Melville W. Fuller
–
Melville Weston Fuller was the eighth Chief Justice of the United States from 1888 to his death in 1910. Fuller was born in Augusta, Maine, the son of Catherine Martin, both his maternal grandfather, Nathan Weston and paternal grandfather, Henry Weld Fuller were judges. His father was a well-known lawyer and his parents divorced shortly after his birth, and he was raised by Nathan Weston. He attended college at Harvard University for one year before graduating from Bowdoin College and he then spent six months at Harvard Law School, leaving without graduating in 1855. Fuller first studied law under the direction of an uncle, in 1855, he went into partnership with another uncle. He also became the editor of The Age, a leading Democratic newspaper in Augusta, soon he got tired of Maine and moved to Chicago. In 1860, he managed Democrat Stephen Douglas campaign for the Presidency of the United States At the time, railroads had just linked it to the east. Fuller built a law practice in Chicago, within two years, he appeared before the Supreme Court of Illinois in the case of Beach v. Derby. He became an attorney in the city. He first appeared before the United States Supreme Court in the case of Traders Bank v. Campbell. He also argued the case of Tappan v. the Merchants National Bank of Chicago, which was the first case heard by Chief Justice Morrison Waite and he was a minor figure in Illinois politics. In 1876, he made the speech for Thomas Hendricks. After his inauguration as President, Grover Cleveland tried to make Fuller chairman of the United States Civil Service Commission, Cleveland then tried to persuade Fuller to accept appointment as Solicitor General of the United States, but Fuller again declined. In 1886, Fuller was president of the Illinois State Bar Association, on April 30,1888, President Grover Cleveland nominated him for the chief justice position following the death of Morrison R. Waite. Fuller was not the first man to be mentioned as a possible Supreme Court nominee and he had avoided military service during the Civil War, and while serving in the Illinois House of Representatives had attempted to block wartime legislation proposed by Governor Richard Yates. However, he was confirmed by the United States Senate on July 20,1888, by a vote of 41 to 20. He received his commission the same day, Fuller did not take the oath of office until October 8,1888. On the bench, he oversaw a number of memorable or important opinions, the famous phrase Equal Justice Under Law paraphrases his opinion in Caldwell v. Texas,137 U. S.692 where Fuller discussed equal and impartial justice under the law

Cassiopeia (constellation)
–
Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivalled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy and it is easily recognizable due to its distinctive W shape, formed by five bright stars. It is opposite the Big Dipper, in northern locations above 34ºN latitude it is visible year-round and in the tropics it can be seen at its clearest from September to early November. Even in low southern latitudes below 25ºS it can be low in the North. At magnitude 2.2, Alpha Cassiopeiae, or Schedar, is generally the brightest star in Cassiopeia, though is often shaded by Gamma Cassiopeiae, which has brightened to magnitude 1.6 on occasion. The constellation hosts some of the most luminous stars known, including the yellow hypergiants Rho Cassiopeiae and V509 Cassiopeiae, the semiregular variable PZ Cassiopeiae is one of the largest known stars. In 1572, Tycho Brahes supernova flared brightly in Cassiopeia, fourteen star systems have been found to have exoplanets, one of which—HR 8832—is thought to host seven planets. The constellation is named after Cassiopeia, the queen of Aethiopia, Cassiopeia was the wife of King Cepheus of Aethiopia and mother of Princess Andromeda. Cepheus and Cassiopeia were placed next to each other among the stars, Andromeda was then rescued by the hero Perseus, whom she later married. Cassiopeia has been variously portrayed throughout her history as a constellation, in Persia, she was drawn by al-Sufi as a queen holding a staff with a crescent moon in her right hand, wearing a crown, as well as a two-humped camel. In France, she was portrayed as having a marble throne and this depiction is from Augustin Royers 1679 atlas. In the ancient Celtic world Anu was the goddess and considered to be the mother of all the gods. Other references say that she is the earth goddess or the Goddess of fertility. Anu was known, in the Celtic World, by similar names. She still looks down on us from the sky where she appears as Llys Don. In Chinese astronomy, the forming the constellation Cassiopeia are found among three areas, the Purple Forbidden enclosure, the Black Tortoise of the North, and the White Tiger of the West. The Chinese astronomers saw several figures in what is modern-day Cassiopeia, Kappa, Eta, and Mu Cassopeiae formed a constellation called the Bridge of the Kings, when seen along with Alpha and Beta Cassiopeiae, they formed the great chariot Wang-Liang. The charioteers whip was represented by Gamma Cassiopeiae, sometimes called Tsih, in the 1600s, various Biblical figures were depicted in the stars of Cassiopeia

Liberty ship
–
The Liberty ship was a class of cargo ship built in the United States during World War II. Though British in conception, the design was adapted by the United States for its simple, mass-produced on an unprecedented scale, the now iconic Liberty ship came to symbolize U. S. wartime industrial output. The class was developed to meet British orders for transports to replace those torpedoed by German U-boats, the vessels were purchased both for the U. S. fleet and lend-lease deliveries of war materiel to Britain and the Soviet Union. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945, easily the largest number of ships produced to a single design and their production mirrored on a much larger scale the manufacture of the Hog Islander and similar standardized ship types during World War I. Only three Liberty Ships are preserved, two as operational museum ships. S, the number was doubled in 1939 and again in 1940 to 200 ships a year. Ship types included two tankers and three types of merchant vessel, all to be powered by steam turbines, limited industrial capacity, especially for reduction gears, meant that relatively few of these ships were built. In 1940 the British government ordered 60 Ocean-class freighters from American yards to replace war losses and these were simple but fairly large with a single 2,500 horsepower compound steam engine of obsolete but reliable design. Britain specified coal-fired plants, because it then had extensive coal mines, the order specified an 18-inch increase in draft to boost displacement by 800 long tons to 10,100 long tons. The accommodation, bridge, and main engine were located amidships, the first Ocean-class ship, SS Ocean Vanguard, was launched on 16 August 1941. The design was modified by the United States Maritime Commission, in part to increase conformity to American construction practices, but more importantly to make it even quicker and cheaper to build. The US version was designated EC2-S-C1, EC for Emergency Cargo,2 for a ship between 400 and 450 feet long, S for steam engines, and C1 for design C1. The new design replaced much riveting, which accounted for one-third of the costs, with welding. It was adopted as a Merchant Marine Act design, and production awarded to a conglomerate of West Coast engineering and construction companies headed by Henry J. Kaiser known as the Six Companies. Liberty ships were designed to carry 10,000 long tons of cargo, usually one type per ship, but, during wartime, generally carried loads far exceeding this. On 27 March 1941, the number of ships was increased to 200 by the Defense Aid Supplemental Appropriations Act and increased again in April to 306. By 1941, the turbine was the preferred marine steam engine because of its greater efficiency compared to earlier reciprocating compound steam engines. Eighteen different companies built the engine. It had the advantage of ruggedness and simplicity

Maritime Commission
–
It also formed the United States Maritime Service for the training of seagoing ships officers to man the new fleet. The purpose of the Maritime Commission was multifold as described in the Merchant Marine Acts Declaration of Policy. S, Merchant Marine prior to the Act. Another function given to the Commission involved the formation of the U. S. Maritime Service for the training of seagoing ships officers to man the new fleet, the actual licensing of officers and seamen still resided with the Bureau of Marine Inspection and Navigation. President Roosevelt nominated Joseph P. Kennedy first head of the Commission, Kennedy held that position until February 1938 when he left to become US Ambassador to Great Britain. The other four members of the Commission in the years before the beginning of World War II were a mix of retired officers and men from disciplines of law. The man most notable in the group Land brought to the Commission was Commander Howard L. Vickery, USN, as a symbol of the rebirth of the U. S. Upon the U. S. entry into World War II, America was requisitioned by the U. S. Navy and became USS West Point. Most of the C2s and C3s were converted to Navy auxiliaries, notably attack cargo ships, attack transports, the Commission also was tasked with the construction of many hundred military type vessels such as Landing Ship, Tank s and Tacoma-class frigates and large troop transports. By the end of the war, U. S. shipyards working under Maritime Commission contracts had built a total of 5,777 oceangoing merchant, in early 1942 both the training and licensing was transferred to the U. S. S. With the end of World War II, both the Emergency and Long Range shipbuilding programs were terminated as there were far too many merchant vessels now for the Nations peacetime needs. In 1946, the Merchant Ship Sales Act was passed to sell off a portion of the ships previously built during the war to commercial buyers. Although not sold outright to nations that were enemies during the war, for the next 25 years, in ports all around the world one could find dozens of ships which had been built during the war but which now were used in peace. Ships not disposed of through the Ship Sales Act were placed one of eight National Defense Reserve Fleet sites maintained on the Atlantic, Pacific. On several occasions in the postwar years ships in the fleets were activated for both military and humanitarian aid missions. The last major mobilization of the NDRF came during the Vietnam War, since then, a smaller fleet of ships called the Ready Reserve Force has been mobilized to support both humanitarian and military missions. The Maritime Commission was abolished on 24 May 1950, and its functions were divided between the U. S. S. Merchant Marine Academy which had built and opened during World War II. 1936, Merchant Marine Act abolishes Shipping Board and establishes Maritime Commission,1937, Joseph P. S. merchant shipping has been held by many agencies since 1917

