Aviation
–
Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word aviation was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb avier, itself derived from the Latin word avis and the suffix -ation. The modern age of aviation began with the first untethered human lighter-than-air flight on November 21,1783, the practicality of balloons was limited because they could only travel downwind. It was immediately recognized that a steerable, or dirigible, balloon was required, jean-Pierre Blanchard flew the first human-powered dirigible in 1784 and crossed the English Channel in one in 1785. Rigid airships became the first aircraft to transport passengers and cargo over great distances, the best known aircraft of this type were manufactured by the German Zeppelin company. The most successful Zeppelin was the Graf Zeppelin and it flew over one million miles, including an around-the-world flight in August 1929. However, the dominance of the Zeppelins over the airplanes of that period, the Golden Age of the airships ended on May 6,1937 when the Hindenburg caught fire, killing 36 people. The cause of the Hindenburg accident was blamed on the use of hydrogen instead of helium as the lift gas. An internal investigation by the manufacturer revealed the coating used to protect the material over the frame was highly flammable. Changes to the coating formulation reduced the risk of further Hindenburg type accidents, although there have been periodic initiatives to revive their use, airships have seen only niche application since that time. In 1799 Sir George Cayley set forth the concept of the airplane as a fixed-wing flying machine with separate systems for lift, propulsion. Seven years later, on 14 October 1897, Aders Avion III was tested without success in front of two officials from the French War ministry, the report on the trials was not publicized until 1910, as they had been a military secret. In November 1906 Ader claimed to have made a flight on 14 October 1897. Although widely believed at the time, these claims were later discredited, however, the most widely accepted date is December 17,1903 by the Wright brothers. The Wright brothers were the first to fly in a powered and controlled aircraft, previous flights were gliders or free flight, but the Wright brothers combined both, setting the new standard in aviation records. Aircraft began to transport people and cargo as designs grew larger, the Wright brothers took aloft the first passenger, Charles Furnas, one of their mechanics, on May 14,1908. By the beginning of World War II, many towns and cities had built airports, the war brought many innovations to aviation, including the first jet aircraft and the first liquid-fueled rockets. Manufacturers such as Cessna, Piper, and Beechcraft expanded production to provide aircraft for the new middle-class market

Military history of Iran
–
The Achaemenid Empire was the first of the Persian Empires to rule over significant portions of Greater Iran. The empire possessed a “national army” of roughly 120. 000-150.000 troops, the Persian army was divided into regiments of a thousand each, called hazarabam. Ten hazarabams formed a haivarabam, or division, the best known haivarabam were the Immortals, the Kings personal guard division. The smallest unit was the ten man dathaba, ten dathabas formed the hundred man sataba. The royal army used a system of uniforms to identify different units. A large variety of colors were used, some of the most common being yellow, purple, but this system was probably limited to native Persian troops and was not used for their numerous allies. The usual tactic employed by the Persians in the period of the empire, was to form a shield wall that archers could fire over. These troops were equipped with a large wicker shield called a spara. The bow was the preferred missile-weapon of the Persians, at maximum rate of fire a sparabara haivarabam of 10,000 men could launch approximately 100,000 arrows in a single minute and maintain this rate for a number of minutes. Then the Persian cavalry would move aside and attempt to harass the flanks of the enemy, defending against the Persian cavalry required the enemy infantry to congregate in dense static formations, which were ideal targets for the Persian archers. Even heavily armoured infantry like the Greek hoplites would suffer casualties in such conditions. Enemy infantry formations that scattered to reduce casualties from the volleys of Persian arrows, were exposed to a close-in shock assault by the Persian cavalry. Torn by the dilemma between exposure to a gradual attrition by the arrows or to being overwhelmed by a charge on their flanks. B) Good coordination between the cavalry and the infantry, c) An enemy inferior in mobility. Most Persian defeats can be attributed to one or more of these not being met. The Seleucid Empire was a Hellenistic successor state of Alexander the Greats dominion, including central Anatolia, the Levant, Mesopotamia, Persia, Turkmenistan, Pamir and it was the third native dynasty of ancient Iran. Parthia was the arch-enemy of the Roman Empire for nearly three centuries, after the Scythian-Parni nomads had settled in Parthia and built a small independent kingdom, they rose to power under king Mithridates the Great. Later, at the height of their power, Parthian influence reached as far as Ubar in Arabia, the nexus of the trade route

Argentine Navy
–
The Navy of the Argentine Republic or Argentine Navy is the navy of Argentina. It is one of the three branches of the Armed Forces of the Argentine Republic, together with the Army and the Air Force, each ship of the Argentine Navy is designated with the prefix ARA before its name. The Argentine Navy day is celebrated on May 17, anniversary of the victory achieved in 1814 in the Battle of Montevideo over the Spanish fleet during the war of Independence. The Argentine Navy was created in the aftermath of the May Revolution of May 25,1810, the navy was first created to support Manuel Belgrano in the Paraguay campaign, but it was sunk by ships from Montevideo, and did not take part in that conflict. Renewed conflicts with Montevideo led to the creation of a second fleet, as Buenos Aires had little maritime history, most men in the navy were from other nations, such as the Irish-born admiral William Brown, who directed the operation. As the cost of maintaining a navy was too high, most of the Argentine naval forces were composed of privateers, Brown led the Argentine navy in further naval conflicts at the War with Brazil and the Anglo-French blockade of the Río de la Plata. In the 1870s the Argentine Navy began modernizing itself, the most powerful ships at this time included the Italian-built Garibaldi and her sister ships, General Belgrano, Pueyrredón, and San Martín, each at over 6,000 tons. Three older ironclads, Almirante Brown, Independencia, and Libertad dated from the 1880s, the navys ships were built primarily in Italy, Britain, France, and Spain and were operated by over 600 officers and 7760 seamen. These were supported by a battalion of marines and an artillery battery, Argentina remained neutral in both world wars. In 1940, Argentinas navy was ranked the eighth most powerful in the world, a ten-year building programme costing $60 million had produced a force of 14,500 sailors and over a thousand officers. A naval air force was also in operation, in the postwar period, Naval Aviation and Marine Corps units were put under direct Navy command. With Brazil, Argentina is one of two South American countries to have operated two aircraft carriers, the ARA Independencia and ARA Veinticinco de Mayo, the Navy also took part in all military coups through the 20th century. During the last dictatorship, Navy personnel were involved in the Dirty War of the late 1970s in which thousands of people were kidnapped, tortured and killed by the forces of the Military Junta, the Naval Mechanics School, known as ESMA, was a notorious centre for torture. Among their more well-known victims were the Swedish teenager Dagmar Hagelin and French nuns, Alice Domon and this fleet was supported by several ELMA tankers and transports as well as two ice breakers/polar ships. New German MEKO class destroyers, corvettes and Thyssen-Nordseewerke submarines were still under construction at the time, despite leading the invasion of the Falkland Islands, in both strategic and tactical aspects the Argentine fleet played only a small part in the subsequent conflict with the Royal Navy. The ARA San Luis submarine also played a role, nearly sinking the frigate HMS Arrow on 10 May. The submarine ARA Santa Fe, after a resupply mission, was attacked and disabled off South Georgia. She was later scuttled by the British, also, the submarine force greatly reinforced their assets with the introduction of the Thyssen-Nordseewerke class

