The French forces' current tactical electromagnetic intelligence (ROEM) capabilities have been developed to meet the needs expressed by each of the armies. The purpose of the tactical ROEM joint system is to provide the three services with a homogeneous system, using as many common bricks as possible, in order to guarantee operational continuity and joint use of the information collected.

The system will renew and complete, with means adapted to the new communications technologies implemented by the adversary, the current tactical ROEM capabilities, in the fields of emission detection, the characterization and localization of transmitters as well as the listening to communications, on different frequency ranges.

In order to improve interoperability and the transmission of intelligence, the joint tactical ROEM system will interface with the various means of communication, the intelligence chain, as well as the theaters of operation alerting tools.

The tactical ROEM joint system will be used by the 54th Signal Regiment, the Army's electronic support regiment, on Scorpion vehicles to replace the various tactical ROEM capabilities currently in use. It will equip the first ranks of the French Navy and the Breguet Atlantic 2 maritime patrol planes, replacing and complementing the current systems. In the Air and Space Army, it will be used in the form of deployable ground equipment to ensure the protection of air bases.
