United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Red Oak, Iowa
–
Red Oak is a city in and the county seat of Montgomery County, Iowa, United States, located along the East Nishnabotna River. The population was 5,742 in the 2010 census, a decline from the 6,197 population in the 2000 census, Red Oak derives its name from Red Oak Creek which flows through the community and was noted for the red oaks on its banks. The first settlers arrived there in the 1850s and that courthouse remained in place until the current Montgomery County Courthouse was built in 1891. It is on the National Register of Historic Places, in 1869 the community was officially founded when the Chicago, Burlington and Quincy Railroad arrived. The community was named Red Oak Junction by the railroad on March 20,1876, the junction was a line off the main Chicago to Council Bluffs, Iowa line that went to Nebraska City, Nebraska and on to Lincoln, Nebraska. The Junction name was dropped in 1901 although the community continues to celebrate its history each summer in Junction Days, in 1903 a new depot was opened by the railroad. It today serves as a museum celebrating the significant military heritage and its disproportionate number of casualties in various wars. The depot is one of nine places in Montgomery County on the National Register of Historic Places listings in Montgomery County, Iowa. Darwin R. Merritt, born in Red Oak on April 12,1872, graduated third in his class from the United States Naval Academy in Annapolis, Maryland on July 1,1897. On February 15,1898, he perished in the explosion that sank the USS Maine in the harbor of Havana and his body was later recovered and interred in Evergreen Cemetery in Red Oak. The community has had a number of casualties in the Civil War. In the American Civil War, the area provided more Union troops per capita than any other in the state, company M had 160 casualties among its 250 members,52 men were killed in action. Early World War II battles claimed a number of soldiers from Red Oak. In the Battle of the Kasserine Pass in February 1943, forty-five soldiers from Red Oak alone were captured or killed, at the time more than 100 telegrams arrived in Red Oak saying that its soldiers were missing in action. In recognition of Red Oaks extraordinary sacrifice, the name was given to a victory ship. The SS Red Oak Victory has become a museum in the shipyard where it was built, in Richmond. The old Burlington Northern depot has been transformed into a museum telling this history, the Red Oak School District was established in 1870, while Webster Eaton first published the Red Oak Express newspaper in 1868. Red Oak is located at 41°0′42″N 95°13′38″W, according to the United States Census Bureau, the city has a total area of 4.01 square miles, of which,3.95 square miles is land and 0.06 square miles is water

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

IMO number
–
The International Maritime Organization number is a unique reference for ships and for registered ship owners and management companies. IMO numbers were introduced under the SOLAS Convention to improve safety and security. For ships, the IMO number remains linked to the hull for its lifetime, regardless of a change in name, flag, or owner. The ship number consists of the three letters IMO followed by a unique number assigned to sea-going merchant ships under the International Convention for the Safety of Life at Sea. In 1987 the IMO adopted Resolution A, in the SOLAS Convention cargo ships means ships which are not passenger ships. Passenger ships should carry the marking on a horizontal surface visible from the air. When introduced, the IMO adopted the existing unique ship numbers applied to ships listed by Lloyds Register since 1963, IMO ship identification numbers are assigned by IHS Fairplay. For new vessels the IMO number is assigned to a hull during construction, the IMO ship identification number is made of the three letters IMO followed by the seven-digit number. This consists of a six-digit sequential unique number followed by a check digit, the integrity of an IMO number can be verified using its check digit. This is done by multiplying each of the first six digits by a factor of 2 to 7 corresponding to their position from right to left, the rightmost digit of this sum is the check digit. For example, for IMO9074729, + + + + + =139, in May 2005, IMO adopted a new SOLAS regulation XI-1/3-1 on the mandatory company and registered owner identification number scheme, with entry into force on 1 January 2009. Like the IMO ship number, the identification number is a seven-digit number with the prefix IMO

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

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

Water-tube 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

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.

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

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

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

National Register of Historic Places
–
The National Register of Historic Places is the United States federal governments official list of districts, sites, buildings, structures, and objects deemed worthy of preservation. The passage of the National Historic Preservation Act in 1966 established the National Register, of the more than one million properties on the National Register,80,000 are listed individually. The remainder are contributing resources within historic districts, each year approximately 30,000 properties are added to the National Register as part of districts or by individual listings. For most of its history the National Register has been administered by the National Park Service and its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, coordinate, identify, and protect historic sites in the United States. While National Register listings are mostly symbolic, their recognition of significance provides some financial incentive to owners of listed properties, protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places, the application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. Occasionally, historic sites outside the proper, but associated with the United States are also listed. Properties can be nominated in a variety of forms, including individual properties, historic districts, the Register categorizes general listings into one of five types of properties, district, site, structure, building, or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties, some properties are added automatically to the National Register when they become administered by the National Park Service. These include National Historic Landmarks, National Historic Sites, National Historical Parks, National Military Parks/Battlefields, National Memorials, on October 15,1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices. Initially, the National Register consisted of the National Historic Landmarks designated before the Registers creation, approval of the act, which was amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy. To administer the newly created National Register of Historic Places, the National Park Service of the U. S. Department of the Interior, hartzog, Jr. established an administrative division named the Office of Archeology and Historic Preservation. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law, ernest Connally was the Offices first director. Within OAHP new divisions were created to deal with the National Register, the first official Keeper of the Register was William J. Murtagh, an architectural historian. During the Registers earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small, understaffed, and underfunded. A few years later in 1979, the NPS history programs affiliated with both the U. S. National Parks system and the National Register were categorized formally into two Assistant Directorates. Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation, from 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs, jerry L. Rogers was selected to direct this newly merged associate directorate

