OVERVIEW: Barricade is a ship-launched, expendable passive countermeasure designed to defeat radar-guided threats by dispersing radar-reflective chaff clouds. It is launched from 130 mm deck-mounted systems to create false radar signatures and divert hostile missile seekers.

DETAILS: Barricade is a chaff round deployed from 130 mm naval decoy launchers such as the Mk 36 SRBOC. Each round consists of a rocket motor and a payload of metallized glass fibers or foil strips cut to radar-resonant lengths. Once launched, the round travels a programmed distance and disperses its payload to form a radar-reflective cloud that either distracts or seduces incoming radar-guided missiles. The system is produced by Chemring and its subsidiaries and is used by multiple naval forces globally.

Variants of Barricade are configured for specific engagement profiles, with differences in chaff composition, bloom patterns, and timing to adapt to a range of radar threats. Some types are optimized for rapid-area saturation while others provide tailored deception at longer ranges.

Rounds are stored in 130 mm launch tubes and fired manually or automatically through shipboard electronic warfare system integration when a radar-guided threat is detected.
