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

SS John W. Brown
–
SS John W. Brown is a Liberty ship, one of two still operational and one of three preserved as museum ships. As a Liberty ship, she operated as a merchant ship of the United States Merchant Marine during World War II, now preserved, she is a museum ship and cruise ship berthed at Clinton Street Pier 1 in Baltimore Harbor in Maryland. John W. Brown was named after the Canadian-born American labor union leader John W. Brown, the other surviving operational Liberty ship is SS Jeremiah OBrien in San Francisco, California. A third Liberty ship, SS Hellas Victory is preserved as a museum ship in Piraeus. She completed fitting out on 19 September 1942, making her total construction time only 54 days and she required about 500,000 man-hours and cost $1,750,000 to build and was the 62nd of the 384 Liberty ships constructed at the Bethlehem-Fairfield yard. The Worthington Pump & Machine Corporation of Harrison, New Jersey, built John W. Browns vertical triple expansion steam engine, Bethlehem-Fairfield Shipyard delivered John W. Brown to her owner, the Maritime Commission, on the day of her completion. With States Marine Corporation as her agent, John W. Brown was operated initially by the War Shipping Administration. Her 14, 400-nautical mile route was designed to allow her to avoid the areas where Axis forces posed the greatest threats to shipping. After passing through the canal and reaching the Pacific Ocean, she steamed alone down the west coast of South America and she then made a 17-day independent crossing of the South Atlantic Ocean to Cape Town, South Africa, where she stopped for two days to refuel and reprovision. It took another month and a half until she could enter port at Khorramshahr, Iran, on 16 March 1943, John W. Brown got underway to return to the United States. There she joined a convoy to north to Paramaribo in Surinam, proceeded upriver to Paranam to load bauxite, then steamed to Port of Spain, Trinidad. John W. Browns maiden voyage was her one as a standard cargo ship. After completion of her conversion at Hoboken, John W. Brown returned to New York to load for her second voyage, her first as a troopship. She departed New York on 24 June 1943, steamed in convoy to Hampton Roads, Virginia, to another part of the convoy. The convoy transited the Strait of Gibraltar and entered the Mediterranean Sea on 18 July 1943, the German prisoners had all disembarked by the following day. Departing Hampton Roads in convoy on 15 September 1943, she arrived at Oran in French Algeria on 4 October 1943 after an uneventful trip and her passengers disembarked there on 6 October, and she completed unloading her cargo on 15 October. She embarked 15 officers and 346 men of the U. S. Armys 1st Armored Division and loaded 274 of the divisions vehicles, including 61 tanks. On 1 November 1943, John W. Brown departed Oran in convoy on the first of eight Mediterranean shuttle trips she would make during the voyage, after a stop at Augusta, Sicily, her convoy arrived safely at Naples, Italy, on 7 November

United States dollar
–
The United States dollar is the official currency of the United States and its insular territories per the United States Constitution. It is divided into 100 smaller cent units, the circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars. The U. S. dollar was originally commodity money of silver as enacted by the Coinage Act of 1792 which determined the dollar to be 371 4/16 grain pure or 416 grain standard silver, the currency most used in international transactions, it is the worlds primary reserve currency. Several countries use it as their currency, and in many others it is the de facto currency. Besides the United States, it is used as the sole currency in two British Overseas Territories in the Caribbean, the British Virgin Islands and Turks and Caicos Islands. A few countries use the Federal Reserve Notes for paper money, while the country mints its own coins, or also accepts U. S. coins that can be used as payment in U. S. dollars. After Nixon shock of 1971, USD became fiat currency, Article I, Section 8 of the U. S. Constitution provides that the Congress has the power To coin money, laws implementing this power are currently codified at 31 U. S. C. Section 5112 prescribes the forms in which the United States dollars should be issued and these coins are both designated in Section 5112 as legal tender in payment of debts. The Sacagawea dollar is one example of the copper alloy dollar, the pure silver dollar is known as the American Silver Eagle. Section 5112 also provides for the minting and issuance of other coins and these other coins are more fully described in Coins of the United States dollar. The Constitution provides that a regular Statement and Account of the Receipts and that provision of the Constitution is made specific by Section 331 of Title 31 of the United States Code. The sums of money reported in the Statements are currently being expressed in U. S. dollars, the U. S. dollar may therefore be described as the unit of account of the United States. The word dollar is one of the words in the first paragraph of Section 9 of Article I of the Constitution, there, dollars is a reference to the Spanish milled dollar, a coin that had a monetary value of 8 Spanish units of currency, or reales. In 1792 the U. S. Congress passed a Coinage Act, Section 20 of the act provided, That the money of account of the United States shall be expressed in dollars, or units. And that all accounts in the offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation. In other words, this act designated the United States dollar as the unit of currency of the United States, unlike the Spanish milled dollar the U. S. dollar is based upon a decimal system of values. Both one-dollar coins and notes are produced today, although the form is significantly more common

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

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

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

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

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 Armed Guard
–
United States Navy Armed Guard units were established during World War II in an attempt to provide defensive firepower to merchant ships in convoy or merchant ships traveling alone. The United States Navy Armed Guard were U. S, Armed Guard crews served on Allied merchant marine ships in every theatre of the war. Typically the crew was led by a commissioned officer, but earlier in the war chiefs. The assignment as an Armed Guardsman was often dreaded because of the constant danger, Merchant ships were slow and unwieldy despite being priority targets for enemy submarines and planes. Furthermore, merchant ships were among the slowest to receive updated equipment, early on in the war some ships only had a few machine guns installed, so the crew painted telephone poles to replicate the barrels of larger guns. The most common armament to be installed on merchant ships during the war were the MK II 20mm machine gun and the 3/50, 4/50, and 5/38 deck guns. When practicable, the Navy Armed Guard aboard a merchant ship would provide cross-training to merchant crew members in the use of the guns in the event the Navy personnel were killed or injured. The Navy Armed Guard unit would travel with the merchant ship to its destination and return Stateside on the ship, or another. The first merchant ship to make the eastbound convoy to North Russia with a Navy Armed Guard was the 3800-ton freighter SS Larranga. At the insistence of the master, Captain Cameron Dudley Simmons, she was installed with a Navy Armed Guard consisting of Ensign H. A. Axtell, Jr. Ordnance placed under their charge on the SS Larranga was one 4-inch gun, the Armed Guard crew of the SS Larranga has the distinction of being the first to fire on an enemy submarine from an armed merchant vessel.

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

Ship class
–
A ship class is a group of ships of a similar design. This is distinct from a type, which might reflect a similarity of tonnage or intended use. For example, USS Carl Vinson is an aircraft carrier of the Nimitz class. In the course of building a class of ships, design changes might be implemented, in such a case, the ships of different design might not be considered of the same class, each variation would either be its own class, or a subclass of the original class. If ships are built of a class whose production had been discontinued, ships in a class often have names linked by a common factor, e. g. Trafalgar-class submarines names all begin with T, and Ticonderoga-class cruisers are named after American battles. Ships of the class may be referred to as sister ships. The name of a ship class is most commonly the name of the lead ship. However, other systems can be used without confusion or conflict, a descriptive name may be used, for example it was decided to group destroyers made to the same design as HMS Tomahawk, all named after weapons, as the Weapon rather than Tomahawk class. In European navies a class is named after the first ship commissioned regardless of when she was ordered or laid down, the West German Navy used a three-digit type number for every class in service or in advanced project state. Modified versions were identified by a letter suffix. After the reunification of Germany the German Navy kept the system, informally, classes are also traditionally named after their lead ships. The Indonesian Navy has a naming for its ships. Moreover, the type and missions can be identified by the first number on the ships three-digit hull number, which is placed on the front bows. That project sometimes, but not always, had a metaphorical name, in addition, the ships of the class would be numbered, and that number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no name, though NATO referred to its members as Foxtrot-class submarines. The British Royal Navy has used methods of naming classes. For instance, the Amphion class is known as the A class. Most destroyer classes were known by the letter used in naming the vessels, e. g. V

