Fuse is composed of laser proximity fuse and impact fuse (including safety & arming device). when missile and target encounters, impact fuse and proximity fuse function at the same time. With fuse-warhead matching design, impact fuse is ensured to act first and proximity fuse acts as assistant to realize proximity damage to the target on the condition that the missile cannot hit the target directly.

In the mode of impact, when the missile directly hits the target, impact fuse senses the target and immediately outputs detonating signal to detonate the warhead to achieve high-efficiency damage to the target by missile impact and integration of large quantity of fragments and shock wave produced by warhead explosion.
