MAT/5 mine

Last updated

The MAT/5 is an Italian circular, plastic-cased minimum metal blast resistant anti-tank blast mine. It uses a pneumatic fuze which is resistant to shock and blast, and is also claimed to be resistant to mine flails and mine rollers. The mine's plastic case is waterproof, and it can be laid in shallow water. Additionally the mine will function upside down. The mine can be fitted with anti-handling devices. The mine is no longer in production.

Minimum metal mine

A minimum metal mine is a land mine that is designed to use the smallest amount of metal possible in its construction. Typically, the only metal components are located inside the fuze mechanism which triggers detonation. Both minimum metal anti-tank and anti-personnel mines exist. Some designs contain virtually no metal at all e.g. less than a gram. This is achieved by encasing the explosive charge in a plastic, wooden, or glass body, with metallic components limited to the few small parts in the fuze which can not easily be made from other materials, such as the spring, striker tip, and shear pin. Minimum metal mines are extremely difficult to detect using conventional metal mine detectors and usually require modern techniques, such as robotic Multi Period Sensing (MPS) equipment, to identify, but it is still too difficult to find non-metallic mines. These techniques are usually restricted to well-funded international mine clearing organizations and major militaries, making minimum metal mines especially pernicious where they are encountered.

Blast resistant mine

A Blast resistant mine is a landmine with a fuze which is designed to be insensitive to the shock wave from a nearby explosion. This feature makes it difficult or impossible to clear such mines using explosive minefield breaching techniques. As a result, the process of clearing minefields is slower and more complex. Blast resistance can be achieved in a number of ways.

Anti-tank mine form of land mine designed for use against armored vehicles (including tanks)

An anti-tank mine is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles.

Specifications

Composition B

Composition B, colloquially "Comp B", is an explosive consisting of castable mixtures of RDX and TNT. It is used as the main explosive filling in artillery projectiles, rockets, land mines, hand grenades and various other munitions. It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States.

The PMN series of blast anti-personnel mines were designed and manufactured in the Soviet Union. They are one of the most widely used and commonly found devices during demining operations.

VS-1.6 mine

The VS-1.6 is an Italian circular plastic-cased scatterable anti-tank blast mine. It has very few metal components and is resistant to overpressure and shock. The mine can also be deployed conventionally and from helicopters. It was produced by Valsella Meccanotecnica, but production has ceased.

VS-50 mine

The VS-50 is a circular plastic cased anti-personnel blast mine, formerly manufactured by the now-defunct Valsella Meccanotecnica SpA, an Italian high-tech defence industry specialized in area denial systems which was also the manufacturer of the Valmara 69 and one of the first industries in the world to implement plastic construction for landmines. The design is similar to the TS-50 and VS-MK2 mine. It is blast resistant and can be used in a minimum metal configuration. Though unlikely to kill, the explosive charge contained within a VS-50 is quite sufficient to destroy the victim's foot: the blast is capable of penetrating 5 mm of mild steel leaving an 80 mm-diameter hole.

The SB-81 is an Italian plastic cased minimum metal anti-tank blast mine dating from the early 1980s. The mine uses an air pressure based fuze, which gives it protection against overpressure and blast. It can therefore be regarded as a blast resistant mine. The mine can be scattered by hand or by mine laying systems.

Type 72 metallic anti-tank mine

The Type 72 is a Chinese metal-cased circular anti-tank blast mine, it is similar to the Russian TM-46 mine, a plastic cased version of the mine is also produced, the Type 72 non-metallic anti-tank mine. The mine has a central plastic cased blast resistant fuze.

The MAT-76 is a large circular Romanian minimum metal anti-tank blast mine. It is similar to the MAT-62B mine, sharing a fuze. The mine is actually a cast block of TNT with a thin coating of fibreglass. The mine has a central fuze well that normally uses a P-62 pressure fuze, although it can be used with any of the fuzes designed for the Russian TM-62 and TM-72 series of mines. The bakelite plastic used in the fuze of a MAT-76 may become brittle in desert conditions, which can reduce the activation pressure. This may make the mine unstable i.e. can detonate simply by handling it. The mine is found in Angola, Iraq, Kuwait, Liberia, Mozambique, and Zambia.

TMA-4 mine

The TMA-4 is a circular plastic cased Yugoslavian minimum metal anti-tank blast mine. It is a modernized version of the TMA-3. The mine is basically a cast block of TNT with three fuze wells cut into it, encased in plastic. Three black plastic UTMA-4 fuzes are installed into the top surface of the mine. A thin rope carry handle is also provided. The small pressure plate area of the fuzes make the mine resistant to overpressure from explosive demining techniques. Additionally the low metal content of the mine make it very difficult to detect. Although no secondary fuze well is provided, it is possible that the mine could be fitted with improvised anti-handling devices.

The YM-III or YM-3 is a circular ABS plastic cased Iranian minimum metal anti-tank blast mine. It is a copy of the Chinese Type 72 non-metallic anti-tank mine. The mine uses a blast-resistant fuze, which relies on gradual application of pressure to trigger it. The mine is found in Afghanistan, Bosnia, Iran, and Iraq.

The MAT.84-F5 is a Chilean, plastic cased, minimum metal anti-tank blast mine. The mine has a small central pressure plate on the top of the case which is made from 3 mm thick, olive green, high-impact plastic. The mine is armed before it is laid by unscrewing a safety plug from the side of the mine. The mine is believed to be in service with the Chilean armed services.

The BM/85 is an Italian blast resistant bounding anti-personnel mine that was produced by Tecnovar italiana SpA. The mine is cylindrical with a three pronged tilt/pressure fuze on the top with a central post for attaching a tripwire. A plastic safety clip prevents the fuze from tilting when in transit. Once the pressure clip is removed the mine is armed. Once the fuze is pulled sideways by a trip wire or by downward pressure, the mine is triggered. A small charge launches the mine to a height of about 0.45 meters where it explodes scattering 1,000 fragments to a lethal radius of about 25 meters.

PMA-3 mine

The PMA-3 is a Yugoslavian blast resistant minimum metal anti-personnel mine. It is circular, consisting of a plastic upper and lower half joined together by a rubber cover. A safety collar is normally wrapped around the outside of the mine, preventing the upper half of the mine tilting when in transit. Once deployed the safety collar is removed. Sufficient pressure on the top surface of the mine causes it to tilt. The tilting drives a pin through a friction sensitive pyrotechnic compound, which fires the detonator and then the main explosive charge.