Brazil
–
Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the worlds fifth-largest country by area and population, it is the largest country to have Portuguese as an official language. Its Amazon River basin includes a vast tropical forest, home to wildlife, a variety of ecological systems. This unique environmental heritage makes Brazil one of 17 megadiverse countries, Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral, who claimed the area for the Portuguese Empire. Brazil remained a Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro, in 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal, Brazil and the Algarves. Independence was achieved in 1822 with the creation of the Empire of Brazil, a state governed under a constitutional monarchy. The ratification of the first constitution in 1824 led to the formation of a bicameral legislature, the country became a presidential republic in 1889 following a military coup détat. An authoritarian military junta came to power in 1964 and ruled until 1985, Brazils current constitution, formulated in 1988, defines it as a democratic federal republic. The federation is composed of the union of the Federal District, the 26 states, Brazils economy is the worlds ninth-largest by nominal GDP and seventh-largest by GDP as of 2015. A member of the BRICS group, Brazil until 2010 had one of the worlds fastest growing economies, with its economic reforms giving the country new international recognition. Brazils national development bank plays an important role for the economic growth. Brazil is a member of the United Nations, the G20, BRICS, Unasul, Mercosul, Organization of American States, Organization of Ibero-American States, CPLP. Brazil is a power in Latin America and a middle power in international affairs. One of the worlds major breadbaskets, Brazil has been the largest producer of coffee for the last 150 years and it is likely that the word Brazil comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil, with the word brasil commonly given the etymology red like an ember, formed from Latin brasa and the suffix -il. As brazilwood produces a red dye, it was highly valued by the European cloth industry and was the earliest commercially exploited product from Brazil. The popular appellation eclipsed and eventually supplanted the official Portuguese name, early sailors sometimes also called it the Land of Parrots. In the Guarani language, a language of Paraguay, Brazil is called Pindorama

Merchant vessel
–
A merchant vessel or trading vessel is a boat or ship that transports cargo or carries passengers for hire. This excludes pleasure craft that do not carry passengers for hire, most countries of the world operate fleets of merchant ships. However, due to the costs of operations, today these fleets are in many cases sailing under the flags of nations that specialize in providing manpower. Such flags are known as flags of convenience, currently, Liberia and Panama are particularly favoured. Ownership of the vessels can be by any country, however, the Greek-owned fleet is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world’s tonnage, during wars, merchant ships may be used as auxiliaries to the navies of their respective countries, and are called upon to deliver military personnel and materiel. The term commercial vessel is defined by the United States Coast Guard as any vessel engaged in trade or that carries passengers for hire. In English, Merchant Navy without further clarification is used to refer to the British Merchant Navy, general cargo ships include multi-purpose and project vessels and roll-on/roll-off cargo. A cargo ship or freighter is any sort of ship or vessel that carries cargo, goods, thousands of cargo carriers ply the worlds seas and oceans each year, they handle the bulk of international trade. Cargo ships are usually designed for the task, often being equipped with cranes and other mechanisms to load and unload. Dry cargo ships today are mainly bulk carriers and container ships, bulk carriers or bulkers are used for the transportation of homogeneous cargo such as coal, rubber, copra, tin, and wheat. Container ships are used for the carriage of miscellaneous goods, a bulk carrier is an ocean-going vessel used to transport bulk cargo items such as iron ore, bauxite, coal, cement, grain and similar cargo. Bulk carriers can be recognized by large box-like hatches on deck, the dimensions of bulk carriers are often determined by the ports and sea routes that they need to serve, and by the maximum width of the Panama Canal. Most lakes are too small to accommodate bulk carriers, but a large fleet of lake freighters has been plying the Great Lakes, container ships are cargo ships that carry all of their load in truck-size containers, in a technique called containerization. They form a common means of commercial freight transport. A tanker is a designed to transport liquids in bulk. Tankers can range in size from several hundred tons, designed to serve small harbours and coastal settlements, to several hundred thousand tons, gas Carriers such as LNG carriers as they are typically known, are a relatively rare tanker designed to carry liquefied natural gas. It has a deadweight of 565 thousand metric tons and length of about 458 meters, the use of such large ships is in fact very unprofitable, due to the inability to operate them at full cargo capacity, hence, the production of supertankers has currently ceased

Aircraft carrier
–
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Aircraft carriers are expensive to build and are critical assets, there is no single definition of an aircraft carrier, and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said, To put it simply, as of April 2017, there are 37 active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered fleet carriers, the largest carriers in the world, the Royal Navy of Great Britain is building two 280-m / 920-ft carriers, the Queen Elizabeth, and the Prince of Wales scheduled to go into service in 2020-2023. These are the largest carriers capable of fast speeds, by comparison, escort carriers were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried, most were built from mercantile hulls or, in the case of merchant aircraft carriers, were bulk cargo ships with a flight deck added on top. Light aircraft carriers were fast enough to operate with the main fleet, three nations currently operate carriers of this type, ten by the United States, and one each by France and Brazil for a total of twelve in service. Short take-off but arrested-recovery, these carriers are generally limited to carrying lighter fixed-wing aircraft with more limited payloads, currently, Russia, China, and India possess commissioned carriers of this type. Short take-off vertical-landing, limited to carrying STOVL aircraft and this type of aircraft carrier is currently in service with Italy. Some also count the nine US amphibious assault ships in their secondary light carrier role boosting the total to thirteen. Helicopter carrier, Helicopter carriers have an appearance to other aircraft carriers. Some are designed for addition of, or may include, a ski jump ramp allowing for STOVL operations or may have a ski jump installed before retirement of STOVL aircraft. In the past, some conventional carriers were converted and called commando carriers by the Royal Navy, some helicopter carriers with a resistant flight surface can operate STOVL jets. Currently the majority of carriers, but not all, are classified as amphibious assault ships. The US has nine of this type, France and Japan three, Australia two, the UK one, the Republic of Korea one and Spain one, the US and Spains amphibious assault ships operate STOVL jets in normal deployment. Supercarrier Fleet carrier Light aircraft carrier Escort carrier Several systems of identification symbol for aircraft carriers, two months later, on 18 January 1911, Ely landed his Curtiss pusher airplane on a platform on the armored cruiser USS Pennsylvania anchored in San Francisco Bay

