Chitose-class Aircraft Carrier
The were a class of two seaplane tenders, later converted to light aircraft carriers, of the Imperial Japanese Navy during World War II. Under the terms of the Washington Naval Treaty, the total tonnage of Japan's naval vessels was limited by class. The ''Chitose''-class ships were built as seaplane tenders, designed to make the conversion to aircraft carriers relatively easy. They served as seaplane tenders during the early part of the Pacific War. After the Battle of Midway, they were converted into light aircraft carriers. Both ships participated in the Battle of the Philippine Sea and both were sunk in the Battle of Leyte Gulf. (千歳) underwent conversion at the Sasebo Naval Yard and was completed on New Years Day, 1944. Her sister ship (千代田) was completed approximately two months earlier at the Yokosuka Naval Yard. Both ships were outfitted with a single hangar and they were widened by an additional . The added flight deck was serviced by two lifts. ''Chit ...

Kure Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Kure Naval District was established at Kure, Hiroshima in 1889, as the second of the naval districts responsible for the defense of the Japanese home islands. Along with the establishment of the navy base, a ship repair facility was also constructed, initially by moving the equipment from the Onohama shipyards near Kobe. Construction was supervised by the French engineer Louis-Émile Bertin. The first warship constructed at Kure, '' Miyako'', was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903. Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles. The battleships ''Yamato'' and '' Nagato'' were designed and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

World War II Aircraft Carriers Of Japan
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Aircraft Carrier Classes
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and pa ...

Japanese Aircraft Carrier Chiyoda
was a light aircraft carrier of the Imperial Japanese Navy during World War II. Originally constructed as the second vessel of the seaplane tenders in 1934, she continued to operate in that capacity during the Second Sino-Japanese War and the early stages of the Pacific War until her conversion into a light aircraft carrier after the Battle of Midway. She was sunk during the Battle of Leyte Gulf by a combination of naval bombers, cruiser shellfire and destroyer-launched torpedoes. Background The ''Chitose''-class seaplane tenders were procured by the Imperial Japanese Navy under the 2nd Naval Armaments Supplement Programme of 1934 as purpose-built ships, whereas their predecessors were all conversions of merchant or auxiliary ship designs. During the 1930s, the Imperial Japanese Navy made increasing use of naval aviation as scouts for its cruiser and destroyer squadrons. Due to restrictions imposed by the Washington Naval Treaty and London Naval Treaty, the number of aircraft c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Aircraft Carrier Chitose
was a warship of the Imperial Japanese Navy that served from 1938 to 1944, seeing service as a seaplane carrier and later as a light aircraft carrier during World War II. In her initial guise as a seaplane carrier, she first saw service during the Second Sino-Japanese War in 1938, and subsequently played a key role in the Imperial Japanese Navy's development of a network of seaplane bases on the islands of the Pacific Ocean. After the outbreak of World War II in the Pacific, she took part in the Philippines campaign, the Dutch East Indies campaign, the Battle of Midway, and the Guadalcanal campaign, during which she was damaged in the Battle of the Eastern Solomons and also saw service related to the Battle of Cape Esperance. ''Chitose'' was converted into a light aircraft carrier during 1943, and subsequently took part in the Battle of the Philippine Sea and the Battle of Leyte Gulf. She was sunk in the Battle off Cape Engaño, one of several actions that made up the Battle o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Laid Down
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] |
