United States Army
The United States Army is the land warfare service branch of the United States Armed Forces. It is one of the seven uniformed services of the United States, is designated as the Army of the United States in the United States Constitution; as the oldest and most senior branch of the U. S. military in order of precedence, the modern U. S. Army has its roots in the Continental Army, formed to fight the American Revolutionary War —before the United States of America was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army; the United States Army considers itself descended from the Continental Army, dates its institutional inception from the origin of that armed force in 1775. As a uniformed military service, the U. S. Army is part of the Department of the Army, one of the three military departments of the Department of Defense; the U. S. Army is headed by a civilian senior appointed civil servant, the Secretary of the Army and by a chief military officer, the Chief of Staff of the Army, a member of the Joint Chiefs of Staff.
It is the largest military branch, in the fiscal year 2017, the projected end strength for the Regular Army was 476,000 soldiers. S. Army was 1,018,000 soldiers; as a branch of the armed forces, the mission of the U. S. Army is "to fight and win our Nation's wars, by providing prompt, land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders"; the branch participates in conflicts worldwide and is the major ground-based offensive and defensive force of the United States. The United States Army serves as the land-based branch of the U. S. Armed Forces. Section 3062 of Title 10, U. S. Code defines the purpose of the army as: Preserving the peace and security and providing for the defense of the United States, the Commonwealths and possessions and any areas occupied by the United States Supporting the national policies Implementing the national objectives Overcoming any nations responsible for aggressive acts that imperil the peace and security of the United StatesIn 2018, the Army Strategy 2018 articulated an eight-point addendum to the Army Vision for 2028.
While the Army Mission remains constant, the Army Strategy builds upon the Army's Brigade Modernization by adding focus to Corps and Division-level echelons. Modernization, reform for high-intensity conflict, Joint multi-domain operations are added to the strategy, to be completed by 2028; the Continental Army was created on 14 June 1775 by the Second Continental Congress as a unified army for the colonies to fight Great Britain, with George Washington appointed as its commander. The army was led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them; as the Revolutionary War progressed, French aid and military thinking helped shape the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben, who taught Prussian Army tactics and organizational skills; the army fought numerous pitched battles and in the South in 1780–1781, at times using the Fabian strategy and hit-and-run tactics, under the leadership of Major General Nathanael Greene, hit where the British were weakest to wear down their forces.
Washington led victories against the British at Trenton and Princeton, but lost a series of battles in the New York and New Jersey campaign in 1776 and the Philadelphia campaign in 1777. With a decisive victory at Yorktown and the help of the French, the Continental Army prevailed against the British. After the war, the Continental Army was given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army; the Regular Army was at first small and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army was reorganized as the Legion of the United States, established in 1791 and renamed the United States Army in 1796; the War of 1812, the second and last war between the United States and Great Britain, had mixed results.
The U. S. Army did not conquer Canada but it did destroy Native American resistance to expansion in the Old Northwest and it validated its independence by stopping two major British invasions in 1814 and 1815. After taking control of Lake Erie in 1813, the U. S. Army seized parts of western Upper Canada, burned York and defeated Tecumseh, which caused his Western Confederacy to collapse. Following U. S. victories in the Canadian province of Upper Canada, British troops who had dubbed the U. S. Army "Regulars, by God!", were able to capture and burn Washington, defended by militia, in 1814. The regular army, however proved they were professional and capable of defeating the British army during the invasions of Plattsburgh and Baltimore, prompting British agreement on the rejected terms of a status quo ante bellum. Two weeks after a treaty was signed, Andrew Jackson defeated the British in the Battle of New Orleans and Siege of Fort St. Philip, became a national hero. U. S. troops and sailors captured HMS Cyane and Penguin in the final engagements of the war.
Per the treaty, both sides (the United S
5"/38 caliber gun
The Mark 12 5"/38 caliber gun was a United States naval gun. The gun was installed into Single Purpose and Dual Purpose mounts used by the US Navy. On these 5" mounts, Single Purpose means that the mount is limited to 35° elevation with no provision for AA shell fuze setters, is designed to fire at surface targets only. Dual Purpose means that it is designed to be effective against both surface and aircraft targets because it can elevate to 85° and has on mount AA shell fuze setters; the 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile 5 inches in diameter, the barrel was 38 calibers long, making the 5"/38 dual purpose midway in barrel length between the 5"/51 surface-to-surface and the 5"/25 anti-aircraft guns; the increased barrel length provided improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun.
