Detonation / Trigger Mode
Electronic Time Mode:
Detonation occurs based on the preset time selected via the mechanical switch after launch. This provides tactical flexibility for different mission profiles.
Safety and Durability
Heavy Rain Resistance:
Ensures safe and reliable operation even in severe weather conditions.
High Structural Integrity:
Designed for long-term durability and consistent performance under extreme firing environments.
Dual-Stage Safety System
Arming occurs only under real firing conditions when 1,000 G setback + 2,000 RPM spin thresholds are met simultaneously.
