Taboga Island
Taboga Island ( es, Isla Taboga, links=no), also known as the "Island of Flowers", is a volcanic island in the Gulf of Panama. It is a tourist destination, about 20 km from Panama City, Panama. History The island was discovered in the 16th century and was originally named ''Isla de San Pedro'' by the Spanish explorer Vasco Núñez de Balboa. Its current name derives from an Indian word ''aboga'' ("many fish"). The island's first settlers were Indian slaves from Venezuela and Nicaragua. The small town of San Pedro was founded in 1524 by Hernando de Luque, dean of the Panama cathedral. The town church of the same name is claimed to be the second-oldest church in the hemisphere. Rose of Lima (1586–1617), the first Catholic saint of the Americas, may have been born on the island. French painter Paul Gauguin visited the island in 1887.

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 ...

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] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4"/50 Caliber Gun
The 4″/50 caliber gun (spoken "four-inch-fifty-caliber") was the standard low-angle, quick-firing gun for United States, first appearing on the monitor and then used on "Flush Deck" destroyers through World War I and the 1920s. It was also the standard deck gun on S-class submarines, and was used to rearm numerous submarines built with guns early in World War II. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long. Design The original 4-inch/50 caliber Mark 7 gun, M1898, serial nos. 213–254, 257–281, 316–338, was an entirely new high-power design built-up gun with a tube, jacket, hoop, locking ring and screw breech. Gun No. 213 had a liner. The gun was described as a gun but with a 4-inch bore in the 1902 handbook, this indicated its higher power and also the fact the barrel was actually more the size of a 5-inch/40 caliber gun than a 4-inch gun. The ammunition was about heavier than a 4-inch/40 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...
