Emergency Shipbuilding Program
The Emergency Shipbuilding Program (late 1940 – September 1945) was a United States government effort to quickly build simple cargo ships to carry troops and materiel to allies and foreign theatres during World War II. Run by the U.S. Maritime Commission, the program built almost 6,000 ships. Origins By the fall of 1940, the British Merchant Navy (equivalent to the United States Merchant Marine) was being sunk in the Battle of the Atlantic by Germany's U-boats faster than the United Kingdom could replace them. Led by Sir Arthur Salter, a group of men called the British Merchant Shipping Mission came to North America from the UK to enlist U.S. and Canadian shipbuilders to construct merchant ships. As all existing U.S. shipyards capable of constructing ocean-going merchant ships were already occupied by either building ships for the U.S. Navy or for the U.S. Maritime Commission's Long Range Shipbuilding Program, which had begun three years previously to fulfill the goals se ...

SHIPS FOR VICTORY
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Bethlehem Shipbuilding Corporation
Bethlehem Steel Corporation Shipbuilding Division was created in 1905 when the Bethlehem Steel Corporation of Bethlehem, Pennsylvania, acquired the San Francisco shipyard Union Iron Works. In 1917 it was incorporated as Bethlehem Shipbuilding Corporation, Limited. The division's headquarters were moved to Quincy, Massachusetts, after acquiring the Fore River Shipyard in 1913. In 1940, Bethlehem Shipbuilding was the largest of the "Big Three" U.S. shipbuilders that could build any ship, followed by Newport News Shipbuilding & Drydock and New York Shipbuilding Corporation (New York Ship). It had four yards: Fore River, Sparrows Point, San Francisco, and Staten Island. Bethlehem expanded during World War II as a result of the Emergency Shipbuilding program administered under the United States Maritime Commission. In 1964, the now-corporate headquarters moved to Sparrows Point, Maryland, southeast of Baltimore, Maryland, whose shipyard had been acquired in 1916. The Quincy / F ...

Fire Tube Boiler
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or vert ...

Compound Engine
A compound engine is an engine that has more than one stage for recovering energy from the same working fluid, with the exhaust from the first stage passing through the second stage, and in some cases then on to another subsequent stage or even stages. Originally invented as a means of making steam engines more efficient, the compounding of engines by use of several stages has also been used on internal combustion engines and continues to have niche markets there. The stages of a compound engine may be either of differing or of similar technologies, for example: * In a turbo-compound engine, the exhaust gas from the cylinders passes through a turbine, the two stages being dissimilar. * In a compound steam locomotive, the steam passes from the high-pressure cylinder or cylinders to the low-pressure cylinder or cylinders, the two stages being similar. * In a triple-expansion steam engine, the steam passes through three successive cylinders of increasing size and decreasing pressu ...

Ocean Ship
The Ocean ships were a class of sixty cargo ships built in the United States by Todd Shipyards Corporation during the Second World War for the British Ministry of War Transport under contracts let by the British Purchasing Commission. 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, later adapted to become the Liberty ship. Yards constructed to build the Oceans went immediately into production of Liberty hulls. Before and during construction the ships are occasionally mentioned as "British Victory" or victory ships as distinct from the United States variant known as the Liberty ship. Contract and yards On 19 December 1940 John D. Reilly, president of Todd Shipyards Corporation, announced that contracts totaling $100,000,000 had been signed between two Todd affiliates and the British Purchasing Commission for the construction of sixty cargo ships with thir ...

Bechtel
Bechtel Corporation () is an American engineering, procurement, construction, and project management company founded in San Francisco, California, and headquartered in Reston, Virginia. , the ''Engineering News-Record'' ranked Bechtel as the second largest construction company in the United States. History Founding and early years Bechtel's business activities began in 1898, when cattle farmer Warren A. Bechtel moved from Peabody, Kansas, to the Oklahoma Territory to construct railroads with his team of mules. Bechtel moved his family frequently between construction sites around the western United States for the next several years, eventually moving to Oakland, California, in 1904, where he worked as the superintendent on the Western Pacific Railroad. In 1906, W. A. Bechtel won his first subcontract to build part of the Oroville-to-Oakland section of the Western Pacific Railroad. That year he bought a steam shovel, becoming a pioneer of the new technology. He painted "W.A. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John A
Sir John Alexander Macdonald (January 10 or 11, 1815 – June 6, 1891) was the first prime minister of Canada, serving from 1867 to 1873 and from 1878 to 1891. The dominant figure of Canadian Confederation, he had a political career that spanned almost half a century. Macdonald was born in Scotland; when he was a boy his family immigrated to Kingston in the Province of Upper Canada (today in eastern Ontario). As a lawyer, he was involved in several high-profile cases and quickly became prominent in Kingston, which elected him in 1844 to the legislature of the Province of Canada. By 1857, he had become premier under the colony's unstable political system. In 1864, when no party proved capable of governing for long, Macdonald agreed to a proposal from his political rival, George Brown, that the parties unite in a Great Coalition to seek federation and political reform. Macdonald was the leading figure in the subsequent discussions and conferences, which resulted in the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry J
The Henry J is an American automobile built by the Kaiser-Frazer Corporation and named after its chairman, Henry J. Kaiser. Production of six-cylinder models began in their Willow Run factory in Michigan on July 1950, and four-cylinder production started shortly after Labor Day, 1950. The official public introduction was on September 28, 1950. The car was marketed through 1954. Development The Henry J was the idea of Henry J. Kaiser, who sought to increase sales of his Kaiser automotive line by adding a car that could be built inexpensively and thus affordable for the average American in the same vein that Henry Ford produced the Model T. The goal was to attract "less affluent buyers who could only afford a used car" and the attempt became a pioneering American compact car. To finance the project, the Kaiser-Frazer Corporation received a federal government loan in 1949. This financing specified various particulars of the vehicle. Kaiser-Frazer would commit to design a vehicl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six Companies
Six Companies, Inc. was a joint venture of construction companies that was formed to build the Hoover Dam on the Colorado River in Nevada and Arizona. They later built Parker Dam, a portion of the Grand Coulee Dam, the Colorado River Aqueduct across the Mojave and Colorado Deserts to urban Southern California, and many other large projects. Hoover Dam On January 10, 1932, the Bureau of Reclamation made bid documents for the Hoover Dam construction project available to interested parties at $5 a copy (equivalent to $ in ). The government would provide the materials, and the contractor was to prepare the site and build the dam. The dam was described in minute detail, covering 100 pages of text and 76 drawings. A $2 million (equivalent to $ in ) bid bond was to accompany each bid. The winner would have to post a $5 million (equivalent to $ in ) performance bond. The contractor would have seven years to build the dam, or penalties would ensue. Because of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
