SMS ''M68''), group=lower-alpha was a M1916 type minesweeper built for the Imperial German Navy during the First World War. She entered service on 6 October 1917, but was mined and sunk off Latvia on 29 October 1917. The ship was salvaged by Latvia and entered service with the Latvian Navy on 10 November 1921 under the name ''Virsaitis'' as its first vessel. She was taken over by the Soviet Navy in August 1940 when the Soviet Union occupied Latvia in August 1940, serving as ''T-297'' and was sunk by a mine on 2 December 1941. Design and construction The M1916 Type minesweeper was an improved and slightly enlarged derivative of the M1914 and M1915 Type minesweepers which Germany had built since 1914. They were fleet minesweepers, seaworthy enough to operate in the open sea, and proved to be successful and reliable in service. ''M68'' was long overall and at the waterline, with a beam of and a draught of . The ship had a design displacement of and a deep load displac ...

German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years.

Soviet–Latvian Mutual Assistance Treaty
The Soviet–Latvian Mutual Assistance Treaty (russian: Пакт о взаимопомощи между СССР и Латвийской Республикой, lv, Savstarpējās palīdzības pakts starp Latviju un PSRS) was a bilateral treaty between the Soviet Union and Latvia, signed in Moscow on October 5, 1939. The treaty obliged both parties to respect each other's sovereignty and independence, while in practice allowed the Soviet government to establish military bases in Latvia, which facilitated the Soviet invasion of the country in June 1940. It was signed by Latvian Minister of Foreign Affairs Vilhelms Munters and Soviet Commissar of Foreign Affairs Vyacheslav Molotov. Ratifications were exchanged in Riga on October 11, 1939, and the treaty became effective on the same day. It was registered in League of Nations Treaty Series on November 6, 1939. Background On 23 August 1939 the Soviet Union asserted its control over the Baltic states with the Molotov–Ribbentr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latvian Provisional Government
The Latvian Provisional Government ( lv, Latvijas Pagaidu valdība) was formed on November 18, 1918 by the People's Council of Latvia as the interim government of the newly-proclaimed Republic of Latvia during the Latvian War of Independence. The term encompasses three cabinets led by Kārlis Ulmanis, the leader of the Agrarian Union, who was chosen to be Prime Minister. The Ulmanis' government led the country until the formation of an elected cabinet after the elections to the Constitutional Assembly of Latvia in June 1920. History After the Proclamation of the Independence of the Republic of Latvia on November 18, 1918, the interim parliament – the People's Council of Latvia – chose Kārlis Ulmanis to form the country's first government. In December, the first ministries were created. From December 1918 until May 1919, the Latvian territories (that were not under German occupation) were invaded and controlled by a provisional Soviet Latvian government led by Pēteris St ...

Latvian War Of Independence
The Latvian War of Independence ( lv, Latvijas Neatkarības karš), sometimes called Latvia's freedom battles () or the Latvian War of Liberation (), was a series of military conflicts in Latvia between 5 December 1918, after the newly proclaimed Republic of Latvia was invaded by Soviet Russia, and the signing of the Latvian-Soviet Riga Peace Treaty on 11 August 1920. The war can be divided into a few stages: Soviet offensive, German-Latvian liberation of Kurzeme and Riga, Estonian-Latvian liberation of Vidzeme, Bermontian offensive, Latvian-Polish liberation of Latgale. The war involved Latvia (its provisional government supported by Estonia, Poland and the Western Allies—particularly the navy of United Kingdom) against the Russian SFSR and the Bolsheviks' short-lived Latvian Socialist Soviet Republic. Germany and the Baltic nobility added another level of intrigue, initially being nominally allied to the Nationalist/Allied force but attempting to jockey for German domina ...

Latvian Socialist Soviet Republic
The Latvian Socialist Soviet Republic ( lv, Latvijas Sociālistiskā Padomju Republika, LSPR) was a short-lived socialist republic formed during the Latvian War of Independence. It was proclaimed on 17 December 1918 with the political, economic, and military backing of Vladimir Lenin and his Bolshevik government in the Russian SFSR. The head of government was Pēteris Stučka with Jūlijs Daniševskis as his deputy. History The LSPR armed forces, which consisted of the Red Latvian Riflemen and other units of the Red Army, quickly captured most of the territory of present-day Latvia, forcing Kārlis Ulmanis's provisional government into a small pocket of territory around the city of Liepāja. Stučka's government introduced sweeping communist reforms, resuming the radical policy direction from the abortive Iskolat government. Some reforms were initially popular, such as the expropriation of property from the bourgeoisie. The decision to unilaterally nationalise all agrarian ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Neptun Werft
Neptun Werft is a German shipbuilding company, headquartered in Rostock. Since 1997 it has been part of the Meyer Neptun Group together with Meyer Werft in Papenburg. History The company was founded as the "Schiffswerft und Maschinenfabrik von Wilhelm Zeltz und Albrecht Tischbein" in 1850 and their first iron steamship was launched in 1851. The shipyard developed quickly, and as early as in 1857 it had some 400 employees. In 1890, after several mergers and buyouts, it became the "Actien-Gesellschaft Neptun". After 1945 and the division of Germany, the shipyard focused on markets in Eastern Europe. At that time the "Schiffswerft Neptun Rostock" counted among the most renowned state-owned shipyards of the German Democratic Republic. The changing conditions of international competition following the German reunification brought about a time of change for the company. Productivity was not up to international standards, and due to EU restrictions it was no longer allowed to build ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
