Description: The AN/SLQ-25A Surface Ship Torpedo Defense (SSTD) System is a torpedo countermeasures system developed by SensyTech for the US Navy and foreign customers surface ships. It is digitally controlled, modular design, electro-acoustic soft kill countermeasure decoy system capable of countering wake homing torpedoes, acoustic homing torpedoes, and wire guided torpedoes.

The AN/SLQ-25 Nixie introduced in the 1960s has been deployed onboard more than 300 surface ships worldwide. The SLQ-25A has been installed on US Navy surface ships such as DDG 51 destroyers and LPD 17 amphibious assault ships. It is being offered to foreign customers through the Foreign Military Sales (FMS) program. An improved model, called the SLQ-25B, is under development.

The SLQ-25A provides active/passive detection, location, threat identification of torpedoes and other acoustic targets. The towed body, the decoy which diverts the threat from the very ship, associated with the SLQ-25 connects to the management system via fiber optic cable sending signals.
