Which option accurately describes the Stinger's seeker?

• A. It uses a non-cooled infrared seeker
• B. It is a cooled infrared seeker that detects target heat and provides guidance information
• C. It relies on a radar seeker
• D. It uses a UV detector

Answer: (B)

The main idea here is how the Stinger finds and steers toward a target: its seeker is an infrared device that is cooled to cryogenic temperatures to dramatically reduce detector noise and improve sensitivity. This cooled infrared seeker passively detects the target’s heat signature and immediately translates that information into guidance signals for the missile’s flight control system, so the missile can steer toward the heat source without emitting its own signals.

That’s why this option is the best: it describes a cooled infrared seeker that detects target heat and provides the necessary guidance information. The other possibilities don’t fit because a non-cooled infrared seeker would be less sensitive and reliable, a radar seeker would involve emitting radar energy and tracking returns, and a UV detector would sense ultraviolet light—neither of which describes the Stinger’s infrared, heat-detecting, guidance-providing seeker.
