Countermeasures Dispenser Magazine

A Countermeasures Dispenser Magazine (CDM) is a device used in military aircraft to dispense countermeasures, such as flares or chaff, to confuse or divert incoming missiles or enemy radar systems.

The CDM is typically a cylindrical or rectangular container that houses a number of countermeasures, which are small, expendable devices designed to create a decoy or diversion. These countermeasures can include infrared flares, which emit a bright heat signature to distract heat-seeking missiles, or chaff, which consists of small metallic strips that reflect radar signals and create false targets.

The CDM is usually mounted on the aircraft's wing or fuselage and is connected to the aircraft's defensive systems. When the aircraft detects an incoming threat, such as a missile or radar lock, the CDM is activated and dispenses the countermeasures. This creates a cloud of flares or chaff that confuses or diverts the threat, increasing the aircraft's chances of evading or surviving the attack.

The CDM is an essential component of an aircraft's self-defense system, providing a means of protection against various types of threats. It allows the aircraft to actively defend itself and its crew, enhancing its survivability in combat situations.
