The VS-50 is a circular plastic-cased anti-personnel blast mine that entered production in 1985. It was formerly made by the now-defunct Valsella Meccanotecnica SpA, an Italian high-tech defence company specialized in area denial systems. The company also the made the Valmara 69, and was one of the first to implement plastic construction for landmines. [1] The VS-50's design is similar to that of the TS-50 and VS-MK2 mines. It is blast resistant and can be used in a minimum metal configuration. Though unlikely to kill, its explosive charge is quite sufficient to destroy the victim's foot, being capable of penetrating 5 mm of mild steel leaving an 80 mm-diameter hole.
The mine consists of three sections, a bottom section containing the main explosive charge, a middle section which contains the fuze and safety/arming mechanism, and the top section which consists of a neoprene pressure pad. The neoprene pressure pad is sometimes reinforced with an 18 gram mild steel plate, which makes the mine detectable by metal detectors. However, the majority of VS-50s were manufactured as minimal metal mines and are therefore much harder to detect. The case is waterproof and can be used in water up to one metre deep. The mine can be deployed by helicopters or ground vehicles or laid by hand.
A sustained downward force of approximately ten kilograms on the pressure plate for a minimum of 0.10 seconds compresses the firing spring and cocks the striker. Continuous downward movement allows the trigger assembly to pivot, slowly forcing the air out of an anti-shock bladder and flips the striker down into the stab sensitive M41 detonator, at which point the mine explodes.
The air pressure delay mechanism effectively blocks detonation if the force on the pressure plate is of short duration, because air does not have enough time to leave the small anti-shock bladder. This has two direct applications: allowing the mine to be dropped from helicopter mine scattering systems, and dramatically increasing the mine's resistance to explosive-based mine clearance techniques. It can therefore be regarded as a blast resistant mine.
The VS-50AR is an electronically fuzed version of the mine which contains an integral mercury tilt switch, that operates as an anti-handling device. The VS-50AR has a dummy pressure plate on top and its external appearance is very similar to the VS-50, which has obvious implications for demining personnel. The VS-50AR contains a reduced explosive charge, but which is still sufficient to blow the victim's hands off.
Additionally, Valsella manufactured a completely separate electronic anti-handling device known as the VS-AR4. This was a tilt-operated device, specifically designed to be fitted to any of the following Valsella products: the VS-50 (standard version, not the VS-50AR) and Valmara 69 anti-personnel mines, as well as the VS-1.6 and VS-1.2 anti-tank mines. The VS-AR4 has a series of fuze adaptors which allow it to be screwed into the bottom of any of those mines. It has a 10-minute mechanical arming delay (started by removing a pin) followed by a 30-minute electronic arming delay. The power source are two 1.5 V batteries and the operational life is longer than a year.
Generally, the render safe procedure for VS-50 mines with anti-handling devices fitted is to detonate them in place via a donor charge, or burn through the plastic casing using some form of special incendiary device.
The mine has been encountered in Afghanistan, Angola, Ecuador, Iraq, Turkey, Kuwait, Lebanon, Peru, Rwanda, Sri Lanka, the Western Sahara and Zimbabwe.
Valmara 69 or V-69 is an Italian bounding anti-personnel mine manufactured by Valsella. The mine was developed from the V-59 mine, and although the mine is no longer produced in Italy, a number of copies were produced in other countries e.g. the "SPM-1" manufactured by Singapore.
Type 72 Non-Metallic is a Chinese circular, plastic bodied landmine which is designed to damage or destroy a vehicle by blast effect.
The M14 mine "Toepopper" is a small anti-personnel land mine first deployed by the United States circa 1955. The M14 mechanism uses a belleville spring to flip a firing pin downwards into a stab detonator when pressure is applied. Once deployed, the M14 is very difficult to detect because it is a minimum metal mine, i.e. most of its components are plastic. Because of this, the design was later modified to ease mine clearance with the addition of a steel washer, glued onto the base of the mine.
The SB-33 is a small Italian minimum metal blast type anti-personnel mine formerly manufactured by Misar, that entered service in 1977. The SB-33 can be emplaced by hand or scattered using the helicopter mounted SY-AT system.
