KEY Advantages
Mechanically Adjustable Proximity Range:
The proximity functioning height can be manually adjusted via a mechanical selector, offering reliable field usability. Detonation height can be set between 8 meters and 200 meters, enabling optimal performance for different mission types and target profiles.
Environmental & Shock Resistance
Engineered to withstand high setback forces, extreme spin rates, and severe temperature variations.
Safety Measures
Secure safety and arming mechanisms ensure safe storage, transport, and operational handling.
Detonation / Trigger Mode
Proximity Mode
Detonation occurs at the optimal distance during the approach to the target. The mechanically selectable functioning height (8–200 m) allows mission-specific destructive effectiveness.
Safety and Durability
Fail-Safe Arming Mechanism
The fuze arms only under true ballistic launch conditions, requiring both:
- 1,000 G setback
- 2,000 RPM spin
These dual thresholds ensure maximum safety during storage, handling, and transport.
Heavy Rain Resistance
Designed for safe and reliable operation under intense rainfall. High Structural
Integrity
Maintains consistent performance under high firing stresses and battlefield environments.