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

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

Transport
–
Transport or transportation is the movement of people, animals and goods from one location to another. Modes of transport include air, rail, road, water, cable, pipeline, the field can be divided into infrastructure, vehicles and operations. Transport is important because it enables trade between people, which is essential for the development of civilizations, terminals may be used both for interchange of passengers and cargo and for maintenance. Vehicles traveling on these networks may include automobiles, bicycles, buses, trains, trucks, people, helicopters, operations deal with the way the vehicles are operated, and the procedures set for this purpose including financing, legalities and policies. In the transport industry, operations and ownership of infrastructure can be public or private, depending on the country. Passenger transport may be public, where operators provide scheduled services, freight transport has become focused on containerization, although bulk transport is used for large volumes of durable items. Transport plays an important part in growth and globalization, but most types cause air pollution. While it is subsidized by governments, good planning of transport is essential to make traffic flow. A mode of transport is a solution that makes use of a type of vehicle, infrastructure. The transport of a person or of cargo may involve one mode or several of the modes, each mode has its own advantages and disadvantages, and will be chosen for a trip on the basis of cost, capability, and route. Human powered transport, a form of transportation, is the transport of people and/or goods using human muscle-power. Modern technology has allowed machines to enhance human power, human-powered vehicles have also been developed for difficult environments, such as snow and water, by watercraft rowing and skiing, even the air can be entered with human-powered aircraft. Animal-powered transport is the use of working animals for the movement of people, humans may ride some of the animals directly, use them as pack animals for carrying goods, or harness them, alone or in teams, to pull sleds or wheeled vehicles. A fixed-wing aircraft, commonly called airplane, is a craft where movement of the air in relation to the wings is used to generate lift. The term is used to distinguish this from rotary-wing aircraft, where the movement of the lift surfaces relative to the air generates lift, a gyroplane is both fixed-wing and rotary-wing. Fixed-wing aircraft range from small trainers and recreational aircraft to large airliners, two things necessary for aircraft are air flow over the wings for lift and an area for landing. The majority of aircraft also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and passengers. While the vast majority of land and take off on land, some are capable of take off and landing on ice, snow

U-boat
–
U-boat is the anglicised version of the German word U-Boot, a shortening of Unterseeboot, literally undersea boat. While the German term refers to any submarine, the English one refers specifically to military submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy warships, they were most effectively used in an economic warfare role. Austro-Hungarian navy submarines were known as U-boats. The first submarine built in Germany, the three-man Brandtaucher, sank to the bottom of Kiel harbor on 1 February 1851 during a test dive, the inventor and engineer Wilhelm Bauer had designed this vessel in 1850, and Schweffel & Howaldt constructed it in Kiel. Dredging operations in 1887 rediscovered Brandtaucher, it was raised and put on display in Germany, there followed in 1890 the boats WW1 and WW2, built to a Nordenfelt design. The SM U-1 was a completely redesigned Karp-class submarine and only one was built, the Imperial German Navy commissioned it on 14 December 1906. It had a hull, a Körting kerosene engine. The 50%-larger SM U-2 had two torpedo tubes, the U-19 class of 1912–13 saw the first diesel engine installed in a German navy boat. At the start of World War I in 1914, Germany had 48 submarines of 13 classes in service or under construction, during that war the Imperial German Navy used SM U-1 for training. Retired in 1919, it remains on display at the Deutsches Museum in Munich, on 5 September 1914, HMS Pathfinder was sunk by SM U-21, the first ship to have been sunk by a submarine using a self-propelled torpedo. On 22 September, U-9 sank the obsolete British warships HMS Aboukir, HMS Cressy, for the first few months of the war, U-boat anticommerce actions observed the prize rules of the time, which governed the treatment of enemy civilian ships and their occupants. On 20 October 1914, SM U-17 sank the first merchant ship, surface commerce raiders were proving to be ineffective, and on 4 February 1915, the Kaiser assented to the declaration of a war zone in the waters around the British Isles. This was cited as a retaliation for British minefields and shipping blockades, under the instructions given to U-boat captains, they could sink merchant ships, even potentially neutral ones, without warning. In February 1915, a submarine U-6 was rammed and both periscopes were destroyed off Beachy Head by the collier SS Thordis commanded by Captain John Bell RNR after firing a torpedo, on 7 May 1915, SM U-20 sank the liner RMS Lusitania. The sinking claimed 1,198 lives,128 of them American civilians, munitions that it carried were thousands of crates full of ammunition for rifles, 3-inch artillery shells, and also various other standard ammunition used by infantry. The sinking of the Lusitania was widely used as propaganda against the German Empire, a widespread reaction in the U. S was not seen until the sinking of the ferry SS Sussex. The sinking occurred in 1915 and the United States entered the war in 1917, the initial U. S. response was to threaten to sever diplomatic ties, which persuaded the Germans to issue the Sussex pledge that reimposed restrictions on U-boat activity

Lend-Lease
–
This included warships and warplanes, along with other weaponry. It was signed into law on March 11,1941 and ended in September 1945, in general the aid was free, although some hardware were returned after the war. In return, the U. S. was given leases on army, Canada operated a similar smaller program under a different name. A total of $50.1 billion worth of supplies was shipped, or 17% of the total war expenditures of the U. S. In all, $31.4 billion went to Britain, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to China, and the remaining $2.6 billion to the other Allies. Reverse Lend-Lease policies comprised services such as rent on air bases that went to the U. S. and totaled $7.8 billion, of this, $6.8 billion came from the British and the Commonwealth. The terms of the agreement provided that the materiel was to be used until returned or destroyed, in practice very little equipment was returned. Supplies that arrived after the date were sold to Britain at a large discount for £1.075 billion. Canada operated a program called Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain. This program effectively ended the United States pretense of neutrality and was a step away from non-interventionist policy. Following the Fall of France in June 1940, the British Commonwealth and Empire were the forces engaged in war against Germany and Italy. During this same period, the U. S. government began to mobilize for war, instituting the first-ever peacetime draft. In the meantime, as the British began running short of money, arms, as one Roosevelt biographer has characterized it, If there was no practical alternative, there was certainly no moral one either. Britain and the Commonwealth were carrying the battle for all civilization, as the President himself put it, There can be no reasoning with incendiary bombs. In September 1940, during the Battle of Britain the British government sent the Tizard Mission to the United States, in December 1940, President Roosevelt proclaimed the U. S. would be the Arsenal of Democracy and proposed selling munitions to Britain and Canada. Isolationists were strongly opposed, warning it would lead to American involvement in what was seen by most Americans as an essentially European conflict. In time, opinion shifted as increasing numbers of Americans began to see the advantage of funding the British war against Germany, while staying out of the hostilities themselves. After a decade of neutrality, Roosevelt knew that the change to Allied support must be gradual, originally, the American position was to help the British but not enter the war

Materiel
–
Materiel, more commonly matériel in US English but also listed as the only spelling in some UK dictionaries, is military technology and supplies in military and commercial supply chain management. In a military context, materiel relates to the needs of a force to complete a specific mission. The term is often used in a general sense to describe the needs of a functioning army. It includes provisioning, cataloging, requirements determination, acquisition, distribution, maintenance, the terms materiel management, materiel control, inventory control, inventory management, and supply management are synonymous. Military materiel is often shipped to and used in severe climates without controlled warehouses, packaging and labeling often needs to meet stringent technical specifications to help ensure proper delivery and final use.

