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

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

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

South Portland, Maine
–
South Portland is a city in Cumberland County, Maine, United States, and is the fourth-largest city in the state, incorporated in 1898. As of the 2010 census, the city population was 25,002, known for its working waterfront, South Portland is situated on Portland Harbor and overlooks the skyline of Portland and the islands of Casco Bay. Due to South Portlands close proximity to air, marine, rail, and highway transportation options, despite the name, South Portland was never part of the city of Portland, but rather part of Cape Elizabeth. However, both Cape Elizabeth and Portland were once part of Falmouth, Cape Elizabeth, and by default, South Portland, broke away from Falmouth in 1765. South Portland is a city of the Portland – South Portland – Biddeford metropolitan area. South Portland was first settled in 1630, and it grew to become a residential community with many farms. The village was raided by natives in Father Rales War, in 1858, the City of Portland purchased land near the Fore River for the Forest City Cemetery. On March 15,1895, it was incorporated as a town after it broke away from Cape Elizabeth, based on a disagreement on a future source of public drinking water. Three years later South Portland became a city, destined to receive its water, like Portland, from Sebago Lake. On South Portlands waterfront is Fort Preble, which is a fort established in 1808 to protect Portland Harbor. It was in operation during several American conflicts, including the United States Civil War, World War I, near Fort Preble is Spring Point Ledge Light, which was constructed by the federal government in 1897 to mark a dangerous rock ledge. In 1940, the Todd-Bath Iron Shipbuilding Corp was established to build ships for Britain. These shipyards built 236 of the 440 foot long Liberty ships, at its peak, the shipyard employed some 30,000 people, including thousands of women, who took over the jobs vacated by men going into the service. The shipyard gradually ceased operations after the war ended in 1945, remnants of the shipyards are visible, and there is a memorial to the shipyard and the workers at Bug Light Park. The park is home to Portland Breakwater Lighthouse, commonly referred to as Bug Light. On July 11,1944, at 4,45 PM, for reasons that were never fully determined, Russell lost control of the plane and crashed into a trailer park in South Portlands Brick Hill neighborhood. 19 people were killed and 20 people were injured — mostly the families of South Portland shipyard workers — making it the worst aviation accident in Maine history. A Long Creek Air Tragedy Memorial was eventually erected to commemorate the crash and honor the victims, over the last few decades, South Portland has become the retail capital of Maine

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

Bath Iron Works
–
Bath Iron Works is a major American shipyard located on the Kennebec River in Bath, Maine. Since its founding in 1884, BIW has built private, commercial and military vessels, the shipyard has built and sometimes designed battleships, frigates, cruisers and destroyers, including the Arleigh Burke class, which are currently among the worlds most advanced surface warships. Since 1995, Bath Iron Works has been a subsidiary of General Dynamics, during World War II, ships built at BIW were considered by sailors and Navy officials to be of superior toughness, giving rise to the phrase Bath-built is best-built. Bath Iron Works was incorporated in 1884 by General Thomas W. Hyde, after the war, Hyde bought a local shop that helped make windlasses and other iron hardware for the wooden ships built in Baths many shipyards. He expanded the business by improving its practices, entering new markets, by 1882, Hyde Windlass was eyeing the new and growing business of iron shipbuilding, two years later, it incorporated as Bath Iron Works. On February 28,1890, BIW won its first contract for complete vessels, the Machias, one of these 190-foot gunboats, was the first ship launched by the company. In 1892, the yard won its first commercial contract for a steel vessel, in the 1890s, the company built several yachts for wealthy sailors. In 1899, General Hyde, suffering from the Brights Disease that would kill him later that year, resigned from management of the shipyard, leaving his sons Edward and that year the shipyard began construction of the Georgia, the only battleship to be built in Bath. The ship dominated the yard for five years until its launching in 1904, the yard faced numerous challenges because of the weight of armor and weapons. In sea trials, the Georgia averaged 19.26 knots for four hours, making her the fastest ship in her class, the company continued to rely on Navy contracts, which provided 86% of the value of new contracts between 1905 and 1917. The yard also produced fishing trawlers, freighters, and yachts throughout the first half of the century, at peak production during World War II, the shipyard launched a destroyer every 17 days. Bath Iron Works ranked 50th among United States corporations in the value of World War II military production contracts, in 1981, Falcon Transport ordered two tankers, the last commercial vessels built by BIW. In 1988, the USS Samuel B, Roberts, commissioned two years earlier at Bath, survived a mine explosion that tore a hole in its engine room and flooded two compartments. Over the next two years, BIW repaired the Roberts in unique fashion, the guided missile frigate was towed to the companys dry dock in Portland, Maine, and put up on blocks, where its damaged engine room was cut out of the ship. Meanwhile, workers in Bath built a 315-ton replacement, when it was ready, the module was floated south to Portland, placed on the dry dock, slid into place under the Roberts, jacked up, and welded into place. In 2001, BIW wrapped up an effort to build an enormous concrete platform. Instead of being built on a way so that they could slide into the Kennebec at launch. This greatly reduced the work involved in building and launching the ships, the 750-foot,28, 000-ton dry dock was built by Chinas Jiangdu Yuchai Shipbuilding Company for $27 million

