Priest (artillery)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns ( tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Works, Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks-Morse, Fairbanks Morse Engine for their FM, ALCO line. Foundation and early history The company was created in 1901 from the merger of seven smaller locomotive manufacturers with Schenectady Locomotive Works, Schenect ...

Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples of use Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential and suspension. An underbody (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the essential parts of a truck without the body to be ready for operation on the road. A car chassis wi ...

M3 Lee
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US pattern turrets were called "Lee," named after Confederate general Robert E. Lee, while those with British pattern turrets were known as "Grant," named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75mm gun and, coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible. The M3 had considerable firepower and good armor, but had serious drawbacks in its general design and shape, including a high silhouette, an archaic sponson ...

M3 Half-track
The M3 half-track was an American armored personnel carrier half-track widely used by the Allies during World War II and in the Cold War. Derived from the M2 half-track car, the M3 was extensively produced, with about 15,000 standard M3s and more than 38,000 variant units manufactured. The M3 was extensively modified with several dozen variant designs produced for different purposes. During World War II, the M3 and its variants were supplied to the U.S. Army and Marines, as well as British Commonwealth and Soviet Red Army forces, serving on all major fronts throughout the war. The M3 and its variants were produced by many manufacturers including Diamond T, White Motor Company, and Autocar. They were adapted for a wide variety of uses, such as a self-propelled anti-aircraft weapon or self-propelled artillery. Although initially unpopular due to its lack of significant armor or a roof to protect the crew from shrapnel, it was used by most of the Allies during the war. In the Cold ...

T19 Howitzer Motor Carriage
The T19 Howitzer Motor Carriage (HMC) was a howitzer mounted on a M3 Half-track chassis. It saw service during World War II with the U.S. Army. Its secondary armament consisted of an air-cooled M2 machine gun for local defense. It was produced by Diamond T between January 1942 and April 1942. It principally served in the North African Campaign, although some served in the Allied invasion of Sicily and the subsequent Italian Campaign, and even as late as the invasion of southern France in 1944. Specifications The T19 Howitzer Gun Motor Carriage is an artillery purpose M3 Half-track, with a howitzer emplaced on the tracked portion of the frame. It was 20ft 2 in long, 7ft 3.5 in wide, 7ft 8 in high, with a weight of 9.54short tons. The suspension consisted of semi-elliptical longitudinal leaf springs for the wheels and vertical volute springs for the tracks. It was powered by a White 160AX, 147hp, 386 in3, six-cylinder gasoline engine with a compression ratio of 6.3:1. It wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wright R-975
Wright is an occupational surname originating in England. The term 'Wright' comes from the circa 700 AD Old English word 'wryhta' or 'wyrhta', meaning worker or shaper of wood. Later it became any occupational worker (for example, a shipwright is a person who builds ships), and is used as a British family name. The word's use as an occupational title continued until the mid-19th century, often combined with other words such as in shipwright, wheelwright, wainwright and playwright. '', Wright'' was the eleventh most common surname in England. The word ''carpentier'', now "carpenter", was introduced into England in the years after the Norman conquest in 1066 and slowly replaced the traditional name and meaning of wright in most of England. 'Wright' is still used in Scottish English in the original meaning of 'skilled woodworker'. The Incorporation of Wrights of the Trades House of Glasgow, and the Incorporation of Wrights and Masons of Edinburgh Trades retain the word in its o ...
