Flare (countermeasure) Facts for Kids

A C-130 fires flare countermeasures

In the military, a flare countermeasure is a very hot, burning object. It is shot out from a warplane or helicopter to protect it. Warplanes and helicopters use flares if an enemy has fired a heat-seeking missile at them.

The flare works by tricking the missile. Heat-seeking missiles are designed to fly towards the hottest thing they can find, usually the engine of an aircraft. When a flare is released, it burns extremely hot and bright. This makes the missile think the flare is the aircraft's engine, causing it to fly towards the flare instead of the plane. This helps to protect the aircraft from being hit.

Aircraft also use another countermeasure called chaff. Chaff is made of many thin strips of metal or fibers. If a radar-guided missile is fired at a plane, chaff is released. It creates a large, confusing cloud on the enemy's radar screen. This makes it very hard for the missile to find and target the actual plane or helicopter.

How Do Flares Work?

Flares are usually made of special chemicals that burn very brightly and produce a lot of heat. They are stored in small cartridges inside the aircraft. When a pilot detects a heat-seeking missile, they can press a button to release these flares.

Types of Flares

There are different kinds of flares, but they all aim to create a very hot signal. Some flares burn for a short time but are extremely bright. Others might burn a bit longer to keep the missile distracted. The goal is always to make the flare look more attractive to the missile than the aircraft itself.

Why Are Flares Important?

Flares are a vital part of an aircraft's defense system. They give pilots a chance to escape dangerous situations. Without countermeasures like flares and chaff, aircraft would be much more vulnerable to enemy missiles. They allow planes and helicopters to complete their missions more safely.
