The Russian ironclad Petropavlovsk (Russian: Петропавловск) was ordered as a 58-gun wooden frigate by the Imperial Russian Navy in the early 1860s, but was converted while under construction into a 22-gun armored frigate. She served as the flagship of the Baltic Fleet during the 1860s and 1870s. The ship was decommissioned in 1885, but was not sold for scrap until 1892.
Petropavlovsk was 300 feet (91.4 m) long between perpendiculars, with a beam of 50 feet 4 inches (15.3 m) and a draft of 22 feet 2 inches (6.8 m) (forward) and 24 feet (7.3 m) (aft). She displaced 6,040 long tons (6,140 t) and was fitted with a blunt iron ram at her bow.Petropavlovsk was considered to be seaworthy; her total crew numbered 680 officers and enlisted men.
The ship was fitted with a horizontal return-connecting-rod steam engine built by the Baird Works of Saint Petersburg. It drove a single four-bladed propeller using steam that was provided by an unknown number of rectangular boilers. During the ship's sea trials, the engine produced a total of 2,805 indicated horsepower (2,092 kW) and gave the ship a maximum speed of 11.8 knots (21.9 km/h; 13.6 mph). The ship carried a maximum of 375 long tons (381 t) of coal, but her endurance is unknown. She was ship rigged with three masts.
