Ronis-class Submarine
The ''Ronis''-class submarines were built for the Latvian Navy in France in 1925. They were acquired by the Soviets in 1940 following the annexation of Latvia by the Soviet Union. They were scuttled in Liepāja in June 1941 as the Germans were about to capture the port. The hulls were raised in 1942 and scrapped. Design The boats were small coastal submarines built to a French design. Ronis means " seal" in the Latvian language, Spīdola is a character from the Latvian language poem ''Lāčplēsis''. The submarines were long overall with a beam of and a draught of . The vessels of the class displaced surfaced and submerged. The submarines had a dived depth of . They had a complement of 27 officers and ratings. The ''Ronis''-class submarines were propelled by two shafts driven by two Sulzer diesel engines for travel on the surface, rated at and two electric motors for subsurface movement. The submarines had a maximum speed of surfaced and submerged. They were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Submarine
A coastal submarine or littoral submarine is a small, maneuverable submarine with shallow draft well suited to navigation of coastal channels and harbors. Although size is not precisely defined, coastal submarines are larger than midget submarines, but smaller than sea-going submarines designed for longer patrols on the open ocean. Space limitations aboard coastal submarines restrict fuel availability for distant travel, food availability for extended patrol duration, and number of weapons carried. Within those limitations, however, coastal submarines may be able to reach areas inaccessible to larger submarines, and be more difficult to detect. History The earliest submarines were effectively coastal submarines, but as modern submarine tactics developed during World War I, the advantages of rapid construction and portability encouraged development of UB torpedo launching, and UC minelaying coastal submarines in 1915 to operate in the English Channel. These coastal submarine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minesweeper
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing Grappling hook, grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Le Havre
Le Havre (, ; nrf, Lé Hâvre ) is a port city in the Seine-Maritime department in the Normandy region of northern France. It is situated on the right bank of the estuary of the river Seine on the Channel southwest of the Pays de Caux, very close to the Prime Meridian. Le Havre is the most populous commune of Upper Normandy, although the total population of the greater Le Havre conurbation is smaller than that of Rouen. After Reims, it is also the second largest subprefecture in France. The name ''Le Havre'' means "the harbour" or "the port". Its inhabitants are known as ''Havrais'' or ''Havraises''. The city and port were founded by King Francis I in 1517. Economic development in the Early modern period was hampered by religious wars, conflicts with the English, epidemics, and storms. It was from the end of the 18th century that Le Havre started growing and the port took off first with the slave trade then other international trade. After the 1944 bombings the firm of Auguste ...

Ateliers Et Chantiers Augustin Normand
An atelier () is the private workshop or studio of a professional artist in the fine or decorative arts or an architect, where a principal master and a number of assistants, students, and apprentices can work together producing fine art or visual art released under the master's name or supervision. Ateliers were the standard vocational practice for European artists from the Middle Ages to the 19th century, and common elsewhere in the world. In medieval Europe this way of working and teaching was often enforced by local guild regulations, such as those of the painters' Guild of Saint Luke, and of other craft guilds. Apprentices usually began working on simple tasks when young, and after some years with increasing knowledge and expertise became journeymen, before possibly becoming masters themselves. This master-apprentice system was gradually replaced as the once powerful guilds declined, and the academy became a favored method of training. However, many profession ...

Nantes
Nantes (, , ; Gallo: or ; ) is a city in Loire-Atlantique on the Loire, from the Atlantic coast. The city is the sixth largest in France, with a population of 314,138 in Nantes proper and a metropolitan area of nearly 1 million inhabitants (2018). With Saint-Nazaire, a seaport on the Loire estuary, Nantes forms one of the main north-western French metropolitan agglomerations. It is the administrative seat of the Loire-Atlantique department and the Pays de la Loire region, one of 18 regions of France. Nantes belongs historically and culturally to Brittany, a former duchy and province, and its omission from the modern administrative region of Brittany is controversial. Nantes was identified during classical antiquity as a port on the Loire. It was the seat of a bishopric at the end of the Roman era before it was conquered by the Bretons in 851. Although Nantes was the primary residence of the 15th-century dukes of Brittany, Rennes became the provincial capital after th ...

Ateliers Et Chantiers De La Loire
Ateliers et Chantiers de la Loire (ACL) was a French shipbuilding company of the late 19th and early 20th century. The name translates roughly to English as "Workshops and Shipyard of the Loire". Early years In the eighteenth century Nantes had been the biggest French port, and the Loire had a major shipbuilding industry. A prime example was Dubigeon established in 1760. In the nineteenth century Nantes was surpassed by Le Havre and Marseille. In the first half of the nineteenth century a port was developed at Saint-Nazaire for ships that could no longer reach Nantes. In the second half of the nineteenth century industrialization got under way in Nantes and Saint-Nazaire. In 1861 a Scottish engineer founded the Chantiers de Penhoët at Saint-Nazaire. Ateliers et Chantiers de la Loire (ACL) was formed in 1881 in Nantes by Jollet Babin to take advantage of the expansion of the French Navy. The shipyard was built at Prairie du Lac, near the Dubigeon yard, and the following yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck Gun
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally r ...
