A journalist is a person who collects, writes, or distributes news or other current information to the public. A journalist's work is called journalism. A journalist can specialize in certain issues. However, most journalists tend to specialize, by cooperating with other journalists, produce journals that span many topics. For example, a sports journalist covers news within the world of sports, but this journalist may be a part of a newspaper that covers many different topics. A reporter is a type of journalist who researches and reports on information in order to present in sources, conduct interviews, engage in research, make reports; the information-gathering part of a journalist's job is sometimes called reporting, in contrast to the production part of the job such as writing articles. Reporters may split their time between working in a newsroom and going out to witness events or interviewing people. Reporters may be assigned a specific area of coverage. Depending on the context, the term journalist may include various types of editors, editorial writers and visual journalists, such as photojournalists.
Journalism has developed a variety of standards. While objectivity and a lack of bias are of primary concern and importance, more liberal types of journalism, such as advocacy journalism and activism, intentionally adopt a non-objective viewpoint; this has become more prevalent with the advent of social media and blogs, as well as other platforms that are used to manipulate or sway social and political opinions and policies. These platforms project extreme bias, as "sources" are not always held accountable or considered necessary in order to produce a written, televised, or otherwise "published" end product. Matthew C. Nisbet, who has written on science communication, has defined a "knowledge journalist" as a public intellectual who, like Walter Lippmann, David Brooks, Fareed Zakaria, Naomi Klein, Michael Pollan, Thomas Friedman, Andrew Revkin, sees their role as researching complicated issues of fact or science which most laymen would not have the time or access to information to research themselves communicating an accurate and understandable version to the public as a teacher and policy advisor.
In his best-known books, Public Opinion and The Phantom Public, Lippmann argued that most individuals lacked the capacity and motivation to follow and analyze news of the many complex policy questions that troubled society. Nor did they directly experience most social problems, or have direct access to expert insights; these limitations were made worse by a news media that tended to over-simplify issues and to reinforce stereotypes, partisan viewpoints, prejudices. As a consequence, Lippmann believed that the public needed journalists like himself who could serve as expert analysts, guiding “citizens to a deeper understanding of what was important.” In 2018, the United States Department of Labor's Occupational Outlook Handbook reported that employment for the category, "reporters and broadcast news analysts," will decline 9 percent between 2016 and 2026. Journalists sometimes expose themselves to danger when reporting in areas of armed conflict or in states that do not respect the freedom of the press.
Organizations such as the Committee to Protect Journalists and Reporters Without Borders publish reports on press freedom and advocate for journalistic freedom. As of November 2011, the Committee to Protect Journalists reports that 887 journalists have been killed worldwide since 1992 by murder, crossfire or combat, or on dangerous assignment; the "ten deadliest countries" for journalists since 1992 have been Iraq, Russia, Mexico, Pakistan, Somalia and Sri Lanka. The Committee to Protect Journalists reports that as of December 1, 2010, 145 journalists were jailed worldwide for journalistic activities. Current numbers are higher; the ten countries with the largest number of currently-imprisoned journalists are Turkey, Iran, Burma, Vietnam, Cuba and Sudan. Apart from the physical harm, journalists are harmed psychologically; this applies to war reporters, but their editorial offices at home do not know how to deal appropriately with the reporters they expose to danger. Hence, a systematic and sustainable way of psychological support for traumatized journalists is needed.
However, only little and fragmented support programs exist so far. The Newseum in Washington, D. C. is home to the Journalists Memorial, which lists the names of over 2,100 journalists from around the world who were killed in the line of duty. The relationship between a professional journalist and a source can be rather complex, a source can sometimes impact the direction of the article written by the journalist; the article'A Compromised Fourth Estate' uses Herbert Gans' metaphor to capture their relationship. He uses a dance metaphor'The Tango' to illustrate the co-operative nature of their interactions "It takes two to tango". Herbert suggests that the source leads but journalists object to this notion for two reasons: It signals source supremacy in news making, it offends journalists' professional culture, which emphasizes editorial autonomy. This dance metaphor helps showcase consensus within the relationship but the article describe the common relation between the two "A relationship with sources, too cozy is compromising of journalists’ integrity and risks becoming collusive.
