The DHY 322 is a countermeasure system designed to protect ships, strategic sites, control centres, and large industrial centres against attacks from laser-guided weapons.
Presentation 
 The DHY 322 system comprises a high-power laser mounted on a controlled turret. The system is fully automatic and multi-directional, and operates 24 hours a day for total surveillance of the area to be protected.
The DHY 322 is connected to Laser Alert detectors indicating the origin of a hostile laser illumination and the code used for this designation. As soon as a hostile laser beam is detected on the target to protect, the DHY 322 synchronises itself with the source and creates a high-power short-range laser spot that acts as a decoy by shifting to an area in which the enemy projectile will not cause any damage.
Capable of reacting in less than on second to an attack using laser target designation, the system is effective even against the most recent generation of laser weapons.
