The Borodino-class battleships were a group of five

Port Arthur. Three of these ships were sunk and one was captured by the Imperial Japanese Navy at the Battle of Tsushima in 1905. The fifth and final ship, Slava, was not completed in time to participate in the war and served with the Baltic Fleet through World War I

Design and description

Brassey's Naval Annual
1906

Liaotung Peninsula with China. Japan had previously forced China to sign over the port and its surrounding territory as part of the treaty that concluded the First Sino-Japanese War of 1894–1895, but the Triple Intervention of France, Russia, and Germany forced them to return the port in exchange for a sizeable increase in the indemnity paid by the Chinese. Japan invested much of the indemnity money in expanding its fleet, while Russia began a major building programme ("For the Needs of the Far East") to defend its newly acquired port that included the Borodino-class battleships.[1]

The Borodinos were the most numerous class of battleships ever built by Russia. Although they were intended to be near duplicates of Tsesarevich, as soon as the contracts were signed, it became clear that they would be quite different from the French-built ship. The basic problem facing the navy was that the Borodinos would have heavier engines and larger turrets which would require a designer to build a ship which had the same speed, draft, guns and armor as Tsesarevich, but a greater displacement. The new design was drawn up by D. V. Skvortsov of the Naval Technical Committee (NTC). He completed his new design in July/August 1898, one month after the original contract had been signed. The new concept was roughly 1,000 long tons (1,016 t) tons heavier and slightly larger and wider than the Tsesarevich.[2]

As might be expected, the Borodinos greatly resembled Tsesarevich, although Skvortsov added two more casemates, each containing four 75-millimeter (3.0 in) guns, one at the bow and the other aft. These guns were added to the already existing dozen 75 mm guns emplaced along the sides above the armor belt. This caused the tumblehome used on the rest of the hull to be deleted over the twelve guns and flat-sided armor was used in its place. Thus the five Borodino-class battleships had tumblehome hulls only fore and aft of their 75 mm guns emplaced along their sides.[3] The centreline bulkhead between the engine and boiler rooms caused a danger of capsizing if one side flooded and the narrow belt armor became submerged when overloaded. As such, naval historian Antony Preston regarded these as some of the worst battleships ever built.[4]

The ships were 389 feet 5 inches (118.7 m)

long at the waterline and 397 feet 3 inches (121.1 m) long overall, with a beam of 76 feet 1 inch (23.2 m) and a draft of 29 feet 2 inches (8.9 m), 38 inches (965 mm) more than designed. Their normal displacement ranged from 14,091 to 14,145 long tons (14,317 to 14,372 t), 500–900 long tons (508–914 t) more than their designed displacement of 13,516 long tons (13,733 t). They were designed for a crew of 28 officers and 754 enlisted men,[5] although Knyaz Suvorov carried 928 crewmen during the Battle of Tsushima.[6]

The Borodino-class ships were powered by two 4-cylinder

economisers for her boilers as well as three-bladed screws, while her sisters lacked economisers and had four-bladed propellers.[7]

Because the ships were being prepared to go to the

kilowatts (990 hp).[7]

Armament and fire control

The

12-inch guns mounted in French-style, electrically powered, twin-gun turrets fore and aft. The turrets had a maximum elevation of +15° and 60 rounds per gun were carried.[8] The guns fired one shell every 90–132 seconds.[9] They fired a 731-pound (332 kg) shell at a muzzle velocity of 2,598 ft/s (792 m/s)[10] to a range of 16,010 yards (14,640 m) at maximum elevation.[11]
`

The secondary armament of the ships consisted of a dozen 45-caliber

Canet Model 1891 6-inch (152 mm) (QF) guns mounted in six electrically powered twin-gun turrets on the upper deck. The turrets had a maximum elevation of +15° arc of fire and the center turrets could cover 180°. Each six-inch gun was provided with 180 rounds.[8] Their rate of fire was about 2–4 rounds per minute.[12] They fired shells that weighed 91 lb (41.4 kg) with a muzzle velocity of 2,600 ft/s (792.5 m/s).[13] They had a maximum range of approximately 12,600 yards (11,500 m).[12]

