Which missile is a short-range, heat-seeking supersonic missile?

The AIM-9M Sidewinder is a short-range infrared-guided missile designed primarily for air-to-air combat. It utilizes heat-seeking technology to home in on the infrared signature of enemy aircraft. This capability makes it highly effective at close range, where it can quickly track and engage moving targets based on their heat emissions. The missile is known for its agility and effectiveness in dogfights, primarily serving as a versatile weapon for various fighter aircraft.

In contrast, the AIM-7 Sparrow is a semi-active radar-guided missile, which relies on a different guidance method and is primarily used for medium-range engagements. The AIM-120 AMRAAM is an advanced, beyond-visual-range missile that uses active radar guidance, distinguishing it from the heat-seeking nature of the AIM-9M. The AGM-114 Hellfire is an air-to-surface missile designed for targeting ground-based threats and is not an air-to-air missile at all. Therefore, the characteristics of the AIM-9M make it the clear choice as a short-range, heat-seeking supersonic missile.