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Victory ship
–
The Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. A total of 531 Victory ships were built, one of the first acts of the United States War Shipping Administration upon its formation in February 1942 was to commission the design of what came to be known as the Victory class. The design was an enhancement of the Liberty ship, which had successfully produced in extraordinary numbers. Victory ships were larger than Liberty ships,14 feet longer at 455 feet,6 feet wider at 62 ft. Displacement was up just under 1,000 tons, to 15,200, with a raised forecastle and a more sophisticated hull shape to help achieve the higher speed, they had a quite different appearance from Liberty ships. To make them vulnerable to U-boat attacks, Victory ships made 15 to 17 knots,4 to 6 knots faster than the Libertys. The extra speed was achieved through more modern, efficient engines, most used steam turbines, which had been in short supply earlier in the war and reserved for warships. All were oil-fired, but for a handful of Canadian vessels completed with both coal bunkers and oil tanks, another improvement was electrically powered auxiliary equipment, rather than steam-driven machinery. To prevent the hull fractures that a few Liberty ships developed and these were manned by United States Navy Armed Guard personnel. The VC2-S-AP5 Haskell-class attack transports were armed with the 5-inch stern gun, one quad 40 mm Bofors cannon, four dual 40 mm Bofors cannon, the Haskells were operated and crewed exclusively by U. S. Navy personnel. The Victory ship was noted for good proportion of cubic between holds for a ship of its day. A Victory ships cargo hold one, two and five hatches are a single rigged with a capacity of 70,400,76,700, and 69,500 bale cubic feet respectively. Victory ships hold three and four hatches are double rigged with a capacity of 136,100 and 100,300 bale cubic feet respectively. Victory ship have built in mast, booms and derrick cranes, the first vessel was SS United Victory launched at Oregon Shipbuilding Corporation on 12 January 1944 and completed on 28 February 1944, making her maiden voyage a month later. American vessels frequently had a name incorporating the word Victory, the British and Canadians used Fort and Park respectively. Although initial deliveries were slow—only 15 had been delivered by May 1944—by the end of the war 531 had been constructed, because the Atlantic battle had been won by the time that the first of the Victory ships appeared none were sunk by U-boats. Three were sunk by Japanese kamikaze attack in April of 1945, many Victory ships were converted to troopship to bring US soldiers home at the end of World War II as part of Operation Magic Carpet. A total of 97 Victory ships were converted to carry up to 1,600 soldiers

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

Museum ship
–
A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the number of museum ships that are still operational. Many, if not most, museum ships are also associated with a maritime museum, only a few survive, sometimes because of historical significance, but more often due to luck and circumstance. The restoration and maintenance of museum ships presents problems for historians who are asked for advice, for instance, the rigging of sailing ships has almost never survived, and so the rigging plan must be reconstructed from various sources. Studying the ships also allows historians to analyze how life on and operation of the ships took place, numerous scientific papers have been written on ship restoration and maintenance, and international conferences are held discussing the latest developments. Another consideration is the distinction between a museum ship, and a ship replica. As repairs accumulate over time, less and less of the ship is of the materials. Visitors without historical background are often unable to distinguish between a historical museum ship and a ship replica, which may serve solely as a tourist attraction. Typically the visitor enters via gangplank, wanders around on the deck, then goes below, usually using the original stairways, giving a sense of how the crew got around. The interior features restored but inactivated equipment, enhanced with mementos including old photographs, explanatory displays, pages from the logs, menus. Some add recorded sound effects, audio tours or video displays to enhance the experience, in some cases, the ships radio room has been brought back into use, with volunteers operating amateur radio equipment. Often, the callsign assigned is a variation on the identification of the ship. For example, the submarine USS Cobia, which had the call NBQV, is now on the air as NB9QV. The World War II submarine USS Pampanito, berthed at the San Francisco Maritime National Historical Park, had the wartime call NJVT and is now on the air as NJ6VT, in other cases, such as the USS Missouri, a distinctive call is used. This radio work not only helps restore part of the vessel, a number of the larger museum ships have begun to offer hosting for weddings, meetings, other events, and sleepovers, and on a few ships still seaworthy, cruises. In the United States, this includes the USS Constitutions annual turnaround, a place on the deck is by invitation or lottery only, and highly prized. Many consider the appeal of an interesting old vessel on the city waterfront strong enough that any port city should showcase one or more museum ships. This may even include building a ship at great expense

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

United States Merchant Marine
–
The United States Merchant Marine refers to either United States civilian mariners, or to U. S. civilian and federally owned merchant vessels. Merchant Marine officers may also be commissioned as officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the Naval Reserves. As of 31 December 2016, the United States merchant fleet had 175 privately owned, oceangoing, self-propelled vessels of 1,000 gross register tons, nearly 800 American-owned ships are flagged in other nations. In 2004, the government employed approximately 5% of all American water transportation workers. In the 19th and 20th centuries, various laws fundamentally changed the course of American merchant shipping and these laws put an end to common practices such as flogging and shanghaiing, and increased shipboard safety and living standards. The United States Merchant Marine is also governed by more than 25 international conventions to promote safety, the Court held that the Secretary of the Air Force abused its discretion in denying active military service recognition to American merchant seamen who participated in World War II. Captains, mates, and pilots supervise ship operations on domestic waterways, a captain is in overall command of a vessel, and supervises the work of other officers and crew. A captain has the ability to take the conn from a mate or pilot at any time he feels the need, on smaller vessels the captain may be a regular watch-stander, similar to a mate, directly controlling the vessels position. Captains directly communicate with the company or command, and are responsible for cargo, various logs, ships documents, credentials, efforts at controlling pollution. Mates direct a ships routine operation for the captain during work shifts, mates stand watch for specified periods, usually in three duty sections, with 4 hours on watch and 8 hours off. When on a watch, mates direct a bridge team by conning, directing courses through the helmsman. When more than one mate is necessary aboard a ship, they typically are designated chief mate or first mate, second mate, in addition to watch standers, mates directly supervise the ships crew, and are assigned other tasks. The chief mate is usually in charge of cargo, stability and the crew, the second mate in charge of navigation plans and updates. Harbor pilots guide ships in and out of confined waterways, such as harbors, harbor pilots are generally independent contractors who accompany vessels while they enter or leave port, and may pilot many ships in a single day. Ships engineers operate, maintain, and repair engines, boilers, generators, pumps, Merchant marine vessels usually have four engineering officers, a chief engineer and a first, second, and third assistant engineer. On many ships, Assistant Engineers stand periodic watches, overseeing the operation of engines. However, most modern ships sailing today utilize Unmanned Machinery Space automation technology, at night and during meals and breaks, the engine room is unmanned and machinery alarms are answered by the Duty Engineer

