Ironclad warships of the Imperial Russian Navy

Vitse-admiral Popov was a monitor built for the Imperial Russian Navy in the 1870s. It was one of the most unusual warships ever constructed, and still survives in popular naval myth as one of the worst warships ever built. The hull was circular to reduce draught while allowing the ship to carry much more armour and a heavier armament than other ships of the same size. Vitse-admiral Popov played a minor role in the Russo-Turkish War of 1877–78 and was reclassified as a coast-defence ironclad in 1892. The ship was decommissioned in 1903 and sold for scrap in 1911.

The Admiral Spiridov class were a pair of monitors built for the Imperial Russian Navy in the late 1860s. The sister ships were assigned to the Baltic Fleet upon completion and remained there for their entire careers. Aside from several accidental collisions and one grounding, their careers were uneventful. They were reclassified as coast-defense ironclads in 1892 before they became training ships in 1900. The Admiral Spiridovs were stricken from the Navy List in 1907; one ship became a stationary target and the other a coal-storage barge. Their ultimate fates are unknown.

The Charodeika class was a pair of monitors built for the Imperial Russian Navy in the late 1860s. They were designed by the British shipbuilder Charles Mitchell and built in Saint Petersburg. Both ships were assigned to the Baltic Fleet and had fairly uneventful careers mostly assigned to training units. Rusalka struck a rock in 1869 and had to be run aground lest she sink. They were reclassified as coast-defense ironclads in 1892 and Rusalka sank during a storm in the Gulf of Finland the next year with the loss of all hands. Her sister ship Charodeika continued in service until 1907 and was eventually scrapped in 1911–12. Rusalkas wreck was discovered in 2003 by an expedition sponsored by the Estonian Maritime Museum.

The Russian ironclad Petropavlovsk (Russian: Петропавловск) was a 22-gun armored frigate in the Imperial Russian Navy during the late 19th century. She was originally ordered as a 58-gun wooden frigate, but she was reordered as an ironclad while under construction and subsequently converted into one. 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.

The Pervenets-class ironclads were a group of three armored frigates built for the Imperial Russian Navy in the 1860s. The first ship was built in England because the Russian Empire lacked the ability to build its own ironclads, but the other two were built in Russia. All three ships differed from one another as the design evolved over time. None of the ships ever saw combat and only Kreml had an eventful career, sinking a wooden frigate in an collision in 1869 and sinking herself in 1885. She was refloated and returned to service. They were assigned to the Baltic Fleet upon completion and never left Russian waters. They served with the Gunnery Training Detachment for the bulk of their careers before being reduced to reserve in 1904. They were sold four years later and Pervenets and Ne Tron Menia were converted into coal barges. Pervenets survived World War 2 and was scrapped in the early 1960s, Ne Tron Menia was sunk during the war and scrapped around 1950, while Kremls fate after her sale is unknown

The Russian ironclad Kniaz Pozharsky (Russian: Князь Пожарский) was an iron-hulled armored frigate built for the Imperial Russian Navy during the 1860s. She was the first Russian armored ship to leave European waters when she cruised the Pacific Ocean in 1873–75. The ship did not participate in the Russo-Turkish War of 1877–78, and remained in the Baltic Sea until 1879–80, when she made another cruiser to the Pacific. Kniaz Pozharsky was assigned to the Baltic Fleet for the rest of her career. She mainly served as a training ship after her refit in 1885 until she was hulked in 1909 and probably scrapped in 1911.

The Uragan class (also known as the Bronenosetz class, Russian: броненосец, "armor carrier" or "warship") was a class of monitors built for the Baltic Fleet of the Imperial Russian Navy. The ships were built to the plans of the American Passaic-class monitors, a design that was tested on a smaller scale on USS Monitor. A total of 10 ships were constructed at five different shipyards in Saint Petersburg, all entering service in 1865. The ships were among the first ironclad warships in the Russian Navy.

Petr Velikiy (Russian: Пётр Великий – Peter the Great) was an ironclad turret ship built for the Imperial Russian Navy during the 1870s. Her engines and boilers were defective, but were not replaced until 1881. The ship made a cruise to the Mediterranean after they were installed, and before returning to the Baltic Fleet, where she remained for the rest of her career. She did not, like the rest of the Baltic Fleet, participate in the Russo-Turkish War of 1877–1878. Petr Veliky was deemed obsolete by the late 1890s, but she was not ordered to be converted into a gunnery training ship until 1903.

Novgorod (Russian: Новгород) was a monitor built for the Imperial Russian Navy in the 1870s. She was one of the most unusual warships ever constructed, and still survives in popular naval myth as one of the worst warships ever built. A more balanced assessment shows that she was relatively effective in her designed role as a coast-defence ship. The hull was circular to reduce draught while allowing the ship to carry much more armour and a heavier armament than other ships of the same size. Novgorod played a minor role in the Russo-Turkish War of 1877–78 and was reclassified as a coast-defence ironclad in 1892. The ship was decommissioned in 1903 and used as a storeship until she was sold for scrap in 1911.

The Russian ironclad Kreml (Russian: Кремль) was the third and last Pervenets-class broadside ironclad built for the Imperial Russian Navy during the mid-1860s. She joined the Baltic Fleet upon completion and accidentally sank a Russian frigate in 1869. The ship was assigned to the Gunnery Training Detachment in 1870 and was frequently rearmed. Kreml sank in shallow water after a storm in 1885; she was refloated and returned to service. The ship was placed in reserve in 1904 and disarmed the following year before being sold for scrap in 1908.
