HMAS Pirie (J189)
HMAS ''Pirie'' (J189/B249/A123), named for the city of Port Pirie, was one of 60 ''Bathurst''-class corvettes constructed during World War II and one of 20 built on Admiralty order but manned by personnel of and commissioned into the Royal Australian Navy (RAN). Early in her career, ''Pirie'' operated as an escort in the South West Pacific Area, and in April 1943, was damaged off Oro Bay by Japanese aircraft. Tensions between the corvette's commanding officer and the rest of the ship's company, excaberated by the lack of leave, mail, and pay, boiled over during the repair period, and led to a strike-like mutiny by the junior sailors shortly after ''Pirie'' returned to service. The mutiny was poorly handled, and the commander was replaced at the end of 1943. During 1944, the ship continued to operate as a convoy escort, and undertook minesweeping duties until she was attached to the British Pacific Fleet. ''Pirie'' was the third RAN ship to enter Japanese waters, and was pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMAS Pire (AWM P01185-005)
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 deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike Action
Strike action, also called labor strike, labour strike, or simply strike, is a work stoppage caused by the mass refusal of employees to Labor (economics), work. A strike usually takes place in response to grievance (labour), employee grievances. Strikes became common during the Industrial Revolution, when Labour economics, mass labor became important in factories and mines. As striking became a more common practice, governments were often pushed to act (either by private business or by union workers). When government intervention occurred, it was rarely neutral or amicable. Early strikes were often deemed unlawful conspiracies or anti-competitive cartel action and many were subject to massive legal repression by state police, federal military power, and federal courts. Many Western nations legalized striking under certain conditions in the late 19th and early 20th centuries. Strikes are sometimes used to pressure governments to change policies. Occasionally, strikes destabilize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milne Bay
Milne Bay is a large bay in Milne Bay Province, south-eastern Papua New Guinea. More than long and over wide, Milne Bay is a sheltered deep-water harbor accessible via Ward Hunt Strait. It is surrounded by the heavily wooded Stirling Range to the north and south, and on the northern shore, a narrow coastal strip, soggy with sago and mangrove swamps. The bay is named after Sir Alexander Milne. History * Surveyed by Luis Vaez de Torres in July 1606. * Surveyed by Captain Owen Stanley, R.N. F.R.S. in 1850. World War II During World War II, the area was the site of the Battle of Milne Bay in 1942 and by late 1943 it became the major support base, Naval Base Milne Bay, for the New Guinea campaign through the development of Finschhafen as an advanced base after that area was secured in the Huon Peninsula campaign. By January 1944 about 140 vessels were in harbor due to congestion at the facilities. Congestion was relieved by opening of a port at Finschhafen and extensive improveme ...

Bofors 40 mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 ...
