6 Inch 35 Caliber Naval Gun 1877
The 6 inch 35 caliber naval gun 1877 was a 152 mm naval gun used by the Russian Empire. The gun was used from 1887 as battleship secondary armament and cruiser armament. The gun was mostly replaced by newer 6 inch 45 caliber Canet gun 1892 at the time of the Russo-Japanese War, but was still used on some ships. During the First World War fourteen guns were used as a coastal guns on Gulf of Finland in the Peter the Great's Naval Fortress and were taken over by Finland after Finland's Declaration of Independence in 1917. The guns were used by Finland in the Second World War. Russian model year 1877 refers to rifling system, not gun adoption. Background Russian Empire Stabskapitän, Staff captain A.F. Brink had developed plans for a new six inch 35 caliber gun that was able to withstand 20% higher barrel pressures than existing guns. In 1882 development began for a new six inch naval gun that resulted in Brink's design being selected. Based on gun barrel material strength t ...

Suomenlinna
Suomenlinna (; until 1918 Viapori, ), or Sveaborg (), is an inhabited sea fortress the Suomenlinna district is on eight islands of which six have been fortified; it is about 4 km southeast of the city center of Helsinki, the capital of Finland. Suomenlinna is popular with tourists and locals who enjoy it as a picturesque picnic site. Originally named ''Sveaborg'' (Castle of the Swedes), or ''Viapori'' as referred to by Finnish-speaking Finns, it was renamed in Finnish to ''Suomenlinna'' (Castle of Finland) in 1918 for patriotic and nationalistic reasons, though it is still known by its original name in Sweden and by Swedish-speaking Finns. The Swedish crown commenced the construction of the fortress in 1748 as protection against Russian expansionism. The general responsibility for the fortification work was given to Augustin Ehrensvärd. The original plan of the bastion fortress was strongly influenced by the ideas of Vauban, the foremost military engineer of the time, and ...

Peter The Great's Naval Fortress
Peter the Great's Naval Fortress or the Tallinn-Porkkala defence station was a Russian fortification line, which aimed to block access to the Russian capital Saint Petersburg via the sea. The plans for the fortress included heavy coastal artillery pieces along the northern and southern shores of the Gulf of Finland. The emphasis was put on the defenses of the gulf's narrowest point, between Porkkala, (in current day Finland) and Tallinn, (in current day Estonia). This was a strategic point, as the two fortresses of Mäkiluoto and Naissaar were only 36 kilometers apart. The coastal artillery had a range of about 25 kilometers and could thus "close" the gap between the shores, trapping enemy ships in a crossfire. Furthermore, a new major naval base was constructed in Tallinn. Purpose The decision to start construction of the naval fortress line came after the disastrous events at Tsushima, where the whole Russian Baltic Fleet had been annihilated. The road to Saint Petersburg was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Battleship Gangut (1888)
''Gangut'' (Russian: броненосец "Гангут") was an Imperial Russian coast defense ship named after the Battle of Gangut. This ship was a scaled-down version of the s. Design and construction The ship was designed as a smaller version of the on the instruction of Navy Minister Ivan Shestakov. The aim was to have a cheaper vessel able to operate in the shallow water of the Baltic Sea with long range deployment to the Mediterranean and the Far East. The specification was issued in 1887 and the design was approved by the Marine Technical Committee in 1888. She was built by New Admiralty yard, Saint Petersburg. Construction started on 29 October 1888, and she was launched on 3 July 1893. Completed in 1894, she was 600 tons over her designed displacement which led to an increase in draught and a loss in speed. Her trials were difficult and she had to return to Kronstadt to have repairs after 19 days. Several modernisation schemes to correct the defects were cons ...

Imperator Aleksandr II-class Battleship
The ''Imperator Aleksandr II''-class battleships were two battleships built for the Imperial Russian Navy in the 1880s. They were intended to counter the small armored ships of the other Baltic powers. Construction was very prolonged and the ships were virtually obsolescent when completed. They were optimized for ramming. served in the Baltic and Mediterranean Seas before becoming a gunnery training ship in 1904, but she was inactive during World War I before joining the Bolsheviks in 1917. She was sold for scrap in 1922. ''Imperator Nikolai I'' served in the Baltic and Mediterranean Seas as well as the Pacific Ocean during the First Sino-Japanese War and the Russo-Japanese War. She surrendered after the Battle of Tsushima in 1905 and was commissioned in the Imperial Japanese Navy before she was sunk as a target in 1915. Design The ''Imperator Aleksandr II''-class battleships were the first all-steel battleships to be built for the Baltic Fleet and were designed to allow Russia ...

