USS Golet (SS-361)
USS ''Golet'' (SS-361), a Gato class submarine, ''Gato''-class submarine, was the only ship of the United States Navy to be named for the Dolly Varden trout, golet, a California trout. Construction and commissioning ''Golet'' initially was ordered as a unit of the Balao-class submarine, ''Balao'' class, but her builder, the Manitowoc Shipbuilding Company, did not receive the drawings for the ''Balao'' class from the Electric Boat Company in time to build ''Golet'' or the submarines , , and to the new design, so they were built as ''Gato''-class submarines. Thus, in some references, these four submarines are listed as units of the ''Balao''-class. War bond purchases by the people of Shreveport, Louisiana, Shreveport, Louisiana, and Caddo Parish, Louisiana, Cadddo Parish, Louisiana, funded ''Golet''′s construction. Her keel was Keel-laying, laid down by the Manitowoc Shipbuilding Company of Manitowoc, Wisconsin. She was Ceremonial ship launching, launched on 1 August 1943, Sh ...

Dolly Varden Trout
The Dolly Varden trout (''Salvelinus malma'') is a species of salmonid fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. It belongs to the genus ''Salvelinus'', or true chars, which includes 51 recognized species, the most prominent being the brook, lake and bull trout, as well as Arctic char. Although many populations are semi-anadromous, fluvial and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the ''Salvelinus alpinus'' or Arctic char complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap. Taxonomy The scientific name of the Dolly Varden is ''Salvelinus malma''. The species was originally named by German naturalist and taxonomist Johann Julius Walbaum in 1792 based on type specimens from the Kamchatka Peninsula in Siberia. The name ''malma'' was based on Russian , the local colloquial name for the fish. The Dolly Varden trout is considered part of the ''S. al ...

Caliber (artillery)
In artillery, caliber or calibredifference in British English and American English spelling is the internal diameter of a gun barrel, or - by extension - a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove to groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land to land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land to land dimension of the barrel and a copper driving band somewhat larger than the groove to groove diameter t ...

Keel-laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

War Bond
War bonds (sometimes referred to as Victory bonds, particularly in propaganda) are debt securities issued by a government to finance military operations and other expenditure in times of war without raising taxes to an unpopular level. They are also a means to control inflation by removing money from circulation in a stimulated wartime economy. War bonds are either retail bonds marketed directly to the public or wholesale bonds traded on a stock market. Exhortations to buy war bonds have often been accompanied by appeals to patriotism and conscience. Retail war bonds, like other retail bonds, tend to have a yield which is below that offered by the market and are often made available in a wide range of denominations to make them affordable for all citizens. Before World War I Governments throughout history have needed to borrow money to fight wars. Traditionally they dealt with a small group of rich financiers such as Jakob Fugger and Nathan Rothschild, but no particular distin ...

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 EcoSail ...

Balao-class Submarine
The ''Balao'' class was a successful design of United States Navy submarine used during World War II, and with 120 boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier , the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to . ''Tang'' actually achieved a depth of during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer. Design The ''Balao''s were similar to the ''Gato''s, except they were modified to increase test depth from to . In late 1941, two of the Navy's leading submarine designers, Captain Andrew McKee and Commander Armand Morgan, met to explore increasing diving depth in a redesigned ''Gato''. A switch to a new High-Tensile Steel (HTS) alloy, combined with an increase in hull thickness from to , wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
