AN/SLQ-25 Nixie

[3][4] The AN/SLQ-25B variant includes equipment of the AN/SLQ-25A and introduced a towed array sensor to detect submarines and incoming torpedoes.

The AN/SLQ-25C has additional countermeasure modes, more reliable power amplification, a new COTS signal generator, and a longer, more functional littoral fiber optic tow cable (LFOTC) for operation in shallow water.

[8] It was to feature an open architecture, allowing it to serve as a host to other systems and support their information gathering and threat detection.

The AN/SLQ-25E addresses obsolescence issues with previous AN/SLQ-25 variants by updating the hardware and software to a COTS-based, modular, and open architecture.

working on an Active Source program called the DCL Technology Demonstrator programme, and the UK has developed and entered into service the S2170 Surface Ship Torpedo Defence system.

The LWT is a modular, digitally controlled soft kill countermeasure decoy that can defend ships against wake-homing, acoustic-homing, and wire-guided torpedoes.