However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming; the 5"/38 entered service on USS Farragut, commissioned in 1934. The base ring mount, which improved the effective rate of fire, entered service on USS Gridley, commissioned in 1937. Among naval historians, the 5"/38 gun is considered the best intermediate-caliber, dual purpose naval gun of World War II as it was under the control of the advanced Mark 37 Gun Fire Control System which provided accurate and timely firing against surface and air targets; this advanced system required nearly 1000 rounds of ammunition expenditure per aircraft kill. However, the planes were killed by shell fragments and not direct hits; this would result in large walls of shell fragments being put up to take out one or several planes or in anticipation of an unseen plane, this being justifiable as one plane was capable of significant destruction. The comparatively high rate of fire for a gun of its caliber earned it an enviable reputation as an anti-aircraft weapon, in which role it was employed by United States Navy vessels.
Base ring mounts. On pedestal and other mounts lacking integral hoists, 12 to 15 rounds per minute was the rate of fire. Useful life expectancy was 4600 effective full charges per barrel; the 5"/38 cal gun was mounted on a large number of US Navy ships in the World War II era. It was backfitted to many of the World War I-era battleships during their wartime refits replacing 5"/25 guns that were fitted in the 1930s, it has left active US Navy service, but it is still on mothballed ships of the United States Navy reserve fleets. It is used by a number of nations who bought or were given US Navy surplus ships. Millions of rounds of ammunition were produced for these guns, with over 720,000 rounds still remaining in Navy storage depots in the mid-1980s because of the large number of Reserve Fleet ships with 5"/38 cal guns on board; each mount carries one or two Mk 12 5"/38cal Gun Assemblies. The gun assembly shown is used in single mounts, it is the right gun in twin mounts, it is loaded from the left side.
The left gun in twin mounts is the mirror image of the right gun, it is loaded from the right side. The Mk12 gun assembly weighs 3,990 lb; the Mark 12 Gun Assembly was introduced in 1934, where it was first used in single pedestal mounts on the Farragut-class destroyers, but by the time of World War II they had been installed in single and twin mounts on nearly every major warship and auxiliary in the US fleet. The major Mk12 Gun Assembly characteristics are::158 Semi-automatic During recoil, some of the recoil energy is stored in the counter-recoil system; that stored. The firing pin is cocked, the breech is opened, the spent propellant case is ejected, the bore is cleared of debris with an air blast. Hand loaded a powder-man are stationed at each gun assembly, their job is to move the round, consisting of a projectile and a propellant case, from the hoists to the rammer tray projecting from the gun's breech, start the ram cycle. Power rammed This gun used a 7.5 hp electric-hydraulic power rammer, designed to ram a 93 lb, 47.5 in long round into the chamber at any gun elevation in less than one second.:172 The rammer's control box, hydraulic fluid tank and AC motor are bolted to the top of the slide.
The hydraulically driven rammer spade, called the power spade in that picture, is at the back of the rammer tray. If the multiple names of the "spade" are confusing, look at this footnote. Vertical sliding-wedge breech block, it contains the firing pin assembly. Hydraulic recoil Two hydraulic pistons in the housing absorb the major shock of recoil as the housing moves back inside the slide, they buffer the end of counter-recoil for a soft return to battery. Pneumatic counter-recoil At the end of recoil, the counter-recoil system moves the housing forward again until it is back "in battery," and holds it there at any gun elevation. A chamber in the housing is filled with compressed air. At the rear of this chamber is a 3.5 in cylindrical hole with a c
Destroyer escort was the United States Navy mid-20th-century classification for a 20-knot warship designed with endurance to escort mid-ocean convoys of merchant marine ships. Kaibōkan were designed for a similar role in the Imperial Japanese Navy; the Royal Navy and Commonwealth forces identified such warships as frigates, that classification was accepted when the United States redesignated destroyer escorts as frigates in 1975. Destroyer escorts and kaibōkan were mass-produced for World War II as a less expensive antisubmarine warfare alternative to fleet destroyers. Other similar warships include the 10 Kriegsmarine escort ships of the F-class and the two Amiral Murgescu-class vessels of the Romanian Navy. Postwar destroyer escorts and frigates were larger than those produced during wartime, with increased antiaircraft capability, but remained smaller and slower than postwar destroyers; as Cold War destroyer escorts became as large as wartime destroyers, the United States Navy converted some of their World War II destroyers to escort destroyers.
