Russian monitor Edinorog

Edinorog was {{convert|201|ft|m|1}} long overall, with a beam of {{convert|46|ft|m|1}} and a draft of {{convert|10.16|-|10.84|ft|m|1}}. She displaced {{convert|1500|-|1600|LT|t}}, and her crew numbered eight officers and 88 enlisted men in 1865. They numbered 10 officers and 100 crewmen in 1877.McLaughlin, p. 103

The ship was fitted with a two-cylinder, horizontal direct-acting steam engine built by the Baird Works of Saint Petersburg. It drove a single propellerMcLaughlin, pp. 106–07 using steam that was provided by two Morton rectangular boilers.Chesneau & Kolesnik, p. 175 Specific information on the output of the ship's engine has not survived, but it ranged between {{convert|340|-|500|ihp|0|lk=in}} for all the ships of this class. During Edinorog{{'}}s sea trials on 19 June 1865, she reached a maximum speed of {{convert|5.75|kn|lk=in}}, the second slowest ship in the class. The ship carried a maximum of {{convert|190|LT|t}} of coal, which gave her a theoretical endurance of {{convert|1440|nmi|lk=in}} at {{convert|6|kn}}.McLaughlin, p. 107

Edinorog was designed to be armed with a pair of {{convert|9|in|adj=on|0}} smoothbore muzzle-loading guns purchased from Krupp of Germany and rifled in Russia, but the rifling project was seriously delayed and the ship was completed with nine-inch smoothbores. These lacked the penetration power necessary to deal with ironclads and they were replaced by license-built {{convert|15|in|adj=on}} smoothbore muzzle-loading Rodman guns in 1867–68. The Rodman guns were replaced around 1876 with the originally intended nine-inch rifled guns.McLaughlin, pp. 104–05

All of the wrought-iron armor that was used in the Uragan-class monitors was in {{convert|1|in|0|adj=on}} plates, just as in the Passaic-class ships. The side of the ship was entirely covered with three to five layers of armor plates, of which the three innermost plates extended {{convert|42|in|m|1}} below the waterline. This armor was backed by a wooden beam that had a maximum thickness of {{convert|36|in|0}}. The gun turret was protected by eleven layers of armor and the pilothouse above it had eight layers of armor. Curved plates six layers thick protected the base of the funnel up to a height of {{convert|7|ft|m|1}} above the deck. Unlike their predecessors, the Uragans were built without deck armor to save weight, but Edinorog was modified for the addition of {{convert|0.5|in|1|adj=on}} armor plates after completion, but it is unknown if they were ever fitted. They were, however, manufactured and then placed in storage.McLaughlin, pp. 105–06

Construction of the ship began on 13 June 1863 by S. G. Kudriavtsev at the state-owned Galeryni Island Shipyard in Saint Petersburg. Edinorog was laid down on 1 December 1863 and she was launched on 2 June 1864. She entered service on 27 July 1865 and cost a total of 1,141,800 rubles, almost double her contract cost of 600,000 rubles. The ship was assigned to the Baltic Fleet upon completion and she, and all of her sister ships except {{ship|Russian monitor|Latnik||2}}, made a port visit to Stockholm, Sweden in July–August 1865 while under the command of General Admiral Grand Duke Konstantin Nikolayevich.McLaughlin, pp. 100, 104, 109

Sometime after Edinorog was completed, an armored ring, {{convert|5|in|0}} thick and {{convert|15|in|0}} tall, was fitted around the base of the turret to prevent splinters from jamming it. Later, an armored, outward-curving bulwark was fitted around the top of the turret to protect any crewmen there. Three sponsons were later added, probably during the 1870s, to the upper portion of the turret. Each sponson, one above the gun ports and one on each side of the turret, mounted a light gun, probably a {{convert|1.75|in|adj=on}} Engstrem gun, for defense against torpedo boats. A fourth gun was mounted on a platform aft of the funnel when a hurricane deck was built between the funnel and the turret, also probably during the 1870s.McLaughlin, p. 108

Little is known about the ship's career other than that she was laid up each winter when the Gulf of Finland froze. Edinorog was reclassified as a coast-defense ironclad on 13 February 1892 and turned over to the Port of Kronstadt for disposal on 6 July 1900, although she was not stricken until 17 August. The ship was converted into a mine storage hulk in 1912 and renamed Blokshiv No. 4 on 10 July of that year. She was abandoned by the Soviets in Helsingfors (Helsinki) when they were forced to withdraw from Finland in April 1918 according to the terms of the Treaty of Brest-Litovsk, but she was later returned by the Finns. The ship was redesignated as Blokshiv No. 2 on 1 January 1932 and survived World War II to be renamed BSh-2 on 16 May 1949. She was stricken on 27 June 1957 and turned over to the Kronstadt Yacht Club. Her ultimate fate is unknown.McLaughlin, pp. 109–10
