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 It replaced the World War 2-era Mk 5 mine, and has in turn been replaced by the L9 bar mine.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, ...

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 ...

Tilt-rod Fuze
Russian TM-57 mine with a tilt-rod fuze A tilt-rod fuze is a device used to trigger anti-vehicle landmines. Typically it consists of a vertical pole, normally around a meter high, which is connected to the top of a landmine. When the track or main body of a vehicle passes over the mine, the rod is tilted, releasing a spring-loaded striker which triggers a pyrotechnic delay of approximately half a second, followed by detonation of the main explosive charge. The small time delay allows the vehicle to continue over the mine before detonating, exposing more of it to the blast. A tilt-rod fuze has a number of advantages over pressure fuzesit acts across the entire width of a vehicle, rather than just its tracks or tires. This allows it to attack the vehicle's belly and potentially cause a catastrophic kill. Additionally, tilt rod fuzes tend to be resistant to blast overpressure clearing methods, which can trigger most pressure fuzes. The main disadvantage is the visible rod mechani ...

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 ...

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, ...

Tetryl
2,4,6-Trinitrophenylmethylnitramine commonly referred to as tetryl ( C7 H5 N5 O8) is an explosive compound used to make detonators and explosive booster charges. Tetryl is a nitramine booster explosive, though its use has been largely superseded by RDX. Tetryl is a sensitive secondary high explosive used as a booster, a small charge placed next to the detonator in order to propagate detonation into the main explosive charge. Chemical properties Tetryl is a yellow crystalline solid powder material, practically insoluble in water but soluble in acetone, benzene and other solvents. When tetryl is heated, it first melts, then decomposes and explodes. It burns readily and is more easily detonated than ammonium picrate or TNT, being about as sensitive as picric acid. It is detonated by friction, shock, or spark. It remains stable at all temperatures which may be encountered in storage. It is generally used in the form of pressed pellets, and has been approved as the standard bursting ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booster Charge
{{unreferenced, date=August 2011 An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge. However, it detonates the primary charge (the booster), which then delivers an explosive shockwave that is sufficient to detonate the secondary, main, high-energy charge. Unlike C4 plastic explosive, not all explosives can be detonated simply by inserting a detonator and firing it. An initiator such as a shock tube, cannon fuse, or even a conventional detonator does not deliver sufficient shock to detonate charges comprising TNT, Composition B, ANFO and many other high explosives. Therefore, some form of "booster" is required to amplify the energy released by the detonator so that the main charge will detonate. At first, picric acid was u ...

Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation. ...

Anti-handling Device
An anti-handling device is an attachment to or an integral part of a landmine or other munition such as some fuze types found in general-purpose air-dropped bombs, cluster bombs and sea mines. It is designed to prevent tampering or disabling, or to target bomb disposal personnel. When the protected device is disturbed, it detonates, killing or injuring anyone within the blast area. There is a strong functional overlap of booby traps and anti-handling devices. Purpose Anti-handling devices prevent the capture and reuse of the munition by enemy forces. They also hinder bomb disposal or demining operations, both directly and by deterrence, thereby creating a much more effective hazard or barrier. Anti-handling devices greatly increase the danger of munitions to civilian populations in the areas in which they are used because their mechanisms are so easily triggered. An anti-tank mine with an anti-handling device fitted is almost guaranteed to detonate if it is lifted/overturned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-tank Mines 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 as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