Richmond, California
–
Richmond is a city in western Contra Costa County, California, United States. The city was incorporated on August 7,1905, under the McLaughlin Administration, Richmond was the largest city in the United States served by a Green Party mayor. As of the 2010 U. S. Census, the population is at 103,710. The largest, Richmond, Virginia, is the namesake of the California city, the Ohlone Indians were the first inhabitants of the Richmond area, settling an estimated 5,000 years ago. The name Richmond appears to predate actual incorporation by more than fifty years, the Atchison, Topeka and Santa Fe Railroad had its terminus at Richmond. The first post office opened in 1900, Richmond was founded and incorporated in 1905, carved out of Rancho San Pablo, from which the nearby town of San Pablo inherited its name. Until the enactment of prohibition in 1919, the city had the largest winery in the world, in the 1920s the Ku Klux Klan was active in the city. In 1930 the Ford Motor Company opened a plant called Richmond Assembly Plant which moved to Milpitas in the 1960s. The old Ford plant has been a National Historic Place since 1988, the city was a small town at that time, until the onset of World War II which brought on a rush of migrants and a boom in the industrial sector. Standard Oil set up here in 1901, including a what is now the Chevron Richmond Refinery and tank farm. There is a pier into San Francisco Bay south of Point Molate for oil tankers, the western terminus of the Santa Fe Railroad was established in Richmond with ferry connections at Ferry Point in the Brickyard Cove area of Point Richmond to San Francisco. Many of these lived in specially constructed houses scattered throughout the San Francisco Bay Area, including Richmond, Berkeley. A specially built rail line, the Shipyard Railway, transported workers to the shipyards, kaisers Richmond shipyards built 747 Victory and Liberty ships for the war effort, more than any other site in the U. S. The city broke many records and even built one Liberty ship in a five days. On average the yards could build a ship in thirty days, the medical system established for the shipyard workers at the Richmond Field Hospital eventually became todays Kaiser Permanente HMO. It remained in operation until 1993 when it was replaced by the modern Richmond Medical Center hospital, Point Richmond was originally the commercial hub of the city, but a new downtown arose in the center of the city. It was populated by many department stores such as Kress, J. C. Penney, Sears, Macys, during the war the population increased dramatically and peaked at around 120,000 by the end of the war. Once the war ended the workers were no longer needed

International Code of Signals
–
The International Code of Signals is an international system of signals and codes for use by vessels to communicate important messages regarding safety of navigation and related matters. Signals can be sent by flaghoist, signal lamp, flag semaphore, radiotelegraphy, the International Code is the most recent evolution of a wide variety of maritime flag signalling systems. It has done this by first establishing an alphabet, along with a spoken form of each letter. Combinations of these characters are assigned as codes for various standardized messages. One simply raises the Kilo flag, or sends the Morse Code equivalent by flashing light, one of the elegant aspects of the ICS is that all of the standardized messages come in nine languages. It is immaterial if the sender and receiver are using different languages, the code also covers procedural aspects, how naval ships indicate that they are using the ICS, use in radiotelephony, and various other matters. Prior to 1969, the code was more extensive, covering a wider range of messages. Since 1969, it has reduced to focus on navigation and safety. Signals can be sorted into three groups, Single-letter signals which are very urgent, important, or common, two-letter signals for other messages, sometimes followed with a numerical complement which supplements or modifies the message. Three-letter signals beginning with M, these are the Medical Signal Codes, in some cases, additional characters are added to indicate quantities, bearing, course, distance, date, time, latitude, or longitude. There is also provision for spelling words and for indicating use of other codes, several of the more common single-letter signals are shown at the right. Two-letter signals cover a broad gamut of situations, the reader is urged to download a copy of the Code from the link below. Repeated characters can be a problem in flaghoist, to avoid having to carry multiple sets of signal flags, the Code uses three substitute flags. These repeat the flag at the indicated position, for instance, to signal MAA the Mike, Alfa, and 2nd substitute flags would be flown, the substitute indicating a repeat of the second character. The Medical Signal Code is a means of providing assistance when medical personnel are not present, even where there are no language problems, the Medical Signal Code is useful in providing a standard method of case description and treatment. There is also a standard list of medicaments, keyed to a standard ships medicine chest carried by all merchant ships, the Medical signals all begin with the letter M followed by two more letters, and sometimes with additional numerals or letters. The International Code of Signals was preceded by a variety of signals and private signals, most notably Marryats Code. What is now the International Code of Signals was drafted in 1855 by the British Board of Trade and it came in two parts, the first containing universal and international signals, and the second British signals only

Battle star
–
The service star may also be referred to as a campaign star or battle star depending on which award is authorized the star and the manner in which the device is used for the award. Service stars, Campaign stars, and Battle stars are worn with one point of the star pointing up on the ribbon of a medal. A silver star is worn instead of five bronze stars, a service star is sometimes mistaken for a Bronze Star or Silver Star. The service star is similar to the gold and silver 5⁄16 Inch Stars which may be authorized to be worn on specific individual decorations of certain services to denote additional decorations. Service stars are authorized for the following United States expeditionary medals, Armed Forces Expeditionary Medal, Navy Expeditionary Medal, Service stars are also authorized for the Global War on Terrorism Expeditionary Medal effective February 9,2015 retroactive to September,11,2001. Each star represents a deployment in support of an approved GWOT operation, only one GWOT-EM is awarded for each operation. The five GWOT-EM approved operations by inclusive dates are, Enduring Freedom,11,2001 - TBD Iraqi Freedom, Mar.19,2003 - Aug.31, 2010Nomad Shadow, Nov.05,2007 - TBD New Dawn, Sep. 01,2010 - Dec.31,2011 Inherent Resolve, the bronze service star is also authorized for certain unit awards such as the Presidential Unit Citation to denote a second and subsequent award. The service ribbon itself indicates the first award, with a service star being added to indicate the second. If ever applicable, a service star is worn instead of five bronze stars. As a result, at least one star will be worn on the ribbon. However, though authorized for wear, no battle stars have been approved for wear, only a combatant commander can initiate a request for a battle star. The Chairman of the Joint Chiefs of Staff is the approving authority, only one award of the Global War on Terrorism Expeditionary Medal and one award of the Global War on Terrorism Service Medal may be authorized for any individual. The specific manner of wear and symbolism of the stars varied from medal to medal, for example, an American Campaign Medal with a bronze service star indicated the service member had participated in an antisubmarine campaign. On other medals, bronze service stars were used on the service ribbon for those recipients of medals in possession of authorized campaign claps for those medals. Similarly, during the Vietnam War and afterwards, the Battle Effectiveness Award took the place of receiving battle stars for superior battle efficiency in place of combat operations.

National Defense Reserve Fleet
–
The NDRF is managed by the U. S. Department of Transportations Maritime Administration. It is a different entity from the United States Navy reserve fleets, NDRF vessels are at the fleet sites at James River, Virginia–the James River Reserve Fleet, Beaumont, Texas–the Beaumont Reserve Fleet, and Suisun Bay, California, and at designated outported berths. Former anchorage sites included Stony Point, New York - the Hudson River Reserve Fleet, Wilmington, North Carolina, Mobile, Alabama, Astoria, Oregon, and Olympia, Washington. Through the 2010s, the oldest, most decrepit hulls at Suisun Bay will be stripped of materials, then broken up in Texas. Twenty of the most polluting mothball ships are slated for recycling by 2012, at its peak in 1950, the NDRF had 2,277 ships in lay-up. In July 2007, it held 230 ships, primarily dry cargo ships with some tankers, military auxiliaries, by the end of August,2015, it held 100. The NDRF was established under Section 11 of the Merchant Ship Sales Act of 1946 to serve as a reserve of ships for national defense, NDRF vessels were used in seven wars and crises. During the Korean War,540 vessels were out to move military forces. During a worldwide tonnage shortfall in 1951–53, more than 600 ships were reactivated to carry coal to Northern Europe, from 1955 through 1964, another 600 ships were used to store grain for the Department of Agriculture. Another 223 cargo ships and 29 tankers were activated during a tonnage shortfall after the Suez Canal was closed in 1956, during the Berlin crisis of 1961,18 vessels were activated and remained in service until 1970. Another 172 vessels were activated for the Vietnam War and these are crewed with a reduced crew but kept available for activation within four, five, ten or twenty days. An additional 28 ships are held under United States Maritime Administration custody for other Government agencies on a cost-reimbursable basis. Vessels with military utility or logistic value are held in status and are in a preservation program that is designed to keep them in the same condition as when they enter the fleet. The internal spaces are dehumidified to slow the corrosion of metal, DC power is distributed through anodes to the exterior underwater portions of the hull, creating an electric field that suppresses corrosion and preserves the surface of the hull. External painting and other work is generally deferred since it does not affect the ability to activate and operate the vessel. MARAD is authorized as the government’s disposal agent through the NDRF program for merchant type vessels equal to or greater than 1,500 gross tons. A state agency can file an application to request title to a vessel as-is where-is from the NDRF for the purpose of creating an artificial reef, of the 132 non-retention vessels in the NDRF, there are 117 that are being prepared for disposal. The NDRF program can give and lend historic artifacts to maritime-heritage organizations, battleships, cruisers, and aircraft carriers which have been stricken or those awaiting final disposition may be transferred to MARAD locations for berthing

