Ultra Electronics is showcasing the latest models of its Defender and Deceptor series of torpedo countermeasures, with an eye on Australia’s SEA 1000 programme.

The new series, which are due for commercial production in 2018, feature programmable motion and acoustic plans that can better defeat the latest generation of torpedoes in the market today, said Douglas Burd, managing director of Ultra Electronics, in an interview with Jane’s at the Pacific 2017 exhibition in Sydney.

The Defender is a 1,000 mm by 100 mm vertically mobile countermeasure system that defeats torpedoes by luring it either upwards or downwards. The system transmits an acoustic signal to seduce torpedoes in a 360-degree direction horizontally, and can ascend and descend at a rate of about 1 m per second.

Meanwhile, the Deceptor is a fully swimmable countermeasure that works by luring an offending torpedo away from its intended target on the vertical and horizontal planes. The system is also encapsulated within a 1,000 mm by 100 mm unit, and has top swim speed of between 6 kt and 8 kt.

When deployed on submarines, the Defender and Deceptor systems can be launched at a maximum operating speed of 25 kt, and a maximum launch depth of 400 m. The countermeasures can operate in temperatures of between 0o and 30o Celsius.
