MAG deminer disarms VS-50 landmine in Dohuk governorate

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 Valsella Meccanotecnica SpA (also known as Valsella) 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 comp ...

SpA, an Italian high-tech defence company specialized in area denial systems. The company also made the Valmara 69, and was one of the first to implement plastic construction for landmines. 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

Description

The mine consists of three sections, a bottom section containing the main explosive charge, a middle section which contains the

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.

Operation

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

, 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

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

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