Full-sized destroyers must be able to steam as fast or faster than the fast capital ships such as fleet carriers and cruisers. This requires a speed of 25–35 knots, they must carry torpedoes and a smaller caliber of cannon to use against enemy ships, as well as antisubmarine detection equipment and weapons. A destroyer escort needed only to be able to maneuver relative to a slow convoy, be able to defend against aircraft, detect and attack submarines; these lower requirements reduce the size and crew required for the destroyer escort. Destroyer escorts were optimized for antisubmarine warfare, having a tighter turning radius and more specialized armament than fleet destroyers, their much slower speed was not a liability in this context, since sonar was useless at speeds over 20 knots. Destroyer escorts were considerably more sea-kindly than corvettes; as an alternative to steam-turbine propulsion found in full-sized destroyers and larger warships, many US destroyer escorts of the World War II period had diesel-electric or turboelectric drive, in which the engine rooms functioned as power stations supplying current to electric motors sited close to the propellers.
Electric drive was selected because it does not need gearboxes to adjust engine speed to the much lower optimum speed for the propellers. The current from the engine room can be used well for other purposes, after World War II, many destroyer escorts were recycled as floating power stations for coastal cities in Latin America under programs funded by the World Bank. Destroyer escorts were useful for coastal antisubmarine and radar picket ship duty. During World War II, seven destroyer escorts were converted to radar picket destroyer escorts, supplementing radar picket destroyers. Although these were relegated to secondary roles after the war, in the mid-1950s, 12 more DEs were converted to DERs, serving as such until 1960-1965, their mission was to extend the distant early warning line on both coasts, in conjunction with 16 Guardian-class radar picket ships, which were converted Liberty ships. In World War II, some 95 destroyer escorts were converted by the US to high-speed transports; this involved adding an extra deck which allowed space for 150 men.
Two large davits were installed, one on either side of the ship, from which landing craft could be launched. The Lend-Lease Act was passed into law in the United States in March 1941, enabling the United Kingdom to procure merchant ships, warships and other materiel from the US, to help with the war effort; this enabled the UK to commission the US to design and supply an escort vessel, suitable for antisubmarine warfare in deep open-ocean situations, which they did in June 1941. Captain E. L. Cochrane of the American Bureau of Shipping came up with a design, known as the British destroyer escort; the BDE designation was retained by the first six destroyer escorts transferred to the United Kingdom. When the United States entered the war, found they required an antisubmarine warfare ship and that the destroyer escort fitted their needs a system of rationing was put in place whereby out of every five destroyer escorts completed, four would be allocated to the U. S. Navy and one to the Royal Navy.
After World War II, United States Navy destroyer escorts were referred to as ocean escorts, but retained the hull classification symbol DE. However, other navies, most notably those of NATO countries and the USSR, followed different naming conventions for this type of ship, which resulted in some confusion. To remedy this problem, the 1975 ship reclassification declared; this brought the USN's nomenclature more in line with NATO, made comparing ship types with the Soviet Union easier. As of 2006, no plans existed for future frigates for the US Navy. USS Zumwalt and the littoral combat ship were the main ship types planned in this area. However, by 2017 the Navy had reversed course, put out a Request For Proposals for a new frigate class, temporarily designated FFG. One major problem with ship classification is whether to base it on a ship's role, or on its size (s
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. Naval aviation is projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand demanding carrier operations, they must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck. These aircraft are designed for many purposes, including air-to-air combat, surface attack, submarine attack and rescue, matériel transport, weather observation and wide area command and control duties. Early experiments on the use of kites for naval reconnaissance took place in 1903 at Woolwich Common for the Admiralty. Samuel Franklin Cody demonstrated the capabilities of his 8 foot long black kite and it was proposed for use as either a mechanism to hold up wires for wireless communications or as a manned reconnaissance device that would give the viewer the advantage of considerable height.
