Deployment
The decoy is launched out of a deck-mounted tube and self-inflates on the sea surface before being released to free-float past the stern to mimic a ship's radar and radio signatures. The deployment and inflation process takes seconds and the decoy is completely independent, requiring no further input from the ship. Typical ship fitment is four launchers, fitted using eight bolts and an electrical feed. The system is most effective in littoral waters with a calm sea state.
