The U.S. Naval Undersea Warfare Center Division, Keyport, Washington, is the contracting activity.
The AN/SLQ-25 Nixie and its variants are towed torpedo decoys used on US and allied warships. It consists of a towed decoy device (TB-14A) and a shipboard signal generator. The decoy emits signals to draw a torpedo away from its intended target. The Nixie attempts to defeat a torpedo’s passive sonar by emitting simulated ship noise, such as propeller and engine noise, which is more attractive than the ship to the torpedo’s sensors. Typically, larger ships may have two Nixie systems mounted on the rear of the ship to allow operation singularly or in pairs while smaller ships may have only one system.
