French Navy
–
The French Navy, informally La Royale, is the maritime arm of the French Armed Forces. As of June 2014, the French Navy employed a total of 36,776 personnel, the reserve element of the French Navy consisted of 4,827 personnel of the Operational Reserve. The French naval fleet includes more than a hundred vessels and nuclear type submarines, the history of the French Navy dates back to the History of the French Navy of Antiquity to the Renaissance, part of the History of the French Navy. The French Royal Navy was quasi inexistent prior 1624, the Ordre de Saint-Jean de Jérusalem, which was both a religious and military order, had its own respective international war fleet which assured the policing of the seas in the Mediterranean. The members which had satisfied obligations for periods in service at sea fulfilling their service, were granted the rank of Knights Hospitaller, however, many considered the naval service formation to integrate later, while being well formed, their respective navy. The Ordre de Saint-Jean de Jérusalem was one of the ancestors of the French naval schools and in principal, the Order accordingly formed most of the ships Captains, Officers of the French Royal Navy and Admirals of the Marine française de guerre de la Méditerranée. During the Revolution, the French Navy succeeded to the French Royal Navy, under the First French Empire and the Second French Empire, the navy was designated as the Imperial French Navy. The French Navy is still designated today familiarly as La Royale and this expression was used by commercial sailors due to their military service at the corps of the navy by the institution of maritime inscription. The implementation then of the Ministère de la Marine later the de la Marine de guerre française at rue Royale. The symbol of the French Navy, which was since origin a golden anchor » and this symbol featured on all naval vessels, the arms, uniforms, the couriers, equipment, and general arms of the navy. This symbol was replaced in 1990 by a logo featuring a bow section of a warship with two ascending red and blue spray foams, and the inscription Marine nationale. The Chief of Staff of the French Navy was Admiral Bernard Louzeau, the navy became a consistent instrument of national power around the seventeenth century with Richelieus efforts under Louis XIII, and Colberts under Louis XIV. Under the tutelage of the Sun King, the French Navy was well-financed and -equipped, managing to score several victories in the Nine Years War against the Royal Navy. Financial troubles, however, forced the navy back to port and allowed the English, before the Nine Years War, in the Franco-Dutch War, it managed to score a decisive victory over a combined Spanish-Dutch fleet at the Battle of Palermo. The French Navy scored various successes, as in the campaigns led in the Atlantic by Picquet de la Motte, in 1766, Bougainville led the first French circumnavigation. During the American Revolutionary War the French Navy played a role in supporting the Americans. French warships participated in the battle by bombarding British ground forces, in India, Suffren waged campaigns against the British, successfully contending for supremacy against Vice-Admiral Sir Edward Hughes. In the Mediterranean, the French Navy waged a campaign during a 1798 French invasion of Egypt

Portuguese Navy
–
The Portuguese Navy, tracing back to the 12th century, is one of the oldest continuously serving navies in the world. The navy played a key role at the beginning and during the voyages of the Age of Discoveries in the 15th and 16th centuries. Bartolomeu Dias rounded the tip of Africa and Vasco da Gama reached India, linking Europe and Asia for the first time by ocean route, as well as the Atlantic. The Portuguese Navy also participates in missions related with international commitments assumed by Portugal, the first known battle of the Portuguese Navy happened in 1180, during the reign of Portugals first king, Afonso I. The battle occurred when a Portuguese fleet commanded by the knight Fuas Roupinho defeated a Muslim fleet near Cape Espichel, Fuas Roupinho also made two incursions at Ceuta, in 1181 and 1182, and died during the latter of these attempts to conquer the North African city. During the 13th century, in the Portuguese Reconquista, the Navy helped in the conquest of several coastal Moorish towns, like Alcácer do Sal, Silves and Faro. It was also used in the battles against Castile through incursions in Galicia and Andalusia, in 1317, King Denis decided to give, for the first time, a permanent organization to the Royal Navy, appointed Manuel Pessanha of Genoa to be the first Admiral of the Kingdom. In 1321, the Navy successfully attacked Muslim ports