In 1908 Prime Minister H. H. Asquith approved the formation of an "Aerial Sub-Committee of the Committee of Imperial Defence" to investigate the potential for naval aviation. In 1909 this body accepted the proposal of Captain Reginald Bacon made to the First Sea Lord Sir John Fisher that rigid airships should be constructed for the Royal Navy to be used for reconnaissance; this resulted in the construction of Mayfly in 1909, the first air component of the navy to become operational, the genesis of modern naval aviation. The first pilots for the Royal Navy were transferred from the Royal Aero Club in June 1910 along with two aircraft with which to train new pilots, an airfield at Eastchurch became the Naval Flying School, the first such facility in the world. Two hundred applications were received, four were accepted: Lieutenant C R Samson, Lieutenant A M Longmore, Lieutenant A Gregory and Captain E L Gerrard, RMLI; the French established a naval aviation capability in 1910 with the establishment of the Service Aeronautique and the first flight training schools.
U. S. naval aviation began with pioneer aviator Glenn Curtiss who contracted with the United States Navy to demonstrate that airplanes could take off from and land aboard ships at sea. One of his pilots, Eugene Ely, took off from the cruiser USS Birmingham anchored off the Virginia coast in November 1910. Two months Ely landed aboard another cruiser, USS Pennsylvania, in San Francisco Bay, proving the concept of shipboard operations. However, the platforms erected on; the U. S. Navy and Glenn Curtiss experienced two firsts during January 1911. On 27 January, Curtiss flew the first seaplane from the water at San Diego Bay and the next day U. S. Navy Lt. Theodore G. Ellyson, a student at the nearby Curtiss School, took off in a Curtiss "grass cutter" plane to become the first naval aviator. $25,000 was appropriated for the Bureau of Navigation to purchase three airplanes and in the spring of 1911 four additional officers were trained as pilots by the Wright brothers and Curtiss. A camp with a primitive landing field was established on the Severn River at Greenbury Point, near Annapolis, Maryland.
The group expanded with the addition of six aviators in 1912 and five in 1913, from both the Navy and Marine Corps, conducted maneuvers with the Fleet from the battleship USS Mississippi, designated as the Navy's aviation ship. Meanwhile, Captain Henry C. Mustin tested the concept of the catapult launch in August 1912, in 1915 made the first catapult launching from a ship underway; the first permanent naval air station was established at Pensacola, Florida, in January 1914 with Mustin as its commanding officer. On April 24 of that year, for a period of 45 days afterward, five floatplanes and flying boats flown by ten aviators operated from Mississippi and the cruiser Birmingham off Veracruz and Tampico, Mexico conducting reconnaissance for troops ashore in the wake of the Tampico Affair. In January 1912, the British battleship HMS Africa took part in aircraft experiments at Sheerness, she was fitted for flying off aircraft with a 100-foot downward-sloping runway, installed on her foredeck, running over her forward 12-inch gun turret from her forebridge to her bow and equipped with rails to guide the aircraft.
The Gnome-engined Short Improved S.27 "S.38", pusher seaplane piloted by Lieutenant Charles Samson become the first British aircraft to take-off from a ship while at anchor in the River Medway, on 10 January 1912. Africa transferred her flight equipment to her sister ship Hibernia. In May 1912, with Commander Samson again flying the "S.38", the first instance of an aircraft to take off from a ship, under way occurred. Hibernia steamed at 10.5 knots at the Royal Fleet Review in England. Hibernia transferred her aviation equipment to battleship London. Based on these experiments, the Royal Navy concluded that aircraft were useful aboard ship for spotting and other purposes, but that interference with the firing of guns caused by the runway built over the foredeck and the danger and impracticality of recovering seaplanes that alighted in the water in anything but calm weather more than offset the desirability of having airplanes aboard. In 1912, the nascent naval air detachment in the United Kingdom was amalgamated to form the Royal Flying Corps and in 1913 a seaplane base on the Isle of Grain, an airship base at Kingsnorth and eight new airfields were approved for construction.
