VS-2.2 Anti-Tank Mine
Overview
The VS-2.2 is an Italian circular plastic-cased anti-tank blast mine designed and manufactured by Valsella Meccanotecnica SpA. Part of the VS-N fuze family of mines, the VS-2.2 features a distinctive ribbed body, minimum-metal construction, and an advanced pneumatic fuzing system that provides exceptional resistance to blast overpressure and shock. The mine can be deployed conventionally by hand or scattered from helicopters, making it suitable for rapid minefield establishment. With a 2.2 kg Composition B main charge, the VS-2.2 is designed to disable rather than destroy armored vehicles, achieving “mobility kills” by damaging tracks, wheels, and vehicle undersides.

Sensitivity Characteristics
| Parameter | Value |
|---|---|
| Operating Pressure | 180-220 kg (397-485 lbs) |
| Blast Resistance | High |
| Shock Resistance | High |
Anti-Handling Device Hazards
The VS-2.2 features a secondary fuze well on the bottom of the mine, offset from center, which can accommodate pull fuzes as anti-handling devices:
- Hidden Location: The secondary fuze well cannot be seen from above
- Pull Fuze Function: If a pull fuze is installed, any attempt to lift or turn the mine will cause detonation
- Field Installation: Anti-handling devices may be added in the field, making it impossible to determine mine configuration from visual inspection alone
Environmental Considerations
- Plastic case provides environmental resistance
- Sealed construction protects internal components
- Long-term UV exposure may degrade plastic
- Desert deployment common; sandy color variants exist
UXO Hazards
- Documented presence in Iraq and Kuwait
- Extensive deployment during Iran-Iraq War and 1990-1991 Gulf War
- Minimum metal construction complicates detection
- Potential anti-handling devices prevent safe lifting
- Plastic construction provides natural camouflage in desert environments
Danger Radius
- Vehicle Damage: Track/wheel destruction; potential hull damage
- Personnel Hazard: Lethal within approximately 5-10 meters
- Charge size produces mobility kills rather than catastrophic vehicle destruction

Fuzing Mechanisms
Primary Fuze System: VS-N Pneumatic Fuze
The VS-2.2 employs the VS-N series air-pressure driven fuze, a sophisticated mechanism providing exceptional blast and shock resistance.
Operating Sequence
- Pressure Application: Vehicle weight applies pressure to the top plate of the VS-N fuze
- Air Compression: Downward pressure forces air into an internal chamber containing a flexible diaphragm
- Diaphragm Inflation: Air gradually inflates the diaphragm under sustained pressure
- Ball Displacement: The expanding diaphragm exerts force on the striker mechanism until a steel retaining ball is forced into a recess, freeing the striker
- Striker Release: With the ball displaced, the spring-loaded striker impacts the detonator
- Detonation Sequence: Detonator → Booster → Main charge
Blast Resistance Mechanism
The VS-N fuze achieves blast resistance through duration-dependent actuation:
| Input Type | Duration | Result |
|---|---|---|
| Explosive Blast | Milliseconds | Insufficient to inflate diaphragm; no detonation |
| Mine Flail/Roller | Very brief | Insufficient duration; may not detonate |
| Vehicle Passage | Seconds | Sufficient duration; mine detonates |
This design philosophy means that:
- Explosive line charges typically fail to clear VS-2.2 mines
- Bangalore torpedoes may be ineffective
- Mine flails and rollers may not reliably detonate the mine
- Only actual vehicle pressure provides the sustained load needed for actuation
Secondary Fuze Well / Anti-Handling Device
The VS-2.2 incorporates a secondary fuze well specifically designed for anti-handling devices:
Location and Design
- Position: Bottom of mine, offset from center
- Visibility: Cannot be seen when mine is in place
- Threading: Standard pull fuze thread pattern
- Purpose: Accommodates pull fuze to prevent mine lifting
Anti-Handling Function
When a pull fuze is installed in the secondary well:
- The fuze body is secured in the fuze well
- A wire or cord connects the fuze’s pull ring to an anchor (stake, buried weight)
- Any attempt to lift the mine pulls the fuze’s striker-retaining pin
- The pull fuze detonates, initiating the main charge
Tactical Implications
- Personnel cannot visually confirm presence or absence of anti-handling devices
- All VS-2.2 mines must be treated as potentially fitted with anti-handling fuzes
- Standard render-safe procedures may not be applicable
- Destruction in place may be required
Safety/Arming
- Mine is armed when VS-N fuze is installed and safety features removed
- No external armed/safe indicator
- Anti-handling device arming is separate from main fuze