James River
–
The James River is a river in the U. S. state of Virginia. It is 348 miles long, extending to 444 miles if one includes the Jackson River, the James River drains a catchment comprising 10,432 square miles. The watershed includes about 4% open water and an area with a population of 2.5 million people and it is the 12th longest river in the United States that remains entirely within a single state. Tidal waters extend west to Richmond, the capital of Virginia, larger tributaries draining to the tidal portion include the Appomattox River, Chickahominy River, Warwick River, Pagan River, and the Nansemond River. At its mouth near Newport News Point, the Elizabeth River, many boats pass through this river to import and export Virginia products. The navigable portion of the river was the highway of the Colony of Virginia during its first 15 years, facilitating supply ships delivering supplies. However, for the first five years, despite many hopes of gold and riches, in 1612, businessman John Rolfe successfully cultivated a non-native strain of tobacco which proved popular in England. Soon, the became the primary means of exporting the large hogsheads of this cash crop from an ever-growing number of plantations with wharfs along its banks. This development made the efforts of the Virginia Company of London successful financially, spurring even more development, investments. The upper reaches of the river above the head of navigation at the line were explored by fur trading parties sent by Abraham Wood during the late 17th century. Although ocean-going ships were unable to navigate beyond present-day Richmond, portage of products, produce from the Piedmont and Great Valley regions traveled down the river to seaports at Richmond and Manchester through such port towns as Lynchburg, Scottsville, Columbia and Buchanan. The James River was considered as a route for transport of produce from the Ohio Valley, the James River and Kanawha Canal was built for this purpose, to provide a navigable portion of the Kanawha River, a tributary of the Ohio River. For the most mountainous section between the two points, the James River and Kanawha Turnpike was built to provide a link via wagons. However, before the canal could be completed, in the mid-19th century, railroads emerged as a more practical technology. The Chesapeake and Ohio Railway was completed between Richmond and the Ohio River at the new city of Huntington, West Virginia by 1873, dooming the canals economic prospects. In the 1880s, the Richmond and Alleghany Railroad was laid along the portion of the canals towpath. In modern times, this line is used primarily in transporting West Virginia coal to export coal piers at Newport News. The James River contains numerous parks and other recreational attractions, canoeing, fishing, kayaking, hiking, and swimming are some of the activities that people enjoy along the river during the summer

Lee Hall, Virginia
–
Lee Hall is a former unincorporated town long located in the former Warwick County. Since 1958, Lee Hall has been a community in the extreme western portion of the independent city of Newport News in the Commonwealth of Virginia. The mansion was used as headquarters for Confederate generals Joseph E. Johnston, magruder during the Peninsula Campaign of the American Civil War in 1862. Nearby is Endview Plantation, a 238-year-old house, Endview was used as a hospital during the Civil War and as a campground during the Revolutionary War, the War of 1812 and the Civil War. The Boxwood Inn was built in 1897, Lee Hall Depot became a very busy railroad station after the establishment nearby of Fort Eustis in 1918, with freight and heavy troop movements. The busy activity resumed during World War II and it was expanded to accommodate this role. East of Lee Hall, a spur leads to the base. With the coming of the automobile as a form of travel in the early 20th century. As part of the Good Roads Movement, the new road which became U. S. Route 60 was routed from Williamsburg through Grove and this routing was chosen rather than following a competing route via Halsteads Point in York County. Earlier, the east-west road which became U. S.60 was State Route 9, SR9 was renumbered as State Route 39 in 1923, and became U. S.60 in the mid-1920s when it was routed through Grove. The village portion of Lee Hall is connected to I-64 via State Route 238, the 26th Balloon Company of the US Army Air Corps had a training school at Lee Hall at least during the summer of 1920 training soldiers for deployment to central and South America service. In the 21st century, Lee Hall Depot is the only surviving C&O structure of its type on the Lower Peninsula. Across the street from the Depot, the Boxwood Inn, a bed and breakfast establishment in an 1896 house, is open and available for overnight visitors and some meals. The citys tourism agency operates several other attractions at Lee Hall Mansion and Endview Plantation, the Lee Hall community is served by exit 247 of Interstate 64. About 1 block from the railroad station, U. S. Route 60. Lee Hall is served by both Hampton Roads Transit and Williamsburg Area Transit Authority, for direct service to the Williamsburg Amtrak and Greyhound/Carolina Trailways station, ride the WATA Grey Line to the Williamsburg Transportation Center. For service to the Newport News Amtrak station, ride the 116 and transfer to the 106 or 107 to get to the Newport News Amtrak station

USS Cutlass (SS-478)
–
Her keel was laid down by the Portsmouth Navy Yard on 10 July 1944. She was launched on 5 November 1944 sponsored by Mrs. R. E. Kintner, departing Portsmouth, New Hampshire, on 25 April 1945, Cutlass arrived at Pearl Harbor on 15 July and put out on her maiden war patrol two days later. Assigned to patrol in the vicinity of the Kurile Islands, she entered the one day after the Japanese surrender, remained on observation patrol until 24 August. She sailed on 2 September for New York, arriving 24 September to receive visitors through Navy Day, Cutlass cruised on the East Coast until 8 January 1946 when she cleared for the Panama Canal Zone. Except for three months of operations in Delaware Bay, Cutlass remained in the Caribbean Sea, based at Cristóbal, Canal Zone. Cutlass left the Panama Canal Zone 6 January 1948 for local operations at Key West, Florida, then entered Philadelphia Naval Shipyard in March for overhaul and she continued to sail out of Key West until the summer of 1952 when her home port was changed to Norfolk, Virginia. She visited Italy, Greece, Crete, Majorca, Portugal and England, in 1958 she sailed on a north European cruise, visiting Rosyth, Scotland, Copenhagen and Korsor, Denmark, and passing through the Kiel Canal. In the first half of 1959, Cutlass joined in the antisubmarine warfare development work of Task Force Alfa off the Virginia Capes, in November she passed through the Suez Canal to join ships of the Pakistani Navy in exercises off Karachi, returning to Norfolk in December. After continued operations with TF Alfa, she entered Philadelphia Naval Shipyard in February 1960 for an overhaul which continued until August, Cutlass was decommissioned and struck from the Naval Vessel Register on 15 April 1973. On 4 December 1973, Cutlass had her torpedo tubes sealed and was sold to Taiwan, in January 2017, Taiwan announced that it would receive a retrofit to extend its service life until 2026, making it the longest-serving submarine in history. The submarine is still operational and reportedly capable of combat, the $19 million retrofit will be to improve the hull and the diesel vessels navigational elements.

Cargo ship
–
A cargo ship or freighter is any sort of ship or vessel that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the worlds seas and oceans each year, cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built by welded steel, cargo ships/freighters can be divided into five groups, according to the type of cargo they carry. Tankers carry petroleum products or other liquid cargo, dry bulk carriers carry coal, grain, ore and other similar products in loose form. Multi-purpose vessels, as the name suggests, carry different classes of cargo – e. g. liquid, a Reefer ship is specifically designed and used for shipping perishable commodities which require temperature-controlled, mostly fruits, meat, fish, vegetables, dairy products and other foodstuffs. Specialized types of cargo vessels include ships and bulk carriers. Cargo ships fall into two categories that reflect the services they offer to industry, liner and tramp services. Those on a published schedule and fixed tariff rates are cargo liners. Tramp ships do not have fixed schedules, users charter them to haul loads. Generally, the shipping companies and private individuals operate tramp ships. Cargo liners run on fixed schedules published by the shipping companies, each trip a liner takes is called a voyage. However, some cargo liners may carry passengers also, a cargo liner that carries 12 or more passengers is called a combination or passenger-cum-cargo line. The desire to trade routes over longer distances, and throughout more seasons of the year. Before the middle of the 19th century, the incidence of piracy resulted in most cargo ships being armed, sometimes heavily, as in the case of the Manila galleons. They were also escorted by warships. Piracy is still common in some waters, particularly in the Malacca Straits. In 2004, the governments of three nations agreed to provide better protection for the ships passing through the Straits. The waters off Somalia and Nigeria are also prone to piracy, while smaller vessels are also in danger along parts of the South American, Southeast Asian coasts, the words cargo and freight have become interchangeable in casual usage

Babcock & Wilcox boiler
–
A watertube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes, in smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water rises into the steam drum. Here, saturated steam is drawn off the top of the drum, in some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the point at a given pressure. Superheated steam is a dry gas and therefore used to drive turbines, cool water at the bottom of the steam drum returns to the feedwater drum via large-bore downcomer tubes, where it pre-heats the feedwater supply. To increase economy of the boiler, exhaust gases are used to pre-heat the air blown into the furnace. Such watertube boilers in thermal power stations are called steam generating units.4 MPa. A water tube boiler was patented by Blakey of England in 1766 and was made by Dallery of France in 1780. e, approximately 16 megapascals and high temperatures reaching up to 550 °C are generally required. For example, the Ivanpah solar-power station uses two Rentech Type-D watertube boilers, modern boilers for power generation are almost entirely water-tube designs, owing to their ability to operate at higher pressures. Where process steam is required for heating or as a chemical component and their ability to work at higher pressures has led to marine boilers being almost entirely water-tube. This change began around 1900, and traced the adoption of turbines for propulsion rather than reciprocating engines – although watertube boilers were used with reciprocating engines. There has been no significant adoption of water-tube boilers for railway locomotives, a handful of experimental designs were produced, but none of these were successful or led to their widespread use. Most water-tube railway locomotives, especially in Europe, used the Schmidt system, most were compounds, and a few uniflows. The Norfolk and Western Railways Jawn Henry was an exception, as it used a steam turbine combined with an electric transmission, LMS6399 Fury Rebuilt completely after a fatal accident LNER10000 Hush hush Using a Yarrow boiler, rather than Schmidt. Never successful and re-boilered with a conventional boiler, a slightly more successful adoption was the use of hybrid water-tube / fire-tube systems. As the hottest part of a boiler is the firebox, it was an effective design to use a water-tube design here. One famous example of this was the USA Baldwin 4-10-2 No, operating as a compound at a boiler pressure of 2,400 kilopascals it covered over 160,000 kilometres successfully