Journalists have favored a
University of Colorado Boulder
The University of Colorado Boulder is a public research university located in Boulder, United States. It is the flagship university of the University of Colorado system and was founded five months before Colorado was admitted to the Union in 1876. In 2015, the university comprised nine colleges and schools and offered over 150 academic programs and enrolled 17,000 students. Twelve Nobel Laureates, nine MacArthur Fellows, 20 astronauts have been affiliated with CU Boulder as students, researchers, or faculty members in its history; the university received nearly $454 million in sponsored research in 2010 to fund programs like the Laboratory for Atmospheric and Space Physics, JILA. The Colorado Buffaloes compete in 17 varsity sports and are members of the NCAA Division I Pac-12 Conference; the Buffaloes have won 28 national championships: 20 in skiing, seven total in men's and women's cross country, one in football. 900 students participate in 34 intercollegiate club sports annually as well. On March 14, 1876, the Colorado territorial legislature passed an amendment to the state constitution that provided money for the establishment of the University of Colorado in Boulder, the Colorado School of Mines in Golden, the Colorado Agricultural College in Fort Collins.
Two cities competed for the site of the University of Colorado: Cañon City. The consolation prize for the losing city was to be home of the new Colorado State Prison. Cañon City was at a disadvantage as it was the home of the Colorado Territorial Prison; the cornerstone of the building that became Old Main was laid on September 20, 1875. The doors of the university opened on September 5, 1877. At the time, there were few high schools in the state that could adequately prepare students for university work, so in addition to the University, a preparatory school was formed on campus. In the fall of 1877, the student body consisted of 15 students in the college proper and 50 students in the preparatory school. There were 38 men and 27 women, their ages ranged from 12–23 years. During World War II, Colorado was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program which offered students a path to a navy commission; the main CU Boulder campus is located south of the Pearl Street Mall and east of Chautauqua Auditorium.
It consists of residential buildings as well as research facilities. The East Campus is about a quarter mile from the main campus and is composed of athletic fields and research buildings. CU Boulder's distinctive architecture style, known as Tuscan Vernacular Revival, was designed by architect Charles Klauder; the oldest buildings, such as Old Main and Macky Auditorium, were in the Collegiate Gothic style of many East Coast schools, Klauder's initial plans for the university's new buildings were in the same style. A month or so after approval, Klauder updated his design by sketching in a new wrap of rough, textured sandstone walls with sloping, multi-leveled red-tiled roofs and Indiana limestone trim; this formed the basis of a unified style, used in the design of fifteen other buildings between 1921 and 1939 and still followed on the campus to this day. The sandstone used in the construction of nearly all the buildings on campus was selected from a variety of Front Range mountain quarries.
In 2011, Travel+Leisure named the Boulder campus one of the most beautiful college campuses in the United States. Freshmen and others attending the University of Colorado Boulder have an option of 24 on- and off-campus residence halls. Residence halls have 17 varieties of room types from singles to four-person rooms and others with apartment style amenities. There are several communities of residence halls located throughout the campus, as well as in a separate area called Williams Village, located 1.5 miles off of main campus. There is a free bus service that transports students to main campus from Williams Village and vice versa; the University offers Residential Academic Programs in many of its Residence Halls. RAPs provide students with in-dorm classes tailored to academic interests; the Engineering Center on the North-East side of campus houses the nation's largest geotechnical centrifuge as well as ion-implantation and microwave-propagation facilities, spectrometers and other microscopes, a structural analysis facility.
