Russian battleship Andrei Pervozvanny

Andrei Pervozvanny (Андрей Первозванный—St Andrew the First-Called) was a Andrei Pervozvanny-class battleship predreadnought battleship built for the Imperial Russian Navy during the mid-1900s. The ship's construction was seriously extended by design changes as a result of the Russo-Japanese War and labor unrest after the 1905 Revolution, and she took nearly six years to build. Andrei Pervozvanny was not very active during World War I and her bored sailors joined the general mutiny of the Baltic Fleet in early 1917. She was used by the Bolsheviks to bombard the rebellious garrison of Fort Krasnaya Gorka during the  Russian Civil War in 1919 and was torpedoed by British Coastal Motor Boats shortly afterwards, as part of the allied intervention in the Russian Civil War. The ship was never fully repaired and was scrapped in 1923.

Description
Andrei Pervozvanny was 454 ft long at the waterline and 460 ft long overall. She had a beam of 80 ft and a draft of 27 ft. She displaced 18580 LT at deep load. Her hull was subdivided by 17 transverse watertight bulkheads and the engine rooms were divided by a centerline longitudinal bulkhead. She had a double bottom and a metacentric height of 4 ft. The ship's crew consisted of 31 officers and 924 crewmen.

Andrei Pervozvanny had two 4-cylinder vertical triple-expansion steam engines with a total designed output of 17600 ihp. Twenty-five Belleville water-tube boilers provided steam to the engines at a working pressure of 285 psi. On sea trials, the engines produced 17635 ihp and a top speed of 18.5 knots. She carried a normal load of 800 LT of coal that provided a range of 1300 nmi at a speed of 12 kn and a maximum load of 1500 LT that gave 2400 nmi at the same speed.

The main armament consisted of two pairs of 12 in Model 1895 40-caliber guns mounted in twin-gun turrets fore and aft. These guns had a maximum elevation of 35° and could depress to -5°. Eighty rounds per gun were carried and they could fire one round per minute. Eight of the fourteen 8 in Model 1905 45-caliber guns were mounted in four twin-gun turret at the corners of the superstructure while six were mounted in casemates in the superstructure. For defense against torpedo boats, Andrei Pervozvanny carried twelve 120 mm guns mounted in casemates above the 8-inch guns in the superstructure. Two underwater 450 mm torpedo tubes were mounted, one on each side, and they were provided with six spare torpedoes.

Based on the Russian experience at the Battle of Tsushima, the sides of the ship's hull were completely protected by Krupp cemented armor. The main waterline belt had a maximum thickness of 8.5 in and the upper belt was 5 in at its thickest. The sides of the main gun turrets were 8 in thick and the armor of the casemates ranged from 3.1 to 5 in in thickness. The greatest thickness of deck armor was 1.5 in.

Service history
Andrei Pervozvanny was built by the Admiralty Shipyard in Saint Petersburg. Construction began on 15 March 1904 and was officially laid down on 11 May. Her construction was slowed by labor trouble in the shipyard from the 1905 Revolution. She was launched on 30 October 1906 and began her sea trials in September 1910. They were completed in October 1910, but the ship entered service on 10 March 1911. Andrei Pervozvanny joined the Baltic Fleet on completion and she made a port visit to Copenhagen in September 1912. The following September she visited Portland, Cherbourg, and Stavanger together with her sister ship, RUSSIAN BATTLESHIP Imperator Pavel I. She ran aground on Odensholm Island, off the Estonian coast, on 1 July 1914. The ship was still under repair when World War I began the following month. Her lattice masts were cut down and light topmasts were added while under repair.

Andrei Pervozvanny was mostly inactive during the war as the Russian naval strategy in the Baltic was defensive and they did not intend to seek out the German fleet. Torpedo nets were fitted in early 1915 and the ship's torpedoes were removed in January 1916. In late 1916, four 76 mm anti-aircraft guns were added. The ship's crew joined the general mutiny of the Baltic Fleet in Helsinki on 16 March 1917, after they received word of the February Revolution in Saint Petersburg, and several of the ship's officers were murdered by the crew. The Treaty of Brest-Litovsk required the Soviets to evacuate their naval base at Helsinki in March 1918 or have their ships interned by newly independent Finland even though the Gulf of Finland was still frozen over. Andrei Pervozvanny and her sister ship the renamed Respublika, led the second group of ships on 5 April and reached Kronstadt five days later in what became known as the "Ice Voyage".

After the October Revolution in 1918, the ship remained on active duty as part of the Red Navy during the Russian Civil War. Between 13 and 15 June 1919, Andrei Pervozvanny and the dreadnought RUSSIAN BATTLESHIP Petropavlovsk bombarded Fort Krasnaya Gorka whose garrison had mutinied against the Bolsheviks. The ship fired 170 12-inch and 408 8-inch shells and the garrison surrendered on 17 June when Leon Trotsky promised them their lives, only to order them machine-gunned. Andrei Pervozvanny was attacked by the Royal Navy during its Campaign in the Baltic 1918–19, when she was torpedoed by either C.M.B.31 or C.M.B.88 during the night of 17/18 August 1919 as the ship lay at anchor in Kronstadt. She was hit on the port bow and settled 2 ft down by the bow. The British claimed three torpedo hits, but two of the torpedoes actually struck the harbor wall behind the battleship. The Victoria Cross, Britain's highest military decoration, was awarded to Commander Claude Congreve Dobson and Lieutenant Gordon Charles Steele for their successful attack. The ship was raised and docked, but never fully repaired. While under repair, she was nearly hit by a small bomb during a British air raid on 3 September. Scrapping of Andrei Pervozvanny began 15 December 1923, although she was not formally stricken until 21 November 1925.
