M7 Priest
The 105 mm howitzer motor carriage M7 was an American self-propelled artillery vehicle produced during World War II. It was given the service name 105 mm self propelled, 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 machine-gu ...

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 De ...

Bishop (artillery)
The Bishop, formal designation Ordnance QF 25-pdr on Carrier Valentine 25-pdr Mk 1, was a British self-propelled gun vehicle based on the Valentine tank and armed with the QF 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 vehicle was based on the Valentine II hull, with the turret replaced by a fixed boxy superstructure with large rear doors. It was nicknamed the Bishop for its high mitre-like superstructure. ...

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 self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar (weapon), mortar, or some form of rocket (weapon), rocket/missile launcher. They are usually used for long-range indirect-fire, indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose tank gun, main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-supp ...

Development After the start of World War II, the UK was looking to manufacture complicated parts — notably the crankshafts — of the Rolls-Royce Merlin aircraft engine in the United States, but negotiations with Packard stalled because the company insisted on making complete engines. In June 1940 production drawings arrived in North America and were seized by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright R-975
Wright is an occupational surname originating in England and Scotland. 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 wor ...

M2 Browning Machine Gun
The M2 machine gun or Browning .50-caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It has been used against infantry, light armored vehicles, watercraft, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO countries and has been used by man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M101 Howitzer
The M101A1 (previously designated Howitzer M2A2 on Carriage M2A2) howitzer is an artillery piece developed and used by the United States. It was the standard U.S. light field howitzer in World War II and saw action in both the European and Pacific theaters and during the Korean War. Entering production in 1941, it quickly gained a reputation for accuracy and a powerful punch. The M101A1 fires 105 mm high explosive (HE) semi-fixed ammunition and has a range of or 7 miles, making it suitable for supporting infantry. History Development and designation After World War I, the U.S. Army Ordnance Department studied various captured German 105 mm-caliber howitzers and developed the 105 mm Howitzer M1920 by using the Carriage M1920. A box trail carriage design (the M1925E carriage) and two other split trail designs (the T1 and T2) were also developed, but the original split trail design was found superior after testing. After being selected, the piece was standardized i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Volute Spring Suspension
The vertical volute spring suspension system is a type of vehicle suspension system which uses volute springs to compensate for surface irregularities. This type of the suspension system was mainly fitted on US and Italian tanks and armored fighting vehicles starting from throughout the 1930s up until after the end of the Second World War in 1945. Principle The horizontal arms connected to the road wheels are cranks that drive the vertical arm up and down. The vertical arm connects to the volute spring in the box-shaped area above. Development During the 1930s, many innovations in the components of light tanks would make US tanks considerably more reliable. These included rubber-bushed tracks, rear mounted radial engines and the vertical volute spring suspension. A volute spring is a compression spring in the form of a cone (a volute). Under compression the coils slide over each other, affording a long travel. The result is more stable and powerful than any leaf, coil, ...