Latin America
–
Latin America is a group of countries and dependencies in the Americas where Romance languages are predominant. It is therefore broader than the terms Ibero-America or Hispanic America—though it usually excludes French Canada and it has an area of approximately 19,197,000 km2, almost 13% of the Earths land surface area. As of 2015, its population was estimated at more than 626 million and in 2014, Latin America had a combined nominal GDP of 5,573,397 million USD and a GDP PPP of 7,531,585 million USD. The term Latin America was first used in 1861 in La revue des races Latines, a further investigation of the concept of Latin America is by Michel Gobat in the American Historical Review. The term was first used in Paris in an 1856 conference by the Chilean politician Francisco Bilbao and this term was also used in 1861 by French scholars in La revue des races Latines, a magazine dedicated to the Pan-Latinism movement. Latin America is, therefore, defined as all parts of the Americas that were once part of the Spanish. By this definition, Latin America is coterminous with Ibero-America and this definition emphasizes a similar socioeconomic history of the region, which was characterized by formal or informal colonialism, rather than cultural aspects. As such, some sources avoid this oversimplification by using the phrase Latin America, the distinction between Latin America and Anglo-America is a convention based on the predominant languages in the Americas by which Romance-language and English-speaking cultures are distinguished. Latin America can be subdivided into several subregions based on geography, politics, demographics and it may be subdivided on linguistic grounds into Hispanic America, Portuguese America and French America. *, Not a sovereign state The concept of Latin America has been criticized by a number of intellectuals, the earliest known settlement was identified at Monte Verde, near Puerto Montt in Southern Chile. Its occupation dates to some 14,000 years ago and there is disputed evidence of even earlier occupation. Over the course of millennia, people spread to all parts of the continents, by the first millennium CE, South Americas vast rainforests, mountains, plains and coasts were the home of tens of millions of people. Some groups formed more permanent settlements such as the Chibcha and the Tairona groups and these groups are in the circum Caribbean region. The Chibchas of Colombia, the Quechuas and Aymaras of Bolivia, the region was home to many indigenous peoples and advanced civilizations, including the Aztecs, Toltecs, Maya, and Inca. The Aztec empire was ultimately the most powerful civilization known throughout the Americas, with the arrival of the Europeans following Christopher Columbus voyages, the indigenous elites, such as the Incas and Aztecs, lost power to the heavy European invasion. Hernándo Cortés seized the Aztec elites power with the help of local groups who had favored the Aztec elite, epidemics of diseases brought by the Europeans, such as smallpox and measles, wiped out a large portion of the indigenous population. Historians cannot determine the number of natives who died due to European diseases, due to the lack of written records, specific numbers are hard to verify. Many of the survivors were forced to work in European plantations, intermixing between the indigenous peoples and the European colonists was very common, and, by the end of the colonial period, people of mixed ancestry formed majorities in several colonies

London
–
London /ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain and it was founded by the Romans, who named it Londinium. Londons ancient core, the City of London, largely retains its 1. 12-square-mile medieval boundaries. London is a global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism. It is crowned as the worlds largest financial centre and has the fifth- or sixth-largest metropolitan area GDP in the world, London is a world cultural capital. It is the worlds most-visited city as measured by international arrivals and has the worlds largest city airport system measured by passenger traffic, London is the worlds leading investment destination, hosting more international retailers and ultra high-net-worth individuals than any other city. Londons universities form the largest concentration of education institutes in Europe. In 2012, London became the first city to have hosted the modern Summer Olympic Games three times, London has a diverse range of people and cultures, and more than 300 languages are spoken in the region. Its estimated mid-2015 municipal population was 8,673,713, the largest of any city in the European Union, Londons urban area is the second most populous in the EU, after Paris, with 9,787,426 inhabitants at the 2011 census. The citys metropolitan area is the most populous in the EU with 13,879,757 inhabitants, the city-region therefore has a similar land area and population to that of the New York metropolitan area. London was the worlds most populous city from around 1831 to 1925, Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Pauls Cathedral, Tower Bridge, Trafalgar Square, and The Shard. The London Underground is the oldest underground railway network in the world, the etymology of London is uncertain. It is an ancient name, found in sources from the 2nd century and it is recorded c.121 as Londinium, which points to Romano-British origin, and hand-written Roman tablets recovered in the city originating from AD 65/70-80 include the word Londinio. The earliest attempted explanation, now disregarded, is attributed to Geoffrey of Monmouth in Historia Regum Britanniae and this had it that the name originated from a supposed King Lud, who had allegedly taken over the city and named it Kaerlud. From 1898, it was accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos. The ultimate difficulty lies in reconciling the Latin form Londinium with the modern Welsh Llundain, which should demand a form *lōndinion, from earlier *loundiniom. The possibility cannot be ruled out that the Welsh name was borrowed back in from English at a later date, and thus cannot be used as a basis from which to reconstruct the original name. Until 1889, the name London officially applied only to the City of London, two recent discoveries indicate probable very early settlements near the Thames in the London area

Paris
–
Paris is the capital and most populous city of France. It has an area of 105 square kilometres and a population of 2,229,621 in 2013 within its administrative limits, the agglomeration has grown well beyond the citys administrative limits. By the 17th century, Paris was one of Europes major centres of finance, commerce, fashion, science, and the arts, and it retains that position still today. The aire urbaine de Paris, a measure of area, spans most of the Île-de-France region and has a population of 12,405,426. It is therefore the second largest metropolitan area in the European Union after London, the Metropole of Grand Paris was created in 2016, combining the commune and its nearest suburbs into a single area for economic and environmental co-operation. Grand Paris covers 814 square kilometres and has a population of 7 million persons, the Paris Region had a GDP of €624 billion in 2012, accounting for 30.0 percent of the GDP of France and ranking it as one of the wealthiest regions in Europe. The city is also a rail, highway, and air-transport hub served by two international airports, Paris-Charles de Gaulle and Paris-Orly. Opened in 1900, the subway system, the Paris Métro. It is the second busiest metro system in Europe after Moscow Metro, notably, Paris Gare du Nord is the busiest railway station in the world outside of Japan, with 262 millions passengers in 2015. In 2015, Paris received 22.2 million visitors, making it one of the top tourist destinations. The association football club Paris Saint-Germain and the rugby union club Stade Français are based in Paris, the 80, 000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the neighbouring commune of Saint-Denis. Paris hosts the annual French Open Grand Slam tennis tournament on the red clay of Roland Garros, Paris hosted the 1900 and 1924 Summer Olympics and is bidding to host the 2024 Summer Olympics. The name Paris is derived from its inhabitants, the Celtic Parisii tribe. Thus, though written the same, the name is not related to the Paris of Greek mythology. In the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps, since the late 19th century, Paris has also been known as Panam in French slang. Inhabitants are known in English as Parisians and in French as Parisiens and they are also pejoratively called Parigots. The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC. One of the areas major north-south trade routes crossed the Seine on the île de la Cité, this place of land and water trade routes gradually became a town

