HMAS Ipswich (J186)
HMAS ''Ipswich'' (J186/B244/A118), named for the city of Ipswich, Queensland, was one of 60 s built during World War II and one of 20 built on Admiralty order but manned by personnel of and later commissioned into the Royal Australian Navy (RAN). ''Ipswich'' was later operated by the Royal Netherlands Navy (RNLN) as HNLMS ''Morotai'', and by the Indonesian Navy (TNI-AL) as KRI ''Hang Tuah''. In Indonesian service in 1958 the ship was attacked by a CIA aircraft and sunk with considerable loss of life. Design and construction In 1938, the Australian Commonwealth Naval Board (ACNB) identified the need for a general purpose 'local defence vessel' capable of both anti-submarine and mine-warfare duties, while easy to construct and operate.Stevens, ''The Australian Corvettes'', p. 1Stevens, ''A Critical Vulnerability'', p. 103 The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least , and a range of Stevens, ''A Critical Vulnerabili ...

Ipswich, Queensland
Ipswich () is a city in South East Queensland, Australia. Situated on the Bremer River, it is approximately west of the Brisbane central business district. The city is renowned for its architectural, natural and cultural heritage. Ipswich preserves and operates from many of its historical buildings, with more than 6000 heritage-listed sites and over 500 parks. Ipswich began in 1827 as a mining settlement. History Early history Ipswich according to The Queenslander (Brisbane, Qld,: 1866-1939), Thursday 18 January 1934, Page 13 was tribally known as Coodjirar meaning place of the Red Stemmed Gum Tree in the Yugararpul language. Jagara (also known as Jagera, Yagara, and Yuggara) and Yugarabul (also known as Ugarapul and Yuggerabul) are Australian Aboriginal languages of South-East Queensland. There is some uncertainty over the status of Jagara as a language, dialect or perhaps a group or clan within the local government boundaries of Ipswich City Council, Lockyer Regional C ...

Kalimantan
Kalimantan () is the Indonesian portion of the island of Borneo. It constitutes 73% of the island's area. The non-Indonesian parts of Borneo are Brunei and East Malaysia. In Indonesia, "Kalimantan" refers to the whole island of Borneo. In 2019, President of Indonesia Joko Widodo proposed that Capital of Indonesia, Indonesia's capital be moved to Kalimantan, and in January 2022 Indonesian legislature approved the proposal. The shift is expected to take up to 10 years. Etymology The name ''Kalimantan'' is derived from the Sanskrit word ''Kalamanthana'', which means "burning weather island", or island with a very hot temperature, referring to its hot and humid tropical climate. It consists of the two words ''Kāla (time), kal[a]'' ("time, season, period") and ''manthan[a]'' ("boiling, churning, burning"). The indigenous people of the eastern region of Borneo referred to their island as ''Pulu K'lemantan'' or "Kalimantan" when the sixteenth century Portuguese explorer Jorge de Meneze ...

Minister For Home Affairs (Australia)
The Minister for Home Affairs in the Government of Australia is the minister responsible for the Department of Home Affairs, the country's interior ministry. The current minister is Clare O'Neil of the Labor Party, who has held the position since 1 June 2022 in the Albanese ministry. The current Department of Home Affairs was created in December 2017. The first department with that name was created in 1901, as one of the original six departments created at Federation, and was responsible for a wide range of areas not captured by the other departments. Similar departments have existed in almost all subsequent governments, under several different names. The specific title "Minister for Home Affairs" has been created six times – in 1901, 1929, 1977, 1987, 2007 and 2017.

Royal Indian Navy
The Royal Indian Navy (RIN) was the naval force of British India and the Dominion of India. Along with the Presidency armies, later the Indian Army, and from 1932 the Royal Indian Air Force, it was one of the Armed Forces of British India. From its origins in 1612 as the East India Company's Marine, the Navy underwent various changes, including changes to its name. Over time it was named the Bombay Marine (1686), the Bombay Marine Corps (1829), the Indian Navy (1830), Her Majesty's Indian Navy (1858), the Bombay and Bengal Marine (1863), the Indian Defence Force (1871), Her Majesty's Indian Marine (1877) and the Royal Indian Marine (1892). It was finally named the Royal Indian Navy in 1934. However, it remained a relatively small force until the Second World War, when it was greatly expanded. After the partition of India into two independent states in 1947, the Navy was split between Pakistan and India. One-third of the assets and personnel were assigned to Royal Pakistan Nav ...

Sloop-of-war
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy. Rigging A sloop-of-war was quite different from a civilian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

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 ...

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 ...

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. Secondary na ...
