Il sistema anti-siluro AN / SLQ-61 Lightweight Tow (LWT) Torpedo Defense Mission Modul (TDMM)

Il programma Littoral Combat Ship (LCS) Mission Modules (MM) dell’US NAVY, in data 2 maggio 2020 ha annunciato il completamento con successo di due giorni di test in mare dell'AN / SLQ-61 Lightweight Tow (LWT) Torpedo Defense Mission Module; il sistema è sostanzialmente simile al / SLQ-25 sistema AN "Nixie" attualmente in dotazione all’Us Navy ed a innumerevoli marine alleate. 

L’LWT è un sistema modulare, un’esca e contromisura antisiluro digitale micidiale. Utilizza un proiettore acustico subacqueo schierato a poppa della nave su di un cavo di traino per difendere le navi contro il wake-homing, cioè il ritorno acustico dei siluri ostili filo-guidati. Il sistema LWT è significativamente più leggero rispetto all'attuale sistema "Nixie" ed ha un diverso profilo di traino, che lo rende ideale per piccole navi da guerra che operano in ambienti litorali.

Gli ultimi test hanno avuto il successo sperato dimostrando operativamente che questa tecnologia fornisce alle flotte alleate capacità di difesa dai siluri. La classe di navi LCS dell’Us Navy sono pronte quindi per l'integrazione operativa. 

Il programma sta incorporando le lezioni apprese mentre si prepara per i test formali di sviluppo e operativi a bordo di una unità LCS. La capacità di difesa dai siluri fornita dal TDMM è prevista per l'eventuale dispiegamento su tutte le navi LCS e potenzialmente su altri piccole unità combattenti.

US Navy’s LCS programme completes AN/SLQ-61 LWT TDMM testing

The US Navy’s Littoral Combat Ship (LCS) Mission Modules (MM) programme has successfully completed the at-sea testing of the AN/SLQ-61 lightweight tow (LWT) Torpedo Defense Mission Module (TDMM).

A series of tests were conducted over a two-day period as part of the initiative, which marked the final at-sea trial of the LWT TDMM on-board a commercial vessel.

The LCS MM programme has been primarily designed to prepare the US Navy for the integration of the TDMM, as well as formal developmental and operational testing on-board an LCS.

"The TDMM is intended to provide a torpedo defence capability that could be eventually deployed on-board all US Navy LCS units."

The TDMM is intended to provide a torpedo defence capability that could be eventually deployed on-board all US Navy LCS units, as well as other small combatant vessels in future.

LCS Mission Modules programme manager US Navy captain Theodore Zobel said: “This test was highly successful and demonstrated that this technology, which provides critical torpedo defence capability for the LCS class of ships, is ready for integration aboard an LCS.”


The AN/SLQ-61 LWT is a modular, digitally controlled, soft kill countermeasure decoy solution, which is similar to the AN/SLQ-25 Nixie system that is currently integrated on-board the navy fleet.

The LWT employs an underwater acoustic projector, which is deployed from the vessel’s stern on a tow cable in order to defend the navy ships against ‘wake-homing, acoustic homing and wire-guided enemy torpedoes’.U.S. Navy Completes Lightweight Torpedo Defense Mission Module Testing.

The Littoral Combat Ship (LCS) Mission Modules (MM) program announced the successful completion of two days of at-sea testing of the AN/SLQ-61 Lightweight Tow (LWT) Torpedo Defense Mission Module (TDMM), May 2.

Similar to the AN/SLQ-25 "Nixie" system currently installed in the fleet, the LWT is a modular, digitally controlled soft kill countermeasure decoy system. It employs an underwater acoustic projector deployed from the ship's stern on a tow cable to defend ships against wake-homing, acoustic homing, and wire-guided enemy torpedoes. The LWT system is significantly lighter in weight than the current "Nixie" system and has a different tow profile, making it ideally suited for small combatant warships operating in littoral environments.

"This test was highly successful and demonstrated that this technology, which provides critical torpedo defense capability for the LCS class of ships, is ready for integration aboard an LCS," said Capt. Theodore Zobel, LCS Mission Modules program manager.

The test event was the final at-sea test on a commercial vessel. The program is incorporating lessons learned from this event as it prepares for TDMM integration and formal developmental and operational tests aboard an LCS. The torpedo defense capability the TDMM provides is envisioned for eventual deployment on all LCS ships, and potentially other small combatants.