in North Africa, Maritime insurance began in 1323 in Portugal, and between 1336 and 1341 the first attempts at maritime expansion are made, with the expedition to Canary Islands, sponsored by King Afonso IV. In the context of the 1383–85 Crisis, the Portuguese Navy took a participation in the war against Castile. In July 1384, the Portuguese Navy was able to break the Castilian siege of Lisbon and to supply the city, defeating the Castilian Navy in the naval battle of the Tagus. At the end of the 14th century, more Portuguese discoveries were made, with the Navy playing a role in the exploration of the oceans. Portugal became the first naval world power, in the beginning of the 15th century, the country entered a period of peace and stability. Europe was still involved in wars and feudal conflicts which allowed Portugal to be the only country to methodically and successfully start the exploration of the Atlantic. Exploration in the west African coast started in 1412 and ended with the crossing of the Cape of Good Hope in 1488, after his return from Ceuta, Henry the navigator founded a school of navigation in Sagres, which was a place to discuss the art of navigation. The vessel employed in the beginning of the Discoveries was the caravel, the first results came soon and Gonçalves Zarco discovers the Porto Santo Island in 1419 and the Madeira Island in 1420, Diogo de Silves discovers the azorean island of Santa Maria in 1427. In 1424, Gil Eanes crosses the Cape Bojador, Diogo Cão and Bartolomeu Dias arrived to the mouth of the Zaire River in 1482. In the same year, the São Jorge da Mina castle is built in the coast of Western Africa, by Diogo de Azambuja, in 1488, Bartolomeu Dias becomes the first European to sail around the southernmost tip of Africa, the Cape of Good Hope. João Vaz Corte-Real arrives to Newfoundland in 1473, part of the coast of Newfoundland would be charted by the Corte-Real brothers, sons of João Vaz Corte-Real, in a failed attempt to find the Northwest Passage in 1501

France
–
France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Biplane
–
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, while a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs, they permit lighter wing structures, low wing loading, however, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above, the term is also occasionally used in biology, to describe the wings of some flying animals. In a biplane aircraft, two wings are placed one above the other, either or both of the main wings can support ailerons, while flaps are more usually positioned on the lower wing. Bracing is nearly always added between the upper and lower wings, in the form of wires and/or slender interplane struts positioned symmetrically on either side of the fuselage. The primary advantage of the biplane over the traditional single plane or monoplane is to combine great stiffness with light weight. A braced monoplane wing must support itself fully, while the two wings of a help to stiffen each other. The biplane is therefore inherently stiffer than the monoplane, also, the structural forces in the spars of a biplane wing tend to be lower, so the wing can use less material to obtain the same overall strength and is therefore much lighter. A disadvantage of the biplane was the need for extra struts to space the wings apart, the low power supplied by the engines available in the first years of aviation meant that aeroplanes could only fly slowly. This required an even lower stalling speed, which in turn required a low wing loading, combining both large wing area with light weight. A biplane wing of a span and chord has twice the area of a monoplane the same size and so can fly more slowly. Alternatively, a wing of the same area as a monoplane has lower span and chord, reducing the structural forces. Biplanes suffer aerodynamic interference between the two planes and this means that a biplane does not in practice obtain twice the lift of the similarly-sized monoplane. The farther apart the wings are spaced the less the interference, given the slow speed and low power of early aircraft, the drag penalty of the wires and struts and the mutual interference of airflows were relatively minor and acceptable factors. The smaller biplane wing also allows greater maneuverability, during World War One, this further enhanced the dominance of the biplane and, despite the need for speed, military aircraft were among the last to abandon the biplane form. Specialist sports Aerobatic biplanes are still occasionally made, biplanes were originally designed with the wings positioned directly one above the other

Flying boat
–
