Argon ST builds shipboard torpedo-defense decoy

shipboard torpedo defense decoyWASHINGTON – Torpedo-defense specialists at Argon ST Inc. in Smithfield, Pa., are constructing eight shipboard units for the U.S. Navy that use torpedo-spoofing decoy programs to lure enemy torpedoes away from U.S. and allied floor ships.

Officers of the Naval Sea Techniques Command in Washington introduced a $11.7 million order to Argon ST earlier this month to supply eight AN/SLQ-25A/C countermeasure decoy programs. Argon ST is an entirely owned subsidiary of the Boeing Co.

The contract modification, which incorporates spare components, is to supply improved naval floor ship protection in opposition to fashionable superior torpedoes in help of the Navy’s Undersea Defensive Warfare Program workplace.

The AN/SLQ-25A/C is a digitally managed modular electro-acoustic soft-kill countermeasure decoy system that employs an underwater towed physique acoustic projector deployed on a fiber optic tow cable from the sterns of floor warships to defend in opposition to wake-homing, acoustic homing, and wire-guided enemy torpedoes.

The AN/SLQ-25 towed decoy emits simulated ship noise just like the sounds of propellers and engines in makes an attempt to defeat a torpedo’s passive sonar. The concept is to spoof torpedoes into lacking their targets and finally sink or explode harmlessly away from the ship.

The AN/SLQ-25 is deployed on U.S. and allied floor warships, and consists of the TB-14A towed decoy system and a shipboard sign generator. The decoy emits alerts to attract incoming torpedoes away from their supposed targets.

The AN/SLQ-25A makes use of a fiber optic tow cable and winch, and consists of in depth use of economic off-the-shelf (COTS) parts. The AN/SLQ-25C is an improve to the AN/SLQ-25A, and consists of new countermeasure modes and an extended tow cable.

Since 2006, Argon has served because the lead contractor for the torpedo countermeasures transmitting set AN/SLQ-25 — generally known as Nixie. It’s a passive decoy system that gives misleading countermeasures in opposition to acoustic homing torpedoes.

On this order Argon ST will do the work in Smithfield, Pa., and must be completed by September 2019. For extra info contact Argon ST on-line at, or Naval Sea Techniques Command at