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

Soviet Union
–
The Soviet Union, officially the Union of Soviet Socialist Republics was a socialist state in Eurasia that existed from 1922 to 1991. It was nominally a union of national republics, but its government. The Soviet Union had its roots in the October Revolution of 1917 and this established the Russian Socialist Federative Soviet Republic and started the Russian Civil War between the revolutionary Reds and the counter-revolutionary Whites. In 1922, the communists were victorious, forming the Soviet Union with the unification of the Russian, Transcaucasian, Ukrainian, following Lenins death in 1924, a collective leadership and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin suppressed all opposition to his rule, committed the state ideology to Marxism–Leninism. As a result, the country underwent a period of rapid industrialization and collectivization which laid the foundation for its victory in World War II and postwar dominance of Eastern Europe. Shortly before World War II, Stalin signed the Molotov–Ribbentrop Pact agreeing to non-aggression with Nazi Germany, in June 1941, the Germans invaded the Soviet Union, opening the largest and bloodiest theater of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at battles such as Stalingrad. Soviet forces eventually captured Berlin in 1945, the territory overtaken by the Red Army became satellite states of the Eastern Bloc. The Cold War emerged by 1947 as the Soviet bloc confronted the Western states that united in the North Atlantic Treaty Organization in 1949. Following Stalins death in 1953, a period of political and economic liberalization, known as de-Stalinization and Khrushchevs Thaw, the country developed rapidly, as millions of peasants were moved into industrialized cities. The USSR took a lead in the Space Race with Sputnik 1, the first ever satellite, and Vostok 1. In the 1970s, there was a brief détente of relations with the United States, the war drained economic resources and was matched by an escalation of American military aid to Mujahideen fighters. In the mid-1980s, the last Soviet leader, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost. The goal was to preserve the Communist Party while reversing the economic stagnation, the Cold War ended during his tenure, and in 1989 Soviet satellite countries in Eastern Europe overthrew their respective communist regimes. This led to the rise of strong nationalist and separatist movements inside the USSR as well, in August 1991, a coup détat was attempted by Communist Party hardliners. It failed, with Russian President Boris Yeltsin playing a role in facing down the coup. On 25 December 1991, Gorbachev resigned and the twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states

Shipyard
–
A shipyard is a place where ships are repaired and built. These can be yachts, military vessels, cruise liners or other cargo or passenger ships, dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles. The shipbuilding industry tends to be fragmented in Europe than in Asia. In European countries there are a number of small companies. The publicly owned shipyards in the US are Naval facilities providing basing, support, Shipyards are constructed nearby the sea or tidal rivers to allow easy access for their ships. Sir Alfred Yarrow established his yard by the Thames in Londons Docklands in the late 19th century before moving it northwards to the banks of the Clyde at Scotstoun. Other famous UK shipyards include the Harland and Wolff yard in Belfast, Northern Ireland, where Titanic was built, and the naval dockyard at Chatham, England on the Medway in north Kent. The site of a large shipyard will contain many specialised cranes, dry docks, slipways, dust-free warehouses, painting facilities, after a ships useful life is over, it makes its final voyage to a shipbreaking yard, often on a beach in South Asia. Historically shipbreaking was carried on in drydock in developed countries, but high wages, the worlds earliest known dockyards were built in the Harappan port city of Lothal circa 2600 BC in Gujarat, India. Lothal engineers accorded high priority to the creation of a dockyard, the dock was built on the eastern flank of the town, and is regarded by archaeologists as an engineering feat of the highest order. It was located away from the current of the river to avoid silting. The name of the ancient Greek city of Naupactus means shipyard, Naupactus reputation in this field extends to the time of legend, where it is depicted as the place where the Heraclidae built a fleet to invade the Peloponnesus. During its time of operation it was changed, rebuilt and modified. It is currently a maritime museum, ships were the first items to be manufactured in a factory, several hundred years before the Industrial Revolution, in the Venice Arsenal, Venice, Italy. The Arsenal apparently mass-produced nearly one every day using pre-manufactured parts. Chantiers de lAtlantique – established in 1861 Nantes-Indret, France – Establish in 1771 it built ships for the American Revolution including the Deane, jean Street Shipyard 1843–present – The oldest continually operated shipyard in the U. S. Located on the Hillsborough River in Tampa, Florida, Gloucester Marine Railways 1859–present – Oldest working shipyard in New England

Hog Islander
–
Hog Islanders is the slang for ships built to Emergency Fleet Corporation designs number 1022 and 1024. These vessels were cargo and transport ships, respectively, built under government direction and subsidy to address a shortage of ships in the United States Merchant Marine during World War I. No ships were produced in time to participate in World War I, Emergency Fleet Corporation was formed by the US Shipping Board to acquire, design and build sufficient shipping for the US to conduct operations in World War I. The EFC found that US shipyards were too few and small to meet the needs, contracts were awarded to foreign yards in Japan, the EFC also contracted with private companies to form new yards, called Agency Yards. These would be assembly yards, building prefabricated ships, rather than using traditional methods, Hog Island in Philadelphia, Pennsylvania, was the first shipyard ever built for mass production of ships from fabricated parts and sub-assemblies, produced at dozens of subcontractors. It had 50 slipways, seven wet docks and a detention basin, only two basic designs, EFC1022 and EFC1024, were to be fabricated at the yard, these became collectively known as Hog Islanders. The Type A design was a carrier and the Type B was designed to transport troops. Both were simple designs geared toward mass production and aesthetic considerations were ignored and these were very modern in design except for the aesthetics. The vessels were fueled by oil rather than coal, with geared turbines of 2,500 shaft horsepower capable of producing up to 15 knots. The design had a minimum of frills with no sheer, resulting in a squat, the hulls were symmetrical from the sides. The combination produced an unconventional look and profile and these ships were considered ugly but well built and had good performance in terms of capacity and speed. The Hog Island contract was for 180 ships, but only 122 were completed, the first ship, SS Quistconck, was launched on 5 August 1918, and the last of 122 ships on 29 January 1921. Though not effective in World War I, these ships were used extensively by the military, fifty-eight, nearly half, of the Hog Islanders were sunk during World War II. The Liberty ships built during World War II used a concept of production. Only 24 Type B troop transports were produced, twelve of the Type B ships were built with 8, 400-ton displacements, one of which became the US Navy USS Argonne. Another twelve were built with 13, 400-ton displacements, an example of which was the US Navy hospital ship USS Samaritan, which was active in World War II.

Rosie the Riveter
–
Rosie the Riveter is a cultural icon of the United States, representing the American women who worked in factories and shipyards during World War II, many of whom produced munitions and war supplies. These women sometimes took entirely new jobs replacing the workers who were in the military. Rosie the Riveter is used as a symbol of feminism and womens economic power, similar images of women war workers appeared in other countries such as Britain and Australia. Rosie the Riveter became the subject and title of a song, during World War I women across the United States were employed in jobs previously done by men. Nearly 19 million women held jobs during World War II, many of these women were already working in a lower paying job or were returning to the work force after being laid off during the depression. Only three million new workers entered the workforce during the time of the war. Although most women took on male dominated trades during World War II, one government advertisement asked women, Can you use an electric mixer. If so, you can learn to operate a drill, propaganda was also directed at their husbands, many of whom were unwilling to support such jobs. Many of the women who took jobs during World War II were mothers and these women with children at home pooled together in their efforts to raise their families. They assembled into groups and shared such chores as cooking, cleaning and washing clothes, many who did have young children shared apartments and houses so they could save time, money, utilities and food. If they both worked, they worked different shifts so they could take turns babysitting. Taking on a job during World War II made people unsure if they should urge the women to keep acting as full-time mothers, being able to support the soldiers by making all different products made the women feel very accomplished and proud of their work. Over 6 million women got war jobs, African American, Hispanic, White, in the book A Mouthful of Rivets Vi Kirstine Vrooman shares about the time when she decided to take action and become a riveter. She got a job building B-17s on a line, she shares just how exciting it was saying. You cant believe the feeling we had, once women accepted the challenge of the workforce they continued to make strong advances towards equal rights. In 1944, when victory seemed assured for the United States, later, many women returned to traditional work such as clerical or administration positions, despite their reluctance to re-enter the lower-paying fields. However, some of these women continued working in the factories, the overall percentage of women working fell from 36% to 28% in 1947. The term Rosie the Riveter was first used in 1942 in a song of the name written by Redd Evans

