Overview
Nulka is currently being installed on Australian and Canadian ships. The system is effective over a full 360 degrees around the defended ship. The Aerojet Rocketdyne, a segment of L3Harris Technologies, rocket motor launches the decoy payload and hovers it away from the ship where it simulates a radar return from a large ship overlapping the “target" signal. The decoy provides a larger, more attractive target to the anti-ship missile as it moves slowly away from the ship, thus defeating the threat.
