What type of guidance system does the Stinger missile utilize?

The Stinger missile utilizes infrared homing guidance, which is a key feature that allows it to effectively target and engage various aerial threats. This type of guidance system is designed to detect the heat emitted by the engines of enemy aircraft, including helicopters and jets. When launched, the missile's infrared seeker locks onto the thermal signature, enabling it to follow and home in on the target.

The infrared homing capability is particularly advantageous for short-range air defense because it allows for quick targeting and a more covert engagement without emitting radar signals that could give away the missile's position. This stealthiness is crucial in combat scenarios, allowing the user to remain undetected by enemy radar systems.

Other guidance systems mentioned do not apply to the Stinger missile. For example, laser guidance relies on designating a target with a laser beam, which is not characteristic of the Stinger's operational profile. Radar guidance uses radio waves to track and guide a missile, which also does not pertain to the Stinger's technology. Lastly, GPS guidance is suited for long-range missile systems and tactical navigation rather than the close-range, high-speed engagements typical of the Stinger's intended use.
