Limbo (weapon)
Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian–built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s. Operation Limbo was loaded and fired automatically with the crew under-cover and was stabilised in pitch and roll. The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from . The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so t ...

Limbo ASW Mortar On HMNZS Taranaki (F148) C1963
In Catholic theology, Limbo (Latin ''limbus'', edge or boundary, referring to the edge of Hell) is the afterlife condition of those who die in original sin without being assigned to the Hell of the Damned. Medieval theologians of Western Europe described the underworld ("hell", "hades", "infernum") as divided into three distinct parts: Hell of the Damned,''Catholic Encyclopedia'': Hell "However, in the New Testament the term is used more frequently in preference to hades, as a name for the place of punishment of the damned. … held in abomination by the Jews, who, accordingly, used the name of this valley to designate the abode of the damned (Targ. Jon., Gen., iii, 24; Henoch, c. xxvi). And Christ adop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarterdeck
The quarterdeck is a raised deck behind the main mast of a sailing ship. Traditionally it was where the captain commanded his vessel and where the ship's colours were kept. This led to its use as the main ceremonial and reception area on board, and the word is still used to refer to such an area on a ship or even in naval establishments on land. Many such facilities have areas decorated like shipboard quarterdecks. In the 20th century the word came to be applied to the area at the stern of the ship, often (on naval vessels) used for secondary weapons and (on battleships) seaplane catapults. In modern military designs the stern has been roofed over by the helicopter deck but a large space remains underneath which is typically used for sonar equipment or small boats and which is still referred to as the quarterdeck in Commonwealth navies. Ceremonial use There are ancient traditions of offering special deference to the quarterdeck. Greek, Roman, and Carthaginian warships all c ...

Naval Weapons Of The Cold War
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue- ...

Explosive Weapons
An explosive weapon is a weapon that uses high explosive to project blast and/or fragmentation from a point of detonation. In the common practice of states, explosive weapons are generally the preserve of the military, for use in situations of armed conflict, and are rarely used for purposes of domestic policing. When explosive weapons fail to function as designed they are often left as unexploded ordnance (UXO). Classification Explosive weapons may be subdivided by their method of manufacture into explosive ordnance and improvised explosive devices (IEDs). Certain types of explosive ordnance and many improvised explosive devices are sometimes referred to under the generic term bomb. Certain types of explosive weapons may be categorized as light weapons (e.g. grenades, grenade launchers, rocket launchers, anti-tank guided missile launchers, man-portable air-defense systems, and mortars of calibers of less than 100 mm). Many explosive weapons, such as aerial bombs, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Mortars
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
305 Mm Artillery
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Canberra, Australian Capital Territory
Canberra ( ) is the capital city of Australia. Founded following the Federation of Australia, federation of the colonies of Australia as the seat of government for the new nation, it is Australia's largest inland city and the List of cities in Australia by population, eighth-largest city overall. The city is located at the northern end of the Australian Capital Territory at the northern tip of the Australian Alps, the country's highest mountain range. As of June 2021, Canberra's estimated population was 453,558. The area chosen for the capital had been inhabited by Indigenous Australians for up to 21,000 years, with the principal group being the Ngunnawal people. European settlement commenced in the first half of the 19th century, as evidenced by surviving landmarks such as St John the Baptist Church, Reid, St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. Following a long dispute over whether Sydney o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yarralumla, Australian Capital Territory
Yarralumla () is a large inner south suburb of Canberra, the capital city of Australia. Located approximately south-west of the city, Yarralumla extends along the south-west bank of Lake Burley Griffin from Scrivener Dam to Commonwealth Avenue. In 1828, Henry Donnison, a Sydney merchant, was granted a lease on the western side of Stirling Ridge. Donnison's land was named ''Yarralumla'' in a survey of the area conducted in 1834, apparently after the indigenous people's term for the area. It was also spelt ''Yarrolumla'' in other documents. In 1881, the estate was bought by Frederick Campbell, grandson of Robert Campbell who had built a house at nearby Duntroon. Frederick completed the construction of a large, gabled, brick house on his property in 1891 that now serves as the site of Government House, the official residence of the Governor-General of Australia. Campbell's house replaced an elegant, Georgian-style homestead, the main portions of which were erected from local s ... [...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 ...

Rothesay-class Frigate
The ''Rothesay'' class, or Type 12M frigates were a class of frigates serving with the Royal Navy, South African Navy (where they were called President-class frigates) and the Royal New Zealand Navy.Purvis,M.K., 'Post War RN Frigate and Guided Missile Destroyer Design 1944–1969', Transactions, Royal Institution of Naval Architects (RINA), 1974Marriott,Leo, 'Royal Navy Frigates Since 1945', Second Edition, , Published by Ian Allan Ltd (Surrey, UK), 1990 The original Type 12 frigates, the , were designed as first-rate ocean-going convoy escorts in the light of experience gained during World War II. However, such were the capabilities and potential of the design that it was deemed suitable for use as a fast fleet anti-submarine warfare escort. As such, a repeat and improved Type 12 design was prepared, known as the Type 12M (M for "modified") and called the ''Rothesay'' class after the lead ship. A total of twelve vessels were constructed, with the lead ship being laid down in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
