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.

QF 1-pounder Pom-pom
The QF 1 pounder, universally known as the pom-pom due to the sound of its discharge, was a 37 mm British autocannon, the first of its type in the world. It was used by several countries initially as an infantry gun and later as a light anti-aircraft gun. History Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun. Its longer range necessitated exploding projectiles to judge range, which in turn dictated a shell weight of at least , as that was the lightest exploding shell allowed under the Saint Petersburg Declaration of 1868 and reaffirmed in the Hague Convention of 1899. Early versions were sold under the Maxim-Nordenfelt label, whereas versions in British service (i.e. from 1900) were labelled Vickers, Sons and Maxim (VSM), as Vickers had bought out Maxim-Nordenfelt in 1897 -- but they are the same gun. Service by nation Belgium The Belgian Army used the gun on a high-angle field carriage mounting. Fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Army
The British Army is the principal Army, land warfare force of the United Kingdom. the British Army comprises 73,847 regular full-time personnel, 4,127 Brigade of Gurkhas, Gurkhas, 25,742 Army Reserve (United Kingdom), volunteer reserve personnel and 4,697 "other personnel", for a total of 108,413. The British Army traces back to 1707 and the Acts of Union 1707, formation of the united Kingdom of Great Britain which joined the Kingdoms of Kingdom of England, England and Kingdom of Scotland, Scotland into a Political union, single state and, with that, united the English Army and the Scots Army as the British Army. The Parliament of England, English Bill of Rights 1689 and Convention of the Estates, Scottish Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army.

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Cruisers mounting larger guns and heavier armor relative to most light cruisers would come to be known as heavy cruisers, though the designation of 'light' versus 'heavy' cruisers would vary somewhat between navies. Through their history light cruisers served in a variety of roles, primarily on long-range detached patrol work, covering other military operations or global shipping lanes, as scouts and fleet support vessels for battle fleets, as destroyer command ship ...

Arethusa-class Cruiser (1913)
The ''Arethusa''-class cruisers were a class of eight oil-fired light cruisers of the Royal Navy all ordered in September 1912, primarily for service in the North Sea. They had three funnels with the middle one somewhat larger in diameter than the others. All served in the World War I, First World War. They were found to be very cramped internally. Design and description The earlier scout cruisers were too slow to accomplish their intended duties of working with destroyer flotillas and defending the fleet against attacks by enemy destroyers. The primary emphasis of the ''Arethusa''-class cruisers was a design speed of , to allow them to lead destroyers in combat. In support of this goal, they were the first cruisers to use destroyer-type high-speed steam turbines and oil-fired boilers were chosen to save weight and increase their power to meet the specification. They retained the side protection introduced in the later ships of the previous , but reverted to a mixed main armame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber (artillery)
In artillery, caliber or calibre''Caliber'' is the American English spelling, while ''calibre'' is used in British English. is the internal diameter of a gun barrel, or, by extension, a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove-to-groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land-to-land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land-to-land dimension of the barrel and a copper driving band somewhat larger than ...

Western Front (World War I)
The Western Front was one of the main Theatre (warfare), theatres of war during World War I. Following the outbreak of war in August 1914, the Imperial German Army, German Army opened the Western Front by German invasion of Belgium (1914), invading Luxembourg and Belgium, then gaining military control of important industrial regions in Third Republic of France, France. The German advance was halted with the First Battle of the Marne, Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trench warfare, trenches, stretching from the North Sea to the Swiss frontier with France, the position of which changed little except during early 1917 and again in 1918. Between 1915 and 1917 there were several offensives along this Front (military), front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire, and artillery repeatedly inflicted severe casualties ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maxim Nordenfelt Guns And Ammunition Company
The Maxim-Nordenfelt Guns and Ammunition Company was the result of a takeover by Hiram Maxim of Thorsten Nordenfelt's Nordenfelt Guns and Ammunition Company in 1888. Rothschild issued worth of shares to finance the merger. Nathan Rothschild retained a substantial shareholding in the new Maxim-Nordenfelt combine and ‘exerted a direct influence over its management’. History The company produced a range of light artillery, machine guns and ammunition. It was the subject of one of history's most famous court cases in 1894, Nordenfelt v Maxim, Nordenfelt Guns and Ammunition Co, in which Nordenfelt successfully claimed that the takeover condition preventing him from competing with Maxim for 25 years "in any way" was an unreasonable restraint of trade, but failed to overturn the main condition preventing Nordenfelt from competing with Maxim in the guns and ammunition trade for 25 years. The company competed against the Armstrong subsidiary Elswick Ordnance Company's range of ... [...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, which 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.

Boer
Boers ( ; ; ) are the descendants of the proto Afrikaans-speaking Free Burghers of the eastern Cape frontier in Southern Africa during the 17th, 18th, and 19th centuries. From 1652 to 1795, the Dutch East India Company controlled the Dutch Cape Colony, which the United Kingdom incorporated into the British Empire in 1806. The name of the group is derived from Trekboer then later "boer", which means "farmer" in Dutch and Afrikaans. In addition, the term also applied to those who left the Cape Colony during the 19th century to colonise the Orange Free State, and the Transvaal (together known as the Boer Republics), and to a lesser extent Natal. They emigrated from the Cape to live beyond the reach of the British colonial administration, with their reasons for doing so primarily being the new Anglophone common law system being introduced into the Cape and the British abolition of slavery in 1833. The term ''Afrikaners'' or ''Afrikaans people'' is generally used in moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Boer War
The Second Boer War (, , 11 October 189931 May 1902), also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the two Boer republics (the South African Republic and Orange Free State) over Britain's influence in Southern Africa. The Witwatersrand Gold Rush caused a large influx of "Uitlander, foreigners" (''Uitlanders'') to the South African Republic (SAR), mostly British from the Cape Colony. As they, for fear of a hostile takeover of the SAR, were permitted to vote only after 14 years of residence, they protested to the British authorities in the Cape. Negotiations failed at the botched Bloemfontein Conference in June 1899. The conflict broke out in October after the British government decided to send 10,000 troops to South Africa. With a delay, this provoked a Boer and British ultimatum, and subsequent Boer Irregular military, irregulars and militia attacks on British colonial settlements in Natal ...