Horsepower
–
Horsepower is a unit of measurement of power. There are many different standards and types of horsepower, two common definitions being used today are the mechanical horsepower, which is approximately 746 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of engines with the power of draft horses. It was later expanded to include the power of other types of piston engines, as well as turbines, electric motors. The definition of the unit varied among geographical regions, most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1,2010, units called horsepower have differing definitions, The mechanical horsepower, also known as imperial horsepower equals approximately 745.7 watts. It was defined originally as exactly 550 foot-pounds per second [745.7 N. m/s), the metric horsepower equals approximately 735.5 watts. It was defined originally as 75 kgf-m per second is approximately equivalent to 735.5 watts, the Pferdestärke PS is a name for a group of similar power measurements used in Germany around the end of the 19th century, all of about one metric horsepower in size. The boiler horsepower equals 9809.5 watts and it was used for rating steam boilers and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit. One horsepower for rating electric motors is equal to 746 watts, one horsepower for rating Continental European electric motors is equal to 735 watts. Continental European electric motors used to have dual ratings, one British Royal Automobile Club horsepower can equal a range of values based on estimates of several engine dimensions. It is one of the tax horsepower systems adopted around Europe, the development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them. He had previously agreed to take royalties of one third of the savings in coal from the older Newcomen steam engines and this royalty scheme did not work with customers who did not have existing steam engines but used horses instead. Watt determined that a horse could turn a mill wheel 144 times in an hour, the wheel was 12 feet in radius, therefore, the horse travelled 2.4 × 2π ×12 feet in one minute. Watt judged that the horse could pull with a force of 180 pounds-force. So, P = W t = F d t =180 l b f ×2.4 ×2 π ×12 f t 1 m i n =32,572 f t ⋅ l b f m i n. Watt defined and calculated the horsepower as 32,572 ft·lbf/min, Watt determined that a pony could lift an average 220 lbf 100 ft per minute over a four-hour working shift. Watt then judged a horse was 50% more powerful than a pony, engineering in History recounts that John Smeaton initially estimated that a horse could produce 22,916 foot-pounds per minute

Hooven-Owens-Rentschler
–
The firm of Hooven, Owens, Rentschler, and Company manufactured steam and diesel engines in Hamilton, Ohio. Because the firm was known by its initials, H. O. R. The Hooven is sometimes rendered as Hoover, and the Owens may be mistaken for Owen. The firm was the successor to the firm of Owens, Ebert & Dyer which went into receivership in 1876, in 1882, George A. Rentschler, J. C. Sohn, George H. Helvey, and James E. Campbell merged the firm with the works of Sohn and Rentschler. In 1883 the firm began the manufacture of Corliss steam engines, by World War I, the Hooven-Owens-Rentschler Company operated the largest exclusive Corliss Engine plant in the country, employing nearly 800 men. In 1928 the company merged with the Niles Tool Works to form the General Machinery Corporation, however, it continued to make diesel engines under the H. O. R. Brand, and supplied many of the powerplants for United States submarines, General Machinery Corporation ranked 91st among United States corporations in the value of World War II military production contracts. The double-acting design produced more power from a smaller engine than conventional designs. However, H. O. R. s double-acting engines, particularly those of USS Pompano, gained notoriety for their unreliability in the submarine force, during World War II, all submarine H. O. R. Engines were replaced by early 1943, usually with General Motors Cleveland Division engines or Fairbanks-Morse Model 38 engines, BLH, Hamilton Div. moved to the Eddystone Pa. plant of BLH in 1959. BLH went out of business around 1966, an HOR combination steam engine is preserved in the Henry Ford Museum in Dearborn, Michigan. It is one of 12 units that were made for Mr. Ford for his Highland Park assembly plant where he produced the Model T from 1908 until its demise in 1927. This engine was removed from the Highland Park facility and placed in storage after the Ford Motor Company took up permanent residence at the giant River Rouge facilities to produce the Model A, Mr. Ford donated the steam engine to his Edison Institute as the cornerstone display in 1929. The Edison Institute later was renamed the Henry Ford Museum and is today as The Henry Ford

Triple-expansion engines
–
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are combustion engines, where the working fluid is separated from the combustion products. Non-combustion heat sources such as power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle, in the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done, the reduced-pressure steam is then exhausted to the atmosphere, or condensed and pumped back into the boiler. Specialized devices such as hammers and steam pile drivers are dependent on the steam pressure supplied from a separate boiler. The use of boiling water to mechanical motion goes back over 2000 years. The Spanish inventor Jerónimo de Ayanz y Beaumont obtained the first patent for an engine in 1606. In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped, Saverys steam pump used condensing steam to create a vacuum and draw water into a chamber, and then applied pressurized steam to further pump the water. Thomas Newcomens atmospheric engine was the first commercial steam engine using a piston. In 1781 James Watt patented an engine that produced continuous rotary motion. Watts ten-horsepower engines enabled a range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained, by 1883, engines that could provide 10,000 hp had become feasible. The stationary steam engine was a key component of the Industrial Revolution, the aeolipile described by Hero of Alexandria in the 1st century AD is considered to be the first recorded steam engine. Torque was produced by steam jets exiting the turbine, in the Spanish Empire, the great inventor Jerónimo de Ayanz y Beaumont obtained a patent for the first steam engine in history in 1603. Thomas Savery, in 1698, patented the first practical, atmospheric pressure and it had no piston or moving parts, only taps. It was an engine, a kind of thermic syphon, in which steam was admitted to an empty container. The vacuum thus created was used to water from the sump at the bottom of the mine

Drive shaft
–
As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia. The term drive shaft first appeared during the mid 19th century, in Stovers 1861 patent reissue for a planing and matching machine, the term is used to refer to the belt-driven shaft by which the machine is driven. The term is not used in his original patent, another early use of the term occurs in the 1861 patent reissue for the Watkins and Bryson horse-drawn mowing machine. Here, the term refers to the transmitting power from the machines wheels to the gear train that works the cutting mechanism. In the 1890s, the term began to be used in a closer to the modern sense. In 1899, Bukey used the term to describe the shaft transmitting power from the wheel to the machinery by a universal joint in his Horse-Power. In the same year, Clark described his Marine Velocipede using the term to refer to the shaft transmitting power through a universal joint to the propeller shaft. Crompton used the term to refer to the shaft between the transmission of his steam-powered Motor Vehicle of 1903 and the driven axle, an automobile may use a longitudinal shaft to deliver power from an engine/transmission to the other end of the vehicle before it goes to the wheels. A pair of short drive shafts is commonly used to power from a central differential, transmission. In front-engined, rear-drive vehicles, a drive shaft is also required to send power the length of the vehicle. Two forms dominate, The torque tube with a universal joint. This system became known as Système Panhard after the automobile company Panhard et Levassor patented it, most of these vehicles have a clutch and gearbox mounted directly on the engine, with a drive shaft leading to a final drive in the rear axle. When the vehicle is stationary, the drive shaft does not rotate, some vehicles, seeking improved weight balance between front and rear, use a rear-mounted transaxle. This places the clutch and transmission at the rear of the car, in this case the drive shaft rotates continuously with the engine, even when the car is stationary and out of gear. A drive shaft connecting a rear differential to a wheel may be called a half-shaft. The name derives from the fact that two such shafts are required to one rear axle. Early automobiles often used chain drive or belt drive mechanisms rather than a drive shaft, some used electrical generators and motors to transmit power to the wheels

Knot (unit)
–
The knot is a unit of speed equal to one nautical mile per hour, approximately 1.151 mph. The ISO Standard symbol for the knot is kn, the same symbol is preferred by the IEEE, kt is also common. The knot is a unit that is accepted for use with the SI. Etymologically, the term derives from counting the number of knots in the line that unspooled from the reel of a log in a specific time. 1 international knot =1 nautical mile per hour,1.852 kilometres per hour,0.514 metres per second,1.151 miles per hour,20.254 inches per second,1852 m is the length of the internationally agreed nautical mile. The US adopted the definition in 1954, having previously used the US nautical mile. The UK adopted the international nautical mile definition in 1970, having used the UK Admiralty nautical mile. The speeds of vessels relative to the fluids in which they travel are measured in knots, for consistency, the speeds of navigational fluids are also measured in knots. Thus, speed over the ground and rate of progress towards a distant point are given in knots. Until the mid-19th century, vessel speed at sea was measured using a chip log, the chip log was cast over the stern of the moving vessel and the line allowed to pay out. Knots placed at a distance of 8 fathoms -47 feet 3 inches from each other, passed through a sailors fingers, the knot count would be reported and used in the sailing masters dead reckoning and navigation. This method gives a value for the knot of 20.25 in/s, the difference from the modern definition is less than 0. 02%. On a chart of the North Atlantic, the scale varies by a factor of two from Florida to Greenland, a single graphic scale, of the sort on many maps, would therefore be useless on such a chart. Recent British Admiralty charts have a latitude scale down the middle to make this even easier, speed is sometimes incorrectly expressed as knots per hour, which is in fact a measure of acceleration. Prior to 1969, airworthiness standards for aircraft in the United States Federal Aviation Regulations specified that distances were to be in statute miles. In 1969, these standards were amended to specify that distances were to be in nautical miles. At 11000 m, an airspeed of 300 kn may correspond to a true airspeed of 500 kn in standard conditions.