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

Belgium
–
Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, today, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments. Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is also a member of the Eurozone, NATO, OECD and WTO. Its capital, Brussels, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is also a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands. The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Poland
–
Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges in the south. Bordered by Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, the total area of Poland is 312,679 square kilometres, making it the 69th largest country in the world and the 9th largest in Europe. With a population of over 38.5 million people, Poland is the 34th most populous country in the world, the 8th most populous country in Europe, Poland is a unitary state divided into 16 administrative subdivisions, and its capital and largest city is Warsaw. Other metropolises include Kraków, Wrocław, Poznań, Gdańsk and Szczecin, the establishment of a Polish state can be traced back to 966, when Mieszko I, ruler of a territory roughly coextensive with that of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, and in 1569 it cemented a political association with the Grand Duchy of Lithuania by signing the Union of Lublin. This union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, Poland regained its independence in 1918 at the end of World War I, reconstituting much of its historical territory as the Second Polish Republic. In September 1939, World War II started with the invasion of Poland by Nazi Germany, followed thereafter by invasion by the Soviet Union. More than six million Polish citizens died in the war, after the war, Polands borders were shifted westwards under the terms of the Potsdam Conference. With the backing of the Soviet Union, a communist puppet government was formed, and after a referendum in 1946. During the Revolutions of 1989 Polands Communist government was overthrown and Poland adopted a new constitution establishing itself as a democracy, informally called the Third Polish Republic. Since the early 1990s, when the transition to a primarily market-based economy began, Poland has achieved a high ranking on the Human Development Index. Poland is a country, which was categorised by the World Bank as having a high-income economy. Furthermore, it is visited by approximately 16 million tourists every year, Poland is the eighth largest economy in the European Union and was the 6th fastest growing economy on the continent between 2010 and 2015. According to the Global Peace Index for 2014, Poland is ranked 19th in the list of the safest countries in the world to live in. The origin of the name Poland derives from a West Slavic tribe of Polans that inhabited the Warta River basin of the historic Greater Poland region in the 8th century, the origin of the name Polanie itself derives from the western Slavic word pole. In some foreign languages such as Hungarian, Lithuanian, Persian and Turkish the exonym for Poland is Lechites, historians have postulated that throughout Late Antiquity, many distinct ethnic groups populated the regions of what is now Poland. The most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, the Slavic groups who would form Poland migrated to these areas in the second half of the 5th century AD. With the Baptism of Poland the Polish rulers accepted Christianity and the authority of the Roman Church

