VS-1.6 Anti-Tank Mine
Overview
The VS-1.6 is an Italian circular plastic-cased scatterable anti-tank blast mine designed and manufactured by Valsella Meccanotecnica SpA. A minimum-metal mine with exceptional blast and shock resistance, the VS-1.6 represents one of the most technically sophisticated anti-tank mines of its era. Its pneumatic fuze system and sealed construction allow deployment in challenging environments including underwater up to one meter depth. The mine can be emplaced by hand or scattered from helicopter-mounted dispensers, providing significant tactical flexibility. While originally designed to destroy or disable armored vehicles, its relatively small explosive charge (1.85 kg) means it typically disables rather than destroys targets.

Fuzing Mechanisms
Primary Fuze System: Pneumatic Pressure Fuze
The VS-1.6 employs an air-pressure driven fuzing system designed to provide blast and shock resistance while maintaining reliability under vehicle pressure.
Operating Sequence
- Pressure Application: Vehicle weight applies pressure to the mine’s top plate
- Air Compression: Pressure forces air into a sealed internal diaphragm chamber
- Diaphragm Inflation: Air gradually inflates the diaphragm
- Locking Collar Rotation: The striker must first rotate a locking collar mechanism
- Striker Release: Once the collar is rotated, the striker is released to impact the detonator
- Detonation: Detonator initiates booster and main charge
Blast Resistance Features
The pneumatic fuze provides exceptional blast resistance through two mechanisms:
- Duration Sensitivity: The diaphragm inflation requires sustained pressure over time; shock waves from explosions are too brief (milliseconds) to cycle the fuze
- Rotational Interlock: The requirement for the striker to rotate a locking collar before release adds a second duration-dependent step; this cannot occur under the instantaneous loading of an explosion
These combined features make the VS-1.6 highly resistant to explosive mine clearance techniques including:
- Explosive line charges
- Bangalore torpedoes
- Mine-clearing charges
- Artillery and mortar fire
- Aerial bombing
Electronic Variant: VS-1.6EL
The VS-1.6EL incorporates an electronic fuze with enhanced capabilities:
- Integral Anti-Handling Device: Built-in tilt sensitivity
- Programmable Self-Destruct: Can be set to self-neutralize after a specified time
- Enhanced Reliability: Electronic initiation system
VS-AR4 Anti-Handling Device
A separate electronic anti-handling device (VS-AR4) can be fitted to the bottom of standard VS-1.6 mines:
| Feature | Specification |

| Power Source | Two 1.5V batteries |
| Operational Life | >1 year |
| Compatible Mines | VS-1.6, VS-1.2, VS-50, Valmara 69 |
VS-AR4 Installation
The VS-AR4 has fuze adaptors that allow it to be screwed into the secondary fuze well in the bottom of compatible Valsella mines.
Safety/Arming
- Mine is armed upon emplacement when safety features are removed
- No external visual indication of armed status
- Cushioning bands suggest aerial deployment capability but do not indicate armed/safe status
Render Safe Considerations
- Standard VS-1.6: May be rendered safe by qualified EOD personnel
- VS-1.6 with VS-AR4 or VS-1.6EL: Standard render-safe may cause detonation
- Recommended procedure for anti-handling device variants: Destruction in place via donor charge or specialized incendiary device to burn through the plastic case
History of Development and Use
Development Background
The VS-1.6 was developed by Valsella Meccanotecnica during the 1970s-1980s as part of a comprehensive anti-tank mine family. The design philosophy emphasized:
- Scatterability: Capability for rapid aerial deployment from helicopters
- Minimal Detectability: Plastic construction to defeat metal detectors
- Blast Resistance: Pneumatic fuzing to resist explosive clearance
- Modularity: Common fuzing across multiple mine sizes
Valsella Meccanotecnica
Valsella became one of the world’s most successful mine manufacturers during the 1980s. The company’s profits soared dramatically:
- 1981: 10 billion lire
- 1982: 80 billion lire
- 1983: 107 billion lire
This growth was driven by significant export contracts, particularly to the Middle East.
Technology Transfer
Between 1982 and 1986, Valsella exported disassembled mines, components, and detonators to Chartered Industries of Singapore (CIS) worth approximately $37 million USD. Over 3,800 metric tons of weapons, primarily landmines, were exported to Singapore during this period, establishing Singapore as a major mine producer using Italian technology.
Combat Deployment
Gulf War (1990-1991)
The VS-1.6 saw its most extensive combat use during the 1990-1991 Gulf War:
- Hundreds of thousands of VS-1.6 mines were emplaced in Kuwait and Iraq
- Iraqi forces deployed these mines as part of defensive obstacles
- Many mines remain uncleared decades later
- The extensive use of VS-1.6 mines in Kuwait made it one of the most mine-contaminated countries post-war
Other Conflicts
The VS-1.6 has been documented in:
- Iraq (Iran-Iraq War, Gulf War)
- Kuwait (Gulf War)
- Lebanon (various conflicts)
- Burma/Myanmar (internal conflicts)
- Western Sahara (territorial disputes)
Mine Dispersal Systems
Valsella developed specialized delivery systems for the VS-1.6:
- VS MD Helicopter Dispenser: Capacity of 200 VS-1.6 mines; supplied to Morocco among other customers
- Istrice: Vehicle-mounted mine-laying system introduced in 1987
- Grillo: Additional mine-laying system
Italian Mine Ban
Italy adopted mine-related restrictions beginning in 1994:
- August 2, 1994: Moratorium on antipersonnel mine production and trade
- Law 374/97: Comprehensive mine legislation
Following these changes, Valsella’s military production collapsed:
- 1996-1997: Losses of 16 billion lire
- Company eventually converted to civil production
- Valsella is no longer involved in mine production
Current Status
- Production: Discontinued
- Manufacturer: Valsella no longer produces military ordnance
- UXO Presence: Extensive contamination remains in Gulf War-affected areas
- Clearance Status: Ongoing demining operations in Kuwait, Iraq, and other affected regions