Until 1903, the library collection was housed with the rest of the school in Old Main. The growing size of the library required a move, as the weight of the books was causing physical damage to the floor; the cornerstone for the first separate library building was laid in January 1903, the building was opened in January 1904. When the new Norlin Library opened in 1940, the old library turned over to the Theatre department, was converted into classrooms and a theatre. Norlin Library was the last building to be designed by Klauder. There are two inscriptions on the western face of the building. Both were composed by President Norlin; the larger inscription reads "Who knows only his own generation remains always a child," based on a Cicero quotation, while the smaller inscription on the marble just over the door reads "Enter here the timeless fellowship of the human spirit." Macky Auditorium is a large building on the north edge of the University of Colorado campus, near 17th Street and University Avenue, which plays host to various talks and musical performances.
Andrew J. Macky was a prominent businessman involved with the town of Boulder in the late 19th century. Macky
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation, it involves formulating hypotheses, via induction, based on such observations. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Though diverse models for the scientific method are available, there is in general a continuous process that includes observations about the natural world. People are inquisitive, so they come up with questions about things they see or hear, they develop ideas or hypotheses about why things are the way they are; the best hypotheses lead to predictions. The most conclusive testing of hypotheses comes from reasoning based on controlled experimental data. Depending on how well additional tests match the predictions, the original hypothesis may require refinement, expansion or rejection.
If a particular hypothesis becomes well supported, a general theory may be developed. Although procedures vary from one field of inquiry to another, they are the same from one to another; the process of the scientific method involves making conjectures, deriving predictions from them as logical consequences, carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while seeking answers to the question; the hypothesis might be specific, or it might be broad. Scientists test hypotheses by conducting experiments or studies. A scientific hypothesis must be falsifiable, implying that it is possible to identify a possible outcome of an experiment or observation that conflicts with predictions deduced from the hypothesis; the purpose of an experiment is to determine whether observations agree with or conflict with the predictions derived from a hypothesis. Experiments can take place anywhere from a garage to CERN's Large Hadron Collider.
There are difficulties in a formulaic statement of method, however. Though the scientific method is presented as a fixed sequence of steps, it represents rather a set of general principles. Not all steps take place in every scientific inquiry, they are not always in the same order; some philosophers and scientists have argued. Robert Nola and Howard Sankey remark that "For some, the whole idea of a theory of scientific method is yester-year's debate, the continuation of which can be summed up as yet more of the proverbial deceased equine castigation. We beg to differ." Important debates in the history of science concern rationalism as advocated by René Descartes. The term "scientific method" emerged in the 19th century, when a significant institutional development of science was taking place and terminologies establishing clear boundaries between science and non-science, such as "scientist" and "pseudoscience", appeared. Throughout the 1830s and 1850s, by which time Baconianism was popular, naturalists like William Whewell, John Herschel, John Stuart Mill engaged in debates over "induction" and "facts" and were focused on how to generate knowledge.
In the late 19th and early 20th centuries, a debate over realism vs. antirealism was conducted as powerful scientific theories extended beyond the realm of the observable. The term "scientific method" came into popular use in the twentieth century, popping up in dictionaries and science textbooks, although there was little scientific consensus over its meaning. Although there was a growth through the middle of the twentieth century, by the end of that century numerous influential philosophers of science like Thomas Kuhn and Paul Feyerabend had questioned the universality of the "scientific method" and in doing so replaced the notion of science as a homogeneous and universal method with that of it being a heterogeneous and local practice. In particular, Paul Feyerabend argued against there being any universal rules of science. Historian of science Daniel Thurs maintains that the scientific method is a myth or, at best, an idealization; the scientific method is the process. As in other areas of inquiry, science can build on previous knowledge and develop a more sophisticated understanding of its topics of study over time.
