OVERVIEW: The Syllex is a naval chaff launcher system developed by France in the late 1970s. It is designed to deploy radar-reflective chaff for ship defense against radar-guided missile threats.

DETAILS: The Syllex system consists of fixed-angle deck-mounted launch tubes capable of firing salvos of chaff rockets to form radar-reflective clouds. It was used aboard select French Navy vessels during the Cold War era. The system was integrated with onboard electronic support measures for automatic deployment in response to radar emissions. Syllex contributed to a layered countermeasures suite alongside towed decoys and internal threat detection equipment.

FONCTION:
Radar warning detection triggers chaff deployment.
Chaff rockets are fired in salvos from deck-mounted launchers.
Dispensed chaff forms radar-reflective clouds to seduce incoming radar-guided missiles.