Imperial Japanese Navy
–
The Imperial Japanese Navy was the navy of the Empire of Japan from 1868 until 1945, when it was dissolved following Japans defeat and surrender in World War II. The Japan Maritime Self-Defense Force was formed after the dissolution of the IJN, the Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy. It was supported by the Imperial Japanese Navy Air Service for aircraft and it was the primary opponent of the Western Allies in the Pacific War. This eventually led to the Meiji Restoration, accompanying the re-ascendance of the Emperor came a period of frantic modernization and industrialization. Following the attempts at Mongol invasions of Japan by Kubilai Khan in 1274 and 1281, Japan undertook major naval building efforts in the 16th century, during the Warring States period, when feudal rulers vying for supremacy built vast coastal navies of several hundred ships. Around that time Japan may have developed one of the first ironclad warships when Oda Nobunaga, in 1588 Toyotomi Hideyoshi issued a ban on Wakō piracy, the pirates then became vassals of Hideyoshi, and comprised the naval force used in the Japanese invasion of Korea. Japan built her first large ocean-going warships in the beginning of the 17th century, from 1604 the Bakufu also commissioned about 350 Red seal ships, usually armed and incorporating some Western technologies, mainly for Southeast Asian trade. For more than 200 years, beginning in the 1640s, the Japanese policy of seclusion forbade contacts with the outside world and prohibited the construction of ocean-going ships on pain of death. Contacts were maintained, however, with the Dutch through the port of Nagasaki, the Chinese also through Nagasaki and the Ryukyus and Korea through intermediaries with Tsushima. Apart from Dutch trade ships no other Western vessels were allowed to enter Japanese ports, an exception was during the Napoleonic wars. However frictions with foreign ships started from the beginning of the 19th century, the Nagasaki Harbour Incident involving the HMS Phaeton in 1808 and other subsequent incidents in the following decades led to the Shogunate to enact an edict to repel foreign vessels. Western ships which were increasing their presence around Japan due to whaling, the shogunate also began to strengthen the nations coastal defenses. Numerous attempts to open Japan ended in failure in part to Japanese resistance, during 1853 and 1854, American warships under the command of Commodore Matthew Perry entered Edo Bay and made demonstrations of force requesting trade negotiations. After two hundred years of seclusion the 1854 Convention of Kanagawa led to the opening of Japan to international trade and this was soon followed by the 1858 Treaty of Amity and Commerce and treaties with other powers. In 1855, with Dutch assistance, the Shogunate acquired its first steam warship, Kankō Maru, samurai such as the future Admiral Enomoto Takeaki were sent by the Shogunate to study in the Netherlands for several years. In 1859 the Naval Training Center relocated to Tsukiji in Tokyo, in 1857 the Shogunate acquired its first screw-driven steam warship Kanrin Maru and used it as an escort for the 1860 Japanese delegation to the United States. In 1865 the French naval engineer Léonce Verny was hired to build Japans first modern naval arsenals, at Yokosuka, in 1867–1868 a British Naval mission headed by Commander Richard Tracey went to Japan to assist the development of the Japanese Navy and to organize the naval school of Tsukiji. The Shogunate also allowed and then ordered various domains to purchase warships and to develop naval fleets, Satsuma, a naval center had been set up by the Satsuma domain in Kagoshima, students were sent abroad for training and a number of ships were acquired

Rigid airship
–
Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschifbau Zeppelin company. Rigid airships were produced and relatively successfully employed from the beginning of the 1900s to the end of the 1930s, Rigid airships consist of a structural framework usually covered in doped fabric containing a number of gasbags or cells containing a lifting gas. The noble gas helium was used by American airships in the 1920s and 30s and is used in all modern airships, similarly, by flying nose-down down-force can be generated, this may be done to prevent the airship rising above its pressure height. Typically airships start a flight with their gasbags inflated to about 95% capacity, by 1874 several people had conceived of a rigid dirigible. The Frenchman Joseph Spiess had patented a rigid airship design in 1873, Count Zeppelin had outlined his thoughts of a rigid airship in diary entries from 25 March 1874 through to 1890 when he resigned from the military. David Schwarz had thought about building an airship in the 1880s and had started design work in 1891. It was not until after Schwarzs death in 1897 that his airship, built with help from the industrialist Carl Berg. With Bergs aluminium, Zeppelin was able to start building his first airship in 1899, ferdinand von Zeppelin completed his first airship, the LZ1 in July 1900. Constructed in a shed on Lake Constance, it was 128.02 m long,11.73 m in diameter with a volume of 11,298 m3 and was powered by two 11 kW Daimler engines. The first flight, lasting 20 minutes, was made on 2 July, after repairs and modifications two further flights were made in October 1900. These experiments failed to attract any investors, and Count Zeppelin did not complete his design, LZ2. This made only a flight on 17 January 1906. After both engines failed it made a landing in the Allgäu mountains, where a storm subsequently damaged it beyond repair. A similar design, the LZ3 was soon completed and this performed well enough to interest the German Army, but they required an airship capable of flying for 24 hours. This was beyond the capability of LZ3, so a larger craft and this was 136 m long,12.95 m in diameter and powered by two Daimler engines delivering a total of 156 kW. LZ4 first flew on 20 June 1908, and on 1 July made a spectacular 12 hour cross-country flight during which it was flown over Switzerland to Zürich, the 24-hour trial was started on 4 August, but was interrupted by the failure of one of the engines. It was moored near Echterdingen in order to make repairs but a storm arose and it away from its moorings, was blown into some trees. The disaster took place in front of an estimated 40 to 50 thousand spectators, seven were operated by DELAG, the first airline in the world

Combined Fleet
–
For the Carrier Striking Task Force, see Kido Butai. The Combined Fleet was the main ocean-going component of the Imperial Japanese Navy, the Combined Fleet was formally created for the first time on 18 July 1894 by the merger of the Standing Fleet and the Western Fleet. The Standing Fleet contained the navys most modern and combat-capable warships, the Western Fleet was a reserve force consisting primarily of obsolete ships deemed unsuitable for front-line combat operations, but still suitable for commerce protection and coastal defense. Vice-admiral Itoh Sukeyuki was appointed the first Commander-in-Chief of the Combined Fleet. for the duration of the first Sino-Japanese War against China, the Combined Fleet was re-formed during the Russo-Japanese War of 1904–05 to provide a unified overall command for the three separate fleets in the Imperial Japanese Navy. The IJN 1st Fleet was the battleship force, which formed the backbone of the navy and was intended to be used in a traditional line-of-battle showdown with an equivalent enemy battleship fleet. The IJN 2nd Fleet was a fast, mobile force with armored cruisers. The IJN 3rd Fleet was primarily a reserve fleet of obsolete vessels considered too weak for front-line combat service, admiral Togo Heihachiro was commander-in-chief of the Combined Fleet during the Russo-Japanese War. The Combined Fleet was not maintained as a permanent organization, but was created when necessary during fleet maneuvers or when called for by extraordinary circumstances. Thus, during the period from 1905–1924, the Combined Fleet was created only sporadically as the occasion or circumstances dictated, and disbanded immediately afterwards. As this was not intended to be permanent and since the commander of IJN 1st Fleet concurrently directed the Combined Fleet, from 1933, with the Manchurian Incident and the increasing tension with China, a permanent HQ staff for the Combined Fleet was established. By the late 1930s, it included most of Japans warships—only the base units, the Special Naval Landing Forces, the Combined Fleet came under direct command of the Imperial General Headquarters in 1937. With the start of the Pacific War with the attack on Pearl Harbor carried out by the Combined Fleets Kido Butai and it comprised the battleships, aircraft carriers, aircraft, and the components that made up the main fighting strength of the IJN. It was first mobilized on the whole for the Battle of Midway, after the devastating carrier losses at Midway and in the Solomon Islands campaign, the navy re-organized into a number of Area Fleets for local operational control of various geographic zones. The Combined Fleet then evolved into more of an administrative organization, in the resultant Battle of the Philippine Sea and the Battle of Leyte Gulf the Japanese fleet was decimated. The remnants of the Combined Fleet fled to Okinawa, but further operations were hindered by lack of fuel, by the time of the final suicide mission of the battleship Yamato in Operation Ten-Go, the Combined Fleet had ceased to exist as an effective combat force. The Combined Fleet was formally dissolved on 10 October 1945, commander in chief Chief of staff DAlbas, Andrieu.

