How long does the seeker take to activate?

• A. 5-8 seconds
• B. 20-30 seconds
• C. 10-15 seconds
• D. 1 minute

Answer: (C)

Seeker activation time is the warm-up and stabilization period the infrared sensing system needs before it can reliably lock onto a target. The sensor must reach operating conditions, calibrate optics, and establish a valid track through image processing, which takes about 10 to 15 seconds. This window is short enough to keep engagement timely, yet long enough to prevent mis-tracking or false targets that could occur if you rushed the process. Going much faster risks the seeker not coming online properly, while waiting longer would introduce unnecessary delays and increase vulnerability to countermeasures or target maneuvers. Therefore, 10-15 seconds is the typical activation duration.
