What type of guidance system does the AIM-9X use?

The AIM-9X uses a passive infrared guidance system, which is pivotal for its capability to track and engage aerial targets. This system operates by detecting the heat emitted from the target, typically aircraft engines, which generate a significant infrared signature.

By utilizing passive infrared technology, the AIM-9X can home in on target heat signatures without emitting any energy signals of its own, making it harder for the target to detect and evade the missile. This enhances the element of surprise and effectiveness in combat situations, especially against enemy aircraft. The missile also incorporates advanced features such as an improved guidance section, allowing it to engage maneuvering targets effectively, further reinforcing the benefits provided by its passive infrared guidance system.

Considering the other options, active radar guidance involves the missile emitting its radar waves to locate and track targets, which is not applicable to AIM-9X. Laser guidance relies on directing a laser beam at the target, which is not how the AIM-9X operates. GPS guidance is primarily used for precision in long-range targets or ground strikes and does not align with the AIM-9X’s design, which focuses on short-range air-to-air combat.