Military exercise
–
A military exercise or war game is the employment of military resources in training for military operations, either exploring the effects of warfare or testing strategies without actual combat. This also serves the purpose of ensuring the readiness of garrisoned or deployable forces prior to deployment from home base / home station. Exercises in the 20th and 21st centuries have often identified by a unique codename in the same manner as military contingency operations. The more typically thought of exercise is the exercise, or the full-scale rehearsal of military maneuvers as practice for warfare. In a field exercise or fleet exercise, the two sides in the battle are typically called red and blue, to avoid naming a particular adversary. This naming convention originates with the inventors of the table-top war-game, a Command Post Exercise typically focuses on the battle readiness of staffs such as a particular Unified Combatant Command or one of its components at any level. It may run in parallel with an FTX or its equivalent, other types of exercise include the TEWT, also known as a sand table, map or cloth model exercise. This type of exercise allows commanders to manipulate models through possible scenarios in military planning and this is also called warfare simulation, or in some instances a virtual battlefield and in the past has been described as wargames. Said forces may be different branches of the forces from one country or may be armed forces from different countries. These latter events incorporating multiple nations have often referred to as NATO exercises, Coalition exercises, Bilateral exercises, Multilateral exercises. The modern use of military exercises grew out of the military need to study warfare, during the age of Kabinettskriege, Frederick the Great, King of Prussia from 1740 to 1786, put together his armies as a well-oiled clockwork mechanism whose components were robot-like warriors. No individual initiative was allowed to Fredericks soldiers, their role was to cooperate in the creation of walls of projectiles through synchronized firepower. This was in the pursuit of an effective army. Disciplined troops should respond predictably, allowing study to be confined to maneuvers and these first wargames were played with dice which represented friction, or the intrusion of less than ideal circumstances during a real war. 21st century militaries still use wargames to simulate future wars and model their reaction, according to Manuel de Landa, after World War II the Command, Control and Communications was transferred from the military staff to the RAND Corporation, the first think tank. Von Neumann was employed by the RAND Corporation, and his theory was used in wargames to model nuclear dissuasion during the Cold War. Thus, the US nuclear strategy was defined using wargames, SAM representing the US, early game theory included only zero-sum games, which means that when one player won, the other automatically lost. Thus, betrayal was considered as the most rational thing to do and this modelization gave the basis for the massive retaliation nuclear doctrine

Tokyo Bay
–
Tokyo Bay is a bay located in the southern Kantō region of Japan, and spans the coasts of Tokyo, Kanagawa Prefecture, and Chiba Prefecture. Tokyo Bay is connected to the Pacific Ocean by the Uraga Channel and its old name was Edo Bay. The Tokyo Bay region is both the most populous and largest industrialized area in Japan, in ancient times, Japanese knew Tokyo Bay as the uchi-umi or inner sea. By the Azuchi-Momoyama period the area had become known as Edo Bay, the bay took its present name of Tokyo Bay in modern times, after the Imperial court moved to Edo and renamed that city as Tokyo in 1868. Tokyo Bay juts prominently into the Kantō Plain and it is surrounded by the Bōsō Peninsula in Chiba Prefecture to the east and the Miura Peninsula in Kanagawa Prefecture to the west. The shore of Tokyo Bay consists of a plateau and is subject to rapid marine erosion. Sediments on the shore of the bay make for a smooth, in a narrow sense, Tokyo Bay is the area north of the straight line from Cape Kannon on the west of Miura Peninsula to Cape Futtsu on the east Bōsō Peninsula. This area covers about 922 square kilometres, in a broader sense, Tokyo Bay includes the Uraga Channel. By this definition the bay opens from a north of the straight line from Cape Tsurugisaki on the east of Miura Peninsula to Cape Sunosaki on the west of the Boso Peninsula. This area covers about 1,100 square kilometres, the area of Tokyo Bay combined with the Uraga Channel covers 1,500 square kilometres. The shoal between Cape Futtsu in Chiba Prefecture and Cape Honmaku in Yokohama is known as Nakanose, and has a depth of 20 metres, north of this area the bay has a depth of 40 metres and an uncomplicated submarine topography. Areas south of Nakanose are significantly deeper moving towards the Pacific Ocean, the only natural island in Tokyo Bay is Sarushima at Yokosuka, Kanagawa Prefecture. Sarushima was one of the locations fortified with coastal artillery during the Bakumatsu period and was incorporated into the Tokyo Bay Fortress during the Meiji period. The Imperial Japanese Navy maintained a station on the island until the end of World War II. The island is now uninhabited and is a marine park, many artificial islands were built as naval fortifications in the Meiji and Taishō period. After World War II these islands were converted to residential or recreational use, Odaiba, also known as Daiba, was one of six artificial islands constructed in 1853 as a fortification to protect the Tokugawa shogunate at Edo, and was known as the Shinagawa Daiba. After World War II Odaiba was incorporated into Tokyo and redeveloped for commercial and recreational use, after World War II Yumenoshima was planned as a solution to dispose of the large quantities of garbage from the Tokyo Metropolitan Area. The island was constructed between 1957 and 1967 and hosts numerous recreational facilities, hakkei Island, formerly Landfill Number 14, was constructed in 1985 and is home to Yokohama Hakkeijima Sea Paradise

Torpedo
–
Historically, it was called an automotive, automobile, locomotive or fish torpedo, colloquially called a fish. The term torpedo was originally employed for a variety of devices, from about 1900, torpedo has been used strictly to designate an underwater self-propelled weapon. Todays torpedoes can be divided into lightweight and heavyweight classes, and into straight-running, autonomous homers and they can be launched from a variety of platforms. The word torpedo comes from the name of a genus of rays in the order Torpediniformes. In naval usage, the American Robert Fulton introduced the name to refer to a gunpowder charge used by his French submarine Nautilus to demonstrate that it could sink warships. The concept of a torpedo existed many centuries before it was successfully developed. In 1275, Hasan al-Rammah described. an egg which moves itself, in modern language, a torpedo is an underwater self-propelled explosive, —but historically, the term also applied to primitive naval mines. These were used on an ad hoc basis during the modern period up to the late 19th century. An early submarine, the Turtle, attempted to lay a bomb with a fuse on the hull of HMS Eagle during the American Revolutionary War. In the early 1800s, the American inventor Robert Fulton, while in France and he coined the term torpedo in reference to the explosive charges he outfitted his submarine Nautilus. However, both the French and the Dutch governments were uninterested in the submarine, Fulton then concentrated on developing the torpedo independent of a submarine deployment. However, the British government refused to purchase the invention, stating they did not wish to introduce into naval warfare a system that would give advantage to weaker maritime nations. Fulton carried out a demonstration for the US government on 20 July 1807. Further development languished as Fulton focused on his steam-boat matters, during the War of 1812, torpedoes were employed in attempts to destroy British vessels and protect American harbors. In fact a submarine deployed torpedo was used in an attempt to destroy HMS Ramillies while in New Londons harbor. Hardy to warn the Americans to cease efforts with the use of any boat in this cruel and unheard-of warfare. Torpedoes were used by the Russian Empire during the Crimean War in 1855 against British warships in the Gulf of Finland and they used an early form of chemical detonator. During the American Civil War, the torpedo was used for what is today called a contact mine

