HMS Antrim (1903)
HMS ''Antrim'' was a armoured cruiser built for the Royal Navy in the first decade of the 20th century. She was assigned to the 1st Cruiser Squadron of the Channel Fleet upon completion in 1905 and was transferred to the 2nd Cruiser Squadron (United Kingdom), 2nd Cruiser Squadron of the Atlantic Fleet (United Kingdom), Atlantic Fleet in 1907. She was assigned to the Reserve fleet, reserve Third Fleet in 1909 and then became flagship of the 3rd Cruiser Squadron (United Kingdom), 3rd Cruiser Squadron of the reserve Second Fleet in 1913. Upon mobilisation in mid-1914 her squadron was assigned to the Grand Fleet and spent much of its time patrolling the northern exits from the North Sea. ''Antrim'' was sent to Arkhangelsk in mid-1916 and then to the North America and West Indies Station for convoy escort duties. She was Ship decommissioning, paid off at the end of 1917, but was Ship commissioning, recommissioned in mid-1918 as a convoy escort. The ship was in reserve by 1919, b ...

Naval Gun
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for naval gunfire support, shore bombardment and anti-aircraft roles. The term generally refers to tube-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire, fire-throwers. From the late Middle Ages onwards, warships began to carry cannon, cannons of various calibres. The Mongol invasion of Java introduced cannons to be used in naval warfare (e.g. Cetbang by the Majapahit). The Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacturer, aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce Holdings, Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Platforms & Services, BAE Systems Land Systems.

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treatise On Ammunition
''Treatise on Ammunition'', from 1926 retitled ''Text Book of Ammunition'', is a series of manuals detailing all British Empire military and naval service ammunition and associated equipment in use at the date of publication. It was published by the War Office at approximate 5 year intervals. As the guns are listed for which the ammunition can be used, the Treatise also constitutes a list of guns in service at the publication date. Its predecessor was ''Ammunition: A Descriptive Treatise on the Different Projectiles, Charges, Fuzes, Rockets, &c., at Present in Use for Land and Sea Service, and on Other War Stores Manufactured in the Royal Laboratory'' of 1867. The editions contain diagrams, measurements, storage and transportation instructions useful to officers involved in storage, transport and firing of ammunition. It is an important primary source of information for military historians researching the types and capabilities of ammunition available to the British military at th ...

Welin Breech Block
The Welin breech block was a revolutionary stepped, interrupted thread design for locking artillery breeches, invented by Axel Welin in 1889 or 1890. Shortly after, Vickers acquired the British patents. Welin breech blocks provide obturation for artillery pieces which use separate loading bagged charges and projectiles. In this system the projectile is loaded first and then followed by cloth bags of propellant. Design The breech block screw incorporates multiple threaded "steppings" of progressively larger radius and a gap step occupying each circular section. A three step breech block screw's circular area would nominally be divided into quarters, with each quarter containing three threaded sections of progressively increasing height and a gap step for insertion. Each step engages with its matching thread cut in the gun breech when inserted and rotated. A gap in the thread steps was still necessary for the insertion of the largest step before rotation, so the area of the br ...

British Ordnance Terms
This article explains terms used for the British Armed Forces' ordnance (i.e.: weapons) and also ammunition. The terms may have slightly different meanings in the military of other countries. BD Between decks: applies to a naval gun mounting in which part of the rotating mass is below the deck, and part of it is above the deck. This allows for a lower profile of turret, meaning that turrets need not be superfiring (i.e. they can be mounted on the same deck and not obstruct each other at high angles of elevation.) BL The term BL, in its general sense, stood for breech loading, and contrasted with muzzle loading. The shell was loaded via the breech (i.e. the gunner's end of the barrel, which opened) followed by the propellant charge, and the breech mechanism was closed to seal the chamber. Breech loading, in its formal British ordnance sense, served to identify the gun as the type of rifled breechloading gun for which the powder charge was loaded in a silk or cloth bag and the br ...

Devonshire Class Cruiser (1903)
The ''Devonshire''-class cruiser was a group of six armoured cruisers built for the Royal Navy in the first decade of the 20th century. All ships of the class served in World War I. ''Argyll'' was wrecked, and ''Hampshire'' was sunk by a naval mine. The four survivors were disposed of soon after the war. Design and description The ''Devonshire'' class was designed as improved versions of the preceding and were also intended for commerce protection. The armament of the new design was made more powerful by the replacement of the twin six-inch (152 mm) turrets and the forward double six-inch casemates by four 7.5-inch (190 mm) single turrets in a diamond arrangement. The ships were designed to displace . They had an overall length of , a beam of and a deep draught of . The ''Devonshire''-class ships were powered by two 4-cylinder triple-expansion steam engines, each driving one shaft, which produced a total of and gave a maximum speed of . The engines were powered by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
