Orange William
Orange William was a British project to develop a long-range anti-tank missile as a possible alternative to the Malkara being developed in Australia. The project was drawn up in 1954 and the resulting contract won by Fairey Engineering in 1956. It was very similar to Malkara in form and layout, including the Malkara's distinctive square fuselage. It differed primarily in its guidance system (semi-automatic command to line of sight) and the use of an infrared command link replacing the Malkara's manual wire guidance. The name is a randomly selected "rainbow code". The initial contract called for testing in 1960 with a 1962 in-service date. Problems with the command link proved difficult to solve and later appeared to require outright replacement. The project was cancelled in September 1959 as it would not enter service before the Chieftain tank which was considered able to deal with any Soviet tank available. Malkara was purchased for its original intended use to give airborne i ...

Anti-tank Guided Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave lig ...

British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ...

Anti-tank Guided Missiles Of The United Kingdom
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such ...

Humber Hornet
The FV1620 Humber Hornet (FV1620, truck 1-ton, air portable, armoured launcher, Hornet launcher) was a specialised air-deployable armoured fighting vehicle designed to carry the Malkara, an anti-tank guided missile developed by Australia and the United Kingdom. History The Hornet was developed in the 1950s to provide British and Australian airborne units with an air-dropped long-range anti-tank capability. Based on the British Army's FV1611 Humber "Pig" one-ton four-wheel drive armoured truck, it carried two Malkara, missiles on a retractable boom at the rear, as well as two reloads. It could be transported by air in a Blackburn Beverley and air-dropped on a cluster of 6 special parachutes. Operation The gunner fired the missiles from inside the cab and controlled them by means of a joystick attached to a wire which unreeled from the rear of the missile and connected to the sights. Electronic signals controlling the missile's flight were transmitted through the wire. With a ...

Anti-tank Gun
An anti-tank gun is a form of artillery designed to destroy tanks and other armored fighting vehicles, normally from a static defensive position. The development of specialized anti-tank munitions and anti-tank guns was prompted by the appearance of tanks during World War I. To destroy hostile tanks, artillerymen often used field guns depressed to fire directly at their targets, but this practice expended too much valuable ammunition and was of increasingly limited effectiveness as tank armor became thicker. The first dedicated anti-tank artillery began appearing in the 1920s, and by World War II was a common appearance in many European armies. To penetrate armor, they fired specialized ammunition from longer barrels to achieve a higher muzzle velocity than field guns. Most anti-tank guns were developed in the 1930s as improvements in tanks were noted, and nearly every major arms manufacturer produced one type or another. Anti-tank guns deployed during World War II were often manne ...

Christopher Soames
Arthur Christopher John Soames, Baron Soames, (12 October 1920 – 16 September 1987) was a British Conservative politician who served as a European Commissioner and the last Governor of Southern Rhodesia. He was previously Member of Parliament (MP) for Bedford from 1950 to 1966. He held several government posts and attained Cabinet rank. Early life and education Soames was born in Penn, Buckinghamshire, England, the son of Captain Arthur Granville Soames (the brother of Olave Baden-Powell, World Chief Guide, both descendants of a brewing family who had joined the landed gentry) by his marriage to Hope Mary Woodbine Parish. His parents divorced while he was a boy, and his mother married as her second husband Charles Rhys (later 8th Baron Dynevor), by whom she had further children including Richard Rhys, 9th Baron Dynevor. Soames was educated at West Downs School, Eton College, and the Royal Military College at Sandhurst. He obtained a commission as an officer in the C ...

Royal Ordnance L11
The Royal Ordnance L11A5, officially designated Gun 120 mm Tk L11, is a 120 mm L/55 rifled tank gun design. It was the first of NATO's 120 mm main battle tank guns which became the standard calibre for Western tanks in the later period of the Cold War. By 2005, a total of 3,012 L11 guns were produced. List price was US $227,000 (1990). The L11 was developed by Britain's Royal Ordnance Factories to equip the Chieftain tank as the successor to the 105 mm L7 gun used in the Centurion tank. It was also used on the Challenger 1, which replaced the Chieftain in British and Jordanian service. The weapon has been superseded by the L30 series 120 mm rifled tank gun. History The Royal Armament Research and Development Establishment at Fort Halstead designed a new 120 mm rifled tank gun in 1957. The new gun was deemed to be necessary because the British Army specified engagement ranges greater than those of other armies, for example , as specified by the US ...

Scintillation (physics)
Scintillation is the physical process where a material, called scintillator, emits UV or visible light under excitation from high energy photons (X-rays or γ-rays) or energetic particles,(such as electrons, alpha particles, neutrons or ions). See scintillator and scintillation counter for practical applications. Overview The process of scintillation is one of luminescence whereby light of a characteristic spectrum is emitted following the absorption of radiation. The scintillation process can be summarized in three main stages (A) conversion, (B) transport and energy transfer to the luminescence center, and (C) luminescence. The emitted radiation is usually less energetic than the absorbed radiation, hence generally scintillation is a down-conversion process. Conversion processes The first stage of scintillation, conversion, is the process where the energy from the incident radiation is absorbed by the scintillator and highly energetic electrons and holes are created in th ...

CBRN Defense
Chemical, biological, radiological and nuclear defence (CBRN defence) are protective measures taken in situations in which chemical warfare, chemical, biological warfare, biological, radiological warfare, radiological or nuclear warfare, nuclear warfare (including terrorism) hazards may be present. CBRN defence consists of CBRN passive protection, contamination avoidance, and Weapon of mass destruction, weapons of mass destruction mitigation. A CBRN incident differs from a hazardous material incident in both scope (i.e., CBRN can be a mass casualty situation) and intent. CBRN incidents are responded to under the assumption that they are intentional and malicious; evidence preservation and perpetrator apprehension are of greater concern than with HAZMAT incidents. A 2011 forecast concluded that worldwide government spending on CBRN defence products and services would reach US$8.38bn that year. Etymology In English language, English the term ''CBRN'' is a replacement for the 19 ...

Transistor
upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electrical power, power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually constru ...

Hypotenuse
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. For example, if one of the other sides has a length of 3 (when squared, 9) and the other has a length of 4 (when squared, 16), then their squares add up to 25. The length of the hypotenuse is the square root of 25, that is, 5. Etymology The word ''hypotenuse'' is derived from Greek (sc. or ), meaning " idesubtending the right angle" (Apollodorus), ''hupoteinousa'' being the feminine present active participle of the verb ''hupo-teinō'' "to stretch below, to subtend", from ''teinō'' "to stretch, extend". The nominalised participle, , was used for the hypotenuse of a triangle in the 4th century BCE (attested in Plato, ''Timaeus'' 54d). The Greek term was loaned into La ...

Molten Salt Battery
Molten-salt batteries are a class of battery that uses molten salts as an electrolyte and offers both a high energy density and a high power density. Traditional non-rechargeable thermal batteries can be stored in their solid state at room temperature for long periods of time before being activated by heating. Rechargeable liquid-metal batteries are used for industrial power backup, special electric vehicles and for grid energy storage, to balance out intermittent renewable power sources such as solar panels and wind turbines. History Thermal batteries originated during World War II when German scientist Georg Otto Erb developed the first practical cells using a salt mixture as an electrolyte. Erb developed batteries for military applications, including the V-1 flying bomb and the V-2 rocket, and artillery fuzing systems. None of these batteries entered field use during the war. Afterwards, Erb was interrogated by British intelligence. His work was reported in "The Theory and Pr ...
