Quick Summary

A heat-seeking missile is a type of guided missile designed to track and destroy targets by following their heat emissions. These missiles are equipped with infrared sensors that detect the heat from sources like jet engines. This allows them to "home in" on their target without external commands.123

Missiles are rocket-propelled weapons that deliver explosive warheads with accuracy. While some missiles use command guidance, heat-seeking missiles employ passive guidance, meaning they rely solely on detecting energy emitted by the target itself. The development of miniaturized electronics and advanced seeker-head technology has led to smaller, more effective heat-seeking missiles, such as shoulder-fired anti-aircraft versions.23
