Chaff is primarily used against which type of missiles?

Chaff is primarily used against radar-guided missiles. This countermeasure consists of small strips of metallic or dielectric material that are released from aircraft to create false targets on radar screens. When deployed, chaff reflects radar waves, effectively confusing the missile guidance systems. Radar-guided missiles rely on reflected radar echoes to track and home in on their targets. By scattering chaff into the air, the aircraft can generate multiple false signals, making it difficult for the missile to lock onto the actual aircraft.

Understanding the context of chaff's deployment clarifies its specific purpose against radar-guided threats, as it does not provide significant protection against infrared missiles, which rely on heat signatures, or ballistic missiles, which follow a different flight path and targeting mechanism. Additionally, unmanned aerial vehicles may utilize different evasion tactics not primarily centered around radar guidance, further distinguishing the role of chaff in combat scenarios.
