OVERVIEW: Kung Feng Sea is a naval, rocket-launched chaff decoy system developed by Taiwan’s NCSIST, designed to seduce radar-guided missiles by deploying radar-reflective chaff clouds. It acts as an expendable, shipborne soft-kill defense against anti-ship missile threats.

DETAILS: The name “Kung Feng” originates from Taiwan’s indigenous multiple rocket launcher family produced by the National Chung‑Shan Institute of Science and Technology (NCSIST). The “Sea” variant adapts the land-launched Kung Feng Mk VI system into a naval configuration, equipped with chaff payload rockets instead of high-explosive or WP warheads. Typical warhead contains silver or aluminum-coated glass-fiber chaff designed to disperse at fixed distances, forming radar-reflective clouds. Developed post-Kung Feng VI in the 1980s–1990s, Kung Feng Sea offers a cost-effective indigenous countermeasure for ROC Navy ships. Technical specifics like rocket range and chaff cloud density are not publicly detailed, reflecting Taiwanese classification practices.

FONCTION: The chaff rockets are mounted in deckboard or turreted launchers on Taiwanese naval vessels; upon threat detection, rockets are launched in timed salvos to create overlapping decoy clouds, seducing inbound radar-guided missiles away from the ship.
