Rheinmetall Air Defence AG has reached an agreement with Motorola Solutions’ Silvus Technologies unit to integrate passive radio frequency (RF) sensors into its Skynex air defence system. The integration of Silvus Technologies’ RFeye sensors will enable Skynex to detect and locate RF-emitting aerial threats without transmitting signals, helping conceal sensor positions and improve system survivability. Connected to the Skymaster command-and-control platform, the sensors will supplement conventional radar coverage and provide operators with a more comprehensive air picture alongside an electromagnetic picture of the battlespace. RFeye sensors passively detect and geolocate hostile RF emitters in real time, allowing air defence operators to maintain emissions control while gaining additional time to respond. Unlike conventional radar, which can expose its position through transmitted signals, passive RF technology supports persistent surveillance and electronic support measures. Within layered air defence networks, the sensors can provide real-time RF intelligence and assist the find, fix, track, target, engage and assess process. Rheinmetall’s cannon-based Skynex is designed for close-range air defence, particularly in situations where guided missiles may be less effective. It has a maximum firing rate of 1,000 rounds per minute and an engagement range of up to 4 kilometres (2.5 miles). The system uses programmable airburst ammunition that resists electronic countermeasures and supports accurate target engagement. Its ammunition also provides a lower-cost alternative to missile interceptors. Skynex can engage drones, missiles, and guided or unguided artillery shells, helping protect critical infrastructure and deployed military personnel.
