HMS Achates (1912)
HMS ''Achates'' was an (or K)-class destroyer of the British Royal Navy. She was built by the Scottish shipbuilder John Brown and was built between 1912 and 1913. Like all ''Acasta''-class destroyers, ''Achates'' was armed with three guns and two torpedo tubes, with a specified speed of . ''Achates'' served throughout the First World War, serving with the Grand Fleet in the early years of the war, and taking part in the Battle of Jutland in 1916. Later in the war she served as a convoy escort. She was sold for Ship breaking, scrapping in 1921. Design and construction Under the 1911–1912 shipbuilding programme for the Royal Navy, the British Admiralty ordered 20 s, with 12 to the standard Admiralty design and 8 more builder's specials, with detailed design left to the builders. The Scottish shipbuilder John Brown & Company received an order for three ''Acasta''s (, ''Achates'' and ) under the programme, all to be built to the standard Admiralty design. The ''Acasta''s were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Brown & Company
John Brown and Company of Clydebank was a Scottish Naval architecture, marine engineering and shipbuilding firm. It built many notable and world-famous ships including , , , , , and ''Queen Elizabeth 2 (ship), Queen Elizabeth 2''. At its height, from 1900 to the 1950s, it was one of the most highly regarded, and internationally famous, shipbuilding companies in the world. However thereafter, along with other UK shipbuilders, John Brown's found it increasingly difficult to compete with the emerging shipyards in Eastern Europe and the far East. In 1968 John Brown's merged with other Clydeside shipyards to form the Upper Clyde Shipbuilders consortium, but that collapsed in 1971. The company then withdrew from shipbuilding but its engineering arm remained successful in the manufacture of industrial gas turbines. In 1986 it became a wholly owned subsidiary of Trafalgar House (company), Trafalgar House, which in 1996 was taken over by Kvaerner. The latter closed the Clydebank engine ...

Yarrow Boiler
Yarrow boilers are an important class of high-pressure water-tube boilers. They were developed by Yarrow Shipbuilders, Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships. The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them. A single steam drum is mounted at the top between them, with smaller water drums at the base of each bank. Circulation, both upwards and downwards, occurs within this same tube bank. The Yarrow's distinctive features were the use of straight tubes and also circulation in both directions taking place within the tube bank, rather than using external downcomers. Early watertube boilers Early use of the water-tube boiler within the Royal Navy was controversial at times, giving rise to the '' 'Battle of the Boilers' '' around 1900. These first boilers, such as the Belleville boiler, Belleville ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Lord Of The Admiralty
First Lord of the Admiralty, or formally the Office of the First Lord of the Admiralty, was the title of the political head of the English and later British Royal Navy. He was the government's senior adviser on all naval affairs, responsible for the direction and control of the Admiralty, and also of general administration of the Naval Service of the Kingdom of England, Great Britain in the 18th century, and then the United Kingdom, including the Royal Navy, the Royal Marines, and other services. It was one of the earliest known permanent government posts. Apart from being the political head of the Naval Service the post holder was simultaneously the pre-eminent member of the Board of Admiralty. The office of First Lord of the Admiralty existed from 1628 until it was abolished when the Admiralty, Air Ministry, Ministry of Defence and War Office were all merged to form the new Ministry of Defence in 1964. Its modern-day equivalent is the Secretary of State for Defence. Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winston Churchill

Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

Yard Number
The yard (symbol: yd) is an English unit of length in both the British imperial and US customary systems of measurement equalling 3 feet or 36 inches. Since 1959 it has been by international agreement standardized as exactly 0.9144 meter. A distance of 1,760 yards is equal to 1 mile. The theoretical US survey yard is very slightly longer. Name The term, ''yard'' derives from the Old English , etc., which was used for branches, staves and measuring rods. It is first attested in the late 7th century laws of Ine of Wessex, wherein the "yard of land" mentioned is the yardland, an old English unit of tax assessment equal to hide. Around the same time the Lindisfarne Gospels account of the messengers from John the Baptist in the Gospel of Matthew used it for a branch swayed by the wind. In addition to the yardland, Old and Middle English both used their forms of "yard" to denote the surveying lengths of or , used in computing acres, a distance ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

Aeneid
The ''Aeneid'' ( ; or ) is a Latin Epic poetry, epic poem that tells the legendary story of Aeneas, a Troy, Trojan who fled the Trojan War#Sack of Troy, fall of Troy and travelled to Italy, where he became the ancestor of the Ancient Rome, Romans. Written by the Roman poet Virgil between 29 and 19 BC, the ''Aeneid'' comprises 9,896 lines in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas' wanderings from Troy to Italy, and the poem's second half tells of the Trojans' ultimately victorious war upon the Latins (Italic tribe), Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed. The hero Aeneas was already known to Greco-Roman legend and myth, having been a character in the ''Iliad''. Virgil took the disconnected tales of Aeneas' wanderings, his vague association with the foundation of Ancient Rome, Rome and his description as a personage of no fixed characteristics other than a scrupulous ''pietas'', ...

Aeneas
In Greco-Roman mythology, Aeneas ( , ; from ) was a Troy, Trojan hero, the son of the Trojan prince Anchises and the Greek goddess Aphrodite (equivalent to the Roman Venus (mythology), Venus). His father was a first cousin of King Priam of Troy (both being grandsons of Ilus (son of Tros), Ilus, founder of Troy), making Aeneas a second cousin to Priam's List of children of Priam, children (such as Hector and Paris (mythology), Paris). He is a minor character in Greek mythology and is mentioned in Homer's ''Iliad''. Aeneas receives full treatment in Roman mythology, most extensively in Virgil's ''Aeneid'', where he is cast as an ancestor of Romulus and Remus. He became the first true hero of Rome. Snorri Sturluson identifies him with the Norse god Víðarr of the Æsir.The Prose Edda of Snorri Sturlson Translated by Arthur Gilchrist Brodeur [1916] Prologue II at Internet Sacred Texts Archive.

Achates (Aeneid)
In the ''Aeneid'', Achates (Ancient Greek: Ἀχάτης, "good, faithful Achates", ''fidus Achates'' as he was called) was a close friend of Aeneas; his name became a by-word for a very intimate companion. Mythology Achates accompanied Aeneas throughout his adventures, reaching Carthage with him in disguise when the pair were scouting the area, and leading him to the Sibyl of Cumae. Virgil represents him as remarkable for his fidelity, and a perennial type of that virtue. However, despite being Aeneas's most important Trojan, he is notable for his lack of character development. In fact, he has only four spoken lines in the entire epic. Aeneas, surrounded by only a shadowy cast of allies, is thus emphasised as the lone protagonist and at the same time cut off from help on his quest.

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), 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, duri ...

QF 2-pounder Naval Gun
The 2-pounder gun, officially the QF 2-pounder ( QF denoting "quick firing") and universally known as the pom-pom, was a British autocannon, used as an anti-aircraft gun by the Royal Navy.British military of the period traditionally denoted smaller guns in terms of the approximate weight of the standard projectile, rather than by its bore diameter, which in this case was 40 mm. References to 40-mm anti-aircraft guns invariably mean the Bofors gun, while references to 2-pounder anti-aircraft guns mean this gun. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired , projectiles. Predecessors – Boer War and the Great War QF 1 pounder The first gun to be called a pom-pom was the 37 mm Nordenfelt-Maxim or "QF 1-pounder" introduced during the Second Boer War, the smallest artillery piece of that war.