Frequently Asked Questions
Q: How does the VS-2.2 compare to the VS-1.6 and VS-3.6? A: The VS-2.2 occupies the middle position in Valsella’s VS-N fuze mine family. The VS-1.6 is smaller (1.85 kg explosive, 222mm diameter) with circumferential cushioning bands for aerial deployment. The VS-3.6 is larger (4 kg explosive, 248mm diameter) and capable of greater vehicle damage. All share the VS-N pneumatic fuze system and minimum-metal construction. The VS-2.2 balances portability with effectiveness, offering more destructive potential than the VS-1.6 while remaining lighter than the VS-3.6.
Q: Where is the secondary fuze well located and why is its position significant? A: The secondary fuze well is located on the bottom of the mine, slightly offset from center. This position is highly significant for clearance operations because the fuze well cannot be seen when the mine is emplaced with the bottom against the ground. Personnel cannot visually confirm whether an anti-handling device has been installed without moving the mine—the very action that would detonate an anti-handling fuze. This design feature makes all VS-2.2 mines potentially booby-trapped and requires treating every encounter with extreme caution.
Q: What type of anti-handling device is typically used with the VS-2.2? A: The VS-2.2’s secondary fuze well is designed to accept pull fuzes. When installed, a pull fuze is connected via wire to an anchor point (such as a stake or buried weight). Lifting the mine pulls the fuze’s striker-retaining mechanism, triggering detonation. Unlike the electronic VS-AR4 anti-handling device used with other Valsella mines, the pull fuze arrangement is purely mechanical and does not have time limitations or battery dependencies. This means anti-handling devices on VS-2.2 mines can remain functional indefinitely.
Q: Why does the VS-2.2 cause “mobility kills” rather than destroying vehicles? A: The VS-2.2’s 2.2 kg Composition B charge is calibrated for reliability and weight efficiency rather than maximum destruction. This charge is sufficient to destroy vehicle tracks, wheels, and road wheels, and to damage the hull underside—immobilizing the vehicle (a “mobility kill”). However, modern main battle tanks with heavy armor and blast-resistant hulls typically survive without catastrophic destruction. The tactical philosophy accepts that an immobilized vehicle blocks routes, requires recovery assets, and may be engaged by other weapons. The lighter mine weight also allows more mines to be deployed, increasing area coverage.
Q: How effective are explosive mine clearance techniques against the VS-2.2? A: Explosive mine clearance techniques are generally ineffective against the VS-2.2. The VS-N pneumatic fuze requires sustained pressure over time to inflate its internal diaphragm and release the striker. Explosive shock waves from line charges, bangalores, or demolitions last only milliseconds—insufficient to cycle the fuze mechanism. Testing shows that even direct application of explosive charges may achieve only 50% detonation probability. This blast resistance significantly complicates breaching operations and often requires alternative clearance methods such as manual removal (extremely dangerous if anti-handling devices present) or specialized neutralization techniques.
Q: What countries are known to have the VS-2.2 in their territory? A: The VS-2.2 has been documented primarily in Iraq and Kuwait, with deployment occurring during the Iran-Iraq War (1980-1988) and the Gulf War (1990-1991). Iraqi forces employed the mine extensively in defensive positions. The Imperial War Museums holds examples recovered from these conflicts. Additional undocumented deployment may have occurred in other regions where Valsella mines were exported or where Singapore-produced variants were sold.
Q: How can the VS-2.2 be distinguished from other Valsella mines? A: Key identification features include the ribbed body (unlike the smooth-sided VS-1.6), the large circular VS-N fuze on top, and its intermediate size (230mm diameter). The VS-1.6 is smaller and has distinctive circumferential cushioning bands. The VS-3.6 shares the ribbed body but is larger. The SH-55 is larger still with a more rounded, less ribbed appearance. Checking dimensions against known specifications is the most reliable identification method when visual features are ambiguous.
Q: Was the VS-2.2 produced outside Italy? A: Yes, Singapore produced VS-2.2 mines and related variants under license from Valsella. Technology transfer occurred between 1982-1986, with approximately $37 million USD in mine-related exports to Chartered Industries of Singapore. Singapore became a major mine producer and continued production after Italian legislation restricted Valsella’s activities. Singapore-produced mines may have minor manufacturing differences but share the same fundamental design and specifications.