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

Steam turbine
–
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884, in 1551, Taqi al-Din in Ottoman Egypt described a steam turbine with the practical application of rotating a spit. Steam turbines were described by the Italian Giovanni Branca and John Wilkins in England. The devices described by Taqi al-Din and Wilkins are today known as steam jacks, in 1672 an impulse steam turbine driven car was designed by Ferdinand Verbiest. A more modern version of car was produced some time in the late 18th century by an unknown German mechanic. The modern steam turbine was invented in 1884 by Sir Charles Parsons, the invention of Parsons steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. Parsons design was a reaction type and his patent was licensed and the turbine scaled-up shortly after by an American, George Westinghouse. The Parsons turbine also turned out to be easy to scale up. Parsons had the satisfaction of seeing his invention adopted for all major world power stations, a number of other variations of turbines have been developed that work effectively with steam. The de Laval turbine accelerated the steam to full speed before running it against a turbine blade, De Lavals impulse turbine is simpler, less expensive and does not need to be pressure-proof. It can operate with any pressure of steam, but is less efficient. He taught at the École des mines de Saint-Étienne for a decade until 1897, one of the founders of the modern theory of steam and gas turbines was Aurel Stodola, a Slovak physicist and engineer and professor at the Swiss Polytechnical Institute in Zurich. His work Die Dampfturbinen und ihre Aussichten als Wärmekraftmaschinen was published in Berlin in 1903, a further book Dampf und Gas-Turbinen was published in 1922. It was used in John Brown-engined merchant ships and warships, including liners, the present-day manufacturing industry for steam turbines is dominated by Chinese power equipment makers. Other manufacturers with minor market share include Bhel, Siemens, Alstom, GE, Doosan Škoda Power, Mitsubishi Heavy Industries, the consulting firm Frost & Sullivan projects that manufacturing of steam turbines will become more consolidated by 2020 as Chinese power manufacturers win increasing business outside of China. There are several classifications for modern steam turbines, Turbine blades are of two basic types, blades and nozzles. Blades move entirely due to the impact of steam on them and this results in a steam velocity drop and essentially no pressure drop as steam moves through the blades. A turbine composed of alternating with fixed nozzles is called an impulse turbine, Curtis turbine, Rateau turbine

Ocean ship
–
Eighteen were lost to enemy action and eight to accidents, survivors were sold postwar into merchant service. To expedite production, the type was based on an existing design, yards constructed to build the Oceans went immediately into production of Liberty hulls. Before and during construction the ships are mentioned as British Victory or victory ships as distinct from the United States variant known as the Liberty ship. On 19 December 1940 John D, each yard was estimated to need 5,000 or more workers. On 14 January 1941 groundbreaking took place for the new yard on a 48-acre site at Richmond, the sunken basins in the Maine yard were the first in the world used to mass-produce ships. The design was based on the British Sunderland Tramp, which originated in 1879 and was last built half a decade before becoming the basis for the Ocean class of freighter, the 1940 contract for the Ocean type called for them to be built in United States yards. They were all nominally 7,174 GRT with a length of 416 ft, electrical power was to be provided by single-cylinder, vertical steam engines powering two 25 kW generators. Emergency shipbuilding programs in Canada and the United States required over 700 standardized triple-expansion steam engines to be built in seventeen plants by a number of companies, a design of the North Eastern Marine Engineering Co. Ltd. General Machinery delivered its first engine to Todd California Shipbuilding Corporation for installation in Ocean Vanguard, one of the early classifications of the ship type had been as a Liberty V design, a term not apparently later used in a professional journals references. Thirty of the Oceans were built at Richmond, Californias Yard #1 by Todd-California Shipbuilding, all Oceans with name beginning with the letter V were built by means of electric welding at Richmond, California. The first Ocean type vessel launched was Ocean Vanguard on 16 August 1941, the first vessel from this yard was Ocean Liberty launched 20 December 1941. The ships, launched by flooding the construction basins and towing them to the fitting out docks, were all launched within fifteen minutes, five Ocean ships were transferred to foreign governments during the war. Eighteen ships were lost to enemy action during the war, although two were later salvaged and returned to service, eight ships were lost in accidents postwar. The Oceans served until the mid-1980s, with Ocean Athlete being scrapped in 1985, Ocean Merchant was on Chinese shipping registers as Zhan Dou 26 until 1992. 1, Richmond CA New England Shipbuilding, South Portland ME

Compound steam engine
–
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. Multiple-expansion engines employ additional cylinders, of lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804, around 1850, compound engines were first introduced into Lancashire textile mills. In a single-expansion steam engine, the steam enters the cylinder at boiler pressure through an inlet valve. The steam pressure forces the piston down the cylinder, until the valve shuts and this cut-off allows much more work to be extracted, since the expansion of the steam is doing additional work beyond that done by the steam at boiler pressure. An earlier cut-off increases the ratio, which in principle allows more energy to be extracted and increases efficiency. This temperature drop would occur if the cylinder were perfectly insulating so that no heat is released from the system. As a result, steam enters the cylinder at high temperature, the changing steam temperature alternately heats and cools the cylinder with every stroke and is a source of inefficiency which increases at higher expansion ratios. Beyond a certain point, further increasing the ratio will actually decrease efficiency due to the increased heating and cooling. A method to lessen the magnitude of this heating and cooling was invented in 1804 by British engineer Arthur Woolf, in the compound engine, high-pressure steam from the boiler first expands in a high-pressure cylinder and then enters one or more subsequent lower pressure cylinders. The complete expansion of the steam occurs across multiple cylinders and, as there is less expansion in each cylinder and this reduces the magnitude of cylinder heating and cooling, making higher expansion ratios practical and increasing the efficiency of the engine. There are other advantages, as the range is smaller, cylinder condensation is reduced. Loss due to condensation is restricted to the LP cylinder, pressure difference is less in each cylinder so there is less steam leakage at the piston and valves. The turning moment is uniform, so balancing is easier. Only the smaller HP cylinder needs to be built to withstand the highest pressure, similarly, components are subject to less strain, so they can be lighter. The reciprocating parts of the engine are lighter, reducing the engine vibrations, the compound could be started at any point in the cycle, and in the event of mechanical failure the compound could be reset to act as a simple, and thus keep running. To derive equal work from lower-pressure steam requires a larger cylinder volume as this steam occupies a greater volume, therefore, the bore, and often the stroke, are increased in low-pressure cylinders, resulting in larger cylinders. Double-expansion engines expand the steam in two stages, but this does not imply that all engines have two cylinders