Deadweight tonnage
–
Deadweight tonnage or tons deadweight is a measure of how much mass a ship is carrying or can safely carry, it does not include the weight of the ship. DWT is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, DWT is often used to specify a ships maximum permissible deadweight, although it may also denote the actual DWT of a ship not loaded to capacity. Deadweight tonnage is a measure of a weight carrying capacity. It should not be confused with displacement which includes the ships own weight, nor other volume or capacity measures such as gross tonnage or net tonnage

5"/38 caliber gun
–
The Mark 12 5/38 caliber gun was a US naval gun. The gun was installed into Single Purpose and Dual Purpose mounts used primarily by the US Navy, 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. The increased barrel length provided greatly 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, which enabled rapid fire at high angles against aircraft, the 5/38 entered service on USS Farragut, commissioned in 1934. The base ring mount, which improved the rate of fire, entered service on USS Gridley. Even this advanced system required nearly 100 rounds of ammunition expenditure per aircraft kill, however, the planes were normally killed by shell fragments and not direct hits, barrage fire was used, with many guns firing in the air at the same time. Base ring mounts with integral hoists had a rate of fire of 15 rounds per minute per barrel, however. 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 and it has left active US Navy service, but it is still on mothballed ships of the United States Navy reserve fleets. It is also used by a number of nations who bought or were given US Navy surplus ships, each mount carries one or two Mk 12 5/38cal Gun Assemblies. The gun assembly shown is used in single mounts, and it is the 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, and it is loaded from the right side. The Mk12 gun assembly weighs 3,990 lb, 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 energy is used during counter-recoil to prepare the gun for the next round, the firing pin is cocked, the breech is opened, the spent powder case is ejected, and the bore is air cleaned. Hand loaded A Projectile-Man and a Powder-Man are stationed at each gun assembly and their job is to move the round, consisting of a projectile and a powder case, from the hoists to the rammer tray, and then start the ram cycle. 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 is confusing, look at this footnote. Vertical sliding-wedge breech block The breech block closes the chamber behind the powder case and it also holds the firing pin assembly

Caliber (artillery)
–
In artillery, caliber or calibre is the internal diameter of a gun barrel, or by extension a relative measure of the length. Rifled barrels introduce ambiguity to measurement of caliber, a rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land, the depth of rifling grooves increases in larger calibers. United States Navy guns typically used rifling depth between one-half and one percent of caliber, projectile bourrelet diameter specification was 0.015 inches less than land to land diameter with a minus manufacturing tolerance so average clearance was about 0.012 inches. Driving band diameter was groove to groove diameter plus 0.02 inches, the length of the barrel is often quoted in calibers. For example, US Naval Rifles 3 in or larger, the effective length of the barrel is divided by the barrel diameter to give a dimensionless quantity.81 As an example, the main guns of the Iowa-class battleships can be referred to as 16/50 caliber. They are 16 inches in diameter and the barrel is 800 inches long, the bore to barrel length ratio is called caliber in naval gunnery,81 but is called length in army artillery. Before World War II, the US Navy used 5/51 caliber as surface-to-surface guns, by the end of World War II, the dual purpose 5/38 caliber was standard naval armament against surface and air targets. All three had a diameter of 5 inches. At sea, a weapon had to perform, without fail, there was no ready replacement, nor one that could be readily supplied. Over time, the terms of pound and bore became confused and blurred, eventually, when the technology existed, the bore came to be the standard measure. For naval rifles, the change was to actual bore. They then began to measure the length of the weapon in calibers. These were a measure of the bore of the barrel versus the rifled bore of the barrel. In other words, a 12/45 is 12×45= the length of the bore of that gun in inches. This explains the differences in both penetration and long range performance of naval rifles over the years. In addition to the improvements in overall performance, the increase in barrel length also allowed, in some circumstances. For example, the American 14/45, as introduced in the New York-class battleships, later improvements to the design, lengthening the rifle itself and also altering the breech, allowed a 1400 lb. projectile and, overall, a greater barrel life
22.
Dual-purpose gun
–
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets. The light A/A was dispersed throughout the ship and included both automatic cannons and heavy machine guns and they discarded the dedicated, anti-ship secondary batteries altogether, because a battle-line fleet would be screened against cruiser and destroyers most of the time. Rather, they replaced them with turret-mounted dual-purpose guns that could be used against both aircraft and ships and this arrangement was seen as more efficient, and was deemed adequate to meet anti-surface and anti-aircraft needs under most circumstances. Both navies were concerned of close-range torpedo attacks from enemy destroyers and torpedo boats, the French Navy used a mixed-calibre system, as well, but their secondary battery was dual-purpose. This tended to complicate ammunition supplies and render certain armament useless in some situations, dual-purpose guns are designed as a compromise between the heavy main armament of a surface combatant and dedicated anti-aircraft guns. Usually of a caliber, the gun is heavy enough to prove useful against surface targets including ships, surfaced submarines. For example, a Royal Navy battleship of the King George V class had sixteen QF Mark I5. 25-inch guns that could engage enemy ships or high level aircraft. Not all dual-purpose guns have high elevation, the determining factor was whether or not the mounting was provided with an anti-aircraft fire control system and a method for setting the time fuze in the A. A. warhead, fired by the gun. Starting with the Tribal class, the Royal Navy introduced a series of classes that had dual-purpose guns. XIX and later mountings limited to 40,50 or 55 degrees elevation, however, the guns were controlled by an A. A. fire control system, fire control and no on-mount fuze setters. Admiral Sir Philip Vian describes the use of 4, there was too little sea-room for full freedom of manoeuvre, and the aircrafts approach was screened by the rock walls. Junkers attacks persisted to the end, but the fire of the destroyers, not a ship received a direct hit, though some were damaged by the splinters from near misses. Dual-purpose guns, often abbreviated to DP guns, were designed as a secondary armament for large surface ships such as cruisers. Most DP mounted guns have calibers in the range from three to five inches, in British service the term HA/LA for High Angle/Low Angle was used

3"/50 caliber gun
–
For Army 3-inch gun see 3-inch M1918 gun The 3″/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U. S. Navy and U. S. Coast Guard from 1890 through the 1990s on a variety of combatant and transport ship classes. The US Navys first 3″/50 caliber gun was a model with a projectile velocity of 2,100 feet per second. Low-angle mountings for this gun had a range of 7000 yards at the elevation of 15 degrees. The gun entered service around 1900 with the Bainbridge-class destroyers, and was fitted to Connecticut-class battleships. By World War II these guns were only on a few Coast Guard cutters. These guns fired the same 2,700 feet per second used by the following dual-purpose Marks. These were built-up guns with a tube, partial-length jacket, hoop, dual-purpose 3″/50 caliber guns first entered service in 1915 as a refit to USS Texas, and were subsequently mounted on many types of ships as the need for anti-aircraft protection was recognized. They also replaced the original low-angle 4/50 caliber guns on flush-deck Wickes and these dual-purpose guns were quick-firing, meaning that they used fixed ammunition, with powder case and projectile permanently attached, and handled as a single unit weighing 34 pounds. Maximum range was 14,600 yards at 45 degrees elevation, useful life expectancy was 4300 effective full charges per barrel. The 3/50 caliber gun Marks 17 and 18 was first used as a deck gun on R-class submarines launched in 1918-1919. At the time it was an improvement on the earlier 3/23 caliber gun, after using larger guns on many other submarines, the 3/50 caliber gun Mark 21 was specified as the standard deck gun on the Porpoise- through Gato-class submarines launched in 1935-1942. The small gun was chosen to remove the temptation to engage enemy vessels on the surface. The gun was mounted aft of the conning tower to reduce submerged drag. Wartime experience showed that larger guns were needed and this need was initially met by transferring 4/50 caliber guns from S-class submarines as they were shifted from combat to training roles from late 1942. Later, the 5/25 caliber gun, initially removed from battleships sunk or damaged in the attack on Pearl Harbor and later manufactured in a submarine version, post-war experimentation with an extended range variant was abandoned as shipboard surface-to-air missiles were developed. The United States Navy considered contemporary 5/38 caliber guns and 5″/54 caliber guns more effective against surface targets, the 3″/50 caliber gun was a semiautomatic anti-aircraft weapon with a power driven automatic loader. These monobloc 3″ guns were fitted to both single and twin mountings, the single was to be exchanged for a twin 40 mm antiaircraft gun mount and the twin for a quadruple 40 mm mount

Bofors 40 mm gun
–
The Bofors 40 mm gun, often referred to simply as the Bofors gun, is an anti-aircraft/multi-purpose autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, a small number of these weapons remain in service to this day, and saw action as late as the Gulf War. In the post-war era the original design was not suitable for action against jet powered aircraft, so Bofors introduced a new model of more power. In spite of sharing almost nothing with the design other than the calibre and the distinctive conical flash hider. Although not as popular as the original L/60 model, the L/70 remains in service to this day, especially as a weapon for light armored vehicles. Bofors itself has been part of BAE Systems AB since March 2005, the Swedish Navy purchased a number of 2 pounder Pom-Poms from Vickers as anti-aircraft guns in 1922. The Navy approached Bofors about the development of a capable replacement. Bofors signed a contract in late 1928, Bofors produced a gun that was a smaller version of a 57 mm semi-automatic gun developed as an anti-torpedo boat weapon in the late 19th century by Finspong. Their first test gun was a re-barreled Nordenfelt version of the Finspong gun, testing of this gun in 1929 demonstrated that a problem existed feeding the weapon in order to maintain a reasonable rate of fire. A mechanism that was enough to handle the stresses of moving the large round was too heavy to move quickly enough to fire rapidly. One attempt to solve this problem used zinc shell cases that burned up when fired and this proved to leave heavy zinc deposits in the barrel, and had to be abandoned. This seemed to be the solution they needed, improving firing rates to a level. During this period Krupp purchased a share of Bofors. Krupp engineers started the process of updating the Bofors factories to use equipment and metallurgy. The prototype was completed and fired in November 1931, and by the middle of the month it was firing strings of two and three rounds. Changes to the mechanism were all that remained, and by the end of the year it was operating at 130 rounds per minute. Continued development was needed to turn it into a suitable for production. Since acceptance trials had been passed the year before, this known as the 40 mm akan M/32