United States Navy
–
The United States Navy is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. 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

Korean War
–
The Korean War began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, China came to the aid of North Korea, and the Soviet Union gave some assistance. Korea was ruled by Japan from 1910 until the days of World War II. In August 1945, the Soviet Union declared war on Japan, as a result of an agreement with the United States, U. S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments, both governments claimed to be the legitimate government of all of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union, on that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83, Complaint of aggression upon the Republic of Korea and decided the formation, twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UNs military personnel. After the first two months of war, South Korean forces were on the point of defeat, forced back to the Pusan Perimeter, in September 1950, an amphibious UN counter-offensive was launched at Inchon, and cut off many North Korean troops. Those who escaped envelopment and capture were rapidly forced back north all the way to the border with China at the Yalu River, at this point, in October 1950, Chinese forces crossed the Yalu and entered the war. Chinese intervention triggered a retreat of UN forces which continued until mid-1951, after these reversals of fortune, which saw Seoul change hands four times, the last two years of fighting became a war of attrition, with the front line close to the 38th parallel. The war in the air, however, was never a stalemate, North Korea was subject to a massive bombing campaign. Jet fighters confronted each other in combat for the first time in history. The fighting ended on 27 July 1953, when an armistice was signed, the agreement created the Korean Demilitarized Zone to separate North and South Korea, and allowed the return of prisoners. However, no treaty has been signed, and the two Koreas are technically still at war. Periodic clashes, many of which are deadly, continue to the present, in the U. S. the war was initially described by President Harry S. Truman as a police action as it was an undeclared military action, conducted under the auspices of the United Nations. In South Korea, the war is referred to as 625 or the 6–2–5 Upheaval. In North Korea, the war is referred to as the Fatherland Liberation War or alternatively the Chosǒn War. In China, the war is called the War to Resist U. S

Vietnam War
–
It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The war is considered a Cold War-era proxy war. As the war continued, the actions of the Viet Cong decreased as the role. U. S. and South Vietnamese forces relied on air superiority and overwhelming firepower to conduct search and destroy operations, involving ground forces, artillery, in the course of the war, the U. S. conducted a large-scale strategic bombing campaign against North Vietnam. The North Vietnamese government and the Viet Cong were fighting to reunify Vietnam and they viewed the conflict as a colonial war and a continuation of the First Indochina War against forces from France and later on the United States. The U. S. government viewed its involvement in the war as a way to prevent a communist takeover of South Vietnam and this was part the domino theory of a wider containment policy, with the stated aim of stopping the spread of communism. Beginning in 1950, American military advisors arrived in what was then French Indochina, U. S. involvement escalated in the early 1960s, with troop levels tripling in 1961 and again in 1962. Regular U. S. combat units were deployed beginning in 1965, despite the Paris Peace Accord, which was signed by all parties in January 1973, the fighting continued. In the U. S. and the Western world, a large anti-Vietnam War movement developed as part of a larger counterculture, the war changed the dynamics between the Eastern and Western Blocs, and altered North–South relations. Direct U. S. military involvement ended on 15 August 1973, the capture of Saigon by the North Vietnamese Army in April 1975 marked the end of the war, and North and South Vietnam were reunified the following year. The war exacted a huge human cost in terms of fatalities, estimates of the number of Vietnamese soldiers and civilians killed vary from 966,000 to 3.8 million. Some 240, 000–300,000 Cambodians,20, 000–62,000 Laotians, and 58,220 U. S. service members died in the conflict. Various names have applied to the conflict. Vietnam War is the most commonly used name in English and it has also been called the Second Indochina War and the Vietnam Conflict. As there have been several conflicts in Indochina, this conflict is known by the names of its primary protagonists to distinguish it from others. In Vietnamese, the war is known as Kháng chiến chống Mỹ. It is also called Chiến tranh Việt Nam, France began its conquest of Indochina in the late 1850s, and completed pacification by 1893. The 1884 Treaty of Huế formed the basis for French colonial rule in Vietnam for the seven decades