This model can be seen to underlie the scientific revolution. The ubiquitous element in the model of the scientific method is empiricism, or more epistemologic sensualism; this is in opposition to stringent forms of rationalism: the scientific method embodies that reason alone cannot solve a particular scientific problem. A strong formulation of the scientific method is not always aligned with a form of empiricism in which the empirical data is put forward in the form of experience or other abstracted forms of knowledge; the scientific method is of necessity als
Retirement is the withdrawal from one's position or occupation or from one's active working life. A person may semi-retire by reducing work hours. An increasing number of individuals are choosing to put off this point of total retirement, by selecting to exist in the emerging state of pre-tirement. Many people choose to retire when they are eligible for private or public pension benefits, although some are forced to retire when bodily conditions no longer allow the person to work any longer or as a result of legislation concerning their position. In most countries, the idea of retirement is of recent origin, being introduced during the late 19th and early 20th centuries. Low life expectancy and the absence of pension arrangements meant that most workers continued to work until death. Germany was the first country to introduce retirement benefits in 1889. Nowadays, most developed countries have systems to provide pensions on retirement in old age, which may be sponsored by employers or the state.
In many poorer countries, support for the old is still provided through the family. Today, retirement with a pension is considered a right of the worker in many societies, hard ideological, social and political battles have been fought over whether this is a right. In many western countries this right is mentioned in national constitutions. Retirement, or the practice of leaving one's job or ceasing to work after reaching a certain age, has been around since around the 18th century. Prior to the 18th century, humans had an average life expectancy between 40 years. In consequence, only a small percentage of the population reached an age where physical impairments began to be obstacles to working. Countries began to adopt government policies on retirement during the late 19th century and the 20th century, beginning in Germany under Otto von Bismarck. A person may retire. However, a country's tax laws or state old-age pension rules mean that in a given country a certain age is thought of as the "standard" retirement age.
The "standard" retirement age varies from country to country but it is between 50 and 70. In some countries this age is different for males and females, although this has been challenged in some countries, in some countries the ages are being brought into line; the table below shows the variation in eligibility ages for public old-age benefits in the United States and many European countries, according to the OECD. Notes: Parentheses indicate eligibility age for women when different. Sources: Cols. 1–2: OECD Pensions at a Glance, Cols. 3–6: Tabulations from HRS, ELSA and SHARE. Square brackets indicate early retirement for some public employees. 1 In Denmark, early retirement is called efterløn and there are some requirements to be met. Early and normal retirement age depends on the birthday of the person filing for retirement.2 In France, the retirement age has been extended to 62 and 67 over the next eight years.3 In Latvia, the retirement age depends on the birthday of the person filing for retirement.4 In Spain, the retirement age will be extended to 63 and 67 this increase will be progressively done from 2013 to 2027 at a rate of 1 month during the first 6 years and 2 months during the other 9.
In the United States, while the normal retirement age for Social Security, or Old Age Survivors Insurance has been age 65 to receive unreduced benefits, it is increasing to age 67. For those turning 65 in 2008, full benefits will be payable beginning at age 66. Public servants are not covered by Social Security but have their own pension programs. Police officers in the United States are allowed to retire at half pay after only 20 years of service or three-quarter pay after 30 years, allowing people to retire in their early forties or fifties. Military members of the US Armed Forces may elect to retire after 20 years of active duty, their retirement pay is calculated on total number of years on active duty, their final pay grade and the retirement system in place when they entered service. Allowances such as housing and subsistence are not used to calculate a member's retired pay. Members awarded the Medal of Honor qualify for a separate stipend, regardless of the years of service. Military members in the reserve and US National Guard have their retirement based on a point system.