Sunderland
–
Sunderland is a city at the centre of the City of Sunderland metropolitan borough, in Tyne and Wear, North East England. It is a city at the mouth of the River Wear with adjoining beaches of Roker. The etymology of Sunderland is derived from Sundered-land with the river travelling through the city as opposed to sitting upon the river, historically in County Durham, there were three original settlements on the site of modern-day Sunderland. On the north side of the river, Monkwearmouth was settled in 674 when Benedict Biscop founded the Monkwearmouth–Jarrow Abbey, opposite the monastery on the south bank, Bishopwearmouth was founded in 930. A small fishing village called Sunderland, located toward the mouth of the river was granted a charter in 1179, over the centuries, Sunderland grew as a port, trading coal and salt. Ships began to be built on the river in the 14th century, by the 19th century, the port of Sunderland had grown to absorb Bishopwearmouth and Monkwearmouth. More recently, Sunderland has seen growth as a centre for the automotive industry, science & technology. A person who is born or lives around the Sunderland area is colloquially known as a Mackem. Sunderland was created a borough of County Durham in 1835. Under the Local Government Act 1888, it was given the status of a County Borough, independence from county council control. In 1974, under the Local Government Act 1972, the county borough was abolished and its combined with that of other districts to form the Metropolitan Borough of Sunderland in Tyne. The metropolitan borough was granted city status after winning a competition in 1992 to celebrate the Queens 40th year on the throne, the population of this city taken at the 2011 Census was 275,506. Sunderland has the motto of Nil Desperandum Auspice Deo or Under Gods guidance we may neve despair Much of the city is located on a low range of running parallel to the coast. On average, it is around 80 metres above sea level, Sunderland is divided by the River Wear which passes through the middle of the city in a deeply incised valley, part of which is known as the Hylton gorge. The two road bridges connecting the north and south portions of the city are the Queen Alexandra Bridge at Pallion, to the west of the city, the Hylton Viaduct carries the A19 dual-carriageway over the Wear. Most of the suburbs of Sunderland are situated towards the west of the city centre with 70% of its living on the south side of the river. The city extends to the seafront at Hendon and Ryhope in the south, in Millfield, the streets are all associated with plants, e. g. Chester, Fern, Rose, Hyacinth etc. At 3,874 hectares, Sunderland is the 45th largest urban area in England by measure of area, according to statistics based on the 2001 census, 60% of homes in the Sunderland metropolitan area are owner occupied, with an average household size of 2.4 people

J.L. Thompson and Sons
–
J. L. Thompson and Sons was a shipyard on the River Wear, Sunderland, which produced ships from the mid-18th century until the 1980s. The world-famous Liberty Ship was among the designs to be created, produced and manufactured at the base at North Sands. The founder of J. L. Thompson and Sons was Robert Thompson, the son of a Master Mariner, as a boy he had enjoyed a busy life on the River Wear, playing among the keels, and at 18 he started work as an apprentice shipwright. He spent his evenings, however, learning draughtsmanship on his kitchen floor and, robert’s first association with North Sands came in 1820, when he joined forces with seven business associates to build a 12 keel vessel in just six weeks. But it took him another 17 years to launch his own company, unfortunately, the depression which gripped Britain at this time quickly caused the firm’s collapse, and the sons were forced to take positions at other firms. Down, but not out, Robert decided to fight back and his firm, Robert Thompson & Sons, was launched once more on 13 February 1846. It was to prove a huge success, North Sands became the new home of the firm and, with a staff of just eight, they built a brig of 12 keels – Pearl – in 11 weeks – with work starting at 4am each day. Pearl brought in a profit and helped establish the yard’s reputation for good shipbuilding. The yard’s first ship, Vencedora, soon followed, “The launch of Vencedora was the occasion of great rejoicing, ” states a centenary brochure published by Thompsons in 1946. “The apprentices followed the ancient custom and went through the ceremony of ducking and plunging into the water as soon as the ship was safely launched. Carpenters allowances at this time were a pint of beer in the forenoon for caulking, Joseph, however, quickly found himself in charge following the retirement of Robert senior and junior, as well as John, between then and 1860. Already experienced in designing vessels, he devoted his energies to furthering the business, being joined by his own sons, Robert and Joseph, the year 1870 was a particular highlight, as it saw the last wooden ship built at North Sands. It was named Peace to commemorate the end of the Franco-Prussian War, iron ships were, by now, far more popular and the crafts which had flourished in the days of sail – mast, rope and sail making - were all affected by the steamer age. Thompsons underwent an overhaul to prepare for metal vessels and in 1871, just after the finishing touches were made. By the year 1880, the firm was in possession of the entire North Sands area and its 100th vessel was launched four years later. But, as its prosperity flourished, so the health of Joseph Thompson senior and junior declined, the senior Mr Thompson died in 1893, while his son was forced to retire. The business then passed to Robert Thompson, eldest son of Joseph, the year 1896 saw the firm celebrate its Golden Jubilee in style, with ship number 336 being launched in January. The ship weighed 4,932 tonnes and measured 396 feet – a giant when compared to the original Pearl – which was just 80 ft long, World War I found Thompsons specialising in cargo vessels and Admiralty craft

Silver Line (shipping company)
–
The Silver Line was a shipping company formed in 1908, part of the British Merchant Navy. By the 1930s they were offering round the world passenger/cargo services, entirely on foreign service, the ships did not include UK ports of call. Managing owners were the S & J Thompson family, most of their merchant ships bore the name Silver followed by the name of a tree. The Second World War claimed 11 of their ships, one of them, the Silverfir, was sunk by the German battleship Scharnhorst on a voyage from Manchester to New York in 1941. Silver Line switched to tramping around the world in the 1950s, then went through several ownership changes, and by 1985, with the sale of their last ship, was no more. The Silverplane, a twin funnel vessel of 7,226 gross tons built in 1948, was sold to the Cunard Line in 1951 and renamed Alsatia II. They were sold to the Republic of China and renamed Union Freedom, the latter ship was demolished in a fiery collision with an oil barge outside New Orleans in 1969, with considerable loss of life. An associated company, Joseph L. Thompson & Sons of Sunderland, was involved in the design of the first Liberty ships that saw service in World War II and beyond. During the 1970s, Silver Line had a fleet of tankers carrying many types of cargoes. These ships often traded in the Baltic region and they were usually called Silver- plus the name of a bird of prey. Promotion on these ships could be very rapid for those prepared to serve regularly on them. Captains of 25 years of age were not uncommon, the company also had bulk carriers, tankers, OBOs and general cargo ships. The Silvermain and Silverfjord were on a run between Japan and the USA, carrying grain one way and Toyota cars the other. Barges British Merchant Navy Cargo ship J. L.

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. S. merchant shipping has been held by many agencies since 1917

Rivet
–
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a cylindrical shaft with a head on one end. The end opposite to the head is called the tail. On installation the rivet is placed in a punched or drilled hole, in other words, pounding creates a new head on the other end by smashing the tail material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the head is called the factory head and the deformed end is called the shop head or buck-tail. Because there is effectively a head on each end of a rivet, it can support tension loads, however. Bolts and screws are better suited for tension applications, solid rivets consist simply of a shaft and head that are deformed with a hammer or rivet gun. A rivet compression or crimping tool can also deform this type of rivet and this tool is mainly used on rivets close to the edge of the fastened material, since the tool is limited by the depth of its frame. A rivet compression tool does not require two people, and is generally the most foolproof way to solid rivets. Solid rivets are used in applications where reliability and safety count, a typical application for solid rivets can be found within the structural parts of aircraft. Hundreds of thousands of rivets are used to assemble the frame of a modern aircraft. Such rivets come with rounded or 100° countersunk heads, typical materials for aircraft rivets are aluminium alloys, titanium, and nickel-based alloys. Some aluminum alloy rivets are too hard to buck and must be softened by solution treating prior to being bucked, ice box aluminum alloy rivets harden with age, and must likewise be annealed and then kept at sub-freezing temperatures to slow the age-hardening process. Steel rivets can be found in structures such as bridges, cranes. The setting of these fasteners requires access to both sides of a structure, solid rivets are driven using a hydraulically, pneumatically, or electromagnetically driven squeezing tool or even a handheld hammer. Applications where only one side is accessible require blind rivets, high-strength bolts have largely replaced structural steel rivets. Indeed, the latest steel construction specifications published by AISC no longer covers their installation, the reason for the change is primarily due to the expense of skilled workers required to install high strength structural steel rivets. Whereas two relatively unskilled workers can install and tighten high strength bolts, it takes a minimum of four highly skilled riveters to install rivets, at a central location near the areas being riveted, a furnace was set up

