What is the function of the xenon beacon on the missile?

• A. It provides a signal that can be detected by the I.R tracker in the DVO to determine the missile's position while in flight
• B. It serves as a visual beacon for ground troops during night operations
• C. It relays target coordinates to the launch unit
• D. It powers the missile's onboard electronics

Answer: (A)

The xenon beacon is there to provide a bright, detectable light signal for the infrared tracking system so the missile’s position can be determined while it’s in flight. The infrared tracker in the fire-control unit uses that beacon signal to lock onto and monitor the missile’s path, allowing the guidance system to keep guiding the missile toward its target. The beacon isn’t meant to signal troops on the ground, relay target coordinates, or power the missile’s electronics; its sole role is to give the tracking system a clear reference point in flight.
