Swift-class Coastal Patrol Craft
The Swift-class coastal patrol craft were a series of patrol vessels built for the Republic of Singapore Navy (RSN) by the Singapore Ship Building and Engineering Company (SBEC). History During expansion of the Republic of Singapore Navy's capabilities in the late 1970s, the need for a dedicated coastal patrol platform was identified in order to perform the coastal surveillance and patrol mission. This need was especially apparent in 1975 during Operation Thunderstorm, where RSN resorted to using the Sea Wolf-class missile gun boats to intercept Vietnamese boat people attempting to land in Singapore. This was deemed to be operationally inefficient as it deprived RSN of a critical surface strike asset. As a result, a contract was signed with the SBEC for 12 Coastal Patrol Craft (CPC). The first vessel, RSS Swift Warrior was launched on 8 June 1980 and all 12 vessels were commissioned on 20 October 1981 by then Defence Minister, Mr Howe Yong Chong. With the transfer of the coastal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurong
Jurong () is a major geographical region located at the south-westernmost point of the West Region of Singapore. Although mostly vaguely defined, the region's extent roughly covers the planning areas of Jurong East, Jurong West, Boon Lay, and Pioneer, along with Jurong Island in the Western Islands cluster and the southernmost portions of the Western Water Catchment. Should it be described at its greatest historical extent, the region can also include present-day Bukit Batok and Tuas. Jurong also covers several offshore islands as well, including Pulau Damar Laut and Pulau Samulun, both of which are located within the planning areas of Jurong East and Boon Lay respectively; along with the aforementioned Jurong Island. The coastline of the region on mainland Singapore, faces the strait of Selat Jurong, while the southernmost island of the region, Jurong Island, faces the strait of Selat Pandan. Jurong was first developed and heavily industrialised in the late 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrol Vessels
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine ("blue water"), estuarine ("green water"), or river (" brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti-smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost make t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic Of Singapore Navy
The Republic of Singapore Navy (RSN) is the naval service branch of the Singapore Armed Forces (SAF) responsible for defending the country against any sea-borne threats, and the protection of its sea lines of communications, that would compromise Singapore as a global trading hub. The RSN traces its origins to the Royal Navy when Singapore was still a Crown colony of the British Empire. After Singapore's independence from Malaysia in 1965, the service was formally established in 1967, and had undergone a substantial modernisation ever since—which led them into becoming the most powerful navy in Southeast Asia. The RSN conducts operations with the Malaysian and Indonesian navies to combat piracy and terrorist threats in the crowded littoral waters of the Strait of Malacca and Singapore. It also jointly operates the Fokker 50 maritime patrol aircraft with its counterparts from the Republic of Singapore Air Force (RSAF) to provide air surveillance of the seaward approache ...

Operation Thunderstorm
Operation Thunderstorm was the codename for the Singapore Armed Forces's operation to contain refugees fleeing South Vietnam following the fall of Saigon in 1975. Background Following the fall of Saigon on 30 April 1975, large numbers of South Vietnamese begun to flee Vietnam for fear of persecution heralding the arrival of the Vietnamese boat people. On 2 May 1975, the first wave of 300 refugees arrived in Singapore waters on board the vessel ''Truong Hai''. A total of up to 8,355 refugees was believed to have entered Singapore waters during this period until 14 May 1975. During this period, Operation Thunderstorm was activated by MINDEF, making Singapore one of the first countries to stop refugees from entering its coastlines. The operation involved the Republic of Singapore Air Force, Republic of Singapore Navy, Singapore Army and the then- Marine Police (now the Police Coast Guard) as well as various government authorities and agencies. Objectives The primary objective of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnamese Boat People
Vietnamese boat people ( vi, Thuyền nhân Việt Nam), also known simply as boat people, refers to the refugees who fled Vietnam by boat and ship following the end of the Vietnam War in 1975. This migration and humanitarian crisis was at its highest in 1978 and 1979, but continued into the early 1990s. The term is also often used generically to refer to the Vietnamese people who left their country in a mass exodus between 1975 and 1995 (see Indochina refugee crisis). This article uses the term "boat people" to apply only to those who fled Vietnam by sea. The number of boat people leaving Vietnam and arriving safely in another country totaled almost 800,000 between 1975 and 1995. Many of the refugees failed to survive the passage, facing danger from pirates, over-crowded boats, and storms. According to the United Nations High Commission for Refugees, between 200,000 and 400,000 boat people died at sea. The boat people's first destinations were Hong Kong and the Southeast Asian ...

Singapore
Singapore (), officially the Republic of Singapore, is a sovereign island country and city-state in maritime Southeast Asia. It lies about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repo ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are fro ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft d ... [...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 ...
