Passage Of Humaitá
The Passage of Humaitá ( Portuguese: ''Passagem de Humaitá'') was an operation of riverine warfare during the Paraguayan War − the most lethal in South American history − in which a force of six Imperial Brazilian Navy armoured vessels was ordered to dash past under the guns of the Paraguayan fortress of Humaitá. Some competent neutral observers had considered that the feat was very nearly impossible. The purpose of the exercise was to stop the Paraguayans resupplying the fortress by river, and to provide the Empire of Brazil and its Allies with a much-needed propaganda victory. The attempt took place on 19 February 1868 and was successful – the attackers had hit upon the fortress' Achilles heel. It restored the reputation of the Brazilian navy and the Brazilian Empire's financial credit, and caused the Paraguayans to evacuate their capital Asunción. Some authors have considered that it was the turning point or culminating event of the war. The fortress, by then ful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DCNS (company)
Naval Group is a major French industrial group specialized in naval defense design, development and construction. Its headquarters are located in Paris. Heir to the French naval dockyards initiated in 1631 by Cardinal Richelieu and to the Direction des Constructions et Armes Navales (''DCAN''), which became Direction des Constructions Navales (''DCN'') in 1991 and then DCNS in 2007, the company was rebranded ''Naval Group'' in 2017. Its two main shareholders are the French State (62.49%) and Thales Group (35%). Naval Group employs nearly 16,000 people across 18 countries. History Naval Group has a heritage of almost 400 years. Major shipyards were built in France in Brest (1631), Nantes-Indret (1771), Lorient (1778) and, subsequently, in Cherbourg (1813). Others were to follow. As early as 1926, what we know as Naval Group today already had all the facilities now owned by the group in mainland France. The birth of the naval dockyards In 1624, Cardinal Richelieu, who was King ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built In Brazil
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Attack Submarines
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet Navy, Soviet and Russian Navy, Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and Ballistic missile submarine, missile submarines. Some attack subs are also armed with submarine-launched cruise missile, cruise missiles, increasing the scope of their potential missions to include land targets. Attack submarines may be either Nuclear marine propulsion, nuclear-powered or diesel-electric ("conventionally") powered. In the United States Navy hull classification symbol, naming system, and in the equivalent NATO system (STANAG 1166), nuclear-powered attack submarines are known as SSN (hull classification symbol), SSNs and their Anti-submarine warfare, anti-submarine (ASW) diesel-electric predecessors are SSK (hull ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraguayan War
The Paraguayan War, also known as the War of the Triple Alliance, was a South American war that lasted from 1864 to 1870. It was fought between Paraguay and the Triple Alliance of Argentina, the Empire of Brazil, and Uruguay. It was the deadliest and bloodiest inter-state war in Latin American history. Paraguay sustained large casualties, but the approximate numbers are disputed. Paraguay was forced to cede disputed territory to Argentina and Brazil. The war began in late 1864, as a result of a conflict between Paraguay and Brazil caused by the Uruguayan War. Argentina and Uruguay entered the war against Paraguay in 1865, and it then became known as the "War of the Triple Alliance". After Paraguay was defeated in conventional warfare, it conducted a drawn-out guerrilla resistance, a strategy that resulted in the further destruction of the Paraguayan military and the civilian population. Much of the civilian population lost their lives due to battle, hunger, and disease. The guer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