Richmond Shipyards
–
The four Richmond Shipyards, located in the city of Richmond, California, United States, were run by Permanente Metals and part of the Kaiser Shipyards. During World War II, Richmond built more ships than any other shipyard, the shipyards are part of the Rosie the Riveter/World War II Home Front National Historical Park, whose Rosie the Riveter memorial sits on the former grounds of Shipyard #2. Shipyard #3 is listed on the National Register of Historic Places, henry J. Kaiser had been building cargo ships for the U. S. Maritime Commission in the late 1930s. When he received orders for ships from the British government, already at war with Nazi Germany, the four Richmond Kaiser Shipyards built 747 ships during World War II, a rate never equaled. Compared to the ship built elsewhere, Richmond ships were completed in two-thirds the time. The Liberty ship SS Robert E. Peary was assembled in less than five days as a part of a competition among shipyards, by 1944, the yard routinely needed only a bit more than two weeks to assemble a Liberty ship. By the end of the war the Richmond Shipyards had built $1.8 billion worth of ships, Kaiser and his workers applied mass assembly line techniques to building the ships. This sped up construction, allowed more workers to be mobilized, during the war, thousands of men and women worked in this area in hazardous jobs. Actively recruited by Kaiser, they came from all over the United States to swell the population of Richmond from 20,000 to over 100,000 in three years. For many of them, this was the first time worked, earned money. Women and minorities entered the workforce in areas previously denied to them, however, they still faced unequal pay, were shunted off into auxiliary unions and still had to deal with prejudice and inequities. During the war, labor strikes and sit-down work stoppages eventually led to better conditions, the SS Red Oak Victory is docked nearby.

Pearl Harbor
–
Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. Much of the harbor and surrounding lands is a United States Navy deep-water naval base and it is also the headquarters of the United States Pacific Fleet. The U. S. government first obtained exclusive use of the inlet, the attack on Pearl Harbor by the Empire of Japan on December 7,1941, was the immediate cause of the United States entry into World War II. Pearl Harbor was originally a shallow embayment called Wai Momi or Puʻuloa by the Hawaiians. Puʻuloa was regarded as the home of the goddess, Kaʻahupahau. Making due allowance for legendary amplification, the estuary already had an outlet for its waters where the present gap is, during the early 19th century, Pearl Harbor was not used for large ships due to its shallow entrance. The interest of United States in the Hawaiian Islands grew as a result of its whaling, shipping and trading activity in the Pacific. As early as 1820, an Agent of the United States for Commerce and these commercial ties to the American continent were accompanied by the work of the American Board of Commissioners for Foreign Missions. American missionaries and their families became a part of the Hawaiian political body. Throughout the 1820s and 1830s, many American warships visited Honolulu, in most cases, the commanding officers carried letters from the U. S. Government giving advice on governmental affairs and of the relations of the island nation with foreign powers. In 1841, the newspaper Polynesian, printed in Honolulu, advocated that the U. S. establish a base in Hawaii for protection of American citizens engaged in the whaling industry. The British Hawaiian Minister of Foreign Affairs Robert Crichton Wyllie, remarked in 1840 that and my opinion is that the tide of events rushes on to annexation to the United States. In 1865, the North Pacific Squadron was formed to embrace the western coast, lackawanna in the following year was assigned to cruise among the islands, a locality of great and increasing interest and importance. This vessel surveyed the Northwestern Hawaiian Islands toward Japan, as a result, the United States claimed Midway Island. The Secretary of the Navy was able to write in his report of 1868. This increased activity caused the permanent assignment of at least one warship to Hawaiian waters and it also praised Midway Island as possessing a harbor surpassing Honolulus. In the following year, Congress approved an appropriation of $50,000 on March 1,1869, after 1868, when the Commander of the Pacific Fleet visited the islands to look after American interests, naval officers played an important role in internal affairs. They served as arbitrators in disputes, negotiators of trade agreements and defenders of law

Ammunition
–
Ammunition is the general term used for the material fired, scattered, dropped or detonated from any weapon. The term ammunition can be traced back to the mid 17th century, broadly speaking, ammunition refers to both expendable weapons and the component parts of other weapons that create the effect on a target. Nearly all weapons will require some form of ammunition to operate, the word comes from the French la munition, which refers to the material used for war. The terms ammunition and munitions are used interchangeably, although the term munition now usually refers to both the actual weapons system alongside the ammunition required to operate it. The purpose of ammunition is to project a force against a target to have an effect. The most iconic example of ammunition is the cartridge, which all components required to deliver the weapon effect in a single package. Ammunition comes in a range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain types that enable their use across different weapons. There are also types of ammunition that are designed to have a specialized effect on a target, such as armor-piercing shells and tracer ammunition. Ammunition is commonly colored in a manner to assist in the identification. A round is a cartridge containing a projectile, propellant, primer. A shell is a form of ammunition that is fired by a large cannon or artillery piece. Before the mid-19th century, these shells were made of solid materials. However, since that time, they are often filled with high-explosives. A shot refers to a release of a weapons system. This may involve firing just one round or piece of ammunition, a dud refers to loaded ammunition that fails to function as intended, typically failing to detonate on landing. However, it can refer to ammunition that fails to fire inside the weapon, known as a misfire, or when the ammunition only partially functions. Dud ammunition, which is classified as an ordnance, is regarded as highly dangerous

