Medium Mark III
The Medium Mark III was a medium tank developed in the United Kingdom during the Interwar period. The prototypes of the Medium Mark II were the three A6 also known as "16-tonner" tanks. From the tests of the A6, three Mark IIIs were built and put into service with the British Army but due to the high cost no more were purchased. Development A6 "Sixteen tonners" In 1926, the British War Office wanted to replace their existing Mark II tanks with a new design. In May the Royal Tank Corps Centre was asked for its opinion, which it submitted in July. One of the requirements was a weight limit of , which led to the nickname "16-tonners". Other specifications included that it could transported by rail, a sufficient supply of lubrication oil to match the range of the tank (dictated by the fuel carried), a wireless set, a gun capable of defeating enemy armour at a range of at least , fuel tanks external to the main compartments and bottom armour sufficient to withstand heavy machi ...

Medium Tank
A medium tank is a classification of tanks, particularly prevalent during World War II which represented a compromise between the mobility oriented light tanks and the armour and armament oriented heavy tanks. A medium tank's classification is not actually based on weight, but off of tactical usage and intended purpose; for instance the German Panzerkampfwagen V Panther medium tank has a mass similar to contemporary Allied heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the German Panzer IV, the Soviet T-34, and the American M4 Sherman) were all medium tank designs. Many of the medium tank lines became what are called main battle tanks in most countries. History The first tanks to carry the name "Medium" appeared in the First World War with the British Medium Mark A Whippet. It was smaller, lighter and faster than the British heavy tanks of the time and only carried machine guns. The medium tank doctrine came into use in the inter ...

Interwar Tanks Of The United Kingdom
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I, and ended with the rise ...

Salisbury Plain
Salisbury Plain is a chalk plateau in the south western part of central southern England covering . It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire. The plain is famous for its rich archaeology, including Stonehenge, one of England's best known landmarks. Large areas are given over to military training and thus the sparsely populated plain is the biggest remaining area of calcareous grassland in northwest Europe. Additionally the plain has arable land, and a few small areas of beech trees and coniferous woodland. Its highest point is Easton Hill. Physical geography The boundaries of Salisbury Plain have never been truly defined, and there is some difference of opinion as to its exact area. The river valleys surrounding it, and other downs and plains beyond them loosely define its boundaries. To the north the scarp of the d ...

Percy Hobart
Major General Sir Percy Cleghorn Stanley Hobart, (14 June 1885 – 19 February 1957), also known as "Hobo", was a British military engineer noted for his command of the 79th Armoured Division during the Second World War. He was responsible for many of the specialised armoured vehicles ("Hobart's Funnies") that took part in the invasion of Normandy and later actions. Early life Hobart was born in Naini Tal, British India, to Robert T. Hobart (of the Indian Civil Service), and Janetta (née Stanley). His mother was born in County Tyrone and lived at Roughan Park, near Newmills, between Cookstown and Dungannon. She married Robert Hobart in Tullaniskin Parish Church, Dungannon, on 7 October 1880. In his youth, Hobart studied history, painting, literature and church architecture. He was educated at Temple Grove School and Clifton College, and in 1904 he graduated from the Royal Military Academy, Woolwich and was commissioned into the Royal Engineers. He was first sent to India, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Mantlet
A gun mantlet is an armour plate or shield attached to an armoured fighting vehicle's gun, protecting the opening through which the weapon's barrel projects from the hull or turret armour and, in many cases, ensuring the vulnerable warhead of a loaded shell does not protrude past the vehicle's armour. On many tanks during World War II, the gun mantlet covered both the main gun and any coaxial armament, and had the thickest armour on the vehicle. However, in many late Cold War and post-Cold War tank designs, the gun mantlet became one of the weaker parts of a vehicle's turret armour and thus a weakness. This was because as many mantlet designs were attached directly to the gun, it drastically increased the weight of the whole gun system and the amount of effort needed to elevate and depress it. This was an issue for gun stabilizers as they proved to be less efficient and accurate in keeping the gun steady with the added weight of the mantlet. Therefore, as seen in tanks such a ...

REME
The Corps of Royal Electrical and Mechanical Engineers (REME ) is a corps of the British Army that maintains the equipment that the Army uses. The corps is described as the "British Army's Professional Engineers". History Prior to REME's formation, maintenance was the responsibility of several different corps: * Royal Army Ordnance Corps—weapons and armoured vehicles * Royal Engineers—engineering plant and machinery, and RE motor transport * Royal Corps of Signals—communications equipment * Royal Army Service Corps—other motor transport * Royal Artillery—heavy weapons artificers During World War II, the increase in quantity and complexity of equipment exposed the flaws in this system. Pursuant to the recommendation of a Committee on Skilled Men in the Services chaired by William Beveridge, the Corps of Royal Electrical and Mechanical Engineers was formed on 1 October 1942. Phase I Such a major re-organisation was too complex to be carried out quickly and complet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolls-Royce Phantom I
The Rolls-Royce Phantom was Rolls-Royce's replacement for the original Silver Ghost. Introduced as the New Phantom in 1925, the Phantom had a larger engine than the Silver Ghost and used pushrod-operated overhead valves instead of the Silver Ghost's side valves. The Phantom was built in Derby, England, and Springfield, Massachusetts, in the United States. There were several differences in specification between the English and American Phantoms. The Phantom was replaced by the Phantom II in 1929. The designation Phantom I was never used by Rolls-Royce; it is a construct of enthusiasts applied to help distinguish it from other generations with the same model name. Description Name Introduced in 1925, the New Phantom was Rolls-Royce's second 40/50 hp model. To differentiate between the 40/50 hp models, Rolls-Royce named the new model "New Phantom" and renamed the old model "Silver Ghost", which was the name given to their demonstration example, Registration ...
