Brazilian Monitor Javary (1874)
''Javary'' was a ''Javary''-class armored monitor operated by the Imperial Brazilian Navy and Brazilian Navy (before and after the Proclamation of the Republic). Her sister ship was the '' Solimões''. She is known for her armor and powerful armaments for the time. Her service was limited by the inadequate draught for certain stretches of river, and her maneuverability was reduced due to an extremely low side, which meant the ship was used mainly as a floating battery. She was sunk after being shot at by the Fortaleza de São João during the Revolta da Armada in 1893. Characteristics The idea of building the ''Javary'' class emerged after ten years had passed since the construction of the first armored ship of the Empire: '' Brasil''. According to Ribeiro de Luz, "these ironclad battleships would be endowed with all the improvements needed to make them perfect machines for both maritime and river warfare." However, this finding turned out not to be true, as the future b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortaleza De São João (Rio De Janeiro)
The Fortaleza de São João da Barra do Rio de Janeiro ( Portuguese for: Fortress of Saint John of the Harbor of Rio de Janeiro), popularly known as the Fortaleza de São João or Forte (de) São João (Fort (of) Saint John), is a 16th-century star fort in the present-day Urca neighborhood of Rio de Janeiro, erected by Estácio de Sá to protect Guanabara Bay from French invasion.Espaço Cultural: Fortaleza de São João, RJ History The original fort was built in 1565 under King Sebastian of Portugal. An expanded and improved structure was put into service in 1618, consisting of four batteries (São José, São Martinho, São Teodósio, and São Diogo).

Bow (watercraft)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military vess ...

Evolutions Squadron
The Evolution Squadron was a naval squadron of the Brazilian Imperial Fleet composed of the best ships of its time in several characteristics. It was created in 1884 with the purpose of developing new naval tactics inspired by the Austria tactics in the Battle of Lissa where its naval force faced and defeated the much superior Italian fleet. History Origins After the end of the Paraguayan War, Brazil was concerned with repairing the damage caused to its vessels, refitting them and transforming the Armada into the fourth most powerful navy in the world. From 1870, with the possibility of a conflict with Argentina, the Brazilian Empire aimed to further strengthen its Armada. In 1873 it acquired a gunboat and a corvette; a battleship and a monitor in 1874 and soon after two cruisers and another monitor. In the 1880s, the navy continued its program of strengthening it, with several Brazilian arsenals building dozens of warships. Four torpedo boats were purchased, the Escola Prá ...

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 ...

Nordenfelt Gun
The Nordenfelt gun was a multiple-barrel organ gun that had a row of up to twelve barrels. It was fired by pulling a lever back and forth and ammunition was gravity fed through chutes for each barrel. It was produced in a number of different calibres from rifle up to 25 mm (1 inch). Larger calibres were also used, but for these calibres the design simply permitted rapid manual loading rather than true automatic fire. This article covers the anti-personnel rifle-calibre (typically 0.45 inch) gun. Development The weapon was designed by a Swedish engineer, Helge Palmcrantz. He created a mechanism to load and fire a multiple barreled gun by simply moving a single lever backwards and forwards. It was patented in 1873. Production of the weapon was funded by a Swedish steel producer and banker (later weapons maker) named Thorsten Nordenfelt, who was working in London. The name of the weapon was changed to the Nordenfelt gun. A plant producing the weapon was set up in Engla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile ().