Marshall Islands
–
The Marshall Islands, officially the Republic of the Marshall Islands, is an island country located near the equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the island group of Micronesia. The countrys population of 53,158 people is spread out over 29 coral atolls, comprising 1,156 individual islands and islets. The islands share maritime boundaries with the Federated States of Micronesia to the west, Wake Island to the north, Kiribati to the south-east, about 27,797 of the islanders live on Majuro, which contains the capital. Micronesian colonists gradually settled the Marshall Islands during the 2nd millennium BC, Islands in the archipelago were first explored by Europeans in the 1520s, with Spanish explorer Alonso de Salazar sighting an atoll in August 1526. Other expeditions by Spanish and English ships followed, the islands derive their name from British explorer John Marshall, who visited in 1788. The islands were known by the inhabitants as jolet jen Anij. The European powers recognized Spanish sovereignty over the islands in 1874 and they had been part of the Spanish East Indies formally since 1528. Later, Spain sold the islands to the German Empire in 1884, in World War I the Empire of Japan occupied the Marshall Islands, which in 1919 the League of Nations combined with other former German territories to form the South Pacific Mandate. In World War II, the United States conquered the islands in the Gilbert, along with other Pacific Islands, the Marshall Islands were then consolidated into the Trust Territory of the Pacific Islands governed by the US. Self-government was achieved in 1979, and full sovereignty in 1986, Marshall Islands has been a United Nations member state since 1991. The country uses the United States dollar as its currency, the majority of the citizens of the Marshall Islands are of Marshallese descent, though there are small numbers of immigrants from the United States, China, Philippines, and other Pacific islands. The two official languages are Marshallese, which is a member of the Malayo-Polynesian languages, and English, micronesians settled the Marshall Islands in the 2nd millennium BC, but there are no historical or oral records of that period. Over time, the Marshall Island people learned to navigate over long distances by canoe using traditional stick charts. Spanish explorer Alonso de Salazar was the first European to see the islands in 1526, commanding the ship Santa Maria de la Victoria, on August 21, he sighted an island at 14°N that he named San Bartolome. On September 21,1529, Álvaro de Saavedra Cerón commanded the Spanish ship Florida and he stood off a group of islands from which local inhabitants hurled stones at his ship. These islands, which he named Los Pintados, may have been Ujelang, on October 1, he found another group of islands where he went ashore for eight days, exchanged gifts with the local inhabitants and took on water. These islands, which he named Los Jardines, may have been Enewetak or Bikini Atoll

Caroline Islands
–
The Caroline Islands are a widely scattered archipelago of tiny islands in the northwestern Pacific Ocean, to the north of New Guinea. Politically they are divided between the Federated States of Micronesia in the part of the group, and Palau at the extreme western end. Historically, this area was also called Nuevas Filipinas or New Philippines as they were part of the Spanish East Indies, the Carolines span a distance of approximately 3540 kilometers, from Tobi, Palau at the westernmost point to Kosrae at the easternmost. The group consists of about 500 small coral islands, east of the Philippines, in the Pacific Ocean, most of the islands comprise low, flat coral atolls, but some rise high above sea level. Other significant populations include Filipinos and Japanese, the natives live mainly on horticulture and fishing, also supplementing their diet with many different varieties of bananas and taro, either of the swamp or purple varieties. On some islands housing continues to be built with materials including coconut thatch. The language spoken in commerce is English, but there are several indigenous languages and they traditionally believe in a Supreme Being and in a bad spirit, yet they have hardly any religious rites. Due to extensive work, Christianity is the primary religion practiced in this region of Micronesia. Master Micronesian Navigator Mau Piailug was from the Carolinian island of Satawal and he learned the traditional navigation techniques of the Weriyeng school. These techniques had been preserved while similar techniques had been forgotten partly due to the remoteness of the Carolinian Islands. In 1985 a study was made on the origin of the sidereal compass used in the Caroline Islands, different islands and island groups in the Carolines passed down unique and variant oral legends recounting the origins and early histories of their peoples. On Pohnpei, for example, pre-colonial history is divided into three eras, Mwehin Kawa or Mwehin Aramas, Mwehin Sau Deleur, and Mwehin Nahnmwarki, Pohnpeian legend recounts that the Saudeleur rulers, the first to bring government to Pohnpei, were of foreign origin. The Saudeleur centralized form of rule is characterized in Pohnpeian legend as becoming increasingly oppressive over several generations. Arbitrary and onerous demands, as well as a reputation for offending Pohnpeian deities, the Saudeleur Dynasty ended with the invasion of Isokelekel, another semi-mythical foreigner, who replaced the Saudeleur rule with the more decentralized nahnmwarki system in existence today. The Spanish explorers Toribio Alonso de Salazar and Diego de Saavedra arrived on August 22,1526, on 1 January 1528 the discoverer Álvaro de Saavedra took possession of the Uluti Islands on behalf of the King of Spain. Spanish explorers visited the archipelago in 1542,1543, and 1545, in 1565 Miguel Lopez de Legazpi, the first Governor-General of the Philippines, passed through. The name was extended to include the Palau Islands and the archipelagos which were named the Gilbert Islands, the occupation of the Caroline Islands had, as in most of the Spanish colonies, a marked religious character. A royal decree of October 19,1707 granted authorization for the sending of missionaries in several expeditions to the islands, one such expedition was made by Father Juan Antonio Cantova, who was killed

