The Seagnat Control System (sometimes spelled SeaGnat or Sea Gnat) is a decoy system used on many NATO warships to safeguard against incoming missiles. Each unit consists of six launchers that can be loaded with different rounds, depending on the threat: * Mk214 Seduction Chaff * Mk216 Distraction Chaff * Mk245 "GIANT" IR Round * Mk251 "siren" Active Decoy Round (only on later "DLH" versions) The rounds are launched as decoys to trick incoming missiles into missing the ship or to prematurely detonating.
