OVERVIEW: Corvus is a ship-launched, expendable chaff decoy designed for seduction of radar-guided anti-ship missiles. It is fired from rotating multiple-barrel 102 mm launchers to create radar-reflective clouds that lure missiles away from the ship.

DETAILS: Corvus consists of a cylindrical rotating launcher with eight 102 mm tubes mounted on a deck pedestal and controlled from the combat information centre . It deploys chaff dipoles precisely at ranges where missiles have locked on (“seduction mode”) as opposed to wider-area saturation (“distraction mode”) . Chaff dipoles are aluminum-coated fibers tuned to specific radar bands and are ejected laterally to maximize radar cross-section and decoy effectiveness .

FUNCTION:
It is launched from a deck-mounted rotating 8-tube 102 mm chaff launcher.
Once deployed, the dipoles disperse to form a compact, radar-reflective cloud.
This creates a deceptive radar target that seduces and severs missile lock, protecting the vessel.

Platforms: use aboard Royal Navy Leander and Type 21–class frigates in seduction configuration.