A number of smaller guns were carried for defense against

75-millimetre (3 in) guns mounted in hull embrasures. The ships carried 300 shells for each gun.[8] They fired a 11-pound (4.9 kg) shell at a muzzle velocity of 2,700 ft/s (820 m/s) to a maximum range of 7,005 yards (6,405 m) at an elevation of +13°.[14] The Borodino-class ships also mounted sixteen or eighteen 47-millimetre (1.9 in) Hotchkiss guns in the superstructure.[8] They fired a 2.2-pound (1.00 kg) shell at a muzzle velocity of 1,400 ft/s (430 m/s)[15] at a rate of around 15 rounds per minute.[12]

The ships carried four 381-millimetre (15 in) torpedo tubes, two of which were mounted above water in the bow and stern while the two broadside underwater tubes were located near the forward 12-inch magazine. Four torpedoes were carried for the above-water tubes and six for the submerged tubes. They also carried 50 mines to be laid to protect their anchorage in remote areas.[8]

The Borodino class were originally fitted with Liuzhol stadiametric rangefinders that used the angle between two vertical points on an enemy ship, usually the waterline and the crow's nest, to estimate the range. The gunnery officer consulted his references to get the range and calculated the proper elevation and deflection required to hit the target. He then transmitted his commands via a Geisler electro-mechanical fire-control transmission system to each gun or turret. While fitting out, these rangefinders were replaced on the first four ships by two Barr and Stroud coincidence rangefinders that used two images that had to be superimposed to derive the range. Perepelkin telescopic sights were also installed for their guns, but their crews were not trained in how to use them.[8][16]

The

Krupp armor and was 5.7–7.64 inches (145–194 mm) thick. The armor of their gun turrets had a maximum thickness of 10 in (254 mm) and their deck ranged from 1 to 2 inches (25 to 51 mm) in thickness. The 1.5-inch (38 mm) armored lower deck curved downwards and formed an anti-torpedo bulkhead.[17]

Service history

On 15 October 1904, Knyaz Suvorov,

Libau along with the other vessels of the squadron.[24] Rozhestvensky had received numerous reports of Japanese agents and torpedo boats disguised as fishing vessels before sailing and he ordered maximum alertness after coaling at Skagen, Denmark on 7 October. Early on the evening of the following day, when the squadron was near the Dogger Bank, the auxiliary repair ship Kamchatka reported that she was under attack by torpedo boats in the rain. About four hours later, the squadron encountered British fishing trawlers working the Dogger Bank in the fog and opened fire on them at very short range.[25] One trawler was sunk and at least three others were damaged; several fishermen were killed and others wounded.[26] The battleships also fired upon and damaged the cruisers Aurora and Dmitrii Donskoi in the confusion. The incident enraged the British population and caused a diplomatic incident with the British that nearly led to war until Russia apologized and agreed to pay reparations on 29 October.[27]

Rozhestvensky led his ships down the Atlantic coast of Africa, rounding the

Rear Admiral Nikolai Nebogatov. The latter ships reached Camranh Bay on 9 May and the combined force sailed for Vladivostok on 14 May. While exact figures are not available, it is probable that the ships were approximately 1,700 long tons (1,727 t) overweight as they were overloaded with coal and other supplies; all of which was stored high in the ships and reduced their stability. The extra weight also submerged their waterline armor belt and left only about 4 feet 6 inches (1.4 m) of the upper armor belt above the waterline.[28]

Battle of Tsushima

Before the battle Rozhestvensky grouped the four Borodinos into one division and retained personal command of the division. Oryol, the last ship in the division, fired the first shots of the Battle of Tsushima when the ship's

mainmast had been shot away.[30]