Enewetak Atoll
–
Enewetak Atoll is a large coral atoll of 40 islands in the Pacific Ocean and with its 850 people forms a legislative district of the Ralik Chain of the Marshall Islands. With a land area less than 5.85 square kilometres, its not higher than 5 metres. It is the second-westernmost atoll of the Ralik Chain and is 305 kilometres west from Bikini Atoll. Nuclear testing by the US totaling more than 30 megatons of TNT took place during the war, in 1977–1980. The Runit Dome is deteriorating and could be breached by a typhoon, the U. S. government referred to the atoll as Eniwetok until 1974, when it changed its official spelling to Enewetak. Enewetak Atoll formed atop a seamount, the seamount was formed in the late Cretaceous. This seamount is now about 4,600 feet below sea level and it is made of basalt, and its depth is due to a general subsidence of the entire region and not because of erosion. Enewetak has an elevation above sea level of 10 feet. Humans have inhabited the atoll since about 1,000 B. C, the first European visitor to Enewetak, Spanish explorer Alvaro de Saavedra, arrived on 10 October 1529. He called the island Los Jardines, in 1794 sailors aboard the British merchant sloop Walpole called the islands Browns Range. It was visited by about a dozen ships before the establishment of the German colony of the Marshall Islands in 1885. With the rest of the Marshalls, Enewetak was captured by the Imperial Japanese Navy in 1914 during World War I, the Japanese administered the island under the South Pacific Mandate, but mostly left affairs in hands of traditional local leaders until the start of World War II. The 1st Amphibious arrived on January 4,1944, combat also occurred on the main islet of Enewetak itself and on Parry Island, site of a Japanese seaplane base. Following its capture, the anchorage at Enewetak became a forward base for the U. S. Navy. The daily average of ships present during the first half of July 1944 was 488, woods, who executed the Nazi war criminals convicted at the Nuremberg Trials, was accidentally electrocuted here. Following the end of World War II, Enewetak came under the control of the United States as part of the Trust Territory of the Pacific Islands until the independence of the Marshall Islands in 1986. During its tenure, the United States evacuated the local residents many times, the atoll was used for nuclear testing as part of the Pacific Proving Grounds. Before testing commenced, the U. S. exhumed the bodies of United States servicemen killed in the Battle of Enewetak, forty-three nuclear tests were fired at Enewetak from 1948 to 1958

Ulithi
–
Ulithi is an atoll in the Caroline Islands of the western Pacific Ocean, about 191 km east of Yap. It consists of 40 islets totalling 4.5 km2, surrounding a lagoon about 36 km long and it is administered by the state of Yap in the Federated States of Micronesia. Ulithis population was 773 in 2000, there are four inhabited islands on Ulithi Atoll. They are Falalop, Asor, Mogmog, and Fedarai, Falalop is the most accessible with an air strip, a small resort hotel, gas dealership, store and one of three public high schools in Yap state. Mogmog is the seat of the chief of Ulithi Atoll though each island has its own chief. Other important islands are Losiap, Sorlen, and Potangeras, the atoll is in the westernmost of the Caroline Islands,360 miles southwest of Guam,850 miles east of the Philippines and 1,300 miles south of Tokyo. It is a volcanic atoll, with a coral reef, white sand beaches. Ulithis forty small islands barely rise above the sea, with the largest being only one-half square mile in area, however the reef runs roughly twenty miles north and south, by ten miles across, enclosing a vast anchorage with an average depth of 80 to 100 feet. Ulithi was a staging area for the U. S. Navy in the final year of the Second World War. Several sunken warships rest at the bottom of the Ulithi lagoon, including the USS Mississinewa, the sunken tanker was found to be seeping oil into the lagoon. The United States Navy responded, locating the tanker, tapping her storage tanks, the cleanup operation was completed in February 2003. The atoll offers good fishing and diving, though recent typhoons have eroded some of the reefs, census records can be misleading because population can fluctuate during the year because it is common for Ulithians to leave for work or school abroad and to return. This is particularly true during festive times like the Outer Island High School graduation ceremony, additionally, during events like weddings and funerals, Yasors population may double. Electricity is now available on islands, and the advent of video players. Occasional diving and adventure tours visit Ulithi from Yap, the first European to find Ulithi was the Portuguese navigator Diego da Rocha, for four months in 1525. Its visit was recorded by Spanish navigator Álvaro de Saavedra on board of ship Florida on 1 January 1528 and he named them Islas de los Reyes because of the sighting happening on the eve of Epiphany. It was later charted by the Spaniards as Islas de los Garbanzos and it was also visited by the Spanish expedition of Ruy López de Villalobos on 26 January 1543. Germany purchased the islands from Spain in 1899 and they were occupied in 1914 by Japan at the outset of the First World War

Philippines
–
The Philippines, officially the Republic of the Philippines, is a sovereign island country in Southeast Asia situated in the western Pacific Ocean. It consists of about 7,641 islands that are categorized broadly under three main geographical divisions from north to south, Luzon, Visayas, and Mindanao, the capital city of the Philippines is Manila and the most populous city is Quezon City, both part of Metro Manila. The Philippines has an area of 300,000 square kilometers, and it is the eighth-most populated country in Asia and the 12th most populated country in the world. As of 2013, approximately 10 million additional Filipinos lived overseas, multiple ethnicities and cultures are found throughout the islands. In prehistoric times, Negritos were some of the archipelagos earliest inhabitants and they were followed by successive waves of Austronesian peoples. Exchanges with Chinese, Malay, Indian, and Islamic nations occurred, then, various competing maritime states were established under the rule of Datus, Rajahs, Sultans or Lakans. The arrival of Ferdinand Magellan in Homonhon, Eastern Samar in 1521 marked the beginning of Hispanic colonization, in 1543, Spanish explorer Ruy López de Villalobos named the archipelago Las Islas Filipinas in honor of Philip II of Spain. With the arrival of Miguel López de Legazpi from Mexico City, in 1565, the Philippines became part of the Spanish Empire for more than 300 years. This resulted in Roman Catholicism becoming the dominant religion, during this time, Manila became the western hub of the trans-Pacific trade connecting Asia with Acapulco in the Americas using Manila galleons. Aside from the period of Japanese occupation, the United States retained sovereignty over the islands until after World War II, since then, the Philippines has often had a tumultuous experience with democracy, which included the overthrow of a dictatorship by a non-violent revolution. It is a member of the United Nations, World Trade Organization, Association of Southeast Asian Nations, the Asia-Pacific Economic Cooperation forum. It also hosts the headquarters of the Asian Development Bank, the Philippines was named in honor of King Philip II of Spain. Spanish explorer Ruy López de Villalobos, during his expedition in 1542, named the islands of Leyte, eventually the name Las Islas Filipinas would be used to cover all the islands of the archipelago. Before that became commonplace, other such as Islas del Poniente. The official name of the Philippines has changed several times in the course of its history, during the Philippine Revolution, the Malolos Congress proclaimed the establishment of the República Filipina or the Philippine Republic. From the 1898 Treaty of Paris, the name Philippines began to appear, since the end of World War II, the official name of the country has been the Republic of the Philippines. The metatarsal of the Callao Man, reliably dated by uranium-series dating to 67,000 years ago is the oldest human remnant found in the archipelago to date and this distinction previously belonged to the Tabon Man of Palawan, carbon-dated to around 26,500 years ago. Negritos were also among the archipelagos earliest inhabitants, but their first settlement in the Philippines has not been reliably dated, there are several opposing theories regarding the origins of ancient Filipinos