The PROM-1 is a Yugoslavian manufactured bounding anti-personnel mine. It consists of a cylindrical body with a pronged fuze inserted into the top of the mine. It is broadly similar in operation to the German S-mine.
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. They are sometimes nicknamed "black widow" because of their dark casings.
The VS-MK-2 is a plastic bodied scatterable anti-personnel blast mine manufactured by the now-defunct Valsella Meccanotecnica, SpA, an Italian high-tech defence contractor that specialized in the development and production of area denial systems. The mine is extremely difficult to detect because of its low metal content i.e. it is a minimum metal mine. Additionally, it is resistant to blast overpressure due to a pneumatic system in the fuze. The mine will also function in up to 1 metre of water. An electrically fused anti-handling version of the mine was also produced designated VS-MK-2-EL, VS-MK-2-E or VS-MK2 AR-AN to hinder clearance attempts. Although Italy has ceased production of this mine it may still be found in uncleared minefields located in Angola, Sudan and the Western Sahara.
The M15 mine is a large circular United States anti-tank blast mine, first deployed during the Korean War. Essentially, it is a larger version of the M6A2 anti-tank mine, which it replaced. Although the M15 has been superseded by the M19 mine, the U.S. retains large stocks of M15s because they are still regarded as reliable and effective weapons. When used against main battle tanks the M15 is primarily a "track-breaker" which creates mobility kills, but has a comparatively small likelihood of causing crew fatalities. However, when used against light vehicles such as APCs or unarmored vehicles such as trucks the damage it can inflict is much more severe.
The VS-2.2, VS-3.6 and SH-55 are Italian circular plastic cased anti-tank blast mines that use the VS-N series fuze. They have very few metal components and are resistant to overpressure and shock. The VS-2.2 and VS-3.6 can also be deployed from helicopters. It was produced by Valsella Meccanotecnica and Singapore, but production has ceased. The VS-2.2 and VS-3.6 are essentially the same, the VS-3.6 being slightly larger, the SH-55 is larger still and has a more rounded appearance. A smaller mine, the VS-1.6 also uses the same fuze.
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.
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.
The Valmara 59 is a large cylindrical Italian bounding anti-personnel mine. It is the first in the "Valmara" family of mines produced by Valsella Meccanotecnica, and was followed by the Valmara 69 and VS-JAP. The mine's body is plastic with a distinctive five-pronged metal head. The central prong has a hole, to allow the threading a trip wire. The inner body of the mine has a main charge surrounded with approximately 1,000 steel cubes, below which is a steel wire connecting it to the base of the mine. When the mine is triggered a small charge launches the mine into the air approximately 45 cm before the steel wire is pulled taut, the jolt of which pulls a striker into the detonator. A secondary time fuse triggers the mine after three seconds if it has not detonated after being triggered.
The VS-JAP is an Italian bounding anti-personnel mine. It is the latest of the Valmara family of bounding mines that includes the Valmara 59 and Valmara 69. The mine has a waterproof plastic faceted cylindrical body with a three-pronged cap, with a central fixing point for a tripwire. The fuze is triggered via downward or sideways pressure.
The FMK-1 is a small circular Argentina anti-personnel blast mine which, when fitted with a stiffened pressure plate, is also used as the fuze for the FMK-3 and FMK-5 anti-tank mines. The mine has a circular plastic body, with a number of small ribs running vertically around the outside of the mine, with the circular detonator and striker protruding on each side. The pressure plate has a distinctive six pointed star shape ribbing for stiffness. The bottom of the mine has small base plug inside which a small stud is installed. The stud increases the activation pressure of the mine. A metal detector disc can be added to the bottom of the mine, but it is not often used. It is actually in service with the Argentine Army.
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.
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 VAR/40, VAR/100 and VAR/100/SP are Italian anti-personnel blast landmines produced by the Tecnovar italiana S.p.A. company.
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.
The TS-50 is a 90 mm (3.5 in) diameter circular Italian blast resistant minimum metal anti-personnel mine designed and produced by Valsella Meccanotecnica (Italy).
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.
