QF 13-pounder 6 Cwt AA Gun
The Ordnance QF 13 pounder Mk III anti-aircraft gun, also known as 13 pounder 6 cwt, was an early British improvisation in World War I to adapt the QF 13-pounder field gun to anti-aircraft use. 6 cwt referred to the weight of barrel and breech (6 × 112 lb = 672 lb) to differentiate it from other "13 pounder" guns. History This was a standard QF 13 pounder field gun barrel and breech with the addition of a retaining catch to the breech to retain the round when loading at high angles. It was first approved in October 1914 and was issued on Mk I high angle mounting, usually mounted on a motor lorry. The Mk I mounting had an additional recuperator housing mounted directly above the normal recuperator to facilitate gun runout at high angles. Hence the appearance was of a gun barrel with 2 slightly shorter tubes of similar diameter above it. Mk II mount improved the usability, added deflection gear and the recoil system was improved so that the additional recupe ...

Thornycroft J Type
The Thornycroft J Type was a British truck built by the Thornycroft company, it saw widespread service with the British military and Imperial forces during the First World War. Design The J Type was a 3-ton 4x2 truck, it was powered by a Thornycroft M4 four-cylinder inline 6,256 cc side-valve petrol engine that developed at 1,800 rpm, it drove the rear wheels through a four-speed gearbox. History The J Type was designed by Thornycroft to meet a 1911 War Office specification for a 3-ton " subsidy scheme" cargo truck, the scheme provided a grant of £110 to civilian companies towards the purchase price of trucks suitable for military service, but included a provision that the military could requisition the vehicles if they required them. Initially the War Office purchased H, J and K Type chassis from Thornycroft, the first 24 being delivered August 1912 and May 1913 with further deliveries of all three type to follow, but in August 1914 the War Office settled on the J Type chass ...

QF 3 Inch 20 Cwt
The QF 3 inch 20 cwt anti-aircraft gun became the standard anti-aircraft gun used in the home defence of the United Kingdom against German airships and bombers and on the Western Front in World War I. It was also common on British warships in World War I and submarines in World War II. 20 cwt referred to the weight of the barrel and breech, to differentiate it from other 3 inch guns (1cwt = 1 hundredweight = , hence the barrel and breech together weighed ). While other AA guns also had a bore of , the term ''3 inch'' was only ever used to identify this gun in the World War I era, and hence this is what writers are usually referring to by ''3 inch AA gun''. Design and development The gun was based on a prewar Vickers naval QF gun with modifications specified by the War Office in 1914. These (Mk I) included the introduction of a vertical sliding breech-block to allow semi-automatic operation. When the gun recoiled and ran forward after firing, the motion also opened the bree ...

World War I Artillery Of The United Kingdom
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

List Of Anti-aircraft Guns ...
Anti-aircraft guns are weapons designed to attack aircraft. Such weapons commonly have a high rate of fire and are able to fire shells designed to damage aircraft. They also are capable of firing at high angles, but are also usually able to hit ground targets as well in a direct fire role.

QF 4-inch Naval Gun Mk V
The QF 4 inch Mk V gunMk V = Mark 5. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Mark V indicates this was the fifth model of QF 4-inch gun. was a Royal Navy gun of World War I which was adapted on HA (i.e. high-angle) mountings to the heavy anti-aircraft role both at sea and on land, and was also used as a coast defence gun. Service Naval service This QF gun was introduced to provide a higher rate of fire than the BL 4 inch Mk VII. It first appeared in 1914 as secondary armament on s, was soon adapted to a high-angle anti-aircraft role. It was typically used on cruisers and heavier ships, although s of 1917 also mounted the gun. Mk V was superseded by the QF 4 inch Mk XVI as the HA (i.e. anti-aircraft) gun on new warships in the 1930s, but it continued to serve on many ships such as destroyers, light and heavy cruisers in World War II.

QF 12-pounder 12 Cwt AA Gun
The 12 pounder 12 cwt anti-aircraft gun was borrowed for AA use from the QF 12 pounder 12 cwt coast defence gun with the addition of a modified cradle for higher elevation, a retaining catch for the cartridge, and an additional spring recuperator above the barrel and high-angle sights. Writers commonly refer to it simply as "12 pounder anti-aircraft gun". 12 cwt referred to the weight of the barrel and breech (12 x = ) to differentiate it from other "12 pounder" guns. History When World War I began Britain had no anti-aircraft artillery and had given little thought to it. Hence in 1914 when Germany occupied parts of Belgium and northern France, it faced the risk of air attack, and various medium calibre guns were adapted to high-angle mountings, including the 12 pdr 12 cwt. All QF 12 pounder ammunition at the time was "Separate loading QF" i.e. the propellant came in a brass cartridge case with primer ready installed, but the shell was loaded separately.

QF 13-pounder 9 Cwt
The 13 pounder 9 cwt anti-aircraft gunIn the name, 13 pounder referred to the approximate weight of the standard shell, and 9 cwt referred to the weight of the barrel and breech (9 × 112 lb = 1008 lb), to differentiate it from other varieties of "13 pounder". became the standard mobile British anti-aircraft gun of the World War I era, especially in theatres outside Britain. History Earlier anti-aircraft guns based on 13 pounder and 18 pounder guns proved unsatisfactory, primarily due to their low muzzle velocities. On 18 February 1915 Sir John French, commander of the British Expeditionary Force in France, asked for an anti-aircraft gun with a muzzle velocity of . On 19 August 1915 the Army Council proposed adapting existing 18-pounder guns (3.3-inch bore) to use 13-pounder (3-inch) shells, thus meeting the requirement for higher velocity. This weapon combined an 18 pounder breech and barrel with a liner (sleeve) inserted to reduce the bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Front (World War I)
The Western Front was one of the main theatres of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918. Between 1915 and 1917 there were several offensives along this front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made. Among the most costly of these offensives were the Battle of Verdun, in 1916, with a combined 700,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macedonian Front (World War I)
The Macedonian front, also known as the Salonica front (after Thessaloniki), was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the autumn of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and in insufficient force to prevent the fall of Serbia, and was complicated by the internal political crisis in Greece (the "National Schism"). Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian Army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian front remained quite stable, despite local actions, until the great Allied offensive in September 1918, which resulted in the capitulation of Bulgaria and the liberation of Serbia.

Mesopotamian Campaign
The Mesopotamian campaign was a campaign in the Middle Eastern theatre of World War I fought between the Allies represented by the British Empire, troops from Britain, Australia and the vast majority from British India, against the Central Powers, mostly the Ottoman Empire. Background The Ottoman Empire had conquered the region in the early 16th century, but never gained complete control. Regional pockets of Ottoman control through local proxy rulers maintained the Ottomans' reach throughout Mesopotamia (modern Iraq). With the turn of the 19th century came reforms. Work began on a Baghdad Railway in 1888; by 1915 it had only four gaps, and travel time from Istanbul to Baghdad had fallen to 21 days. The Anglo-Persian Oil Company (APOC) had obtained exclusive rights to petroleum deposits throughout the Persian Empire, except in the provinces of Azerbaijan, Ghilan, Mazendaran, Asdrabad, and Khorasan.The Encyclopedia Americana, 1920, v.28, p.403 In 1914, months before the war bega ...
