Saab is currently testing an electronic war nacelle called Arexis. This pod can be carried by hunters for offensive jamming missions.
Saab relied in part on the Gripen E electronic warfare system to develop an electronic warp pod with gps jammer capabilities called Arexis. Packaged in a 350 kg gondola that can be carried by a fighter such as the Gripen, Typhoon or Rafale, the Arexis system could become one of the few qualified jamming systems within NATO with the Next Generation Jammer of Raytheon but remains for the E / A-18G Growler.
The system must allow conventional fighters to perform missions of jamming enemy radar and thus protect the rest of the aircraft in flight. The special feature of the Saab system is that it can jam the very low frequency radars in the UHF and VHF bands thanks to adapted antennas. These look like wings placed on either side of the pod. The system is also equipped with an AESA antenna that can jam radar in the S and L bands. Arexis is not only used for jamming and can be used passively to detect enemy radar.
Saab is currently testing a simplified version of the system without low-frequency antennas, which can operate on radar bands between 1 and 4.5 GHz. Tests of integration of the nacelle were also carried out under the wing of a Gripen. Arexis should be tested in flight on a Gripen D. Saab believes that two-seater fighter aircraft are more suitable for carrying the carrycot due to the workload associated with the use of the system.
For the time being Arexis is developed on own funds by Saab but the Swedish manufacturer estimates that the system could be industrialized within a year if a customer wants it.
Saab is also thinking about a jammer concept that can be embedded on a drone. This system would be much less powerful but the drone could get closer to its target to perform a short-range jamming.
