest battleship in the fleet. Tri Sviatitelia was refitting in Sevastopol when the February Revolution of 1917 began and she was never operational afterwards. Tri Sviatitelia was captured when the Germans took the city in May 1918 and was turned over to the Allies after the Armistice in November 1918. Her engines were destroyed in 1919 by the British when they withdrew from Sevastopol to prevent the advancing Bolsheviks from using her against the White Russians. She was abandoned when the Whites evacuated the Crimea in 1920 and was scrapped in 1923. Design Tri Sviatitelias design was based on an enlarged version of the Baltic Fleet battleship with some improvements in armour and armament. The ship was long at the waterline and long overall. She had a beam of and a draught of . She displaced , over more than her designed displacement of . Tri Sviatitelia was considerably larger than Navarin, being longer, wider and displacing more. She had a metacentric height of . Propulsion The ships had a pair of three-cylinder vertical triple-expansion steam engines built by the British firm of Humphreys & Tennant that had a total designed output of . Steam was provided to the engines by 14 cylindrical fire-tube boilers at a pressure of , which drove pair of four-bladed screw propellers. On sea trials, the powerplant produced a total of and a top speed of . She carried a maximum of of coal at full load that provided a range of at a speed of . Tri Sviatitelia had three dynamos with a total output of 305 kW, but these were too small and could not supply enough power to work all the electrical equipment simultaneously. Armament Her main armament consisted of four 40-calibre Obukhov Model 1895 guns mounted in hydraulically powered twin-gun turrets fore and aft. Each turret had a firing arc of 270°. The guns had a firing interval