A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water, that usually has no type of landing gear to allow operation on land. It differs from a floatplane as it uses a purpose-designed fuselage which can float, Flying boats may be stabilized by under-wing floats or by wing-like projections from the fuselage. Flying boats were some of the largest aircraft of the first half of the 20th century and their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also used for maritime patrol and air-sea rescue. Their use gradually trailed off after World War II, partially because of the investments in airports during the war. In the 21st century, flying boats maintain a few uses, such as dropping water on forest fires, air transport around archipelagos. Many modern seaplane variants, whether float or flying boat types, are convertible amphibious aircraft where either landing gear or flotation modes may be used to land, on 6 June 1905 Gabriel Voisin took off and landed on the River Seine with a towed kite glider on floats. The first of his flights was 150 yards. He later built a powered floatplane in partnership with Louis Blériot, other pioneers also attempted to attach floats to aircraft in Britain, Australia, France and the USA. On 28 March 1910 Frenchman Henri Fabre successfully flew the first successful powered seaplane, the Gnome Omega-powered hydravion, fabres first successful take off and landing by a powered seaplane inspired other aviators and he designed floats for several other flyers. The first hydro-aeroplane competition was held in Monaco in March 1912, featuring aircraft using floats from Fabre, Curtiss, Tellier and this led to the first scheduled seaplane passenger services at Aix-les-Bains, using a five-seat Sanchez-Besa from 1 August 1912. The French Navy ordered its first floatplane in 1912, in 1911-12 François Denhaut constructed the first seaplane with a fuselage forming a hull, using various designs to give hydrodynamic lift at take-off. Its first successful flight was on 13 April 1912, throughout 1910 and 1911 American pioneering aviator Glenn Curtiss developed his floatplane into the successful Curtiss Model D land-plane, which used a larger central float and sponsons. Combining floats with wheels, he made the first amphibian flights in February 1911 and was awarded the first Collier Trophy for US flight achievement, from 1912 his experiments with a hulled seaplane resulted in the 1913 Model E and Model F, which he called flying-boats. In February 1911 the United States Navy took delivery of the Curtiss Model E, in Britain, Captain Edward Wakefield and Oscar Gnosspelius began to explore the feasibility of flight from water in 1908. They decided to use of Lake Windermere in the Lake District. Meanwhile, Wakefield ordered a similar to the design of the 1910 Fabre Hydravion. By November 1911, both Gnosspelier and Wakefield had aircraft capable of flight from water and awaited suitable weather conditions, gnosspeliers flight was short-lived as the aircraft crashed into the lake

Rotary engine
–
Its main application was in aviation, although it also saw use before its primary aviation role, in a few early motorcycles and automobiles. This type of engine was used as an alternative to conventional inline engines during World War I. It has been described as an efficient solution to the problems of power output, weight. The rotating mass of the engine also caused significant gyroscopic precession, depending on the type of aircraft, in the most common form, the crankshaft was fixed solidly to the airframe, and the propeller was simply bolted to the front of the crankcase. Improved cooling, when the engine was running the rotating crankcase/cylinder assembly created its own fast-moving cooling airflow, weight advantage, many conventional engines had to have heavy flywheels added to smooth out power impulses and reduce vibration. Rotary engines gained a substantial power-to-weight ratio advantage by having no need for an added flywheel, like radial engines, rotaries were generally built with an odd number of cylinders, so that a consistent every-other-piston firing order could be maintained, to provide smooth running. Rotary engines with an number of cylinders were mostly of the two row type. Rotary and radial engines look strikingly similar when they are not running and can easily be confused, unlike the rotary engine, however, radial engines use a conventional rotating crankshaft in a fixed engine block. The Musee de lAir in Paris has on display a special and it alternates between rotary and radial modes to demonstrate the difference between the internal motions of the two types of engine. It is often asserted that rotary engines had no carburetor and hence power could only be reduced by cutting the ignition using a blip switch. This was almost literally true