Imperator Aleksandr III and the other ships of the division briefly followed Knyaz Suvorov until it became clear that the latter ship was out of control and then turned north in an effort to get behind Tōgō's ships. Knyaz Suvorov never regained her position in the battle line and became the primary target of the Japanese for a time. Around 16:00 the captain of Imperator Alexandr III, Nikolai Bukhvostov, decided to duplicate Retvizan's maneuver at the Battle of the Yellow Sea by charging straight for the Japanese battleline in an attempt to focus their attention on his ship rather than Knyaz Suvorov. He was successful, but Imperator Aleksandr III was badly damaged in the process. Borodino now assumed the lead position and turned the fleet to the south where they temporarily managed to disengage in the mist and fog.[32]

Knyaz Suvorov was badly damaged by repeated attacks after she separated from the main body although she was initially in no danger of sinking. The Russian

Buinyi came alongside around 17:30 and evacuated Rozhestvensky and other wounded officers. Torpedoes fired by a number of torpedo boats ultimately caused a magazine to explode around 19:20 and Knyaz Suvorov capsized at about 19:30.[6] Other than the 20 officers taken off by Buinyi,[33] there were no survivors of the 928 crew aboard.[6]

When the shooting between the battle lines resumed around 18:00, the Japanese concentrated their fire upon Imperator Aleksandr III and Borodino. Imperator Alexandr III sheered out of line to port around 18:30 and

capsized, but did not sink until 19:07; there were no survivors.[33] Borodino lasted a little while longer under concentrated Japanese fire. Two 12-inch hits by the battleship Shikishima at 19:18 started a massive fire and both the ship's 12-inch gun turrets were knocked out. Ten minutes later, after Tōgō ordered his ships to cease fire and disengage, the battleship Fuji fired her already-loaded 12-inch guns before turning away. One of these hit Borodino beneath her starboard forward six-inch turret and ignited the ready-use ammunition in the turret. The fire spread and caused a catastrophic detonation in several magazines that blew open her hull. Borodino quickly capsized and sank with only one crewman from her crew of 855 being rescued.[34][35]

Oryol took the lead after Borodino was sunk; she was joined by Nebogatov's Second Division after Tōgō ordered the Japanese battleships to disengage in the gathering darkness. Nebogatov assumed command of the remains of the fleet and they continued towards Vladivostok. The ships were discovered by the Japanese early the following morning and attacked by Tōgō's battleships around 10:00. The faster Japanese ships stayed beyond the range at which Nebogatov's ships could effectively reply and he decided to surrender his ships at 10:30 as he could neither return fire nor close the range.[36]

Post-Tsushima careers

Iwami at anchor

The Japanese substantially rebuilt Oryol and recommissioned her in June 1907 with the name of Iwami.[37] To reduce her top weight, they cut down her superstructure and repositioned her guns. In addition, her boilers were replaced by an unknown number of Japanese-built Miyabara boilers and she was rearmed with Japanese-made guns. These changes reduced her displacement to approximately 13,500 long tons (13,717 t) and her crew now totaled 750 officers and crewmen.[38]

During World War I, the ship participated in the

intervened in the Russian Civil War.[40] She was used as a training ship in 1921 and disarmed in 1922 in accordance with the terms of the Washington Naval Treaty. Sources differ as to her ultimate fate; she was either sunk as a target by aircraft near Miura in July 1924 or scrapped at Kobe in 1924–1925.[5]

Serving in the

German High Seas Fleet in the Battle of the Gulf of Riga in August 1915. She was lightly damaged by three hits during the battle. She repeatedly bombarded German positions and troops for the rest of 1915 and during 1916.[41] During the Battle of Moon Sound in 1917, Slava was badly damaged by the German dreadnought SMS König and the flooding significantly increased her draft. The shallow channel made it impossible to escape and she was scuttled in the Moon Sound Strait between the island of Muhu (Moon) and the mainland.[42] The Estonians scrapped her in 1935.[43]