Recent advances in data collection have vastly improved our ability to understand important relationships between retirement and factors such as health, employment characteristics and family dynamics, among others. The most prominent study for examining retirement behavior in the United States is the ongoing Health and Retirement Study, first fielded in 1992; the HRS is a nationally representative longitudinal survey of adults in the U. S. ages 51+, conducted every two years, contains a wealth of information on such topics as labor force participation, financial variables, family characteristics and a host of other topics.2002 and 2004 saw the introductions of the English Longitudinal Study of Ageing and the Survey of Health and Retirement in Europe, which includes respondents from 14 continental European countri
Donald Edward Keyhoe was an American Marine Corps naval aviator, writer of many aviation articles and stories in a variety of leading publications, manager of the promotional tours of aviation pioneers of Charles Lindbergh. In the 1950s he became well known as a UFO researcher, arguing that the U. S. government should conduct appropriate research in UFO matters, should release all its UFO files. Jerome Clark writes that "Keyhoe was regarded as the leader in the field" of ufology in the 1950s and early to mid-1960s. Keyhoe was raised in Ottumwa, Iowa. Upon receiving his B. S. degree from the United States Naval Academy in 1919, he was commissioned as a Second Lieutenant in the United States Marine Corps. In 1922, his arm was injured during an airplane crash in Guam. During his long convalescence, Keyhoe began writing as a hobby, he returned to active duty, but the injury gave Keyhoe persistent trouble, and, as a result, he retired from the Marines in 1923. He worked for the National Geodetic Survey and U.
S. Department of Commerce. In 1927, Keyhoe managed a popular coast-to-coast tour by Charles Lindbergh; this led to Keyhoe's first book, 1928's Flying With Lindbergh. The book was a quick success, led to a freelance writing career, with many of Keyhoe's articles and fictional stories appearing in a variety of leading publications. Keyhoe returned to active duty during World War II in a Naval Aviation Training Division before retiring again at the rank of Major. By the time his UFO books appeared, Keyhoe was a well-established author, with numerous appearances in the pulp magazines of the 1920s and 1930s. Four of his short stories were printed in Weird Tales, one of the most prestigious of the pulps: "The Grim Passenger", "The Mystery Under the Sea", "Through the Vortex" and "The Master of Doom", he produced the lead novel for all three issues of a short-lived magazine called Dr. Yen Sin: "The Mystery of the Dragon's Shadow", "The Mystery of the Golden Skull" and "The Mystery of the Singing Mummies".
The Doctor was opposed by a hero. Keyhoe wrote a number of air adventure stories for Flying Aces, other magazines, created two larger-than-life superheroes in this genre; the first of these was Captain Philip Strange, referred to as "the Brain Devil" and "the Phantom Ace of G-2." Captain Strange was an American intelligence officer during World War I, gifted with ESP and other mental powers. His existence has been perpetuated beyond Keyhoe's stories as a minor member of the Wold Newton universe. Keyhoe's other "superpowered" flying ace was Richard Knight, a World War I veteran, blinded in combat but gained a supernatural ability to see in the dark. Knight featured in a number of adventure stories set in the 1930s. Other series he wrote included the "Eric Trent" series in Flying Aces and the Vanished Legion in Dare-Devil Aces, two long-running series: "The Devil Dog Squadron" in Sky Birds and "The Jailbird Flight" in Battle Aces. Many of Keyhoe's stories for the pulps were science fiction or Weird Fantasy, or contained a significant measure of these elements — a fact, not lost on critics of his UFO books.
He was a freelancer for Saturday Evening Post, The Nation, Reader's Digest. Following Kenneth Arnold's report of odd, fast-moving aerial objects in the summer of 1947, interest in "flying disks" and "flying saucers" was widespread, Keyhoe followed the subject with some interest, though he was skeptical of any extraordinary answer to the UFO question. For some time, True had been inquiring of officials as to the flying saucer question, with little to show for their efforts. In about May 1949, after the U. S. Air Force had released contradictory information about the saucers, editor Ken Purdy turned to Keyhoe, who had written for the magazine, but who importantly, had many friends and contacts in the military and the Pentagon. After some investigation, Keyhoe became convinced; as their forms, flight maneuvers and light technology was far ahead of any nation's developments, Keyhoe became convinced that they must be the products of unearthly intelligences, that the U. S. government was trying to suppress the whole truth about the subject.
