VS-SATM1 mine

Last updated

The VS-SATM1 is an Italian scatterable anti-tank landmine that was produced by Valsella Meccanotecnica SpA. The mine can be scattered by a GRILLO-128 man-portable single-tube launcher system or a VS-MDH helicopter based system. The mine has six pop-out fins which slow its descent and improve the dispersion characteristics.

Valsella Meccanotecnica SpA was one of Italy's largest manufacturers of land mines. The Company's headquarters initially were in Montichiari. It had two production plants in Castenedolo near Brescia, Italy. The three companies of Valsella, Tecnovar Italiana SpA, and Misar SpA together were the centre of Italian mine production.

The mine uses an electronic fuze with a ten-minute arming delay and a programmable life of between one hour and one year, which is set in one-hour increments. After the programmable life expires, the mine either self-destructs or self-neutralizes. The fuze is an electronic full-width device that probably uses magnetic and seismic sensors. The mine can also function underwater. The fuze contains an integral anti-handling device to hinder deminers.

In military munitions, a fuze 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.

Anti-handling device

An anti-handling device is an attachment to or integral part of a landmine or other munition e.g. some fuze types found in general purpose air-dropped bombs, cluster bombs and sea mines. It is designed to prevent tampering. 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.

The mine's warhead is a shaped charge, optimized to produce maximum spalling behind armour — it can blast a 45-millimeter-diameter hole through a 100-millimeter-thick armour plate.

Shaped charge explosive charge shaped to focus the effect of the explosives energy

A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Various types are used to cut and form metal, initiate nuclear weapons, penetrate armor, and perforate wells in the oil and gas industry.

Spall

Spall are flakes of a material that are broken off a larger solid body and can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure. Spalling and spallation both describe the process of surface failure in which spall is shed.

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.

TM-62 series of mines

TM-62 is the designation for a series of Soviet anti-tank blast mines. The mines have a central fuze and typically have a 7.5 kg explosive charge, however they vary greatly in detail. The mines can be laid manually or automatically from a mine laying machine including the PMR-1, PMR-2 wheeled towed mine layers, the GMZ tracked mine laying vehicle and the VMR-2 helicopter mine laying system.

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.

The Panzer-Stabmine 43 was a German anti-tank mine, together with the Hohl-Sprung mine 4672 it was the first mine to combine a shaped charge warhead with a tilt-rod fuze. The mine was developed during the Second World War. The mine consisted of a wine glass shaped metal main body mounted on a wooden post, with a tilt rod holding arm projecting to one side. It used a 125 mm diameter warhead with 1.6 kg of explosive, and a combination pressure/tilt fuze.

The VS-AT4 and VS-AT4-EL are Italian minimum metal blast resistant anti-tank blast mines. The VS-AT4 uses a blast-resistant mechanical pressure fuze, while the VS-AT4-EL uses a programmable electronic pressure fuze with an integral anti-lifting function.

FFV 028 mine

The FFV 028 is a series of steel cased Swedish anti-tank mines that use electronic fuzes. The mines are circular, with a large Misznay Schardin effect warhead in the center of the mine, with the fuzing and sensor electronics located in the dead space above the main charge. The design of the mine dates from the 1970s and uses a magnetic influence sensor to detonate the mine, making it able to attack the full width of armoured vehicles.

The HAK-1 is a Hungarian plastic encased anti-tank mine. It uses a Misznay Schardin effect warhead combined with an electronic acoustic and magnetic influence fuze. The mine can be programmed for an active life of between three hours and 150 days. Once the acoustic sensor detects a target, the magnetic influence sensor is used to detonate the mine at the optimal point. The warhead is capable of penetrating 45 mm of armour and producing a 130 mm diameter hole.

The VS-HCT series of mines are Italian plastic cased anti-tank mines that use Misznay Schardin effect warheads and have a dual seismic and magnetic fuze. The mines are no longer produced and differ in size and shape.