The first aircraft participation in naval manoeu
Curaçao is a Lesser Antilles island in the southern Caribbean Sea and the Dutch Caribbean region, about 65 km north of the Venezuelan coast. It is a constituent country of the Kingdom of the Netherlands; the country was part of the Curaçao and Dependencies colony and is now formally called the Country of Curaçao. Curaçao has a population over 160,000 in an area of 444 km2 and its capital is Willemstad. Before the dissolution of the Netherlands Antilles on 10 October 2010, Curaçao was administered as the "Island Territory of Curaçao", one of five island territories of the former Netherlands Antilles. In the 16th and 17th centuries, sailors on long voyages would get scurvy from lack of vitamin C. According to some accounts, Portuguese sailors who were ill were left at the island now known as Curaçao; when their ship returned, they had recovered cured from scurvy after eating fruit with vitamin C. From on the Portuguese referred to this as Ilha da Curação. Another explanation is that it is derived from the Portuguese word for heart, referring to the island as a centre in trade.
An unstressed o in Continental Portuguese is pronounced, so the Portuguese word for heart, coração, is pronounced. Spanish traders took the name over as Curaçao, followed by the Dutch. Another explanation is that Curaçao was the name by which the indigenous peoples of the island identified themselves, their autonym. Early Spanish accounts support this theory, as they refer to the indigenous peoples as Indios Curaçaos, or "healing Indians". From 1525, the island was featured on Spanish maps as Curaçote and Curasaore. By the 17th century, it appeared on most maps in Portuguese as Curazao. On a map created by Hieronymus Cock in 1562 in Antwerp, the island was referred to as Qúracao; the original inhabitants of Curaçao were Arawak people. Their ancestors had migrated to the island from the mainland of South America hundreds of years before Europeans arrived, they were believed to have migrated from the Amazon Basin. The first Europeans recorded as seeing the island were members of a Spanish expedition under the leadership of Alonso de Ojeda in 1499.
The Spaniards enslaved most of the Arawak as their labour force. They sometimes forcibly relocated the survivors to other colonies. In 1634, after the Netherlands achieved independence from Spain caused by Eighty Years' War, Dutch colonists started to occupy the island. European powers were trying to establish bases in the Caribbean; the Dutch West India Company founded the capital of Willemstad on the banks of an inlet called the Schottegat. Curaçao had been ignored by colonists; the natural harbour of Willemstad proved to be an ideal spot for trade. Commerce and shipping -- and piracy -- became. In addition, in 1662, the Dutch West India Company made Curaçao a centre for the Atlantic slave trade bringing slaves here for sale elsewhere in the Caribbean and on the mainland of South America. Sephardic Jews with ancestors from the Iberian Peninsula settled here with the Dutch and in then-Dutch Brazil. In the Franco-Dutch War, Count Jean II d'Estrées planned to attack Curaçao, his fleet – 12 men of war, three fireships, two transports, a hospital ship, 12 privateers – met with disaster, losing seven men-of-war and two other ships when they struck reefs off the Las Aves archipelago.
They had made a serious navigational error, hitting the reefs on 11 May 1678, a week after setting sail from Saint Kitts. Curaçao marked the events by a day of thanksgiving, celebrated for decades into the 18th century, to commemorate the island's escape from being invaded by the French. Although a few plantations were established on the island by the Dutch, the first profitable industry established on Curaçao was salt mining; the mineral was a lucrative export at the time and was a major factor for the island being part of international commerce. Many Dutch colonists grew affluent from the slave trade, the city built impressive colonial buildings. Curaçao architecture blends Dutch and Spanish colonial styles; the wide range of historic buildings in and around Willemstad has resulted in the capital being designated as a UNESCO World Heritage Site. Landhouses and West African style kas di pal'i maishi are scattered all over the island; some can be visited. In 1795, a major slave revolt took place under the leaders Tula Rigaud, Louis Mercier, Bastian Karpata, Pedro Wakao.
