Exelis has received a subcontract from Saab to deliver electronic support measures (ESM) technology and services to Sweden.

Under the $17m agreement, Exelis will deliver its latest ES-3701 electronic warfare (EW) system for integration onto Swedish submarines. This will improve situational awareness, targeting, self-protection and surveillance.

Exelis radar and reconnaissance systems business vice-president and general manager Dave Prater said: "The ES-3701 is the ideal ESM system for submarines and surface ships, and is widely deployed with allies around the world.

"The ES-3701 is the ideal ESM system for submarines and surface ships."

"Our ESM technology will equip Sweden to handle a range of emerging threats they face, now and in the future.

Using a circular array interferometer antenna, the ES-3701 offers an accurate direction finding over a 360° azimuth and at high elevation, and maintains 100% interception.

The digital technology and modern signal processing help the system intercept, measure and identify complex signals, such as frequency modulated continuous wave, in dense radio frequency environments that include intrusive signals.

The ES-3701 forms part of a group of Exelis EW technologies aimed at enabling domestic and international institutions to execute critical missions.
