Russian monitor Perun

Russian Uragan-class monitor

Perun (Russian: Перун) was an Uragan-class monitor built for the Imperial Russian Navy in the mid-1860s. The design was based on the American Passaic-class monitor, but was modified to suit Russian engines, guns and construction techniques. Spending her entire career with the Baltic Fleet, the ship was only active when the Gulf of Finland was not frozen, but very little is known about her service. Perun was struck from the Navy List in 1900 and became a pilot ship. Renamed Lotsiia (Pilot) in 1915, the ship was damaged during the Kronstadt rebellion of 1921 and laid up afterwards. She was run aground by a flood three years later and then her wreck was scrapped.

Description

Perun was 201 feet (61.3 m) long overall, with a beam of 46 feet (14.0 m) and a draft of 10.16–10.84 feet (3.1–3.3 m). She displaced 1,500–1,600 long tons (1,524–1,626 t), and her crew numbered 8 officers and 88 enlisted men in 1865. They numbered 10 officers and 100 crewmen 12 years later.[2]

The ship was fitted with a two-cylinder, horizontal direct-acting steam engine[2] built by Carr and MacPherson of Saint Petersburg. It drove a single propeller[3] using steam that was provided by two rectangular boilers.[4] Specific information on the output of the ship's engine has not survived, but it ranged between 340–500 indicated horsepower (254–373 kW) for all the ships of this class. During Perun's sea trials on 16 August 1865, she reached a maximum speed of 6.75 knots (12.50 km/h; 7.77 mph). She carried a maximum of 190 long tons (193 t) of coal, which gave her a theoretical endurance of 1,440 nmi (2,670 km; 1,660 mi) at 6 knots (11 km/h; 6.9 mph).[5]

Perun was designed to be armed with a pair of nine-inch (229 mm) 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 fifteen-inch (380 mm) smoothbore muzzle-loading Rodman guns in 1867–68. The Rodman guns were replaced around 1876 with the originally intended nine-inch rifled guns.[6]

All of the wrought-iron armor that was used in the Uragan-class monitors was in 1-inch (25 mm) 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 42 inches (1.1 m) below the waterline. This armor was backed by a wooden beam that had a maximum thickness of 36 inches (914 mm). 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 7 feet (2.1 m) above the deck. Unlike their predecessors, the Uragans were built without deck armor to save weight.[7]

Career

Construction of the ship began on 7 September 1863 at the Semiannikov & Poletika Shipyard in Saint Petersburg. Perun was laid down on 15 December 1863 and she was launched on 30 June 1864. She entered service on 1 September 1865 and cost a total of 1,142,700 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 Latnik, made a port visit to Stockholm, Sweden in July–August 1865 while under the command of General Admiral Grand Duke Konstantin Nikolayevich.[8] She was present when the American warships Miantonomoh and Augusta visited Kronstadt in July–August 1866.[9]

Sometime after Perun was completed, an armored ring, 5 inches (127 mm) thick and 15 inches (381 mm) 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 1.75-inch (44 mm) 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.[10]

Little is known about the ship's career other than that she was laid up each winter when the Gulf of Finland froze. On 18 July 1875, she was accidentally rammed by the ironclad Admiral Chichagov, but only suffered minor damage. Perun 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. After she was stricken she was used as a pilot ship before being renamed Lotsiia (Pilot) in 1915. During the 1921 Kronstadt rebellion, the ship was struck by artillery fire. She was laid up after the resulting fire badly damaged her. During a flood on 23 September 1924, Lotsiia ran aground and was subsequently broken up for scrap.[11]