Anti-aircraft warfare
–
Anti-aircraft warfare or counter-air defence is defined by NATO as all measures designed to nullify or reduce the effectiveness of hostile air action. They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and it may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be homeland defence, NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight, a surface-based air defence capability can also be deployed offensively to deny the use of airspace to an opponent. Until the 1950s, guns firing ballistic munitions ranging from 20 mm to 150 mm were the weapons, guided missiles then became dominant. The term air defence was probably first used by Britain when Air Defence of Great Britain was created as a Royal Air Force command in 1925. However, arrangements in the UK were also called anti-aircraft, abbreviated as AA, after the First World War it was sometimes prefixed by Light or Heavy to classify a type of gun or unit. Nicknames for anti-aircraft guns include AA, AAA or triple-A, an abbreviation of anti-aircraft artillery, ack-ack, NATO defines anti-aircraft warfare as measures taken to defend a maritime force against attacks by airborne weapons launched from aircraft, ships, submarines and land-based sites. In some armies the term All-Arms Air Defence is used for air defence by nonspecialist troops, other terms from the late 20th century include GBAD with related terms SHORAD and MANPADS. Anti-aircraft missiles are variously called surface-to-air missile, abbreviated and pronounced SAM, non-English terms for air defence include the German FlaK, whence English flak, and the Russian term Protivovozdushnaya oborona, a literal translation of anti-air defence, abbreviated as PVO. In Russian the AA systems are called zenitnye systems, in French, air defence is called DCA. The maximum distance at which a gun or missile can engage an aircraft is an important figure, however, many different definitions are used but unless the same definition is used, performance of different guns or missiles cannot be compared. For AA guns only the part of the trajectory can be usefully used. By the late 1930s the British definition was that height at which an approaching target at 400 mph can be engaged for 20 seconds before the gun reaches 70 degrees elevation. However, effective ceiling for heavy AA guns was affected by nonballistic factors, The maximum running time of the fuse, the capability of fire control instruments to determine target height at long range. The essence of air defence is to detect aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space, Air defence evolution covered the areas of sensors and technical fire control, weapons, and command and control. At the start of the 20th century these were very primitive or non-existent

Oerlikon 20 mm cannon
–
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German 20 mm Becker design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II, and many still in use today. During World War I, the German Reinhold Becker developed a 20 mm caliber cannon and this used a 20x70 RB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a scale as an aircraft gun on Luftstreitkräfte warplanes. Because the Treaty of Versailles banned further production of weapons in Germany. SEMAG continued development of the weapon, and in 1924 had produced the SEMAG L, the Oerlikon firm, named after the Zürich suburb where it was based, then acquired all rights to the weapon, plus the manufacturing equipment and the employees of SEMAG. In 1927 the Oerlikon S was added to the product line. This fired a larger cartridge to achieve a muzzle velocity of 830 m/s, at the cost of increased weight. The purpose of development was to improve the performance of the gun as an anti-tank and anti-aircraft weapon. An improved version known as the 1S followed in 1930, three sizes of gun with their different ammunition and barrel length, but very similar mechanisms, continued to be developed in parallel. In 1930 Oerlikon reconsidered the application of its gun in aircraft and introduced the AF and AL, designed to be used in flexible mounts, the 15-round box magazine used by earlier versions of the gun was replaced by drum magazine holding 15 or 30 rounds. In 1935 it made an important step by introducing a series of guns designed to be mounted in or on the wings of fighter aircraft, designated with FF for Flügelfest meaning wing-mounted, these weapons were again available in the three sizes, with designations FF, FFL and FFS. The FF fired a larger cartridge than the AF, 20x72RB. The FF weighed 24 kg and achieved a velocity of 550 to 600 m/s with a rate of fire of 520 rpm. The FFL of 30 kg fired a projectile at a velocity of 675 m/s with a rate of fire of 500 rpm. And the FFS, which weighed 39 kg, delivered a high velocity of 830 m/s at a rate of fire of 470 rpm. Apart from changes to the design of the guns for wing-mounting and remote control, for the FF series drum sizes of 45,60,75 and 100 rounds were available, but most users chose the 60-round drum. The 1930s were a period of global re-armament, and a number of foreign firms took licenses for the Oerlikon family of aircraft cannon

US 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. The U. S. Navy is the largest, most capable navy in the world, the U. S. Navy has the worlds largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 323,792 personnel on duty and 108,515 in the Navy Reserve. It has 274 deployable combat vessels and more than 3,700 operational aircraft as of October 2016, the U. S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. It played a role in the American Civil War by blockading the Confederacy. It played the role in the World War II defeat of Imperial Japan. The 21st century U. S. Navy maintains a global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean. The Navy is administratively managed by the Department of the Navy, the Department of the Navy is itself a division of the Department of Defense, which is headed by the Secretary of Defense. The Chief of Naval Operations is an admiral and the senior naval officer of the Department of the Navy. The CNO may not be the highest ranking officer in the armed forces if the Chairman or the Vice Chairman of the Joint Chiefs of Staff. The mission of the Navy is to maintain, train and equip combat-ready Naval forces capable of winning wars, deterring aggression, the United States Navy is a seaborne branch of the military of the United States. The Navys three primary areas of responsibility, The preparation of naval forces necessary for the prosecution of war. The development of aircraft, weapons, tactics, technique, organization, U. S. Navy training manuals state that the mission of the U. S. Armed Forces is to prepare and conduct prompt and sustained combat operations in support of the national interest, as part of that establishment, the U. S. Navys functions comprise sea control, power projection and nuclear deterrence, in addition to sealift duties. It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, the Navy was rooted in the colonial seafaring tradition, which produced a large community of sailors, captains, and shipbuilders. In the early stages of the American Revolutionary War, Massachusetts had its own Massachusetts Naval Militia, the establishment of a national navy was an issue of debate among the members of the Second Continental Congress. Supporters argued that a navy would protect shipping, defend the coast, detractors countered that challenging the British Royal Navy, then the worlds 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

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

Northern hemisphere
–
The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined as being in the celestial hemisphere relative to the invariable plane of the solar system as Earths North pole. Due to the Earths axial tilt, winter in the Northern Hemisphere lasts from the December solstice to the March Equinox, the dates vary each year due to the difference between the calendar year and the astronomical year. Its surface is 60. 7% water, compared with 80. 9% water in the case of the Southern Hemisphere, the Arctic is the region north of the Arctic Circle. Its climate is characterized by cold winters and cool summers, precipitation mostly comes in the form of snow. The Arctic experiences some days in summer when the Sun never sets, the duration of these phases varies from one day for locations right on the Arctic Circle to several months near the North Pole, which is the middle of the Northern Hemisphere. Between the Arctic Circle and the Tropic of Cancer lies the Northern Temperate Zone, the changes in these regions between summer and winter are generally mild, rather than extreme hot or cold. However, a temperate climate can have very unpredictable weather, tropical regions are generally hot all year round and tend to experience a rainy season during the summer months, and a dry season during the winter months. In the Northern Hemisphere, objects moving across or above the surface of the Earth tend to turn to the right because of the coriolis effect, as a result, large-scale horizontal flows of air or water tend to form clockwise-turning gyres. These are best seen in circulation patterns in the North Atlantic. For the same reason, flows of air down toward the surface of the Earth tend to spread across the surface in a clockwise pattern. Thus, clockwise air circulation is characteristic of high pressure weather cells in the Northern Hemisphere, conversely, air rising from the northern surface of the Earth tends to draw air toward it in a counterclockwise pattern. Hurricanes and tropical storms spin counter-clockwise in the Northern Hemisphere, the shadow of a sundial moves clockwise in the Northern Hemisphere. When viewed from the Northern Hemisphere, the Moon appears inverted compared to a view from the Southern Hemisphere, the North Pole faces away from the galactic center of the Milky Way. The Northern Hemisphere is home to approximately 6.57 billion people which is around 90% of the total human population of 7.3 billion people

Constellation
–
A constellation is formally defined as a region of the celestial sphere, with boundaries laid down by the International Astronomical Union. The constellation areas mostly had their origins in Western-traditional patterns of stars from which the constellations take their names, in 1922, the International Astronomical Union officially recognized the 88 modern constellations, which cover the entire sky. They began as the 48 classical Greek constellations laid down by Ptolemy in the Almagest, Constellations in the far southern sky are late 16th- and mid 18th-century constructions. 12 of the 88 constellations compose the zodiac signs, though the positions of the constellations only loosely match the dates assigned to them in astrology. The term constellation can refer to the stars within the boundaries of that constellation. Notable groupings of stars that do not form a constellation are called asterisms, when astronomers say something is “in” a given constellation they mean it is within those official boundaries. Any given point in a coordinate system can unambiguously be assigned to a single constellation. Many astronomical naming systems give the constellation in which an object is found along with a designation in order to convey a rough idea in which part of the sky it is located. For example, the Flamsteed designation for bright stars consists of a number, the word constellation seems to come from the Late Latin term cōnstellātiō, which can be translated as set of stars, and came into use in English during the 14th century. It also denotes 88 named groups of stars in the shape of stellar-patterns, the Ancient Greek word for constellation was ἄστρον. Colloquial usage does not draw a distinction between constellation in the sense of an asterism and constellation in the sense of an area surrounding an asterism. The modern system of constellations used in astronomy employs the latter concept, the term circumpolar constellation is used for any constellation that, from a particular latitude on Earth, never sets below the horizon. From the North Pole or South Pole, all constellations south or north of the equator are circumpolar constellations. In the equatorial or temperate latitudes, the term equatorial constellation has sometimes been used for constellations that lie to the opposite the circumpolar constellations. They generally include all constellations that intersect the celestial equator or part of the zodiac, usually the only thing the stars in a constellation have in common is that they appear near each other in the sky when viewed from the Earth. In galactic space, the stars of a constellation usually lie at a variety of distances, since stars also travel on their own orbits through the Milky Way, the star patterns of the constellations change slowly over time. After tens to hundreds of thousands of years, their familiar outlines will become unrecognisable, the terms chosen for the constellation themselves, together with the appearance of a constellation, may reveal where and when its constellation makers lived. The earliest direct evidence for the constellations comes from inscribed stones and it seems that the bulk of the Mesopotamian constellations were created within a relatively short interval from around 1300 to 1000 BC

