Swan Hunter
Swan Hunter, formerly known as Swan Hunter & Wigham Richardson, is a shipbuilding design, engineering, and management company, based in Wallsend, Tyne and Wear, England. At its apex, the company represented the combined forces of three powerful shipbuilding families: Swan, Hunter and Wigham Richardson. The company was responsible for some of the greatest ships of the early 20th century, most famously which held the Blue Riband for the fastest crossing of the Atlantic, and which rescued survivors from . In 2006 ''Swan Hunter'' ceased vessel construction on Tyneside, but continues to provide design engineering services. History Swan & Hunter was founded by George Burton Hunter, who formed a partnership with the widow of Charles Sheridan Swan (the owner of a Wallsend Shipbuilding business established in 1852 by Charles Mitchell) under the name in 1880. In 1903, C.S. Swan & Hunter merged with Wigham Richardson (founded by John Wigham Richardson as Neptune Works in 1860), sp ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Berbera
Berbera (; so, Barbara, ar, بربرة) is the capital of the Sahil region of Somaliland and is the main sea port of the country. Berbera is a coastal city and was the former capital of the British Somaliland protectorate before Hargeisa. It also served as a major port of the Ifat, Adal and Isaaq sultanates from the 13th to 19th centuries. In antiquity, Berbera was part of a chain of commercial port cities along the Somali seaboard. During the early modern period, Berbera was the most important place of trade in the Somali Peninsula. It later served as the capital of the British Somaliland protectorate from 1884 to 1941, when it was replaced by Hargeisa.

British Somaliland
British Somaliland, officially the Somaliland Protectorate ( so, Dhulka Maxmiyada Soomaalida ee Biritishka), was a British Empire, British protectorate in present-day Somaliland. During its existence, the territory was bordered by Italian Somalia, French Somali Coast and Ethiopian Empire, Abyssinia (temporarily Italian Ethiopia). From 1940 to 1941, it was occupied by the Kingdom of Italy, Italians and was part of Italian East Africa. On 26 June 1960, British Somaliland declared independence as the State of Somaliland. Five days later, on 1 July 1960, the State of Somaliland voluntarily political union, united with the Trust Territory of Somalia (the former Italian Somalia) to form the Somali Republic.

Italian Conquest Of British Somaliland
The Italian invasion of British Somaliland (3–19 August 1940) was part of the East African campaign (1940–1941) in which Italian, Eritrean and Somali forces of Fascist Italy entered British Somaliland and defeated its combined garrison of British, Commonwealth and colonial forces supported by Somali irregulars. The Italian victory was based on mobility and speed but was hampered by the terrain, rainy weather and British resistance. At the Battle of Tug Argan (11–15 August) Italian attacks had the advantage of artillery and the outnumbered defenders were gradually worn down and slowly outflanked, until the remaining fortified hilltops were vulnerable to being captured piecemeal. After the failure of a counter-attack towards the Mirgo Pass, the local commander, Major-General Reade Godwin-Austen had too few men to retrieve the situation and to keep open an escape route at the same time and was given permission to retreat towards Berbera. The British fought a rearguard a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Indies Station
The East Indies Station was a formation and command of the British Royal Navy. Created in 1744 by the Admiralty, it was under the command of the Commander-in-Chief, East Indies. Even in official documents, the term ''East Indies Station'' was often used. In 1941 the ships of the China Squadron and East Indies Squadron were merged to form the Eastern Fleet under the control of the Commander-in-Chief, Eastern Fleet. The China Station then ceased as a separate command. The East Indies Station was disbanded in 1958. It encompassed Royal Navy Dockyards and bases in East Africa, Middle East, India and Ceylon, and other ships not attached to other fleets. For many years under rear admirals, from the 1930s the Commander-in-Chief was often an Admiral or a Vice-Admiral. History The East Indies Station was established as a Royal Navy command in 1744. From 1831 to 1865, the East Indies and the China Station were a single command known as the East Indies and China Station. The East Ind ...

Straits Of Hormuz
The Strait of Hormuz ( fa, تنگه هرمز ''Tangeh-ye Hormoz'' ar, مَضيق هُرمُز ''Maḍīq Hurmuz'') is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points. On the north coast lies Iran, and on the south coast lies the Musandam peninsula, shared by the United Arab Emirates and Musandam Governorate, an exclave of Oman. The strait is about long, with a width varying from about to . A third of the world's liquefied natural gas and almost 25% of total global oil consumption passes through the strait, making it a highly important strategic location for international trade. Etymology The opening to the Persian Gulf was described, but not given a name, in the ''Periplus of the Erythraean Sea'', a 1st-century mariner's guide: In the 10th17th centuries AD, the Kingdom of Ormus, which seems to have given the strait its ...
