Mk 5 Mine
The Anti-Tank Mine, General Service, Mk V was a cylindrical, metal-cased United Kingdom anti-tank blast mine that entered service in 1943, during the Second World War. It was replaced in British service with the Mk 7 mine. Two versions of the mine were produced, the ''Mk. V'' and the ''Mk. VC'' with the same external dimensions. The only difference was that the Mk. VC had a half-sized explosive charge. The mine used a spider pressure plate that makes it resistant to blast overpressure. The spider rests on a central Mk 3 fuse (sometimes referred to as No.3 Mk I), which contains a spring-loaded striker held in place by a shear pin. The mine, being made largely of steel tended to rust making its activation unpredictable. It is found in Angola, Egypt, Jordan, Libya, Mozambique, Sudan, and Zimbabwe Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, ...

Anti-tank Mine
An anti-tank mine (abbreviated to "AT mine") is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles. Compared to anti-personnel mines, anti-tank mines typically have a much larger explosive charge, and a fuze designed to be triggered by vehicles or, in some cases, remotely or by tampering with the mine. History First World War The first anti-tank mines were improvised during the First World War as a countermeasure against the first tanks introduced by the British towards the end of the war. Initially they were nothing more than a buried high-explosive shell or mortar bomb with its fuze upright. Later, purpose-built mines were developed, including the Flachmine 17, which was simply a wooden box packed with explosives and triggered either remotely or by a pressure fuze. By the end of the war, the Germans had developed row mining techniques, and mines accounted for 15% of U.S. tank casualties during the Battle of Saint-Mih ...

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] |
TNT (explosive)
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that in ...

Baratol
Baratol is an explosive made of a mixture of TNT and barium nitrate, with a small quantity (about 1%) of paraffin wax used as a phlegmatizing agent. TNT typically makes up 25% to 33% of the mixture. Because of the high density of barium nitrate, Baratol has a density of at least 2.5 g/cm3. Baratol, which has a detonation velocity of only about 4,900 metres per second, was used as the slow-detonating explosive in the explosive lenses of some early atomic bomb designs, with Composition B often used as the fast-detonating component. Atomic bombs detonated at Trinity in 1945, the Soviet Joe 1 in 1949, and in India in 1972 all used Baratol and Composition B. Baratol was also used in the Mills bomb, a British hand grenade A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher.

Mk 7 Mine
The Mk 7 mine was a circular British anti-tank blast mine. It replaced the World War 2-era Mk 5 mine, and has in turn been replaced by the L9 bar mine. The Mk 7 can be laid either by hand or from a mechanical mine layer. The mine is conventional in design. It has a steel casing with a central, main fuze well, below which is a tetryl booster charge, both surrounded by the main explosive filling of TNT. The mine can be fitted with a variety of fuzes, including a double-impulse fuze (which gives it some resistance to explosive demining methods) or the L93A1 tilt-rod fuze, which gives it a full width attack capability. The mine has a secondary fuze well for an anti-lifting device and a mechanical anti-handling device was also produced for the mine, although this is reported to have never been used. The mine is currently being phased out of service with the British army. The mine is found in Afghanistan, Angola, Cyprus, Egypt, Eritrea, Ethiopia, Lebanon, Libya, Namibia, Oman, Somalia, ...

Shear Pin
{{unreferenced, date=September 2018 A shear pin is a mechanical detail designed to allow a specific outcome to occur once a predetermined force is applied. It can either function as a safeguard designed to break to protect other parts, or as a conditional operator that will not allow a mechanical device to operate until the correct force is applied. Shear pins as safeguards In the role of a mechanical safeguard, a shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more expensive or less-easily replaced parts from being damaged. As a mechanical sacrificial part, it is analogous to an electric fuse. They are most commonly used in drive trains, such as a snow blower's auger or the propellers attached to marine engines. Another use is in pushback bars used for large aircraft. In this device, shear pins are frequently used to connect the "head" of the towbar – the portion that attaches to the aircraft – to the main shaft of t ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...