Torpedo
–
Historically, it was called an automotive, automobile, locomotive or fish torpedo, colloquially called a fish. The term torpedo was originally employed for a variety of devices, from about 1900, torpedo has been used strictly to designate an underwater self-propelled weapon. Todays torpedoes can be divided into lightweight and heavyweight classes, and into straight-running, autonomous homers and they can be launched from a variety of platforms. The word torpedo comes from the name of a genus of rays in the order Torpediniformes. In naval usage, the American Robert Fulton introduced the name to refer to a gunpowder charge used by his French submarine Nautilus to demonstrate that it could sink warships. The concept of a torpedo existed many centuries before it was successfully developed. In 1275, Hasan al-Rammah described. an egg which moves itself, in modern language, a torpedo is an underwater self-propelled explosive, —but historically, the term also applied to primitive naval mines. These were used on an ad hoc basis during the modern period up to the late 19th century. An early submarine, the Turtle, attempted to lay a bomb with a fuse on the hull of HMS Eagle during the American Revolutionary War. In the early 1800s, the American inventor Robert Fulton, while in France and he coined the term torpedo in reference to the explosive charges he outfitted his submarine Nautilus. However, both the French and the Dutch governments were uninterested in the submarine, Fulton then concentrated on developing the torpedo independent of a submarine deployment. However, the British government refused to purchase the invention, stating they did not wish to introduce into naval warfare a system that would give advantage to weaker maritime nations. Fulton carried out a demonstration for the US government on 20 July 1807. Further development languished as Fulton focused on his steam-boat matters, during the War of 1812, torpedoes were employed in attempts to destroy British vessels and protect American harbors. In fact a submarine deployed torpedo was used in an attempt to destroy HMS Ramillies while in New Londons harbor. Hardy to warn the Americans to cease efforts with the use of any boat in this cruel and unheard-of warfare. Torpedoes were used by the Russian Empire during the Crimean War in 1855 against British warships in the Gulf of Finland and they used an early form of chemical detonator. During the American Civil War, the torpedo was used for what is today called a contact mine

Luftwaffe
–
The Luftwaffe was the aerial warfare branch of the combined German Wehrmacht military forces during World War II. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base, with the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe was officially established on 26 February 1935. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a testing ground for new doctrines. By the summer of 1939, the Luftwaffe had twenty-eight Geschwaders, during World War II, German pilots claimed roughly 70,000 aerial victories, while over 75,000 Luftwaffe aircraft were destroyed or significantly damaged. Of these, nearly 40,000 were lost entirely, the Luftwaffe proved instrumental in the German victories across Poland and Western Europe in 1939 and 1940. From 1942, Allied bombing campaigns gradually destroyed the Luftwaffes fighter arm, in addition to its service in the West, the Luftwaffe operated over the Soviet Union, North Africa and Southern Europe. In January 1945, during the stages of the Battle of the Bulge, the Luftwaffe made a last-ditch effort to win air superiority. After the defeat of Germany, the Luftwaffe was disbanded in 1946, the Luftwaffe had only two commanders-in-chief throughout its history, Hermann Göring and later Generalfeldmarschall Robert Ritter von Greim. Throughout the war, the force was responsible for war crimes, one of the forerunners of the Luftwaffe, the Imperial German Army Air Service, was founded in 1910 with the name Die Fliegertruppen des deutschen Kaiserreiches, most often shortened to Fliegertruppe. It was renamed Luftstreitkräfte on 8 October 1916, after the defeat of Germany, the service was dissolved on 8 May 1920 under the conditions of the Treaty of Versailles, which also mandated the destruction of all German military aircraft. Since the Treaty of Versailles forbade Germany to have an air force, to train its pilots on the latest combat aircraft, Germany solicited the help of its future enemy, the Soviet Union, which was also isolated in Europe. This base was known as 4th squadron of the 40th wing of the Red Army. Hundreds of Luftwaffe pilots and technical personnel visited, studied and were trained at Soviet air force schools in locations in Central Russia. The first steps towards the Luftwaffes formation were undertaken just months after Adolf Hitler came to power, in April 1933 the Reichsluftfahrtministerium was established. Görings control over all aspects of aviation became absolute, on 25 March 1933 the Deutschen Luftsportverband absorbed all private and national organizations, while retaining its sports title. On 15 May 1933, all military organizations in the RLM were merged, forming the Luftwaffe. The |Nationalsozialistisches Fliegerkorps was formed in 1937 to give pre-military flying training to male youths, military-age members of the NSFK were drafted to the Luftwaffe. As all such prior NSFK members were also Nazi Party members, the absence of Göring in planning and production matters was fortunate