This conclusion was based on the response Keyhoe found when he quizzed various officials about flying saucers. He was told there was nothing to the subject, yet was denied access to saucer-related documents. Keyhoe's article "Flying Saucers Are Real" appeared in the January 1950 issue of True and caused a sensation. Though such figures are always difficult to verify, Captain Edward J. Ruppelt, the first head of Project Blue Book, reported that "It is rumored among magazine publishers that Don Keyhoe's article in True was one of the most read and discussed magazine articles in history." Capitalizing on the interest, Keyhoe expanded the article into The Flying Saucers Are Real. He argued that the Air Force knew that flying saucers were extraterrestrial, but downplayed the reports to avoid public panic. In Keyhoe's view, the aliens — wherever their origins or intentions — did not seem hostile, had been surveilling the earth for two hundred years or more, though Keyhoe wrote that their "observation increased in 1947, following the series of A-bomb explosions in 1945."
Dr. Michael D. Swords characterized the book as "a rather sensational but accurate account of the matter." (Swords, p
United States Navy
The United States Navy is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U. S. allies or partner nations. With the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches, it has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second-largest air force in the world, after the United States Air Force. The U. S. Navy traces its origins to the Continental Navy, established during the American Revolutionary War and was disbanded as a separate entity shortly thereafter.
The U. S. Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers, it played the central role in the World War II defeat of Imperial Japan. The US Navy emerged from World War II as the most powerful navy in the world; the 21st century U. S. Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean, the Indian Ocean, it is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and respond to regional crises, making it a frequent actor in U. S. foreign and military policy. The Navy is administratively managed by the Department of the Navy, headed by the civilian Secretary of the Navy; the Department of the Navy is itself a division of the Department of Defense, headed by the Secretary of Defense. The Chief of Naval Operations is the most senior naval officer serving in the Department of the Navy.
The mission of the Navy is to maintain and equip combat-ready Naval forces capable of winning wars, deterring aggression and maintaining freedom of the seas. The U. S. Navy is a seaborne branch of the military of the United States; the Navy's three primary areas of responsibility: The preparation of naval forces necessary for the effective prosecution of war. The maintenance of naval aviation, including land-based naval aviation, air transport essential for naval operations, all air weapons and air techniques involved in the operations and activities of the Navy; the development of aircraft, tactics, technique and equipment of naval combat and service elements. U. S. Navy training manuals state that the mission of the U. S. Armed Forces is "to be prepared to conduct prompt and sustained combat operations in support of the national interest." As part of that establishment, the U. S. Navy's functions comprise sea control, power projection and nuclear deterrence, in addition to "sealift" duties, it follows as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, with it, everything honorable and glorious.
Naval power... is the natural defense of the United States The Navy was rooted in the colonial seafaring tradition, which produced a large community of sailors and shipbuilders. In the early stages of the American Revolutionary War, Massachusetts had its own Massachusetts Naval Militia; the rationale for establishing a national navy was debated in the Second Continental Congress. Supporters argued that a navy would protect shipping, defend the coast, make it easier to seek out support from foreign countries. Detractors countered that challenging the British Royal Navy the world's preeminent naval power, was a foolish undertaking. Commander in Chief George Washington resolved the debate when he commissioned the ocean-going schooner USS Hannah to interdict British merchant ships and reported the captures to the Congress. On 13 October 1775, the Continental Congress authorized the purchase of two vessels to be armed for a cruise against British merchant ships. S. Navy; the Continental Navy achieved mixed results.
In August 1785, after the Revolutionary War had drawn to a close, Congress had sold Alliance, the last ship remaining in the Continental Navy due to a lack of funds to maintain the ship or support a navy. In 1972, the Chief of Naval Operations, Admiral Elmo Zumwalt, authorized the Navy to celebrate its birthday on 13 October to honor the establishment of the Continental Navy in 1775; the United States was without a navy for nearly a decade, a state of affairs that exposed U. S. maritime merchant ships to a series of attacks by the Barbary pirates. The sole armed maritime presence between 1790 and the launching of the U. S. Navy's first warships in 1797 was the U. S.
