Singing Torpedoes to Sleep

Posted August 19, 2014 at 2:31pm

Nixie, a siren-like creature of European legends, is said to sing a sweet song that entrances listeners and lures them away. Boeing’s modern-day ‘Nixie,’ or the AN/SLQ-25, sings its sweet lullaby confusing the torpedo’s sensors as it mimics the acoustic signature of the surface ship it protects. As the torpedo is lured away from the ship and its crew, it falls into a peaceful slumber at the bottom of the sea as its fuel is depleted.  

Boeing subsidiary Argon ST has been providing navies around the world with the Nixie surface ship torpedo defense system for more than a decade, delivering more than 400 systems to the US Navy and coalition partners worldwide. This summer, the company enters a new chapter in producing high-end acoustics and anti-submarine warfare capabilities by bringing production of the voice of the Nixie system, the singing towed counter measure, in-house for the first time.  

With this move, Argon ST expands into a whole new line of work to support Nixie customers with additional towed body repair capabilities and modernization of existing devices. In addition to opening doors to new innovation of the Nixie system through enhancements to the towed acoustics counter measure, the company is better positioned to expand system capabilities to new sensor payloads beyond torpedo defense to meet future customer and mission requirements.