United States 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.

Military Sea Transport Service
–
The Military Sealift Command is a United States Navy organization that controls the replenishment and military transport ships of the Navy. The United States Military Sealift Command has the responsibility for providing sealift and it first came into existence on 9 July 1949 when the Military Sea Transportation Service became solely responsible for the Department of Defenses ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970, Military Sealift Command ships are made up of a core fleet of ships owned by the United States Navy and others under long-term-charter augmented by short-term or voyage-chartered ships. Some ships may have Navy or Marine Corps personnel on board to carry out communication and special mission functions, ships on charter or equivalent, retain commercial colors and bear the standard merchant prefix MV, SS, or GTS, without hull numbers. Five programs comprise Military Sealift Command, Combat Logistics Force, Special Mission, Prepositioning, Service Support, the Combat Logistics Force’s role is to directly replenish ships that are underway at sea, enabling them to deploy for long periods of time without having to come to port. The Special Mission program operates vessels for military and federal government tasks, such as submarine support and missile flight data collection. The Prepositioning program sustains the US militarys forward presence strategy by deploying supply ships in key areas prior to actual need, also, MSC realigned two of its four mission-driven programs and adding a fifth program. The Prepositioning and Sealift programs are unchanged by the 2012 reorganization, as of June 2013, Military Sealift Command operated around 110 ships, and employed 9,800 people. The Combat Logistics Force is the part of the MSC most associated with supporting the Navy. In 1972, a study concluded that it would be cheaper for civilians to man USN support vessels such as tankers, the CLF is the American equivalent of the British Royal Fleet Auxiliary. These MSC ships are painted gray and can be easily identified by the blue. The Combat Logistics Force was formerly called the Naval Fleet Auxiliary Force, some of its ships were transferred to the new Service Support program. Special mission ships work for several different US Navy customers, including the Naval Sea Systems Command and these ships like those of the NFAF are painted haze gray with blue and gold stack bands. Some of its ships were transferred to the new Service Support program, as a key element of sea basing, afloat prepositioning provides the military equipment and supplies for a contingency forward deployed in key ocean areas before need. The MSC Prepositioning Program supports the US Army, Navy, Air Force and Marine Corps, Prepositioning ships remain at sea, ready to deploy on short-notice the vital equipment, fuel and supplies to initially support military forces in the event of a contingency. The Prepositioning Program consists of 34 at-sea ships plus 2 aviation support ships kept in reduced operating status and these ships wear civilian livery, and are only designated USNS if government-owned, those chartered from civilian owners are either SS or MV. It consists of four government-operated ships formerly in the Special Mission program, Sealift is divided into three separate project offices, Tanker Project Office, Dry Cargo Project Office and the Surge Project Office. As a result of a 2012 organization, MSCs 12 worldwide MSC ship support units will now report to the MSC operational area commands in their areas of responsibility

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

Suisun Bay, California
–
Suisun Bay is a shallow tidal estuary in northern California. It lies at the confluence of the Sacramento and San Joaquin Rivers, forming the entrance to the Sacramento–San Joaquin River Delta, Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms an extension of Suisun Bay. The bay is directly north of Contra Costa County, the bay was named in 1811, after the Suisunes, a Native American tribe of the area. The word originates with the Patwin, on the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. In addition to the bridges at the Carquinez Strait, it is spanned in its center by the Benicia-Martinez Bridge. It is the anchorage of the Suisun Bay Reserve Fleet, a collection of U. S. Navy and merchant reserve ships, the Glomar Explorer was anchored here after recovering a sunken Soviet submarine in the mid-1970s. Many ships were removed and sold for scrap in the 1990s, in 2010, plans were announced to remove the mothball fleet in stages, with final removal by 2017. The Central Pacific Railroad built a ferry that operated between Benicia and Port Costa, California from 1879 to 1930. The ferry boats Solano and Contra Costa were removed from service when the nearby Martinez railroad bridge was completed in 1930, from 1913 until 1954 the Sacramento Northern Railway, an electrified interurban line, crossed Suisun Bay with the Ramon, a distillate-powered train ferry. Kinder Morgan pleaded guilty to operating a corroded pipeline and paid three dollars in penalties and restitution.

