HMAS Kangaroo
HMAS ''Kangaroo'' was a Bar-class boom defence vessel of the Royal Australian Navy (RAN). Although originally ordered as a boom vessel, ''Kangaroo'' was at one point to be built as the prototype for what became the ''Bathurst'' class corvettes, but reverted to the boom defence design before construction started. Launched in 1940, the ship spent most of World War II operating the anti-submarine net in Darwin. ''Kangaroo'' remained in service until 1955, and after several years as an accommodation ship, was sold for scrapping in 1967. Design and construction In 1937, three ships were ordered by the RAN for use as Boom Defense Vessels.Stevens, ''A Critical Vulnerability'', p. 103 The plan was altered in early 1938 to require only two ships; the third, ''Kangaroo'' was earmarked to be constructed as a prototype local defense vessel. The RAN's Director of Engineering was instructed to prepare plans for the ship in July 1938, which were completed six months later.Stevens, ''A Criti ...

HMAS Kangaroo SLV AllanGreen
His Majesty's Australian Ship (HMAS) (or Her Majesty's Australian Ship when the monarch is female) is a ship prefix used for commissioned units of the Royal Australian Navy (RAN). This prefix is derived from HMS (Her/His Majesty's Ship), the prefix used by the Royal Navy of the United Kingdom, and can be equally applied to warships and shore bases (as Australia follows the British tradition of referring to naval establishments as stone frigates). On 10 July 1911, King George V granted the title of Royal Australian Navy to the naval forces of Australia. At the same time, the prefix and acronym were approved for use in identifying units commissioned into the RAN. The prefix had been used prior to formal approval, with the torpedo-boat destroyer In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally develo ... [...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] |

Bombing Of Darwin (February 1942)
The Bombing of Darwin, also known as the Battle of Darwin, on 19 February 1942 was the largest single attack ever mounted by a foreign power on Australia. On that day, 242 Japanese aircraft, in two separate raids, attacked the town, ships in Darwin's harbour and the town's two airfields in an attempt to prevent the Allies from using them as bases to contest the invasion of Timor and Java during World War II. Darwin was lightly defended relative to the size of the attack, and the Japanese inflicted heavy losses upon Allied forces at little cost to themselves. The urban areas of Darwin also suffered some damage from the raids and there were a number of civilian casualties. More than half of Darwin's civilian population left the area permanently, before or immediately after the attack. The two Japanese air raids were the first, and largest, of more than 100 air raids against Australia during 1942–1943. The event happened just four days after the Fall of Singapore, when a c ...

Darwin Harbour
Darwin Harbour is the body of water close to Darwin in the Northern Territory of Australia. It opens to the north at a line from Charles Point in the west to Lee Point in the east into the Beagle Gulf and connects via the Clarence Strait with the Van Diemen Gulf.N Smit, R Billyard and L Ferns: Beagle Gulf Benthic Survey: Characterisation of soft substrates.'' Technical Report No. 66 (2000), Parks and Wildlife Commission of the Northern Territory. It contains Port Darwin, which is flanked by Frances Bay to the east and Cullen Bay to the west. Name Darwin Harbour was named after the naturalist Charles Darwin, who sailed with captain Robert Fitzroy on the second expedition of the ''Beagle'' (December 1831 – October 1836) which visited parts of Australia. During the voyage, he became a friend of the officers, including John Lort Stokes and John Clements Wickham who were promoted for the next voyage of the ship. Lieutenant Stokes was apparently the first British person to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockatoo Docks And Engineering Company
The Cockatoo Docks & Engineering Company was a ship building and maintenance company which operated the Cockatoo Island Dockyard on Cockatoo Island in Sydney, Australia between 1933 and 1992. History The Cockatoo Docks & Engineering Company commenced trading on 1 March 1933 taking a 21-year lease over the dockyard on Cockatoo Island from the Federal Government. Having held a minority shareholding since 1937, in 1947 Vickers-Armstrongs became the majority shareholder. In February 1954, the lease was renewed for a further 20 years and 8 months, and again from 1 January 1972 for 21 years. In February 1984, Vickers merged its Australian interests were with the Commonwealth Steel Company to form Comsteel Vickers, Vickers and BHP each owning 38%, with the remaining 24% held by smaller investors. On 4 June 1986, the company was purchased by Australian National Industries (ANI). As part of a review of Australia's ship building capabilities, the Federal Government decided in 1987 th ...

Asdic
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to 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) to extrem ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Darwin, Northern Territory
Darwin ( ; Larrakia: ) is the capital city of the Northern Territory, Australia. With an estimated population of 147,255 as of 2019, the city contains the majority of the residents of the sparsely populated Northern Territory. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre. Darwin's proximity to Southeast Asia makes the city's location a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point in the north and stretch to Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston and its suburbs. The Darwin region, like much of the Top End, experiences a tropical climate with a wet a ...

Bathurst Class Corvette
The ''Bathurst''-class corvettes were a class of general purpose vessels designed and built in Australia during World War II. Originally classified as minesweepers, but widely referred to as corvettes, the ''Bathurst''-class vessels fulfilled a broad anti-submarine, anti-mine, and convoy escort role. A total of 60 ''Bathurst''-class corvettes were built, at eight Australian shipyards: 36 were paid for by the Australian government and 24 were built on British Admiralty orders. Of these UK-owned vessels, 20 were officially commissioned into the Royal Australian Navy (RAN), and manned by RAN personnel, while four served in the Royal Indian Navy; none of the UK-owned vessels was commissioned into the Royal Navy. An order for three more ''Bathurst''s, to be constructed in India, was cancelled before they were laid down. Although the ''Bathurst''s were designed for the anti-submarine and anti-mine roles, they also served as troop and supply transports, provided air defence for convoy ...

Kangaroo
Kangaroos are four marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms "wallaroo" and "wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size. There are also the tree-kangaroos, another type of macropod, which inhabit the tropical ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