of the Monosoupape type, which took most of the air into the cylinder through the exhaust valve, thus the richness of the mixture in the cylinder could not be controlled via the crankcase intake. The throttle of a monosoupape provided only a limited degree of speed regulation, as opening it made the mixture too rich. Early models featured a form of variable valve timing in an attempt to give greater control. Most rotaries however, had normal inlet valves, so that the fuel was taken into the already mixed with air - as in a normal four-stroke engine. The pilot needed to set the throttle to the desired setting, after starting the engine with a known setting that allowed it to idle, the air valve was opened until maximum engine speed was obtained. Throttling a running back to reduce revs was possible by closing off the fuel valve to the required position while re-adjusting the fuel/air mixture to suit. This process was also tricky, so that throttling back, especially when landing, was accomplished by intermittently cutting the ignition using the blip switch. Cutting cylinders using ignition switches had the drawback of letting fuel continue to pass through the engine, oiling up the spark plugs, also, the raw oil-fuel mix could collect in the cowling

Hispano-Suiza 8
–
The Hispano-Suiza 8 was a water-cooled V8 SOHC aero engine introduced by Hispano-Suiza in 1914 and was the most commonly used engine in the aircraft of the Entente Powers during the First World War. The original Hispano-Suiza 8A was rated at 140 hp and the later Hispano-Suiza 8F reached 300 hp, hS-8 engines and variants produced by Hispano-Suiza and other companies under licence were built in twenty-one factories in Spain, France, Britain, Italy, and the U. S. When World War I began, the lines of the Barcelona based Hispano-Suiza automobile. Chief engineer Marc Birkigt led work on an engine based on his successful V8 automobile engine. The resulting engine, called the Hispano-Suiza 8A, made its first appearance in February 1915. The first 8A kept the standard configuration of Birkigts existing design, eight cylinders in 90° Vee configuration, a displacement of 11.76 litres, in spite of the similarities with the original design, the engine had been substantially refined. The crankshaft was machined from a piece of steel. The cylinders were cast aluminium with steel liners, aluminium parts were coated in vitreous enamel to reduce leakage. All parts subject to wear, and those critical for engine ignition were duplicated, spark plugs for dual ignition reliability, valve springs, magnetos, engine reliability and power to weight ratios were major problems in early aviation. The engine and its accessories weighed 185 kg, making it 40% lighter than an engine of equivalent power. The new engine was presented to the French Ministry of War in February 1915 and this was standard procedure for a new engine design to be admitted into military service. However, because of lobbying by French engine manufacturers, the Spanish made engine was ordered to undergo a bench test that no French made engine had yet passed, a 50-hour run at full speed. The HS-8A was therefore sent back to Chalais-Meudon on July 21,1915 and tested for 50 hours, rotary engines of increased power generally had increased weight, which in turn increased the already serious gyroscopic torque generated by the engines rotation. A further increase in torque was considered unacceptable, and the power to weight ratio of the new engines under development did not appeal to aircraft designers. French officials ordered production of the 8A to be started as soon as possible, the SPAD VII was the result of this requirement and would allow the Allies to regain air superiority over the Germans. 8100 kW, initial production and test engines, with few applications, 8Aa 110 kW at 2000 rpm, entered production in July 1915. Early HS-8A engines were plagued with problems which required further work and was the standard powerplant for early-production SPAD VIIs. The demand for the Hispano-Suiza engine was such that other manufacturers began producing it under licence, in France, Great Britain, Italy, total production of the HS-8Aa amounted to some 6,000 engines

Dunkirk
–
