OVERVIEW: The PIRATE is a 130 mm infrared seduction decoy flare designed to overwhelm incoming heat-seeking missiles by deploying a ship-like IR signature. It is compatible with NATO-standard 130 mm naval decoy launchers.

DETAILS: The PIRATE round was developed by Chemring and introduced during the 2000s as part of their naval countermeasure family. It launches via mortar-style 130 mm tubes, deploying an infrared payload tuned to both midwave (3–5 µm) and longwave (8–14 µm) IR bands to mimic ship thermal signatures. The flare is effective for seduction purposes, providing a robust thermal cloud to decoy heat-seeking missile seekers away from vulnerable platforms.

FONCTION:
Fired from 130 mm naval shower-of-flare launchers upon IR-threat detection.
Deploys a combined midwave and longwave infrared signature cloud.
Seduces incoming IR-guided missiles by presenting a stronger heat source than the host ship.