Up to 4000 slaves on the northwest section of the island revolted. More than 1,000 slaves took part in extended gunfights. After a month, the slave owners suppressed the revolt. Curaçao's proximity to South America resulted in interaction with cultures of the coastal areas more than a century after independence of Netherlands from Spain. Architectural similarities can be seen between the 19th-century parts of Willemstad and the nearby Venezuelan city of Coro in Falcón State; the latter has been designated a UNESCO World Heritage Site. Netherlands established economic ties with Viceroyalty of New Granada, which includes present-day countries of Colombia and Venezuela. In the 19th century, Curaçaoans such as Manuel Piar and Luis Brión were prominently engaged in the wars of independen
General Electric Company is an American multinational conglomerate incorporated in New York and headquartered in Boston. As of 2018, the company operates through the following segments: aviation, power, renewable energy, digital industry, additive manufacturing, venture capital and finance and oil and gas. In 2018, GE ranked among the Fortune 500 as the 18th-largest firm in the U. S. by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th-most profitable company but has since severely underperformed the market as its profitability collapsed. Two employees of GE—Irving Langmuir and Ivar Giaever —have been awarded the Nobel Prize. During 1889, Thomas Edison had business interests in many electricity-related companies including Edison Lamp Company, a lamp manufacturer in East Newark, New Jersey. P. Morgan and the Vanderbilt family for Edison's lighting experiments. In 1889, Morgan & Co. a company founded by J. P. Morgan and Anthony J. Drexel, financed Edison's research and helped merge those companies under one corporation to form Edison General Electric Company, incorporated in New York on April 24, 1889.
The new company acquired Sprague Electric Railway & Motor Company in the same year. In 1880, Gerald Waldo Hart formed the American Electric Company of New Britain, which merged a few years with Thomson-Houston Electric Company, led by Charles Coffin. In 1887, Hart left to become superintendent of the Edison Electric Company of Missouri. General Electric was formed through the 1892 merger of Edison General Electric Company of Schenectady, New York, Thomson-Houston Electric Company of Lynn, with the support of Drexel, Morgan & Co. Both plants continue to operate under the GE banner to this day; the company was incorporated in New York, with the Schenectady plant used as headquarters for many years thereafter. Around the same time, General Electric's Canadian counterpart, Canadian General Electric, was formed. In 1896, General Electric was one of the original 12 companies listed on the newly formed Dow Jones Industrial Average, where it remained a part of the index for 122 years, though not continuously.
In 1911, General Electric absorbed the National Electric Lamp Association into its lighting business. GE established its lighting division headquarters at Nela Park in Ohio; the lighting division has since remained in the same location. Owen D. Young, through GE, founded the Radio Corporation of America in 1919, after purchasing the Marconi Wireless Telegraph Company of America, he aimed to expand international radio communications. GE used RCA as its retail arm for radio sales. In 1926, RCA co-founded the National Broadcasting Company, which built two radio broadcasting networks. In 1930, General Electric was charged with antitrust violations and decided to divest itself of RCA. In 1927, Ernst Alexanderson of GE made the first demonstration of his television broadcasts at his General Electric Realty Plot home at 1132 Adams Rd, New York. On January 13, 1928, he made what was said to be the first broadcast to the public in the United States on GE's W2XAD: the pictures were picked up on 1.5 square inch screens in the homes of four GE executives.
The sound was broadcast on GE's WGY. Experimental television station W2XAD evolved into station WRGB which, along with WGY and WGFM, was owned and operated by General Electric until 1983. Led by Sanford Alexander Moss, GE moved into the new field of aircraft turbo superchargers. GE introduced the first set of superchargers during World War I, continued to develop them during the interwar period. Superchargers became indispensable in the years prior to World War II. GE supplied 300,000 turbo superchargers for use in bomber engines; this work led the U. S. Army Air Corps to select GE to develop the nation's first jet engine during the war; this experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine, demonstrated in the United States in 1941. GE was ranked ninth among United States corporations in the value of wartime production contracts. Although, their early work with Whittle's designs was handed to Allison Engine Company. GE Aviation emerged as one of the world's largest engine manufacturers, bypassing the British company, Rolls-Royce plc.
Some consumers boycotted GE light bulbs and other products during the 1980s and 1990s. The purpose of the boycott was to protest against GE's role in nuclear weapons production. In 2002, GE acquired the wind power assets of Enron during its bankruptcy proceedings. Enron Wind was the only surviving U. S. manufacturer of large wind turbines at the time, GE increased engineering and supplies for the Wind Division and doubled the annual sales to $1.2 billion in 2003. It acquired ScanWind in 2009. In 2015, GE Power garnered press attention when a model 9FB gas turbine in Texas was shut down for two months due to the break of a turbine blade; this model uses similar blade technology to GE's newest and most efficient model, the 9HA. After the break, GE developed heat treatment methods. Gas turbines represent a significant portion of GE Power's revenue, represent a significant portion of the power generation fleet of several utility companies in the United States. Chubu Electric of Japan and Électricité de France had units that were impacted.
England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity.