Dunkirk is a commune in the Nord department in northern France. It lies 10 kilometres from the Belgian border, the population of the city at the 2012 census was 90,995 inhabitants. The name of Dunkirk derives from West Flemish dun and kerke, nowadays, Dunkirk is the worlds northernmost Francophone city. About 960AD Count Baldwin III had a wall erected, in order to protect the settlement against Viking raids. The surrounding wetlands were drained and cultivated by the monks of nearby Bergues Abbey, the name Dunkirk was first mentioned in a tithe privilege of 27 May 1067, issued by Count Baldwin V of Flanders. Count Philip I brought further large tracts of marshland under cultivation, laid out first plans to build a Canal from Dunkirk to Bergues and vested the Dunkirkers with market rights. However, in the course of the Western Schism from 1378, English supporters of Pope Urban VI disembarked at Dunkirk, captured the city and they were ejected by King Charles VI of France, but left great devastations in and around the town. Upon the extinction of the Counts of Flanders with the death of Louis II in 1384, Flanders was acquired by the Burgundian, the fortifications were again enlarged, including the construction of a belfry daymark. As Maximilian was the son of Emperor Frederick III, all Flanders was immediately seized by King Louis XI of France. However, the defeated the French troops at the 1479 Battle of Guinegate. The area remained disputed between Spain, the United Netherlands, England and France. At the beginning of the Eighty Years War, Dunkirk was briefly in the hands of the Dutch rebels, Spanish forces under Duke Alexander Farnese of Parma re-established Spanish rule in 1583 and it became a base for the notorious Dunkirkers. The Dunkirkers briefly lost their home port when the city was conquered by the French in 1646, in 1658, as a result of the long war between France and Spain, it was captured after a siege by Franco-English forces following the battle of the Dunes. The city along with Fort-Mardyck was awarded to England in the peace the following year as agreed in the Franco-English alliance against Spain and it came under French rule when Charles II of England sold it to France for £320,000 on 17 October 1662. The French government developed the town as a fortified port, the towns existing defences were adapted to create ten bastions. The port was expanded in the 1670s by the construction of a basin that could hold up to thirty warships with a lock system to maintain water levels at low tide. The basin was linked to the sea by a channel dug through coastal sandbanks secured by two jetties and this work was completed by 1678. The jetties were defended a few years later by the construction of five forts, Château dEspérance, Château Vert, Grand Risban, Château Gaillard, an additional fort was built in 1701 called Fort Blanc

Submarine
–
A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability, the term most commonly refers to a large, crewed vessel. It is also used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine. The noun submarine evolved as a form of submarine boat, by naval tradition, submarines are usually referred to as boats rather than as ships. Although experimental submarines had been built before, submarine design took off during the 19th century, Submarines were first widely used during World War I, and now figure in many navies large and small. Civilian uses for submarines include marine science, salvage, exploration and facility inspection, Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or undersea cable repair. Submarines are also used in tourism, and for undersea archaeology, most large submarines consist of a cylindrical body with hemispherical ends and a vertical structure, usually located amidships, which houses communications and sensing devices as well as periscopes. In modern submarines, this structure is the sail in American usage, a conning tower was a feature of earlier designs, a separate pressure hull above the main body of the boat that allowed the use of shorter periscopes. There is a propeller at the rear, and various hydrodynamic control fins, smaller, deep-diving and specialty submarines may deviate significantly from this traditional layout. Submarines use diving planes and also change the amount of water, Submarines have one of the widest ranges of types and capabilities of any vessel. Submarines can work at greater depths than are survivable or practical for human divers, modern deep-diving submarines derive from the bathyscaphe, which in turn evolved from the diving bell. In 1578, the English mathematician William Bourne recorded in his book Inventions or Devises one of the first plans for an underwater navigation vehicle and its unclear whether he ever carried out his idea. The first submersible of whose construction there exists reliable information was designed and built in 1620 by Cornelis Drebbel and it was propelled by means of oars. By the mid-18th century, over a dozen patents for submarines/submersible boats had been granted in England, in 1747, Nathaniel Symons patented and built the first known working example of the use of a ballast tank for submersion. His design used leather bags that could fill with water to submerge the craft, a mechanism was used to twist the water out of the bags and cause the boat to resurface. In 1749, the Gentlemens Magazine reported that a design had initially been proposed by Giovanni Borelli in 1680. By this point of development, further improvement in design stagnated for over a century, until new industrial technologies for propulsion. The first military submarine was the Turtle, a hand-powered acorn-shaped device designed by the American David Bushnell to accommodate a single person and it was the first verified submarine capable of independent underwater operation and movement, and the first to use screws for propulsion