Spanish Navy
–
The Spanish Navy, is the maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world. Reform under the Bourbon dynasty improved its logistical and military capacity in the 18th century, currently, the Spanish Armada is the third largest navy in Europe, after the British Royal Navy and the French Navy, and the sixth in the world ranking. The main bases of the Spanish Navy are located in Rota, Ferrol, San Fernando, the roots of the modern Spanish navy date back to before the unification of Spain. By the late Middle Ages, the two kingdoms that would later combine to form Spain, Aragon and Castile, had developed powerful fleets. Aragon possessed the third largest navy in the late medieval Mediterranean, although its capabilities were exceeded by those of Venice, in 1402, a Castilian expedition led by Juan de Bethencourt conquered the Canary Islands for Henry III of Castile. In the 15th century, Castile entered into a race of exploration with Portugal, in 1492, two caravels and a carrack, commanded by Christopher Columbus, arrived in America, on an expedition that sought a westward oceanic passage across the Atlantic, to the Far East. This began the era of trade routes, pioneered by the Spanish in the seas to the west of Europe. The navy also carried explorers to the North American mainland, including Juan Ponce de León and Álvarez de Pineda, in 1519, Spain sent out the first expedition of world circumnavigation in history, which was put in the charge of the Portuguese Commander Ferdinand Magellan. Following the death of Magellan in the Philippines, the expedition was completed under the command of Juan Sebastián Elcano in 1522, for two and a half centuries, the Manila galleons operated across the Pacific linking Manila and Acapulco. Until the early 17th century, the Pacific Ocean, aside from the Marianas and Caroline Islands, several naval expeditions also discovered the Tuvalu archipelago, the Marquesas, the Solomon Islands and New Guinea in the South Pacific. In the quest for Terra Australis, Spanish explorers in the 17th century also discovered the Pitcairn, most significantly, from 1565 Spanish fleets explored and colonised the Philippine archipelago, the Spanish East Indies. This arrangement continued until superseded by the decline of galley warfare during the 17th century, most notable of these attacks was the Battle of Gibraltar in 1607, in which a Dutch squadron destroyed a fleet of galleons at anchor in the confines of the bay. This naval war took on a dimension with actions in the Caribbean. In the 1580s, the conflict in the Netherlands drew England into war with Spain, the effort to neutralise this threat led to a disastrous attempt to invade England in 1588. This defeat led to a reform of fleet operations, the navy at this time was not a single operation but consisted of various fleets, made up mainly of armed merchantmen with escorts of royal ships. The Armada fiasco marked a point in naval warfare, where gunnery was now more important than ramming and boarding. During the 1590s, the expansion of these allowed a great increase in the overseas trade and massive increase in the importation of luxuries. Port defences at Cadiz were upgraded and all attempts to repeat the attack in the following centuries would fail, meanwhile, Spanish ships were able to step up operations in the English Channel, the North Sea and towards Ireland

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Airship
–
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from large gas bags filled with a gas that is less dense than the surrounding air. In early dirigibles, the gas used was hydrogen, due to its high lifting capacity. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, significant amounts were first discovered in the United States and for a while helium was only used for airships by the United States. Most airships built since the 1960s have used helium, though some have used hot air, the envelope of an airship may form a single gas bag, or may contain a number of internal gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation, the main types of airship are non-rigid, semi-rigid, and rigid. Non-rigid airships, often called blimps, rely on internal pressure to maintain the shape of the airship, semi-rigid airships maintain the envelope shape by internal pressure, but have some form of supporting structure, such as a fixed keel, attached to it. Rigid airships have a structural framework which maintains the shape and carries all structural loads. Rigid airships were first flown by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded, as a result, rigid airships are called zeppelins. S. Navy helium-filled rigids, the USS Akron and USS Macon respectively, during the pioneer years of aeronautics, terms such as airship, air-ship, air ship and ship of the air meant any kind of navigable or dirigible flying machine. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. Nowadays the term airship is used only for powered, dirigible balloons, semirigid architecture is the more recent and the late appearance is caused by both advancements about deformable structures and exigiency of reducing weight and volume of the airships. They have a structure that ensure to keep the shape jointly with overpressure of the gas envelope. An aerostat is an aircraft which remain aloft using buoyancy or static lift, Airships are a type of aerostat. The term aerostat has also used to indicate a tethered or moored balloon as opposed to a free-floating balloon. A blimp is a non-rigid aerostat, in American usage it refers specifically to a non-rigid type of dirigible balloon or airship. In British usage it refers to any non-rigid aerostat, including balloons and other kite balloons, having a streamlined shape. The initials LZ, for Luftschiff Zeppelin, usually prefixed their crafts serial identifiers, streamlined Parsifal-shaped rigid airships are usually referred to as Zeppelin, because of the fame that this company has acquired due to the number of airships it produced

Balloon
–
A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern day balloons are made from such as rubber, latex, polychloroprene, or a nylon fabric. Some early balloons were made of dried animal bladders, such as the pig bladder, some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloons properties, including its low density and low cost, have led to a range of applications. The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases, Balloon Decorating Balloons are used for decorating birthday parties, weddings, corporate functions, school events, and for other festive gatherings. The artists who use the round balloons to build are called stackers, the most common types of balloon decor include arches, columns, centerpieces, balloon drops, sculptures, and balloon bouquets. Party balloons are made of a natural latex tapped from rubber trees. The rubbers elasticity makes the volume adjustable, often the term Party Balloon will refer to a twisting balloon or pencil balloon. These balloons are manipulated to create shapes and figures for parties and events, filling the balloon with air can be done with the mouth, a manual or electric inflater, or with a source of compressed gas. When rubber or plastic balloons are filled with helium so that they float, they retain their buoyancy for only a day or so. The enclosed helium atoms escape through pores in the latex which are larger than the helium atoms. Balloons filled with air usually hold their size and shape much longer, even a perfect rubber balloon eventually loses gas to the outside. The process by which a substance or solute migrates from a region of high concentration, through a barrier or membrane, to a region of lower concentration is called diffusion. The inside of balloons can be treated with a gel which coats the inside of the balloon to reduce the helium leakage. Beginning in the late 1970s, some more expensive foil balloons made of thin, unstretchable and these balloons have attractive shiny reflective surfaces and are often printed with color pictures and patterns for gifts and parties. The most important attribute of metallised nylon for balloons is its lightweight, increasing buoyancy, foil balloons have been criticized for interfering with power lines. Balloon artists are entertainers who twist and tie inflated tubular balloons into sculptures, the balloons used for sculpture are made of extra-stretchy rubber so that they can be twisted and tied without bursting. Since the pressure required to inflate a balloon is inversely proportional to the diameter of the balloon, a pump is usually used to inflate these balloons

