KEY Advantages

High-Precision Impact Activation

Provides instantaneous detonation at the exact moment of target contact, ensuring maximum penetration and destructive effect.

  • Dual-Safety Arming Logic
  • Rugged Mechanical Construction
  • STANAG-Compatible Interface

 

Robust Environmental & Shock Tolerance

Designed to withstand severe launch conditions of 122 mm rockets, including high vibration, temperature changes, and mechanical shock.

Fail-Safe Arming Mechanism

The fuze arms only when both conditions are met:

  • ≥ 20 G setback
  • ≥ 400 RPM spin

This ensures absolute safety during handling, storage, and transport.

 

Detonation / Trigger Mode

Super Quick Impact Mode

Detonates immediately upon physical contact with the target surface. This ensures rapid energy transfer and optimal lethality against structures, fortifications, and ground impact targets.

 

Safety and Durability

Environmental Reliability

Performs flawlessly in heavy rain, humidity, vibration, and harsh battlefield conditions.

High Structural Integrity

Reinforced mechanical components ensure dependable operation even during high-intensity firing sequences

Fail-Safe Arming Mechanism

The fuze arms only under true ballistic launch conditions, meeting both the 1,000 G setback and 2,000 RPM spin requirements simultaneously.
