Which equipment is designed specifically for torpedo countermeasures?

The Nixie system is specifically designed for torpedo countermeasures. It functions by deploying a towed device that creates a synthetic target for incoming torpedoes, effectively misdirecting them away from the ship. When a torpedo is launched, the Nixie towed system releases a decoy that mimics the acoustic signature of the ship, thus enhancing the ship's defensive capabilities against torpedo attacks.

Other systems, while important for electronic warfare and countermeasures, focus on different aspects of naval defense. For instance, the SLQ-32 is an electronic warfare system that enhances situational awareness and provides defensive capabilities against missiles. The SLQ-25/25A, known for its use in anti-torpedo warfare, operates mainly as an acoustical decoy but is not as specialized as the Nixie in terms of active torpedo countermeasures. The QWQC-2 is primarily used for communications and is not designed for counteracting torpedo threats. Thus, the Nixie stands out as the system tailored explicitly for countering torpedoes.