Seaplane
–
A seaplane is a powered fixed-wing aircraft capable of taking off and landing on water. Seaplanes that can take off and land on airfields are in a subclass called amphibious aircraft. Their use gradually tailed off after World War II, partially because of the investments in airports during the war, the word seaplane is used to describe two types of air/water vehicles, the floatplane and the flying boat. A floatplane has slender pontoons, or floats, mounted under the fuselage, two floats are common, but other configurations are possible. Only the floats of a floatplane normally come into contact with water, some small land aircraft can be modified to become float planes, and in general, floatplanes are small aircraft. Floatplanes are limited by their inability to handle wave heights typically greater than 12 inches and these floats add to the empty weight of the airplane and to the drag coefficient, resulting in reduced payload capacity, slower rate of climb, and slower cruise speed. Most flying boats have small floats mounted on their wings to keep them stable, not all small seaplanes have been floatplanes, but most large seaplanes have been flying boats, with their great weight supported by their hulls. The term seaplane is used by some instead of floatplane and this is the standard British usage. This article treats both flying boats and floatplanes as types of seaplane, in the US fashion, an amphibious aircraft can take off and land both on conventional runways and water. A true seaplane can only take off and land on water, there are amphibious flying boats and amphibious floatplanes, as well as some hybrid designs, e. g. floatplanes with retractable floats. Modern production seaplanes are typically light aircraft, amphibious, and of a floatplane design, 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 United States. On 28 March 1910, Frenchman Henri Fabre 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

USS Patoka (AO-9)
–
USS Patoka was a fleet oiler made famous as a tender for the airships Shenandoah, Los Angeles and Akron. It was also notable in that its height figured prominently in the design of Rainbow Bridge in Texas. Named for the Patoka River, Patoka was laid down on 17 December 1918 by the Newport News Shipbuilding and Dry Dock Company of Newport News, Virginia and launched on 26 July 1919. Acquired by the Navy from the USSB on 3 September 1919 and she returned to Port Arthur for more oil and got under way on 9 January 1920 for the Adriatic Sea, arriving at Split on 12 February. Returning to the United States in April Patoka went back to the Near East and this work by the Norfolk Navy Yard was completed shortly after 1 July 1924. Patoka retained her classification of AO–9, Patoka engaged in a short series of mooring experiments with the Shenandoah, which had reported to the Commander, Scouting Fleet, for duty on 1 August 1924. The first successful mooring was made on 8 August 1924, during 1925 Patoka operated with both Shenandoah and Los Angeles in demonstrating the mobility of airships, and in reducing the number of ground personnel required to handle them. A projected polar flight by Shenandoah, using Patoka as her base of operations, was cancelled when the airship was lost in a storm on 3 September 1925, on 10 November 1939 Patoka recommissioned at the Puget Sound Navy Yard, Comdr. Sprague in command, and reported to Patrol Wing 5, Aircraft and her classification had been changed to AV–6, seaplane tender, on 11 October 1939. On 18 January 1940 she departed Puget Sound and, after taking on fuel and cargo at San Pedro and she steamed for the east coast on 5 February and reached Norfolk on 25 March. Next Patoka was assigned to the Naval Transportation Service in June and was reclassified AO–9 on 19 June 1940, on 13 August she departed Norfolk and sailed to Houston. Between August and December 1940, she operated out of Houston and Baytown, Texas, delivering oil to Boston, Melville, Norfolk, Charleston. From March 1941 to September Patoka delivered fuel oil and general cargo to units of the Fleet in the Atlantic, Gulf. On 28 September she departed Norfolk and proceeded, via Aruba, to Recife, Patoka made one more round trip to Recife before the United States entered World War II. On 7 December 1941, Patoka was moored at Recife, acting as tanker, cargo, store ship, here she supplied the units of Task Force 3 with fuel, diesel, lubricating oil, gasoline stores, provisions, and repairs. Shortly after the turn of the new year 1942, she got under way for Bahia, Brazil, there, she received word that ships bearing rubber and other vital war goods had left French Indochina bound for the Axis controlled ports in Europe. Patoka requested and received permission to patrol the shipping lanes off Bahia, when she had completed her patrol duties she put into port and returned to Recife on 22 January. Six days later she was bound for San Juan, Puerto Rico, taking on fuel and stores she returned to Recife

Mooring mast
–
A mooring mast, or mooring tower, is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure. After their development mooring masts became the standard approach to mooring airships as considerable manhandling was avoided, Airship mooring masts can be broadly divided into fixed high masts and fixed or mobile low masts. In the 1920s and 1930s masts were built in many countries, at least two were mounted on ships. The first airship known to have been moored to a mast was HMA No.1, named the ‘Mayfly’, the 38 ft mast was mounted on a pontoon, and a windbreak of cross-yards with strips of canvas were attached to it. However, the windbreak caused the ship to yaw badly, and she became more stable when it was removed, further experiments in mooring blimps to cable-stayed lattice masts were carried out during 1918. Mooring masts were developed to act as an open harbour to which airships could be moored or unmoored in any weather. Above the passenger platform was the 30 feet of the housing for the mooring gear. A lower platform 142 feet above the ground accommodated searchlights and signalling gear in a gallery 4 feet wide. The top platform, at the height of 170 feet, from which passengers embarked and disembarked to and from the airships, was 40 feet in diameter and encircled by a heavy parapet. The top rail of the parapet formed a track on which a gangway, let down from the airship, an electric passenger lift ran up the centre of the tower, encircled by a stairway to provide foot access. The upper portion of the tower, from the passenger platform upwards, was a steel turret surmounted by a truncated cone with its top 23 feet above the passenger platform. A three-part telescopic arm, mounted on gimbals, projected through an opening at the top, the top of the arm consisted of a bell-shaped cup mounted to rotate on ball bearings. The telescopic arm was then centred, locked in the vertical position, in the machinery house at the base of the tower three steam-driven winches operated the hauling gear through drums 5 feet in diameter to give cable hauling speeds of 50 feet a minute. The cable was then wound in with the airship riding about 600 feet above the mast and down wind. All three cables were wound in together, the main pull being taken on the mooring cable while the yaw guys steadied the ship. When all the cable had been wound, an articulated mooring cone on the nose of the airship locked home into the cup on the mast, the mast fitting was made free to rotate as the airship swung with the wind with freedom also for pitch and roll. A gangway, like a drawbridge, which could be drawn up flush with the nose of the airship, was let down with its free end resting on the parapet of the platform running round the mast

