Manitowoc Shipbuilding Company
Manitowoc Shipbuilding Company, located in Manitowoc, Wisconsin, was a major shipbuilder for the Great Lakes. It was founded in 1902, with the purchase of the "Burger & Burger Shipyard," a predecessor to The Burger Boat Company, and made mainly steel ferry, ferries and ore haulers. During World War II, it built submarines, Landing Craft Tank, tank landing craft (LCTs), and self-propelled fuel barges called "YOs". Employment peaked during the military years at 7000. The shipyard closed in 1968, when The Manitowoc Company, Manitowoc Company bought Bay Shipbuilding Company and moved their shipbuilding operation to Sturgeon Bay, Wisconsin, Sturgeon Bay. Submarine building program Shipyard President Charles C. West contacted the Bureau of Construction and Repair in 1939 to propose building destroyers at Manitowoc and transporting them through the Chicago River, Chicago Sanitary and Ship Canal, Illinois River, and Mississippi River in a floating drydock towed by the tugboat ''Minnesot ...

Chicago Sanitary And Ship Canal
The Chicago Sanitary and Ship Canal, historically known as the Chicago Drainage Canal, is a canal system that connects the Chicago River to the Des Plaines River. It reverses the direction of the Main Stem and the South Branch of the Chicago River, which now flows out of Lake Michigan rather than into it. The related Cal-Sag Channel, Calumet-Saganashkee Channel does the same for the Calumet River a short distance to the south, joining the Chicago canal about halfway along its route to the Des Plaines. The two provide the only navigation for ships between the Great Lakes Waterway and the Mississippi River system. The canal was in part built as a sewage treatment scheme. Prior to its opening in 1900, sewage from the city of Chicago was dumped into the Chicago River and flowed into Lake Michigan. The city's drinking water supply was (and remains) located offshore, and there were fears that the sewage could reach the intake and cause serious disease outbreaks. Since the sewer syst ...

James Charles Fahey
James Charles Fahey (1903–1974) was an American writer best remembered as the original compiler and publisher of the popular American reference ''The Ships and Aircraft of the United States Fleet''. ''The Ships and Aircraft of the United States Fleet'' James Fahey lived in the Bronx working as a cab driver and merchant marine sailor while he wrote for various publications on the subject of military ships and aircraft. His disappointment at editors "butchering" his manuscripts caused him to self-publish the first edition of ''Ships and Aircraft of the United States Fleet'' in 1939. He carefully compiled data from unclassified sources and had a unique talent for presenting a great deal of information in compact, tabular format. His softbound 48-page booklet sold for fifty cents, and gained public interest as World War II unfolded. An updated second edition (the '' Two Ocean Fleet Edition'') was published in the same 48-page format in 1941,Fahey, James C. ''The Ships and Aircraft ...

At that time, General George Washington came before the body convened in the new Maryland State House and resigned his commission as commander of the Continental Army. A month later, the Congress ratified the Treaty of Paris of 1783, ending the American Revolutionary War, with Great Britain recognizing the independence of the United States. The city and state capitol was also the site of the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Naval Institute
The United States Naval Institute (USNI) is a private non-profit military association that offers independent, nonpartisan forums for debate of national security issues. In addition to publishing magazines and books, the Naval Institute holds several annual conferences. The Naval Institute is based in Annapolis, Maryland. Established in 1873, the Naval Institute claimed "almost 50,000 members" in 2020, mostly active and retired personnel of the United States Navy, Marine Corps and Coast Guard. The organization also has members in over 90 countries. The organization has no official or funding ties to the United States Naval Academy or the United States Navy, though it is based on the grounds of the Naval Academy through permission granted by a 1936 Act of Congress. History The United States Naval Institute was formed on October 9, 1873, by 15 naval officers gathered at the Naval Academy's Department of Physics and Chemistry building in Annapolis to discuss, among other top ...

The settlers arrived in 1693, having followed cattle to the isolated area. The community had its own ecclesiastical so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Boat
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available, for the first time making possible motorboats with a theoretically infinite cruise range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat to complete a round-the-world tour (including a transit of the Panama Canal) using only green technologies is EcoSailin ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...

Missouri River
The Missouri River is a river in the Central United States, Central and Mountain states, Mountain West regions of the United States. The nation's longest, it rises in the eastern Centennial Mountains of the Bitterroot Range of the Rocky Mountains of southwestern Montana, then flows east and south for before entering the Mississippi River north of St. Louis, Missouri. The river drains Semi-arid climate, semi-arid Drainage basin, watershed of more than 500,000 square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces. Although a tributary of the Mississippi, the Missouri River is slightly longer and carries a comparable volume of water, though a fellow tributary (Ohio River) carries more water. When combined with the lower Mississippi River, it forms the List of rivers by length, world's fourth-longest river system. For over 12,000 years, people have depended on the Missouri River and its Tributary, tributaries as a source of sustena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing t ...
