PARDUBICE, Czech Republic — Czech defense technology manufacturer Retia has introduced the RSB21 ReSaurion Medium, a next-generation 3D Active Electronically Scanned Array (AESA) Multi-Mission Radar (MMR). Designed as the core sensor component for the Trident Air Defence System, the ReSaurion provides advanced airspace surveillance, threat detection, and target tracking capabilities for modern ground-based air defense networks.
As airspace threats become increasingly complex, the deployment of AESA-based multi-mission radars allows air defense batteries to simultaneously detect high-altitude aircraft, low-flying cruise missiles, and small uncrewed aerial systems (UAS). The integration of the ReSaurion into the Trident ecosystem ensures that allied forces can maintain a seamless, high-fidelity real-time air picture to cue interceptors rapidly.
TECHNICAL SPECIFICATIONS: RETIA RSB21 RESAURION MEDIUM
* System Architecture: 3D Active Electronically Scanned Array (AESA) Multi-Mission Radar (MMR)
* Maximum Instrumented Range: 200 km
* Primary Role: Airspace surveillance, early warning, and weapon cueing/fire control for the Trident Air Defence System
* Electronic Beam Steering: Utilizes advanced solid-state transmit/receive modules (likely GaN-based) for rapid, continuous electronic scanning without relying solely on mechanical rotation.
* Threat Detection: Engineered to simultaneously detect and track a wide spectrum of aerial threats, including low-RCS (Radar Cross Section) targets such as loitering munitions, cruise missiles, helicopters, and fast jet aircraft.
* Mobility & Deployment: Designed for high tactical mobility, the radar can be rapidly deployed and integrated into decentralized air defense command and control (C2) networks.
The development of the RSB21 ReSaurion highlights Retia’s ongoing expansion of its advanced radar portfolio, delivering highly capable, sovereign sensor solutions for contemporary air and missile defense requirements.