United States Congress
–
The United States Congress is the bicameral legislature of the federal government of the United States consisting of two chambers, the Senate and the House of Representatives. The Congress meets in the Capitol in Washington, D. C, both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a gubernatorial appointment. Members are usually affiliated to the Republican Party or to the Democratic Party, Congress has 535 voting members,435 Representatives and 100 Senators. The House of Representatives has six non-voting members in addition to its 435 voting members and these members can, however, sit on congressional committees and introduce legislation. Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, the members of the House of Representatives serve two-year terms representing the people of a single constituency, known as a district. Congressional districts are apportioned to states by using the United States Census results. Each state, regardless of population or size, has two senators, currently, there are 100 senators representing the 50 states. Each senator is elected at-large in their state for a term, with terms staggered. The House and Senate are equal partners in the legislative process—legislation cannot be enacted without the consent of both chambers, however, the Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue-raising bills, the House initiates impeachment cases, while the Senate decides impeachment cases. A two-thirds vote of the Senate is required before a person can be forcibly removed from office. The term Congress can also refer to a meeting of the legislature. A Congress covers two years, the current one, the 115th Congress, began on January 3,2017, the Congress starts and ends on the third day of January of every odd-numbered year. Members of the Senate are referred to as senators, members of the House of Representatives are referred to as representatives, congressmen, or congresswomen. One analyst argues that it is not a solely reactive institution but has played a role in shaping government policy and is extraordinarily sensitive to public pressure. Several academics described Congress, Congress reflects us in all our strengths, Congress is the governments most representative body. Congress is essentially charged with reconciling our many points of view on the public policy issues of the day. —Smith, Roberts, and Wielen Congress is constantly changing and is constantly in flux, most incumbents seek re-election, and their historical likelihood of winning subsequent elections exceeds 90 percent

National Park Service
–
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational, inspirational, and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS. On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until later that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and then National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States. In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was later returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service

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

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

Heritage Documentation Programs
–
These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, in 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive program for architects, draftsmen. Guided by field instructions from Washington, D. C. the first HABS recorders were tasked with documenting a representative sampling of Americas architectural heritage, by creating an archive of historic architecture, HABS provided a database of primary source material and documentation for the then-fledgling historic preservation movement. Earlier private projects included the White Pine Series of Architectural Monographs, notable HABS photographers include Jack Boucher, who worked for the project for over 40 years. The Historic American Engineering Record program was founded on January 10,1969, by NPS, HAER documents historic mechanical and engineering artifacts. Since the advent of HAER, the program is typically called HABS/HAER. Today much of the work of HABS/HAER is done by student teams during the summer, eric DeLony headed HAER from 1971 to 2003. In October 2000, NPS and the American Society of Landscape Architects established a sister program, a predecessor, the Historic American Landscape and Garden Project, recorded historic Massachusetts gardens between 1935 and 1940. That project was funded by the Works Progress Administration, but was administered by HABS, the permanent collection of HABS/HAER/HALS are housed at the Library of Congress, which was established in 1790 as the replacement reference library of the United States Congress. It has since expanded to serve as the National Library of the United States, U. S. publishers are required to deposit a copy of every copyrighted and published work, book monograph. As a branch of the United States Government, its works are in the public domain in the US. Many images, drawings, and documents are available through the Prints and Photographs Online Catalog, including proposed, demolished, and existing structures, locales, projects, and designs.

USS Boulder Victory (AK-227)
–
USS Boulder Victory was a Boulder Victory-class cargo ship acquired by the US Navy during World War II. She carried ammunition into the Pacific Ocean war zone and, on 20 December 1944 at Manus, New Guinea, she struck a naval mine, Boulder Victory was laid down on 18 June 1944, at Richmond, California, by Permanente Metals Corporation, Yard No. On 17 October, the newly commissioned cargo ship sailed to San Francisco, California and her holds were filled by 2 November, and Boulder Victory got underway for the western Pacific. Boulder Victory received orders to transfer ammunition between these bases as needed and she made port at Eniwetok on 17 November to refuel, entered the lagoon at Ulithi on 30 November, and reached Kossol Passage on 8 December. Floating mines from that island were a constant danger, on 20 December, as Boulder Victory set out for Manus, she struck one of those mines on her port side. The explosion tore a hole in her No.3 hold that measured 18 by 32 ft, the hold contained 5-inch projectiles, but the fires started by the explosion were extinguished by the rapid rush of seawater into the space. As a consequence, only two shells exploded, leaving two 16-inch holes in the skin of the ship, Boulder Victory remained afloat, although low in the water, and, after emergency repairs to the engines, managed to get into Palau again on her own power. Her crew suffered no casualties, but the damage to the ship was so severe that her wartime operations ended, the cargo ship remained anchored at Kossol Passage unloading ammunition and cleaning debris from the hold until 8 February 1945. She then slowly steamed to Manus to unload the remainder of her cargo, finally, on 13 June, Boulder Victorys temporary repairs made her seaworthy again, and she set course via Pearl Harbor for San Francisco. On 30 June, the ship began an overhaul by United Engineering Company at Alameda, California. Boulder Victory was still in overhaul when the Japanese capitulated in August, but, on 1 September and she got underway on 10 October, to carry supplies to the occupation troops in Japan. After a refueling stop at Eniwetok, Boulder Victory continued on to Okinawa where she arrived on 30 October and she unloaded her cargo and embarked returning veterans. On 10 November, she set sail for the United States, after discharging her passengers, the ship sailed for San Francisco, where she commenced demilitarization on 5 December and was returned to the War Shipping Administration on 4 January 1946. Her name was struck from the Navy list on 21 January 1946, during 1946 and 1947, Boulder Victory was operated by Parry Navigation Company, Inc. She was then inactivated and laid up at Wilmington, North Carolina, until 1951, on 29 October 1953, she was transferred to the National Defense Reserve Fleet, at Suisun Bay, California. On 20 May 1957, American President Lines removed Boulder Victory so that the University of California could conduct thermal stress tests on her and she was returned 3 September 1957. She was removed 1 December 1983, for scrapping by C. J. W and she was scrapped in Kaohsiung, Taiwan, between 1983 and 1984
