Bishop (artillery)
The Bishop was a British self-propelled gun vehicle based on the Valentine tank and armed with the 25 pounder gun-howitzer, which could fire an HE shell or an armour-piercing shell. A result of a rushed attempt to create a self-propelled gun, the vehicle had numerous problems, was produced in limited numbers and was soon replaced by better designs. Design and development The rapid manoeuvre warfare practiced in the North African Campaign led to a requirement for a self-propelled artillery vehicle armed with the 25-pounder gun-howitzer. In June 1941, the development was entrusted to the Birmingham Railway Carriage and Wagon Company. A prototype was ready for trials by August and ordered by November 1941.''The complete guide to tanks and armoured fighting vehicles'', p 312, The result was a vehicle with the formal title: "Ordnance QF 25-pdr on Carrier Valentine 25-pdr Mk 1". The vehicle was based on the Valentine II hull, with the turret replaced by a fixed boxy superstru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Desert (North Africa)
The Western Desert of Egypt is an area of the Sahara that lies west of the river Nile, up to the Libyan border, and south from the Mediterranean Sea to the border with Sudan. It is named in contrast to the Eastern Desert which extends east from the Nile to the Red Sea. The Western Desert is mostly rocky desert, though an area of sandy desert, known as the Great Sand Sea, lies to the west against the Libyan border. The desert covers an area of which is two-thirds of the land area of the country. Its highest elevation is in the Gilf Kebir plateau to the far south-west of the country, on the Egypt-Sudan-Libya border. The Western Desert is barren and uninhabited save for a chain of oases which extend in an arc from Siwa, in the north-west, to Kharga in the south. It has been the scene of conflict in modern times, particularly during the Second World War. Administratively the Western Desert is divided between various governorates; in the north and west, the Matrouh Governorate adm ...

Mitre
The mitre (Commonwealth English) (; Greek: μίτρα, "headband" or "turban") or miter (American English; see spelling differences), is a type of headgear now known as the traditional, ceremonial headdress of bishops and certain abbots in traditional Christianity. Mitres are worn in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Churches, the Anglican Communion, some Lutheran churches, for important ceremonies, by the Metropolitan of the Malankara Mar Thoma Syrian Church, and also, in the Catholic Church, all cardinals, whether or not bishops, and some Eastern Orthodox archpriests. Etymology μίτρα, ''mítra'' ( Ionic μίτρη, ''mítrē'') is Greek, and means a piece of armour, usually a metal guard worn around the waist and under a cuirass, as mentioned in Homer's Iliad. In later poems, it was used to refer to a headband used by women for their hair; and a sort of formal Babylonian headdress, as mentioned by Herodotus ('' Histories'' 1.195 and 7.90 ...

World War II Self-propelled Artillery
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] |
AS-90
The AS-90 ("Artillery System for the 1990s"), known officially as Gun Equipment 155 mm L131, is an armoured self-propelled artillery weapon used by the British Army. It can fire standard charges up to using 39 calibre long barrel (comparable to Russian 2S19 Msta) and with 52 cal. one. The max. rate of fire is 3 rounds in 10 seconds (burst), 6 per minute for 3 minutes (intense), and 2/min. for 60 minutes (sustained). History AS-90 was designed and built by the Armaments division of Vickers Shipbuilding and Engineering (VSEL). Between 1992 and 1995, VSEL supplied 179 vehicles at a cost of £300 million ( $480 million). The AS-90 was first deployed by the British Army in 1993. The AS-90s were acquired to re-equip six of the eight self-propelled field artillery regiments (each of 24 guns) in the I (BR) Corps, replacing the 105 mm FV433 Abbot SPG and older M109 155 mm Self Propelled Gun and FH70 towed howitzer. In 1999, VSEL became a part of BAE Systems. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FV433 Abbot
FV433, 105mm, Field Artillery, Self-Propelled "Abbot" is the self-propelled artillery, or more specifically self-propelled gun (SPG), variant of the British Army FV430 series of armoured fighting vehicles (AFVs), using much of the chassis of the FV430 but with a fully rotating turret at the rear housing the 105 mm gun and given the vehicle designation of FV433. Designed as a Sexton replacement, its correct designation was "Gun Equipment 105mm L109 (Abbot)". "L109" was little used, probably to avoid confusion with the 155 mm M109 howitzer that entered UK service at about the same time. The name "Abbot" continued the Second World War style of naming self-propelled artillery after ecclesiastical titles. The FV433 used a different configuration of power pack from other vehicles in the FV430 series. Development Ammunition A completely new ammunition family, comprising shells, fuzes and cartridges, was designed for Abbot's L13 gun, designated "105 mm Field" ("105 mm ...