Welding
–
In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material that cools to form a joint that is usually stronger than the base material. Pressure may also be used in conjunction with heat, or by itself, although less common, there are also solid state welding processes such as friction welding or shielded active gas welding in which metal does not melt. Some of the best known welding methods include, Oxy-fuel welding - also known as oxyacetylene welding or oxy welding, uses fuel gases and oxygen to weld and cut metals. Shielded metal arc welding – also known as stick welding or electric welding, the electrode holder holds the electrode as it slowly melts away. Slag protects the weld puddle from atmospheric contamination, gas tungsten arc welding – also known as TIG, uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from contamination by an inert shielding gas such as argon or helium. Flux-cored arc welding – almost identical to MIG welding except it uses a special tubular wire filled with flux, it can be used with or without shielding gas, submerged arc welding – uses an automatically fed consumable electrode and a blanket of granular fusible flux. The molten weld and the arc zone are protected from contamination by being submerged under the flux blanket. Electroslag welding – a highly productive, single pass welding process for thicker materials between 1 inch and 12 inches in a vertical or close to vertical position. Electric resistance welding - a welding process that produces coalescence of laying surfaces where heat to form the weld is generated by the resistance of the material. In general, an efficient method, but limited to relatively thin material, many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often a process, welding may be performed in many different environments, including in open air, under water. Welding is an undertaking and precautions are required to avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes. Until the end of the 19th century, the welding process was forge welding. Arc welding and oxyfuel welding were among the first processes to develop late in the century, Welding technology advanced quickly during the early 20th century as the world wars drove the demand for reliable and inexpensive joining methods. Developments continued with the invention of laser welding, electron beam welding, magnetic pulse welding. Today, the continues to advance. Robot welding is commonplace in industrial settings, and researchers continue to develop new welding methods, the history of joining metals goes back several millennia

Henry J. Kaiser
–
Henry John Kaiser was an American industrialist who became known as the father of modern American shipbuilding. He established the Kaiser Shipyards, which built Liberty ships during World War II, after which he formed Kaiser Aluminum, Kaiser organized Kaiser Permanente health care for his workers and their families. He led Kaiser-Frazer followed by Kaiser Motors, automobile companies known for the safety of their designs, Kaiser was involved in large construction projects such as civic centers and dams, and invested in real estate. With his wealth, he established the Kaiser Family Foundation, a nonprofit, non-partisan, Kaiser was born on May 9,1882, in Sprout Brook, New York, the son of Franz and Anna Marie Kaiser, ethnic German immigrants. Kaisers first job was as a boy in an Utica, New York. He worked as an apprentice photographer early in life, and was running the studio in Lake Placid by the age of twenty. He used his savings to move to Washington state on the west coast of the United States in 1906, where he started a construction company that fulfilled government contracts. Kaiser met his wife, Bess Fosburgh, the daughter of a Virginia lumberman. They married on April 8,1907, and had two children, Edgar Kaiser, Sr and Henry Kaiser, Jr, in 1914 Kaiser founded a paving company, Henry J. Kaiser Co. Ltd. one of the first to use heavy construction machinery. His firm expanded significantly in 1927 when it received a contract to build roads in Camagüey Province. In 1931 his firm was one of the contractors in building the Hoover Dam on the Colorado River. Henry Kaiser was an advocate of bringing American aid to those suffering from Nazi aggression in Europe. S. Still fretted over preserving its isolationism, many leading industrialists, such as Henry Ford, were pro-Fascist and adamantly against the US entering that conflict until December 7,1941. These ships became known as Liberty ships and were supplemented in the mid-war by improved. He became world-renowned when his teams built a ship in four days, the previous record had been 10 days for the Liberty ship Joseph M. Teal. A visit to a Ford assembly plant by one of his associates led to the decision to use welding instead of riveting for shipbuilding. Welding was advantageous in that it took less strength and it was easier to teach thousands of employees, mostly unskilled laborers, Kaiser adopted the use of subassemblies in ship construction, formerly, hundreds of laborers crowded together to complete a ship. Though this practice had been tried on the East Coast and in Britain, other Kaiser Shipyards were located in Ryan Point on the Columbia River in Washington state and on Swan Island in Portland, Oregon

Marine steam engine
–
A marine steam engine is a steam engine that is used to power a ship or boat. Reciprocating steam engines were replaced in marine applications during the 20th century by steam turbines. The first commercially successful engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the half of the 18th century greatly improved steam engine efficiency. In 1807, the American Robert Fulton built the worlds first commercially successful steamboat, simply known as the North River Steamboat, following Fultons success, steamboat technology developed rapidly on both sides of the Atlantic. The first successful transatlantic crossing by a steamship occurred in 1819 when Savannah sailed from Savannah, Georgia to Liverpool, the first steamship to make regular transatlantic crossings was the sidewheel steamer Great Western in 1838. As the 19th century progressed, marine engines and steamship technology developed alongside each other. A wide variety of reciprocating steam engines were developed over the course of the 19th century. The two main methods of classifying such engines are by connection mechanism and cylinder technology, most early marine engines had the same cylinder technology but a number of different methods of supplying power to the crankshaft were in use. Thus, early engines are classified mostly according to their connection mechanism. Some common connection mechanisms were side-lever, steeple, walking beam, however, steam engines can also be classified according to their cylinder technology. One can therefore sometimes find examples of engines which were classified under both methods, such as the walking beam. Over time, as most engines became direct-acting but cylinder technologies were growing more complex, Some of the more commonly encountered types of marine steam engine are listed in the following sections. Note that not all of these terms may have been used exclusively in relation to marine applications, the side-lever engine was the first type of steam engine to be widely adopted for marine use in Europe. The side-lever was an adaptation of the earliest form of steam engine and these levers extended, on the cylinder side, to each side of the bottom of the vertical engine cylinder. A piston rod, connected vertically to the piston, extended out of the top of the cylinder and this rod attached to a horizontal crosshead which, at each end, was connected to vertical rods. These rods connected down to the levers on each side of the cylinder and this formed the connection of the levers to the piston on the cylinder side of the engine. The other side of the levers were connected to each other with a horizontal crosstail and this crosstail in turn connected to and operated a single connecting rod, which turned the crankshaft

Gear train
–
A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term refers simply to the gearbox that uses gears and gear trains to provide speed. In British English, the term refers to the whole drivetrain, including clutch, gearbox, prop shaft, differential. In American English, however, the term more specifically to the gearbox alone. The most common use is in vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a high rotational speed, which is inappropriate for starting, stopping. The transmission reduces the engine speed to the slower wheel speed. Transmissions are also used on bicycles, fixed machines. Often, a transmission has multiple gear ratios with the ability to switch between them as speed varies and this switching may be done manually or automatically. Directional control may also be provided, single-ratio transmissions also exist, which simply change the speed and torque of motor output. The output of the transmission is transmitted via the driveshaft to one or more differentials, while a differential may also provide gear reduction, its primary purpose is to permit the wheels at either end of an axle to rotate at different speeds as it changes the direction of rotation. Conventional gear/belt transmissions are not the mechanism for speed/torque adaptation. Alternative mechanisms include torque converters and power transformation, automatic transmissions use a valve body to shift gears using fluid pressures in conjunction with an ecm. Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam engines, in support of pumping, milling, most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft. This means that the shaft of a gearbox rotates at a slower rate than the input shaft. A gearbox can be set up to do the opposite and provide an increase in speed with a reduction of torque. Some of the simplest gearboxes merely change the rotational direction of power transmission. Many typical automobile transmissions include the ability to select one of several gear ratios, in this case, most of the gear ratios are used to slow down the output speed of the engine and increase torque

