ROKS Marado
ROKS ''Marado'' (LPH-6112) is the second ship of the of the Republic of Korea Navy. Differences with ROKS ''Dokdo'' ''Marado'' was built with some changes compared to the lead ship . The flight deck is adapted to accommodate two V-22 Ospreys, while ''Dokdo'' was able to only carry one. In place of the Thales SMART-L multibeam radar and MW08 surveillance radar, ''Marado'' uses the Elta Systems EL/M-2248 MF-STAR multifunction surveillance radar and LIG Nex1 SPS-550K 3-D air and surface surveillance radar. It also has a different weapons suite than the 30 mm Goalkeeper and RAM, instead using two 20 mm Phalanx CIWS and having a K-VLS at the rear of the superstructure for the locally developed K-SAAM. Construction and Career The ''Marado'' was launched on 14 May 2018 at the shipyard of Hanjin Heavy Industries & Constructions Co. in Busan. The Marado was commissioned on 28 June 2021 and is based at the Jinhae Naval Base. ''Marado'' was originally planned to enter se ...

Marado
Marado or Mara Island is an island off the south coast of Jeju, in southernmost South Korea, having an area of . It is home to about 90 people, and has long been known for its population being composed of strong women and docile men. It's becoming a popular tourist destination, thanks to the many unusual rock formations, and is connected to the mainland by two regular ferries and numerous excursion boats. Mara-do is within the administrative boundaries of Daejeong Township ( Daejeong-eup) in Seogwipo City, and is included, along with Gapa Island (Gapado), in Gapa-ri, and is South Korea's southernmost point. Because of its subtropical marine habitat the island is a natural reserve. It was designated as National Monument no. 423 (천연기념물 제423호) on July 18, 2000. Overview Marado was originally uninhabited. It was known as Keumdo (금도,禁島), which means forbidden island. According to a Choson Ilbo article published by Lee Kyu-tae in 1967, the island was first o ...

V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. In 1980, the failure of Operation Eagle Claw (during the Iran hostage crisis) underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited. The United States Department of Defense (DoD) initiated a program to develop an innovative transport aircraft with long-range, high-speed, and vertical-takeoff capabilities, and the Joint-service Vertical take-off/landing Experimental (JVX) program officially commenced in 1981. A partnership between Bell Helicopter and Boeing Helicopters was awarded a development contract in 1983 for the V-22 tiltrotor aircraft. The Bell Boeing team joint ...

ROKS Shin Dol-seok (SS-082)
ROKS ''Shin Dol-seok'' (SS-082) is the ninth boat of the ''Sohn Won-yil''-class submarine in the Republic of Korea Navy. She is named after the general, Shin Dol-seok. Design There are media reports that the ''Sohn Won-yil'' is equipped with eight 533 mm torpedo tubes, and that South Korea will mount a Korean Tomahawk missile, Hyunmoo-3, with a range of 500 km. It is said that they are also developing versions with a range of 1000 km and 1500 km, but there was no confirmation of whether this version could be mounted on a 533mm torpedo tube. Originally, the American Tomahawk missile was conceptually designed to be launched from a 533mm torpedo tube. Korea has also recently succeeded in localizing it. The Cheonryong missile with a range of 500 km has been installed in the ''Sohn Won-yil''-class and has been deployed and is in operation. Germany, which exported the ''Sohn Won-yil''-class ( class 214), is using a Type 212 submarine that uses the same AIP system with the same di ...

Type 214
The Type 214 is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class is exclusively designed for export market. The submarine class combines the design principles of the Type 209 family and the features of the Type 212A submarines. However, as an export design, it lacks some of the classified technologies of the smaller Type 212, the most important of which is probably the non-magnetic steel hull, which makes the Type 212 submarine difficult to detect using a magnetic anomaly detector. Due to improvements in the pressure hull materials, the Type 214 can dive nearly . It can also carry food, fresh water and fuel for 84 days of operation. A contract to build four boats for the Hellenic Navy was signed 15 February 2000 and a fourth unit was ordered in June 2002. The first boat was built at HD ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fitting-out
Fitting out, or outfitting, is the process in shipbuilding that follows the float-out/launching of a vessel and precedes sea trials. It is the period when all the remaining construction of the ship is completed and readied for delivery to her owners. Since most of the fitting-out process is interior work, this stage can overlap with latter stages, such as the sea trials. Launching or floating After a vessel has been floated (in contemporary shipbuilding) or launched (in traditional shipbuilding), it is then towed out of its drydock and moored at a fitting-out berth. While still afloat, its construction is then continued. Depending on the type of vessel, fitting-out can last weeks or many months. Vessels with comparatively little space for human occupation, such as oil tankers, bulk carriers and container ships, can take the least time for fitting. Conversely, passenger ships take the longest. The process can include: * completion of the superstructure, * installation of the ship ...

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 ...

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] |
Great Recession
The Great Recession was a period of marked general decline, i.e. a recession, observed in national economies globally that occurred from late 2007 into 2009. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression. One result was a serious disruption of normal international relations. The causes of the Great Recession include a combination of vulnerabilities that developed in the financial system, along with a series of triggering events that began with the bursting of the United States housing bubble in 2005–2012. When housing prices fell and homeowners began to abandon their mortgages, the value of mortgage-backed securities held by investment banks declined in 2007–2008, causing several to collapse or be bailed out in September 2008. This 2007–2008 phase was called the subprime mortgage crisis. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanjin
The Hanjin Group () is a South Korean chaebol. The group has various industries covered from transportation and airlines to hotels, tourism, and airport businesses, and one of the largest chaebols in Korea. The group includes Korean Air (KAL), which was acquired by the founder Cho Choong-hoon in 1969, and was the owner of Hanjin Shipping (once the largest shipping company in Korea) before its bankruptcy. In 2013, Hanjin Group officially switched from cross ownership to a holding company structure with the establishment of Hanjin KAL Corporation. The group is controlled by descendants of Cho Choong-hoon, and many construction chaebols are the major shareholders of Hanjin KAL.

Jane's Information Group
Jane's Information Group, now styled Janes, is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, The Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019.
