Admiral Spiridov Class Monitor
The ''Admiral Spiridov'' class were a pair of monitors built for the Imperial Russian Navy in the late 1860s. The sister ships were assigned to the Baltic Fleet upon completion and remained there for their entire careers. Aside from several accidental collisions and one grounding, their careers were uneventful. They were reclassified as coast-defense ironclads in 1892 before they became training ships in 1900. The ''Admiral Spiridov''s were stricken from the Navy List in 1907; one ship became a stationary target and the other a coal-storage barge. Their ultimate fates are unknown. Design and description By late 1863, the Russian Admiralty Board had begun planning for the second generation of ironclads to succeed those ships then under construction. They ordered eight ships, two fully rigged seagoing types and six coastal defense ships, in March 1864. The British shipbuilder Charles Mitchell submitted four different designs for the coastal defense vessels, two broadside ironcla ...

Sredne-Nevskiy Shipyard
The Middle Neva Shipbuilding Plant (russian: Средне-Невский судостроительный завод, Sredne-Nevskiy sudostroitelnyy zavod) was founded before the end of the 19th century in Saint Petersburg, Russia. In 1917 it employed 17,000 people. It established a branch in Nikolaev in the early years of the 20th century to assemble ships which had been built in St. Petersburg and transported to the Black Sea.Breyer, p. 144 It is part of the United Shipbuilding Corporation. History The Middle Neva shipyard, located near the junction of the Izhora and Neva rivers in the Kolpino district of southern St. Petersburg, is an important builder of mine warfare ships for the Russian navy. The yard probably dates back to 1911, when the Saint Petersburg Metals Plant, then a builder of marine turbines, established a shipyard at Ust-Izhora to build destroyers. Between the world wars the Ust-Izhora yard was limited to the construction of river barges. It was expanded into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Grounding
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground". When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety. As hazard Severe grounding applies extreme loads upon ship structures. In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties. Grounding accounts for about one-third of commercial ship accidents,Kit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoothbore Gun
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, improvin ...

Turret Ship
Turret ships were a 19th-century type of warship, the earliest to have their guns mounted in a revolving gun turret, instead of a broadside arrangement. Background Before the development of large-calibre, long-range guns in the mid-19th century, the classic ship of the line design used rows of port-mounted guns on each side of the ship, often mounted in casemates. Firepower was provided by a large number of guns which could only be aimed in a limited arc from one side of the ship. Due to instability, fewer larger and heavier guns can be carried on a ship. Also, the casemates often sat near the waterline, which made them vulnerable to flooding and restricted their use to calm seas. Turrets were weapon mounts designed to protect the crew and mechanism of the artillery piece and with the capability of being aimed and fired in many directions as a rotating weapon platform. This platform can be mounted on a fortified building or structure such as an anti-naval land battery, or on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadside Ironclad
An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th century transformed the iro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Mitchell (shipbuilder)
Charles Mitchell (1820 – 22 August 1895) was a Scottish engineer from Aberdeen who founded major shipbuilding yards on the Tyne. He became a public benefactor who funded notable buildings that still survive today. Career He attended Aberdeen University. After an engineering apprenticeship in London, he became a ship designer working for John Coutts' Newcastle upon Tyne yard in 1842. He became a shipbuilder in his own right at the Low Walker yard on the Tyne in 1852. The cable ship ''Hooper'', second in size only to SS ''Great Eastern'' and the first ship designed specifically to lay trans-Atlantic cable, was launched for Hooper's Telegraph Works at the yard on 29 March 1873 after four and a half months construction. That shipyard joined in partnership with the Armstrong yard to form Armstrong Mitchell in 1882. He was decorated with the Imperial Order of St Stanislaus, 2nd class (normal for foreign nationals), which may be seen in the coat of arms over the door of Jesmond ...

Coastal Defense Ship
Coastal defence ships (sometimes called coastal battleships or coast defence ships) were warships built for the purpose of Littoral (military), coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited Blue-water navy, blue-water capabilities; others operated in Maritime geography#Riverine, rivers. The coastal defence ships differed from earlier Monitor (warship), monitors by having a higher Freeboard (nautical), freeboard and usually possessing both higher speed and a secondary armament; some examples also mounted casemated gun ...

Admiralty Board (Russian Empire)
Board of Admiralties (russian: Адмиралтейств-коллегия, ''Admiralteystv-kollegiya'') was a supreme body for the administration of the Imperial Russian Navy and admiralty shipyards in the Russian Empire, established by Peter the Great on December 12, 1718, and headquartered in the Admiralty building, Saint Petersburg. It included several other admiralties of the Imperial Russia among which is the Nikolaev Admiralty. History The responsibilities of the Admiralty Board had been changing throughout its history. It supervised the construction of military ships, ports, harbors, and canals and administered Admiralty Shipyard. The Admiralty Board was also in charge of naval armaments and equipment, preparation of naval officers etc. The first president of the Admiralty Board was Count Fyodor Apraksin. In 1720, the Admiralty Board published a collection of naval decrees called ''Книга - устав морской о всем, что касается доброму у ...

Admiral Spiridov (1869)
Grigory Andreyevich Spiridov () (1713, Vyborg - , Moscow) was a leading Russian naval commander and admiral (1769). Grigory Spiridov began his career in the Russian Navy in 1723. He was promoted to an officer rank in 1733. Spiridov had been commanding different ships of the Baltic Fleet since 1741. During the Seven Years' War of 1756–1763, he was in charge of a landing party of two thousand men when Peter Rumyantsev was laying siege to the fortress of Kolberg in Pomerania. In 1762, Spiridov was promoted to the rank of rear admiral and assigned to command a squadron for securing the contact with the Russian army in Prussia. In 1764, he was appointed commander of the port of Tallinn and then Kronstadt (1766). During the Russo-Turkish War of 1768-1774, Spiridov was in charge of a squadron, which would be sent from the Baltic Sea to the Mediterranean to assist the Greeks in their struggle against the Turks in the summer of 1769 (see Orlov Revolt and First Archipelago Exped ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

Navy List
A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval authorities of a country. Background The Navy List fulfills an important function in international law in that warships are required by article 29 of the United Nations Convention on the Law of the Sea to be commanded by a commissioned officer whose name appears in the appropriate service list. Past copies of the Navy List are also important sources of information for historians and genealogists. The Navy List for the Royal Navy is no longer published in hard-copy. The Royal Navy (United Kingdom) publishes annual lists of active and reserve officers, and biennial lists of retired officers. As of 2015, the Navy List of the Royal Navy has been renamed as the 'Navy Directory'. The equivalent in the United States Navy is the Naval Register, whic ...