Warship
–
A warship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the forces of a state. As well as being armed, warships are designed to damage and are usually faster. Unlike a merchant ship, which carries cargo, a warship typically carries weapons, ammunition. Warships usually belong to a navy, though they have also operated by individuals, cooperatives. In wartime, the distinction between warships and merchant ships is often blurred, in war, merchant ships are often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service, until the threat of piracy subsided in the 19th century, it was normal practice to arm larger merchant ships such as galleons. Warships have also often used as troop carriers or supply ships. The development of catapults in the 4th century BC and the subsequent refinement of technology enabled the first fleets of artillery-equipped warships by the Hellenistic age. During late antiquity, ramming fell out of use and the galley tactics against other ships used during the Middle Ages until the late 16th century focused on boarding. Naval artillery was redeveloped in the 14th century, but cannon did not become common at sea until the guns were capable of being reloaded quickly enough to be reused in the same battle. The size of a required to carry a large number of cannons made oar-based propulsion impossible. The sailing man-of-war emerged during the 16th century, by the middle of the 17th century, warships were carrying increasing numbers of cannon on their broadsides and tactics evolved to bring each ships firepower to bear in a line of battle. The man-of-war now evolved into the ship of the line, in the 18th century, the frigate and sloop-of-war – too small to stand in the line of battle – evolved to convoy trade, scout for enemy ships and blockade enemy coasts. During the 19th century a revolution took place in the means of propulsion, naval armament. Marine steam engines were introduced, at first as an auxiliary force, the Crimean War gave a great stimulus to the development of guns. The introduction of explosive shells soon led to the introduction of iron, the first ironclad warships, the French Gloire and British Warrior, made wooden vessels obsolete. Metal soon entirely replaced wood as the material for warship construction

Jarrow
–
Jarrow is a town in north-east England, located on the River Tyne. Historically part of County Durham, in 1974 it became part of the county of Tyne. In the 8th century, the monastery of Saint Paul in Jarrow was the home of Bede, who is regarded as the greatest Anglo-Saxon scholar and the father of English history. From the middle of the 19th century until 1935, Jarrow was a centre for shipbuilding, Jarrow had a population of 43,431 in 2011. Later spellings are Jaruum in 1158, and Jarwe in 1228, today Jarrow residents popular nickname for Jarrow is Jarra. Along with the abbey at Wearmouth, Jarrow became a center of learning and had the largest library north of the Alps, primarily due to the travels of Benedict Biscop. In 794 Jarrow became the target in England of the Vikings. The monastery was dissolved by Henry VIII. The ruins of the monastery are now associated with and partly built into the church of St. Paul. One wall of the church contains the oldest stained-glass window in the world, just beside the monastery is Bedes World, a working museum dedicated to the life and times of Bede. Bedes World also incorporates Jarrow Hall, a grade II listed building, originally three copies of the Bible were commissioned by Saint Ceolfrid in 692. This date has been established as the monastery of Wearmouth-Jarrow secured a grant of additional land to raise the 2000 head of cattle needed to produce the vellum for the Bibles pages. Saint Ceolfrid accompanied one copy on its journey to be presented to Gregory II, the book later appears in the 9th century in the Abbey of the Saviour, Monte Amiata in Tuscany, where it remained until 1786 when it passed to the Laurentian Library in Florence. Jarrow remained a town until the introduction of heavy industries like coal mining and shipbuilding. Charles Mark Palmer established a shipyard – Palmers Shipbuilding and Iron Company – in 1852, john Bowes, the first iron screw collier, revived the Tyne coal trade, and Palmers was also responsible for the first modern cargo ship, as well as a number of notable warships. Around 1,000 ships were built at the yard, they produced small fishing boats to catch eel within the River Tyne. Palmers employed as much as 80% of the working population until its closure in 1933 following purchase by National Shipbuilders Securities Ltd. This organisation had set up by Stanley Baldwins Conservative government in the 1920s

Franklin D. Roosevelt
–
Franklin Delano Roosevelt, commonly known as FDR, was an American statesman and political leader who served as the 32nd President of the United States from 1933 until his death in 1945. A Democrat, he won a record four presidential elections and emerged as a figure in world events during the mid-20th century. He directed the United States government during most of the Great Depression and he is often rated by scholars as one of the three greatest U. S. Presidents, along with George Washington and Abraham Lincoln. Roosevelt was born in 1882 to an old, prominent Dutch family from Dutchess County and he attended the elite educational institutions of Groton School, Harvard College, and Columbia Law School. At age 23 in 1905, he married Eleanor Roosevelt, and he entered politics in 1910, serving in the New York State Senate, and then as Assistant Secretary of the Navy under President Woodrow Wilson. In 1920, Roosevelt was presidential candidate James M. Coxs running mate and he was in office from 1929 to 1933 and served as a reform governor, promoting the enactment of programs to combat the depression besetting the United States at the time. In the 1932 presidential election, Roosevelt defeated incumbent Republican president Herbert Hoover in a landslide to win the presidency, Roosevelt took office while in the United States was in the midst of the worst economic crisis in its history. Energized by his victory over polio, FDR relied on his persistent optimism and activism to renew the national spirit. He created numerous programs to support the unemployed and farmers, and to labor union growth while more closely regulating business. His support for the repeal of Prohibition in 1933 added to his popularity, the economy improved rapidly from 1933–37, but then relapsed into a deep recession in 1937–38. The bipartisan Conservative Coalition that formed in 1937 prevented his packing the Supreme Court, when the war began and unemployment ended, conservatives in Congress repealed the two major relief programs, the WPA and CCC. However, they kept most of the regulations on business, along with several smaller programs, major surviving programs include the Securities and Exchange Commission, the Wagner Act, the Federal Deposit Insurance Corporation and Social Security. His goal was to make America the Arsenal of Democracy, which would supply munitions to the Allies, in March 1941, Roosevelt, with Congressional approval, provided Lend-Lease aid to Britain and China. He supervised the mobilization of the U. S. economy to support the war effort, as an active military leader, Roosevelt implemented a war strategy on two fronts that ended in the defeat of the Axis Powers and initiate the development of the worlds first atomic bomb. His work also influenced the creation of the United Nations. Roosevelts physical health declined during the war years, and he died 11 weeks into his fourth term. One of the oldest Dutch families in New York State, the Roosevelts distinguished themselves in other than politics. One ancestor, Isaac Roosevelt, had served with the New York militia during the American Revolution, Roosevelt attended events of the New York society Sons of the American Revolution, and joined the organization while he was president