Deacon (artillery)
The AEC Mk I Gun Carrier, known as Deacon, was a British armoured fighting vehicle of the Second World War. It was an attempt to make the QF 6 pounder anti-tank gun into a self-propelled artillery piece. It was employed only during the North African Campaign from 1942 to 1943. History The Deacon was developed in 1942 to provide British Army units in North Africa with a mobile anti-tank weapon. It can be seen as a development of the practice of carrying smaller artillery pieces '' en portee'' (sitting on the back of trucks). This meant that the artillery could quickly move albeit with some loss of traverse. The basis of the Deacon Gun Carrier was an AEC Matador truck chassis. A 6-pounder gun with enclosed armoured shield was mounted on the flat bed at the rear of the chassis. The gunner and loader operated the gun from behind the shield. The conventional cab was replaced with a boxy armoured construction that covered the engine and the driver's position. Production started in Dec ...

105 Millimeter Howitzer Motor Carriage M7
The 105 mm Howitzer Motor Carriage M7 was an American self-propelled gun vehicle produced during World War II. It was given the official service name 105 mm Self Propelled Gun, Priest by the British Army, due to the pulpit-like machine gun ring, and following on from the Bishop and the contemporary Deacon self-propelled guns. Design and development During the early stages of World War II, US Army observers realized that they would need a self-propelled artillery vehicle with sufficient firepower to support armored operations. Lessons learned with half-tracks (such as the T19 Howitzer Motor Carriage (HMC) with a 105 mm howitzer on the M3 Half-track chassis) also showed that this vehicle would have to be armored and fully tracked. It was decided to use the M3 Lee chassis as the basis for this new vehicle design, named T32.Bishop, p. 120. The pilot vehicles used the M3 chassis with an open-topped superstructure, mounting an M2A1 105 mm howitzer, with a machin ...

Ordnance QF 25-pounder
The Ordnance QF 25-pounder, or more simply 25-pounder or 25-pdr, was the major British field gun and howitzer during the Second World War. Its calibre is 3.45-inch (87.6 mm). It was introduced into service just before the war started, combining both high-angle and direct-fire abilities, a relatively high rate of fire, and a reasonably lethal shell in a highly mobile piece. It remained the British Army's primary artillery field piece well into the 1960s, with smaller numbers serving in training units until the 1980s. Many Commonwealth of Nations countries used theirs in active or reserve service until about the 1970s and ammunition for the weapon is currently being produced by Pakistan Ordnance Factories. Initial production was slow, but by 1945, over 12,000 had been manufactured. The 25-pounder was probably the most outstanding field artillery piece used by British and Commonwealth forces in the Second World War, being durable, easy to operate and versatile.

Sexton (artillery)
The 25pdr SP, tracked, Sexton was a Canadian-designed self-propelled artillery vehicle of the Second World War. It was based on Canadian-built derivatives of the American M3 Lee and M4 Sherman tank chassis. Canada had set up to produce the Ram tank using the M3 chassis and Grizzly (a copy of the M4) to complement US medium tank production; when Sherman production in the US expanded and supply was no longer a problem, it was decided in 1943 to switch the Canadian production lines to produce the Sexton to give the British Army a mobile artillery gun using their Ordnance QF 25-pounder gun-howitzer for commonality with towed guns. The Sexton could fire either HE shell or an armour-piercing shell. It found use in the Canadian and British Army, as well as numerous other British Empire and associated forces. Just after the war, a number of Grizzly and Sextons were sold to Portugal, who used them into the 1980s. History In order to better provide artillery support in the highly mobile ...