Frequently Asked Questions
Q: What is the difference between the VS-1.6 and the VS-2.2? A: While both are Valsella anti-tank mines with similar pneumatic fuzing principles, there are key differences. The VS-1.6 is smaller (222mm diameter, 92mm height, 1.85kg explosive) and designed primarily for scatterable deployment from helicopters. The VS-2.2 is larger (230mm diameter, 115mm height, 2.2kg explosive) and uses the VS-N fuze system. The VS-2.2 also has a ribbed body appearance and a visible secondary fuze well for anti-handling devices. The VS-1.6’s distinctive circumferential cushioning bands for aerial deployment are absent on the VS-2.2.
Q: How can the VS-1.6 be deployed underwater? A: The VS-1.6’s sealed plastic construction makes it waterproof, allowing deployment in water up to 1 meter deep. This capability enables use in shallow coastal areas, stream crossings, rice paddies, and other wet environments. The sealed nature also protects the fuze mechanism from moisture intrusion that could cause malfunction. The pneumatic fuze operates identically underwater since it relies on internal air pressure rather than external atmospheric conditions.
Q: What makes the VS-1.6 resistant to explosive mine clearance? A: The VS-1.6’s pneumatic fuze requires sustained pressure over time to function. When pressure is applied, air must flow through internal passages to inflate a diaphragm, and the striker must rotate a locking collar. Explosive shock waves from mine clearance charges last only milliseconds—far too brief to complete this multi-step process. Consequently, explosive breaching may fail to detonate the mine, leaving it armed and requiring manual clearance.
Q: Why is the VS-1.6 described as causing “mobility kills” rather than destroying vehicles? A: The VS-1.6’s 1.85 kg Composition B charge is relatively small compared to other anti-tank mines. This charge is sufficient to destroy vehicle tracks or wheels and damage the hull underside, effectively immobilizing (“mobility killing”) the vehicle. However, it typically lacks the explosive power to completely destroy a modern main battle tank or cause catastrophic crew casualties in well-armored vehicles. This design reflects the tactical concept that immobilized vehicles can be engaged by other weapons or create obstacles blocking routes.
Q: What are the circumferential bands around the VS-1.6? A: The two rubber or plastic bands around the mine’s circumference are shock-absorption features designed for aerial deployment. When the VS-1.6 is scattered from helicopter-mounted dispensers (VS MD system), these bands cushion the impact when the mine lands, preventing damage to the fuze mechanism and ensuring reliable function. The bands are a visual identification feature distinguishing the VS-1.6 from non-scatterable anti-tank mines.
Q: How does the VS-AR4 anti-handling device affect clearance procedures? A: The VS-AR4 is a tilt-sensitive electronic device that detonates the mine if disturbed. When fitted to a VS-1.6, standard render-safe procedures (lifting, turning, or otherwise manipulating the mine) will trigger the device. The VS-AR4 has a 10-minute mechanical arming delay followed by a 30-minute electronic arming delay after the safety pin is removed. Its battery life exceeds one year. For mines suspected of having VS-AR4 devices, the recommended disposal method is destruction in place using donor charges or specialized incendiary devices that burn through the plastic case.
Q: How many VS-1.6 mines were deployed in the Gulf War? A: Exact figures are difficult to verify, but reports indicate that hundreds of thousands of VS-1.6 mines were deployed in Kuwait and Iraq during the 1990-1991 Gulf War. This massive deployment made Kuwait one of the most heavily mine-contaminated countries following the conflict. Many of these mines remain uncleared, and the combination of plastic construction, blast resistance, and potential anti-handling devices makes ongoing clearance operations challenging and dangerous.
Q: Is the VS-1.6 still manufactured? A: No, the VS-1.6 is no longer manufactured. Valsella Meccanotecnica ceased military production following Italian mine ban legislation in the late 1990s. The company converted to civil production and is no longer involved in mine manufacturing. However, technology transferred to Singapore enabled Chartered Industries of Singapore to produce similar mines. Existing VS-1.6 stockpiles and deployed mines continue to pose hazards worldwide.