Ekaterina II-class Battleship
The ''Ekaterina II'' class were a class of four battleships built for the Imperial Russian Navy in the 1880s. They were the first battleships built for the Black Sea Fleet. Their design was highly unusual in having the main guns on three barbettes grouped in a triangle around a central armored redoubt, two side-by-side forward and one on the centerline aft. This was intended to maximize their firepower forward, both when operating in the narrow waters of the Bosphorus and when ramming. Construction was slow because they were the largest warships built until then in the Black Sea, and the shipyards had to be upgraded to handle them. All four ships were in Sevastopol when the crew of the battleship mutinied in June 1905. s crew was considered unreliable, and she was disabled to prevent her from joining the mutiny. s crew was also considered unreliable, but she did escort ''Potemkin'' as towed her back to Sevastopol from Constanța, Romania, where ''Potemkin''s crew had sought asy ...

Pre-dreadnought Battleship
Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of in 1906. The pre-dreadnought ships replaced the ironclad battleships of the 1870s and 1880s. Built from steel, protected by case-hardened steel armour, and powered by coal-fired triple-expansion steam engines, pre-dreadnought battleships carried a main battery of very heavy guns in fully enclosed rotating turrets supported by one or more secondary batteries of lighter weapons. In contrast to the multifarious development of ironclad warships in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's . The similarity in appearance of battleships in the 1890s was underlined by the increasing number of ships being built. New naval powers such as Germany, Japan, the United States, and to a lesser extent Italy and Austria-Hungary, began to establish ...

Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval school. From 1818 on, only officers of the Imperial Russian Navy were appointed to the position of Chief Manager of the Russian-American Company, based in Russian America (present-day Alaska) for colonization and fur-trade deve ...

Casemate
A casemate is a fortified gun emplacement or armored structure from which guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a protected space for guns in a ship, either within ...

Kirov Plant
The Kirov Plant, Kirov Factory or Leningrad Kirov Plant (LKZ) ( rus, Кировский завод, Kirovskiy zavod) is a major Russian mechanical engineering and agricultural machinery manufacturing plant in St. Petersburg, Russia. It was established in 1789, then moved to its present site in 1801 as a foundry for cannonballs. The Kirov Plant is sometimes confused with another Leningrad heavy weapons manufacturer, '' Factory No. 185 (S.M. Kirov)''. Recently the main production of the company is Kirovets heavy tractors. History In 1868 Nikolay Putilov (1820-1880) purchased the bankrupt plant; at the Putilov Works the Putilov Company (a joint-stock holding company from 1873) initially produced rolling stock for railways. The establishment boomed during the Russian industrialization of the 1890s, with the work-force quadrupling in a decade, reaching 12,400 in 1900. The factory traditionally produced goods for the Russian government, with railway products accounting for mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canet Gun
The Canet guns were a series of weapon systems developed by the French engineer Gustave Canet (1846–1908), who worked as an engineer from 1872 to 1881 for the London Ordnance Works, then for Forges et Chantiers de la Méditerranée, and from 1897 to 1907 for Schneider et Cie of Le Creusot. 320 mm naval guns Canet developed a 38 cal naval gun, an extremely powerful weapon for its time, specifically for the export market. The gun was first selected by the Spanish Navy in 1884 as part of a large naval expansion program which called for six new battleships. The Spanish armaments firm Hontoria obtained a manufacturing license to produce the weapon, but due to budgetary reasons, only one vessel, the , was completed. Canet was more successful in sales to the Empire of Japan, when the gun was selected by the French military advisor and naval architect Louis-Émile Bertin as the main battery of the , new type of cruiser he had designed in 1887. The usage was consistent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Bange
Charles Ragon de Bange (17 October 1833 – 9 July 1914) was a French artillery officer and Polytechnician. He invented the first effective obturator system for breech-loading artillery, which remains in use. He also designed a system of field guns of various calibers which served the French Army well into World War I: the ''Système de Bange''. Career De Bange breech obturator system Many attempts had been made at developing breech-loading cannons, but had only partial success sealing of the breech. When fired, hot gases and burning gunpowder could escape, losing power and potentially burning the operating crew. Rifles, with smaller loads and thus less stress, were able to use rubber in O-rings as on the Chassepot rifle. The same principle of breech sealing applied on cannons was not as easy to develop. Several materials were able to hold the pressure and heat of cannon fire, but did not expand like rubber, thereby failing to provide a tight seal. The most successful of ...

Antoine Treuille De Beaulieu
Count Antoine Hector Thésée Treuille de Beaulieu (7 May 1809 – 24 July 1885) was a French General of the 19th century, who developed the concept of rifled guns in the French Army. He studied the subject of rifling between 1840, particularly in the famous Manufacture d'armes de Châtellerault, and 1852. Following a request by Napoleon III in 1854 to develop such a weapon, the de Beaulieu system was adopted by the French Army. It consisted in cutting six grooves inside the bore of a muzzle-loading cannon, and to use shells equipped with six lugs which would engage the grooves.''A Dictionary of Military History and the Art of War'' by André Corvisier, p.4/ref> This development was paralleled by that of the Armstrong gun in Great Britain (adopted in 1858 by the British Army). About the same time he developed a pinfire falling-block breech-loading carbine (''mousqueton'') for the Cent-gardes Squadron which was a bit ahead of its time in using a metallic cartridge and is very unusu ...