Lieutenant Commander (United States)
–
Lieutenant commanders rank above lieutenants and below commanders, and rank is equivalent to a major in the other United States Army, United States Air Force, and United States Marine Corps. Promotion to lieutenant commander in the U. S. Navy is governed by United States Department of Defense policies derived from the Defense Officer Personnel Management Act of 1980. While lieutenant commander is the U. S. Navys first commissioned officer to be selected by board, they are considered to be junior officers due to their origin as lieutenant. This can be seen by the fact that lieutenant commanders do not wear the oak-leaf gold embellishment on their combination covers and this is in contrast to other branches, where majors wear the appropriate covers of field-grade officers. The United States Coast Guard used their own system until World War I. In 1916, discontent grew among Coast Guard Captains By law, the Appropriations Act of 1918, the Coast Guard adopted the Navy rank structure to prevent against disagreements over seniority. There are two insignia used by lieutenant commanders, in all dress uniforms, they wear sleeve braid or shoulder boards bearing a single gold quarter-inch stripe between two gold half-inch strips. Above or inboard of the stripes, they wear their specialty insignia, military unit Comparative military ranks U. S. Navy officer rank insignia

San Francisco, California
–
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

Solomon Islands
–
The countrys capital, Honiara, is located on the island of Guadalcanal. The islands have been inhabited for thousands of years, in 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them, naming them the Islas Salomón. Britain defined its area of interest in the Solomon Islands archipelago in June 1893, during World War II, the Solomon Islands campaign saw fierce fighting between the United States and the Empire of Japan, such as in the Battle of Guadalcanal. The official name of the then British overseas territory was changed from the British Solomon Islands Protectorate to Solomon Islands in 1975, self-government was achieved in 1976, independence was obtained two years later. Today, Solomon Islands is a monarchy with the Queen of Solomon Islands, currently Queen Elizabeth II. Manasseh Sogavare is the current prime minister, in 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit the Solomon Islands archipelago, naming it Islas Salomón after the wealthy biblical King Solomon. It is said that they were given name in the mistaken assumption that they contained great riches. During most of the period of British rule the territory was named the British Solomon Islands Protectorate. On 22 June 1975 the territory was renamed Solomon Islands, when Solomon Islands became independent in 1978 they retained the name. The definite article, the, is not part of the official name but is sometimes used. It is believed that Papuan-speaking settlers began to arrive around 30,000 BC, austronesian speakers arrived c.4000 BC also bringing cultural elements such as the outrigger canoe. Between 1200 and 800 BC the ancestors of the Polynesians, the Lapita people, the first European to visit the islands was the Spanish navigator Álvaro de Mendaña de Neira, coming from Peru in 1568. The people of Solomon Islands were notorious for headhunting and cannibalism before the arrival of the Europeans, missionaries began visiting the Solomons in the mid-19th century. They made little progress at first, because blackbirding led to a series of reprisals, the evils of the labour trade prompted the United Kingdom to declare a protectorate over the southern Solomons in June 1893. Traditional trade and social intercourse between the western Solomon Islands of Mono and Alu and the societies in the south of Bougainville, however. Missionaries settled in the Solomons under the protectorate, converting most of the population to Christianity, in the early 20th century several British and Australian firms began large-scale coconut planting. Economic growth was slow, however, and the islanders benefited little, journalist Joe Melvin visited in 1892, as part of his undercover investigation into blackbirding. In 1908 the islands were visited by Jack London, who was cruising the Pacific on his boat, with the outbreak of the Second World War most planters and traders were evacuated to Australia and most cultivation ceased

Auckland
–
Auckland is a city in the North Island of New Zealand. It is the most populous area in the country. Auckland has a population of 1,495,000, which constitutes 32 percent of New Zealands population, a diverse and multicultural city, Auckland is home to the largest Polynesian population in the world. It has also been called Ākarana, the Māori pronunciation of Auckland, the Auckland urban area ranges to Waiwera in the north, Kumeu in the northwest, and Runciman in the south. It is not contiguous, the section from Waiwera to Whangaparāoa Peninsula is separate from its nearest neighbouring suburb of Long Bay, the surrounding hills are covered in rainforest and the landscape is dotted with dozens of dormant volcanic cones. The central part of the area occupies a narrow isthmus between the Manukau Harbour on the Tasman Sea and the Waitemata Harbour on the Pacific Ocean. It is one of the few cities in the world to have harbours on two major bodies of water. The isthmus on which Auckland resides was first settled around 1350 and was valued for its rich, Māori population in the area is estimated to have peaked at 20,000 before the arrival of Europeans. After a British colony was established in 1840, the new Governor of New Zealand, William Hobson and he named the area Auckland for George Eden, Earl of Auckland, British First Lord of the Admiralty. It was replaced as the capital in 1865, but immigration to the new city stayed strong, today, Aucklands Central Business District is the major financial centre of New Zealand. Auckland is classified as a Beta World City because of its importance in finance, commerce, media, entertainment, arts, education and tourism. Aucklands landmarks such as the Auckland Art Gallery Toi o Tāmaki, the Harbour Bridge, the Sky Tower, the isthmus was settled by Māori around 1350, and was valued for its rich and fertile land. Many pā were created, mainly on the volcanic peaks, Māori population in the area is estimated to have been about 20,000 people before the arrival of Europeans. As a result, the region had relatively low numbers of Māori when European settlement of New Zealand began, there is, however, nothing to suggest that this was the result of a deliberate European policy. Auckland was officially declared New Zealands capital in 1841 and the transfer of the administration from Russell in the Bay of Islands was completed in 1842. However, even in 1840 Port Nicholson was seen as a choice for an administrative capital because of its proximity to the South Island. After losing its status as capital, Auckland remained the city of the Auckland Province until the provincial system was abolished in 1876. Each of the four settlements had about 800 settlers, the men being fully armed in case of emergency but spent nearly all their time breaking in the land and establishing roads

Guadalcanal
–
Guadalcanal is the principal island in Guadalcanal Province of the nation of Solomon Islands in the south-western Pacific, northeast of Australia. Its European discovery was under the Spanish expedition of Álvaro de Mendaña in 1568, the name comes from Guadalcanal, a village in the province of Seville, in Andalusia, Spain, birthplace of Pedro de Ortega Valencia, a member of Mendañas expedition. During 1942–43 it was the scene of the Guadalcanal Campaign, at the end of the war, Honiara, on the north coast of Guadalcanal, became the new capital of the British Solomon Islands Protectorate. Guadalcanal is mainly covered in tropical rainforest and it has a mountainous interior. A Spanish expedition from Peru under the command of Álvaro de Mendaña de Neira discovered the island in the year 1568, Mendañas subordinate, Pedro de Ortega Valencia, named the island after his home town Guadalcanal in Andalusia, Spain. The name comes from the Arabic Wādī l-Khānāt, which means Valley of the Stalls or River of Stalls, in 1932, the British confirmed the name Guadalcanal in line with the town in Andalusia, Spain. In the months following the attack on Pearl Harbor in December 1941, the Japanese drove the Americans out of the Philippines, the British out of British Malaya, the Japanese reached Guadalcanal in May 1942. When an American reconnaissance mission spotted construction of a Japanese airfield at Lunga Point on the north coast of Guadalcanal, Guadalcanal became a major turning point in the war as it stopped Japanese expansion. After six months of fighting, the Japanese ceased contesting the control of the island and they finally evacuated the island at Cape Esperance on the north west coast in February 1943. Immediately after landing on the island, the US Navy Seabees began finishing the airfield begun by the Japanese and it was then named Henderson Field after a Marine aviator killed in combat during the Battle of Midway. Aircraft operating from Henderson Field during the campaign were a hodgepodge of Marine, Army, Navy and they defended the airfield and threatened any Japanese ships that ventured into the vicinity during daylight hours. However, at night, Japanese naval forces were able to shell the airfield and deliver troops with supplies, the Japanese used fast ships to make these runs, and this became known as the Tokyo Express. So many ships from both sides were sunk in the engagements in and around the Solomon Island chain that the nearby waters were referred to as Ironbottom Sound. The Battle of Cape Esperance was fought on 11 October 1942 off the northwest coast of Guadalcanal. In the battle, United States Navy ships intercepted and defeated a Japanese formation of ships on their way down the Slot to reinforce and resupply troops on the island, American authorities declared Guadalcanal secure on 9 February 1943. Two US Navy ships have been named for the battle, USS Guadalcanal, USS Guadalcanal, an amphibious assault ship. Munro provided a shield and covering fire, and helped evacuate 500 besieged Marines from a beach at Point Cruz, during the Battle for Guadalcanal, the Medal of Honor was also awarded to John Basilone who later died on Iwo Jima. Immediately after the Second World War, the capital of the British Solomon Islands Protectorate was moved to Honiara on Guadalcanal from its previous location at Tulagi in the Florida Islands

