Swedish subs to get Exelis EW system
Exelis has been awarded a contract to provide Swedish submarines with the latest model of the ES-3701 electronic warfare (EW) system, the company announced on 13 January.
The contract is valued at over $17 million, and the new EW system will offer a significant capability boost in the areas of situational awareness, targeting, self-protection and surveillance.
Dave Prater, vice president and general manager of the radar and reconnaissance systems business, Exelis, said: 'The ES-3701 is the ideal ESM system for submarines and surface ships and is widely deployed with allies around the world. Our ESM technology will equip Sweden to handle a range of emerging threats they face, now and in the future.'
The ES-3701 uses a circular array interferometer antenna. This provides precise direction finding over a 360-degree azimuth and at high elevation while maintaining a 100% probability of interception.
Through digital technology and modern signal processing, the system intercepts, measures and identifies complex signals, including Frequency Modulated Continuous Wave, in dense radio frequency environments, even in the presence of interfering signals.