HPD series of mines

The HPD-1, HPD-2 and HPD-3 are a series of French electrically fuzed anti-tank landmines that use Misznay Schardin effect warheads. The entire series of mines conform to the United States MIL-STD-331.

The MI AC Disp F1 Minotaur mine is a French scatterable anti-tank mine. The mines can also be scattered from 155 millimetre artillery shells, which can hold six of the mines. The mine is cylindrical with two Misznay Schardin effect warheads, one on each side of the mine, with a 600 gram charge. The warhead is claimed to be able to penetrate 90 mm of armour at a distance of 0.5 m. It uses a magnetic influence fuze combined with an anti-handling device which arms itself 64 seconds after launch. At the end of its active life, which is set to between one and 96 hours the mine self-destructs. The land based scattering system can launch mines to a range of up to 300 m.

MN-111

The MN-111 is a Polish air-dropped anti-tank landmine. The mine is designed for use on soft ground. The mine is cylindrical with six spring-loaded fins attached to one end of the mine, with the cylinder drawn to a point at the opposite end which is topped with a small wind vane. The mine is stored with the fins wrapped round the outside of the mine. Once the mine is dropped from the aircraft the fins spring outward, acting as a drag parachute, slowing the rate of descent to a peak speed of about 60 meters per second. As the mine drops the wind vane spins, generating the power used to arm the mine.

MN-121 mine

The MN-121 is a Polish scatterable anti-tank mine, externally similar to the German AT-2 mine. The mine is cylindrical with ten wire legs which fold outward to keep the mine upright. The mine uses a magnetic influence fuze, which triggers the mine when a vehicle passes over it. The mine also has an anti-handling device which triggers the mine if it is moved. The mine's warhead is a shaped charge design containing approximately 700 grams of RDX. The manufacturer claims that it is capable of penetrating 60 millimeters of armour at an offset of half a meter.

The MN-123 is a Polish scatterable anti-tank mine. The mine is a flat cylinder, with a bevelled edge. It is normally deployed from a ground vehicle, using a dispensing system holding 80 mines. The mine can also be manually laid. Like the MN-121 mine, it uses a magnetic influence fuze which detects when a vehicle passes over it. It also has an anti-handling device. Both faces of the mine have a Misznay Schardin effect shaped charge, which is reportedly able to penetrate 60 millimeters of armour at an offset of 0.3 meters.

MPB mine

The MPB is a Polish off-route anti-tank mine. It was developed by BELMA with its partner Military Institute of Engineer Technology. The MPB consists of a metal cylinder filled with explosives, mounted horizontally in an adjustable frame. The mine is intended to be hidden from direct view of the intended target, off to the side of a probable vehicle route, usually a road, to attack the weaker armour on the sides and rear of a vehicle. The mine can be triggered by either a contact fuze or an influence fuze based on infra-red and acoustic sensors, and is also fitted with an anti-handling device. When used with the passive infrared fuze, an acoustic sensor detects approaching vehicles and activates the infra-red sensor, which triggers the mine at an optimal moment as the target passes. The mine can be programmed to self-destruct after either 1, 10 or 30 days have passed.

The MSM MK2 is a Finnish belly attack anti-tank mine. The mine has a circular ribbed plastic case that is tapered towards the bottom. It uses an electronic fuze with a combination magnetic and seismic fuze; it also has an anti-handling device. The mine is armed by inserting an arming pin, which completes an electronic circuit. The mine indicates that it is armed by lighting a small LED light which switches off after 10 minutes. When a vehicle approaches, vibrations travelling through the ground trigger the seismic sensor, which activates the magnetic sensor. When a vehicle passes over the mine, the warhead is triggered. First a clearing charge fire, removing up to 100 millimeters of earth from the top of the mine, then a copper-lined Misznay Schardin effect warhead is triggered. This projects a slug of copper at high velocity into the bottom of the target.