Panama Canal Zone
–
The Panama Canal Zone was an unincorporated territory of the United States from 1903 to 1979, centered on the Panama Canal and surrounded by the Republic of Panama. Its border spanned two of Panamas provinces, when reservoirs were created to assure a steady supply of water for the locks, those lakes were included within the Zone. On February 26,1904, the Isthmian Canal Convention was proclaimed, from 1903 to 1979 the territory was controlled by the United States, which had built the canal and financed its construction. Proposals for a canal across the Isthmus of Panama date back to 1529, Álvaro de Saavedra Cerón, a lieutenant of conquistador Vasco Núñez de Balboa, suggested four possible routes, one of which closely tracks the present-day canal. Saavedra believed that such a canal would make it easier for European vessels to reach Asia, although King Charles I was enthusiastic and ordered preliminary works started, his officials in Panama soon realized that such an undertaking was beyond the capabilities of 16th-century technology. One official wrote to Charles, I pledge to Your Majesty that there is not a prince in the world with the power to accomplish this, the Spanish instead built a road across the isthmus. Although additional canal building proposals were made throughout the 16th and 17th centuries, the late 18th and early 19th centuries saw a number of canals built. The success of the Erie Canal in the United States and the collapse of the Spanish Empire in Latin America led to a surge of American interest in building an interoceanic canal. Beginning in 1826, US officials began negotiations with New Granada, jealous of their newly obtained independence and fearing that they would be dominated by an American presence, New Granadan officials declined American offers. The new nation was politically unstable, and Panama rebelled several times during the 19th century and his agreement was repudiated by the Jackson administration, which wanted rights to build a canal. In 1846, the new US envoy to Bogotá, Benjamin Bidlack, was surprised when, soon after his arrival, the resulting Mallarino–Bidlack Treaty allowed the United States to intervene militarily to ensure that the interoceanic road would not be disrupted. The treaty led the U. S. government to contract for service to Panama from ports on both coasts. When the California Gold Rush began in 1848, traffic through Panama greatly increased and this first transcontinental railroad opened in 1850. There were riots in Panama CIty in 1856, several Americans were killed, US warships landed Marines, who occupied the railroad station and kept the railroad service from being interrupted by the unrest. The demand was dropped in the face of resistance by New Granadan officials, through the remainder of the 19th century, the United States landed troops several times to preserve the railway connection. At the same time, it pursued a canal treaty with Colombia, one treaty, signed in 1868, was rejected by the Colombian Senate, which hoped for better terms from the incoming Grant administration. Under this treaty, the canal would have been in the middle of a 20-mile zone, under American management but Colombian sovereignty, the Grant administration did little to pursue a treaty, and in 1878, the concession to build the canal fell to a French firm. The French efforts eventually failed, but with Panama apparently unavailable, the Spanish–American War of 1898 added new life to the canal debate

Norfolk, Virginia
–
Norfolk is an independent city in the Commonwealth of Virginia, United States. At the 2010 census, the population was 242,803, in 2015, Norfolk is located at the core of the Hampton Roads metropolitan area, named for the large natural harbor of the same name located at the mouth of Chesapeake Bay. It is one of nine cities and seven counties that constitute the Hampton Roads metro area, officially known as the Virginia Beach-Norfolk-Newport News, the city is bordered to the west by the Elizabeth River and to the north by the Chesapeake Bay. It also shares borders with the independent cities of Chesapeake to its south. Norfolk is one of the oldest cities in Hampton Roads, and is considered to be the historic, urban, financial, the city has a long history as a strategic military and transportation point. The largest Navy base in the world, Naval Station Norfolk, is located in Norfolk along with one of NATOs two Strategic Command headquarters. As the city is bordered by multiple bodies of water, Norfolk has many miles of riverfront and bayfront property, including beaches on the Chesapeake Bay. It is linked to its neighbors by a network of Interstate highways, bridges, tunnels. In 1619, the Governor of the Virginia Colony, Sir George Yeardley incorporated four jurisdictions, termed citties and these formed the basis for colonial representative government in the newly minted House of Burgesses. What would become Norfolk was put under the Elizabeth Cittie incorporation, in 1634 King Charles I reorganized the colony into a system of shires. The former Elizabeth Cittie became Elizabeth City Shire, after persuading 105 people to settle in the colony, Adam Thoroughgood was granted a large land holding, through the head rights system, along the Lynnhaven River in 1636. When the South Hampton Roads portion of the shire was separated, one year later, it was split into two counties, Upper Norfolk and Lower Norfolk, chiefly on Thoroughgoods recommendation. This area of Virginia became known as the place of entrepreneurs, the House of Burgesses established the Towne of Lower Norfolk County in 1680. In 1691, a final county subdivision took place when Lower Norfolk County split to form Norfolk County, in 1730, a tobacco inspection site was located here. By 1775, Norfolk developed into what contemporary observers argued was the most prosperous city in Virginia and it was an important port for exporting goods to the British Isles and beyond. In part because of its merchants numerous trading ties with other parts of the British Empire, after fleeing the colonial capital of Williamsburg, Lord Dunmore, the Royal Governor of Virginia, tried to reestablish control of the colony from Norfolk. Dunmore secured small victories at Norfolk but was forced into exile by the American rebels and his departure brought an end to more than 168 years of British colonial rule in Virginia. On New Years Day,1776, Lord Dunmores fleet of three ships shelled the city of Norfolk for more than eight hours, the damage from the shells and fires started by the British and spread by the patriots destroyed over 800 buildings, almost two-thirds of the city

Dictionary of American Naval Fighting Ships
–
The Dictionary of American Naval Fighting Ships is the official reference work for the basic facts about ships used by the United States Navy. When the writing project was developed the parameters for this series were designed to cover only commissioned US Navy ships with assigned names, if the ship was not assigned a name it was not included in the histories written for the series. In addition to the entries, DANFS and the online links have been expanded to include appendices on small craft, histories of Confederate Navy ships. DANFS was published in print by the Naval Historical Center as bound volumes, ordered by ship name. Several volumes subsequently went out of print, in 1991 a revised Volume I Part A, covering only ship names beginning with A, was released. Work continues on revisions of the remaining volumes, volunteers at the Hazegray website undertook to transcribe the DANFS and make it available on the World Wide Web. The project goal is a transcription of the DANFS, with changes limited to correcting typographical errors. In 2008 the NHC was re-designated as the Naval History and Heritage Command and it has developed an online version of DANFS through a combination of optical character recognition and hand transcription. The NHHC is slowly updating its online DANFS to correct errors, the NHHC has begun a related project to place Ship History and Command Operations Reports online at their DANFS site. As the DANFS is a work of the U. S. government, its content is in the domain. Many websites organized by former and active members of U. S. Navy vessels include a copy of their ships DANFS entries. The Dictionary limits itself largely to basic descriptions and brief operational notes, and includes almost no analysis or historical context

United States Department of the Navy
–
The Secretary of the Navy is appointed by the President with the advice and consent of the Senate. They supervise their military services of the Department of the Navy. They are assisted by a Vice Chief of Naval Operations and an Assistant Commandant of the Marine Corps. Unlike its U. S. Army and U. S. Air Force counterparts, the Department of the Navy consists of all elements of the United States Navy and the United States Marine Corps. According to Navy Regulations Section 0204-2, the term Navy Department refers only to the offices at the seat of government. The bill passed in the House on 17 May 2007, but encountered opposition among members of the DoD civilian leadership and among senior Navy admirals, in the Senate, the provision was replaced in S.

Naval History and Heritage Command
–
When the British invaded Washington in 1814 this collection, containing the finest works on naval history from America and abroad, was rushed to safety outside the Federal City. Thereafter the library had many locations, including a specially designed space in the State, War and he also began to collect and preserve naval records, particularly those of the American Civil War. Congress initially recognized his efforts by authorizing funds for staff and combining the library and records sections into the Office of Library. In 1915 the appropriations for publications, the library, and naval war records were combined, once America entered World War I, emphasis shifted to gathering documents on current naval operations.

Public domain
–
The term public domain has two senses of meaning. Anything published is out in the domain in the sense that it is available to the public. Once published, news and information in books is in the public domain, in the sense of intellectual property, works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, or are inapplicable. Examples for works not covered by copyright which are therefore in the domain, are the formulae of Newtonian physics, cooking recipes. Examples for works actively dedicated into public domain by their authors are reference implementations of algorithms, NIHs ImageJ. The term is not normally applied to situations where the creator of a work retains residual rights, as rights are country-based and vary, a work may be subject to rights in one country and be in the public domain in another. Some rights depend on registrations on a basis, and the absence of registration in a particular country, if required. Although the term public domain did not come into use until the mid-18th century, the Romans had a large proprietary rights system where they defined many things that cannot be privately owned as res nullius, res communes, res publicae and res universitatis. The term res nullius was defined as not yet appropriated. The term res communes was defined as things that could be enjoyed by mankind, such as air, sunlight. The term res publicae referred to things that were shared by all citizens, when the first early copyright law was first established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by British and French jurists in the eighteenth century, instead of public domain they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law. The phrase fall in the domain can be traced to mid-nineteenth century France to describe the end of copyright term. In this historical context Paul Torremans describes copyright as a coral reef of private right jutting up from the ocean of the public domain. Because copyright law is different from country to country, Pamela Samuelson has described the public domain as being different sizes at different times in different countries. According to James Boyle this definition underlines common usage of the public domain and equates the public domain to public property. However, the usage of the public domain can be more granular. Such a definition regards work in copyright as private property subject to fair use rights, the materials that compose our cultural heritage must be free for all living to use no less than matter necessary for biological survival