Time (magazine)
–
Time is an American weekly news magazine published in New York City. It was founded in 1923 and for decades was dominated by Henry Luce, a European edition is published in London and also covers the Middle East, Africa and, since 2003, Latin America. An Asian edition is based in Hong Kong, the South Pacific edition, which covers Australia, New Zealand and the Pacific Islands, is based in Sydney, Australia. In December 2008, Time discontinued publishing a Canadian advertiser edition, Time has the worlds largest circulation for a weekly news magazine, and has a readership of 26 million,20 million of which are based in the United States. As of 2012, it had a circulation of 3.3 million making it the eleventh most circulated magazine in the United States reception room circuit, as of 2015, its circulation was 3,036,602. Richard Stengel was the editor from May 2006 to October 2013. Nancy Gibbs has been the editor since October 2013. Time magazine was created in 1923 by Briton Hadden and Henry Luce, the two had previously worked together as chairman and managing editor respectively of the Yale Daily News. They first called the proposed magazine Facts and they wanted to emphasize brevity, so that a busy man could read it in an hour. They changed the name to Time and used the slogan Take Time–Its Brief and it set out to tell the news through people, and for many decades the magazines cover depicted a single person. More recently, Time has incorporated People of the Year issues which grew in popularity over the years, notable mentions of them were Barack Obama, Steve Jobs, Matej Turk, etc. The first issue of Time was published on March 3,1923, featuring Joseph G. Cannon, the retired Speaker of the House of Representatives, on its cover, a facsimile reprint of Issue No. 1, including all of the articles and advertisements contained in the original, was included with copies of the February 28,1938 issue as a commemoration of the magazines 15th anniversary. The cover price was 15¢ On Haddens death in 1929, Luce became the dominant man at Time, the Intimate History of a Publishing Enterprise 1923–1941. In 1929, Roy Larsen was also named a Time Inc. director, J. P. Morgan retained a certain control through two directorates and a share of stocks, both over Time and Fortune. Other shareholders were Brown Brothers W. A. Harriman & Co. the Intimate History of a Changing Enterprise 1957–1983. According to the September 10,1979 issue of The New York Times, after Time magazine began publishing its weekly issues in March 1923, Roy Larsen was able to increase its circulation by utilizing U. S. radio and movie theaters around the world. It often promoted both Time magazine and U. S. political and corporate interests, Larsen next arranged for a 30-minute radio program, The March of Time, to be broadcast over CBS, beginning on March 6,1931

Liberty Fleet Day (Victory Fleet Day)
–
27 September 1941 was dubbed “Liberty Fleet Day” due to the 14 “Emergency” vessels that were launched in shipyards across the United States on that day. This fleet included the first Liberty ship SS Patrick Henry, one troop transport, a tanker, a US Navy ammunition ship, in addition, the US Navy launched two destroyers at the Boston Navy Yard. SS Adabelle Lykes SS African Planet SS Alcoa Polaris SS James McKay SS John C. Roosevelt delivered a speech at the first “Emergency” launch in Baltimore that morning, at the remaining 13 launches a recording of the President’s speech was played. Today, from dawn to dark, fourteen ships are being launched - on the Atlantic, on the Pacific and on the Gulf and among them is the first Liberty ship, while we are proud of what we are doing, this is certainly no time to be content. Our shipbuilding program - not only that of the Maritime Commission, since 1936, when the Congress enacted the present Merchant Marine Law, we have been rehabilitating a Merchant Marine which had fallen to a low level. Today we are continuing that program at accelerated speed, the shipworkers of America are doing a great job. They have made a record for efficiency and speed. With every new ship, they are striking a blow at the menace to our nation. They struck fourteen such blows today and they have caught the true spirit with which all this nation must be imbued if Hitler and other aggressors of his ilk are to be prevented from crushing us. That attitude is neither truthful nor honest and we propose that these ships sail the seas as they are intended to. We propose, to the best of our ability, to them from torpedo. The Patrick Henry, as one of the Liberty ships launched today renews that great patriots stirring demand, there shall be no death for America, for democracy, for freedom. There must be liberty, world-wide and eternal and that is our prayer—our pledge to all mankind. During the United States participation in World War II,27 September became known as “Victory Fleet Day” in America

SS Patrick Henry
–
SS Patrick Henry was the first Liberty ship launched.

Give me liberty or give me death
–
Give me liberty, or give me death. Is a quotation attributed to Patrick Henry from a speech he made to the Second Virginia Convention on March 23,1775, at St. Johns Church in Richmond, Virginia. He is credited with having swung the balance in convincing the convention to pass a resolution delivering Virginian troops for the Revolutionary War, among the delegates to the convention were future U. S. Presidents Thomas Jefferson and George Washington. The speech was not published until the Port Folio printed a version of it in 1816, the version of the speech that is known today first appeared in print in Sketches of the Life and Character of Patrick Henry, a biography of Henry by William Wirt, in 1817. There is debate among historians as to whether, and to what extent, Henry or Wirt should be credited with authorship of the speech, whatever the exact words of Henry were, there can be no doubt of their impact. According to Edmund Randolph, the convention sat in silence for several minutes afterwards. ”Edward Carrington, who was listening outside a window of the church, asked to be buried on that spot. In 1810, he got his wish. ”More immediately, the resolution, declaring the United Colonies to be independent of the Kingdom of Great Britain, passed, and Henry was named chairman of the committee assigned to build a militia. Britains royal governor, Lord Dunmore, reacted by seizing the gunpowder in the magazine at Williamsburg—Virginia’s equivalent of the battles of Lexington. Whatever the exact words of Henry were, “scholars, understandably, are troubled by the way Wirt brought into print Henry’s classic Liberty or Death speech, seemed to have burned themselves into men’s memories. Certainly its spirit is that of the orator who in 1775 so powerfully influenced Virginians. The play, Cato, a Tragedy, was popular in the Colonies and well known by the Founding Fathers, George Washington had this play performed for the Continental Army at Valley Forge. It contains the line, It is not now time to talk of aught/But chains or conquest, the phrase Liberty or Death also appears on the Culpeper Minutemen flag of 1775. The phrase appears in other nationalist contexts, the national anthem of Uruguay, Orientales, la Patria o la Tumba, contains the line ¡Libertad o con gloria morir. The motto of Greece is Liberty or Death, a popular story in Brazil relates that in 1822, the emperor Dom Pedro I uttered the famous Cry from Ipiranga, Independence or Death, when Brazil was still a colony of Portugal. In March 1941 the motto of the demonstrations in the Kingdom of Yugoslavia against signing the treaty with Nazi Germany was Better grave than slave. More recently, in China, Ren Jianyu, a 25-year-old former college student village official was given a two-year re-education through labor sentence for an online anti-CPC speech, a T-shirt of Rens saying Give me liberty or give me death.

Troopship
–
A troopship is a ship used to carry soldiers, either in peacetime or wartime. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, landing ships beach themselves and bring their troops directly ashore. Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a vessel powered by rowers and sail, to move soldiers on the Rhine. HMT Olympic even rammed and sank a U-boat during one of its wartime crossings, individual liners capable of exceptionally high speed transited without escorts, smaller or older liners with poorer performance were protected by operating in convoys. The British government aided both Cunard and the White Star Line to construct the liners RMS Mauretania, RMS Aquitania, RMS Olympic, when the vulnerability of these ships to return fire was realized most were used instead as troopship or hospital ships. RMS Queen Mary and RMS Queen Elizabeth were two of the most famous converted liners of World War II, when they were fully converted, each could carry well over 10,000 troops per trip. Queen Mary holds the record, with 15,740 troops on a single passage in late July 1943. The modified Liberties were capable of transporting up to 450,550,30 Type C4 ship-based General G. O. Squier-class, the largest carrying over 6,000 passengers. A class of Victory ship-based dedicated troopship was developed late in World War II, a total of 84 such VC2-S-AP2 hull conversions was completed. A class of Type C3 ship – comprising mainly C3-S-A2 and C3-S-A3 hulls – was also converted to dedicated troopships, at least 15 classes of Attack Transport, consisting of at least 400 ships specially equipped for landing invasion forces rather than general troop movement. The designation HMT would normally replace RMS, MV or SS for ships converted to troopship duty with the United Kingdoms Royal Navy, initially troopships adapted as attack transports were designated AP, starting in 1942 keel-up attack transports received the designation APA. In the era of the Cold War the United States designed the SS United States so that it could easily be converted from a liner to a troopship, in case of war. More recently, RMS Queen Elizabeth 2 and the SS Canberra were requisitioned by the Royal Navy to carry British soldiers to the Falklands War, by the end of the twentieth century, nearly all long-distance personnel transfer was done by airlift in military transport aircraft
