What type of guidance system does the Stinger missile employ?

The Stinger missile employs infrared homing guidance, which is a key feature of its targeting and effectiveness. This guidance system works by detecting the heat signatures emitted by target aircraft, utilizing infrared sensors to lock onto and track these thermal emissions. As a result, the missile can home in on the target as it moves, making it highly effective against fast-moving aerial threats.

The infrared homing system allows Stinger missiles to operate effectively in a wide range of environments and lighting conditions, as they are less dependent on external signals or illuminators, which is a significant advantage in combat situations. This type of guidance not only improves accuracy but also reduces the chances of interference from countermeasures that an enemy might employ, such as flares or chaff.

While other guidance systems like laser, radar, or satellite guidance have their own merits and applications, they do not apply to the design and function of the Stinger missile. Laser guidance requires a laser designator that illuminates the target, radar guidance is typically used for larger systems, and satellite guidance involves tracking via GPS, which is not suitable for a shoulder-fired missile like the Stinger in dynamic combat environments. The choice of infrared homing makes the Stinger a versatile and effective air defense system.