No. 60 Squadron RAF
–
No.60 Squadron of the Royal Air Force was formed in 1916 at Gosport. It is currently part of the Defence Helicopter Flying School based at RAF Shawbury in Shropshire, the squadron crest is a markhors head and was approved by King George VI in December 1937. Chosen to commemorate many years of service in North-West India, the markhor being a mountain goat frequenting the Khyber Pass, the horns of a markhor were presented to the squadron in 1964. The squadron motto is Per ardua ad aethera tendo - I strive through difficulties to the sky, formed at Gosport on 30 April 1916, barely a month had passed before the unit and its Morane-Saulnier Ns were despatched to France. After suffering heavy losses during the Battle of the Somme, the squadron re-equipped with Nieuport Scouts, on 2 June 1917, Captain W. A. A month later, S. E.5 fighters arrived, the squadron claimed 320 aerial victories. Chidlaw-Roberts John Doyle Art Duncan Gordon Duncan William M. Fry John Griffith Harold A. Hamersley H. George Hegarty Spencer B, the squadron moved to Burma in February 1941. After the outbreak of war against Japan the squadron fought in Malaya, two aircraft, L4912 and L4915, remained in Burma. Both were Blenheim Mk 1s and they were destroyed on 20 and 21 January 1942 respectively, L4912 had been damaged beyond repair during a mission in Burma and L4915 was destroyed by enemy bombing. When the war against Japan broke out on 8 December 1941 No.60 Squadron was ordered to attack Japanese shipping near Kota Baru, l4913 was shot down by Japanese anti-aircraft fire over the Gulf of Siam while attacking the Awagisan Maru. The pilot, Flight Lieutenant William Bowden, survived the crash and he was the first allied airman captured by the Japanese. He was imprisoned at the Zentsuji POW Camp where he remained until late June 1945 and he was then transferred to Tokyo No. 12D Camp at Mitsushima where he was freed in September 1945. On 24 December 1941 the remnant of squadrons ground crew and a few of its air crew, having lost all their aircraft in action, sailed from Singapore on the SS Darvel to Burma. They arrived in Rangoon on 1 January 1942 and were joined on 7 January 1942 by No.113 Squadron, No.60 Squadrons spare aircrew were assigned to No.113 Squadron as needed. Because the three squadrons lacked both aircraft and supplies they were able to put more than seven aircraft up at one time. No.60 Squadrons Blenheim aircrews manned No.113 Squadrons planes for the first bombing raid on Bangkok, the squadron had suffered heavily at the hands of the advancing Japanese forces and was declared non-operational and moved to Asansol, India along with No.45 and 113 Squadrons. Once in India the squadron was re-equipped with Blenheim Mk IVs, while returning to India from Burma after a bombing mission to Sitwe, Burma on 22 May a Blenheim the squadron was attacked by Nakajima Ki-43 fighters from 64 Sentai

Khyber Pakhtunkhwa
–
Khyber Pakhtunkhwa is one of the four provinces of Pakistan, located in the northwestern region of the country. It was formerly known as North-West Frontier Province and commonly called Sarhad and its provincial capital and largest city is Peshawar, followed by Mardan. It shares borders with the Federally Administered Tribal Areas to the west, Gilgit–Baltistan to the northeast, Azad Kashmir, Islamabad, Khyber Pakhtunkhwa does not share a border with Balochistan, which lies to its southwest. Khyber Pakhtunkhwa also shares a border with Afghanistan, connected through the Khyber Pass. It is also the site of the ancient kingdom Gandhara, the ruins of its capital, Pushkalavati, and the most prominent center of learning in the Peshawar Valley, Takht-i-Bahi. It has been under the suzerainty of the Persians, Greeks, Mauryans, Kushans, Shahis, Ghaznavids, Mughals, Afghanistan, Sikhs, Khyber Pakhtunkhwa is the third largest province of Pakistan by the size of both population and economy though it is geographically the smallest of four. It comprises 10. 5% of Pakistans economy, and is home to 11. 9% of Pakistans total population, with the majority of the inhabitants being Pashtuns, Hazarewal, Chitrali. Khyber Pakhtunkhwa means Khyber side of the land of Pakhtuns while only the word Pakhtunkhwa means Land of Pakhtuns and according to scholars it means Pakhtun culture. When the British established it as a province, they called it North West Frontier Province due to its location being in north west of their Indian Empire. After independence of Pakistan, Pakistan continued with this name but a Pakhtun nationalist party and their logic behind that demand was that Punjabi people, Sindhi people and Balochi people have their provinces named after their ethnicities but that is not the case for Pashtun people. Major political parties especially Pakistan Muslim League were against that name since it was too similar to Bacha Khans demand of separate nation Pashtunistan. The ancient Aryan Migration is believed to have taken place around 2000 BCE, darius Hystaspes sent Scylax, a Greek seaman from Karyanda, to explore the course of the Indus river. Darius Hystaspes subsequently subdued the races dwelling west of the Indus, Gandhara was incorporated into the Persian Empire as one of its far easternmost satrapy system of government. The satrapy of Gandhara is recorded to have sent troops for Xerxes invasion of Greece in 480 BCE, in the spring of 327 BCE Alexander the Great crossed the Indian Caucasus and advanced to Nicaea, where Omphis, king of Taxila and other chiefs joined him. Alexander then dispatched part of his force through the valley of the Kabul River, while he advanced into modern Khyber Pakhtunkhwas Bajaur. Alexander then made Embolima his base, after Alexanders death in 323 BCE Porus obtained possession of the region, but was murdered by Eudemus in 317 BCE. Eudemus then left the region, and with his departure Macedonian power collapsed, sandrocottus, the founder of the Mauryan dynasty, then declared himself master of the province. His grandson, Ashoka, made Buddhism the dominant religion in ancient Gandhara, after Ashokas death the Mauryan empire collapse, just as in the west the Seleucid power was rising

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Henry Berliner
–
Henry Adler Berliner was a United States aircraft and helicopter pioneer. Sixth son of inventor Emile Berliner, he was born in Washington, after a short time as aerial photographer with the Army Air Service, in 1919 Henry moved back to Washington to help his father with the helicopter research that had been underway for many years. Using a Le Rhône engine of 80 hp mounted on a test stand, Henry was able to hover and move forward, a third horizontal rotor at the rear provided pitch control. This was demonstrated at College Park, Maryland to the U. S. Navy’s Bureau of Aeronautics on June 16,1922, in 1923, Henry added a triple set of wings to his prototype, as a backup in case of engine failure. This machine could both hover, and reach speeds of 40 mph, but did not have the power to gain much altitude, its best performance, on February 23,1924. A1925 biplane-like design was lighter and more efficient, but performed better and was the Berliners last experiment. In the following year, Henry founded the Berliner Aircraft Company, the company merged to form Berliner-Joyce Aircraft in 1929 and was acquired by North American Aviation a few months later, in 1930 Berliner founded Engineering and Research Corporation. ERCO built the ERCO Ercoupe The triplane helicopter was donated to the Smithsonian Institution, a part of the collection at the National Air and Space Museum, it presently is on loan to the College Park Aviation Museum