Portugal
–
Portugal, officially the Portuguese Republic, is a country on the Iberian Peninsula in Southwestern Europe. It is the westernmost country of mainland Europe, to the west and south it is bordered by the Atlantic Ocean and to the east and north by Spain. The Portugal–Spain border is 1,214 kilometres long and considered the longest uninterrupted border within the European Union, the republic also includes the Atlantic archipelagos of the Azores and Madeira, both autonomous regions with their own regional governments. The territory of modern Portugal has been settled, invaded. The Pre-Celts, Celts, Carthaginians and the Romans were followed by the invasions of the Visigothic, in 711 the Iberian Peninsula was invaded by the Moors, making Portugal part of Muslim Al Andalus. Portugal was born as result of the Christian Reconquista, and in 1139, Afonso Henriques was proclaimed King of Portugal, in the 15th and 16th centuries, Portugal established the first global empire, becoming one of the worlds major economic, political and military powers. Portugal monopolized the trade during this time, and the Portuguese Empire expanded with military campaigns led in Asia. After the 1910 revolution deposed the monarchy, the democratic but unstable Portuguese First Republic was established, democracy was restored after the Portuguese Colonial War and the Carnation Revolution in 1974. Shortly after, independence was granted to almost all its overseas territories, Portugal has left a profound cultural and architectural influence across the globe and a legacy of over 250 million Portuguese speakers today. Portugal is a country with a high-income advanced economy and a high living standard. It is the 5th most peaceful country in the world, maintaining a unitary semi-presidential republican form of government and it has the 18th highest Social Progress in the world, putting it ahead of other Western European countries like France, Spain and Italy. Portugal is a pioneer when it comes to drug decriminalization, as the nation decriminalized the possession of all drugs for use in 2001. The early history of Portugal is shared with the rest of the Iberian Peninsula located in South Western Europe, the name of Portugal derives from the joined Romano-Celtic name Portus Cale. Other influences include some 5th-century vestiges of Alan settlements, which were found in Alenquer, Coimbra, the region of present-day Portugal was inhabited by Neanderthals and then by Homo sapiens, who roamed the border-less region of the northern Iberian peninsula. These were subsistence societies that, although they did not establish prosperous settlements, neolithic Portugal experimented with domestication of herding animals, the raising of some cereal crops and fluvial or marine fishing. Chief among these tribes were the Calaicians or Gallaeci of Northern Portugal, the Lusitanians of central Portugal, the Celtici of Alentejo, a few small, semi-permanent, commercial coastal settlements were also founded in the Algarve region by Phoenicians-Carthaginians. Romans first invaded the Iberian Peninsula in 219 BC, during the last days of Julius Caesar, almost the entire peninsula had been annexed to the Roman Republic. The Carthaginians, Romes adversary in the Punic Wars, were expelled from their coastal colonies and it suffered a severe setback in 150 BC, when a rebellion began in the north

Portuguese Naval Aviation
–
It is more commonly known as Naval Aviation as it received various official designations throughout its service and its origins date back to 1917, when it was created has the air branch of the Navy. These two Navy officers — 1TEN Artur de Sacadura Cabral and GMAR AN António Joaquim Caseiro — underwent basic training at Chartres and flying boat flight training at Saint-Raphaël. Meanwhile, Navy personnel started receiving training and aircraft maintenance instruction at the school and abroad. On September 28,1917, the Navys Aviation Service was created with its personnel, material, the service was then installed at the Bom Sucesso Naval Air Station in the Lisbon docks.
