What is Laser designation and how is it used in CAS?

• A. A designator emits a laser beam that guides a laser-guided munition to the target; requires line of sight and appropriate designation
• B. A radio signal to drop bombs
• C. A visual cue to squadron
• D. A type of flare

Answer: (A)

Laser designation marks a target with a focused laser beam so a laser-guided weapon can find and strike it. In this system, a designator—on the ground or from an aircraft—illuminates the target with a laser. The weapon carried by the attacking aircraft, typically a semi-active laser-guided munition, has a seeker that detects the reflected laser energy and uses it to steer itself to the illuminated spot.

In CAS, the TACP or forward air controller designates the target, then coordinates with the attacking aircraft to ensure the target remains illuminated and in line of sight during the weapon’s flight. The designation must stay on the target until impact, and the system works best with clear line of sight. Weather, smoke, or obscurants can degrade the laser’s effectiveness.

This is distinct from a radio signal to drop bombs, a mere visual cue, or a flare, which do not provide the necessary reflected laser energy for a guided munition to home in on the target.
